+ *
+ * 1) The following types are of fixed size for all targets (16/32/64):
+ *
+ * u8 Logical boolean
+ *
+ * u8 8-bit (1 byte) unsigned value
+ * u16 16-bit (2 byte) unsigned value
+ * u32 32-bit (4 byte) unsigned value
+ * u64 64-bit (8 byte) unsigned value
+ *
+ * s16 16-bit (2 byte) signed value
+ * s32 32-bit (4 byte) signed value
+ * s64 64-bit (8 byte) signed value
+ *
+ * COMPILER_DEPENDENT_UINT64/s64 - These types are defined in the
+ * compiler-dependent header(s) and were introduced because there is no common
+ * 64-bit integer type across the various compilation models, as shown in
+ * the table below.
+ *
+ * Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
+ * char 8 8 8 8 8 8
+ * short 16 16 16 16 16 16
+ * _int32 32
+ * int 32 64 32 32 16 16
+ * long 64 64 32 32 32 32
+ * long long 64 64
+ * pointer 64 64 64 32 32 32
+ *
+ * Note: ILP64 and LP32 are currently not supported.
+ *
+ *
+ * 2) These types represent the native word size of the target mode of the
+ * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
+ * usually used for memory allocation, efficient loop counters, and array
+ * indexes. The types are similar to the size_t type in the C library and are
+ * required because there is no C type that consistently represents the native
+ * data width. acpi_size is needed because there is no guarantee that a
+ * kernel-level C library is present.

+/* Comment by Rik:
+ *
+ * For some background on GF(2^128) see for example:
+ * http://csrc.nist.gov/groups/ST/toolkit/BCM/documents/proposedmodes/gcm/gcm-revised-spec.pdf
+ *
+ * The elements of GF(2^128) := GF(2)[X]/(X^128-X^7-X^2-X^1-1) can
+ * be mapped to computer memory in a variety of ways. Let's examine
+ * three common cases.
+ *
+ * Take a look at the 16 binary octets below in memory order. The msb's
+ * are left and the lsb's are right. char b[16] is an array and b[0] is
+ * the first octet.
+ *
+ * 80000000 00000000 00000000 00000000 .... 00000000 00000000 00000000
+ * b[0] b[1] b[2] b[3] b[13] b[14] b[15]
+ *
+ * Every bit is a coefficient of some power of X. We can store the bits
+ * in every byte in little-endian order and the bytes themselves also in
+ * little endian order. I will call this lle (little-little-endian).
+ * The above buffer represents the polynomial 1, and X^7+X^2+X^1+1 looks
+ * like 11100001 00000000 .... 00000000 = { 0xE1, 0x00, }.
+ * This format was originally implemented in gf128mul and is used
+ * in GCM (Galois/Counter mode) and in ABL (Arbitrary Block Length).
+ *
+ * Another convention says: store the bits in bigendian order and the
+ * bytes also. This is bbe (big-big-endian). Now the buffer above
+ * represents X^127. X^7+X^2+X^1+1 looks like 00000000 .... 10000111,
+ * b[15] = 0x87 and the rest is 0. LRW uses this convention and bbe
+ * is partly implemented.
+ *
+ * Both of the above formats are easy to implement on big-endian
+ * machines.
+ *
+ * EME (which is patent encumbered) uses the ble format (bits are stored
+ * in big endian order and the bytes in little endian). The above buffer
+ * represents X^7 in this case and the primitive polynomial is b[0] = 0x87.
+ *
+ * The common machine word-size is smaller than 128 bits, so to make
+ * an efficient implementation we must split into machine word sizes.
+ * This file uses one 32bit for the moment. Machine endianness comes into
+ * play. The lle format in relation to machine endianness is discussed
+ * below by the original author of gf128mul Dr Brian Gladman.
+ *
+ * Let's look at the bbe and ble format on a little endian machine.
+ *
+ * bbe on a little endian machine u32 x[4]:
+ *
+ * MS x[0] LS MS x[1] LS
+ * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ * 103..96 111.104 119.112 127.120 71...64 79...72 87...80 95...88
+ *
+ * MS x[2] LS MS x[3] LS
+ * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ * 39...32 47...40 55...48 63...56 07...00 15...08 23...16 31...24
+ *
+ * ble on a little endian machine
+ *
+ * MS x[0] LS MS x[1] LS
+ * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ * 31...24 23...16 15...08 07...00 63...56 55...48 47...40 39...32
+ *
+ * MS x[2] LS MS x[3] LS
+ * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ * 95...88 87...80 79...72 71...64 127.120 199.112 111.104 103..96
+ *
+ * Multiplications in GF(2^128) are mostly bit-shifts, so you see why
+ * ble (and lbe also) are easier to implement on a little-endian
+ * machine than on a big-endian machine. The converse holds for bbe
+ * and lle.
+ *
+ * Note: to have good alignment, it seems to me that it is sufficient
+ * to keep elements of GF(2^128) in type u64[2]. On 32-bit wordsize
+ * machines this will automatically aligned to wordsize and on a 64-bit
+ * machine also.
+ */
+/* Multiply a GF128 field element by x. Field elements are held in arrays
+ of bytes in which field bits 8n..8n + 7 are held in byte[n], with lower
+ indexed bits placed in the more numerically significant bit positions
+ within bytes.
+
+ On little endian machines the bit indexes translate into the bit
+ positions within four 32-bit words in the following way
+
+ MS x[0] LS MS x[1] LS
+ ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ 24...31 16...23 08...15 00...07 56...63 48...55 40...47 32...39

+ * the internal structures used during the entire duration of the whole
+ * transformation. No data processing happens at this point.
+ * @update: Push a chunk of data into the driver for transformation. This
+ * function actually pushes blocks of data from upper layers into the
+ * driver, which then passes those to the hardware as seen fit. This
+ * function must not finalize the HASH transformation by calculating the
+ * final message digest as this only adds more data into the
+ * transformation. This function shall not modify the transformation
+ * context, as this function may be called in parallel with the same
+ * transformation object. Data processing can happen synchronously
+ * [SHASH] or asynchronously [AHASH] at this point.
+ * @final: Retrieve result from the driver. This function finalizes the
+ * transformation and retrieves the resulting hash from the driver and
+ * pushes it back to upper layers. No data processing happens at this
+ * point.
+ * @finup: Combination of @update and @final. This function is effectively a
+ * combination of @update and @final calls issued in sequence. As some
+ * hardware cannot do @update and @final separately, this callback was
+ * added to allow such hardware to be used at least by IPsec. Data
+ * processing can happen synchronously [SHASH] or asynchronously [AHASH]
+ * at this point.
+ * @digest: Combination of @init and @update and @final. This function
+ * effectively behaves as the entire chain of operations, @init,
+ * @update and @final issued in sequence. Just like @finup, this was
+ * added for hardware which cannot do even the @finup, but can only do
+ * the whole transformation in one run. Data processing can happen
+ * synchronously [SHASH] or asynchronously [AHASH] at this point.
+ * @setkey: Set optional key used by the hashing algorithm. Intended to push
+ * optional key used by the hashing algorithm from upper layers into
+ * the driver. This function can store the key in the transformation
+ * context or can outright program it into the hardware. In the former
+ * case, one must be careful to program the key into the hardware at
+ * appropriate time and one must be careful that .setkey() can be
+ * called multiple times during the existence of the transformation
+ * object. Not all hashing algorithms do implement this function as it
+ * is only needed for keyed message digests. SHAx/MDx/CRCx do NOT
+ * implement this function. HMAC(MDx)/HMAC(SHAx)/CMAC(AES) do implement
+ * this function. This function must be called before any other of the
+ * @init, @update, @final, @finup, @digest is called. No data
+ * processing happens at this point.
+ * @export: Export partial state of the transformation. This function dumps the
+ * entire state of the ongoing transformation into a provided block of
+ * data so it can be @import 'ed back later on. This is useful in case
+ * you want to save partial result of the transformation after
+ * processing certain amount of data and reload this partial result
+ * multiple times later on for multiple re-use. No data processing
+ * happens at this point.
+ * @import: Import partial state of the transformation. This function loads the
+ * entire state of the ongoing transformation from a provided block of
+ * data so the transformation can continue from this point onward. No
+ * data processing happens at this point.

+ * are executed via the .transfer() function. A pointer to a drm_dp_aux_msg
+ * structure describing the transaction is passed into this function. Upon
+ * success, the implementation should return the number of payload bytes
+ * that were transferred, or a negative error-code on failure. Helpers
+ * propagate errors from the .transfer() function, with the exception of
+ * the -EBUSY error, which causes a transaction to be retried. On a short,
+ * helpers will return -EPROTO to make it simpler to check for failure.
+ *
+ * An AUX channel can also be used to transport I2C messages to a sink. A
+ * typical application of that is to access an EDID that's present in the
+ * sink device. The .transfer() function can also be used to execute such
+ * transactions. The drm_dp_aux_register_i2c_bus() function registers an
+ * I2C adapter that can be passed to drm_probe_ddc(). Upon removal, drivers
+ * should call drm_dp_aux_unregister_i2c_bus() to remove the I2C adapter.
+ * The I2C adapter uses long transfers by default; if a partial response is
+ * received, the adapter will drop down to the size given by the partial
+ * response for this transaction only.
+ *
+ * Note that the aux helper code assumes that the .transfer() function
+ * only modifies the reply field of the drm_dp_aux_msg structure. The
+ * retry logic and i2c helpers assume this is the case.

+ * This header provides constants for binding nvidia,tegra124-car or
+ * nvidia,tegra132-car.
+ *
+ * The first 192 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
+ * registers. These IDs often match those in the CAR's RST_DEVICES registers,
+ * but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
+ * this case, those clocks are assigned IDs above 185 in order to highlight
+ * this issue. Implementations that interpret these clock IDs as bit values
+ * within the CLK_OUT_ENB or RST_DEVICES registers should be careful to
+ * explicitly handle these special cases.
+ *
+ * The balance of the clocks controlled by the CAR are assigned IDs of 185 and
+ * above.

+ * generation mode (including PWM) or "capture" mode (to time events). In
+ * both modes, behavior can be configured in many ways.

+ * Each timer has two I/O pins, TIOA and TIOB. Waveform mode uses TIOA as a
+ * PWM output, and TIOB as either another PWM or as a trigger. Capture mode

+ *
+ * Common interface definitions for making balloon pages movable by compaction.
+ *
+ * Despite being perfectly possible to perform ballooned pages migration, they
+ * make a special corner case to compaction scans because balloon pages are not
+ * enlisted at any LRU list like the other pages we do compact / migrate.
+ *
+ * As the page isolation scanning step a compaction thread does is a lockless
+ * procedure (from a page standpoint), it might bring some racy situations while
+ * performing balloon page compaction. In order to sort out these racy scenarios
+ * and safely perform balloon's page compaction and migration we must, always,
+ * ensure following these three simple rules:
+ *
+ * i. when updating a balloon's page ->mapping element, strictly do it under
+ * the following lock order, independently of the far superior
+ * locking scheme (lru_lock, balloon_lock):
+ * +-page_lock(page);
+ * +--spin_lock_irq(&b_dev_info->pages_lock);
+ * ... page->mapping updates here ...
+ *
+ * ii. before isolating or dequeueing a balloon page from the balloon device
+ * pages list, the page reference counter must be raised by one and the
+ * extra refcount must be dropped when the page is enqueued back into
+ * the balloon device page list, thus a balloon page keeps its reference
+ * counter raised only while it is under our special handling;
+ *
+ * iii. after the lockless scan step have selected a potential balloon page for
+ * isolation, re-test the PageBalloon mark and the PagePrivate flag
+ * under the proper page lock, to ensure isolating a valid balloon page
+ * (not yet isolated, nor under release procedure)
+ *
+ * iv. isolation or dequeueing procedure must clear PagePrivate flag under
+ * page lock together with removing page from balloon device page list.
+ *
+ * The functions provided by this interface are placed to help on coping with
+ * the aforementioned balloon page corner case, as well as to ensure the simple
+ * set of exposed rules are satisfied while we are dealing with balloon pages
+ * compaction / migration.

+ * DOC: B+Tree basics
+ *
+ * A B+Tree is a data structure for looking up arbitrary (currently allowing
+ * unsigned long, u32, u64 and 2 * u64) keys into pointers. The data structure
+ * is described at http://en.wikipedia.org/wiki/B-tree, we currently do not
+ * use binary search to find the key on lookups.
+ *
+ * Each B+Tree consists of a head, that contains bookkeeping information and
+ * a variable number (starting with zero) nodes. Each node contains the keys
+ * and pointers to sub-nodes, or, for leaf nodes, the keys and values for the
+ * tree entries.
+ *
+ * Each node in this implementation has the following layout:
+ * [key1, key2, ..., keyN] [val1, val2, ..., valN]
+ *
+ * Each key here is an array of unsigned longs, geo->no_longs in total. The
+ * number of keys and values (N) is geo->no_pairs.

+ * "Frags" are a way to describe a subset of a 32-bit number space,
+ * using a mask and a value to match against that mask. Any given frag
+ * (subset of the number space) can be partitioned into 2^n sub-frags.
+ *
+ * Frags are encoded into a 32-bit word:
+ * 8 upper bits = "bits"
+ * 24 lower bits = "value"
+ * (We could go to 5+27 bits, but who cares.)
+ *
+ * We use the _most_ significant bits of the 24 bit value. This makes
+ * values logically sort.
+ *
+ * Unfortunately, because the "bits" field is still in the high bits, we
+ * can't sort encoded frags numerically. However, it does allow you
+ * to feed encoded frags as values into frag_contains_value.

+ * The default hierarchy is the v2 interface of cgroup and this function

+ * cases where a subsystem should behave differnetly depending on the
+ * interface version.
+ *
+ * The set of behaviors which change on the default hierarchy are still
+ * being determined and the mount option is prefixed with __DEVEL__.
+ *
+ * List of changed behaviors:
+ *
+ * - Mount options "noprefix", "xattr", "clone_children", "release_agent"
+ * and "name" are disallowed.
+ *
+ * - When mounting an existing superblock, mount options should match.
+ *
+ * - Remount is disallowed.
+ *
+ * - rename(2) is disallowed.
+ *
+ * - "tasks" is removed. Everything should be at process granularity. Use
+ * "cgroup.procs" instead.
+ *
+ * - "cgroup.procs" is not sorted. pids will be unique unless they got
+ * recycled inbetween reads.
+ *
+ * - "release_agent" and "notify_on_release" are removed. Replacement
+ * notification mechanism will be implemented.
+ *
+ * - "cgroup.clone_children" is removed.
+ *
+ * - "cgroup.subtree_populated" is available. Its value is 0 if the cgroup
+ * and its descendants contain no task; otherwise, 1. The file also
+ * generates kernfs notification which can be monitored through poll and
+ * [di]notify when the value of the file changes.
+ *
+ * - cpuset: tasks will be kept in empty cpusets when hotplug happens and
+ * take masks of ancestors with non-empty cpus/mems, instead of being
+ * moved to an ancestor.
+ *
+ * - cpuset: a task can be moved into an empty cpuset, and again it takes
+ * masks of ancestors.
+ *
+ * - memcg: use_hierarchy is on by default and the cgroup file for the flag
+ * is not created.
+ *
+ * - blkcg: blk-throttle becomes properly hierarchical.

+/**
+ * struct clk_ops - Callback operations for hardware clocks; these are to
+ * be provided by the clock implementation, and will be called by drivers
+ * through the clk_* api.
+ *
+ * @prepare: Prepare the clock for enabling. This must not return until
+ * the clock is fully prepared, and it's safe to call clk_enable.
+ * This callback is intended to allow clock implementations to
+ * do any initialisation that may sleep. Called with
+ * prepare_lock held.
+ *
+ * @unprepare: Release the clock from its prepared state. This will typically
+ * undo any work done in the @prepare callback. Called with
+ * prepare_lock held.
+ *
+ * @is_prepared: Queries the hardware to determine if the clock is prepared.
+ * This function is allowed to sleep. Optional, if this op is not
+ * set then the prepare count will be used.
+ *
+ * @unprepare_unused: Unprepare the clock atomically. Only called from
+ * clk_disable_unused for prepare clocks with special needs.
+ * Called with prepare mutex held. This function may sleep.
+ *
+ * @enable: Enable the clock atomically. This must not return until the
+ * clock is generating a valid clock signal, usable by consumer
+ * devices. Called with enable_lock held. This function must not
+ * sleep.
+ *
+ * @disable: Disable the clock atomically. Called with enable_lock held.
+ * This function must not sleep.
+ *
+ * @is_enabled: Queries the hardware to determine if the clock is enabled.
+ * This function must not sleep. Optional, if this op is not
+ * set then the enable count will be used.
+ *
+ * @disable_unused: Disable the clock atomically. Only called from
+ * clk_disable_unused for gate clocks with special needs.
+ * Called with enable_lock held. This function must not
+ * sleep.
+ *
+ * @recalc_rate Recalculate the rate of this clock, by querying hardware. The
+ * parent rate is an input parameter. It is up to the caller to
+ * ensure that the prepare_mutex is held across this call.
+ * Returns the calculated rate. Optional, but recommended - if
+ * this op is not set then clock rate will be initialized to 0.
+ *
+ * @round_rate: Given a target rate as input, returns the closest rate actually
+ * supported by the clock. The parent rate is an input/output
+ * parameter.
+ *
+ * @determine_rate: Given a target rate as input, returns the closest rate
+ * actually supported by the clock, and optionally the parent clock
+ * that should be used to provide the clock rate.
+ *
+ * @set_parent: Change the input source of this clock; for clocks with multiple
+ * possible parents specify a new parent by passing in the index
+ * as a u8 corresponding to the parent in either the .parent_names
+ * or .parents arrays. This function in affect translates an
+ * array index into the value programmed into the hardware.
+ * Returns 0 on success, -EERROR otherwise.
+ *
+ * @get_parent: Queries the hardware to determine the parent of a clock. The
+ * return value is a u8 which specifies the index corresponding to
+ * the parent clock. This index can be applied to either the
+ * .parent_names or .parents arrays. In short, this function
+ * translates the parent value read from hardware into an array
+ * index. Currently only called when the clock is initialized by
+ * __clk_init. This callback is mandatory for clocks with
+ * multiple parents. It is optional (and unnecessary) for clocks
+ * with 0 or 1 parents.
+ *
+ * @set_rate: Change the rate of this clock. The requested rate is specified
+ * by the second argument, which should typically be the return
+ * of .round_rate call. The third argument gives the parent rate
+ * which is likely helpful for most .set_rate implementation.
+ * Returns 0 on success, -EERROR otherwise.
+ *
+ * @set_rate_and_parent: Change the rate and the parent of this clock. The
+ * requested rate is specified by the second argument, which
+ * should typically be the return of .round_rate call. The
+ * third argument gives the parent rate which is likely helpful
+ * for most .set_rate_and_parent implementation. The fourth
+ * argument gives the parent index. This callback is optional (and
+ * unnecessary) for clocks with 0 or 1 parents as well as
+ * for clocks that can tolerate switching the rate and the parent
+ * separately via calls to .set_parent and .set_rate.
+ * Returns 0 on success, -EERROR otherwise.
+ *
+ * @recalc_accuracy: Recalculate the accuracy of this clock. The clock accuracy
+ * is expressed in ppb (parts per billion). The parent accuracy is
+ * an input parameter.
+ * Returns the calculated accuracy. Optional - if this op is not
+ * set then clock accuracy will be initialized to parent accuracy
+ * or 0 (perfect clock) if clock has no parent.
+ *
+ * @get_phase: Queries the hardware to get the current phase of a clock.
+ * Returned values are 0-359 degrees on success, negative
+ * error codes on failure.
+ *
+ * @set_phase: Shift the phase this clock signal in degrees specified
+ * by the second argument. Valid values for degrees are
+ * 0-359. Return 0 on success, otherwise -EERROR.
+ *
+ * @init: Perform platform-specific initialization magic.
+ * This is not not used by any of the basic clock types.
+ * Please consider other ways of solving initialization problems
+ * before using this callback, as its use is discouraged.
+ *
+ * @debug_init: Set up type-specific debugfs entries for this clock. This
+ * is called once, after the debugfs directory entry for this
+ * clock has been created. The dentry pointer representing that
+ * directory is provided as an argument. Called with
+ * prepare_lock held. Returns 0 on success, -EERROR otherwise.
+ *
+ *
+ * The clk_enable/clk_disable and clk_prepare/clk_unprepare pairs allow
+ * implementations to split any work between atomic (enable) and sleepable
+ * (prepare) contexts. If enabling a clock requires code that might sleep,
+ * this must be done in clk_prepare. Clock enable code that will never be
+ * called in a sleepable context may be implemented in clk_enable.
+ *
+ * Typically, drivers will call clk_prepare when a clock may be needed later
+ * (eg. when a device is opened), and clk_enable when the clock is actually
+ * required (eg. from an interrupt). Note that clk_prepare MUST have been
+ * called before clk_enable.

+/**
+ * cnt32_to_63 - Expand a 32-bit counter to a 63-bit counter
+ * @cnt_lo: The low part of the counter
+ *
+ * Many hardware clock counters are only 32 bits wide and therefore have
+ * a relatively short period making wrap-arounds rather frequent. This
+ * is a problem when implementing sched_clock() for example, where a 64-bit
+ * non-wrapping monotonic value is expected to be returned.
+ *
+ * To overcome that limitation, let's extend a 32-bit counter to 63 bits
+ * in a completely lock free fashion. Bits 0 to 31 of the clock are provided
+ * by the hardware while bits 32 to 62 are stored in memory. The top bit in
+ * memory is used to synchronize with the hardware clock half-period. When
+ * the top bit of both counters (hardware and in memory) differ then the
+ * memory is updated with a new value, incrementing it when the hardware
+ * counter wraps around.
+ *
+ * Because a word store in memory is atomic then the incremented value will
+ * always be in synch with the top bit indicating to any potential concurrent
+ * reader if the value in memory is up to date or not with regards to the
+ * needed increment. And any race in updating the value in memory is harmless
+ * as the same value would simply be stored more than once.
+ *
+ * The restrictions for the algorithm to work properly are:
+ *
+ * 1) this code must be called at least once per each half period of the
+ * 32-bit counter;
+ *
+ * 2) this code must not be preempted for a duration longer than the
+ * 32-bit counter half period minus the longest period between two
+ * calls to this code;
+ *
+ * Those requirements ensure proper update to the state bit in memory.
+ * This is usually not a problem in practice, but if it is then a kernel
+ * timer should be scheduled to manage for this code to be executed often
+ * enough.
+ *
+ * And finally:
+ *
+ * 3) the cnt_lo argument must be seen as a globally incrementing value,
+ * meaning that it should be a direct reference to the counter data which
+ * can be evaluated according to a specific ordering within the macro,
+ * and not the result of a previous evaluation stored in a variable.
+ *
+ * For example, this is wrong:
+ *
+ * u32 partial = get_hw_count();
+ * u64 full = cnt32_to_63(partial);
+ * return full;
+ *
+ * This is fine:
+ *
+ * u64 full = cnt32_to_63(get_hw_count());
+ * return full;
+ *
+ * Note that the top bit (bit 63) in the returned value should be considered
+ * as garbage. It is not cleared here because callers are likely to use a
+ * multiplier on the returned value which can get rid of the top bit
+ * implicitly by making the multiplier even, therefore saving on a runtime
+ * clear-bit instruction. Otherwise caller must remember to clear the top
+ * bit explicitly.

+ * cpu_active_mask - has bit 'cpu' set iff cpu available to migration
+ *
+ * If !CONFIG_HOTPLUG_CPU, present == possible, and active == online.
+ *
+ * The cpu_possible_mask is fixed at boot time, as the set of CPU id's
+ * that it is possible might ever be plugged in at anytime during the
+ * life of that system boot. The cpu_present_mask is dynamic(*),
+ * representing which CPUs are currently plugged in. And
+ * cpu_online_mask is the dynamic subset of cpu_present_mask,
+ * indicating those CPUs available for scheduling.
+ *
+ * If HOTPLUG is enabled, then cpu_possible_mask is forced to have
+ * all NR_CPUS bits set, otherwise it is just the set of CPUs that
+ * ACPI reports present at boot.
+ *
+ * If HOTPLUG is enabled, then cpu_present_mask varies dynamically,
+ * depending on what ACPI reports as currently plugged in, otherwise
+ * cpu_present_mask is just a copy of cpu_possible_mask.
+ *
+ * (*) Well, cpu_present_mask is dynamic in the hotplug case. If not
+ * hotplug, it's a copy of cpu_possible_mask, hence fixed at boot.
+ *
+ * Subtleties:
+ * 1) UP arch's (NR_CPUS == 1, CONFIG_SMP not defined) hardcode
+ * assumption that their single CPU is online. The UP
+ * cpu_{online,possible,present}_masks are placebos. Changing them
+ * will have no useful affect on the following num_*_cpus()
+ * and cpu_*() macros in the UP case. This ugliness is a UP
+ * optimization - don't waste any instructions or memory references
+ * asking if you're online or how many CPUs there are if there is

+ * algorithm.
+ * @cra_blocksize: Minimum block size of this transformation. The size in bytes

+ * In case of HASH transformation, it is possible for a smaller

+ * transformation, in case of any other transformation type, an
+ * error will be returned upon any attempt to transform smaller
+ * than @cra_blocksize chunks.
+ * @cra_ctxsize: Size of the operational context of the transformation. This
+ * value informs the kernel crypto API about the memory size
+ * needed to be allocated for the transformation context.
+ * @cra_alignmask: Alignment mask for the input and output data buffer. The data
+ * buffer containing the input data for the algorithm must be
+ * aligned to this alignment mask. The data buffer for the
+ * output data must be aligned to this alignment mask. Note that
+ * the Crypto API will do the re-alignment in software, but
+ * only under special conditions and there is a performance hit.
+ * The re-alignment happens at these occasions for different
+ * @cra_u types: cipher -- For both input data and output data
+ * buffer; ahash -- For output hash destination buf; shash --
+ * For output hash destination buf.
+ * This is needed on hardware which is flawed by design and
+ * cannot pick data from arbitrary addresses.
+ * @cra_priority: Priority of this transformation implementation. In case
+ * multiple transformations with same @cra_name are available to
+ * the Crypto API, the kernel will use the one with highest
+ * @cra_priority.
+ * @cra_name: Generic name (usable by multiple implementations) of the
+ * transformation algorithm. This is the name of the transformation
+ * itself. This field is used by the kernel when looking up the
+ * providers of particular transformation.
+ * @cra_driver_name: Unique name of the transformation provider. This is the
+ * name of the provider of the transformation. This can be any
+ * arbitrary value, but in the usual case, this contains the
+ * name of the chip or provider and the name of the
+ * transformation algorithm.
+ * @cra_type: Type of the cryptographic transformation. This is a pointer to
+ * struct crypto_type, which implements callbacks common for all
+ * trasnformation types. There are multiple options:
+ * &crypto_blkcipher_type, &crypto_ablkcipher_type,
+ * &crypto_ahash_type, &crypto_aead_type, &crypto_rng_type.
+ * This field might be empty. In that case, there are no common
+ * callbacks. This is the case for: cipher, compress, shash.
+ * @cra_u: Callbacks implementing the transformation. This is a union of
+ * multiple structures. Depending on the type of transformation selected
+ * by @cra_type and @cra_flags above, the associated structure must be
+ * filled with callbacks. This field might be empty. This is the case
+ * for ahash, shash.
+ * @cra_init: Initialize the cryptographic transformation object. This function
+ * is used to initialize the cryptographic transformation object.
+ * This function is called only once at the instantiation time, right
+ * after the transformation context was allocated. In case the
+ * cryptographic hardware has some special requirements which need to
+ * be handled by software, this function shall check for the precise
+ * requirement of the transformation and put any software fallbacks
+ * in place.
+ * @cra_exit: Deinitialize the cryptographic transformation object. This is a
+ * counterpart to @cra_init, used to remove various changes set in
+ * @cra_init.
+ * @cra_module: Owner of this transformation implementation. Set to THIS_MODULE
+ * @cra_list: internally used
+ * @cra_users: internally used
+ * @cra_refcnt: internally used
+ * @cra_destroy: internally used

+ * DOC: Asynchronous Block Cipher API
+ *
+ * Asynchronous block cipher API is used with the ciphers of type
+ * CRYPTO_ALG_TYPE_ABLKCIPHER (listed as type "ablkcipher" in /proc/crypto).
+ *
+ * Asynchronous cipher operations imply that the function invocation for a
+ * cipher request returns immediately before the completion of the operation.
+ * The cipher request is scheduled as a separate kernel thread and therefore
+ * load-balanced on the different CPUs via the process scheduler. To allow
+ * the kernel crypto API to inform the caller about the completion of a cipher
+ * request, the caller must provide a callback function. That function is
+ * invoked with the cipher handle when the request completes.
+ *
+ * To support the asynchronous operation, additional information than just the
+ * cipher handle must be supplied to the kernel crypto API. That additional
+ * information is given by filling in the ablkcipher_request data structure.
+ *
+ * For the asynchronous block cipher API, the state is maintained with the tfm
+ * cipher handle. A single tfm can be used across multiple calls and in
+ * parallel. For asynchronous block cipher calls, context data supplied and
+ * only used by the caller can be referenced the request data structure in
+ * addition to the IV used for the cipher request. The maintenance of such
+ * state information would be important for a crypto driver implementer to
+ * have, because when calling the callback function upon completion of the
+ * cipher operation, that callback function may need some information about
+ * which operation just finished if it invoked multiple in parallel. This
+ * state information is unused by the kernel crypto API.

+ * struct bus_type - The bus type of the device
+ *
+ * @name: The name of the bus.

+ * @dev_root: Default device to use as the parent.
+ * @dev_attrs: Default attributes of the devices on the bus.
+ * @bus_groups: Default attributes of the bus.
+ * @dev_groups: Default attributes of the devices on the bus.
+ * @drv_groups: Default attributes of the device drivers on the bus.
+ * @match: Called, perhaps multiple times, whenever a new device or driver
+ * is added for this bus. It should return a nonzero value if the
+ * given device can be handled by the given driver.
+ * @uevent: Called when a device is added, removed, or a few other things
+ * that generate uevents to add the environment variables.
+ * @probe: Called when a new device or driver add to this bus, and callback
+ * the specific driver's probe to initial the matched device.
+ * @remove: Called when a device removed from this bus.
+ * @shutdown: Called at shut-down time to quiesce the device.
+ *
+ * @online: Called to put the device back online (after offlining it).
+ * @offline: Called to put the device offline for hot-removal. May fail.
+ *
+ * @suspend: Called when a device on this bus wants to go to sleep mode.
+ * @resume: Called to bring a device on this bus out of sleep mode.
+ * @pm: Power management operations of this bus, callback the specific
+ * device driver's pm-ops.
+ * @iommu_ops: IOMMU specific operations for this bus, used to attach IOMMU
+ * driver implementations to a bus and allow the driver to do
+ * bus-specific setup
+ * @p: The private data of the driver core, only the driver core can
+ * touch this.
+ * @lock_key: Lock class key for use by the lock validator
+ *
+ * A bus is a channel between the processor and one or more devices. For the
+ * purposes of the device model, all devices are connected via a bus, even if
+ * it is an internal, virtual, "platform" bus. Buses can plug into each other.
+ * A USB controller is usually a PCI device, for example. The device model
+ * represents the actual connections between buses and the devices they control.
+ * A bus is represented by the bus_type structure. It contains the name, the
+ * default attributes, the bus' methods, PM operations, and the driver core's
+ * private data.

+/**
+ * struct device - The basic device structure
+ * @parent: The device's "parent" device, the device to which it is attached.
+ * In most cases, a parent device is some sort of bus or host
+ * controller. If parent is NULL, the device, is a top-level device,
+ * which is not usually what you want.
+ * @p: Holds the private data of the driver core portions of the device.
+ * See the comment of the struct device_private for detail.
+ * @kobj: A top-level, abstract class from which other classes are derived.
+ * @init_name: Initial name of the device.
+ * @type: The type of device.
+ * This identifies the device type and carries type-specific
+ * information.
+ * @mutex: Mutex to synchronize calls to its driver.
+ * @bus: Type of bus device is on.
+ * @driver: Which driver has allocated this
+ * @platform_data: Platform data specific to the device.
+ * Example: For devices on custom boards, as typical of embedded
+ * and SOC based hardware, Linux often uses platform_data to point
+ * to board-specific structures describing devices and how they
+ * are wired. That can include what ports are available, chip
+ * variants, which GPIO pins act in what additional roles, and so
+ * on. This shrinks the "Board Support Packages" (BSPs) and
+ * minimizes board-specific #ifdefs in drivers.
+ * @driver_data: Private pointer for driver specific info.
+ * @power: For device power management.
+ * See Documentation/power/devices.txt for details.
+ * @pm_domain: Provide callbacks that are executed during system suspend,
+ * hibernation, system resume and during runtime PM transitions
+ * along with subsystem-level and driver-level callbacks.
+ * @pins: For device pin management.
+ * See Documentation/pinctrl.txt for details.
+ * @numa_node: NUMA node this device is close to.
+ * @dma_mask: Dma mask (if dma'ble device).
+ * @coherent_dma_mask: Like dma_mask, but for alloc_coherent mapping as not all
+ * hardware supports 64-bit addresses for consistent allocations
+ * such descriptors.
+ * @dma_pfn_offset: offset of DMA memory range relatively of RAM
+ * @dma_parms: A low level driver may set these to teach IOMMU code about
+ * segment limitations.
+ * @dma_pools: Dma pools (if dma'ble device).
+ * @dma_mem: Internal for coherent mem override.
+ * @cma_area: Contiguous memory area for dma allocations
+ * @archdata: For arch-specific additions.
+ * @of_node: Associated device tree node.
+ * @fwnode: Associated device node supplied by platform firmware.
+ * @devt: For creating the sysfs "dev".
+ * @id: device instance
+ * @devres_lock: Spinlock to protect the resource of the device.
+ * @devres_head: The resources list of the device.
+ * @knode_class: The node used to add the device to the class list.
+ * @class: The class of the device.
+ * @groups: Optional attribute groups.
+ * @release: Callback to free the device after all references have
+ * gone away. This should be set by the allocator of the
+ * device (i.e. the bus driver that discovered the device).
+ * @iommu_group: IOMMU group the device belongs to.
+ *
+ * @offline_disabled: If set, the device is permanently online.
+ * @offline: Set after successful invocation of bus type's .offline().
+ *
+ * At the lowest level, every device in a Linux system is represented by an
+ * instance of struct device. The device structure contains the information
+ * that the device model core needs to model the system. Most subsystems,
+ * however, track additional information about the devices they host. As a
+ * result, it is rare for devices to be represented by bare device structures;
+ * instead, that structure, like kobject structures, is usually embedded within
+ * a higher-level representation of the device.

+ * Contiguous Memory Allocator
+ *
+ * The Contiguous Memory Allocator (CMA) makes it possible to
+ * allocate big contiguous chunks of memory after the system has
+ * booted.
+ *
+ * Why is it needed?
+ *
+ * Various devices on embedded systems have no scatter-getter and/or
+ * IO map support and require contiguous blocks of memory to
+ * operate. They include devices such as cameras, hardware video
+ * coders, etc.
+ *
+ * Such devices often require big memory buffers (a full HD frame
+ * is, for instance, more then 2 mega pixels large, i.e. more than 6
+ * MB of memory), which makes mechanisms such as kmalloc() or
+ * alloc_page() ineffective.
+ *
+ * At the same time, a solution where a big memory region is
+ * reserved for a device is suboptimal since often more memory is
+ * reserved then strictly required and, moreover, the memory is
+ * inaccessible to page system even if device drivers don't use it.
+ *
+ * CMA tries to solve this issue by operating on memory regions
+ * where only movable pages can be allocated from. This way, kernel
+ * can use the memory for pagecache and when device driver requests
+ * it, allocated pages can be migrated.
+ *
+ * Driver usage
+ *
+ * CMA should not be used by the device drivers directly. It is
+ * only a helper framework for dma-mapping subsystem.
+ *
+ * For more information, see kernel-docs in drivers/base/dma-contiguous.c

+ * Dynamic queue limits (dql) - Definitions
+ *
+ * Copyright (c) 2011, Tom Herbert <therbert@google.com>
+ *
+ * This header file contains the definitions for dynamic queue limits (dql).
+ * dql would be used in conjunction with a producer/consumer type queue
+ * (possibly a HW queue). Such a queue would have these general properties:
+ *
+ * 1) Objects are queued up to some limit specified as number of objects.
+ * 2) Periodically a completion process executes which retires consumed
+ * objects.
+ * 3) Starvation occurs when limit has been reached, all queued data has
+ * actually been consumed, but completion processing has not yet run
+ * so queuing new data is blocked.
+ * 4) Minimizing the amount of queued data is desirable.
+ *
+ * The goal of dql is to calculate the limit as the minimum number of objects
+ * needed to prevent starvation.
+ *
+ * The primary functions of dql are:
+ * dql_queued - called when objects are enqueued to record number of objects
+ * dql_avail - returns how many objects are available to be queued based
+ * on the object limit and how many objects are already enqueued
+ * dql_completed - called at completion time to indicate how many objects
+ * were retired from the queue
+ *
+ * The dql implementation does not implement any locking for the dql data
+ * structures, the higher layer should provide this. dql_queued should
+ * be serialized to prevent concurrent execution of the function; this
+ * is also true for dql_completed. However, dql_queued and dlq_completed can
+ * be executed concurrently (i.e. they can be protected by different locks).

+ * Concepts used at the EDAC subsystem
+ *
+ * There are several things to be aware of that aren't at all obvious:
+ *
+ * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
+ *
+ * These are some of the many terms that are thrown about that don't always
+ * mean what people think they mean (Inconceivable!). In the interest of
+ * creating a common ground for discussion, terms and their definitions
+ * will be established.
+ *
+ * Memory devices: The individual DRAM chips on a memory stick. These
+ * devices commonly output 4 and 8 bits each (x4, x8).
+ * Grouping several of these in parallel provides the
+ * number of bits that the memory controller expects:
+ * typically 72 bits, in order to provide 64 bits +
+ * 8 bits of ECC data.
+ *
+ * Memory Stick: A printed circuit board that aggregates multiple
+ * memory devices in parallel. In general, this is the
+ * Field Replaceable Unit (FRU) which gets replaced, in
+ * the case of excessive errors. Most often it is also
+ * called DIMM (Dual Inline Memory Module).
+ *
+ * Memory Socket: A physical connector on the motherboard that accepts
+ * a single memory stick. Also called as "slot" on several
+ * datasheets.
+ *
+ * Channel: A memory controller channel, responsible to communicate
+ * with a group of DIMMs. Each channel has its own
+ * independent control (command) and data bus, and can
+ * be used independently or grouped with other channels.
+ *
+ * Branch: It is typically the highest hierarchy on a
+ * Fully-Buffered DIMM memory controller.
+ * Typically, it contains two channels.
+ * Two channels at the same branch can be used in single
+ * mode or in lockstep mode.
+ * When lockstep is enabled, the cacheline is doubled,
+ * but it generally brings some performance penalty.
+ * Also, it is generally not possible to point to just one
+ * memory stick when an error occurs, as the error
+ * correction code is calculated using two DIMMs instead
+ * of one. Due to that, it is capable of correcting more
+ * errors than on single mode.
+ *
+ * Single-channel: The data accessed by the memory controller is contained
+ * into one dimm only. E. g. if the data is 64 bits-wide,
+ * the data flows to the CPU using one 64 bits parallel
+ * access.
+ * Typically used with SDR, DDR, DDR2 and DDR3 memories.
+ * FB-DIMM and RAMBUS use a different concept for channel,
+ * so this concept doesn't apply there.
+ *
+ * Double-channel: The data size accessed by the memory controller is
+ * interlaced into two dimms, accessed at the same time.
+ * E. g. if the DIMM is 64 bits-wide (72 bits with ECC),
+ * the data flows to the CPU using a 128 bits parallel
+ * access.
+ *
+ * Chip-select row: This is the name of the DRAM signal used to select the
+ * DRAM ranks to be accessed. Common chip-select rows for
+ * single channel are 64 bits, for dual channel 128 bits.
+ * It may not be visible by the memory controller, as some
+ * DIMM types have a memory buffer that can hide direct
+ * access to it from the Memory Controller.
+ *
+ * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memory.
+ * Motherboards commonly drive two chip-select pins to
+ * a memory stick. A single-ranked stick, will occupy
+ * only one of those rows. The other will be unused.
+ *
+ * Double-Ranked stick: A double-ranked stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently.
+ *
+ * Double-sided stick: DEPRECATED TERM, see Double-Ranked stick.
+ * A double-sided stick has two chip-select rows which
+ * access different sets of memory devices. The two
+ * rows cannot be accessed concurrently. "Double-sided"
+ * is irrespective of the memory devices being mounted
+ * on both sides of the memory stick.
+ *
+ * Socket set: All of the memory sticks that are required for
+ * a single memory access or all of the memory sticks
+ * spanned by a chip-select row. A single socket set
+ * has two chip-select rows and if double-sided sticks
+ * are used these will occupy those chip-select rows.
+ *
+ * Bank: This term is avoided because it is unclear when
+ * needing to distinguish between chip-select rows and
+ * socket sets.

+ * @encode_fh: encode a file handle fragment from a dentry
+ * @fh_to_dentry: find the implied object and get a dentry for it

+ * @get_name: find the name for a given inode in a given directory
+ * @get_parent: find the parent of a given directory
+ * @commit_metadata: commit metadata changes to stable storage
+ *
+ * See Documentation/filesystems/nfs/Exporting for details on how to use
+ * this interface correctly.
+ *
+ * encode_fh:
+ * @encode_fh should store in the file handle fragment @fh (using at most
+ * @max_len bytes) information that can be used by @decode_fh to recover the
+ * file referred to by the &struct dentry @de. If the @connectable flag is
+ * set, the encode_fh() should store sufficient information so that a good
+ * attempt can be made to find not only the file but also it's place in the
+ * filesystem. This typically means storing a reference to de->d_parent in
+ * the filehandle fragment. encode_fh() should return the fileid_type on
+ * success and on error returns 255 (if the space needed to encode fh is
+ * greater than @max_len*4 bytes). On error @max_len contains the minimum
+ * size(in 4 byte unit) needed to encode the file handle.
+ *
+ * fh_to_dentry:
+ * @fh_to_dentry is given a &struct super_block (@sb) and a file handle
+ * fragment (@fh, @fh_len). It should return a &struct dentry which refers
+ * to the same file that the file handle fragment refers to. If it cannot,
+ * it should return a %NULL pointer if the file was found but no acceptable
+ * &dentries were available, or an %ERR_PTR error code indicating why it
+ * couldn't be found (e.g. %ENOENT or %ENOMEM). Any suitable dentry can be
+ * returned including, if necessary, a new dentry created with d_alloc_root.
+ * The caller can then find any other extant dentries by following the
+ * d_alias links.
+ *
+ * fh_to_parent:
+ * Same as @fh_to_dentry, except that it returns a pointer to the parent
+ * dentry if it was encoded into the filehandle fragment by @encode_fh.
+ *
+ * get_name:
+ * @get_name should find a name for the given @child in the given @parent
+ * directory. The name should be stored in the @name (with the
+ * understanding that it is already pointing to a a %NAME_MAX+1 sized
+ * buffer. get_name() should return %0 on success, a negative error code
+ * or error. @get_name will be called without @parent->i_mutex held.
+ *
+ * get_parent:
+ * @get_parent should find the parent directory for the given @child which
+ * is also a directory. In the event that it cannot be found, or storage
+ * space cannot be allocated, a %ERR_PTR should be returned.
+ *
+ * commit_metadata:
+ * @commit_metadata should commit metadata changes to stable storage.
+ *
+ * Locking rules:
+ * get_parent is called with child->d_inode->i_mutex down
+ * get_name is not (which is possibly inconsistent)

+ * Notes on enable_signaling:
+ * For fence implementations that have the capability for hw->hw

+ * irqs, or insert commands into cmdstream, etc. This is called
+ * in the first wait() or add_callback() path to let the fence
+ * implementation know that there is another driver waiting on
+ * the signal (ie. hw->sw case).
+ *
+ * This function can be called called from atomic context, but not
+ * from irq context, so normal spinlocks can be used.
+ *
+ * A return value of false indicates the fence already passed,
+ * or some failure occurred that made it impossible to enable
+ * signaling. True indicates successful enabling.
+ *
+ * fence->status may be set in enable_signaling, but only when false is
+ * returned.
+ *
+ * Calling fence_signal before enable_signaling is called allows
+ * for a tiny race window in which enable_signaling is called during,
+ * before, or after fence_signal. To fight this, it is recommended
+ * that before enable_signaling returns true an extra reference is
+ * taken on the fence, to be released when the fence is signaled.
+ * This will mean fence_signal will still be called twice, but
+ * the second time will be a noop since it was already signaled.
+ *
+ * Notes on signaled:
+ * May set fence->status if returning true.
+ *
+ * Notes on wait:
+ * Must not be NULL, set to fence_default_wait for default implementation.
+ * the fence_default_wait implementation should work for any fence, as long
+ * as enable_signaling works correctly.
+ *
+ * Must return -ERESTARTSYS if the wait is intr = true and the wait was
+ * interrupted, and remaining jiffies if fence has signaled, or 0 if wait
+ * timed out. Can also return other error values on custom implementations,
+ * which should be treated as if the fence is signaled. For example a hardware
+ * lockup could be reported like that.
+ *
+ * Notes on release:
+ * Can be NULL, this function allows additional commands to run on
+ * destruction of the fence. Can be called from irq context.
+ * If pointer is set to NULL, kfree will get called instead.

+ * The below are the various read and write types that we support. Some of

+ *
+ * The block layer uses device plugging to defer IO a little bit, in
+ * the hope that we will see more IO very shortly. This increases
+ * coalescing of adjacent IO and thus reduces the number of IOs we
+ * have to send to the device. It also allows for better queuing,
+ * if the IO isn't mergeable. If the caller is going to be waiting
+ * for the IO, then he must ensure that the device is unplugged so
+ * that the IO is dispatched to the driver.
+ *
+ * All IO is handled async in Linux. This is fine for background
+ * writes, but for reads or writes that someone waits for completion
+ * on, we want to notify the block layer and IO scheduler so that they
+ * know about it. That allows them to make better scheduling
+ * decisions. So when the below references 'sync' and 'async', it
+ * is referencing this priority hint.
+ *
+ * With that in mind, the available types are:
+ *
+ * READ A normal read operation. Device will be plugged.
+ * READ_SYNC A synchronous read. Device is not plugged, caller can
+ * immediately wait on this read without caring about
+ * unplugging.
+ * READA Used for read-ahead operations. Lower priority, and the
+ * block layer could (in theory) choose to ignore this
+ * request if it runs into resource problems.
+ * WRITE A normal async write. Device will be plugged.
+ * WRITE_SYNC Synchronous write. Identical to WRITE, but passes down
+ * the hint that someone will be waiting on this IO
+ * shortly. The write equivalent of READ_SYNC.
+ * WRITE_ODIRECT Special case write for O_DIRECT only.
+ * WRITE_FLUSH Like WRITE_SYNC but with preceding cache flush.
+ * WRITE_FUA Like WRITE_SYNC but data is guaranteed to be on
+ * non-volatile media on completion.
+ * WRITE_FLUSH_FUA Combination of WRITE_FLUSH and FUA. The IO is preceded
+ * by a cache flush and data is guaranteed to be on
+ * non-volatile media on completion.

+ * Inode state bits. Protected by inode->i_lock
+ *
+ * Three bits determine the dirty state of the inode, I_DIRTY_SYNC,
+ * I_DIRTY_DATASYNC and I_DIRTY_PAGES.
+ *
+ * Four bits define the lifetime of an inode. Initially, inodes are I_NEW,
+ * until that flag is cleared. I_WILL_FREE, I_FREEING and I_CLEAR are set at
+ * various stages of removing an inode.
+ *
+ * Two bits are used for locking and completion notification, I_NEW and I_SYNC.
+ *
+ * I_DIRTY_SYNC Inode is dirty, but doesn't have to be written on
+ * fdatasync(). i_atime is the usual cause.
+ * I_DIRTY_DATASYNC Data-related inode changes pending. We keep track of
+ * these changes separately from I_DIRTY_SYNC so that we
+ * don't have to write inode on fdatasync() when only
+ * mtime has changed in it.
+ * I_DIRTY_PAGES Inode has dirty pages. Inode itself may be clean.
+ * I_NEW Serves as both a mutex and completion notification.
+ * New inodes set I_NEW. If two processes both create
+ * the same inode, one of them will release its inode and
+ * wait for I_NEW to be released before returning.
+ * Inodes in I_WILL_FREE, I_FREEING or I_CLEAR state can
+ * also cause waiting on I_NEW, without I_NEW actually
+ * being set. find_inode() uses this to prevent returning
+ * nearly-dead inodes.
+ * I_WILL_FREE Must be set when calling write_inode_now() if i_count
+ * is zero. I_FREEING must be set when I_WILL_FREE is
+ * cleared.
+ * I_FREEING Set when inode is about to be freed but still has dirty
+ * pages or buffers attached or the inode itself is still
+ * dirty.
+ * I_CLEAR Added by clear_inode(). In this state the inode is
+ * clean and can be destroyed. Inode keeps I_FREEING.
+ *
+ * Inodes that are I_WILL_FREE, I_FREEING or I_CLEAR are
+ * prohibited for many purposes. iget() must wait for
+ * the inode to be completely released, then create it
+ * anew. Other functions will just ignore such inodes,
+ * if appropriate. I_NEW is used for waiting.
+ *
+ * I_SYNC Writeback of inode is running. The bit is set during
+ * data writeback, and cleared with a wakeup on the bit
+ * address once it is done. The bit is also used to pin
+ * the inode in memory for flusher thread.
+ *
+ * I_REFERENCED Marks the inode as recently references on the LRU list.
+ *
+ * I_DIO_WAKEUP Never set. Only used as a key for wait_on_bit().
+ *
+ * Q: What is the difference between I_WILL_FREE and I_FREEING?

+ * Basic general purpose allocator for managing special purpose

+ * memory, uncached memory etc.
+ *
+ * It is safe to use the allocator in NMI handlers and other special
+ * unblockable contexts that could otherwise deadlock on locks. This
+ * is implemented by using atomic operations and retries on any
+ * conflicts. The disadvantage is that there may be livelocks in
+ * extreme cases. For better scalability, one allocator can be used
+ * for each CPU.
+ *
+ * The lockless operation only works if there is enough memory
+ * available. If new memory is added to the pool a lock has to be
+ * still taken. So any user relying on locklessness has to ensure
+ * that sufficient memory is preallocated.
+ *
+ * The basic atomic operation of this allocator is cmpxchg on long.
+ * On architectures that don't have NMI-safe cmpxchg implementation,
+ * the allocator can NOT be used in NMI handler. So code uses the
+ * allocator in NMI handler should depend on
+ * CONFIG_ARCH_HAVE_NMI_SAFE_CMPXCHG.

+ * struct gpio_chip - abstract a GPIO controller
+ * @label: for diagnostics
+ * @dev: optional device providing the GPIOs
+ * @owner: helps prevent removal of modules exporting active GPIOs
+ * @list: links gpio_chips together for traversal
+ * @request: optional hook for chip-specific activation, such as
+ * enabling module power and clock; may sleep
+ * @free: optional hook for chip-specific deactivation, such as
+ * disabling module power and clock; may sleep
+ * @get_direction: returns direction for signal "offset", 0=out, 1=in,
+ * (same as GPIOF_DIR_XXX), or negative error
+ * @direction_input: configures signal "offset" as input, or returns error
+ * @direction_output: configures signal "offset" as output, or returns error
+ * @get: returns value for signal "offset"; for output signals this
+ * returns either the value actually sensed, or zero
+ * @set: assigns output value for signal "offset"
+ * @set_multiple: assigns output values for multiple signals defined by "mask"
+ * @set_debounce: optional hook for setting debounce time for specified gpio in
+ * interrupt triggered gpio chips
+ * @to_irq: optional hook supporting non-static gpio_to_irq() mappings;
+ * implementation may not sleep
+ * @dbg_show: optional routine to show contents in debugfs; default code
+ * will be used when this is omitted, but custom code can show extra
+ * state (such as pullup/pulldown configuration).
+ * @base: identifies the first GPIO number handled by this chip; or, if
+ * negative during registration, requests dynamic ID allocation.
+ * @ngpio: the number of GPIOs handled by this controller; the last GPIO
+ * handled is (base + ngpio - 1).
+ * @desc: array of ngpio descriptors. Private.
+ * @names: if set, must be an array of strings to use as alternative
+ * names for the GPIOs in this chip. Any entry in the array
+ * may be NULL if there is no alias for the GPIO, however the
+ * array must be @ngpio entries long. A name can include a single printk
+ * format specifier for an unsigned int. It is substituted by the actual
+ * number of the gpio.
+ * @can_sleep: flag must be set iff get()/set() methods sleep, as they
+ * must while accessing GPIO expander chips over I2C or SPI. This
+ * implies that if the chip supports IRQs, these IRQs need to be threaded
+ * as the chip access may sleep when e.g. reading out the IRQ status
+ * registers.
+ * @exported: flags if the gpiochip is exported for use from sysfs. Private.
+ * @irq_not_threaded: flag must be set if @can_sleep is set but the
+ * IRQs don't need to be threaded
+ *
+ * A gpio_chip can help platforms abstract various sources of GPIOs so
+ * they can all be accessed through a common programing interface.
+ * Example sources would be SOC controllers, FPGAs, multifunction
+ * chips, dedicated GPIO expanders, and so on.
+ *
+ * Each chip controls a number of signals, identified in method calls
+ * by "offset" values in the range 0..(@ngpio - 1). When those signals
+ * are referenced through calls like gpio_get_value(gpio), the offset
+ * is calculated by subtracting @base from the gpio number.

+ * output-only GPO pin will be added at the end of the block.
+ * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
+ * for each IO line in the expander. Setting the bit at
+ * position n will enable the pull-up for the IO at
+ * the corresponding offset. For chips with fewer than
+ * 16 IO pins, high-end bits are ignored.
+ * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down

+ * operation for each IO line in the expander. Setting the
+ * bit at position n enables open-drain operation for
+ * the IO at the corresponding offset. Clearing the bit
+ * enables regular push-pull operation for that IO.
+ * For chips with fewer than 16 IO pins, high-end bits
+ * are ignored.
+ * @io_polarity: A bit-mask which enables polarity inversion for each IO line
+ * in the expander. Setting the bit at position n inverts
+ * the polarity of that IO line, while clearing it results
+ * in normal polarity. For chips with fewer than 16 IO pins,
+ * high-end bits are ignored.
+ * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
+ * is connected, via which it reports interrupt events
+ * across all GPIO lines. This must be a real,
+ * pre-existing IRQ line.
+ * Setting this value < 0 disables the irq_chip functionality
+ * of the driver.
+ * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
+ * IRQ lines will appear. Similarly to gpio_base, the expander
+ * will create a block of irqs beginning at this number.
+ * This value is ignored if irq_summary is < 0.
+ * @reset_during_probe: If set to true, the driver will trigger a full
+ * reset of the chip at the beginning of the probe

+ * action (turn on a LED, play sound, etc.) The call is protected
+ * by @event_lock and must not sleep
+ * @grab: input handle that currently has the device grabbed (via
+ * EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
+ * recipient for all input events coming from the device
+ * @event_lock: this spinlock is is taken when input core receives
+ * and processes a new event for the device (in input_event()).
+ * Code that accesses and/or modifies parameters of a device
+ * (such as keymap or absmin, absmax, absfuzz, etc.) after device
+ * has been registered with input core must take this lock.
+ * @mutex: serializes calls to open(), close() and flush() methods
+ * @users: stores number of users (input handlers) that opened this
+ * device. It is used by input_open_device() and input_close_device()
+ * to make sure that dev->open() is only called when the first
+ * user opens device and dev->close() is called when the very

+ * An io_cq (icq) is association between an io_context (ioc) and a

+ * information per ioc - q pair.
+ *
+ * Elevator can request use of icq by setting elevator_type->icq_size and
+ * ->icq_align. Both size and align must be larger than that of struct
+ * io_cq and elevator can use the tail area for private information. The
+ * recommended way to do this is defining a struct which contains io_cq as
+ * the first member followed by private members and using its size and
+ * align. For example,
+ *
+ * struct snail_io_cq {
+ * struct io_cq icq;
+ * int poke_snail;
+ * int feed_snail;
+ * };
+ *
+ * struct elevator_type snail_elv_type {
+ * .ops = { ... },
+ * .icq_size = sizeof(struct snail_io_cq),
+ * .icq_align = __alignof__(struct snail_io_cq),
+ * ...
+ * };
+ *
+ * If icq_size is set, block core will manage icq's. All requests will
+ * have its ->elv.icq field set before elevator_ops->elevator_set_req_fn()
+ * is called and be holding a reference to the associated io_context.
+ *
+ * Whenever a new icq is created, elevator_ops->elevator_init_icq_fn() is
+ * called and, on destruction, ->elevator_exit_icq_fn(). Both functions
+ * are called with both the associated io_context and queue locks held.
+ *
+ * Elevator is allowed to lookup icq using ioc_lookup_icq() while holding
+ * queue lock but the returned icq is valid only until the queue lock is
+ * released. Elevators can not and should not try to create or destroy
+ * icq's.
+ *
+ * As icq's are linked from both ioc and q, the locking rules are a bit
+ * complex.
+ *
+ * - ioc lock nests inside q lock.
+ *
+ * - ioc->icq_list and icq->ioc_node are protected by ioc lock.
+ * q->icq_list and icq->q_node by q lock.
+ *
+ * - ioc->icq_tree and ioc->icq_hint are protected by ioc lock, while icq
+ * itself is protected by q lock. However, both the indexes and icq
+ * itself are also RCU managed and lookup can be performed holding only
+ * the q lock.
+ *
+ * - icq's are not reference counted. They are destroyed when either the
+ * ioc or q goes away. Each request with icq set holds an extra
+ * reference to ioc to ensure it stays until the request is completed.
+ *
+ * - Linking and unlinking icq's are performed while holding both ioc and q
+ * locks. Due to the lock ordering, q exit is simple but ioc exit

+ * irq_domain - IRQ translation domains
+ *
+ * Translation infrastructure between hw and linux irq numbers. This is
+ * helpful for interrupt controllers to implement mapping between hardware
+ * irq numbers and the Linux irq number space.
+ *
+ * irq_domains also have a hook for translating device tree interrupt
+ * representation into a hardware irq number that can be mapped back to a
+ * Linux irq number without any extra platform support code.
+ *
+ * Interrupt controller "domain" data structure. This could be defined as a
+ * irq domain controller. That is, it handles the mapping between hardware
+ * and virtual interrupt numbers for a given interrupt domain. The domain
+ * structure is generally created by the PIC code for a given PIC instance
+ * (though a domain can cover more than one PIC if they have a flat number
+ * model). It's the domain callbacks that are responsible for setting the
+ * irq_chip on a given irq_desc after it's been mapped.
+ *
+ * The host code and data structures are agnostic to whether or not
+ * we use an open firmware device-tree. We do have references to struct
+ * device_node in two places: in irq_find_host() to find the host matching
+ * a given interrupt controller node, and of course as an argument to its
+ * counterpart domain->ops->match() callback. However, those are treated as
+ * generic pointers by the core and the fact that it's actually a device-node
+ * pointer is purely a convention between callers and implementation. This
+ * code could thus be used on other architectures by replacing those two
+ * by some sort of arch-specific void * "token" used to identify interrupt
+ * controllers.

+/* enough time to check whether ist should be accepted. */
+/* The PROT_IO Command extends the interface to make protocol dependent */
+/* features available (call diversion, call waiting...). */
+/* */
+/* The PROT_IO Command is executed with the desired driver id and the arg */
+/* parameter coded as follows: */
+/* The lower 8 bits of arg contain the desired protocol from ISDN_PTYPE */
+/* definitions. The upper 24 bits represent the protocol specific cmd/stat.*/
+/* Any additional data is protocol and command specific. */
+/* This mechanism also applies to the statcallb callback STAT_PROT. */
+/* */
+/* This suggested extension permits an easy expansion of protocol specific */
+/* handling. Extensions may be added at any time without changing the HL */
+/* driver code and not getting conflicts without certifications. */
+/* The well known CAPI 2.0 interface handles such extensions in a similar */
+/* way. Perhaps a protocol specific module may be added and separately */
+/* loaded and linked to the basic isdn module for handling. */

+ * is a constant and is in nanoseconds. We will use scaled math
+ * with a set of scales defined here as SEC_JIFFIE_SC, USEC_JIFFIE_SC and
+ * NSEC_JIFFIE_SC. Note that these defines contain nothing but
+ * constants and so are computed at compile time. SHIFT_HZ (computed in
+ * timex.h) adjusts the scaling for different HZ values.
+
+ * Scaled math??? What is that?
+ *
+ * Scaled math is a way to do integer math on values that would,
+ * otherwise, either overflow, underflow, or cause undesired div
+ * instructions to appear in the execution path. In short, we "scale"
+ * up the operands so they take more bits (more precision, less
+ * underflow), do the desired operation and then "scale" the result back
+ * by the same amount. If we do the scaling by shifting we avoid the
+ * costly mpy and the dastardly div instructions.
+
+ * Suppose, for example, we want to convert from seconds to jiffies
+ * where jiffies is defined in nanoseconds as NSEC_PER_JIFFIE. The
+ * simple math is: jiff = (sec * NSEC_PER_SEC) / NSEC_PER_JIFFIE; We
+ * observe that (NSEC_PER_SEC / NSEC_PER_JIFFIE) is a constant which we
+ * might calculate at compile time, however, the result will only have
+ * about 3-4 bits of precision (less for smaller values of HZ).
+ *
+ * So, we scale as follows:
+ * jiff = (sec) * (NSEC_PER_SEC / NSEC_PER_JIFFIE);
+ * jiff = ((sec) * ((NSEC_PER_SEC * SCALE)/ NSEC_PER_JIFFIE)) / SCALE;
+ * Then we make SCALE a power of two so:
+ * jiff = ((sec) * ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE)) >> SCALE;
+ * Now we define:
+ * #define SEC_CONV = ((NSEC_PER_SEC << SCALE)/ NSEC_PER_JIFFIE))
+ * jiff = (sec * SEC_CONV) >> SCALE;
+ *
+ * Often the math we use will expand beyond 32-bits so we tell C how to
+ * do this and pass the 64-bit result of the mpy through the ">> SCALE"
+ * which should take the result back to 32-bits. We want this expansion
+ * to capture as much precision as possible. At the same time we don't
+ * want to overflow so we pick the SCALE to avoid this. In this file,
+ * that means using a different scale for each range of HZ values (as
+ * defined in timex.h).
+ *
+ * For those who want to know, gcc will give a 64-bit result from a "*"
+ * operator if the result is a long long AND at least one of the
+ * operands is cast to long long (usually just prior to the "*" so as
+ * not to confuse it into thinking it really has a 64-bit operand,
+ * which, buy the way, it can do, but it takes more code and at least 2
+ * mpys).
+
+ * We also need to be aware that one second in nanoseconds is only a
+ * couple of bits away from overflowing a 32-bit word, so we MUST use
+ * 64-bits to get the full range time in nanoseconds.
+
+ */
+
+/*
+ * Here are the scales we will use. One for seconds, nanoseconds and
+ * microseconds.
+ *
+ * Within the limits of cpp we do a rough cut at the SEC_JIFFIE_SC and
+ * check if the sign bit is set. If not, we bump the shift count by 1.
+ * (Gets an extra bit of precision where we can use it.)
+ * We know it is set for HZ = 1024 and HZ = 100 not for 1000.

+ * Jump labels provide an interface to generate dynamic branches using
+ * self-modifying code. Assuming toolchain and architecture support, the result
+ * of a "if (static_key_false(&key))" statement is an unconditional branch (which
+ * defaults to false - and the true block is placed out of line).
+ *
+ * However at runtime we can change the branch target using
+ * static_key_slow_{inc,dec}(). These function as a 'reference' count on the key
+ * object, and for as long as there are references all branches referring to
+ * that particular key will point to the (out of line) true block.
+ *
+ * Since this relies on modifying code, the static_key_slow_{inc,dec}() functions
+ * must be considered absolute slow paths (machine wide synchronization etc.).
+ * OTOH, since the affected branches are unconditional, their runtime overhead
+ * will be absolutely minimal, esp. in the default (off) case where the total
+ * effect is a single NOP of appropriate size. The on case will patch in a jump
+ * to the out-of-line block.
+ *
+ * When the control is directly exposed to userspace, it is prudent to delay the
+ * decrement to avoid high frequency code modifications which can (and do)
+ * cause significant performance degradation. Struct static_key_deferred and
+ * static_key_slow_dec_deferred() provide for this.
+ *
+ * Lacking toolchain and or architecture support, jump labels fall back to a simple
+ * conditional branch.
+ *
+ * struct static_key my_key = STATIC_KEY_INIT_TRUE;
+ *
+ * if (static_key_true(&my_key)) {
+ * }

+ * reference. Mixing static_key_true() and static_key_false() on the same key is not
+ * allowed.
+ *
+ * Not initializing the key (static data is initialized to 0s anyway) is the

+ * llist_del_first can not be used here. Because llist_del_first

+ * If there are multiple producers and one consumer, llist_add can be

+ * in the consumer.
+ *
+ * This can be summarized as follow:
+ *
+ * | add | del_first | del_all
+ * add | - | - | -
+ * del_first | | L | L
+ * del_all | | | -
+ *
+ * Where "-" stands for no lock is needed, while "L" stands for lock
+ * is needed.
+ *
+ * The list entries deleted via llist_del_all can be traversed with
+ * traversing function such as llist_for_each etc. But the list
+ * entries can not be traversed safely before deleted from the list.
+ * The order of deleted entries is from the newest to the oldest added
+ * one. If you want to traverse from the oldest to the newest, you
+ * must reverse the order by yourself before traversing.
+ *
+ * The basic atomic operation of this list is cmpxchg on long. On
+ * architectures that don't have NMI-safe cmpxchg implementation, the
+ * list can NOT be used in NMI handlers. So code that uses the list in
+ * an NMI handler should depend on CONFIG_ARCH_HAVE_NMI_SAFE_CMPXCHG.

+This header file (and its .c file; kernel-doc of functions see there)
+ define a helper framework to easily keep track of index:label associations,
+ and changes to an "active set" of objects, as well as pending transactions,
+ to persistently record those changes.
+
+ We use an LRU policy if it is necessary to "cool down" a region currently in
+ the active set before we can "heat" a previously unused region.
+
+ Because of this later property, it is called "lru_cache".
+ As it actually Tracks Objects in an Active SeT, we could also call it
+ toast (incidentally that is what may happen to the data on the
+ backend storage uppon next resync, if we don't get it right).
+
+What for?
+
+We replicate IO (more or less synchronously) to local and remote disk.
+
+For crash recovery after replication node failure,
+ we need to resync all regions that have been target of in-flight WRITE IO
+ (in use, or "hot", regions), as we don't know whether or not those WRITEs
+ have made it to stable storage.
+
+ To avoid a "full resync", we need to persistently track these regions.
+
+ This is known as "write intent log", and can be implemented as on-disk
+ (coarse or fine grained) bitmap, or other meta data.
+
+ To avoid the overhead of frequent extra writes to this meta data area,
+ usually the condition is softened to regions that _may_ have been target of
+ in-flight WRITE IO, e.g. by only lazily clearing the on-disk write-intent
+ bitmap, trading frequency of meta data transactions against amount of
+ (possibly unnecessary) resync traffic.
+
+ If we set a hard limit on the area that may be "hot" at any given time, we
+ limit the amount of resync traffic needed for crash recovery.
+
+For recovery after replication link failure,
+ we need to resync all blocks that have been changed on the other replica
+ in the mean time, or, if both replica have been changed independently [*],
+ all blocks that have been changed on either replica in the mean time.
+ [*] usually as a result of a cluster split-brain and insufficient protection.
+ but there are valid use cases to do this on purpose.
+
+ Tracking those blocks can be implemented as "dirty bitmap".
+ Having it fine-grained reduces the amount of resync traffic.
+ It should also be persistent, to allow for reboots (or crashes)
+ while the replication link is down.
+
+There are various possible implementations for persistently storing
+write intent log information, three of which are mentioned here.
+
+"Chunk dirtying"
+ The on-disk "dirty bitmap" may be re-used as "write-intent" bitmap as well.
+ To reduce the frequency of bitmap updates for write-intent log purposes,
+ one could dirty "chunks" (of some size) at a time of the (fine grained)
+ on-disk bitmap, while keeping the in-memory "dirty" bitmap as clean as
+ possible, flushing it to disk again when a previously "hot" (and on-disk
+ dirtied as full chunk) area "cools down" again (no IO in flight anymore,
+ and none expected in the near future either).
+
+"Explicit (coarse) write intent bitmap"
+ An other implementation could chose a (probably coarse) explicit bitmap,
+ for write-intent log purposes, additionally to the fine grained dirty bitmap.
+
+"Activity log"
+ Yet an other implementation may keep track of the hot regions, by starting
+ with an empty set, and writing down a journal of region numbers that have
+ become "hot", or have "cooled down" again.
+
+ To be able to use a ring buffer for this journal of changes to the active
+ set, we not only record the actual changes to that set, but also record the
+ not changing members of the set in a round robin fashion. To do so, we use a
+ fixed (but configurable) number of slots which we can identify by index, and
+ associate region numbers (labels) with these indices.
+ For each transaction recording a change to the active set, we record the
+ change itself (index: -old_label, +new_label), and which index is associated
+ with which label (index: current_label) within a certain sliding window that
+ is moved further over the available indices with each such transaction.
+
+ Thus, for crash recovery, if the ringbuffer is sufficiently large, we can
+ accurately reconstruct the active set.
+
+ Sufficiently large depends only on maximum number of active objects, and the
+ size of the sliding window recording "index: current_label" associations within
+ each transaction.
+
+ This is what we call the "activity log".
+
+ Currently we need one activity log transaction per single label change, which
+ does not give much benefit over the "dirty chunks of bitmap" approach, other
+ than potentially less seeks.
+
+ We plan to change the transaction format to support multiple changes per
+ transaction, which then would reduce several (disjoint, "random") updates to
+ the bitmap into one transaction to the activity log ring buffer.
+*/
+
+/* this defines an element in a tracked set
+ * .colision is for hash table lookup.
+ * When we process a new IO request, we know its sector, thus can deduce the
+ * region number (label) easily. To do the label -> object lookup without a
+ * full list walk, we use a simple hash table.
+ *
+ * .list is on one of three lists:
+ * in_use: currently in use (refcnt > 0, lc_number != LC_FREE)
+ * lru: unused but ready to be reused or recycled
+ * (lc_refcnt == 0, lc_number != LC_FREE),

+ *
+ * an element is said to be "in the active set",
+ * if either on "in_use" or "lru", i.e. lc_number != LC_FREE.
+ *
+ * DRBD currently (May 2009) only uses 61 elements on the resync lru_cache
+ * (total memory usage 2 pages), and up to 3833 elements on the act_log
+ * lru_cache, totalling ~215 kB for 64bit architecture, ~53 pages.
+ *
+ * We usually do not actually free these objects again, but only "recycle"
+ * them, as the change "index: -old_label, +LC_FREE" would need a transaction
+ * as well. Which also means that using a kmem_cache to allocate the objects

+ * unless a particular usage is carefully commented. (the responsibility of

+ *
+ * A page may be used by anyone else who does a __get_free_page().

+ * be used through the normal accessor functions. The top bits of page->flags
+ * and page->virtual store page management information, but all other fields
+ * are unused and could be used privately, carefully. The management of this
+ * page is the responsibility of the one who allocated it, and those who have
+ * subsequently been given references to it.
+ *
+ * The other pages (we may call them "pagecache pages") are completely
+ * managed by the Linux memory manager: I/O, buffers, swapping etc.
+ * The following discussion applies only to them.
+ *
+ * A pagecache page contains an opaque `private' member, which belongs to the
+ * page's address_space. Usually, this is the address of a circular list of
+ * the page's disk buffers. PG_private must be set to tell the VM to call
+ * into the filesystem to release these pages.
+ *
+ * A page may belong to an inode's memory mapping. In this case, page->mapping
+ * is the pointer to the inode, and page->index is the file offset of the page,
+ * in units of PAGE_CACHE_SIZE.
+ *
+ * If pagecache pages are not associated with an inode, they are said to be
+ * anonymous pages. These may become associated with the swapcache, and in that
+ * case PG_swapcache is set, and page->private is an offset into the swapcache.
+ *
+ * In either case (swapcache or inode backed), the pagecache itself holds one
+ * reference to the page. Setting PG_private should also increment the
+ * refcount. The each user mapping also has a reference to the page.
+ *
+ * The pagecache pages are stored in a per-mapping radix tree, which is
+ * rooted at mapping->page_tree, and indexed by offset.
+ * Where 2.4 and early 2.6 kernels kept dirty/clean pages in per-address_space
+ * lists, we instead now tag pages as dirty/writeback in the radix tree.
+ *
+ * All pagecache pages may be subject to I/O:
+ * - inode pages may need to be read from disk,
+ * - inode pages which have been modified and are MAP_SHARED may need
+ * to be written back to the inode on disk,
+ * - anonymous pages (including MAP_PRIVATE file mappings) which have been

+ * Locking
+ * =======
+ *
+ * @lock is a softirq-safe spinlock protecting @queue as well as
+ * @cur_slot, @mrq and @state. These must always be updated
+ * at the same time while holding @lock.
+ *
+ * @irq_lock is an irq-safe spinlock protecting the INTMASK register
+ * to allow the interrupt handler to modify it directly. Held for only long
+ * enough to read-modify-write INTMASK and no other locks are grabbed when
+ * holding this one.
+ *
+ * The @mrq field of struct dw_mci_slot is also protected by @lock,
+ * and must always be written at the same time as the slot is added to
+ * @queue.
+ *
+ * @pending_events and @completed_events are accessed using atomic bit
+ * operations, so they don't need any locking.
+ *
+ * None of the fields touched by the interrupt handler need any
+ * locking. However, ordering is important: Before EVENT_DATA_ERROR or
+ * EVENT_DATA_COMPLETE is set in @pending_events, all data-related
+ * interrupts must be disabled and @data_status updated with a
+ * snapshot of SR. Similarly, before EVENT_CMD_COMPLETE is set, the
+ * CMDRDY interrupt must be disabled and @cmd_status updated with a
+ * snapshot of SR, and before EVENT_XFER_COMPLETE can be set, the
+ * bytes_xfered field of @data must be written. This is ensured by
+ * using barriers.

+ * 2) The array z_to_n[] maps each zone in the zonelist to its node
+ * id, so that we can efficiently evaluate whether that node is
+ * set in the current tasks mems_allowed.
+ *
+ * Both fullzones and z_to_n[] are one-to-one with the zonelist,
+ * indexed by a zones offset in the zonelist zones[] array.
+ *
+ * The get_page_from_freelist() routine does two scans. During the
+ * first scan, we skip zones whose corresponding bit in 'fullzones'
+ * is set or whose corresponding node in current->mems_allowed (which
+ * comes from cpusets) is not set. During the second scan, we bypass
+ * this zonelist_cache, to ensure we look methodically at each zone.
+ *
+ * Once per second, we zero out (zap) fullzones, forcing us to
+ * reconsider nodes that might have regained more free memory.
+ * The field last_full_zap is the time we last zapped fullzones.
+ *
+ * This mechanism reduces the amount of time we waste repeatedly
+ * reexaming zones for free memory when they just came up low on
+ * memory momentarilly ago.
+ *
+ * The zonelist_cache struct members logically belong in struct
+ * zonelist. However, the mempolicy zonelists constructed for
+ * MPOL_BIND are intentionally variable length (and usually much
+ * shorter). A general purpose mechanism for handling structs with
+ * multiple variable length members is more mechanism than we want
+ * here. We resort to some special case hackery instead.
+ *
+ * The MPOL_BIND zonelists don't need this zonelist_cache (in good
+ * part because they are shorter), so we put the fixed length stuff
+ * at the front of the zonelist struct, ending in a variable length
+ * zones[], as is needed by MPOL_BIND.
+ *
+ * Then we put the optional zonelist cache on the end of the zonelist
+ * struct. This optional stuff is found by a 'zlcache_ptr' pointer in
+ * the fixed length portion at the front of the struct. This pointer
+ * both enables us to find the zonelist cache, and in the case of
+ * MPOL_BIND zonelists, (which will just set the zlcache_ptr to NULL)
+ * to know that the zonelist cache is not there.
+ *
+ * The end result is that struct zonelists come in two flavors:
+ * 1) The full, fixed length version, shown below, and
+ * 2) The custom zonelists for MPOL_BIND.
+ * The custom MPOL_BIND zonelists have a NULL zlcache_ptr and no zlcache.
+ *
+ * Even though there may be multiple CPU cores on a node modifying
+ * fullzones or last_full_zap in the same zonelist_cache at the same
+ * time, we don't lock it. This is just hint data - if it is wrong now
+ * and then, the allocator will still function, perhaps a bit slower.

+ * This is usually set by a USB_DEVICE_*() macro, which sets all

+ * @idVendor: USB vendor ID for a device; numbers are assigned
+ * by the USB forum to its members.
+ * @idProduct: Vendor-assigned product ID.
+ * @bcdDevice_lo: Low end of range of vendor-assigned product version numbers.
+ * This is also used to identify individual product versions, for
+ * a range consisting of a single device.
+ * @bcdDevice_hi: High end of version number range. The range of product
+ * versions is inclusive.
+ * @bDeviceClass: Class of device; numbers are assigned
+ * by the USB forum. Products may choose to implement classes,
+ * or be vendor-specific. Device classes specify behavior of all
+ * the interfaces on a device.
+ * @bDeviceSubClass: Subclass of device; associated with bDeviceClass.
+ * @bDeviceProtocol: Protocol of device; associated with bDeviceClass.
+ * @bInterfaceClass: Class of interface; numbers are assigned
+ * by the USB forum. Products may choose to implement classes,
+ * or be vendor-specific. Interface classes specify behavior only
+ * of a given interface; other interfaces may support other classes.
+ * @bInterfaceSubClass: Subclass of interface; associated with bInterfaceClass.
+ * @bInterfaceProtocol: Protocol of interface; associated with bInterfaceClass.
+ * @bInterfaceNumber: Number of interface; composite devices may use
+ * fixed interface numbers to differentiate between vendor-specific
+ * interfaces.
+ * @driver_info: Holds information used by the driver. Usually it holds
+ * a pointer to a descriptor understood by the driver, or perhaps
+ * device flags.
+ *
+ * In most cases, drivers will create a table of device IDs by using
+ * USB_DEVICE(), or similar macros designed for that purpose.
+ * They will then export it to userspace using MODULE_DEVICE_TABLE(),
+ * and provide it to the USB core through their usb_driver structure.
+ *
+ * See the usb_match_id() function for information about how matches are
+ * performed. Briefly, you will normally use one of several macros to help
+ * construct these entries. Each entry you provide will either identify
+ * one or more specific products, or will identify a class of products
+ * which have agreed to behave the same. You should put the more specific
+ * matches towards the beginning of your table, so that driver_info can
+ * record quirks of specific products.

+ * @used_bytes: how many bytes of data this volume contains
+ * @used_ebs: how many physical eraseblocks of this volume actually contain any

+ * @usable_leb_size: how many bytes are available in logical eraseblocks of
+ * this volume
+ * @name_len: volume name length
+ * @name: volume name
+ * @cdev: UBI volume character device major and minor numbers
+ *
+ * The @corrupted flag is only relevant to static volumes and is always zero
+ * for dynamic ones. This is because UBI does not care about dynamic volume
+ * data protection and only cares about protecting static volume data.
+ *
+ * The @upd_marker flag is set if the volume update operation was interrupted.
+ * Before touching the volume data during the update operation, UBI first sets
+ * the update marker flag for this volume. If the volume update operation was
+ * further interrupted, the update marker indicates this. If the update marker
+ * is set, the contents of the volume is certainly damaged and a new volume
+ * update operation has to be started.
+ *
+ * To put it differently, @corrupted and @upd_marker fields have different
+ * semantics:
+ * o the @corrupted flag means that this static volume is corrupted for some
+ * reasons, but not because an interrupted volume update
+ * o the @upd_marker field means that the volume is damaged because of an
+ * interrupted update operation.
+ *
+ * I.e., the @corrupted flag is never set if the @upd_marker flag is set.
+ *
+ * The @used_bytes and @used_ebs fields are only really needed for static
+ * volumes and contain the number of bytes stored in this static volume and how
+ * many eraseblock this data occupies. In case of dynamic volumes, the
+ * @used_bytes field is equivalent to @size*@usable_leb_size, and the @used_ebs
+ * field is equivalent to @size.
+ *
+ * In general, logical eraseblock size is a property of the UBI device, not
+ * of the UBI volume. Indeed, the logical eraseblock size depends on the
+ * physical eraseblock size and on how much bytes UBI headers consume. But
+ * because of the volume alignment (@alignment), the usable size of logical
+ * eraseblocks if a volume may be less. The following equation is true:
+ * @usable_leb_size = LEB size - (LEB size mod @alignment),
+ * where LEB size is the logical eraseblock size defined by the UBI device.
+ *
+ * The alignment is multiple to the minimal flash input/output unit size or %1
+ * if all the available space is used.
+ *
+ * To put this differently, alignment may be considered is a way to change
+ * volume logical eraseblock sizes.

+/****************************************************************************
+ * ip_conntrack_h323_asn1.h - BER and PER decoding library for H.323
+ * conntrack/NAT module.
+ *
+ * Copyright (c) 2006 by Jing Min Zhao <zhaojingmin@users.sourceforge.net>
+ *
+ * This source code is licensed under General Public License version 2.
+ *
+ *
+ * This library is based on H.225 version 4, H.235 version 2 and H.245
+ * version 7. It is extremely optimized to decode only the absolutely
+ * necessary objects in a signal for Linux kernel NAT module use, so don't
+ * expect it to be a full ASN.1 library.
+ *
+ * Features:
+ *
+ * 1. Small. The total size of code plus data is less than 20 KB (IA32).
+ * 2. Fast. Decoding Netmeeting's Setup signal 1 million times on a PIII 866
+ * takes only 3.9 seconds.
+ * 3. No memory allocation. It uses a static object. No need to initialize or
+ * cleanup.
+ * 4. Thread safe.
+ * 5. Support embedded architectures that has no misaligned memory access
+ * support.
+ *
+ * Limitations:
+ *
+ * 1. At most 30 faststart entries. Actually this is limited by ethernet's MTU.
+ * If a Setup signal contains more than 30 faststart, the packet size will
+ * very likely exceed the MTU size, then the TPKT will be fragmented. I
+ * don't know how to handle this in a Netfilter module. Anybody can help?
+ * Although I think 30 is enough for most of the cases.
+ * 2. IPv4 addresses only.

+ *
+ * These counters are not meant to be human-readable, but are meant

+ * "iostat". As such, the counters are sampled by the tools over

+ * difference between two instantaneous samples and dividing that
+ * by the time between the samples.

+ *
+ * NODEMASK_SCRATCH
+ * When doing above logical AND, OR, XOR, Remap operations the callers tend to
+ * need temporary nodemask_t's on the stack. But if NODES_SHIFT is large,
+ * nodemask_t's consume too much stack space. NODEMASK_SCRATCH is a helper

+ integrated CPU, and the PC-8736[03456] integrated PC-peripheral
+ chips.
+
+ The GPIO units on these chips have the same pin architecture, but
+ the access methods differ. Thus, scx200_gpio and pc8736x_gpio
+ implement their own versions of these routines; and use the common
+ file-operations routines implemented in nsc_gpio module.
+
+ Copyright (c) 2005 Jim Cromie <jim.cromie@gmail.com>

+ * Various page->flags bits:
+ *
+ * PG_reserved is set for special pages, which can never be swapped out. Some
+ * of them might not even exist (eg empty_bad_page)...
+ *
+ * The PG_private bitflag is set on pagecache pages if they contain filesystem
+ * specific data (which is normally at page->private). It can be used by
+ * private allocations for its own usage.
+ *
+ * During initiation of disk I/O, PG_locked is set. This bit is set before I/O
+ * and cleared when writeback _starts_ or when read _completes_. PG_writeback
+ * is set before writeback starts and cleared when it finishes.
+ *
+ * PG_locked also pins a page in pagecache, and blocks truncation of the file
+ * while it is held.
+ *
+ * page_waitqueue(page) is a wait queue of all tasks waiting for the page
+ * to become unlocked.
+ *
+ * PG_uptodate tells whether the page's contents is valid. When a read
+ * completes, the page becomes uptodate, unless a disk I/O error happened.
+ *
+ * PG_referenced, PG_reclaim are used for page reclaim for anonymous and
+ * file-backed pagecache (see mm/vmscan.c).
+ *
+ * PG_error is set to indicate that an I/O error occurred on this page.
+ *
+ * PG_arch_1 is an architecture specific page state bit. The generic code
+ * guarantees that this bit is cleared for a page when it first is entered into
+ * the page cache.
+ *
+ * PG_highmem pages are not permanently mapped into the kernel virtual address
+ * space, they need to be kmapped separately for doing IO on the pages. The
+ * struct page (these bits with information) are always mapped into kernel
+ * address space...
+ *
+ * PG_hwpoison indicates that a page got corrupted in hardware and contains
+ * data with incorrect ECC bits that triggered a machine check. Accessing is
+ * not safe since it may cause another machine check. Don't touch!

+ * page is inserted into the same position in pagecache. That's OK: the

+ * Percpu refcounts:
+ * (C) 2012 Google, Inc.
+ * Author: Kent Overstreet <koverstreet@google.com>
+ *
+ * This implements a refcount with similar semantics to atomic_t - atomic_inc(),
+ * atomic_dec_and_test() - but percpu.
+ *
+ * There's one important difference between percpu refs and normal atomic_t
+ * refcounts; you have to keep track of your initial refcount, and then when you
+ * start shutting down you call percpu_ref_kill() _before_ dropping the initial
+ * refcount.
+ *
+ * The refcount will have a range of 0 to ((1U << 31) - 1), i.e. one bit less
+ * than an atomic_t - this is because of the way shutdown works, see
+ * percpu_ref_kill()/PERCPU_COUNT_BIAS.
+ *
+ * Before you call percpu_ref_kill(), percpu_ref_put() does not check for the
+ * refcount hitting 0 - it can't, if it was in percpu mode. percpu_ref_kill()
+ * puts the ref back in single atomic_t mode, collecting the per cpu refs and
+ * issuing the appropriate barriers, and then marks the ref as shutting down so
+ * that percpu_ref_put() will check for the ref hitting 0. After it returns,
+ * it's safe to drop the initial ref.
+ *
+ * USAGE:
+ *
+ * See fs/aio.c for some example usage; it's used there for struct kioctx, which
+ * is created when userspaces calls io_setup(), and destroyed when userspace
+ * calls io_destroy() or the process exits.
+ *
+ * In the aio code, kill_ioctx() is called when we wish to destroy a kioctx; it
+ * calls percpu_ref_kill(), then hlist_del_rcu() and synchronize_rcu() to remove
+ * the kioctx from the proccess's list of kioctxs - after that, there can't be
+ * any new users of the kioctx (from lookup_ioctx()) and it's then safe to drop
+ * the initial ref with percpu_ref_put().
+ *
+ * Code that does a two stage shutdown like this often needs some kind of
+ * explicit synchronization to ensure the initial refcount can only be dropped
+ * once - percpu_ref_kill() does this for you, it returns true once and false if
+ * someone else already called it. The aio code uses it this way, but it's not
+ * necessary if the code has some other mechanism to synchronize teardown.
+ * around.

+ * - If autonegotiation finishes, but there's no link, it sets

+ * - If autonegotiation did not finish after an arbitrary amount
+ * of time, autonegotiation should be tried again if the PHY
+ * supports "magic" autonegotiation (back to AN)
+ * - If it didn't finish, and no magic_aneg, move to FORCING.

+ * - If the timer notes that the link comes back, we move to RUNNING
+ * - config_aneg moves to AN

+ *
+ * FORCING: PHY is being configured with forced settings
+ * - if link is up, move to RUNNING
+ * - If link is down, we drop to the next highest setting, and

+ * RUNNING: PHY is currently up, running, and possibly sending
+ * and/or receiving packets
+ * - timer will set CHANGELINK if we're polling (this ensures the
+ * link state is polled every other cycle of this state machine,
+ * which makes it every other second)
+ * - irq will set CHANGELINK
+ * - config_aneg will set AN

+ * What is struct pid?
+ *
+ * A struct pid is the kernel's internal notion of a process identifier.
+ * It refers to individual tasks, process groups, and sessions. While
+ * there are processes attached to it the struct pid lives in a hash
+ * table, so it and then the processes that it refers to can be found
+ * quickly from the numeric pid value. The attached processes may be
+ * quickly accessed by following pointers from struct pid.
+ *
+ * Storing pid_t values in the kernel and referring to them later has a
+ * problem. The process originally with that pid may have exited and the
+ * pid allocator wrapped, and another process could have come along
+ * and been assigned that pid.
+ *
+ * Referring to user space processes by holding a reference to struct
+ * task_struct has a problem. When the user space process exits
+ * the now useless task_struct is still kept. A task_struct plus a
+ * stack consumes around 10K of low kernel memory. More precisely
+ * this is THREAD_SIZE + sizeof(struct task_struct). By comparison
+ * a struct pid is about 64 bytes.
+ *
+ * Holding a reference to struct pid solves both of these problems.
+ * It is small so holding a reference does not consume a lot of
+ * resources, and since a new struct pid is allocated when the numeric pid
+ * value is reused (when pids wrap around) we don't mistakenly refer to new
+ * processes.

+/**
+ * enum pin_config_param - possible pin configuration parameters
+ * @PIN_CONFIG_BIAS_DISABLE: disable any pin bias on the pin, a
+ * transition from say pull-up to pull-down implies that you disable
+ * pull-up in the process, this setting disables all biasing.
+ * @PIN_CONFIG_BIAS_HIGH_IMPEDANCE: the pin will be set to a high impedance
+ * mode, also know as "third-state" (tristate) or "high-Z" or "floating".
+ * On output pins this effectively disconnects the pin, which is useful
+ * if for example some other pin is going to drive the signal connected
+ * to it for a while. Pins used for input are usually always high
+ * impedance.
+ * @PIN_CONFIG_BIAS_BUS_HOLD: the pin will be set to weakly latch so that it
+ * weakly drives the last value on a tristate bus, also known as a "bus
+ * holder", "bus keeper" or "repeater". This allows another device on the
+ * bus to change the value by driving the bus high or low and switching to
+ * tristate. The argument is ignored.
+ * @PIN_CONFIG_BIAS_PULL_UP: the pin will be pulled up (usually with high
+ * impedance to VDD). If the argument is != 0 pull-up is enabled,
+ * if it is 0, pull-up is total, i.e. the pin is connected to VDD.
+ * @PIN_CONFIG_BIAS_PULL_DOWN: the pin will be pulled down (usually with high
+ * impedance to GROUND). If the argument is != 0 pull-down is enabled,
+ * if it is 0, pull-down is total, i.e. the pin is connected to GROUND.
+ * @PIN_CONFIG_BIAS_PULL_PIN_DEFAULT: the pin will be pulled up or down based
+ * on embedded knowledge of the controller hardware, like current mux
+ * function. The pull direction and possibly strength too will normally
+ * be decided completely inside the hardware block and not be readable
+ * from the kernel side.
+ * If the argument is != 0 pull up/down is enabled, if it is 0, the
+ * configuration is ignored. The proper way to disable it is to use
+ * @PIN_CONFIG_BIAS_DISABLE.
+ * @PIN_CONFIG_DRIVE_PUSH_PULL: the pin will be driven actively high and
+ * low, this is the most typical case and is typically achieved with two
+ * active transistors on the output. Setting this config will enable
+ * push-pull mode, the argument is ignored.
+ * @PIN_CONFIG_DRIVE_OPEN_DRAIN: the pin will be driven with open drain (open
+ * collector) which means it is usually wired with other output ports
+ * which are then pulled up with an external resistor. Setting this
+ * config will enable open drain mode, the argument is ignored.
+ * @PIN_CONFIG_DRIVE_OPEN_SOURCE: the pin will be driven with open source
+ * (open emitter). Setting this config will enable open source mode, the
+ * argument is ignored.
+ * @PIN_CONFIG_DRIVE_STRENGTH: the pin will sink or source at most the current
+ * passed as argument. The argument is in mA.
+ * @PIN_CONFIG_INPUT_ENABLE: enable the pin's input. Note that this does not
+ * affect the pin's ability to drive output. 1 enables input, 0 disables
+ * input.
+ * @PIN_CONFIG_INPUT_SCHMITT_ENABLE: control schmitt-trigger mode on the pin.
+ * If the argument != 0, schmitt-trigger mode is enabled. If it's 0,
+ * schmitt-trigger mode is disabled.
+ * @PIN_CONFIG_INPUT_SCHMITT: this will configure an input pin to run in
+ * schmitt-trigger mode. If the schmitt-trigger has adjustable hysteresis,
+ * the threshold value is given on a custom format as argument when
+ * setting pins to this mode.
+ * @PIN_CONFIG_INPUT_DEBOUNCE: this will configure the pin to debounce mode,
+ * which means it will wait for signals to settle when reading inputs. The
+ * argument gives the debounce time in usecs. Setting the
+ * argument to zero turns debouncing off.
+ * @PIN_CONFIG_POWER_SOURCE: if the pin can select between different power
+ * supplies, the argument to this parameter (on a custom format) tells
+ * the driver which alternative power source to use.
+ * @PIN_CONFIG_SLEW_RATE: if the pin can select slew rate, the argument to
+ * this parameter (on a custom format) tells the driver which alternative
+ * slew rate to use.
+ * @PIN_CONFIG_LOW_POWER_MODE: this will configure the pin for low power
+ * operation, if several modes of operation are supported these can be
+ * passed in the argument on a custom form, else just use argument 1
+ * to indicate low power mode, argument 0 turns low power mode off.
+ * @PIN_CONFIG_OUTPUT: this will configure the pin as an output. Use argument
+ * 1 to indicate high level, argument 0 to indicate low level. (Please
+ * see Documentation/pinctrl.txt, section "GPIO mode pitfalls" for a
+ * discussion around this parameter.)
+ * @PIN_CONFIG_END: this is the last enumerator for pin configurations, if
+ * you need to pass in custom configurations to the pin controller, use
+ * PIN_CONFIG_END+1 as the base offset.

+ brcmfmac_sdio_pdata.oob_irq_flags = IORESOURCE_IRQ |
+ IORESOURCE_IRQ_HIGHLEVEL;
+ platform_device_register(&brcmfmac_device);
+}
+ *
+ *
+ * Note: the brcmfmac can be loaded as module or be statically built-in into
+ * the kernel. If built-in then do note that it uses module_init (and
+ * module_exit) routines which equal device_initcall. So if you intend to
+ * create a module with the platform specific data for the brcmfmac and have
+ * it built-in to the kernel then use a higher initcall then device_initcall
+ * (see init.h). If this is not done then brcmfmac will load without problems
+ * but will not pickup the platform data.
+ *
+ * When the driver does not "detect" platform driver data then it will continue
+ * without reporting anything and just assume there is no data needed. Which is
+ * probably true for most platforms.
+ *
+ * Explanation of the platform_data fields:
+ *
+ * drive_strength: is the preferred drive_strength to be used for the SDIO
+ * pins. If 0 then a default value will be used. This is the target drive
+ * strength, the exact drive strength which will be used depends on the
+ * capabilities of the device.
+ *
+ * oob_irq_supported: does the board have support for OOB interrupts. SDIO
+ * in-band interrupts are relatively slow and for having less overhead on
+ * interrupt processing an out of band interrupt can be used. If the HW
+ * supports this then enable this by setting this field to true and configure
+ * the oob related fields.
+ *
+ * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are
+ * used for registering the irq using request_irq function.
+ *
+ * broken_sg_support: flag for broken sg list support of SDIO host controller.
+ * Set this to true if the SDIO host controller has higher align requirement
+ * than 32 bytes for each scatterlist item.
+ *
+ * sd_head_align: alignment requirement for start of data buffer
+ *
+ * sd_sgentry_align: length alignment requirement for each sg entry
+ *
+ * power_on: This function is called by the brcmfmac when the module gets
+ * loaded. This can be particularly useful for low power devices. The platform
+ * spcific routine may for example decide to power up the complete device.
+ * If there is no use-case for this function then provide NULL.
+ *
+ * power_off: This function is called by the brcmfmac when the module gets
+ * unloaded. At this point the device can be powered down or otherwise be reset.
+ * So if an actual power_off is not supported but reset is then reset the device
+ * when this function gets called. This can be particularly useful for low power
+ * devices. If there is no use-case for this function (either power-down or
+ * reset) then provide NULL.
+ *
+ * reset: This function can get called if the device communication broke down.
+ * This functionality is particularly useful in case of SDIO type devices. It is
+ * possible to reset a dongle via sdio data interface, but it requires that
+ * this is fully functional. This function is chip/module specific and this
+ * function should return only after the complete reset has completed.

+ * This EDMA3 programming framework exposes two basic kinds of resource:
+ *
+ * Channel Triggers transfers, usually from a hardware event but
+ * also manually or by "chaining" from DMA completions.
+ * Each channel is coupled to a Parameter RAM (PaRAM) slot.
+ *
+ * Slot Each PaRAM slot holds a DMA transfer descriptor (PaRAM
+ * "set"), source and destination addresses, a link to a
+ * next PaRAM slot (if any), options for the transfer, and
+ * instructions for updating those addresses. There are
+ * more than twice as many slots as event channels.
+ *
+ * Each PaRAM set describes a sequence of transfers, either for one large
+ * buffer or for several discontiguous smaller buffers. An EDMA transfer
+ * is driven only from a channel, which performs the transfers specified
+ * in its PaRAM slot until there are no more transfers. When that last
+ * transfer completes, the "link" field may be used to reload the channel's
+ * PaRAM slot with a new transfer descriptor.
+ *
+ * The EDMA Channel Controller (CC) maps requests from channels into physical
+ * Transfer Controller (TC) requests when the channel triggers (by hardware
+ * or software events, or by chaining). The two physical DMA channels provided
+ * by the TCs are thus shared by many logical channels.
+ *
+ * DaVinci hardware also has a "QDMA" mechanism which is not currently
+ * supported through this interface. (DSP firmware uses it though.)

+ *
+ * Based on simple lists (include/linux/list.h).
+ *
+ * This is a priority-sorted list of nodes; each node has a
+ * priority from INT_MIN (highest) to INT_MAX (lowest).
+ *
+ * Addition is O(K), removal is O(1), change of priority of a node is
+ * O(K) and K is the number of RT priority levels used in the system.
+ * (1 <= K <= 99)
+ *
+ * This list is really a list of lists:
+ *
+ * - The tier 1 list is the prio_list, different priority nodes.
+ *
+ * - The tier 2 list is the node_list, serialized nodes.
+ *
+ * Simple ASCII art explanation:
+ *
+ * pl:prio_list (only for plist_node)
+ * nl:node_list
+ * HEAD| NODE(S)
+ * |
+ * ||------------------------------------|
+ * ||->|pl|<->|pl|<--------------->|pl|<-|
+ * | |10| |21| |21| |21| |40| (prio)
+ * | | | | | | | | | | |
+ * | | | | | | | | | | |
+ * |->|nl|<->|nl|<->|nl|<->|nl|<->|nl|<->|nl|<-|
+ * |-------------------------------------------|
+ *
+ * The nodes on the prio_list list are sorted by priority to simplify
+ * the insertion of new nodes. There are no nodes with duplicate
+ * priorites on the list.
+ *
+ * The nodes on the node_list are ordered by priority and can contain
+ * entries which have the same priority. Those entries are ordered
+ * FIFO
+ *
+ * Addition means: look for the prio_list node in the prio_list
+ * for the priority of the node and insert it before the node_list
+ * entry of the next prio_list node. If it is the first node of
+ * that priority, add it to the prio_list in the right position and
+ * insert it into the serialized node_list list
+ *
+ * Removal means remove it from the node_list and remove it from
+ * the prio_list if the node_list list_head is non empty. In case
+ * of removal from the prio_list it must be checked whether other
+ * entries of the same priority are on the list or not. If there
+ * is another entry of the same priority then this entry has to
+ * replace the removed entry on the prio_list. If the entry which
+ * is removed is the only entry of this priority then a simple
+ * remove from both list is sufficient.
+ *
+ * INT_MIN is the highest priority, 0 is the medium highest, INT_MAX
+ * is lowest priority.
+ *
+ * No locking is done, up to the caller.

+/**
+ * struct dev_pm_ops - device PM callbacks
+ *
+ * Several device power state transitions are externally visible, affecting
+ * the state of pending I/O queues and (for drivers that touch hardware)
+ * interrupts, wakeups, DMA, and other hardware state. There may also be
+ * internal transitions to various low-power modes which are transparent
+ * to the rest of the driver stack (such as a driver that's ON gating off
+ * clocks which are not in active use).
+ *
+ * The externally visible transitions are handled with the help of callbacks
+ * included in this structure in such a way that two levels of callbacks are
+ * involved. First, the PM core executes callbacks provided by PM domains,
+ * device types, classes and bus types. They are the subsystem-level callbacks
+ * supposed to execute callbacks provided by device drivers, although they may
+ * choose not to do that. If the driver callbacks are executed, they have to
+ * collaborate with the subsystem-level callbacks to achieve the goals
+ * appropriate for the given system transition, given transition phase and the
+ * subsystem the device belongs to.
+ *
+ * @prepare: The principal role of this callback is to prevent new children of
+ * the device from being registered after it has returned (the driver's
+ * subsystem and generally the rest of the kernel is supposed to prevent
+ * new calls to the probe method from being made too once @prepare() has
+ * succeeded). If @prepare() detects a situation it cannot handle (e.g.
+ * registration of a child already in progress), it may return -EAGAIN, so
+ * that the PM core can execute it once again (e.g. after a new child has
+ * been registered) to recover from the race condition.
+ * This method is executed for all kinds of suspend transitions and is
+ * followed by one of the suspend callbacks: @suspend(), @freeze(), or
+ * @poweroff(). If the transition is a suspend to memory or standby (that
+ * is, not related to hibernation), the return value of @prepare() may be
+ * used to indicate to the PM core to leave the device in runtime suspend
+ * if applicable. Namely, if @prepare() returns a positive number, the PM
+ * core will understand that as a declaration that the device appears to be
+ * runtime-suspended and it may be left in that state during the entire
+ * transition and during the subsequent resume if all of its descendants
+ * are left in runtime suspend too. If that happens, @complete() will be
+ * executed directly after @prepare() and it must ensure the proper
+ * functioning of the device after the system resume.
+ * The PM core executes subsystem-level @prepare() for all devices before
+ * starting to invoke suspend callbacks for any of them, so generally
+ * devices may be assumed to be functional or to respond to runtime resume
+ * requests while @prepare() is being executed. However, device drivers
+ * may NOT assume anything about the availability of user space at that
+ * time and it is NOT valid to request firmware from within @prepare()
+ * (it's too late to do that). It also is NOT valid to allocate
+ * substantial amounts of memory from @prepare() in the GFP_KERNEL mode.
+ * [To work around these limitations, drivers may register suspend and
+ * hibernation notifiers to be executed before the freezing of tasks.]
+ *
+ * @complete: Undo the changes made by @prepare(). This method is executed for
+ * all kinds of resume transitions, following one of the resume callbacks:
+ * @resume(), @thaw(), @restore(). Also called if the state transition
+ * fails before the driver's suspend callback: @suspend(), @freeze() or
+ * @poweroff(), can be executed (e.g. if the suspend callback fails for one
+ * of the other devices that the PM core has unsuccessfully attempted to
+ * suspend earlier).
+ * The PM core executes subsystem-level @complete() after it has executed
+ * the appropriate resume callbacks for all devices. If the corresponding
+ * @prepare() at the beginning of the suspend transition returned a
+ * positive number and the device was left in runtime suspend (without
+ * executing any suspend and resume callbacks for it), @complete() will be
+ * the only callback executed for the device during resume. In that case,
+ * @complete() must be prepared to do whatever is necessary to ensure the
+ * proper functioning of the device after the system resume. To this end,
+ * @complete() can check the power.direct_complete flag of the device to
+ * learn whether (unset) or not (set) the previous suspend and resume
+ * callbacks have been executed for it.
+ *
+ * @suspend: Executed before putting the system into a sleep state in which the
+ * contents of main memory are preserved. The exact action to perform
+ * depends on the device's subsystem (PM domain, device type, class or bus
+ * type), but generally the device must be quiescent after subsystem-level
+ * @suspend() has returned, so that it doesn't do any I/O or DMA.
+ * Subsystem-level @suspend() is executed for all devices after invoking
+ * subsystem-level @prepare() for all of them.
+ *
+ * @suspend_late: Continue operations started by @suspend(). For a number of
+ * devices @suspend_late() may point to the same callback routine as the
+ * runtime suspend callback.
+ *
+ * @resume: Executed after waking the system up from a sleep state in which the
+ * contents of main memory were preserved. The exact action to perform
+ * depends on the device's subsystem, but generally the driver is expected
+ * to start working again, responding to hardware events and software
+ * requests (the device itself may be left in a low-power state, waiting
+ * for a runtime resume to occur). The state of the device at the time its
+ * driver's @resume() callback is run depends on the platform and subsystem
+ * the device belongs to. On most platforms, there are no restrictions on
+ * availability of resources like clocks during @resume().
+ * Subsystem-level @resume() is executed for all devices after invoking
+ * subsystem-level @resume_noirq() for all of them.
+ *
+ * @resume_early: Prepare to execute @resume(). For a number of devices
+ * @resume_early() may point to the same callback routine as the runtime
+ * resume callback.
+ *
+ * @freeze: Hibernation-specific, executed before creating a hibernation image.
+ * Analogous to @suspend(), but it should not enable the device to signal
+ * wakeup events or change its power state. The majority of subsystems
+ * (with the notable exception of the PCI bus type) expect the driver-level
+ * @freeze() to save the device settings in memory to be used by @restore()
+ * during the subsequent resume from hibernation.
+ * Subsystem-level @freeze() is executed for all devices after invoking
+ * subsystem-level @prepare() for all of them.
+ *
+ * @freeze_late: Continue operations started by @freeze(). Analogous to
+ * @suspend_late(), but it should not enable the device to signal wakeup
+ * events or change its power state.
+ *
+ * @thaw: Hibernation-specific, executed after creating a hibernation image OR
+ * if the creation of an image has failed. Also executed after a failing
+ * attempt to restore the contents of main memory from such an image.
+ * Undo the changes made by the preceding @freeze(), so the device can be
+ * operated in the same way as immediately before the call to @freeze().
+ * Subsystem-level @thaw() is executed for all devices after invoking
+ * subsystem-level @thaw_noirq() for all of them. It also may be executed
+ * directly after @freeze() in case of a transition error.
+ *
+ * @thaw_early: Prepare to execute @thaw(). Undo the changes made by the
+ * preceding @freeze_late().
+ *
+ * @poweroff: Hibernation-specific, executed after saving a hibernation image.
+ * Analogous to @suspend(), but it need not save the device's settings in
+ * memory.
+ * Subsystem-level @poweroff() is executed for all devices after invoking
+ * subsystem-level @prepare() for all of them.
+ *
+ * @poweroff_late: Continue operations started by @poweroff(). Analogous to
+ * @suspend_late(), but it need not save the device's settings in memory.
+ *
+ * @restore: Hibernation-specific, executed after restoring the contents of main
+ * memory from a hibernation image, analogous to @resume().
+ *
+ * @restore_early: Prepare to execute @restore(), analogous to @resume_early().
+ *
+ * @suspend_noirq: Complete the actions started by @suspend(). Carry out any
+ * additional operations required for suspending the device that might be
+ * racing with its driver's interrupt handler, which is guaranteed not to
+ * run while @suspend_noirq() is being executed.
+ * It generally is expected that the device will be in a low-power state
+ * (appropriate for the target system sleep state) after subsystem-level
+ * @suspend_noirq() has returned successfully. If the device can generate
+ * system wakeup signals and is enabled to wake up the system, it should be
+ * configured to do so at that time. However, depending on the platform
+ * and device's subsystem, @suspend() or @suspend_late() may be allowed to
+ * put the device into the low-power state and configure it to generate
+ * wakeup signals, in which case it generally is not necessary to define
+ * @suspend_noirq().
+ *
+ * @resume_noirq: Prepare for the execution of @resume() by carrying out any
+ * operations required for resuming the device that might be racing with
+ * its driver's interrupt handler, which is guaranteed not to run while
+ * @resume_noirq() is being executed.
+ *
+ * @freeze_noirq: Complete the actions started by @freeze(). Carry out any
+ * additional operations required for freezing the device that might be
+ * racing with its driver's interrupt handler, which is guaranteed not to
+ * run while @freeze_noirq() is being executed.
+ * The power state of the device should not be changed by either @freeze(),
+ * or @freeze_late(), or @freeze_noirq() and it should not be configured to
+ * signal system wakeup by any of these callbacks.
+ *
+ * @thaw_noirq: Prepare for the execution of @thaw() by carrying out any
+ * operations required for thawing the device that might be racing with its
+ * driver's interrupt handler, which is guaranteed not to run while
+ * @thaw_noirq() is being executed.
+ *
+ * @poweroff_noirq: Complete the actions started by @poweroff(). Analogous to
+ * @suspend_noirq(), but it need not save the device's settings in memory.
+ *
+ * @restore_noirq: Prepare for the execution of @restore() by carrying out any
+ * operations required for thawing the device that might be racing with its
+ * driver's interrupt handler, which is guaranteed not to run while
+ * @restore_noirq() is being executed. Analogous to @resume_noirq().
+ *
+ * All of the above callbacks, except for @complete(), return error codes.
+ * However, the error codes returned by the resume operations, @resume(),
+ * @thaw(), @restore(), @resume_noirq(), @thaw_noirq(), and @restore_noirq(), do
+ * not cause the PM core to abort the resume transition during which they are
+ * returned. The error codes returned in those cases are only printed by the PM
+ * core to the system logs for debugging purposes. Still, it is recommended
+ * that drivers only return error codes from their resume methods in case of an
+ * unrecoverable failure (i.e. when the device being handled refuses to resume
+ * and becomes unusable) to allow us to modify the PM core in the future, so
+ * that it can avoid attempting to handle devices that failed to resume and
+ * their children.
+ *
+ * It is allowed to unregister devices while the above callbacks are being
+ * executed. However, a callback routine must NOT try to unregister the device
+ * it was called for, although it may unregister children of that device (for
+ * example, if it detects that a child was unplugged while the system was
+ * asleep).
+ *
+ * Refer to Documentation/power/devices.txt for more information about the role
+ * of the above callbacks in the system suspend process.
+ *
+ * There also are callbacks related to runtime power management of devices.
+ * Again, these callbacks are executed by the PM core only for subsystems
+ * (PM domains, device types, classes and bus types) and the subsystem-level
+ * callbacks are supposed to invoke the driver callbacks. Moreover, the exact
+ * actions to be performed by a device driver's callbacks generally depend on
+ * the platform and subsystem the device belongs to.
+ *
+ * @runtime_suspend: Prepare the device for a condition in which it won't be
+ * able to communicate with the CPU(s) and RAM due to power management.
+ * This need not mean that the device should be put into a low-power state.
+ * For example, if the device is behind a link which is about to be turned
+ * off, the device may remain at full power. If the device does go to low
+ * power and is capable of generating runtime wakeup events, remote wakeup
+ * (i.e., a hardware mechanism allowing the device to request a change of
+ * its power state via an interrupt) should be enabled for it.
+ *
+ * @runtime_resume: Put the device into the fully active state in response to a
+ * wakeup event generated by hardware or at the request of software. If
+ * necessary, put the device into the full-power state and restore its
+ * registers, so that it is fully operational.
+ *
+ * @runtime_idle: Device appears to be inactive and it might be put into a
+ * low-power state if all of the necessary conditions are satisfied.
+ * Check these conditions, and return 0 if it's appropriate to let the PM
+ * core queue a suspend request for the device.
+ *
+ * Refer to Documentation/power/runtime_pm.txt for more information about the
+ * role of the above callbacks in device runtime power management.

+ * PRETHAW Quiesce as if for FREEZE; additionally, prepare for restoring

+/**
+ * Radix-tree synchronization
+ *
+ * The radix-tree API requires that users provide all synchronisation (with
+ * specific exceptions, noted below).
+ *
+ * Synchronization of access to the data items being stored in the tree, and
+ * management of their lifetimes must be completely managed by API users.
+ *
+ * For API usage, in general,
+ * - any function _modifying_ the tree or tags (inserting or deleting
+ * items, setting or clearing tags) must exclude other modifications, and
+ * exclude any functions reading the tree.
+ * - any function _reading_ the tree or tags (looking up items or tags,
+ * gang lookups) must exclude modifications to the tree, but may occur
+ * concurrently with other readers.
+ *
+ * The notable exceptions to this rule are the following functions:
+ * __radix_tree_lookup
+ * radix_tree_lookup
+ * radix_tree_lookup_slot
+ * radix_tree_tag_get
+ * radix_tree_gang_lookup
+ * radix_tree_gang_lookup_slot
+ * radix_tree_gang_lookup_tag
+ * radix_tree_gang_lookup_tag_slot
+ * radix_tree_tagged
+ *
+ * The first 7 functions are able to be called locklessly, using RCU. The
+ * caller must ensure calls to these functions are made within rcu_read_lock()
+ * regions. Other readers (lock-free or otherwise) and modifications may be
+ * running concurrently.
+ *
+ * It is still required that the caller manage the synchronization and lifetimes
+ * of the items. So if RCU lock-free lookups are used, typically this would mean
+ * that the items have their own locks, or are amenable to lock-free access; and
+ * that the items are freed by RCU (or only freed after having been deleted from
+ * the radix tree *and* a synchronize_rcu() grace period).
+ *
+ * (Note, rcu_assign_pointer and rcu_dereference are not needed to control
+ * access to data items when inserting into or looking up from the radix tree)
+ *
+ * Note that the value returned by radix_tree_tag_get() may not be relied upon
+ * if only the RCU read lock is held. Functions to set/clear tags and to
+ * delete nodes running concurrently with it may affect its result such that
+ * two consecutive reads in the same locked section may return different
+ * values. If reliability is required, modification functions must also be
+ * excluded from concurrency.
+ *
+ * radix_tree_tagged is able to be called without locking or RCU.

+ *
+ * When synchronize_rcu() is invoked on one CPU while other CPUs
+ * are within RCU read-side critical sections, then the
+ * synchronize_rcu() is guaranteed to block until after all the other
+ * CPUs exit their critical sections. Similarly, if call_rcu() is invoked
+ * on one CPU while other CPUs are within RCU read-side critical
+ * sections, invocation of the corresponding RCU callback is deferred
+ * until after the all the other CPUs exit their critical sections.
+ *
+ * Note, however, that RCU callbacks are permitted to run concurrently
+ * with new RCU read-side critical sections. One way that this can happen
+ * is via the following sequence of events: (1) CPU 0 enters an RCU
+ * read-side critical section, (2) CPU 1 invokes call_rcu() to register
+ * an RCU callback, (3) CPU 0 exits the RCU read-side critical section,
+ * (4) CPU 2 enters a RCU read-side critical section, (5) the RCU
+ * callback is invoked. This is legal, because the RCU read-side critical
+ * section that was running concurrently with the call_rcu() (and which
+ * therefore might be referencing something that the corresponding RCU
+ * callback would free up) has completed before the corresponding
+ * RCU callback is invoked.
+ *
+ * RCU read-side critical sections may be nested. Any deferred actions
+ * will be deferred until the outermost RCU read-side critical section
+ * completes.
+ *
+ * You can avoid reading and understanding the next paragraph by
+ * following this rule: don't put anything in an rcu_read_lock() RCU
+ * read-side critical section that would block in a !PREEMPT kernel.
+ * But if you want the full story, read on!
+ *
+ * In non-preemptible RCU implementations (TREE_RCU and TINY_RCU),
+ * it is illegal to block while in an RCU read-side critical section.
+ * In preemptible RCU implementations (PREEMPT_RCU) in CONFIG_PREEMPT
+ * kernel builds, RCU read-side critical sections may be preempted,
+ * but explicit blocking is illegal. Finally, in preemptible RCU
+ * implementations in real-time (with -rt patchset) kernel builds, RCU
+ * read-side critical sections may be preempted and they may also block, but
+ * only when acquiring spinlocks that are subject to priority inheritance.

+ * In most situations, rcu_read_unlock() is immune from deadlock.
+ * However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
+ * is responsible for deboosting, which it does via rt_mutex_unlock().
+ * Unfortunately, this function acquires the scheduler's runqueue and
+ * priority-inheritance spinlocks. This means that deadlock could result
+ * if the caller of rcu_read_unlock() already holds one of these locks or
+ * any lock that is ever acquired while holding them; or any lock which
+ * can be taken from interrupt context because rcu_boost()->rt_mutex_lock()
+ * does not disable irqs while taking ->wait_lock.
+ *
+ * That said, RCU readers are never priority boosted unless they were
+ * preempted. Therefore, one way to avoid deadlock is to make sure
+ * that preemption never happens within any RCU read-side critical
+ * section whose outermost rcu_read_unlock() is called with one of
+ * rt_mutex_unlock()'s locks held. Such preemption can be avoided in
+ * a number of ways, for example, by invoking preempt_disable() before
+ * critical section's outermost rcu_read_lock().
+ *
+ * Given that the set of locks acquired by rt_mutex_unlock() might change
+ * at any time, a somewhat more future-proofed approach is to make sure
+ * that that preemption never happens within any RCU read-side critical
+ * section whose outermost rcu_read_unlock() is called with irqs disabled.
+ * This approach relies on the fact that rt_mutex_unlock() currently only
+ * acquires irq-disabled locks.
+ *
+ * The second of these two approaches is best in most situations,
+ * however, the first approach can also be useful, at least to those

+ * (a register is writeable if it belongs to one of the ranges
+ * specified by wr_table).

+ * specified by rd_table).

+ * check is performed on such table (a register is precious if

+ * @lock: Optional lock callback (overrides regmap's default lock
+ * function, based on spinlock or mutex).
+ * @unlock: As above for unlocking.
+ * @lock_arg: this field is passed as the only argument of lock/unlock
+ * functions (ignored in case regular lock/unlock functions
+ * are not overridden).
+ * @reg_read: Optional callback that if filled will be used to perform
+ * all the reads from the registers. Should only be provided for
+ * devices whose read operation cannot be represented as a simple
+ * read operation on a bus such as SPI, I2C, etc. Most of the
+ * devices do not need this.
+ * @reg_write: Same as above for writing.
+ * @fast_io: Register IO is fast. Use a spinlock instead of a mutex
+ * to perform locking. This field is ignored if custom lock/unlock
+ * functions are used (see fields lock/unlock of struct regmap_config).
+ * This field is a duplicate of a similar file in
+ * 'struct regmap_bus' and serves exact same purpose.
+ * Use it only for "no-bus" cases.
+ * @max_register: Optional, specifies the maximum valid register index.
+ * @wr_table: Optional, points to a struct regmap_access_table specifying
+ * valid ranges for write access.
+ * @rd_table: As above, for read access.
+ * @volatile_table: As above, for volatile registers.
+ * @precious_table: As above, for precious registers.
+ * @reg_defaults: Power on reset values for registers (for use with

+ * @num_reg_defaults: Number of elements in reg_defaults.
+ *
+ * @read_flag_mask: Mask to be set in the top byte of the register when doing
+ * a read.
+ * @write_flag_mask: Mask to be set in the top byte of the register when doing
+ * a write. If both read_flag_mask and write_flag_mask are
+ * empty the regmap_bus default masks are used.
+ * @use_single_rw: If set, converts the bulk read and write operations into
+ * a series of single read and write operations. This is useful
+ * for device that does not support bulk read and write.
+ * @can_multi_write: If set, the device supports the multi write mode of bulk
+ * write operations, if clear multi write requests will be
+ * split into individual write operations
+ *

+ * @bias: Bias from natural indexing.
+ * @core_note_type: ELF note @n_type value used in core dumps.
+ * @get: Function to fetch values.
+ * @set: Function to store values.
+ * @active: Function to report if regset is active, or %NULL.
+ * @writeback: Function to write data back to user memory, or %NULL.
+ *
+ * This data structure describes a machine resource we call a register set.
+ * This is part of the state of an individual thread, not necessarily
+ * actual CPU registers per se. A register set consists of a number of
+ * similar slots, given by @n. Each slot is @size bytes, and aligned to
+ * @align bytes (which is at least @size).
+ *
+ * These functions must be called only on the current thread or on a
+ * thread that is in %TASK_STOPPED or %TASK_TRACED state, that we are
+ * guaranteed will not be woken up and return to user mode, and that we
+ * have called wait_task_inactive() on. (The target thread always might
+ * wake up for SIGKILL while these functions are working, in which case
+ * that thread's user_regset state might be scrambled.)
+ *
+ * The @pos argument must be aligned according to @align; the @count
+ * argument must be a multiple of @size. These functions are not
+ * responsible for checking for invalid arguments.
+ *
+ * When there is a natural value to use as an index, @bias gives the
+ * difference between the natural index and the slot index for the
+ * register set. For example, x86 GDT segment descriptors form a regset;
+ * the segment selector produces a natural index, but only a subset of
+ * that index space is available as a regset (the TLS slots); subtracting
+ * @bias from a segment selector index value computes the regset slot.
+ *
+ * If nonzero, @core_note_type gives the n_type field (NT_* value)
+ * of the core file note in which this regset's data appears.
+ * NT_PRSTATUS is a special case in that the regset data starts at
+ * offsetof(struct elf_prstatus, pr_reg) into the note data; that is
+ * part of the per-machine ELF formats userland knows about. In
+ * other cases, the core file note contains exactly the whole regset
+ * (@n * @size) and nothing else. The core file note is normally
+ * omitted when there is an @active function and it returns zero.

+ * idling. Regulator r has > 90% efficiency in NORMAL mode at loads > 100mA
+ * but this drops rapidly to 60% when below 100mA. Regulator r has > 90%
+ * efficiency in IDLE mode at loads < 10mA. Thus regulator r will operate

+ * Regulator operating modes.
+ *
+ * Regulators can run in a variety of different operating modes depending on
+ * output load. This allows further system power savings by selecting the
+ * best (and most efficient) regulator mode for a desired load.
+ *
+ * Most drivers will only care about NORMAL. The modes below are generic and
+ * will probably not match the naming convention of your regulator data sheet
+ * but should match the use cases in the datasheet.
+ *
+ * In order of power efficiency (least efficient at top).
+ *
+ * Mode Description
+ * FAST Regulator can handle fast changes in it's load.
+ * e.g. useful in CPU voltage & frequency scaling where
+ * load can quickly increase with CPU frequency increases.
+ *
+ * NORMAL Normal regulator power supply mode. Most drivers will
+ * use this mode.
+ *
+ * IDLE Regulator runs in a more efficient mode for light
+ * loads. Can be used for devices that have a low power
+ * requirement during periods of inactivity. This mode
+ * may be more noisy than NORMAL and may not be able
+ * to handle fast load switching.
+ *
+ * STANDBY Regulator runs in the most efficient mode for very
+ * light loads. Can be used by devices when they are
+ * in a sleep/standby state. This mode is likely to be
+ * the most noisy and may not be able to handle fast load
+ * switching.
+ *
+ * NOTE: Most regulators will only support a subset of these modes. Some
+ * will only just support NORMAL.
+ *
+ * These modes can be OR'ed together to make up a mask of valid register modes.

+ * These request entries should precede other firmware resource entries,

+ *
+ * Allocating memory this way helps utilizing the reserved physical memory

+ *
+ * If the firmware is compiled with static addresses, then @da should specify

+ * hardware accelerators which access the physical memory directly (this
+ * is the case with OMAP4 for instance). In that case, the host will
+ * overwrite @pa with the dynamically allocated physical address.
+ * Generally we don't want to expose physical addresses if we don't have to
+ * (remote processors are generally _not_ trusted), so we might want to

+ * frequency is set to 0Hz.

+ * Not currently used by the rtc-ds1685 driver because the RTC core removed
+ * support for hardware-generated periodic-interrupts in favour of
+ * hrtimer-generated interrupts. But these defines are kept around for use
+ * in userland, as documentation to the hardware, and possible future use if

+ * Extended scheduling parameters data structure.
+ *
+ * This is needed because the original struct sched_param can not be
+ * altered without introducing ABI issues with legacy applications
+ * (e.g., in sched_getparam()).
+ *
+ * However, the possibility of specifying more than just a priority for
+ * the tasks may be useful for a wide variety of application fields, e.g.,
+ * multimedia, streaming, automation and control, and many others.
+ *
+ * This variant (sched_attr) is meant at describing a so-called
+ * sporadic time-constrained task. In such model a task is specified by:
+ * - the activation period or minimum instance inter-arrival time;
+ * - the maximum (or average, depending on the actual scheduling
+ * discipline) computation time of all instances, a.k.a. runtime;
+ * - the deadline (relative to the actual activation time) of each
+ * instance.
+ * Very briefly, a periodic (sporadic) task asks for the execution of
+ * some specific computation --which is typically called an instance--
+ * (at most) every period. Moreover, each instance typically lasts no more
+ * than the runtime and must be completed by time instant t equal to
+ * the instance activation time + the deadline.
+ *
+ * This is reflected by the actual fields of the sched_attr structure:
+ *
+ * @size size of the structure, for fwd/bwd compat.
+ *
+ * @sched_policy task's scheduling policy
+ * @sched_flags for customizing the scheduler behaviour
+ * @sched_nice task's nice value (SCHED_NORMAL/BATCH)
+ * @sched_priority task's static priority (SCHED_FIFO/RR)
+ * @sched_deadline representative of the task's deadline
+ * @sched_runtime representative of the task's runtime
+ * @sched_period representative of the task's period
+ *
+ * Given this task model, there are a multiplicity of scheduling algorithms
+ * and policies, that can be used to ensure all the tasks will make their
+ * timing constraints.
+ *
+ * As of now, the SCHED_DEADLINE policy (sched_dl scheduling class) is the
+ * only user of this new interface. More information about the algorithm
+ * available in the scheduling class file or in Documentation/.

+ * struct security_operations - main security structure
+ *
+ * Security module identifier.
+ *
+ * @name:
+ * A string that acts as a unique identifier for the LSM with max number
+ * of characters = SECURITY_NAME_MAX.
+ *
+ * Security hooks for program execution operations.
+ *
+ * @bprm_set_creds:
+ * Save security information in the bprm->security field, typically based
+ * on information about the bprm->file, for later use by the apply_creds
+ * hook. This hook may also optionally check permissions (e.g. for
+ * transitions between security domains).
+ * This hook may be called multiple times during a single execve, e.g. for
+ * interpreters. The hook can tell whether it has already been called by
+ * checking to see if @bprm->security is non-NULL. If so, then the hook
+ * may decide either to retain the security information saved earlier or
+ * to replace it.
+ * @bprm contains the linux_binprm structure.
+ * Return 0 if the hook is successful and permission is granted.
+ * @bprm_check_security:
+ * This hook mediates the point when a search for a binary handler will
+ * begin. It allows a check the @bprm->security value which is set in the
+ * preceding set_creds call. The primary difference from set_creds is
+ * that the argv list and envp list are reliably available in @bprm. This
+ * hook may be called multiple times during a single execve; and in each
+ * pass set_creds is called first.
+ * @bprm contains the linux_binprm structure.
+ * Return 0 if the hook is successful and permission is granted.
+ * @bprm_committing_creds:
+ * Prepare to install the new security attributes of a process being
+ * transformed by an execve operation, based on the old credentials
+ * pointed to by @current->cred and the information set in @bprm->cred by
+ * the bprm_set_creds hook. @bprm points to the linux_binprm structure.
+ * This hook is a good place to perform state changes on the process such
+ * as closing open file descriptors to which access will no longer be
+ * granted when the attributes are changed. This is called immediately
+ * before commit_creds().
+ * @bprm_committed_creds:
+ * Tidy up after the installation of the new security attributes of a
+ * process being transformed by an execve operation. The new credentials
+ * have, by this point, been set to @current->cred. @bprm points to the
+ * linux_binprm structure. This hook is a good place to perform state
+ * changes on the process such as clearing out non-inheritable signal
+ * state. This is called immediately after commit_creds().
+ * @bprm_secureexec:
+ * Return a boolean value (0 or 1) indicating whether a "secure exec"
+ * is required. The flag is passed in the auxiliary table
+ * on the initial stack to the ELF interpreter to indicate whether libc
+ * should enable secure mode.
+ * @bprm contains the linux_binprm structure.
+ *
+ * Security hooks for filesystem operations.
+ *
+ * @sb_alloc_security:
+ * Allocate and attach a security structure to the sb->s_security field.
+ * The s_security field is initialized to NULL when the structure is
+ * allocated.
+ * @sb contains the super_block structure to be modified.
+ * Return 0 if operation was successful.
+ * @sb_free_security:
+ * Deallocate and clear the sb->s_security field.
+ * @sb contains the super_block structure to be modified.
+ * @sb_statfs:
+ * Check permission before obtaining filesystem statistics for the @mnt
+ * mountpoint.
+ * @dentry is a handle on the superblock for the filesystem.
+ * Return 0 if permission is granted.
+ * @sb_mount:
+ * Check permission before an object specified by @dev_name is mounted on
+ * the mount point named by @nd. For an ordinary mount, @dev_name
+ * identifies a device if the file system type requires a device. For a
+ * remount (@flags & MS_REMOUNT), @dev_name is irrelevant. For a
+ * loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
+ * pathname of the object being mounted.
+ * @dev_name contains the name for object being mounted.
+ * @path contains the path for mount point object.
+ * @type contains the filesystem type.
+ * @flags contains the mount flags.
+ * @data contains the filesystem-specific data.
+ * Return 0 if permission is granted.
+ * @sb_copy_data:
+ * Allow mount option data to be copied prior to parsing by the filesystem,
+ * so that the security module can extract security-specific mount
+ * options cleanly (a filesystem may modify the data e.g. with strsep()).
+ * This also allows the original mount data to be stripped of security-
+ * specific options to avoid having to make filesystems aware of them.
+ * @type the type of filesystem being mounted.
+ * @orig the original mount data copied from userspace.
+ * @copy copied data which will be passed to the security module.
+ * Returns 0 if the copy was successful.
+ * @sb_remount:
+ * Extracts security system specific mount options and verifies no changes
+ * are being made to those options.
+ * @sb superblock being remounted
+ * @data contains the filesystem-specific data.
+ * Return 0 if permission is granted.
+ * @sb_umount:
+ * Check permission before the @mnt file system is unmounted.
+ * @mnt contains the mounted file system.
+ * @flags contains the unmount flags, e.g. MNT_FORCE.
+ * Return 0 if permission is granted.
+ * @sb_pivotroot:
+ * Check permission before pivoting the root filesystem.
+ * @old_path contains the path for the new location of the current root (put_old).
+ * @new_path contains the path for the new root (new_root).
+ * Return 0 if permission is granted.
+ * @sb_set_mnt_opts:
+ * Set the security relevant mount options used for a superblock
+ * @sb the superblock to set security mount options for
+ * @opts binary data structure containing all lsm mount data
+ * @sb_clone_mnt_opts:

+ * many other operations).
+ * Caveat: Although this hook can be used to revalidate permissions for

+ * Check permissions for a mmap operation at @addr.
+ * @addr contains virtual address that will be used for the operation.

+ * Check permission for the file owner @fown to send SIGIO or SIGURG to the
+ * process @tsk. Note that this hook is sometimes called from interrupt.
+ * Note that the fown_struct, @fown, is never outside the context of a

+ * if a writer is in progress by detecting change in sequence number.
+ * Writers do not wait for a sequence reader.
+ * 2. Locking readers which will wait if a writer or another locking reader
+ * is in progress. A locking reader in progress will also block a writer
+ * from going forward. Unlike the regular rwlock, the read lock here is
+ * exclusive so that only one locking reader can get it.
+ *
+ * This is not as cache friendly as brlock. Also, this may not work well
+ * for data that contains pointers, because any writer could
+ * invalidate a pointer that a reader was following.

+ * A seqno_fence is a dma_fence which can complete in software when
+ * enable_signaling is called, but it also completes when
+ * (s32)((sync_buf)[seqno_ofs] - seqno) >= 0 is true
+ *
+ * The seqno_fence will take a refcount on the sync_buf until it's
+ * destroyed, but actual lifetime of sync_buf may be longer if one of the
+ * callers take a reference to it.
+ *
+ * Certain hardware have instructions to insert this type of wait condition
+ * in the command stream, so no intervention from software would be needed.
+ * This type of fence can be destroyed before completed, however a reference
+ * on the sync_buf dma-buf can be taken. It is encouraged to re-use the same
+ * dma-buf for sync_buf, since mapping or unmapping the sync_buf to the
+ * device's vm can be expensive.
+ *
+ * It is recommended for creators of seqno_fence to call fence_signal
+ * before destruction. This will prevent possible issues from wraparound at
+ * time of issue vs time of check, since users can check fence_is_signaled
+ * before submitting instructions for the hardware to wait on the fence.
+ * However, when ops.enable_signaling is not called, it doesn't have to be
+ * done as soon as possible, just before there's any real danger of seqno

+ * In POSIX a signal is sent either to a specific thread (Linux task)

+ * from being delivered until later. When the signal is delivered,
+ * either it's caught or ignored by a user handler or it has a default
+ * effect that applies to the whole thread group (POSIX process).
+ *
+ * The possible effects an unblocked signal set to SIG_DFL can have are:
+ * ignore - Nothing Happens
+ * terminate - kill the process, i.e. all threads in the group,
+ * similar to exit_group. The group leader (only) reports
+ * WIFSIGNALED status to its parent.
+ * coredump - write a core dump file describing all threads using
+ * the same mm and then kill all those threads
+ * stop - stop all the threads in the group, i.e. TASK_STOPPED state
+ *
+ * SIGKILL and SIGSTOP cannot be caught, blocked, or ignored.
+ * Other signals when not blocked and set to SIG_DFL behaves as follows.
+ * The job control signals also have other special effects.

+ * +--------------------+------------------+
+ * | POSIX signal | default action |
+ * +--------------------+------------------+
+ * | SIGHUP | terminate |

+ *
+ * (+) For SIGKILL and SIGSTOP the action is "always", not just "default".
+ * (*) Special job control effects:

+ * (any of those marked with "stop(*)"). This happens regardless of blocking,
+ * catching, or ignoring SIGCONT. When any stop signal is sent, it clears
+ * any pending/queued SIGCONT signals; this happens regardless of blocking,
+ * catching, or ignored the stop signal, though (except for SIGSTOP) the
+ * default action of stopping the process may happen later or never.

+/* A. Checksumming of received packets by device.
+ *
+ * CHECKSUM_NONE:
+ *
+ * Device failed to checksum this packet e.g. due to lack of capabilities.
+ * The packet contains full (though not verified) checksum in packet but
+ * not in skb->csum. Thus, skb->csum is undefined in this case.
+ *
+ * CHECKSUM_UNNECESSARY:
+ *
+ * The hardware you're dealing with doesn't calculate the full checksum
+ * (as in CHECKSUM_COMPLETE), but it does parse headers and verify checksums
+ * for specific protocols. For such packets it will set CHECKSUM_UNNECESSARY
+ * if their checksums are okay. skb->csum is still undefined in this case
+ * though. It is a bad option, but, unfortunately, nowadays most vendors do
+ * this. Apparently with the secret goal to sell you new devices, when you
+ * will add new protocol to your host, f.e. IPv6 8)
+ *
+ * CHECKSUM_UNNECESSARY is applicable to following protocols:
+ * TCP: IPv6 and IPv4.
+ * UDP: IPv4 and IPv6. A device may apply CHECKSUM_UNNECESSARY to a
+ * zero UDP checksum for either IPv4 or IPv6, the networking stack
+ * may perform further validation in this case.
+ * GRE: only if the checksum is present in the header.
+ * SCTP: indicates the CRC in SCTP header has been validated.
+ *
+ * skb->csum_level indicates the number of consecutive checksums found in
+ * the packet minus one that have been verified as CHECKSUM_UNNECESSARY.
+ * For instance if a device receives an IPv6->UDP->GRE->IPv4->TCP packet
+ * and a device is able to verify the checksums for UDP (possibly zero),
+ * GRE (checksum flag is set), and TCP-- skb->csum_level would be set to
+ * two. If the device were only able to verify the UDP checksum and not
+ * GRE, either because it doesn't support GRE checksum of because GRE
+ * checksum is bad, skb->csum_level would be set to zero (TCP checksum is
+ * not considered in this case).
+ *
+ * CHECKSUM_COMPLETE:
+ *
+ * This is the most generic way. The device supplied checksum of the _whole_
+ * packet as seen by netif_rx() and fills out in skb->csum. Meaning, the
+ * hardware doesn't need to parse L3/L4 headers to implement this.
+ *
+ * Note: Even if device supports only some protocols, but is able to produce
+ * skb->csum, it MUST use CHECKSUM_COMPLETE, not CHECKSUM_UNNECESSARY.
+ *
+ * CHECKSUM_PARTIAL:
+ *
+ * A checksum is set up to be offloaded to a device as described in the
+ * output description for CHECKSUM_PARTIAL. This may occur on a packet
+ * received directly from another Linux OS, e.g., a virtualized Linux kernel
+ * on the same host, or it may be set in the input path in GRO or remote
+ * checksum offload. For the purposes of checksum verification, the checksum
+ * referred to by skb->csum_start + skb->csum_offset and any preceding
+ * checksums in the packet are considered verified. Any checksums in the
+ * packet that are after the checksum being offloaded are not considered to
+ * be verified.
+ *
+ * B. Checksumming on output.
+ *
+ * CHECKSUM_NONE:
+ *
+ * The skb was already checksummed by the protocol, or a checksum is not
+ * required.
+ *
+ * CHECKSUM_PARTIAL:
+ *
+ * The device is required to checksum the packet as seen by hard_start_xmit()
+ * from skb->csum_start up to the end, and to record/write the checksum at
+ * offset skb->csum_start + skb->csum_offset.
+ *
+ * The device must show its capabilities in dev->features, set up at device
+ * setup time, e.g. netdev_features.h:
+ *
+ * NETIF_F_HW_CSUM - It's a clever device, it's able to checksum everything.
+ * NETIF_F_IP_CSUM - Device is dumb, it's able to checksum only TCP/UDP over
+ * IPv4. Sigh. Vendors like this way for an unknown reason.
+ * Though, see comment above about CHECKSUM_UNNECESSARY. 8)
+ * NETIF_F_IPV6_CSUM - About as dumb as the last one but does IPv6 instead.
+ * NETIF_F_... - Well, you get the picture.
+ *
+ * CHECKSUM_UNNECESSARY:
+ *
+ * Normally, the device will do per protocol specific checksumming. Protocol
+ * implementations that do not want the NIC to perform the checksum
+ * calculation should use this flag in their outgoing skbs.
+ *
+ * NETIF_F_FCOE_CRC - This indicates that the device can do FCoE FC CRC
+ * offload. Correspondingly, the FCoE protocol driver
+ * stack should use CHECKSUM_UNNECESSARY.
+ *
+ * Any questions? No questions, good. --ANK

+ * kmalloc - allocate memory
+ * @size: how many bytes of memory are required.
+ * @flags: the type of memory to allocate.
+ *
+ * kmalloc is the normal method of allocating memory
+ * for objects smaller than page size in the kernel.
+ *
+ * The @flags argument may be one of:
+ *
+ * %GFP_USER - Allocate memory on behalf of user. May sleep.
+ *
+ * %GFP_KERNEL - Allocate normal kernel ram. May sleep.
+ *
+ * %GFP_ATOMIC - Allocation will not sleep. May use emergency pools.
+ * For example, use this inside interrupt handlers.
+ *
+ * %GFP_HIGHUSER - Allocate pages from high memory.
+ *
+ * %GFP_NOIO - Do not do any I/O at all while trying to get memory.
+ *
+ * %GFP_NOFS - Do not make any fs calls while trying to get memory.
+ *
+ * %GFP_NOWAIT - Allocation will not sleep.
+ *
+ * %__GFP_THISNODE - Allocate node-local memory only.
+ *
+ * %GFP_DMA - Allocation suitable for DMA.
+ * Should only be used for kmalloc() caches. Otherwise, use a
+ * slab created with SLAB_DMA.
+ *
+ * Also it is possible to set different flags by OR'ing
+ * in one or more of the following additional @flags:
+ *
+ * %__GFP_COLD - Request cache-cold pages instead of
+ * trying to return cache-warm pages.
+ *
+ * %__GFP_HIGH - This allocation has high priority and may use emergency pools.
+ *
+ * %__GFP_NOFAIL - Indicate that this allocation is in no way allowed to fail

+ * @rx_dma: DMA address of rx_buf, if @spi_message.is_dma_mapped
+ * @tx_nbits: number of bits used for writing. If 0 the default
+ * (SPI_NBITS_SINGLE) is used.
+ * @rx_nbits: number of bits used for reading. If 0 the default
+ * (SPI_NBITS_SINGLE) is used.
+ * @len: size of rx and tx buffers (in bytes)
+ * @speed_hz: Select a speed other than the device default for this
+ * transfer. If 0 the default (from @spi_device) is used.
+ * @bits_per_word: select a bits_per_word other than the device default
+ * for this transfer. If 0 the default (from @spi_device) is used.
+ * @cs_change: affects chipselect after this transfer completes
+ * @delay_usecs: microseconds to delay after this transfer before
+ * (optionally) changing the chipselect status, then starting
+ * the next transfer or completing this @spi_message.
+ * @transfer_list: transfers are sequenced through @spi_message.transfers
+ * @tx_sg: Scatterlist for transmit, currently not for client use
+ * @rx_sg: Scatterlist for receive, currently not for client use
+ *
+ * SPI transfers always write the same number of bytes as they read.
+ * Protocol drivers should always provide @rx_buf and/or @tx_buf.
+ * In some cases, they may also want to provide DMA addresses for
+ * the data being transferred; that may reduce overhead, when the
+ * underlying driver uses dma.
+ *
+ * If the transmit buffer is null, zeroes will be shifted out
+ * while filling @rx_buf. If the receive buffer is null, the data
+ * shifted in will be discarded. Only "len" bytes shift out (or in).
+ * It's an error to try to shift out a partial word. (For example, by
+ * shifting out three bytes with word size of sixteen or twenty bits;
+ * the former uses two bytes per word, the latter uses four bytes.)
+ *
+ * In-memory data values are always in native CPU byte order, translated
+ * from the wire byte order (big-endian except with SPI_LSB_FIRST). So
+ * for example when bits_per_word is sixteen, buffers are 2N bytes long
+ * (@len = 2N) and hold N sixteen bit words in CPU byte order.
+ *
+ * When the word size of the SPI transfer is not a power-of-two multiple
+ * of eight bits, those in-memory words include extra bits. In-memory
+ * words are always seen by protocol drivers as right-justified, so the
+ * undefined (rx) or unused (tx) bits are always the most significant bits.
+ *
+ * All SPI transfers start with the relevant chipselect active. Normally
+ * it stays selected until after the last transfer in a message. Drivers
+ * can affect the chipselect signal using cs_change.
+ *
+ * (i) If the transfer isn't the last one in the message, this flag is
+ * used to make the chipselect briefly go inactive in the middle of the
+ * message. Toggling chipselect in this way may be needed to terminate
+ * a chip command, letting a single spi_message perform all of group of
+ * chip transactions together.
+ *
+ * (ii) When the transfer is the last one in the message, the chip may
+ * stay selected until the next transfer. On multi-device SPI busses
+ * with nothing blocking messages going to other devices, this is just
+ * a performance hint; starting a message to another device deselects
+ * this one. But in other cases, this can be used to ensure correctness.
+ * Some devices need protocol transactions to be built from a series of
+ * spi_message submissions, where the content of one message is determined
+ * by the results of previous messages and where the whole transaction
+ * ends when the chipselect goes intactive.
+ *
+ * When SPI can transfer in 1x,2x or 4x. It can get this transfer information
+ * from device through @tx_nbits and @rx_nbits. In Bi-direction, these
+ * two should both be set. User can set transfer mode with SPI_NBITS_SINGLE(1x)
+ * SPI_NBITS_DUAL(2x) and SPI_NBITS_QUAD(4x) to support these three transfer.
+ *
+ * The code that submits an spi_message (and its spi_transfers)
+ * to the lower layers is responsible for managing its memory.
+ * Zero-initialize every field you don't set up explicitly, to
+ * insulate against future API updates. After you submit a message
+ * and its transfers, ignore them until its completion callback.

+ * The External Interface core supports a total of three external chip selects
+ * supporting external interfaces. One of the external chip selects is
+ * used for Flash, one is used for PCMCIA, and the other may be

+ * The external interface core also contains 2 on-chip 16550 UARTs, clock
+ * frequency control, a watchdog interrupt timer, and a GPIO interface.

+ * RPC client per-operation statistics provide latency and retry
+ * information about each type of RPC procedure in a given RPC program.
+ * These statistics are not for detailed problem diagnosis, but simply
+ * to indicate whether the problem is local or remote.
+ *
+ * These counters are not meant to be human-readable, but are meant to be
+ * integrated into system monitoring tools such as "sar" and "iostat". As
+ * such, the counters are sampled by the tools over time, and are never
+ * zeroed after a file system is mounted. Moving averages can be computed
+ * by the tools by taking the difference between two instantaneous samples
+ * and dividing that by the time between the samples.
+ *
+ * The counters are maintained in a single array per RPC client, indexed
+ * by procedure number. There is no need to maintain separate counter
+ * arrays per-CPU because these counters are always modified behind locks.

+ * For TCP over IPv4 and for UDP over IPv4, the format of r_addr is the
+ * US-ASCII string:
+ *
+ * h1.h2.h3.h4.p1.p2
+ *
+ * The prefix, "h1.h2.h3.h4", is the standard textual form for
+ * representing an IPv4 address, which is always four octets long.
+ * Assuming big-endian ordering, h1, h2, h3, and h4, are respectively,
+ * the first through fourth octets each converted to ASCII-decimal.
+ * Assuming big-endian ordering, p1 and p2 are, respectively, the first
+ * and second octets each converted to ASCII-decimal. For example, if a
+ * host, in big-endian order, has an address of 0x0A010307 and there is
+ * a service listening on, in big endian order, port 0x020F (decimal
+ * 527), then the complete universal address is "10.1.3.7.2.15".
+ *
+ * ...
+ *
+ * For TCP over IPv6 and for UDP over IPv6, the format of r_addr is the
+ * US-ASCII string:
+ *
+ * x1:x2:x3:x4:x5:x6:x7:x8.p1.p2
+ *
+ * The suffix "p1.p2" is the service port, and is computed the same way
+ * as with universal addresses for TCP and UDP over IPv4. The prefix,
+ * "x1:x2:x3:x4:x5:x6:x7:x8", is the standard textual form for
+ * representing an IPv6 address as defined in Section 2.2 of [RFC2373].

+/**
+ * struct platform_suspend_ops - Callbacks for managing platform dependent
+ * system sleep states.
+ *
+ * @valid: Callback to determine if given system sleep state is supported by
+ * the platform.
+ * Valid (ie. supported) states are advertised in /sys/power/state. Note
+ * that it still may be impossible to enter given system sleep state if the
+ * conditions aren't right.
+ * There is the %suspend_valid_only_mem function available that can be
+ * assigned to this if the platform only supports mem sleep.
+ *
+ * @begin: Initialise a transition to given system sleep state.
+ * @begin() is executed right prior to suspending devices. The information
+ * conveyed to the platform code by @begin() should be disregarded by it as
+ * soon as @end() is executed. If @begin() fails (ie. returns nonzero),
+ * @prepare(), @enter() and @finish() will not be called by the PM core.
+ * This callback is optional. However, if it is implemented, the argument
+ * passed to @enter() is redundant and should be ignored.
+ *
+ * @prepare: Prepare the platform for entering the system sleep state indicated
+ * by @begin().
+ * @prepare() is called right after devices have been suspended (ie. the
+ * appropriate .suspend() method has been executed for each device) and
+ * before device drivers' late suspend callbacks are executed. It returns
+ * 0 on success or a negative error code otherwise, in which case the
+ * system cannot enter the desired sleep state (@prepare_late(), @enter(),
+ * and @wake() will not be called in that case).
+ *
+ * @prepare_late: Finish preparing the platform for entering the system sleep
+ * state indicated by @begin().
+ * @prepare_late is called before disabling nonboot CPUs and after
+ * device drivers' late suspend callbacks have been executed. It returns
+ * 0 on success or a negative error code otherwise, in which case the
+ * system cannot enter the desired sleep state (@enter() will not be
+ * executed).
+ *
+ * @enter: Enter the system sleep state indicated by @begin() or represented by
+ * the argument if @begin() is not implemented.
+ * This callback is mandatory. It returns 0 on success or a negative
+ * error code otherwise, in which case the system cannot enter the desired
+ * sleep state.
+ *
+ * @wake: Called when the system has just left a sleep state, right after
+ * the nonboot CPUs have been enabled and before device drivers' early
+ * resume callbacks are executed.
+ * This callback is optional, but should be implemented by the platforms
+ * that implement @prepare_late(). If implemented, it is always called
+ * after @prepare_late and @enter(), even if one of them fails.
+ *
+ * @finish: Finish wake-up of the platform.
+ * @finish is called right prior to calling device drivers' regular suspend
+ * callbacks.
+ * This callback is optional, but should be implemented by the platforms
+ * that implement @prepare(). If implemented, it is always called after
+ * @enter() and @wake(), even if any of them fails. It is executed after
+ * a failing @prepare.
+ *
+ * @suspend_again: Returns whether the system should suspend again (true) or
+ * not (false). If the platform wants to poll sensors or execute some
+ * code during suspended without invoking userspace and most of devices,
+ * suspend_again callback is the place assuming that periodic-wakeup or
+ * alarm-wakeup is already setup. This allows to execute some codes while
+ * being kept suspended in the view of userland and devices.
+ *
+ * @end: Called by the PM core right after resuming devices, to indicate to
+ * the platform that the system has returned to the working state or
+ * the transition to the sleep state has been aborted.
+ * This callback is optional, but should be implemented by the platforms
+ * that implement @begin(). Accordingly, platforms implementing @begin()
+ * should also provide a @end() which cleans up transitions aborted before
+ * @enter().
+ *
+ * @recover: Recover the platform from a suspend failure.
+ * Called by the PM core if the suspending of devices fails.
+ * This callback is optional and should only be implemented by platforms
+ * which require special recovery actions in that situation.

+ * This file defines hook entry points called by core code where

+ *
+ * Each function here typically has only one call site, so it is ok
+ * to have some nontrivial tracehook_*() inlines. In all cases, the
+ * fast path when no tracing is enabled should be very short.
+ *
+ * The purpose of this file and the tracehook_* layer is to consolidate
+ * the interface that the kernel core and arch code uses to enable any
+ * user debugging or tracing facility (such as ptrace). The interfaces
+ * here are carefully documented so that maintainers of core and arch
+ * code do not need to think about the implementation details of the
+ * tracing facilities. Likewise, maintainers of the tracing code do not
+ * need to understand all the calling core or arch code in detail, just

+ * This structure defines the interface between the low-level tty

+ * defined; unless noted otherwise, they are optional, and can be
+ * filled in with a null pointer.
+ *
+ * struct tty_struct * (*lookup)(struct tty_driver *self, int idx)
+ *
+ * Return the tty device corresponding to idx, NULL if there is not
+ * one currently in use and an ERR_PTR value on error. Called under
+ * tty_mutex (for now!)
+ *
+ * Optional method. Default behaviour is to use the ttys array
+ *
+ * int (*install)(struct tty_driver *self, struct tty_struct *tty)
+ *
+ * Install a new tty into the tty driver internal tables. Used in
+ * conjunction with lookup and remove methods.
+ *
+ * Optional method. Default behaviour is to use the ttys array
+ *
+ * void (*remove)(struct tty_driver *self, struct tty_struct *tty)
+ *
+ * Remove a closed tty from the tty driver internal tables. Used in
+ * conjunction with lookup and remove methods.
+ *
+ * Optional method. Default behaviour is to use the ttys array
+ *
+ * int (*open)(struct tty_struct * tty, struct file * filp);
+ *
+ * This routine is called when a particular tty device is opened.
+ * This routine is mandatory; if this routine is not filled in,
+ * the attempted open will fail with ENODEV.
+ *
+ * Required method. Called with tty lock held.
+ *
+ * void (*close)(struct tty_struct * tty, struct file * filp);
+ *
+ * This routine is called when a particular tty device is closed.
+ * Note: called even if the corresponding open() failed.
+ *
+ * Required method. Called with tty lock held.
+ *
+ * void (*shutdown)(struct tty_struct * tty);
+ *
+ * This routine is called under the tty lock when a particular tty device
+ * is closed for the last time. It executes before the tty resources
+ * are freed so may execute while another function holds a tty kref.
+ *
+ * void (*cleanup)(struct tty_struct * tty);
+ *
+ * This routine is called asynchronously when a particular tty device
+ * is closed for the last time freeing up the resources. This is
+ * actually the second part of shutdown for routines that might sleep.
+ *
+ *
+ * int (*write)(struct tty_struct * tty,
+ * const unsigned char *buf, int count);
+ *
+ * This routine is called by the kernel to write a series of
+ * characters to the tty device. The characters may come from
+ * user space or kernel space. This routine will return the
+ * number of characters actually accepted for writing.
+ *
+ * Optional: Required for writable devices.
+ *
+ * int (*put_char)(struct tty_struct *tty, unsigned char ch);
+ *
+ * This routine is called by the kernel to write a single
+ * character to the tty device. If the kernel uses this routine,
+ * it must call the flush_chars() routine (if defined) when it is
+ * done stuffing characters into the driver. If there is no room
+ * in the queue, the character is ignored.
+ *
+ * Optional: Kernel will use the write method if not provided.
+ *
+ * Note: Do not call this function directly, call tty_put_char
+ *
+ * void (*flush_chars)(struct tty_struct *tty);
+ *
+ * This routine is called by the kernel after it has written a
+ * series of characters to the tty device using put_char().
+ *
+ * Optional:
+ *
+ * Note: Do not call this function directly, call tty_driver_flush_chars
+ *
+ * int (*write_room)(struct tty_struct *tty);
+ *
+ * This routine returns the numbers of characters the tty driver
+ * will accept for queuing to be written. This number is subject
+ * to change as output buffers get emptied, or if the output flow
+ * control is acted.
+ *
+ * Required if write method is provided else not needed.
+ *
+ * Note: Do not call this function directly, call tty_write_room
+ *
+ * int (*ioctl)(struct tty_struct *tty, unsigned int cmd, unsigned long arg);
+ *
+ * This routine allows the tty driver to implement
+ * device-specific ioctls. If the ioctl number passed in cmd
+ * is not recognized by the driver, it should return ENOIOCTLCMD.
+ *
+ * Optional
+ *
+ * long (*compat_ioctl)(struct tty_struct *tty,,
+ * unsigned int cmd, unsigned long arg);
+ *
+ * implement ioctl processing for 32 bit process on 64 bit system
+ *
+ * Optional
+ *
+ * void (*set_termios)(struct tty_struct *tty, struct ktermios * old);
+ *
+ * This routine allows the tty driver to be notified when
+ * device's termios settings have changed.
+ *
+ * Optional: Called under the termios lock
+ *
+ *
+ * void (*set_ldisc)(struct tty_struct *tty);
+ *
+ * This routine allows the tty driver to be notified when the
+ * device's termios settings have changed.
+ *
+ * Optional: Called under BKL (currently)
+ *
+ * void (*throttle)(struct tty_struct * tty);
+ *
+ * This routine notifies the tty driver that input buffers for
+ * the line discipline are close to full, and it should somehow
+ * signal that no more characters should be sent to the tty.
+ *
+ * Optional: Always invoke via tty_throttle(), called under the
+ * termios lock.
+ *
+ * void (*unthrottle)(struct tty_struct * tty);
+ *
+ * This routine notifies the tty drivers that it should signals
+ * that characters can now be sent to the tty without fear of
+ * overrunning the input buffers of the line disciplines.
+ *
+ * Optional: Always invoke via tty_unthrottle(), called under the
+ * termios lock.
+ *
+ * void (*stop)(struct tty_struct *tty);
+ *
+ * This routine notifies the tty driver that it should stop
+ * outputting characters to the tty device.
+ *
+ * Called with ->flow_lock held. Serialized with start() method.
+ *
+ * Optional:
+ *
+ * Note: Call stop_tty not this method.
+ *
+ * void (*start)(struct tty_struct *tty);
+ *
+ * This routine notifies the tty driver that it resume sending
+ * characters to the tty device.
+ *
+ * Called with ->flow_lock held. Serialized with stop() method.
+ *
+ * Optional:
+ *
+ * Note: Call start_tty not this method.
+ *
+ * void (*hangup)(struct tty_struct *tty);
+ *
+ * This routine notifies the tty driver that it should hang up the
+ * tty device.
+ *
+ * Optional:
+ *
+ * Called with tty lock held.
+ *
+ * int (*break_ctl)(struct tty_struct *tty, int state);
+ *
+ * This optional routine requests the tty driver to turn on or
+ * off BREAK status on the RS-232 port. If state is -1,
+ * then the BREAK status should be turned on; if state is 0, then
+ * BREAK should be turned off.
+ *
+ * If this routine is implemented, the high-level tty driver will
+ * handle the following ioctls: TCSBRK, TCSBRKP, TIOCSBRK,
+ * TIOCCBRK.
+ *
+ * If the driver sets TTY_DRIVER_HARDWARE_BREAK then the interface
+ * will also be called with actual times and the hardware is expected
+ * to do the delay work itself. 0 and -1 are still used for on/off.
+ *
+ * Optional: Required for TCSBRK/BRKP/etc handling.
+ *
+ * void (*wait_until_sent)(struct tty_struct *tty, int timeout);
+ *
+ * This routine waits until the device has written out all of the
+ * characters in its transmitter FIFO.
+ *
+ * Optional: If not provided the device is assumed to have no FIFO
+ *
+ * Note: Usually correct to call tty_wait_until_sent
+ *
+ * void (*send_xchar)(struct tty_struct *tty, char ch);
+ *
+ * This routine is used to send a high-priority XON/XOFF
+ * character to the device.
+ *
+ * Optional: If not provided then the write method is called under
+ * the atomic write lock to keep it serialized with the ldisc.
+ *
+ * int (*resize)(struct tty_struct *tty, struct winsize *ws)
+ *
+ * Called when a termios request is issued which changes the
+ * requested terminal geometry.
+ *
+ * Optional: the default action is to update the termios structure
+ * without error. This is usually the correct behaviour. Drivers should
+ * not force errors here if they are not resizable objects (eg a serial
+ * line). See tty_do_resize() if you need to wrap the standard method
+ * in your own logic - the usual case.
+ *
+ * void (*set_termiox)(struct tty_struct *tty, struct termiox *new);
+ *
+ * Called when the device receives a termiox based ioctl. Passes down
+ * the requested data from user space. This method will not be invoked
+ * unless the tty also has a valid tty->termiox pointer.
+ *
+ * Optional: Called under the termios lock
+ *
+ * int (*get_icount)(struct tty_struct *tty, struct serial_icounter *icount);
+ *
+ * Called when the device receives a TIOCGICOUNT ioctl. Passed a kernel
+ * structure to complete. This method is optional and will only be called
+ * if provided (otherwise EINVAL will be returned).

+ * void (*close)(struct tty_struct *);
+ *
+ * This function is called when the line discipline is being
+ * shutdown, either because the tty is being closed or because
+ * the tty is being changed to use a new line discipline
+ *
+ * void (*flush_buffer)(struct tty_struct *tty);
+ *
+ * This function instructs the line discipline to clear its
+ * buffers of any input characters it may have queued to be
+ * delivered to the user mode process.
+ *
+ * ssize_t (*chars_in_buffer)(struct tty_struct *tty);
+ *
+ * This function returns the number of input characters the line
+ * discipline may have queued up to be delivered to the user mode
+ * process.
+ *
+ * ssize_t (*read)(struct tty_struct * tty, struct file * file,
+ * unsigned char * buf, size_t nr);
+ *
+ * This function is called when the user requests to read from
+ * the tty. The line discipline will return whatever characters
+ * it has buffered up for the user. If this function is not
+ * defined, the user will receive an EIO error.
+ *
+ * ssize_t (*write)(struct tty_struct * tty, struct file * file,
+ * const unsigned char * buf, size_t nr);
+ *
+ * This function is called when the user requests to write to the

+ * low-level tty device for transmission, optionally performing
+ * some processing on the characters first. If this function is
+ * not defined, the user will receive an EIO error.
+ *
+ * int (*ioctl)(struct tty_struct * tty, struct file * file,
+ * unsigned int cmd, unsigned long arg);
+ *
+ * This function is called when the user requests an ioctl which
+ * is not handled by the tty layer or the low-level tty driver.
+ * It is intended for ioctls which affect line discpline
+ * operation. Note that the search order for ioctls is (1) tty
+ * layer, (2) tty low-level driver, (3) line discpline. So a
+ * low-level driver can "grab" an ioctl request before the line
+ * discpline has a chance to see it.

+ * This function notifies the line discpline that a change has
+ * been made to the termios structure.
+ *
+ * int (*poll)(struct tty_struct * tty, struct file * file,
+ * poll_table *wait);
+ *
+ * This function is called when a user attempts to select/poll on a
+ * tty device. It is solely the responsibility of the line
+ * discipline to handle poll requests.
+ *
+ * void (*receive_buf)(struct tty_struct *, const unsigned char *cp,
+ * char *fp, int count);
+ *
+ * This function is called by the low-level tty driver to send
+ * characters received by the hardware to the line discpline for
+ * processing. <cp> is a pointer to the buffer of input
+ * character received by the device. <fp> is a pointer to a
+ * pointer of flag bytes which indicate whether a character was
+ * received with a parity error, etc. <fp> may be NULL to indicate
+ * all data received is TTY_NORMAL.
+ *
+ * void (*write_wakeup)(struct tty_struct *);
+ *
+ * This function is called by the low-level tty driver to signal
+ * that line discpline should try to send more characters to the
+ * low-level driver for transmission. If the line discpline does
+ * not have any more data to send, it can just return. If the line
+ * discipline does have some data to send, please arise a tasklet
+ * or workqueue to do the real data transfer. Do not send data in
+ * this hook, it may leads to a deadlock.
+ *
+ * int (*hangup)(struct tty_struct *)
+ *
+ * Called on a hangup. Tells the discipline that it should
+ * cease I/O to the tty driver. Can sleep. The driver should
+ * seek to perform this action quickly but should wait until
+ * any pending driver I/O is completed.
+ *
+ * void (*fasync)(struct tty_struct *, int on)
+ *
+ * Notify line discipline when signal-driven I/O is enabled or
+ * disabled.
+ *
+ * void (*dcd_change)(struct tty_struct *tty, unsigned int status)
+ *
+ * Tells the discipline that the DCD pin has changed its status.
+ * Used exclusively by the N_PPS (Pulse-Per-Second) line discipline.

+ * To properly implement 64bits network statistics on 32bit and 64bit hosts,
+ * we provide a synchronization point, that is a noop on 64bit or UP kernels.
+ *
+ * Key points :
+ * 1) Use a seqcount on SMP 32bits, with low overhead.
+ * 2) Whole thing is a noop on 64bit arches or UP kernels.
+ * 3) Write side must ensure mutual exclusion or one seqcount update could
+ * be lost, thus blocking readers forever.
+ * If this synchronization point is not a mutex, but a spinlock or
+ * spinlock_bh() or disable_bh() :
+ * 3.1) Write side should not sleep.
+ * 3.2) Write side should not allow preemption.
+ * 3.3) If applicable, interrupts should be disabled.
+ *
+ * 4) If reader fetches several counters, there is no guarantee the whole values
+ * are consistent (remember point 1) : this is a noop on 64bit arches anyway)
+ *
+ * 5) readers are allowed to sleep or be preempted/interrupted : They perform
+ * pure reads. But if they have to fetch many values, it's better to not allow
+ * preemptions/interruptions to avoid many retries.
+ *
+ * 6) If counter might be written by an interrupt, readers should block interrupts.
+ * (On UP, there is no seqcount_t protection, a reader allowing interrupts could
+ * read partial values)
+ *
+ * 7) For irq and softirq uses, readers can use u64_stats_fetch_begin_irq() and
+ * u64_stats_fetch_retry_irq() helpers
+ *
+ * Usage :
+ *
+ * Stats producer (writer) should use following template granted it already got
+ * an exclusive access to counters (a lock is already taken, or per cpu
+ * data is used [in a non preemptable context])
+ *
+ * spin_lock_bh(...) or other synchronization to get exclusive access

+ * function of the driver, after it has been assigned a minor

+ *
+ * USB device drivers attach to interfaces on a physical device. Each
+ * interface encapsulates a single high level function, such as feeding
+ * an audio stream to a speaker or reporting a change in a volume control.
+ * Many USB devices only have one interface. The protocol used to talk to
+ * an interface's endpoints can be defined in a usb "class" specification,
+ * or by a product's vendor. The (default) control endpoint is part of
+ * every interface, but is never listed among the interface's descriptors.
+ *
+ * The driver that is bound to the interface can use standard driver model
+ * calls such as dev_get_drvdata() on the dev member of this structure.
+ *
+ * Each interface may have alternate settings. The initial configuration
+ * of a device sets altsetting 0, but the device driver can change
+ * that setting using usb_set_interface(). Alternate settings are often
+ * used to control the use of periodic endpoints, such as by having
+ * different endpoints use different amounts of reserved USB bandwidth.
+ * All standards-conformant USB devices that use isochronous endpoints
+ * will use them in non-default settings.
+ *
+ * The USB specification says that alternate setting numbers must run from
+ * 0 to one less than the total number of alternate settings. But some
+ * devices manage to mess this up, and the structures aren't necessarily
+ * stored in numerical order anyhow. Use usb_altnum_to_altsetting() to
+ * look up an alternate setting in the altsetting array based on its number.

+ * struct urb - USB Request Block
+ * @urb_list: For use by current owner of the URB.
+ * @anchor_list: membership in the list of an anchor
+ * @anchor: to anchor URBs to a common mooring
+ * @ep: Points to the endpoint's data structure. Will eventually
+ * replace @pipe.
+ * @pipe: Holds endpoint number, direction, type, and more.
+ * Create these values with the eight macros available;
+ * usb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is "ctrl"
+ * (control), "bulk", "int" (interrupt), or "iso" (isochronous).
+ * For example usb_sndbulkpipe() or usb_rcvintpipe(). Endpoint
+ * numbers range from zero to fifteen. Note that "in" endpoint two
+ * is a different endpoint (and pipe) from "out" endpoint two.
+ * The current configuration controls the existence, type, and
+ * maximum packet size of any given endpoint.
+ * @stream_id: the endpoint's stream ID for bulk streams
+ * @dev: Identifies the USB device to perform the request.
+ * @status: This is read in non-iso completion functions to get the
+ * status of the particular request. ISO requests only use it
+ * to tell whether the URB was unlinked; detailed status for
+ * each frame is in the fields of the iso_frame-desc.
+ * @transfer_flags: A variety of flags may be used to affect how URB
+ * submission, unlinking, or operation are handled. Different
+ * kinds of URB can use different flags.
+ * @transfer_buffer: This identifies the buffer to (or from) which the I/O
+ * request will be performed unless URB_NO_TRANSFER_DMA_MAP is set
+ * (however, do not leave garbage in transfer_buffer even then).
+ * This buffer must be suitable for DMA; allocate it with
+ * kmalloc() or equivalent. For transfers to "in" endpoints, contents
+ * of this buffer will be modified. This buffer is used for the data
+ * stage of control transfers.
+ * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP,
+ * the device driver is saying that it provided this DMA address,
+ * which the host controller driver should use in preference to the
+ * transfer_buffer.
+ * @sg: scatter gather buffer list, the buffer size of each element in
+ * the list (except the last) must be divisible by the endpoint's
+ * max packet size if no_sg_constraint isn't set in 'struct usb_bus'
+ * @num_mapped_sgs: (internal) number of mapped sg entries
+ * @num_sgs: number of entries in the sg list
+ * @transfer_buffer_length: How big is transfer_buffer. The transfer may
+ * be broken up into chunks according to the current maximum packet
+ * size for the endpoint, which is a function of the configuration
+ * and is encoded in the pipe. When the length is zero, neither
+ * transfer_buffer nor transfer_dma is used.
+ * @actual_length: This is read in non-iso completion functions, and
+ * it tells how many bytes (out of transfer_buffer_length) were
+ * transferred. It will normally be the same as requested, unless
+ * either an error was reported or a short read was performed.
+ * The URB_SHORT_NOT_OK transfer flag may be used to make such
+ * short reads be reported as errors.
+ * @setup_packet: Only used for control transfers, this points to eight bytes
+ * of setup data. Control transfers always start by sending this data
+ * to the device. Then transfer_buffer is read or written, if needed.
+ * @setup_dma: DMA pointer for the setup packet. The caller must not use
+ * this field; setup_packet must point to a valid buffer.
+ * @start_frame: Returns the initial frame for isochronous transfers.
+ * @number_of_packets: Lists the number of ISO transfer buffers.
+ * @interval: Specifies the polling interval for interrupt or isochronous
+ * transfers. The units are frames (milliseconds) for full and low
+ * speed devices, and microframes (1/8 millisecond) for highspeed
+ * and SuperSpeed devices.
+ * @error_count: Returns the number of ISO transfers that reported errors.
+ * @context: For use in completion functions. This normally points to
+ * request-specific driver context.
+ * @complete: Completion handler. This URB is passed as the parameter to the
+ * completion function. The completion function may then do what
+ * it likes with the URB, including resubmitting or freeing it.
+ * @iso_frame_desc: Used to provide arrays of ISO transfer buffers and to
+ * collect the transfer status for each buffer.
+ *
+ * This structure identifies USB transfer requests. URBs must be allocated by
+ * calling usb_alloc_urb() and freed with a call to usb_free_urb().
+ * Initialization may be done using various usb_fill_*_urb() functions. URBs
+ * are submitted using usb_submit_urb(), and pending requests may be canceled
+ * using usb_unlink_urb() or usb_kill_urb().
+ *
+ * Data Transfer Buffers:
+ *
+ * Normally drivers provide I/O buffers allocated with kmalloc() or otherwise
+ * taken from the general page pool. That is provided by transfer_buffer
+ * (control requests also use setup_packet), and host controller drivers
+ * perform a dma mapping (and unmapping) for each buffer transferred. Those
+ * mapping operations can be expensive on some platforms (perhaps using a dma
+ * bounce buffer or talking to an IOMMU),
+ * although they're cheap on commodity x86 and ppc hardware.
+ *
+ * Alternatively, drivers may pass the URB_NO_TRANSFER_DMA_MAP transfer flag,
+ * which tells the host controller driver that no such mapping is needed for
+ * the transfer_buffer since
+ * the device driver is DMA-aware. For example, a device driver might
+ * allocate a DMA buffer with usb_alloc_coherent() or call usb_buffer_map().
+ * When this transfer flag is provided, host controller drivers will
+ * attempt to use the dma address found in the transfer_dma
+ * field rather than determining a dma address themselves.
+ *
+ * Note that transfer_buffer must still be set if the controller
+ * does not support DMA (as indicated by bus.uses_dma) and when talking
+ * to root hub. If you have to trasfer between highmem zone and the device
+ * on such controller, create a bounce buffer or bail out with an error.
+ * If transfer_buffer cannot be set (is in highmem) and the controller is DMA
+ * capable, assign NULL to it, so that usbmon knows not to use the value.
+ * The setup_packet must always be set, so it cannot be located in highmem.
+ *
+ * Initialization:
+ *
+ * All URBs submitted must initialize the dev, pipe, transfer_flags (may be
+ * zero), and complete fields. All URBs must also initialize
+ * transfer_buffer and transfer_buffer_length. They may provide the
+ * URB_SHORT_NOT_OK transfer flag, indicating that short reads are
+ * to be treated as errors; that flag is invalid for write requests.
+ *
+ * Bulk URBs may
+ * use the URB_ZERO_PACKET transfer flag, indicating that bulk OUT transfers
+ * should always terminate with a short packet, even if it means adding an
+ * extra zero length packet.
+ *
+ * Control URBs must provide a valid pointer in the setup_packet field.
+ * Unlike the transfer_buffer, the setup_packet may not be mapped for DMA
+ * beforehand.
+ *
+ * Interrupt URBs must provide an interval, saying how often (in milliseconds
+ * or, for highspeed devices, 125 microsecond units)
+ * to poll for transfers. After the URB has been submitted, the interval
+ * field reflects how the transfer was actually scheduled.
+ * The polling interval may be more frequent than requested.
+ * For example, some controllers have a maximum interval of 32 milliseconds,
+ * while others support intervals of up to 1024 milliseconds.
+ * Isochronous URBs also have transfer intervals. (Note that for isochronous
+ * endpoints, as well as high speed interrupt endpoints, the encoding of
+ * the transfer interval in the endpoint descriptor is logarithmic.
+ * Device drivers must convert that value to linear units themselves.)
+ *
+ * If an isochronous endpoint queue isn't already running, the host
+ * controller will schedule a new URB to start as soon as bandwidth
+ * utilization allows. If the queue is running then a new URB will be
+ * scheduled to start in the first transfer slot following the end of the
+ * preceding URB, if that slot has not already expired. If the slot has
+ * expired (which can happen when IRQ delivery is delayed for a long time),
+ * the scheduling behavior depends on the URB_ISO_ASAP flag. If the flag
+ * is clear then the URB will be scheduled to start in the expired slot,
+ * implying that some of its packets will not be transferred; if the flag
+ * is set then the URB will be scheduled in the first unexpired slot,
+ * breaking the queue's synchronization. Upon URB completion, the
+ * start_frame field will be set to the (micro)frame number in which the
+ * transfer was scheduled. Ranges for frame counter values are HC-specific
+ * and can go from as low as 256 to as high as 65536 frames.
+ *
+ * Isochronous URBs have a different data transfer model, in part because
+ * the quality of service is only "best effort". Callers provide specially
+ * allocated URBs, with number_of_packets worth of iso_frame_desc structures
+ * at the end. Each such packet is an individual ISO transfer. Isochronous
+ * URBs are normally queued, submitted by drivers to arrange that
+ * transfers are at least double buffered, and then explicitly resubmitted
+ * in completion handlers, so
+ * that data (such as audio or video) streams at as constant a rate as the
+ * host controller scheduler can support.
+ *
+ * Completion Callbacks:
+ *
+ * The completion callback is made in_interrupt(), and one of the first
+ * things that a completion handler should do is check the status field.
+ * The status field is provided for all URBs. It is used to report
+ * unlinked URBs, and status for all non-ISO transfers. It should not
+ * be examined before the URB is returned to the completion handler.
+ *
+ * The context field is normally used to link URBs back to the relevant

+ * in interface or class descriptors; endpoints; I/O buffers; and so on.
+ * @unbind: Reverses @bind; called as a side effect of unregistering the
+ * driver which added this function.
+ * @free_func: free the struct usb_function.
+ * @mod: (internal) points to the module that created this structure.
+ * @set_alt: (REQUIRED) Reconfigures altsettings; function drivers may
+ * initialize usb_ep.driver data at this time (when it is used).
+ * Note that setting an interface to its current altsetting resets
+ * interface state, and that all interfaces have a disabled state.
+ * @get_alt: Returns the active altsetting. If this is not provided,
+ * then only altsetting zero is supported.
+ * @disable: (REQUIRED) Indicates the function should be disabled. Reasons
+ * include host resetting or reconfiguring the gadget, and disconnection.
+ * @setup: Used for interface-specific control requests.
+ * @req_match: Tests if a given class request can be handled by this function.
+ * @suspend: Notifies functions when the host stops sending USB traffic.
+ * @resume: Notifies functions when the host restarts USB traffic.
+ * @get_status: Returns function status as a reply to
+ * GetStatus() request when the recipient is Interface.
+ * @func_suspend: callback to be called when
+ * SetFeature(FUNCTION_SUSPEND) is reseived
+ *
+ * A single USB function uses one or more interfaces, and should in most
+ * cases support operation at both full and high speeds. Each function is
+ * associated by @usb_add_function() with a one configuration; that function
+ * causes @bind() to be called so resources can be allocated as part of
+ * setting up a gadget driver. Those resources include endpoints, which
+ * should be allocated using @usb_ep_autoconfig().
+ *
+ * To support dual speed operation, a function driver provides descriptors
+ * for both high and full speed operation. Except in rare cases that don't
+ * involve bulk endpoints, each speed needs different endpoint descriptors.
+ *
+ * Function drivers choose their own strategies for managing instance data.
+ * The simplest strategy just declares it "static', which means the function
+ * can only be activated once. If the function needs to be exposed in more
+ * than one configuration at a given speed, it needs to support multiple
+ * usb_function structures (one for each configuration).
+ *
+ * A more complex strategy might encapsulate a @usb_function structure inside
+ * a driver-specific instance structure to allows multiple activations. An
+ * example of multiple activations might be a CDC ACM function that supports
+ * two or more distinct instances within the same configuration, providing
+ * several independent logical data links to a USB host.

+ * and language IDs provided in control requests. Note: The first entries
+ * are predefined. The first entry that may be used is
+ * USB_GADGET_FIRST_AVAIL_IDX
+ * @max_speed: Highest speed the driver supports.
+ * @needs_serial: set to 1 if the gadget needs userspace to provide
+ * a serial number. If one is not provided, warning will be printed.
+ * @bind: (REQUIRED) Used to allocate resources that are shared across the
+ * whole device, such as string IDs, and add its configurations using
+ * @usb_add_config(). This may fail by returning a negative errno
+ * value; it should return zero on successful initialization.
+ * @unbind: Reverses @bind; called as a side effect of unregistering
+ * this driver.
+ * @disconnect: optional driver disconnect method
+ * @suspend: Notifies when the host stops sending USB traffic,
+ * after function notifications
+ * @resume: Notifies configuration when the host restarts USB traffic,
+ * before function notifications
+ * @gadget_driver: Gadget driver controlling this driver
+ *
+ * Devices default to reporting self powered operation. Devices which rely
+ * on bus powered operation should report this in their @bind method.
+ *
+ * Before returning from @bind, various fields in the template descriptor
+ * may be overridden. These include the idVendor/idProduct/bcdDevice values
+ * normally to bind the appropriate host side driver, and the three strings
+ * (iManufacturer, iProduct, iSerialNumber) normally used to provide user
+ * meaningful device identifiers. (The strings will not be defined unless
+ * they are defined in @dev and @strings.) The correct ep0 maxpacket size
+ * is also reported, as defined by the underlying controller driver.

+ * @dma: DMA address corresponding to 'buf'. If you don't set this
+ * field, and the usb controller needs one, it is responsible
+ * for mapping and unmapping the buffer.
+ * @sg: a scatterlist for SG-capable controllers.
+ * @num_sgs: number of SG entries
+ * @num_mapped_sgs: number of SG entries mapped to DMA (internal)
+ * @length: Length of that data
+ * @stream_id: The stream id, when USB3.0 bulk streams are being used
+ * @no_interrupt: If true, hints that no completion irq is needed.
+ * Helpful sometimes with deep request queues that are handled
+ * directly by DMA controllers.
+ * @zero: If true, when writing data, makes the last packet be "short"
+ * by adding a zero length packet as needed;
+ * @short_not_ok: When reading data, makes short packets be
+ * treated as errors (queue stops advancing till cleanup).
+ * @complete: Function called when request completes, so this request and
+ * its buffer may be re-used. The function will always be called with
+ * interrupts disabled, and it must not sleep.
+ * Reads terminate with a short packet, or when the buffer fills,
+ * whichever comes first. When writes terminate, some data bytes
+ * will usually still be in flight (often in a hardware fifo).
+ * Errors (for reads or writes) stop the queue from advancing
+ * until the completion function returns, so that any transfers
+ * invalidated by the error may first be dequeued.
+ * @context: For use by the completion callback
+ * @list: For use by the gadget driver.
+ * @status: Reports completion code, zero or a negative errno.
+ * Normally, faults block the transfer queue from advancing until
+ * the completion callback returns.
+ * Code "-ESHUTDOWN" indicates completion caused by device disconnect,
+ * or when the driver disabled the endpoint.
+ * @actual: Reports bytes transferred to/from the buffer. For reads (OUT
+ * transfers) this may be less than the requested length. If the
+ * short_not_ok flag is set, short reads are treated as errors
+ * even when status otherwise indicates successful completion.
+ * Note that for writes (IN transfers) some data bytes may still
+ * reside in a device-side FIFO when the request is reported as
+ * complete.
+ *
+ * These are allocated/freed through the endpoint they're used with. The
+ * hardware's driver can add extra per-request data to the memory it returns,
+ * which often avoids separate memory allocations (potential failures),
+ * later when the request is queued.
+ *
+ * Request flags affect request handling, such as whether a zero length
+ * packet is written (the "zero" flag), whether a short read should be
+ * treated as an error (blocking request queue advance, the "short_not_ok"
+ * flag), or hinting that an interrupt is not required (the "no_interrupt"
+ * flag, for use with deep request queues).
+ *
+ * Bulk endpoints can use any size buffers, and can also be used for interrupt
+ * transfers. interrupt-only endpoints can be much less functional.
+ *
+ * NOTE: this is analogous to 'struct urb' on the host side, except that

+ * queues a response to ep0, or returns negative to stall.
+ * @disconnect: Invoked after all transfers have been stopped,
+ * when the host is disconnected. May be called in_interrupt; this
+ * may not sleep. Some devices can't detect disconnect, so this might
+ * not be called except as part of controller shutdown.
+ * @bind: the driver's bind callback
+ * @unbind: Invoked when the driver is unbound from a gadget,
+ * usually from rmmod (after a disconnect is reported).
+ * Called in a context that permits sleeping.
+ * @suspend: Invoked on USB suspend. May be called in_interrupt.
+ * @resume: Invoked on USB resume. May be called in_interrupt.
+ * @reset: Invoked on USB bus reset. It is mandatory for all gadget drivers
+ * and should be called in_interrupt.
+ * @driver: Driver model state for this driver.
+ *
+ * Devices are disabled till a gadget driver successfully bind()s, which
+ * means the driver will handle setup() requests needed to enumerate (and
+ * meet "chapter 9" requirements) then do some useful work.
+ *
+ * If gadget->is_otg is true, the gadget driver must provide an OTG
+ * descriptor during enumeration, or else fail the bind() call. In such
+ * cases, no USB traffic may flow until both bind() returns without
+ * having called usb_gadget_disconnect(), and the USB host stack has
+ * initialized.
+ *
+ * Drivers use hardware-specific knowledge to configure the usb hardware.
+ * endpoint addressing is only one of several hardware characteristics that
+ * are in descriptors the ep0 implementation returns from setup() calls.
+ *
+ * Except for ep0 implementation, most driver code shouldn't need change to
+ * run on top of different usb controllers. It'll use endpoints set up by
+ * that ep0 implementation.
+ *
+ * The usb controller driver handles a few standard usb requests. Those
+ * include set_address, and feature flags for devices, interfaces, and
+ * endpoints (the get_status, set_feature, and clear_feature requests).
+ *
+ * Accordingly, the driver's setup() callback must always implement all
+ * get_descriptor requests, returning at least a device descriptor and
+ * a configuration descriptor. Drivers must make sure the endpoint
+ * descriptors match any hardware constraints. Some hardware also constrains
+ * other descriptors. (The pxa250 allows only configurations 1, 2, or 3).
+ *
+ * The driver's setup() callback must also implement set_configuration,
+ * and should also implement set_interface, get_configuration, and
+ * get_interface. Setting a configuration (or interface) is where
+ * endpoints should be activated or (config 0) shut down.
+ *
+ * (Note that only the default control endpoint is supported. Neither
+ * hosts nor devices generally support control traffic except to ep0.)
+ *
+ * Most devices will ignore USB suspend/resume operations, and so will
+ * not provide those callbacks. However, some may need to change modes
+ * when the host is not longer directing those activities. For example,
+ * local controls (buttons, dials, etc) may need to be re-enabled since
+ * the (remote) host can't do that any longer; or an error state might
+ * be cleared, to make the device behave identically whether or not
+ * power is maintained.

+ *
+ * UMC (UWB Multi-interface Controller) capabilities (e.g., radio
+ * controller, host controller) are presented as devices on the "umc"
+ * bus.
+ *
+ * The radio controller is not strictly a UMC capability but it's
+ * useful to present it as such.
+ *
+ * References:
+ *
+ * [WHCI] Wireless Host Controller Interface Specification for
+ * Certified Wireless Universal Serial Bus, revision 0.95.
+ *
+ * How this works is kind of convoluted but simple. The whci.ko driver
+ * loads when WHCI devices are detected. These WHCI devices expose
+ * many devices in the same PCI function (they couldn't have reused
+ * functions, no), so for each PCI function that exposes these many
+ * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
+ * with umc_device_create() and adds it to the bus with
+ * umc_device_register().
+ *
+ * umc_device_register() calls device_register() which will push the
+ * bus management code to load your UMC driver's somehting_probe()
+ * that you have registered for that capability code.
+ *
+ * Now when the WHCI device is removed, whci_remove() will go over
+ * each umc_dev assigned to each of the PCI function's capabilities
+ * and through whci_del_cap() call umc_device_unregister() each
+ * created umc_dev. Of course, if you are bound to the device, your
+ * driver's something_remove() will be called.

+ * struct vmci_queue_header - VMCI Queue Header information.
+ *
+ * A Queue cannot stand by itself as designed. Each Queue's header
+ * contains a pointer into itself (the producer_tail) and into its peer
+ * (consumer_head). The reason for the separation is one of
+ * accessibility: Each end-point can modify two things: where the next
+ * location to enqueue is within its produce_q (producer_tail); and
+ * where the next dequeue location is in its consume_q (consumer_head).
+ *
+ * An end-point cannot modify the pointers of its peer (guest to
+ * guest; NOTE that in the host both queue headers are mapped r/w).
+ * But, each end-point needs read access to both Queue header
+ * structures in order to determine how much space is used (or left)
+ * in the Queue. This is because for an end-point to know how full
+ * its produce_q is, it needs to use the consumer_head that points into
+ * the produce_q but -that- consumer_head is in the Queue header for
+ * that end-points consume_q.
+ *
+ * Thoroughly confused? Sorry.
+ *
+ * producer_tail: the point to enqueue new entrants. When you approach
+ * a line in a store, for example, you walk up to the tail.
+ *
+ * consumer_head: the point in the queue from which the next element is
+ * dequeued. In other words, who is next in line is he who is at the
+ * head of the line.
+ *
+ * Also, producer_tail points to an empty byte in the Queue, whereas
+ * consumer_head points to a valid byte of data (unless producer_tail ==
+ * consumer_head in which case consumer_head does not point to a valid
+ * byte of data).
+ *
+ * For a queue of buffer 'size' bytes, the tail and head pointers will be in
+ * the range [0, size-1].

+ *
+ *
+ * EXECUTING DEBUGGING ACTIONS OR NOT
+ *
+ * The main thing this framework provides is decission power to take a
+ * debug action (like printing a message) if the current debug level
+ * allows it.
+ *
+ * The decission power is at two levels: at compile-time (what does
+ * not make it is compiled out) and at run-time. The run-time
+ * selection is done per-submodule (as they are declared by the user
+ * of the framework).
+ *
+ * A call to d_test(L) (L being the target debug level) returns true
+ * if the action should be taken because the current debug levels
+ * allow it (both compile and run time).
+ *
+ * It follows that a call to d_test() that can be determined to be
+ * always false at compile time will get the code depending on it
+ * compiled out by optimization.
+ *
+ *
+ * DEBUG LEVELS
+ *
+ * It is up to the caller to define how much a debugging level is.
+ *
+ * Convention sets 0 as "no debug" (so an action marked as debug level 0
+ * will always be taken). The increasing debug levels are used for
+ * increased verbosity.
+ *
+ *
+ * USAGE
+ *
+ * Group the code in modules and submodules inside each module [which
+ * in most cases maps to Linux modules and .c files that compose
+ * those].
+ *
+ *
+ * For each module, there is:
+ *
+ * - a MODULENAME (single word, legal C identifier)
+ *
+ * - a debug-levels.h header file that declares the list of
+ * submodules and that is included by all .c files that use
+ * the debugging tools. The file name can be anything.
+ *
+ * - some (optional) .c code to manipulate the runtime debug levels
+ * through debugfs.
+ *
+ * The debug-levels.h file would look like:
+ *
+ * #ifndef __debug_levels__h__
+ * #define __debug_levels__h__
+ *
+ * #define D_MODULENAME modulename
+ * #define D_MASTER 10
+ *
+ * #include <linux/wimax/debug.h>
+ *
+ * enum d_module {
+ * D_SUBMODULE_DECLARE(submodule_1),
+ * D_SUBMODULE_DECLARE(submodule_2),
+ * ...
+ * D_SUBMODULE_DECLARE(submodule_N)
+ * };
+ *
+ * #endif
+ *
+ * D_MASTER is the maximum compile-time debug level; any debug actions
+ * above this will be out. D_MODULENAME is the module name (legal C
+ * identifier), which has to be unique for each module (to avoid
+ * namespace collisions during linkage). Note those #defines need to
+ * be done before #including debug.h
+ *
+ * We declare N different submodules whose debug level can be
+ * independently controlled during runtime.
+ *
+ * In a .c file of the module (and only in one of them), define the
+ * following code:
+ *
+ * struct d_level D_LEVEL[] = {
+ * D_SUBMODULE_DEFINE(submodule_1),
+ * D_SUBMODULE_DEFINE(submodule_2),
+ * ...
+ * D_SUBMODULE_DEFINE(submodule_N),
+ * };
+ * size_t D_LEVEL_SIZE = ARRAY_SIZE(D_LEVEL);
+ *
+ * Externs for d_level_MODULENAME and d_level_size_MODULENAME are used
+ * and declared in this file using the D_LEVEL and D_LEVEL_SIZE macros
+ * #defined also in this file.
+ *
+ * To manipulate from user space the levels, create a debugfs dentry
+ * and then register each submodule with:
+ *
+ * result = d_level_register_debugfs("PREFIX_", submodule_X, parent);
+ * if (result < 0)
+ * goto error;
+ *
+ * Where PREFIX_ is a name of your chosing. This will create debugfs
+ * file with a single numeric value that can be use to tweak it. To
+ * remove the entires, just use debugfs_remove_recursive() on 'parent'.
+ *
+ * NOTE: remember that even if this will show attached to some
+ * particular instance of a device, the settings are *global*.
+ *
+ *
+ * On each submodule (for example, .c files), the debug infrastructure
+ * should be included like this:
+ *
+ * #define D_SUBMODULE submodule_x // matches one in debug-levels.h
+ * #include "debug-levels.h"
+ *
+ * after #including all your include files.
+ *
+ *
+ * Now you can use the d_*() macros below [d_test(), d_fnstart(),
+ * d_fnend(), d_printf(), d_dump()].
+ *
+ * If their debug level is greater than D_MASTER, they will be
+ * compiled out.
+ *
+ * If their debug level is lower or equal than D_MASTER but greater
+ * than the current debug level of their submodule, they'll be
+ * ignored.
+ *
+ * Otherwise, the action will be performed.

+
+ Compression can be done in a single step if the buffers are large
+ enough (for example if an input file is mmap'ed), or can be done by
+ repeated calls of the compression function. In the latter case, the
+ application must provide more input and/or consume the output
+ (providing more output space) before each call.
+
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio.
+
+ The zlib format was designed to be compact and fast for use in memory
+ and on communications channels. The gzip format was designed for single-
+ file compression on file systems, has a larger header than zlib to maintain
+ directory information, and uses a different, slower check method than zlib.
+
+ The library does not install any signal handler. The decoder checks
+ the consistency of the compressed data, so the library should never
+ crash even in case of corrupted input.

+ deflate compresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce some
+ output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. deflate performs one or both of the
+ following actions:
+
+ - Compress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in and avail_in are updated and
+ processing will resume at this point for the next call of deflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. This action is forced if the parameter flush is non zero.
+ Forcing flush frequently degrades the compression ratio, so this parameter
+ should be set only when necessary (in interactive applications).
+ Some output may be provided even if flush is not set.
+
+ Before the call of deflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming
+ more output, and updating avail_in or avail_out accordingly; avail_out
+ should never be zero before the call. The application can consume the
+ compressed output when it wants, for example when the output buffer is full
+ (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+ and with zero avail_out, it must be called again after making room in the
+ output buffer because there might be more output pending.
+
+ If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+ flushed to the output buffer and the output is aligned on a byte boundary, so
+ that the decompressor can get all input data available so far. (In particular

+ before the call.) Flushing may degrade compression for some compression
+ algorithms and so it should be used only when necessary.
+
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+ the compression.
+
+ If deflate returns with avail_out == 0, this function must be called again

+ avail_out), until the flush is complete (deflate returns with non-zero
+ avail_out).
+
+ If the parameter flush is set to Z_FINISH, pending input is processed,

+ more input data, until it returns with Z_STREAM_END or an error. After
+ deflate has returned Z_STREAM_END, the only possible operations on the
+ stream are deflateReset or deflateEnd.
+
+ Z_FINISH can be used immediately after deflateInit if all the compression
+ is to be done in a single step. In this case, avail_out must be at least

+/*
+ inflate decompresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. inflate performs one or both of the
+ following actions:
+
+ - Decompress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in is updated and processing
+ will resume at this point for the next call of inflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ accordingly. inflate() provides as much output as possible, until there
+ is no more input data or no more space in the output buffer (see below
+ about the flush parameter).
+
+ Before the call of inflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming
+ more output, and updating the next_* and avail_* values accordingly.
+ The application can consume the uncompressed output when it wants, for
+ example when the output buffer is full (avail_out == 0), or after each
+ call of inflate(). If inflate returns Z_OK and with zero avail_out, it
+ must be called again after making room in the output buffer because there
+ might be more output pending.
+
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
+ Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+ if and when it gets to the next deflate block boundary. When decoding the
+ zlib or gzip format, this will cause inflate() to return immediately after
+ the header and before the first block. When doing a raw inflate, inflate()
+ will go ahead and process the first block, and will return when it gets to
+ the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64
+ if inflate() is currently decoding the last block in the deflate stream,
+ plus 128 if inflate() returned immediately after decoding an end-of-block
+ code or decoding the complete header up to just before the first byte of the
+ deflate stream. The end-of-block will not be indicated until all of the
+ uncompressed data from that block has been written to strm->next_out. The
+ number of unused bits may in general be greater than seven, except when
+ bit 7 of data_type is set, in which case the number of unused bits will be
+ less than eight.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step
+ (a single call of inflate), the parameter flush should be set to
+ Z_FINISH. In this case all pending input is processed and all pending
+ output is flushed; avail_out must be large enough to hold all the
+ uncompressed data. (The size of the uncompressed data may have been saved
+ by the compressor for this purpose.) The next operation on this stream must
+ be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+ is never required, but can be used to inform inflate that a faster approach
+ may be used for the single inflate() call.
+
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the only effect of the flush parameter in this implementation
+ is on the return value of inflate(), as noted below, or when it returns early
+ because Z_BLOCK is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the adler32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the adler32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed adler32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() will decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically. Any information
+ contained in the gzip header is not retained, so applications that need that
+ information should instead use raw inflate, see inflateInit2() below, or
+ inflateBack() and perform their own processing of the gzip header and
+ trailer.
+
+ inflate() returns Z_OK if some progress has been made (more input processed
+ or more output produced), Z_STREAM_END if the end of the compressed data has
+ been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+ preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+ corrupted (input stream not conforming to the zlib format or incorrect check
+ value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+ if next_in or next_out was NULL), Z_MEM_ERROR if there was not enough memory,
+ Z_BUF_ERROR if no progress is possible or if there was not enough room in the
+ output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
+ inflate() can be called again with more input and more output space to
+ continue decompressing. If Z_DATA_ERROR is returned, the application may then
+ call inflateSync() to look for a good compression block if a partial recovery
+ of the data is desired.

+
+ The memLevel parameter specifies how much memory should be allocated

+ usage as a function of windowBits and memLevel.
+

+ string match). Filtered data consists mostly of small values with a

+ tuned to compress them better. The effect of Z_FILTERED is to force more

+ v4l2_subdev's init operation in order to load the driver's firmware.
+ Without this the audio standard detection will fail and you will
+ only get mono.
+
+ Since loading the firmware is often problematic when the driver is
+ compiled into the kernel I recommend postponing calling this function
+ until the first open of the video device. Another reason for
+ postponing it is that loading this firmware takes a long time (seconds)
+ due to the slow i2c bus speed. So it will speed up the boot process if
+ you can avoid loading the fw as long as the video device isn't used. */

+/* msp3400 routing
+ ===============
+
+ The msp3400 has a complicated routing scheme with many possible
+ combinations. The details are all in the datasheets but I will try
+ to give a short description here.
+
+ Inputs
+ ======
+
+ There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+ to select which tuner input to use and which SCART input to use. The
+ selected tuner input, the selected SCART input and all I2S inputs go to
+ the DSP (the tuner input first goes through the demodulator).
+
+ The DSP handles things like volume, bass/treble, balance, and some chips
+ have support for surround sound. It has several outputs: MAIN, AUX, I2S
+ and SCART1/2. Each output can select which DSP input to use. So the MAIN
+ output can select the tuner input while at the same time the SCART1 output
+ uses the I2S input.
+
+ Outputs
+ =======
+
+ Most DSP outputs are also the outputs of the msp3400. However, the SCART
+ outputs of the msp3400 can select which input to use: either the SCART1 or
+ SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+ bypassing the DSP.
+
+ Summary
+ =======
+
+ So to specify a complete routing scheme for the msp3400 you will have to
+ specify in the 'input' arg of the s_routing function:
+
+ 1) which tuner input to use
+ 2) which SCART input to use

+ * Drivers should never touch this flag.
+ * @call_notify: If set, then call the handler's notify function whenever the
+ * control's value changes.
+ * @manual_mode_value: If the is_auto flag is set, then this is the value

+ * @elem_size: The size in bytes of the control.
+ * @dims: The size of each dimension.
+ * @nr_of_dims:The number of dimensions in @dims.
+ * @menu_skip_mask: The control's skip mask for menu controls. This makes it
+ * easy to skip menu items that are not valid. If bit X is set,
+ * then menu item X is skipped. Of course, this only works for
+ * menus with <= 32 menu items. There are no menus that come

+ * is in addition to the menu_skip_mask above). The last entry
+ * must be NULL.
+ * @flags: The control's flags.
+ * @cur: The control's current value.
+ * @val: The control's new s32 value.
+ * @val64: The control's new s64 value.
+ * @priv: The control's private pointer. For use by the driver. It is

+/*
+ * Overview:
+ *
+ * Events are subscribed per-filehandle. An event specification consists of a
+ * type and is optionally associated with an object identified through the
+ * 'id' field. So an event is uniquely identified by the (type, id) tuple.
+ *
+ * The v4l2-fh struct has a list of subscribed events. The v4l2_subscribed_event
+ * struct is added to that list, one for every subscribed event.
+ *
+ * Each v4l2_subscribed_event struct ends with an array of v4l2_kevent structs.
+ * This array (ringbuffer, really) is used to store any events raised by the
+ * driver. The v4l2_kevent struct links into the 'available' list of the
+ * v4l2_fh struct so VIDIOC_DQEVENT will know which event to dequeue first.
+ *
+ * Finally, if the event subscription is associated with a particular object
+ * such as a V4L2 control, then that object needs to know about that as well
+ * so that an event can be raised by that object. So the 'node' field can
+ * be used to link the v4l2_subscribed_event struct into a list of that
+ * object.
+ *
+ * So to summarize:
+ *
+ * struct v4l2_fh has two lists: one of the subscribed events, and one of the
+ * pending events.
+ *
+ * struct v4l2_subscribed_event has a ringbuffer of raised (pending) events of
+ * that particular type.
+ *
+ * If struct v4l2_subscribed_event is associated with a specific object, then
+ * that object will have an internal list of struct v4l2_subscribed_event so
+ * it knows who subscribed an event to that object.

+ More categories can be added if needed, although this should remain a
+ limited set (no more than approx. 8 categories).
+

+
+ A subdev driver can leave the pointer to the category ops NULL if
+ it does not implement them (e.g. an audio subdev will generally not
+ implement the video category ops). The exception is the core category:
+ this must always be present.
+
+ These ops are all used internally so it is no problem to change, remove
+ or add ops or move ops from one to another category. Currently these
+ ops are based on the original ioctls, but since ops are not limited to
+ one argument there is room for improvement here once all i2c subdev
+ drivers are converted to use these ops.

+ * the required number of buffers in *num_buffers, the

+ * and optional per-plane allocator specific context in the

+ * of buffers, that are being allocated. When called from
+ * VIDIOC_CREATE_BUFS, fmt != NULL and it describes the
+ * target frame format (if the format isn't valid the
+ * callback must return -EINVAL). In this case *num_buffers
+ * are being allocated additionally to q->num_buffers.
+ * @wait_prepare: release any locks taken while calling vb2 functions;
+ * it is called before an ioctl needs to wait for a new
+ * buffer to arrive; required to avoid a deadlock in
+ * blocking access type.
+ * @wait_finish: reacquire all locks released in the previous callback;
+ * required to continue operation after sleeping while
+ * waiting for a new buffer to arrive.
+ * @buf_init: called once after allocating a buffer (in MMAP case)
+ * or after acquiring a new USERPTR buffer; drivers may
+ * perform additional buffer-related initialization;
+ * initialization failure (return != 0) will prevent
+ * queue setup from completing successfully; optional.
+ * @buf_prepare: called every time the buffer is queued from userspace
+ * and from the VIDIOC_PREPARE_BUF ioctl; drivers may
+ * perform any initialization required before each
+ * hardware operation in this callback; drivers can
+ * access/modify the buffer here as it is still synced for
+ * the CPU; drivers that support VIDIOC_CREATE_BUFS must
+ * also validate the buffer size; if an error is returned,
+ * the buffer will not be queued in driver; optional.
+ * @buf_finish: called before every dequeue of the buffer back to
+ * userspace; the buffer is synced for the CPU, so drivers
+ * can access/modify the buffer contents; drivers may
+ * perform any operations required before userspace
+ * accesses the buffer; optional. The buffer state can be
+ * one of the following: DONE and ERROR occur while
+ * streaming is in progress, and the PREPARED state occurs
+ * when the queue has been canceled and all pending
+ * buffers are being returned to their default DEQUEUED
+ * state. Typically you only have to do something if the
+ * state is VB2_BUF_STATE_DONE, since in all other cases
+ * the buffer contents will be ignored anyway.
+ * @buf_cleanup: called once before the buffer is freed; drivers may
+ * perform any additional cleanup; optional.
+ * @start_streaming: called once to enter 'streaming' state; the driver may
+ * receive buffers with @buf_queue callback before
+ * @start_streaming is called; the driver gets the number
+ * of already queued buffers in count parameter; driver
+ * can return an error if hardware fails, in that case all
+ * buffers that have been already given by the @buf_queue
+ * callback are to be returned by the driver by calling
+ * @vb2_buffer_done(VB2_BUF_STATE_QUEUED).
+ * If you need a minimum number of buffers before you can
+ * start streaming, then set @min_buffers_needed in the
+ * vb2_queue structure. If that is non-zero then
+ * start_streaming won't be called until at least that
+ * many buffers have been queued up by userspace.
+ * @stop_streaming: called when 'streaming' state must be disabled; driver
+ * should stop any DMA transactions or wait until they
+ * finish and give back all buffers it got from buf_queue()
+ * callback by calling @vb2_buffer_done() with either
+ * VB2_BUF_STATE_DONE or VB2_BUF_STATE_ERROR; may use
+ * vb2_wait_for_all_buffers() function
+ * @buf_queue: passes buffer vb to the driver; driver may start
+ * hardware operation on this buffer; driver should give
+ * the buffer back by calling vb2_buffer_done() function;
+ * it is allways called after calling STREAMON ioctl;
+ * might be called before start_streaming callback if user
+ * pre-queued buffers before calling STREAMON.

+ * long as you hold a device, you must also guarantee that you have a valid
+ * reference to the device via hci_conn_get() (or the initial reference from
+ * hci_conn_add()).
+ * The hold()/drop() ref-count is known to drop below 0 sometimes, which doesn't

+ * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
+ * userspace and drivers, and offers some utility functionality associated
+ * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
+ * by all modern wireless drivers in Linux, so that they offer a consistent
+ * API through nl80211. For backward compatibility, cfg80211 also offers
+ * wireless extensions to userspace, but hides them from drivers completely.
+ *
+ * Additionally, cfg80211 contains code to help enforce regulatory spectrum
+ * use restrictions.

+/**
+ * DOC: Device registration
+ *
+ * In order for a driver to use cfg80211, it must register the hardware device
+ * with cfg80211. This happens through a number of hardware capability structs
+ * described below.
+ *
+ * The fundamental structure for each device is the 'wiphy', of which each
+ * instance describes a physical wireless device connected to the system. Each
+ * such wiphy can have zero, one, or many virtual interfaces associated with
+ * it, which need to be identified as such by pointing the network interface's
+ * @ieee80211_ptr pointer to a &struct wireless_dev which further describes
+ * the wireless part of the interface, normally this struct is embedded in the
+ * network interface's private data area. Drivers can optionally allow creating
+ * or destroying virtual interfaces on the fly, but without at least one or the
+ * ability to create some the wireless device isn't useful.
+ *
+ * Each wiphy structure contains device capability information, and also has
+ * a pointer to the various operations the driver offers. The definitions and
+ * structures here describe these capabilities in detail.

+/**
+ * struct cfg80211_ops - backend description for wireless configuration
+ *
+ * This struct is registered by fullmac card drivers and/or wireless stacks
+ * in order to handle configuration requests on their interfaces.
+ *
+ * All callbacks except where otherwise noted should return 0
+ * on success or a negative error code.
+ *
+ * All operations are currently invoked under rtnl for consistency with the
+ * wireless extensions but this is subject to reevaluation as soon as this
+ * code is used more widely and we have a first user without wext.
+ *
+ * @suspend: wiphy device needs to be suspended. The variable @wow will
+ * be %NULL or contain the enabled Wake-on-Wireless triggers that are
+ * configured for the device.
+ * @resume: wiphy device needs to be resumed
+ * @set_wakeup: Called when WoWLAN is enabled/disabled, use this callback
+ * to call device_set_wakeup_enable() to enable/disable wakeup from
+ * the device.
+ *
+ * @add_virtual_intf: create a new virtual interface with the given name,
+ * must set the struct wireless_dev's iftype. Beware: You must create
+ * the new netdev in the wiphy's network namespace! Returns the struct
+ * wireless_dev, or an ERR_PTR. For P2P device wdevs, the driver must
+ * also set the address member in the wdev.
+ *
+ * @del_virtual_intf: remove the virtual interface
+ *
+ * @change_virtual_intf: change type/configuration of virtual interface,
+ * keep the struct wireless_dev's iftype updated.
+ *
+ * @add_key: add a key with the given parameters. @mac_addr will be %NULL
+ * when adding a group key.
+ *
+ * @get_key: get information about the key with the given parameters.
+ * @mac_addr will be %NULL when requesting information for a group
+ * key. All pointers given to the @callback function need not be valid
+ * after it returns. This function should return an error if it is
+ * not possible to retrieve the key, -ENOENT if it doesn't exist.
+ *
+ * @del_key: remove a key given the @mac_addr (%NULL for a group key)
+ * and @key_index, return -ENOENT if the key doesn't exist.
+ *
+ * @set_default_key: set the default key on an interface
+ *
+ * @set_default_mgmt_key: set the default management frame key on an interface
+ *
+ * @set_rekey_data: give the data necessary for GTK rekeying to the driver
+ *
+ * @start_ap: Start acting in AP mode defined by the parameters.
+ * @change_beacon: Change the beacon parameters for an access point mode
+ * interface. This should reject the call when AP mode wasn't started.
+ * @stop_ap: Stop being an AP, including stopping beaconing.
+ *
+ * @add_station: Add a new station.
+ * @del_station: Remove a station
+ * @change_station: Modify a given station. Note that flags changes are not much
+ * validated in cfg80211, in particular the auth/assoc/authorized flags
+ * might come to the driver in invalid combinations -- make sure to check
+ * them, also against the existing state! Drivers must call
+ * cfg80211_check_station_change() to validate the information.
+ * @get_station: get station information for the station identified by @mac
+ * @dump_station: dump station callback -- resume dump at index @idx
+ *
+ * @add_mpath: add a fixed mesh path
+ * @del_mpath: delete a given mesh path
+ * @change_mpath: change a given mesh path
+ * @get_mpath: get a mesh path for the given parameters
+ * @dump_mpath: dump mesh path callback -- resume dump at index @idx
+ * @get_mpp: get a mesh proxy path for the given parameters
+ * @dump_mpp: dump mesh proxy path callback -- resume dump at index @idx
+ * @join_mesh: join the mesh network with the specified parameters
+ * (invoked with the wireless_dev mutex held)
+ * @leave_mesh: leave the current mesh network
+ * (invoked with the wireless_dev mutex held)
+ *
+ * @get_mesh_config: Get the current mesh configuration
+ *
+ * @update_mesh_config: Update mesh parameters on a running mesh.
+ * The mask is a bitfield which tells us which parameters to
+ * set, and which to leave alone.
+ *
+ * @change_bss: Modify parameters for a given BSS.
+ *
+ * @set_txq_params: Set TX queue parameters
+ *
+ * @libertas_set_mesh_channel: Only for backward compatibility for libertas,
+ * as it doesn't implement join_mesh and needs to set the channel to
+ * join the mesh instead.
+ *
+ * @set_monitor_channel: Set the monitor mode channel for the device. If other
+ * interfaces are active this callback should reject the configuration.
+ * If no interfaces are active or the device is down, the channel should
+ * be stored for when a monitor interface becomes active.
+ *
+ * @scan: Request to do a scan. If returning zero, the scan request is given
+ * the driver, and will be valid until passed to cfg80211_scan_done().
+ * For scan results, call cfg80211_inform_bss(); you can call this outside
+ * the scan/scan_done bracket too.
+ *
+ * @auth: Request to authenticate with the specified peer
+ * (invoked with the wireless_dev mutex held)
+ * @assoc: Request to (re)associate with the specified peer
+ * (invoked with the wireless_dev mutex held)
+ * @deauth: Request to deauthenticate from the specified peer
+ * (invoked with the wireless_dev mutex held)
+ * @disassoc: Request to disassociate from the specified peer
+ * (invoked with the wireless_dev mutex held)
+ *
+ * @connect: Connect to the ESS with the specified parameters. When connected,
+ * call cfg80211_connect_result() with status code %WLAN_STATUS_SUCCESS.
+ * If the connection fails for some reason, call cfg80211_connect_result()
+ * with the status from the AP.
+ * (invoked with the wireless_dev mutex held)
+ * @disconnect: Disconnect from the BSS/ESS.
+ * (invoked with the wireless_dev mutex held)
+ *
+ * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call
+ * cfg80211_ibss_joined(), also call that function when changing BSSID due
+ * to a merge.
+ * (invoked with the wireless_dev mutex held)
+ * @leave_ibss: Leave the IBSS.
+ * (invoked with the wireless_dev mutex held)
+ *
+ * @set_mcast_rate: Set the specified multicast rate (only if vif is in ADHOC or
+ * MESH mode)
+ *
+ * @set_wiphy_params: Notify that wiphy parameters have changed;
+ * @changed bitfield (see &enum wiphy_params_flags) describes which values
+ * have changed. The actual parameter values are available in
+ * struct wiphy. If returning an error, no value should be changed.
+ *
+ * @set_tx_power: set the transmit power according to the parameters,
+ * the power passed is in mBm, to get dBm use MBM_TO_DBM(). The
+ * wdev may be %NULL if power was set for the wiphy, and will
+ * always be %NULL unless the driver supports per-vif TX power
+ * (as advertised by the nl80211 feature flag.)
+ * @get_tx_power: store the current TX power into the dbm variable;
+ * return 0 if successful
+ *
+ * @set_wds_peer: set the WDS peer for a WDS interface
+ *
+ * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting
+ * functions to adjust rfkill hw state
+ *
+ * @dump_survey: get site survey information.
+ *
+ * @remain_on_channel: Request the driver to remain awake on the specified
+ * channel for the specified duration to complete an off-channel
+ * operation (e.g., public action frame exchange). When the driver is
+ * ready on the requested channel, it must indicate this with an event
+ * notification by calling cfg80211_ready_on_channel().
+ * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
+ * This allows the operation to be terminated prior to timeout based on
+ * the duration value.
+ * @mgmt_tx: Transmit a management frame.
+ * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management
+ * frame on another channel
+ *
+ * @testmode_cmd: run a test mode command; @wdev may be %NULL
+ * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be
+ * used by the function, but 0 and 1 must not be touched. Additionally,
+ * return error codes other than -ENOBUFS and -ENOENT will terminate the
+ * dump and return to userspace with an error, so be careful. If any data
+ * was passed in from userspace then the data/len arguments will be present
+ * and point to the data contained in %NL80211_ATTR_TESTDATA.
+ *
+ * @set_bitrate_mask: set the bitrate mask configuration
+ *
+ * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
+ * devices running firmwares capable of generating the (re) association
+ * RSN IE. It allows for faster roaming between WPA2 BSSIDs.
+ * @del_pmksa: Delete a cached PMKID.
+ * @flush_pmksa: Flush all cached PMKIDs.
+ * @set_power_mgmt: Configure WLAN power management. A timeout value of -1
+ * allows the driver to adjust the dynamic ps timeout value.
+ * @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold.
+ * @set_cqm_txe_config: Configure connection quality monitor TX error
+ * thresholds.
+ * @sched_scan_start: Tell the driver to start a scheduled scan.
+ * @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan. This
+ * call must stop the scheduled scan and be ready for starting a new one
+ * before it returns, i.e. @sched_scan_start may be called immediately
+ * after that again and should not fail in that case. The driver should
+ * not call cfg80211_sched_scan_stopped() for a requested stop (when this
+ * method returns 0.)
+ *
+ * @mgmt_frame_register: Notify driver that a management frame type was
+ * registered. Note that this callback may not sleep, and cannot run
+ * concurrently with itself.
+ *
+ * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
+ * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
+ * reject TX/RX mask combinations they cannot support by returning -EINVAL
+ * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
+ *
+ * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
+ *
+ * @tdls_mgmt: Transmit a TDLS management frame.
+ * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup).
+ *
+ * @probe_client: probe an associated client, must return a cookie that it
+ * later passes to cfg80211_probe_status().
+ *
+ * @set_noack_map: Set the NoAck Map for the TIDs.
+ *
+ * @get_channel: Get the current operating channel for the virtual interface.
+ * For monitor interfaces, it should return %NULL unless there's a single
+ * current monitoring channel.
+ *
+ * @start_p2p_device: Start the given P2P device.
+ * @stop_p2p_device: Stop the given P2P device.
+ *
+ * @set_mac_acl: Sets MAC address control list in AP and P2P GO mode.
+ * Parameters include ACL policy, an array of MAC address of stations
+ * and the number of MAC addresses. If there is already a list in driver
+ * this new list replaces the existing one. Driver has to clear its ACL
+ * when number of MAC addresses entries is passed as 0. Drivers which
+ * advertise the support for MAC based ACL have to implement this callback.
+ *
+ * @start_radar_detection: Start radar detection in the driver.
+ *
+ * @update_ft_ies: Provide updated Fast BSS Transition information to the
+ * driver. If the SME is in the driver/firmware, this information can be
+ * used in building Authentication and Reassociation Request frames.
+ *
+ * @crit_proto_start: Indicates a critical protocol needs more link reliability
+ * for a given duration (milliseconds). The protocol is provided so the
+ * driver can take the most appropriate actions.
+ * @crit_proto_stop: Indicates critical protocol no longer needs increased link
+ * reliability. This operation can not fail.
+ * @set_coalesce: Set coalesce parameters.
+ *
+ * @channel_switch: initiate channel-switch procedure (with CSA). Driver is
+ * responsible for veryfing if the switch is possible. Since this is
+ * inherently tricky driver may decide to disconnect an interface later
+ * with cfg80211_stop_iface(). This doesn't mean driver can accept
+ * everything. It should do it's best to verify requests and reject them
+ * as soon as possible.
+ *
+ * @set_qos_map: Set QoS mapping information to the driver
+ *
+ * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the
+ * given interface This is used e.g. for dynamic HT 20/40 MHz channel width
+ * changes during the lifetime of the BSS.
+ *
+ * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device
+ * with the given parameters; action frame exchange has been handled by
+ * userspace so this just has to modify the TX path to take the TS into
+ * account.
+ * If the admitted time is 0 just validate the parameters to make sure
+ * the session can be created at all; it is valid to just always return
+ * success for that but that may result in inefficient behaviour (handshake
+ * with the peer followed by immediate teardown when the addition is later
+ * rejected)
+ * @del_tx_ts: remove an existing TX TS
+ *
+ * @join_ocb: join the OCB network with the specified parameters
+ * (invoked with the wireless_dev mutex held)
+ * @leave_ocb: leave the current OCB network
+ * (invoked with the wireless_dev mutex held)
+ *
+ * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
+ * is responsible for continually initiating channel-switching operations
+ * and returning to the base channel for communication with the AP.
+ * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
+ * peers must be on the base channel when the call completes.

+/************************** DOCUMENTATION **************************/
+/*
+ * Initial driver API (1996 -> onward) :
+ * -----------------------------------
+ * The initial API just sends the IOCTL request received from user space
+ * to the driver (via the driver ioctl handler). The driver has to
+ * handle all the rest...
+ *
+ * The initial API also defines a specific handler in struct net_device
+ * to handle wireless statistics.
+ *
+ * The initial APIs served us well and has proven a reasonably good design.
+ * However, there is a few shortcommings :
+ * o No events, everything is a request to the driver.
+ * o Large ioctl function in driver with gigantic switch statement
+ * (i.e. spaghetti code).
+ * o Driver has to mess up with copy_to/from_user, and in many cases
+ * does it unproperly. Common mistakes are :
+ * * buffer overflows (no checks or off by one checks)
+ * * call copy_to/from_user with irq disabled
+ * o The user space interface is tied to ioctl because of the use
+ * copy_to/from_user.
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * The new driver API is just a bunch of standard functions (handlers),
+ * each handling a specific Wireless Extension. The driver just export
+ * the list of handler it supports, and those will be called apropriately.
+ *
+ * I tried to keep the main advantage of the previous API (simplicity,
+ * efficiency and light weight), and also I provide a good dose of backward
+ * compatibility (most structures are the same, driver can use both API
+ * simultaneously, ...).
+ * Hopefully, I've also addressed the shortcomming of the initial API.
+ *
+ * The advantage of the new API are :
+ * o Handling of Extensions in driver broken in small contained functions
+ * o Tighter checks of ioctl before calling the driver
+ * o Flexible commit strategy (at least, the start of it)
+ * o Backward compatibility (can be mixed with old API)
+ * o Driver doesn't have to worry about memory and user-space issues
+ * The last point is important for the following reasons :
+ * o You are now able to call the new driver API from any API you
+ * want (including from within other parts of the kernel).
+ * o Common mistakes are avoided (buffer overflow, user space copy
+ * with irq disabled and so on).
+ *
+ * The Drawback of the new API are :
+ * o bloat (especially kernel)
+ * o need to migrate existing drivers to new API
+ * My initial testing shows that the new API adds around 3kB to the kernel
+ * and save between 0 and 5kB from a typical driver.
+ * Also, as all structures and data types are unchanged, the migration is
+ * quite straightforward (but tedious).
+ *
+ * ---
+ *
+ * The new driver API is defined below in this file. User space should
+ * not be aware of what's happening down there...
+ *
+ * A new kernel wrapper is in charge of validating the IOCTLs and calling
+ * the appropriate driver handler. This is implemented in :
+ * # net/core/wireless.c
+ *
+ * The driver export the list of handlers in :
+ * # include/linux/netdevice.h (one place)
+ *
+ * The new driver API is available for WIRELESS_EXT >= 13.
+ * Good luck with migration to the new API ;-)
+ */
+
+/* ---------------------- THE IMPLEMENTATION ---------------------- */
+/*
+ * Some of the choice I've made are pretty controversials. Defining an
+ * API is very much weighting compromises. This goes into some of the
+ * details and the thinking behind the implementation.
+ *
+ * Implementation goals :
+ * --------------------
+ * The implementation goals were as follow :
+ * o Obvious : you should not need a PhD to understand what's happening,
+ * the benefit is easier maintenance.
+ * o Flexible : it should accommodate a wide variety of driver
+ * implementations and be as flexible as the old API.
+ * o Lean : it should be efficient memory wise to minimise the impact
+ * on kernel footprint.
+ * o Transparent to user space : the large number of user space
+ * applications that use Wireless Extensions should not need
+ * any modifications.
+ *
+ * Array of functions versus Struct of functions
+ * ---------------------------------------------
+ * 1) Having an array of functions allow the kernel code to access the
+ * handler in a single lookup, which is much more efficient (think hash
+ * table here).
+ * 2) The only drawback is that driver writer may put their handler in
+ * the wrong slot. This is trivial to test (I set the frequency, the
+ * bitrate changes). Once the handler is in the proper slot, it will be
+ * there forever, because the array is only extended at the end.
+ * 3) Backward/forward compatibility : adding new handler just require
+ * extending the array, so you can put newer driver in older kernel
+ * without having to patch the kernel code (and vice versa).
+ *
+ * All handler are of the same generic type
+ * ----------------------------------------
+ * That's a feature !!!
+ * 1) Having a generic handler allow to have generic code, which is more
+ * efficient. If each of the handler was individually typed I would need
+ * to add a big switch in the kernel (== more bloat). This solution is
+ * more scalable, adding new Wireless Extensions doesn't add new code.
+ * 2) You can use the same handler in different slots of the array. For
+ * hardware, it may be more efficient or logical to handle multiple
+ * Wireless Extensions with a single function, and the API allow you to
+ * do that. (An example would be a single record on the card to control
+ * both bitrate and frequency, the handler would read the old record,
+ * modify it according to info->cmd and rewrite it).
+ *
+ * Functions prototype uses union iwreq_data
+ * -----------------------------------------
+ * Some would have preferred functions defined this way :
+ * static int mydriver_ioctl_setrate(struct net_device *dev,
+ * long rate, int auto)
+ * 1) The kernel code doesn't "validate" the content of iwreq_data, and
+ * can't do it (different hardware may have different notion of what a
+ * valid frequency is), so we don't pretend that we do it.
+ * 2) The above form is not extendable. If I want to add a flag (for
+ * example to distinguish setting max rate and basic rate), I would
+ * break the prototype. Using iwreq_data is more flexible.
+ * 3) Also, the above form is not generic (see above).
+ * 4) I don't expect driver developper using the wrong field of the
+ * union (Doh !), so static typechecking doesn't add much value.
+ * 5) Lastly, you can skip the union by doing :
+ * static int mydriver_ioctl_setrate(struct net_device *dev,
+ * struct iw_request_info *info,
+ * struct iw_param *rrq,
+ * char *extra)
+ * And then adding the handler in the array like this :
+ * (iw_handler) mydriver_ioctl_setrate, // SIOCSIWRATE
+ *
+ * Using functions and not a registry
+ * ----------------------------------
+ * Another implementation option would have been for every instance to
+ * define a registry (a struct containing all the Wireless Extensions)
+ * and only have a function to commit the registry to the hardware.
+ * 1) This approach can be emulated by the current code, but not
+ * vice versa.
+ * 2) Some drivers don't keep any configuration in the driver, for them
+ * adding such a registry would be a significant bloat.
+ * 3) The code to translate from Wireless Extension to native format is
+ * needed anyway, so it would not reduce significantely the amount of code.
+ * 4) The current approach only selectively translate Wireless Extensions
+ * to native format and only selectively set, whereas the registry approach
+ * would require to translate all WE and set all parameters for any single
+ * change.
+ * 5) For many Wireless Extensions, the GET operation return the current
+ * dynamic value, not the value that was set.
+ *
+ * This header is <net/iw_handler.h>
+ * ---------------------------------
+ * 1) This header is kernel space only and should not be exported to
+ * user space. Headers in "include/linux/" are exported, headers in
+ * "include/net/" are not.
+ *
+ * Mixed 32/64 bit issues
+ * ----------------------
+ * The Wireless Extensions are designed to be 64 bit clean, by using only
+ * datatypes with explicit storage size.
+ * There are some issues related to kernel and user space using different
+ * memory model, and in particular 64bit kernel with 32bit user space.
+ * The problem is related to struct iw_point, that contains a pointer
+ * that *may* need to be translated.
+ * This is quite messy. The new API doesn't solve this problem (it can't),
+ * but is a step in the right direction :
+ * 1) Meta data about each ioctl is easily available, so we know what type
+ * of translation is needed.
+ * 2) The move of data between kernel and user space is only done in a single
+ * place in the kernel, so adding specific hooks in there is possible.
+ * 3) In the long term, it allows to move away from using ioctl as the
+ * user space API.
+ *
+ * So many comments and so few code
+ * --------------------------------
+ * That's a feature. Comments won't bloat the resulting kernel binary.

+ * The first exception is for hardware encryption and decryption offload

+ * DOC: mac80211 software tx queueing
+ *
+ * mac80211 provides an optional intermediate queueing implementation designed
+ * to allow the driver to keep hardware queues short and provide some fairness
+ * between different stations/interfaces.
+ * In this model, the driver pulls data frames from the mac80211 queue instead
+ * of letting mac80211 push them via drv_tx().
+ * Other frames (e.g. control or management) are still pushed using drv_tx().
+ *
+ * Drivers indicate that they use this model by implementing the .wake_tx_queue
+ * driver operation.
+ *
+ * Intermediate queues (struct ieee80211_txq) are kept per-sta per-tid, with a
+ * single per-vif queue for multicast data frames.
+ *
+ * The driver is expected to initialize its private per-queue data for stations
+ * and interfaces in the .add_interface and .sta_add ops.

+ * @arp_addr_list: List of IPv4 addresses for hardware ARP filtering. The

+ * The driver must allow ARP queries targeted for all address listed here
+ * to pass through. An empty list implies no ARP queries need to pass.
+ * @arp_addr_cnt: Number of addresses currently on the list. Note that this

+ * @IEEE80211_TX_CTL_CLEAR_PS_FILT: clear powersave filter for destination
+ * station
+ * @IEEE80211_TX_CTL_FIRST_FRAGMENT: this is a first fragment of the frame
+ * @IEEE80211_TX_CTL_SEND_AFTER_DTIM: send this frame after DTIM beacon
+ * @IEEE80211_TX_CTL_AMPDU: this frame should be sent as part of an A-MPDU
+ * @IEEE80211_TX_CTL_INJECTED: Frame was injected, internal to mac80211.
+ * @IEEE80211_TX_STAT_TX_FILTERED: The frame was not transmitted
+ * because the destination STA was in powersave mode. Note that to
+ * avoid race conditions, the filter must be set by the hardware or
+ * firmware upon receiving a frame that indicates that the station
+ * went to sleep (must be done on device to filter frames already on

+ * that by setting the IEEE80211_TX_CTL_CLEAR_PS_FILT (see above),
+ * since only then is it guaranteed that no more frames are in the

+ * @IEEE80211_TX_STAT_ACK: Frame was acknowledged

+ * @IEEE80211_TX_INTFL_NEED_TXPROCESSING: completely internal to mac80211,
+ * used to indicate that a pending frame requires TX processing before

+ * used to indicate that a frame was already retried due to PS
+ * @IEEE80211_TX_INTFL_DONT_ENCRYPT: completely internal to mac80211,
+ * used to indicate frame should not be encrypted
+ * @IEEE80211_TX_CTL_NO_PS_BUFFER: This frame is a response to a poll
+ * frame (PS-Poll or uAPSD) or a non-bufferable MMPDU and must
+ * be sent although the station is in powersave mode.
+ * @IEEE80211_TX_CTL_MORE_FRAMES: More frames will be passed to the
+ * transmit function after the current frame, this can be used
+ * by drivers to kick the DMA queue only if unset or when the
+ * queue gets full.
+ * @IEEE80211_TX_INTFL_RETRANSMISSION: This frame is being retransmitted
+ * after TX status because the destination was asleep, it must not
+ * be modified again (no seqno assignment, crypto, etc.)
+ * @IEEE80211_TX_INTFL_MLME_CONN_TX: This frame was transmitted by the MLME
+ * code for connection establishment, this indicates that its status
+ * should kick the MLME state machine.
+ * @IEEE80211_TX_INTFL_NL80211_FRAME_TX: Frame was requested through nl80211
+ * MLME command (internal to mac80211 to figure out whether to send TX
+ * status to user space)
+ * @IEEE80211_TX_CTL_LDPC: tells the driver to use LDPC for this frame
+ * @IEEE80211_TX_CTL_STBC: Enables Space-Time Block Coding (STBC) for this
+ * frame and selects the maximum number of streams that it can use.
+ * @IEEE80211_TX_CTL_TX_OFFCHAN: Marks this packet to be transmitted on
+ * the off-channel channel when a remain-on-channel offload is done
+ * in hardware -- normal packets still flow and are expected to be

+ * @IEEE80211_TX_INTFL_TKIP_MIC_FAILURE: Marks this packet to be used for TKIP
+ * testing. It will be sent out with incorrect Michael MIC key to allow
+ * TKIP countermeasures to be tested.
+ * @IEEE80211_TX_CTL_NO_CCK_RATE: This frame will be sent at non CCK rate.
+ * This flag is actually used for management frame especially for P2P
+ * frames not being sent at CCK rate in 2GHz band.
+ * @IEEE80211_TX_STATUS_EOSP: This packet marks the end of service period,
+ * when its status is reported the service period ends. For frames in
+ * an SP that mac80211 transmits, it is already set; for driver frames
+ * the driver may set this flag. It is also used to do the same for
+ * PS-Poll responses.
+ * @IEEE80211_TX_CTL_USE_MINRATE: This frame will be sent at lowest rate.
+ * This flag is used to send nullfunc frame at minimum rate when
+ * the nullfunc is used for connection monitoring purpose.
+ * @IEEE80211_TX_CTL_DONTFRAG: Don't fragment this packet even if it
+ * would be fragmented by size (this is optional, only used for
+ * monitor injection).
+ * @IEEE80211_TX_STAT_NOACK_TRANSMITTED: A frame that was marked with
+ * IEEE80211_TX_CTL_NO_ACK has been successfully transmitted without
+ * any errors (like issues specific to the driver/HW).

+ * Hardware has support for dynamic PS.

+ * This device needs to get data from beacon before association (i.e.
+ * dtim_period).
+ *
+ * @IEEE80211_HW_SUPPORTS_PER_STA_GTK: The device's crypto engine supports
+ * per-station GTKs as used by IBSS RSN or during fast transition. If

+ *
+ * @IEEE80211_HW_NO_AUTO_VIF: The driver would like for no wlanX to

+ *
+ * @IEEE80211_HW_SW_CRYPTO_CONTROL: The driver wants to control which of the
+ * crypto algorithms can be done in software - so don't automatically
+ * try to fall back to it if hardware crypto fails, but do so only if
+ * the driver returns 1. This also forces the driver to advertise its

+ *
+ * @IEEE80211_HW_QUEUE_CONTROL: The driver wants to control per-interface

+ *
+ * @IEEE80211_HW_SUPPORTS_HT_CCK_RATES: Hardware supports mixing HT/CCK rates

+ * DOC: Hardware crypto acceleration

+ * acceleration designs for encryption and decryption operations.
+ *
+ * The set_key() callback in the &struct ieee80211_ops for a given
+ * device is called to enable hardware acceleration of encryption and
+ * decryption. The callback takes a @sta parameter that will be NULL
+ * for default keys or keys used for transmission only, or point to
+ * the station information for the peer for individual keys.
+ * Multiple transmission keys with the same key index may be used when
+ * VLANs are configured for an access point.
+ *
+ * When transmitting, the TX control data will use the @hw_key_idx
+ * selected by the driver by modifying the &struct ieee80211_key_conf
+ * pointed to by the @key parameter to the set_key() function.
+ *
+ * The set_key() call for the %SET_KEY command should return 0 if
+ * the key is now in use, -%EOPNOTSUPP or -%ENOSPC if it couldn't be
+ * added; if you return 0 then hw_key_idx must be assigned to the
+ * hardware key index, you are free to use the full u8 range.
+ *
+ * Note that in the case that the @IEEE80211_HW_SW_CRYPTO_CONTROL flag is
+ * set, mac80211 will not automatically fall back to software crypto if
+ * enabling hardware crypto failed. The set_key() call may also return the
+ * value 1 to permit this specific key/algorithm to be done in software.
+ *
+ * When the cmd is %DISABLE_KEY then it must succeed.
+ *
+ * Note that it is permissible to not decrypt a frame even if a key
+ * for it has been uploaded to hardware, the stack will not make any
+ * decision based on whether a key has been uploaded or not but rather
+ * based on the receive flags.
+ *
+ * The &struct ieee80211_key_conf structure pointed to by the @key
+ * parameter is guaranteed to be valid until another call to set_key()
+ * removes it, but it can only be used as a cookie to differentiate
+ * keys.
+ *
+ * In TKIP some HW need to be provided a phase 1 key, for RX decryption
+ * acceleration (i.e. iwlwifi). Those drivers should provide update_tkip_key
+ * handler.
+ * The update_tkip_key() call updates the driver with the new phase 1 key.
+ * This happens every time the iv16 wraps around (every 65536 packets). The
+ * set_key() call will happen only once for each key (unless the AP did
+ * rekeying), it will not include a valid phase 1 key. The valid phase 1 key is
+ * provided by update_tkip_key only. The trigger that makes mac80211 call this
+ * handler is software decryption with wrap around of iv16.
+ *
+ * The set_default_unicast_key() call updates the default WEP key index
+ * configured to the hardware for WEP encryption type. This is required
+ * for devices that support offload of data packets (e.g. ARP responses).

+
+/**
+ * DOC: Powersave support
+ *
+ * mac80211 has support for various powersave implementations.
+ *
+ * First, it can support hardware that handles all powersaving by itself,
+ * such hardware should simply set the %IEEE80211_HW_SUPPORTS_PS hardware
+ * flag. In that case, it will be told about the desired powersave mode
+ * with the %IEEE80211_CONF_PS flag depending on the association status.
+ * The hardware must take care of sending nullfunc frames when necessary,
+ * i.e. when entering and leaving powersave mode. The hardware is required
+ * to look at the AID in beacons and signal to the AP that it woke up when
+ * it finds traffic directed to it.
+ *
+ * %IEEE80211_CONF_PS flag enabled means that the powersave mode defined in
+ * IEEE 802.11-2007 section 11.2 is enabled. This is not to be confused
+ * with hardware wakeup and sleep states. Driver is responsible for waking
+ * up the hardware before issuing commands to the hardware and putting it
+ * back to sleep at appropriate times.
+ *
+ * When PS is enabled, hardware needs to wakeup for beacons and receive the
+ * buffered multicast/broadcast frames after the beacon. Also it must be
+ * possible to send frames and receive the acknowledment frame.
+ *
+ * Other hardware designs cannot send nullfunc frames by themselves and also
+ * need software support for parsing the TIM bitmap. This is also supported
+ * by mac80211 by combining the %IEEE80211_HW_SUPPORTS_PS and
+ * %IEEE80211_HW_PS_NULLFUNC_STACK flags. The hardware is of course still
+ * required to pass up beacons. The hardware is still required to handle
+ * waking up for multicast traffic; if it cannot the driver must handle that
+ * as best as it can, mac80211 is too slow to do that.
+ *
+ * Dynamic powersave is an extension to normal powersave in which the
+ * hardware stays awake for a user-specified period of time after sending a
+ * frame so that reply frames need not be buffered and therefore delayed to
+ * the next wakeup. It's compromise of getting good enough latency when
+ * there's data traffic and still saving significantly power in idle
+ * periods.
+ *
+ * Dynamic powersave is simply supported by mac80211 enabling and disabling
+ * PS based on traffic. Driver needs to only set %IEEE80211_HW_SUPPORTS_PS
+ * flag and mac80211 will handle everything automatically. Additionally,
+ * hardware having support for the dynamic PS feature may set the
+ * %IEEE80211_HW_SUPPORTS_DYNAMIC_PS flag to indicate that it can support
+ * dynamic PS mode itself. The driver needs to look at the
+ * @dynamic_ps_timeout hardware configuration value and use it that value
+ * whenever %IEEE80211_CONF_PS is set. In this case mac80211 will disable
+ * dynamic PS feature in stack and will just keep %IEEE80211_CONF_PS
+ * enabled whenever user has enabled powersave.
+ *
+ * Driver informs U-APSD client support by enabling
+ * %IEEE80211_VIF_SUPPORTS_UAPSD flag. The mode is configured through the
+ * uapsd parameter in conf_tx() operation. Hardware needs to send the QoS
+ * Nullfunc frames and stay awake until the service period has ended. To
+ * utilize U-APSD, dynamic powersave is disabled for voip AC and all frames
+ * from that AC are transmitted with powersave enabled.
+ *
+ * Note: U-APSD client mode is not yet supported with
+ * %IEEE80211_HW_PS_NULLFUNC_STACK.
+ */
+
+/**
+ * DOC: Beacon filter support
+ *
+ * Some hardware have beacon filter support to reduce host cpu wakeups
+ * which will reduce system power consumption. It usually works so that
+ * the firmware creates a checksum of the beacon but omits all constantly
+ * changing elements (TSF, TIM etc). Whenever the checksum changes the
+ * beacon is forwarded to the host, otherwise it will be just dropped. That
+ * way the host will only receive beacons where some relevant information
+ * (for example ERP protection or WMM settings) have changed.
+ *
+ * Beacon filter support is advertised with the %IEEE80211_VIF_BEACON_FILTER
+ * interface capability. The driver needs to enable beacon filter support
+ * whenever power save is enabled, that is %IEEE80211_CONF_PS is set. When
+ * power save is enabled, the stack will not check for beacon loss and the
+ * driver needs to notify about loss of beacons with ieee80211_beacon_loss().
+ *
+ * The time (or number of beacons missed) until the firmware notifies the
+ * driver of a beacon loss event (which in turn causes the driver to call
+ * ieee80211_beacon_loss()) should be configurable and will be controlled
+ * by mac80211 and the roaming algorithm in the future.
+ *
+ * Since there may be constantly changing information elements that nothing
+ * in the software stack cares about, we will, in the future, have mac80211
+ * tell the driver which information elements are interesting in the sense
+ * that we want to see changes in them. This will include
+ * - a list of information element IDs
+ * - a list of OUIs for the vendor information element
+ *
+ * Ideally, the hardware would filter out any beacons without changes in the
+ * requested elements, but if it cannot support that it may, at the expense
+ * of some efficiency, filter out only a subset. For example, if the device
+ * doesn't support checking for OUIs it should pass up all changes in all
+ * vendor information elements.
+ *
+ * Note that change, for the sake of simplification, also includes information
+ * elements appearing or disappearing from the beacon.
+ *
+ * Some hardware supports an "ignore list" instead, just make sure nothing
+ * that was requested is on the ignore list, and include commonly changing
+ * information element IDs in the ignore list, for example 11 (BSS load) and
+ * the various vendor-assigned IEs with unknown contents (128, 129, 133-136,

+ * it could also include some currently unused IDs.
+ *
+ *
+ * In addition to these capabilities, hardware should support notifying the

+ * when no traffic is flowing (when traffic is flowing we see the RSSI of
+ * the received data packets). This can consist in notifying the host when
+ * the RSSI changes significantly or when it drops below or rises above
+ * configurable thresholds. In the future these thresholds will also be
+ * configured by mac80211 (which gets them from userspace) to implement
+ * them as the roaming algorithm requires.
+ *
+ * If the hardware cannot implement this, the driver should ask it to
+ * periodically pass beacon frames to the host so that software can do the
+ * signal strength threshold checking.

+ * DOC: Spatial multiplexing power save
+ *
+ * SMPS (Spatial multiplexing power save) is a mechanism to conserve

+ * and rationale, please refer to 802.11 (as amended by 802.11n-2009)
+ * "11.2.3 SM power save".
+ *
+ * The mac80211 implementation is capable of sending action frames
+ * to update the AP about the station's SMPS mode, and will instruct
+ * the driver to enter the specific mode. It will also announce the
+ * requested SMPS mode during the association handshake. Hardware
+ * support for this feature is required, and can be indicated by
+ * hardware flags.
+ *
+ * The default mode will be "automatic", which nl80211/cfg80211
+ * defines to be dynamic SMPS in (regular) powersave, and SMPS
+ * turned off otherwise.
+ *
+ * To support this feature, the driver must set the appropriate
+ * hardware support flags, and handle the SMPS flag to the config()
+ * operation. It will then with this mechanism be instructed to
+ * enter the requested SMPS mode while associated to an HT AP.

+/**
+ * DOC: Frame filtering
+ *
+ * mac80211 requires to see many management frames for proper
+ * operation, and users may want to see many more frames when
+ * in monitor mode. However, for best CPU usage and power consumption,
+ * having as few frames as possible percolate through the stack is
+ * desirable. Hence, the hardware should filter as much as possible.
+ *
+ * To achieve this, mac80211 uses filter flags (see below) to tell
+ * the driver's configure_filter() function which frames should be
+ * passed to mac80211 and which should be filtered out.
+ *
+ * Before configure_filter() is invoked, the prepare_multicast()
+ * callback is invoked with the parameters @mc_count and @mc_list
+ * for the combined multicast address list of all virtual interfaces.
+ * It's use is optional, and it returns a u64 that is passed to
+ * configure_filter(). Additionally, configure_filter() has the
+ * arguments @changed_flags telling which flags were changed and
+ * @total_flags with the new flag states.
+ *
+ * If your device has no multicast address filters your driver will
+ * need to check both the %FIF_ALLMULTI flag and the @mc_count
+ * parameter to see whether multicast frames should be accepted
+ * or dropped.
+ *
+ * All unsupported flags in @total_flags must be cleared.
+ * Hardware does not support a flag if it is incapable of _passing_
+ * the frame to the stack. Otherwise the driver must ignore
+ * the flag, but not clear it.
+ * You must _only_ clear the flag (announce no support for the
+ * flag to mac80211) if you are not able to pass the packet type
+ * to the stack (so the hardware always filters it).
+ * So for example, you should clear @FIF_CONTROL, if your hardware
+ * always filters control frames. If your hardware always passes
+ * control frames to the kernel and is incapable of filtering them,
+ * you do _not_ clear the @FIF_CONTROL flag.
+ * This rule applies to all other FIF flags as well.

+/**
+ * DOC: AP support for powersaving clients
+ *
+ * In order to implement AP and P2P GO modes, mac80211 has support for
+ * client powersaving, both "legacy" PS (PS-Poll/null data) and uAPSD.
+ * There currently is no support for sAPSD.
+ *
+ * There is one assumption that mac80211 makes, namely that a client
+ * will not poll with PS-Poll and trigger with uAPSD at the same time.
+ * Both are supported, and both can be used by the same client, but
+ * they can't be used concurrently by the same client. This simplifies
+ * the driver code.
+ *
+ * The first thing to keep in mind is that there is a flag for complete
+ * driver implementation: %IEEE80211_HW_AP_LINK_PS. If this flag is set,
+ * mac80211 expects the driver to handle most of the state machine for
+ * powersaving clients and will ignore the PM bit in incoming frames.
+ * Drivers then use ieee80211_sta_ps_transition() to inform mac80211 of
+ * stations' powersave transitions. In this mode, mac80211 also doesn't
+ * handle PS-Poll/uAPSD.
+ *
+ * In the mode without %IEEE80211_HW_AP_LINK_PS, mac80211 will check the
+ * PM bit in incoming frames for client powersave transitions. When a
+ * station goes to sleep, we will stop transmitting to it. There is,
+ * however, a race condition: a station might go to sleep while there is
+ * data buffered on hardware queues. If the device has support for this
+ * it will reject frames, and the driver should give the frames back to
+ * mac80211 with the %IEEE80211_TX_STAT_TX_FILTERED flag set which will
+ * cause mac80211 to retry the frame when the station wakes up. The
+ * driver is also notified of powersave transitions by calling its
+ * @sta_notify callback.
+ *
+ * When the station is asleep, it has three choices: it can wake up,
+ * it can PS-Poll, or it can possibly start a uAPSD service period.
+ * Waking up is implemented by simply transmitting all buffered (and
+ * filtered) frames to the station. This is the easiest case. When
+ * the station sends a PS-Poll or a uAPSD trigger frame, mac80211
+ * will inform the driver of this with the @allow_buffered_frames
+ * callback; this callback is optional. mac80211 will then transmit
+ * the frames as usual and set the %IEEE80211_TX_CTL_NO_PS_BUFFER
+ * on each frame. The last frame in the service period (or the only
+ * response to a PS-Poll) also has %IEEE80211_TX_STATUS_EOSP set to
+ * indicate that it ends the service period; as this frame must have
+ * TX status report it also sets %IEEE80211_TX_CTL_REQ_TX_STATUS.
+ * When TX status is reported for this frame, the service period is
+ * marked has having ended and a new one can be started by the peer.
+ *
+ * Additionally, non-bufferable MMPDUs can also be transmitted by
+ * mac80211 with the %IEEE80211_TX_CTL_NO_PS_BUFFER set in them.
+ *
+ * Another race condition can happen on some devices like iwlwifi
+ * when there are frames queued for the station and it wakes up
+ * or polls; the frames that are already queued could end up being
+ * transmitted first instead, causing reordering and/or wrong
+ * processing of the EOSP. The cause is that allowing frames to be
+ * transmitted to a certain station is out-of-band communication to
+ * the device. To allow this problem to be solved, the driver can
+ * call ieee80211_sta_block_awake() if frames are buffered when it
+ * is notified that the station went to sleep. When all these frames
+ * have been filtered (see above), it must call the function again
+ * to indicate that the station is no longer blocked.
+ *
+ * If the driver buffers frames in the driver for aggregation in any
+ * way, it must use the ieee80211_sta_set_buffered() call when it is
+ * notified of the station going to sleep to inform mac80211 of any
+ * TIDs that have frames buffered. Note that when a station wakes up
+ * this information is reset (hence the requirement to call it when
+ * informed of the station going to sleep). Then, when a service
+ * period starts for any reason, @release_buffered_frames is called
+ * with the number of frames to be released and which TIDs they are
+ * to come from. In this case, the driver is responsible for setting
+ * the EOSP (for uAPSD) and MORE_DATA bits in the released frames,
+ * to help the @more_data parameter is passed to tell the driver if
+ * there is more data on other TIDs -- the TIDs to release frames
+ * from are ignored since mac80211 doesn't know how many frames the
+ * buffers for those TIDs contain.
+ *
+ * If the driver also implement GO mode, where absence periods may
+ * shorten service periods (or abort PS-Poll responses), it must
+ * filter those response frames except in the case of frames that
+ * are buffered in the driver -- those must remain buffered to avoid
+ * reordering. Because it is possible that no frames are released
+ * in this case, the driver must call ieee80211_sta_eosp()
+ * to indicate to mac80211 that the service period ended anyway.
+ *
+ * Finally, if frames from multiple TIDs are released from mac80211
+ * but the driver might reorder them, it must clear & set the flags
+ * appropriately (only the last frame may have %IEEE80211_TX_STATUS_EOSP)
+ * and also take care of the EOSP and MORE_DATA bits in the frame.
+ * The driver may also use ieee80211_sta_eosp() in this case.
+ *
+ * Note that if the driver ever buffers frames other than QoS-data
+ * frames, it must take care to never send a non-QoS-data frame as
+ * the last frame in a service period, adding a QoS-nulldata frame
+ * after a non-QoS-data frame if needed.

+
+/**
+ * DOC: HW queue control
+ *
+ * Before HW queue control was introduced, mac80211 only had a single static
+ * assignment of per-interface AC software queues to hardware queues. This
+ * was problematic for a few reasons:
+ * 1) off-channel transmissions might get stuck behind other frames
+ * 2) multiple virtual interfaces couldn't be handled correctly
+ * 3) after-DTIM frames could get stuck behind other frames
+ *
+ * To solve this, hardware typically uses multiple different queues for all
+ * the different usages, and this needs to be propagated into mac80211 so it
+ * won't have the same problem with the software queues.
+ *
+ * Therefore, mac80211 now offers the %IEEE80211_HW_QUEUE_CONTROL capability
+ * flag that tells it that the driver implements its own queue control. To do
+ * so, the driver will set up the various queues in each &struct ieee80211_vif
+ * and the offchannel queue in &struct ieee80211_hw. In response, mac80211 will
+ * use those queue IDs in the hw_queue field of &struct ieee80211_tx_info and
+ * if necessary will queue the frame on the right software queue that mirrors
+ * the hardware queue.
+ * Additionally, the driver has to then use these HW queue IDs for the queue
+ * management functions (ieee80211_stop_queue() et al.)
+ *
+ * The driver is free to set up the queue mappings as needed, multiple virtual
+ * interfaces may map to the same hardware queues if needed. The setup has to
+ * happen during add_interface or change_interface callbacks. For example, a
+ * driver supporting station+station and station+AP modes might decide to have
+ * 10 hardware queues to handle different scenarios:
+ *
+ * 4 AC HW queues for 1st vif: 0, 1, 2, 3
+ * 4 AC HW queues for 2nd vif: 4, 5, 6, 7
+ * after-DTIM queue for AP: 8
+ * off-channel queue: 9
+ *
+ * It would then set up the hardware like this:
+ * hw.offchannel_tx_hw_queue = 9
+ *
+ * and the first virtual interface that is added as follows:
+ * vif.hw_queue[IEEE80211_AC_VO] = 0
+ * vif.hw_queue[IEEE80211_AC_VI] = 1
+ * vif.hw_queue[IEEE80211_AC_BE] = 2
+ * vif.hw_queue[IEEE80211_AC_BK] = 3
+ * vif.cab_queue = 8 // if AP mode, otherwise %IEEE80211_INVAL_HW_QUEUE
+ * and the second virtual interface with 4-7.
+ *
+ * If queue 6 gets full, for example, mac80211 would only stop the second
+ * virtual interface's BE queue since virtual interface queues are per AC.
+ *
+ * Note that the vif.cab_queue value should be set to %IEEE80211_INVAL_HW_QUEUE
+ * whenever the queue is not used (i.e. the interface is not in AP mode) if the
+ * queue could potentially be shared since mac80211 will look at cab_queue when
+ * a queue is stopped/woken even if the interface is not in AP mode.

+ *
+ * This structure contains various callbacks that the driver may
+ * handle or, in some cases, must handle, for example to configure
+ * the hardware to a new channel or to transmit a frame.
+ *
+ * @tx: Handler that 802.11 module calls for each transmitted frame.
+ * skb contains the buffer starting from the IEEE 802.11 header.
+ * The low-level driver should send the frame out based on
+ * configuration in the TX control data. This handler should,
+ * preferably, never fail and stop queues appropriately.
+ * Must be atomic.
+ *
+ * @start: Called before the first netdevice attached to the hardware
+ * is enabled. This should turn on the hardware and must turn on
+ * frame reception (for possibly enabled monitor interfaces.)
+ * Returns negative error codes, these may be seen in userspace,
+ * or zero.
+ * When the device is started it should not have a MAC address
+ * to avoid acknowledging frames before a non-monitor device
+ * is added.
+ * Must be implemented and can sleep.
+ *
+ * @stop: Called after last netdevice attached to the hardware
+ * is disabled. This should turn off the hardware (at least
+ * it must turn off frame reception.)
+ * May be called right after add_interface if that rejects
+ * an interface. If you added any work onto the mac80211 workqueue
+ * you should ensure to cancel it on this callback.
+ * Must be implemented and can sleep.
+ *
+ * @suspend: Suspend the device; mac80211 itself will quiesce before and
+ * stop transmitting and doing any other configuration, and then
+ * ask the device to suspend. This is only invoked when WoWLAN is
+ * configured, otherwise the device is deconfigured completely and
+ * reconfigured at resume time.
+ * The driver may also impose special conditions under which it
+ * wants to use the "normal" suspend (deconfigure), say if it only
+ * supports WoWLAN when the device is associated. In this case, it
+ * must return 1 from this function.
+ *
+ * @resume: If WoWLAN was configured, this indicates that mac80211 is
+ * now resuming its operation, after this the device must be fully
+ * functional again. If this returns an error, the only way out is
+ * to also unregister the device. If it returns 1, then mac80211
+ * will also go through the regular complete restart on resume.
+ *
+ * @set_wakeup: Enable or disable wakeup when WoWLAN configuration is
+ * modified. The reason is that device_set_wakeup_enable() is
+ * supposed to be called when the configuration changes, not only
+ * in suspend().
+ *
+ * @add_interface: Called when a netdevice attached to the hardware is
+ * enabled. Because it is not called for monitor mode devices, @start
+ * and @stop must be implemented.
+ * The driver should perform any initialization it needs before
+ * the device can be enabled. The initial configuration for the
+ * interface is given in the conf parameter.
+ * The callback may refuse to add an interface by returning a
+ * negative error code (which will be seen in userspace.)
+ * Must be implemented and can sleep.
+ *
+ * @change_interface: Called when a netdevice changes type. This callback
+ * is optional, but only if it is supported can interface types be
+ * switched while the interface is UP. The callback may sleep.
+ * Note that while an interface is being switched, it will not be
+ * found by the interface iteration callbacks.
+ *
+ * @remove_interface: Notifies a driver that an interface is going down.
+ * The @stop callback is called after this if it is the last interface
+ * and no monitor interfaces are present.
+ * When all interfaces are removed, the MAC address in the hardware
+ * must be cleared so the device no longer acknowledges packets,
+ * the mac_addr member of the conf structure is, however, set to the
+ * MAC address of the device going away.
+ * Hence, this callback must be implemented. It can sleep.
+ *
+ * @config: Handler for configuration requests. IEEE 802.11 code calls this
+ * function to change hardware configuration, e.g., channel.
+ * This function should never fail but returns a negative error code
+ * if it does. The callback can sleep.
+ *
+ * @bss_info_changed: Handler for configuration requests related to BSS
+ * parameters that may vary during BSS's lifespan, and may affect low
+ * level driver (e.g. assoc/disassoc status, erp parameters).
+ * This function should not be used if no BSS has been set, unless
+ * for association indication. The @changed parameter indicates which
+ * of the bss parameters has changed when a call is made. The callback
+ * can sleep.
+ *
+ * @prepare_multicast: Prepare for multicast filter configuration.
+ * This callback is optional, and its return value is passed
+ * to configure_filter(). This callback must be atomic.
+ *
+ * @configure_filter: Configure the device's RX filter.
+ * See the section "Frame filtering" for more information.
+ * This callback must be implemented and can sleep.
+ *
+ * @set_tim: Set TIM bit. mac80211 calls this function when a TIM bit
+ * must be set or cleared for a given STA. Must be atomic.
+ *
+ * @set_key: See the section "Hardware crypto acceleration"
+ * This callback is only called between add_interface and
+ * remove_interface calls, i.e. while the given virtual interface
+ * is enabled.
+ * Returns a negative error code if the key can't be added.
+ * The callback can sleep.
+ *
+ * @update_tkip_key: See the section "Hardware crypto acceleration"
+ * This callback will be called in the context of Rx. Called for drivers
+ * which set IEEE80211_KEY_FLAG_TKIP_REQ_RX_P1_KEY.
+ * The callback must be atomic.
+ *
+ * @set_rekey_data: If the device supports GTK rekeying, for example while the
+ * host is suspended, it can assign this callback to retrieve the data
+ * necessary to do GTK rekeying, this is the KEK, KCK and replay counter.
+ * After rekeying was done it should (for example during resume) notify
+ * userspace of the new replay counter using ieee80211_gtk_rekey_notify().
+ *
+ * @set_default_unicast_key: Set the default (unicast) key index, useful for
+ * WEP when the device sends data packets autonomously, e.g. for ARP
+ * offloading. The index can be 0-3, or -1 for unsetting it.
+ *
+ * @hw_scan: Ask the hardware to service the scan request, no need to start
+ * the scan state machine in stack. The scan must honour the channel
+ * configuration done by the regulatory agent in the wiphy's
+ * registered bands. The hardware (or the driver) needs to make sure
+ * that power save is disabled.
+ * The @req ie/ie_len members are rewritten by mac80211 to contain the
+ * entire IEs after the SSID, so that drivers need not look at these
+ * at all but just send them after the SSID -- mac80211 includes the
+ * (extended) supported rates and HT information (where applicable).
+ * When the scan finishes, ieee80211_scan_completed() must be called;
+ * note that it also must be called when the scan cannot finish due to
+ * any error unless this callback returned a negative error code.
+ * The callback can sleep.
+ *
+ * @cancel_hw_scan: Ask the low-level tp cancel the active hw scan.
+ * The driver should ask the hardware to cancel the scan (if possible),
+ * but the scan will be completed only after the driver will call
+ * ieee80211_scan_completed().
+ * This callback is needed for wowlan, to prevent enqueueing a new
+ * scan_work after the low-level driver was already suspended.
+ * The callback can sleep.
+ *
+ * @sched_scan_start: Ask the hardware to start scanning repeatedly at
+ * specific intervals. The driver must call the
+ * ieee80211_sched_scan_results() function whenever it finds results.
+ * This process will continue until sched_scan_stop is called.
+ *
+ * @sched_scan_stop: Tell the hardware to stop an ongoing scheduled scan.
+ * In this case, ieee80211_sched_scan_stopped() must not be called.
+ *
+ * @sw_scan_start: Notifier function that is called just before a software scan
+ * is started. Can be NULL, if the driver doesn't need this notification.
+ * The mac_addr parameter allows supporting NL80211_SCAN_FLAG_RANDOM_ADDR,
+ * the driver may set the NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR flag if it
+ * can use this parameter. The callback can sleep.
+ *
+ * @sw_scan_complete: Notifier function that is called just after a
+ * software scan finished. Can be NULL, if the driver doesn't need
+ * this notification.
+ * The callback can sleep.
+ *
+ * @get_stats: Return low-level statistics.
+ * Returns zero if statistics are available.
+ * The callback can sleep.
+ *
+ * @get_tkip_seq: If your device implements TKIP encryption in hardware this
+ * callback should be provided to read the TKIP transmit IVs (both IV32
+ * and IV16) for the given key from hardware.
+ * The callback must be atomic.
+ *
+ * @set_frag_threshold: Configuration of fragmentation threshold. Assign this
+ * if the device does fragmentation by itself; if this callback is
+ * implemented then the stack will not do fragmentation.
+ * The callback can sleep.
+ *
+ * @set_rts_threshold: Configuration of RTS threshold (if device needs it)
+ * The callback can sleep.
+ *
+ * @sta_add: Notifies low level driver about addition of an associated station,
+ * AP, IBSS/WDS/mesh peer etc. This callback can sleep.
+ *
+ * @sta_remove: Notifies low level driver about removal of an associated
+ * station, AP, IBSS/WDS/mesh peer etc. Note that after the callback
+ * returns it isn't safe to use the pointer, not even RCU protected;
+ * no RCU grace period is guaranteed between returning here and freeing
+ * the station. See @sta_pre_rcu_remove if needed.
+ * This callback can sleep.
+ *
+ * @sta_add_debugfs: Drivers can use this callback to add debugfs files
+ * when a station is added to mac80211's station list. This callback
+ * and @sta_remove_debugfs should be within a CONFIG_MAC80211_DEBUGFS
+ * conditional. This callback can sleep.
+ *
+ * @sta_remove_debugfs: Remove the debugfs files which were added using
+ * @sta_add_debugfs. This callback can sleep.
+ *
+ * @sta_notify: Notifies low level driver about power state transition of an
+ * associated station, AP, IBSS/WDS/mesh peer etc. For a VIF operating
+ * in AP mode, this callback will not be called when the flag
+ * %IEEE80211_HW_AP_LINK_PS is set. Must be atomic.
+ *
+ * @sta_state: Notifies low level driver about state transition of a
+ * station (which can be the AP, a client, IBSS/WDS/mesh peer etc.)
+ * This callback is mutually exclusive with @sta_add/@sta_remove.
+ * It must not fail for down transitions but may fail for transitions
+ * up the list of states. Also note that after the callback returns it
+ * isn't safe to use the pointer, not even RCU protected - no RCU grace
+ * period is guaranteed between returning here and freeing the station.
+ * See @sta_pre_rcu_remove if needed.
+ * The callback can sleep.
+ *
+ * @sta_pre_rcu_remove: Notify driver about station removal before RCU
+ * synchronisation. This is useful if a driver needs to have station
+ * pointers protected using RCU, it can then use this call to clear
+ * the pointers instead of waiting for an RCU grace period to elapse
+ * in @sta_state.
+ * The callback can sleep.
+ *
+ * @sta_rc_update: Notifies the driver of changes to the bitrates that can be
+ * used to transmit to the station. The changes are advertised with bits
+ * from &enum ieee80211_rate_control_changed and the values are reflected
+ * in the station data. This callback should only be used when the driver
+ * uses hardware rate control (%IEEE80211_HW_HAS_RATE_CONTROL) since
+ * otherwise the rate control algorithm is notified directly.
+ * Must be atomic.
+ * @sta_rate_tbl_update: Notifies the driver that the rate table changed. This
+ * is only used if the configured rate control algorithm actually uses
+ * the new rate table API, and is therefore optional. Must be atomic.
+ *
+ * @sta_statistics: Get statistics for this station. For example with beacon
+ * filtering, the statistics kept by mac80211 might not be accurate, so
+ * let the driver pre-fill the statistics. The driver can fill most of
+ * the values (indicating which by setting the filled bitmap), but not
+ * all of them make sense - see the source for which ones are possible.
+ * Statistics that the driver doesn't fill will be filled by mac80211.
+ * The callback can sleep.
+ *
+ * @conf_tx: Configure TX queue parameters (EDCF (aifs, cw_min, cw_max),
+ * bursting) for a hardware TX queue.
+ * Returns a negative error code on failure.
+ * The callback can sleep.
+ *
+ * @get_tsf: Get the current TSF timer value from firmware/hardware. Currently,
+ * this is only used for IBSS mode BSSID merging and debugging. Is not a
+ * required function.
+ * The callback can sleep.
+ *
+ * @set_tsf: Set the TSF timer to the specified value in the firmware/hardware.
+ * Currently, this is only used for IBSS mode debugging. Is not a
+ * required function.
+ * The callback can sleep.
+ *
+ * @reset_tsf: Reset the TSF timer and allow firmware/hardware to synchronize
+ * with other STAs in the IBSS. This is only used in IBSS mode. This
+ * function is optional if the firmware/hardware takes full care of
+ * TSF synchronization.
+ * The callback can sleep.
+ *
+ * @tx_last_beacon: Determine whether the last IBSS beacon was sent by us.
+ * This is needed only for IBSS mode and the result of this function is
+ * used to determine whether to reply to Probe Requests.
+ * Returns non-zero if this device sent the last beacon.
+ * The callback can sleep.
+ *
+ * @ampdu_action: Perform a certain A-MPDU action
+ * The RA/TID combination determines the destination and TID we want
+ * the ampdu action to be performed for. The action is defined through
+ * ieee80211_ampdu_mlme_action. Starting sequence number (@ssn)
+ * is the first frame we expect to perform the action on. Notice
+ * that TX/RX_STOP can pass NULL for this parameter.
+ * The @buf_size parameter is only valid when the action is set to
+ * %IEEE80211_AMPDU_TX_OPERATIONAL and indicates the peer's reorder
+ * buffer size (number of subframes) for this session -- the driver
+ * may neither send aggregates containing more subframes than this
+ * nor send aggregates in a way that lost frames would exceed the
+ * buffer size. If just limiting the aggregate size, this would be
+ * possible with a buf_size of 8:
+ * - TX: 1.....7
+ * - RX: 2....7 (lost frame #1)
+ * - TX: 8..1...
+ * which is invalid since #1 was now re-transmitted well past the
+ * buffer size of 8. Correct ways to retransmit #1 would be:
+ * - TX: 1 or 18 or 81
+ * Even "189" would be wrong since 1 could be lost again.
+ *
+ * Returns a negative error code on failure.
+ * The callback can sleep.
+ *
+ * @get_survey: Return per-channel survey information
+ *
+ * @rfkill_poll: Poll rfkill hardware state. If you need this, you also
+ * need to set wiphy->rfkill_poll to %true before registration,
+ * and need to call wiphy_rfkill_set_hw_state() in the callback.
+ * The callback can sleep.
+ *
+ * @set_coverage_class: Set slot time for given coverage class as specified
+ * in IEEE 802.11-2007 section 17.3.8.6 and modify ACK timeout
+ * accordingly; coverage class equals to -1 to enable ACK timeout
+ * estimation algorithm (dynack). To disable dynack set valid value for
+ * coverage class. This callback is not required and may sleep.
+ *
+ * @testmode_cmd: Implement a cfg80211 test mode command. The passed @vif may
+ * be %NULL. The callback can sleep.
+ * @testmode_dump: Implement a cfg80211 test mode dump. The callback can sleep.
+ *
+ * @flush: Flush all pending frames from the hardware queue, making sure
+ * that the hardware queues are empty. The @queues parameter is a bitmap
+ * of queues to flush, which is useful if different virtual interfaces
+ * use different hardware queues; it may also indicate all queues.
+ * If the parameter @drop is set to %true, pending frames may be dropped.
+ * Note that vif can be NULL.
+ * The callback can sleep.
+ *
+ * @channel_switch: Drivers that need (or want) to offload the channel
+ * switch operation for CSAs received from the AP may implement this
+ * callback. They must then call ieee80211_chswitch_done() to indicate
+ * completion of the channel switch.
+ *
+ * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
+ * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
+ * reject TX/RX mask combinations they cannot support by returning -EINVAL
+ * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
+ *
+ * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
+ *
+ * @remain_on_channel: Starts an off-channel period on the given channel, must
+ * call back to ieee80211_ready_on_channel() when on that channel. Note
+ * that normal channel traffic is not stopped as this is intended for hw
+ * offload. Frames to transmit on the off-channel channel are transmitted
+ * normally except for the %IEEE80211_TX_CTL_TX_OFFCHAN flag. When the
+ * duration (which will always be non-zero) expires, the driver must call
+ * ieee80211_remain_on_channel_expired().
+ * Note that this callback may be called while the device is in IDLE and
+ * must be accepted in this case.
+ * This callback may sleep.
+ * @cancel_remain_on_channel: Requests that an ongoing off-channel period is
+ * aborted before it expires. This callback may sleep.
+ *
+ * @set_ringparam: Set tx and rx ring sizes.
+ *
+ * @get_ringparam: Get tx and rx ring current and maximum sizes.
+ *
+ * @tx_frames_pending: Check if there is any pending frame in the hardware
+ * queues before entering power save.
+ *
+ * @set_bitrate_mask: Set a mask of rates to be used for rate control selection
+ * when transmitting a frame. Currently only legacy rates are handled.
+ * The callback can sleep.
+ * @event_callback: Notify driver about any event in mac80211. See
+ * &enum ieee80211_event_type for the different types.
+ * The callback can sleep.
+ *
+ * @release_buffered_frames: Release buffered frames according to the given
+ * parameters. In the case where the driver buffers some frames for
+ * sleeping stations mac80211 will use this callback to tell the driver
+ * to release some frames, either for PS-poll or uAPSD.
+ * Note that if the @more_data parameter is %false the driver must check
+ * if there are more frames on the given TIDs, and if there are more than
+ * the frames being released then it must still set the more-data bit in
+ * the frame. If the @more_data parameter is %true, then of course the
+ * more-data bit must always be set.
+ * The @tids parameter tells the driver which TIDs to release frames
+ * from, for PS-poll it will always have only a single bit set.
+ * In the case this is used for a PS-poll initiated release, the
+ * @num_frames parameter will always be 1 so code can be shared. In
+ * this case the driver must also set %IEEE80211_TX_STATUS_EOSP flag
+ * on the TX status (and must report TX status) so that the PS-poll
+ * period is properly ended. This is used to avoid sending multiple
+ * responses for a retried PS-poll frame.
+ * In the case this is used for uAPSD, the @num_frames parameter may be
+ * bigger than one, but the driver may send fewer frames (it must send
+ * at least one, however). In this case it is also responsible for
+ * setting the EOSP flag in the QoS header of the frames. Also, when the
+ * service period ends, the driver must set %IEEE80211_TX_STATUS_EOSP
+ * on the last frame in the SP. Alternatively, it may call the function
+ * ieee80211_sta_eosp() to inform mac80211 of the end of the SP.
+ * This callback must be atomic.
+ * @allow_buffered_frames: Prepare device to allow the given number of frames
+ * to go out to the given station. The frames will be sent by mac80211
+ * via the usual TX path after this call. The TX information for frames
+ * released will also have the %IEEE80211_TX_CTL_NO_PS_BUFFER flag set
+ * and the last one will also have %IEEE80211_TX_STATUS_EOSP set. In case
+ * frames from multiple TIDs are released and the driver might reorder
+ * them between the TIDs, it must set the %IEEE80211_TX_STATUS_EOSP flag
+ * on the last frame and clear it on all others and also handle the EOSP
+ * bit in the QoS header correctly. Alternatively, it can also call the
+ * ieee80211_sta_eosp() function.
+ * The @tids parameter is a bitmap and tells the driver which TIDs the
+ * frames will be on; it will at most have two bits set.
+ * This callback must be atomic.
+ *
+ * @get_et_sset_count: Ethtool API to get string-set count.
+ *
+ * @get_et_stats: Ethtool API to get a set of u64 stats.
+ *
+ * @get_et_strings: Ethtool API to get a set of strings to describe stats
+ * and perhaps other supported types of ethtool data-sets.
+ *
+ * @mgd_prepare_tx: Prepare for transmitting a management frame for association
+ * before associated. In multi-channel scenarios, a virtual interface is
+ * bound to a channel before it is associated, but as it isn't associated
+ * yet it need not necessarily be given airtime, in particular since any
+ * transmission to a P2P GO needs to be synchronized against the GO's
+ * powersave state. mac80211 will call this function before transmitting a
+ * management frame prior to having successfully associated to allow the
+ * driver to give it channel time for the transmission, to get a response
+ * and to be able to synchronize with the GO.
+ * The callback will be called before each transmission and upon return
+ * mac80211 will transmit the frame right away.
+ * The callback is optional and can (should!) sleep.
+ *
+ * @mgd_protect_tdls_discover: Protect a TDLS discovery session. After sending
+ * a TDLS discovery-request, we expect a reply to arrive on the AP's
+ * channel. We must stay on the channel (no PSM, scan, etc.), since a TDLS
+ * setup-response is a direct packet not buffered by the AP.
+ * mac80211 will call this function just before the transmission of a TDLS
+ * discovery-request. The recommended period of protection is at least
+ * 2 * (DTIM period).
+ * The callback is optional and can sleep.
+ *
+ * @add_chanctx: Notifies device driver about new channel context creation.
+ * @remove_chanctx: Notifies device driver about channel context destruction.
+ * @change_chanctx: Notifies device driver about channel context changes that
+ * may happen when combining different virtual interfaces on the same
+ * channel context with different settings
+ * @assign_vif_chanctx: Notifies device driver about channel context being bound
+ * to vif. Possible use is for hw queue remapping.
+ * @unassign_vif_chanctx: Notifies device driver about channel context being
+ * unbound from vif.
+ * @switch_vif_chanctx: switch a number of vifs from one chanctx to
+ * another, as specified in the list of
+ * @ieee80211_vif_chanctx_switch passed to the driver, according
+ * to the mode defined in &ieee80211_chanctx_switch_mode.
+ *
+ * @start_ap: Start operation on the AP interface, this is called after all the
+ * information in bss_conf is set and beacon can be retrieved. A channel
+ * context is bound before this is called. Note that if the driver uses
+ * software scan or ROC, this (and @stop_ap) isn't called when the AP is
+ * just "paused" for scanning/ROC, which is indicated by the beacon being
+ * disabled/enabled via @bss_info_changed.
+ * @stop_ap: Stop operation on the AP interface.
+ *
+ * @reconfig_complete: Called after a call to ieee80211_restart_hw() and
+ * during resume, when the reconfiguration has completed.
+ * This can help the driver implement the reconfiguration step (and
+ * indicate mac80211 is ready to receive frames).
+ * This callback may sleep.
+ *
+ * @ipv6_addr_change: IPv6 address assignment on the given interface changed.
+ * Currently, this is only called for managed or P2P client interfaces.
+ * This callback is optional; it must not sleep.
+ *
+ * @channel_switch_beacon: Starts a channel switch to a new channel.
+ * Beacons are modified to include CSA or ECSA IEs before calling this
+ * function. The corresponding count fields in these IEs must be
+ * decremented, and when they reach 1 the driver must call
+ * ieee80211_csa_finish(). Drivers which use ieee80211_beacon_get()
+ * get the csa counter decremented by mac80211, but must check if it is
+ * 1 using ieee80211_csa_is_complete() after the beacon has been
+ * transmitted and then call ieee80211_csa_finish().
+ * If the CSA count starts as zero or 1, this function will not be called,
+ * since there won't be any time to beacon before the switch anyway.
+ * @pre_channel_switch: This is an optional callback that is called
+ * before a channel switch procedure is started (ie. when a STA
+ * gets a CSA or an userspace initiated channel-switch), allowing
+ * the driver to prepare for the channel switch.
+ * @post_channel_switch: This is an optional callback that is called
+ * after a channel switch procedure is completed, allowing the
+ * driver to go back to a normal configuration.
+ *
+ * @join_ibss: Join an IBSS (on an IBSS interface); this is called after all
+ * information in bss_conf is set up and the beacon can be retrieved. A
+ * channel context is bound before this is called.
+ * @leave_ibss: Leave the IBSS again.
+ *
+ * @get_expected_throughput: extract the expected throughput towards the
+ * specified station. The returned value is expressed in Kbps. It returns 0
+ * if the RC algorithm does not have proper data to provide.
+ *
+ * @get_txpower: get current maximum tx power (in dBm) based on configuration
+ * and hardware limits.
+ *
+ * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
+ * is responsible for continually initiating channel-switching operations
+ * and returning to the base channel for communication with the AP. The
+ * driver receives a channel-switch request template and the location of
+ * the switch-timing IE within the template as part of the invocation.
+ * The template is valid only within the call, and the driver can
+ * optionally copy the skb for further re-use.
+ * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
+ * peers must be on the base channel when the call completes.
+ * @tdls_recv_channel_switch: a TDLS channel-switch related frame (request or
+ * response) has been received from a remote peer. The driver gets
+ * parameters parsed from the incoming frame and may use them to continue
+ * an ongoing channel-switch operation. In addition, a channel-switch
+ * response template is provided, together with the location of the
+ * switch-timing IE within the template. The skb can only be used within
+ * the function call.
+ *
+ * @wake_tx_queue: Called when new packets have been added to the queue.

+ * inside the kernel; NetLabel provides a mechanism for user space applications
+ * to manage these mapping tables.
+ *
+ * NetLabel makes use of the Generic NETLINK mechanism as a transport layer to
+ * send messages between kernel and user space. The general format of a
+ * NetLabel message is shown below:
+ *
+ * +-----------------+-------------------+--------- --- -- -
+ * | struct nlmsghdr | struct genlmsghdr | payload
+ * +-----------------+-------------------+--------- --- -- -
+ *
+ * The 'nlmsghdr' and 'genlmsghdr' structs should be dealt with like normal.
+ * The payload is dependent on the subsystem specified in the
+ * 'nlmsghdr->nlmsg_type' and should be defined below, supporting functions
+ * should be defined in the corresponding net/netlabel/netlabel_<subsys>.h|c
+ * file. All of the fields in the NetLabel payload are NETLINK attributes, see

+ * previously set with in_configure_hw. The peer response is returned
+ * through callback cb. If an io error occurs or the peer didn't reply
+ * within the specified timeout (ms), the error code is passed back through
+ * the resp pointer. This is an asynchronous function.
+ *
+ * Target mode: Only NFC-DEP protocol is supported in target mode.
+ * @tg_configure_hw: Hardware configuration for RF technology and communication
+ * framing in target mode. This is a synchronous function.
+ * @tg_send_cmd: Target mode data exchange using RF technology and framing
+ * previously set with tg_configure_hw. The peer next command is returned
+ * through callback cb. If an io error occurs or the peer didn't reply
+ * within the specified timeout (ms), the error code is passed back through
+ * the resp pointer. This is an asynchronous function.
+ * @tg_listen: Put the device in listen mode waiting for data from the peer
+ * device. This is an asynchronous function.
+ * @tg_listen_mdaa: If supported, put the device in automatic listen mode with
+ * mode detection and automatic anti-collision. In this mode, the device
+ * automatically detects the RF technology and executes the anti-collision
+ * detection using the command responses specified in mdaa_params. The
+ * mdaa_params structure contains SENS_RES, NFCID1, and SEL_RES for 106A RF
+ * tech. NFCID2 and system code (sc) for 212F and 424F. The driver returns
+ * the NFC-DEP ATR_REQ command through cb. The digital stack deducts the RF
+ * tech by analyzing the SoD of the frame containing the ATR_REQ command.
+ * This is an asynchronous function.
+ * @tg_listen_md: If supported, put the device in automatic listen mode with
+ * mode detection but without automatic anti-collision. In this mode, the
+ * device automatically detects the RF technology. What the actual
+ * RF technology is can be retrieved by calling @tg_get_rf_tech.
+ * The digital stack will then perform the appropriate anti-collision
+ * sequence. This is an asynchronous function.
+ * @tg_get_rf_tech: Required when @tg_listen_md is supported, unused otherwise.
+ * Return the RF Technology that was detected by the @tg_listen_md call.
+ * This is a synchronous function.
+ *
+ * @switch_rf: Turns device radio on or off. The stack does not call explicitly
+ * switch_rf to turn the radio on. A call to in|tg_configure_hw must turn
+ * the device radio on.
+ * @abort_cmd: Discard the last sent command.
+ *
+ * Notes: Asynchronous functions have a timeout parameter. It is the driver
+ * responsibility to call the digital stack back through the
+ * nfc_digital_cmd_complete_t callback when no RF respsonse has been
+ * received within the specified time (in milliseconds). In that case the
+ * driver must set the resp sk_buff to ERR_PTR(-ETIMEDOUT).
+ * Since the digital stack serializes commands to be sent, it's mandatory
+ * for the driver to handle the timeout correctly. Otherwise the stack
+ * would not be able to send new commands, waiting for the reply of the
+ * current one.

+/* Random Early Detection (RED) algorithm.
+ =======================================
+
+ Source: Sally Floyd and Van Jacobson, "Random Early Detection Gateways
+ for Congestion Avoidance", 1993, IEEE/ACM Transactions on Networking.
+
+ This file codes a "divisionless" version of RED algorithm
+ as written down in Fig.17 of the paper.
+
+ Short description.
+ ------------------
+
+ When a new packet arrives we calculate the average queue length:
+
+ avg = (1-W)*avg + W*current_queue_len,
+
+ W is the filter time constant (chosen as 2^(-Wlog)), it controls
+ the inertia of the algorithm. To allow larger bursts, W should be
+ decreased.
+
+ if (avg > th_max) -> packet marked (dropped).
+ if (avg < th_min) -> packet passes.
+ if (th_min < avg < th_max) we calculate probability:
+
+ Pb = max_P * (avg - th_min)/(th_max-th_min)
+
+ and mark (drop) packet with this probability.
+ Pb changes from 0 (at avg==th_min) to max_P (avg==th_max).
+ max_P should be small (not 1), usually 0.01..0.02 is good value.
+
+ max_P is chosen as a number, so that max_P/(th_max-th_min)
+ is a negative power of two in order arithmetics to contain
+ only shifts.
+
+
+ Parameters, settable by user:
+ -----------------------------
+
+ qth_min - bytes (should be < qth_max/2)
+ qth_max - bytes (should be at least 2*qth_min and less limit)
+ Wlog - bits (<32) log(1/W).
+ Plog - bits (<32)
+
+ Plog is related to max_P by formula:
+
+ max_P = (qth_max-qth_min)/2^Plog;
+
+ F.e. if qth_max=128K and qth_min=32K, then Plog=22
+ corresponds to max_P=0.02
+
+ Scell_log
+ Stab
+
+ Lookup table for log((1-W)^(t/t_ave).
+
+
+ NOTES:
+
+ Upper bound on W.
+ -----------------
+
+ If you want to allow bursts of L packets of size S,
+ you should choose W:
+
+ L + 1 - th_min/S < (1-(1-W)^L)/W
+
+ th_min/S = 32 th_min/S = 4
+
+ log(W) L

+ -3 39
+ -4 46
+ -5 57

+ * we will disregard the first regulatory hint (when the
+ * initiator is %REGDOM_SET_BY_CORE). Drivers that use
+ * wiphy_apply_custom_regulatory() should have this flag set
+ * or the regulatory core will set it for the wiphy.

+ * wiphy_apply_custom_regulatory() the wireless core will
+ * clear the REGULATORY_CUSTOM_REG for your wiphy as it would be
+ * implied that the device somehow gained knowledge of its region.
+ * @REGULATORY_STRICT_REG: tells us that the wiphy for this device
+ * has regulatory domain that it wishes to be considered as the
+ * superset for regulatory rules. After this device gets its regulatory
+ * domain programmed further regulatory hints shall only be considered
+ * for this device to enhance regulatory compliance, forcing the
+ * device to only possibly use subsets of the original regulatory
+ * rules. For example if channel 13 and 14 are disabled by this
+ * device's regulatory domain no user specified regulatory hint which
+ * has these channels enabled would enable them for this wiphy,
+ * the device's original regulatory domain will be trusted as the
+ * base. You can program the superset of regulatory rules for this
+ * wiphy with regulatory_hint() for cards programmed with an
+ * ISO3166-alpha2 country code. wiphys that use regulatory_hint()
+ * will have their wiphy->regd programmed once the regulatory
+ * domain is set, and all other regulatory hints will be ignored
+ * until their own regulatory domain gets programmed.
+ * @REGULATORY_DISABLE_BEACON_HINTS: enable this if your driver needs to
+ * ensure that passive scan flags and beaconing flags may not be lifted by
+ * cfg80211 due to regulatory beacon hints. For more information on beacon
+ * hints read the documenation for regulatory_hint_found_beacon()
+ * @REGULATORY_COUNTRY_IE_FOLLOW_POWER: for devices that have a preference
+ * that even though they may have programmed their own custom power
+ * setting prior to wiphy registration, they want to ensure their channel
+ * power settings are updated for this connection with the power settings
+ * derived from the regulatory domain. The regulatory domain used will be
+ * based on the ISO3166-alpha2 from country IE provided through
+ * regulatory_hint_country_ie()
+ * @REGULATORY_COUNTRY_IE_IGNORE: for devices that have a preference to ignore
+ * all country IE information processed by the regulatory core. This will
+ * override %REGULATORY_COUNTRY_IE_FOLLOW_POWER as all country IEs will
+ * be ignored.
+ * @REGULATORY_ENABLE_RELAX_NO_IR: for devices that wish to allow the
+ * NO_IR relaxation, which enables transmissions on channels on which
+ * otherwise initiating radiation is not allowed. This will enable the
+ * relaxations enabled under the CFG80211_REG_RELAX_NO_IR configuration
+ * option
+ * @REGULATORY_IGNORE_STALE_KICKOFF: the regulatory core will _not_ make sure
+ * all interfaces on this wiphy reside on allowed channels. If this flag
+ * is not set, upon a regdomain change, the interfaces are given a grace
+ * period (currently 60 seconds) to disconnect or move to an allowed
+ * channel. Interfaces on forbidden channels are forcibly disconnected.
+ * Currently these types of interfaces are supported for enforcement:
+ * NL80211_IFTYPE_ADHOC, NL80211_IFTYPE_STATION, NL80211_IFTYPE_AP,
+ * NL80211_IFTYPE_AP_VLAN, NL80211_IFTYPE_MONITOR,
+ * NL80211_IFTYPE_P2P_CLIENT, NL80211_IFTYPE_P2P_GO,
+ * NL80211_IFTYPE_P2P_DEVICE. The flag will be set by default if a device
+ * includes any modes unsupported for enforcement checking.
+ * @REGULATORY_WIPHY_SELF_MANAGED: for devices that employ wiphy-specific
+ * regdom management. These devices will ignore all regdom changes not
+ * originating from their own wiphy.
+ * A self-managed wiphys only employs regulatory information obtained from
+ * the FW and driver and does not use other cfg80211 sources like
+ * beacon-hints, country-code IEs and hints from other devices on the same
+ * system. Conversely, a self-managed wiphy does not share its regulatory

+ * conversation number that associates a saved IP/TCP header with

+ * sequence number changes, one change per bit set in the header
+ * (there may be no changes and there are two special cases where
+ * the receiver implicitly knows what changed -- see below).
+ *
+ * There are 5 numbers which can change (they are always inserted
+ * in the following order): TCP urgent pointer, window,
+ * acknowledgment, sequence number and IP ID. (The urgent pointer
+ * is different from the others in that its value is sent, not the
+ * change in value.) Since typical use of SLIP links is biased
+ * toward small packets (see comments on MTU/MSS below), changes
+ * use a variable length coding with one octet for numbers in the
+ * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the

+ * control flags set); uncompressed TCP (a normal IP/TCP packet but
+ * with the 8-bit protocol field replaced by an 8-bit connection id --
+ * this type of packet syncs the sender & receiver); and compressed
+ * TCP (described above).
+ *
+ * LSB of 4-bit field is TCP "PUSH" bit (a worthless anachronism) and
+ * is logically part of the 4-bit "changes" field that follows. Top
+ * three bits are actual packet type. For backward compatibility
+ * and in the interest of conserving bits, numbers are chosen so the
+ * IP protocol version number (4) which normally appears in this nibble

+ * INET An implementation of the TCP/IP protocol suite for the LINUX

+ * Corey Minyard <wf-rch!minyard@relay.EU.net>
+ * Florian La Roche <flla@stud.uni-sb.de>
+ *
+ * Fixes:
+ * Alan Cox : Volatiles in skbuff pointers. See
+ * skbuff comments. May be overdone,
+ * better to prove they can be removed
+ * than the reverse.
+ * Alan Cox : Added a zapped field for tcp to note
+ * a socket is reset and must stay shut up
+ * Alan Cox : New fields for options
+ * Pauline Middelink : identd support
+ * Alan Cox : Eliminate low level recv/recvfrom
+ * David S. Miller : New socket lookup architecture.
+ * Steve Whitehouse: Default routines for sock_ops
+ * Arnaldo C. Melo : removed net_pinfo, tp_pinfo and made
+ * protinfo be just a void pointer, as the
+ * protocol specific parts were moved to
+ * respective headers and ipv4/v6, etc now
+ * use private slabcaches for its socks

+ *
+ *
+ * The WiMAX stack provides an API for controlling and managing the
+ * system's WiMAX devices. This API affects the control plane; the
+ * data plane is accessed via the network stack (netdev).
+ *
+ * Parts of the WiMAX stack API and notifications are exported to
+ * user space via Generic Netlink. In user space, libwimax (part of
+ * the wimax-tools package) provides a shim layer for accessing those
+ * calls.
+ *
+ * The API is standarized for all WiMAX devices and different drivers
+ * implement the backend support for it. However, device-specific
+ * messaging pipes are provided that can be used to issue commands and
+ * receive notifications in free form.
+ *
+ * Currently the messaging pipes are the only means of control as it
+ * is not known (due to the lack of more devices in the market) what
+ * will be a good abstraction layer. Expect this to change as more
+ * devices show in the market. This API is designed to be growable in
+ * order to address this problem.
+ *
+ * USAGE
+ *
+ * Embed a `struct wimax_dev` at the beginning of the the device's
+ * private structure, initialize and register it. For details, see
+ * `struct wimax_dev`s documentation.
+ *
+ * Once this is done, wimax-tools's libwimaxll can be used to
+ * communicate with the driver from user space. You user space
+ * application does not have to forcibily use libwimaxll and can talk
+ * the generic netlink protocol directly if desired.
+ *
+ * Remember this is a very low level API that will to provide all of
+ * WiMAX features. Other daemons and services running in user space
+ * are the expected clients of it. They offer a higher level API that
+ * applications should use (an example of this is the Intel's WiMAX
+ * Network Service for the i2400m).
+ *
+ * DESIGN
+ *
+ * Although not set on final stone, this very basic interface is
+ * mostly completed. Remember this is meant to grow as new common
+ * operations are decided upon. New operations will be added to the
+ * interface, intent being on keeping backwards compatibility as much
+ * as possible.
+ *
+ * This layer implements a set of calls to control a WiMAX device,
+ * exposing a frontend to the rest of the kernel and user space (via
+ * generic netlink) and a backend implementation in the driver through
+ * function pointers.
+ *
+ * WiMAX devices have a state, and a kernel-only API allows the
+ * drivers to manipulate that state. State transitions are atomic, and
+ * only some of them are allowed (see `enum wimax_st`).
+ *
+ * Most API calls will set the state automatically; in most cases
+ * drivers have to only report state changes due to external
+ * conditions.
+ *
+ * All API operations are 'atomic', serialized through a mutex in the
+ * `struct wimax_dev`.
+ *
+ * EXPORTING TO USER SPACE THROUGH GENERIC NETLINK
+ *
+ * The API is exported to user space using generic netlink (other
+ * methods can be added as needed).
+ *
+ * There is a Generic Netlink Family named "WiMAX", where interfaces
+ * supporting the WiMAX interface receive commands and broadcast their
+ * signals over a multicast group named "msg".
+ *
+ * Mapping to the source/destination interface is done by an interface
+ * index attribute.
+ *
+ * For user-to-kernel traffic (commands) we use a function call
+ * marshalling mechanism, where a message X with attributes A, B, C
+ * sent from user space to kernel space means executing the WiMAX API
+ * call wimax_X(A, B, C), sending the results back as a message.
+ *
+ * Kernel-to-user (notifications or signals) communication is sent
+ * over multicast groups. This allows to have multiple applications
+ * monitoring them.
+ *
+ * Each command/signal gets assigned it's own attribute policy. This
+ * way the validator will verify that all the attributes in there are
+ * only the ones that should be for each command/signal. Thing of an
+ * attribute mapping to a type+argumentname for each command/signal.
+ *
+ * If we had a single policy for *all* commands/signals, after running
+ * the validator we'd have to check "does this attribute belong in
+ * here"? for each one. It can be done manually, but it's just easier
+ * to have the validator do that job with multiple policies. As well,
+ * it makes it easier to later expand each command/signal signature
+ * without affecting others and keeping the namespace more or less
+ * sane. Not that it is too complicated, but it makes it even easier.
+ *
+ * No state information is maintained in the kernel for each user
+ * space connection (the connection is stateless).
+ *
+ * TESTING FOR THE INTERFACE AND VERSIONING
+ *
+ * If network interface X is a WiMAX device, there will be a Generic
+ * Netlink family named "WiMAX X" and the device will present a
+ * "wimax" directory in it's network sysfs directory
+ * (/sys/class/net/DEVICE/wimax) [used by HAL].
+ *
+ * The inexistence of any of these means the device does not support
+ * this WiMAX API.
+ *
+ * By querying the generic netlink controller, versioning information
+ * and the multicast groups available can be found. Applications using
+ * the interface can either rely on that or use the generic netlink
+ * controller to figure out which generic netlink commands/signals are
+ * supported.
+ *
+ * NOTE: this versioning is a last resort to avoid hard
+ * incompatibilities. It is the intention of the design of this
+ * stack not to introduce backward incompatible changes.
+ *
+ * The version code has to fit in one byte (restrictions imposed by
+ * generic netlink); we use `version / 10` for the major version and
+ * `version % 10` for the minor. This gives 9 minors for each major
+ * and 25 majors.
+ *
+ * The version change protocol is as follow:
+ *
+ * - Major versions: needs to be increased if an existing message/API
+ * call is changed or removed. Doesn't need to be changed if a new
+ * message is added.
+ *
+ * - Minor version: needs to be increased if new messages/API calls are
+ * being added or some other consideration that doesn't impact the
+ * user-kernel interface too much (like some kind of bug fix) and
+ * that is kind of left up in the air to common sense.
+ *
+ * User space code should not try to work if the major version it was
+ * compiled for differs from what the kernel offers. As well, if the
+ * minor version of the kernel interface is lower than the one user
+ * space is expecting (the one it was compiled for), the kernel
+ * might be missing API calls; user space shall be ready to handle
+ * said condition. Use the generic netlink controller operations to
+ * find which ones are supported and which not.
+ *
+ * libwimaxll:wimaxll_open() takes care of checking versions.
+ *
+ * THE OPERATIONS:
+ *
+ * Each operation is defined in its on file (drivers/net/wimax/op-*.c)
+ * for clarity. The parts needed for an operation are:
+ *
+ * - a function pointer in `struct wimax_dev`: optional, as the
+ * operation might be implemented by the stack and not by the
+ * driver.
+ *
+ * All function pointers are named wimax_dev->op_*(), and drivers
+ * must implement them except where noted otherwise.
+ *
+ * - When exported to user space, a `struct nla_policy` to define the
+ * attributes of the generic netlink command and a `struct genl_ops`
+ * to define the operation.
+ *
+ * All the declarations for the operation codes (WIMAX_GNL_OP_<NAME>)
+ * and generic netlink attributes (WIMAX_GNL_<NAME>_*) are declared in
+ * include/linux/wimax.h; this file is intended to be cloned by user
+ * space to gain access to those declarations.
+ *
+ * A few caveats to remember:
+ *
+ * - Need to define attribute numbers starting in 1; otherwise it
+ * fails.
+ *
+ * - the `struct genl_family` requires a maximum attribute id; when
+ * defining the `struct nla_policy` for each message, it has to have
+ * an array size of WIMAX_GNL_ATTR_MAX+1.
+ *
+ * The op_*() function pointers will not be called if the wimax_dev is
+ * in a state <= %WIMAX_ST_UNINITIALIZED. The exception is:
+ *
+ * - op_reset: can be called at any time after wimax_dev_add() has
+ * been called.
+ *
+ * THE PIPE INTERFACE:
+ *
+ * This interface is kept intentionally simple. The driver can send
+ * and receive free-form messages to/from user space through a
+ * pipe. See drivers/net/wimax/op-msg.c for details.
+ *
+ * The kernel-to-user messages are sent with
+ * wimax_msg(). user-to-kernel messages are delivered via
+ * wimax_dev->op_msg_from_user().
+ *
+ * RFKILL:
+ *
+ * RFKILL support is built into the wimax_dev layer; the driver just
+ * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in
+ * the hardware or software RF kill switches. When the stack wants to
+ * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(),
+ * which the driver implements.
+ *
+ * User space can set the software RF Kill switch by calling
+ * wimax_rfkill().
+ *
+ * The code for now only supports devices that don't require polling;
+ * If the device needs to be polled, create a self-rearming delayed
+ * work struct for polling or look into adding polled support to the
+ * WiMAX stack.
+ *
+ * When initializing the hardware (_probe), after calling
+ * wimax_dev_add(), query the device for it's RF Kill switches status
+ * and feed it back to the WiMAX stack using
+ * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always
+ * report it as ON.
+ *
+ * NOTE: the wimax stack uses an inverted terminology to that of the
+ * RFKILL subsystem:
+ *
+ * - ON: radio is ON, RFKILL is DISABLED or OFF.
+ * - OFF: radio is OFF, RFKILL is ENABLED or ON.
+ *
+ * MISCELLANEOUS OPS:
+ *
+ * wimax_reset() can be used to reset the device to power on state; by
+ * default it issues a warm reset that maintains the same device
+ * node. If that is not possible, it falls back to a cold reset
+ * (device reconnect). The driver implements the backend to this
+ * through wimax_dev->op_reset().

+/**
+ * struct wimax_dev - Generic WiMAX device
+ *
+ * @net_dev: [fill] Pointer to the &struct net_device this WiMAX
+ * device implements.
+ *
+ * @op_msg_from_user: [fill] Driver-specific operation to
+ * handle a raw message from user space to the driver. The
+ * driver can send messages to user space using with
+ * wimax_msg_to_user().
+ *
+ * @op_rfkill_sw_toggle: [fill] Driver-specific operation to act on
+ * userspace (or any other agent) requesting the WiMAX device to
+ * change the RF Kill software switch (WIMAX_RF_ON or
+ * WIMAX_RF_OFF).
+ * If such hardware support is not present, it is assumed the
+ * radio cannot be switched off and it is always on (and the stack
+ * will error out when trying to switch it off). In such case,
+ * this function pointer can be left as NULL.
+ *
+ * @op_reset: [fill] Driver specific operation to reset the
+ * device.
+ * This operation should always attempt first a warm reset that
+ * does not disconnect the device from the bus and return 0.
+ * If that fails, it should resort to some sort of cold or bus
+ * reset (even if it implies a bus disconnection and device
+ * disappearance). In that case, -ENODEV should be returned to
+ * indicate the device is gone.
+ * This operation has to be synchronous, and return only when the
+ * reset is complete. In case of having had to resort to bus/cold
+ * reset implying a device disconnection, the call is allowed to
+ * return immediately.
+ * NOTE: wimax_dev->mutex is NOT locked when this op is being
+ * called; however, wimax_dev->mutex_reset IS locked to ensure
+ * serialization of calls to wimax_reset().
+ * See wimax_reset()'s documentation.
+ *
+ * @name: [fill] A way to identify this device. We need to register a
+ * name with many subsystems (rfkill, workqueue creation, etc).
+ * We can't use the network device name as that
+ * might change and in some instances we don't know it yet (until
+ * we don't call register_netdev()). So we generate an unique one
+ * using the driver name and device bus id, place it here and use
+ * it across the board. Recommended naming:
+ * DRIVERNAME-BUSNAME:BUSID (dev->bus->name, dev->bus_id).
+ *
+ * @id_table_node: [private] link to the list of wimax devices kept by
+ * id-table.c. Protected by it's own spinlock.
+ *
+ * @mutex: [private] Serializes all concurrent access and execution of
+ * operations.
+ *
+ * @mutex_reset: [private] Serializes reset operations. Needs to be a
+ * different mutex because as part of the reset operation, the
+ * driver has to call back into the stack to do things such as
+ * state change, that require wimax_dev->mutex.
+ *
+ * @state: [private] Current state of the WiMAX device.
+ *
+ * @rfkill: [private] integration into the RF-Kill infrastructure.
+ *
+ * @rf_sw: [private] State of the software radio switch (OFF/ON)
+ *
+ * @rf_hw: [private] State of the hardware radio switch (OFF/ON)
+ *
+ * @debugfs_dentry: [private] Used to hook up a debugfs entry. This
+ * shows up in the debugfs root as wimax\:DEVICENAME.
+ *
+ * Description:
+ * This structure defines a common interface to access all WiMAX
+ * devices from different vendors and provides a common API as well as
+ * a free-form device-specific messaging channel.
+ *
+ * Usage:
+ * 1. Embed a &struct wimax_dev at *the beginning* the network
+ * device structure so that netdev_priv() points to it.
+ *
+ * 2. memset() it to zero
+ *
+ * 3. Initialize with wimax_dev_init(). This will leave the WiMAX
+ * device in the %__WIMAX_ST_NULL state.
+ *
+ * 4. Fill all the fields marked with [fill]; once called
+ * wimax_dev_add(), those fields CANNOT be modified.
+ *
+ * 5. Call wimax_dev_add() *after* registering the network
+ * device. This will leave the WiMAX device in the %WIMAX_ST_DOWN
+ * state.
+ * Protect the driver's net_device->open() against succeeding if
+ * the wimax device state is lower than %WIMAX_ST_DOWN.
+ *
+ * 6. Select when the device is going to be turned on/initialized;
+ * for example, it could be initialized on 'ifconfig up' (when the
+ * netdev op 'open()' is called on the driver).
+ *
+ * When the device is initialized (at `ifconfig up` time, or right
+ * after calling wimax_dev_add() from _probe(), make sure the
+ * following steps are taken
+ *
+ * a. Move the device to %WIMAX_ST_UNINITIALIZED. This is needed so
+ * some API calls that shouldn't work until the device is ready
+ * can be blocked.
+ *
+ * b. Initialize the device. Make sure to turn the SW radio switch
+ * off and move the device to state %WIMAX_ST_RADIO_OFF when
+ * done. When just initialized, a device should be left in RADIO
+ * OFF state until user space devices to turn it on.
+ *
+ * c. Query the device for the state of the hardware rfkill switch
+ * and call wimax_rfkill_report_hw() and wimax_rfkill_report_sw()
+ * as needed. See below.
+ *
+ * wimax_dev_rm() undoes before unregistering the network device. Once
+ * wimax_dev_add() is called, the driver can get called on the
+ * wimax_dev->op_* function pointers
+ *
+ * CONCURRENCY:
+ *
+ * The stack provides a mutex for each device that will disallow API
+ * calls happening concurrently; thus, op calls into the driver
+ * through the wimax_dev->op*() function pointers will always be
+ * serialized and *never* concurrent.
+ *
+ * For locking, take wimax_dev->mutex is taken; (most) operations in
+ * the API have to check for wimax_dev_is_ready() to return 0 before
+ * continuing (this is done internally).
+ *
+ * REFERENCE COUNTING:
+ *
+ * The WiMAX device is reference counted by the associated network
+ * device. The only operation that can be used to reference the device
+ * is wimax_dev_get_by_genl_info(), and the reference it acquires has
+ * to be released with dev_put(wimax_dev->net_dev).
+ *
+ * RFKILL:
+ *
+ * At startup, both HW and SW radio switchess are assumed to be off.
+ *
+ * At initialization time [after calling wimax_dev_add()], have the
+ * driver query the device for the status of the software and hardware
+ * RF kill switches and call wimax_report_rfkill_hw() and
+ * wimax_rfkill_report_sw() to indicate their state. If any is
+ * missing, just call it to indicate it is ON (radio always on).
+ *
+ * Whenever the driver detects a change in the state of the RF kill
+ * switches, it should call wimax_report_rfkill_hw() or
+ * wimax_report_rfkill_sw() to report it to the stack.

+/* Organization of SPD aka "XFRM rules"
+ ------------------------------------
+
+ Basic objects:
+ - policy rule, struct xfrm_policy (=SPD entry)
+ - bundle of transformations, struct dst_entry == struct xfrm_dst (=SA bundle)
+ - instance of a transformer, struct xfrm_state (=SA)
+ - template to clone xfrm_state, struct xfrm_tmpl
+
+ SPD is plain linear list of xfrm_policy rules, ordered by priority.
+ (To be compatible with existing pfkeyv2 implementations,
+ many rules with priority of 0x7fffffff are allowed to exist and
+ such rules are ordered in an unpredictable way, thanks to bsd folks.)
+
+ Lookup is plain linear search until the first match with selector.
+
+ If "action" is "block", then we prohibit the flow, otherwise:
+ if "xfrms_nr" is zero, the flow passes untransformed. Otherwise,
+ policy entry has list of up to XFRM_MAX_DEPTH transformations,
+ described by templates xfrm_tmpl. Each template is resolved
+ to a complete xfrm_state (see below) and we pack bundle of transformations
+ to a dst_entry returned to requestor.
+
+ dst -. xfrm .-> xfrm_state #1
+ |---. child .-> dst -. xfrm .-> xfrm_state #2
+ |---. child .-> dst -. xfrm .-> xfrm_state #3
+ |---. child .-> NULL
+
+ Bundles are cached at xrfm_policy struct (field ->bundles).
+
+
+ Resolution of xrfm_tmpl
+ -----------------------
+ Template contains:
+ 1. ->mode Mode: transport or tunnel
+ 2. ->id.proto Protocol: AH/ESP/IPCOMP
+ 3. ->id.daddr Remote tunnel endpoint, ignored for transport mode.
+ Q: allow to resolve security gateway?
+ 4. ->id.spi If not zero, static SPI.
+ 5. ->saddr Local tunnel endpoint, ignored for transport mode.
+ 6. ->algos List of allowed algos. Plain bitmask now.
+ Q: ealgos, aalgos, calgos. What a mess...
+ 7. ->share Sharing mode.
+ Q: how to implement private sharing mode? To add struct sock* to
+ flow id?
+
+ Having this template we search through SAD searching for entries
+ with appropriate mode/proto/algo, permitted by selector.
+ If no appropriate entry found, it is requested from key manager.
+
+ PROBLEMS:
+ Q: How to find all the bundles referring to a physical path for
+ PMTU discovery? Seems, dst should contain list of all parents...
+ and enter to infinite locking hierarchy disaster.
+ No! It is easier, we will not search for them, let them find us.
+ We add genid to each dst plus pointer to genid of raw IP route,
+ pmtu disc will update pmtu on raw IP route and increase its genid.
+ dst_check() will see this for top level and trigger resyncing
+ metrics. Plus, it will be made via sk->sk_dst_cache. Solved.

+ * The OPL-3 mode is switched on by writing 0x01, to the offset 5
+ * of the right side.
+ *
+ * Another special register at the right side is at offset 4. It contains
+ * a bit mask defining which voices are used as 4 OP voices.
+ *
+ * The percussive mode is implemented in the left side only.
+ *
+ * With the above exceptions the both sides can be operated independently.
+ *
+ * A 4 OP voice can be created by setting the corresponding
+ * bit at offset 4 of the right side.
+ *
+ * For example setting the rightmost bit (0x01) changes the
+ * first voice on the right side to the 4 OP mode. The fourth
+ * voice is made inaccessible.
+ *
+ * If a voice is set to the 2 OP mode, it works like 2 OP modes
+ * of the original YM3812 (AdLib). In addition the voice can
+ * be connected the left, right or both stereo channels. It can
+ * even be left unconnected. This works with 4 OP voices also.
+ *
+ * The stereo connection bits are located in the FEEDBACK_CONNECTION
+ * register of the voice (0xC0-0xC8). In 4 OP voices these bits are
+ * in the second half of the voice.

+ * I915_L3_PARITY_UEVENT - Generated when the driver receives a parity mismatch
+ * event from the gpu l3 cache. Additional information supplied is ROW,
+ * BANK, SUBBANK, SLICE of the affected cacheline. Userspace should keep
+ * track of these events and if a specific cache-line seems to have a
+ * persistent error remap it with the l3 remapping tool supplied in
+ * intel-gpu-tools. The value supplied with the event is always 1.
+ *
+ * I915_ERROR_UEVENT - Generated upon error detection, currently only via
+ * hangcheck. The error detection event is a good indicator of when things
+ * began to go badly. The value supplied with the event is a 1 upon error
+ * detection, and a 0 upon reset completion, signifying no more error
+ * exists. NOTE: Disabling hangcheck or reset via module parameter will
+ * cause the related events to not be seen.
+ *
+ * I915_RESET_UEVENT - Event is generated just before an attempt to reset the
+ * the GPU. The value supplied with the event is always 1. NOTE: Disable
+ * reset via module parameter will cause this event to not be seen.

+ * For the CAN->CAN gwtype the indices of _two_ CAN interfaces are mandatory.
+ *
+ * CGW_FILTER (length 8 bytes):
+ * Sets a CAN receive filter for the gateway job specified by the
+ * struct can_filter described in include/linux/can.h
+ *
+ * CGW_MOD_(AND|OR|XOR|SET) (length 17 bytes):
+ * Specifies a modification that's done to a received CAN frame before it is
+ * send out to the destination interface.
+ *
+ * <struct can_frame> data used as operator
+ * <u8> affected CAN frame elements
+ *
+ * CGW_LIM_HOPS (length 1 byte):
+ * Limit the number of hops of this specific rule. Usually the received CAN
+ * frame can be processed as much as 'max_hops' times (which is given at module
+ * load time of the can-gw module). This value is used to reduce the number of
+ * possible hops for this gateway rule to a value smaller then max_hops.
+ *
+ * CGW_CS_XOR (length 4 bytes):
+ * Set a simple XOR checksum starting with an initial value into
+ * data[result-idx] using data[start-idx] .. data[end-idx]
+ *
+ * The XOR checksum is calculated like this:
+ *
+ * xor = init_xor_val
+ *
+ * for (i = from_idx .. to_idx)
+ * xor ^= can_frame.data[i]
+ *
+ * can_frame.data[ result_idx ] = xor
+ *
+ * CGW_CS_CRC8 (length 282 bytes):
+ * Set a CRC8 value into data[result-idx] using a given 256 byte CRC8 table,
+ * a given initial value and a defined input data[start-idx] .. data[end-idx].
+ * Finally the result value is XOR'ed with the final_xor_val.
+ *
+ * The CRC8 checksum is calculated like this:
+ *
+ * crc = init_crc_val
+ *
+ * for (i = from_idx .. to_idx)
+ * crc = crctab[ crc ^ can_frame.data[i] ]
+ *
+ * can_frame.data[ result_idx ] = crc ^ final_xor_val
+ *
+ * The calculated CRC may contain additional source data elements that can be
+ * defined in the handling of 'checksum profiles' e.g. shown in AUTOSAR specs
+ * like http://www.autosar.org/download/R4.0/AUTOSAR_SWS_E2ELibrary.pdf
+ * E.g. the profile_data[] may contain additional u8 values (called DATA_IDs)
+ * that are used depending on counter values inside the CAN frame data[].
+ * So far only three profiles have been implemented for illustration.
+ *
+ * Remark: In general the attribute data is a linear buffer.
+ * Beware of sending unpacked or aligned structs!

+/*******************************************************
+ * As of Linux 2.1.x, all Linux CD-ROM application programs will use this
+ * (and only this) include file. It is my hope to provide Linux with
+ * a uniform interface between software accessing CD-ROMs and the various
+ * device drivers that actually talk to the drives. There may still be
+ * 23 different kinds of strange CD-ROM drives, but at least there will
+ * now be one, and only one, Linux CD-ROM interface.
+ *
+ * Additionally, as of Linux 2.1.x, all Linux application programs
+ * should use the O_NONBLOCK option when opening a CD-ROM device
+ * for subsequent ioctl commands. This allows for neat system errors
+ * like "No medium found" or "Wrong medium type" upon attempting to
+ * mount or play an empty slot, mount an audio disc, or play a data disc.
+ * Generally, changing an application program to support O_NONBLOCK
+ * is as easy as the following:
+ * - drive = open("/dev/cdrom", O_RDONLY);
+ * + drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK);
+ * It is worth the small change.
+ *
+ * Patches for many common CD programs (provided by David A. van Leeuwen)
+ * can be found at: ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/

+ * DLM_LKF_NOQUEUE
+ *
+ * Do not queue the lock request on the wait queue if it cannot be granted

+ * either return -EAGAIN from the dlm_lock call or will return 0 from
+ * dlm_lock and -EAGAIN in the lock status block when the AST is executed.
+ *
+ * DLM_LKF_CANCEL
+ *
+ * Used to cancel a pending lock request or conversion. A converting lock is
+ * returned to its previously granted mode.
+ *
+ * DLM_LKF_CONVERT
+ *
+ * Indicates a lock conversion request. For conversions the name and namelen
+ * are ignored and the lock ID in the LKSB is used to identify the lock.
+ *
+ * DLM_LKF_VALBLK
+ *
+ * Requests DLM to return the current contents of the lock value block in the
+ * lock status block. When this flag is set in a lock conversion from PW or EX
+ * modes, DLM assigns the value specified in the lock status block to the lock
+ * value block of the lock resource. The LVB is a DLM_LVB_LEN size array
+ * containing application-specific information.
+ *
+ * DLM_LKF_QUECVT
+ *
+ * Force a conversion request to be queued, even if it is compatible with
+ * the granted modes of other locks on the same resource.
+ *
+ * DLM_LKF_IVVALBLK
+ *
+ * Invalidate the lock value block.
+ *
+ * DLM_LKF_CONVDEADLK
+ *
+ * Allows the dlm to resolve conversion deadlocks internally by demoting the
+ * granted mode of a converting lock to NL. The DLM_SBF_DEMOTED flag is
+ * returned for a conversion that's been effected by this.
+ *
+ * DLM_LKF_PERSISTENT
+ *
+ * Only relevant to locks originating in userspace. A persistent lock will not
+ * be removed if the process holding the lock exits.
+ *
+ * DLM_LKF_NODLCKWT
+ *
+ * Do not cancel the lock if it gets into conversion deadlock.
+ * Exclude this lock from being monitored due to DLM_LSFL_TIMEWARN.
+ *
+ * DLM_LKF_NODLCKBLK
+ *
+ * net yet implemented
+ *
+ * DLM_LKF_EXPEDITE
+ *
+ * Used only with new requests for NL mode locks. Tells the lock manager
+ * to grant the lock, ignoring other locks in convert and wait queues.
+ *
+ * DLM_LKF_NOQUEUEBAST
+ *
+ * Send blocking AST's before returning -EAGAIN to the caller. It is only
+ * used along with the NOQUEUE flag. Blocking AST's are not sent for failed
+ * NOQUEUE requests otherwise.
+ *
+ * DLM_LKF_HEADQUE
+ *
+ * Add a lock to the head of the convert or wait queue rather than the tail.
+ *
+ * DLM_LKF_NOORDER
+ *
+ * Disregard the standard grant order rules and grant a lock as soon as it
+ * is compatible with other granted locks.
+ *
+ * DLM_LKF_ORPHAN
+ *
+ * Acquire an orphan lock.
+ *
+ * DLM_LKF_ALTPR
+ *
+ * If the requested mode cannot be granted immediately, try to grant the lock
+ * in PR mode instead. If this alternate mode is granted instead of the
+ * requested mode, DLM_SBF_ALTMODE is returned in the lksb.
+ *
+ * DLM_LKF_ALTCW
+ *
+ * The same as ALTPR, but the alternate mode is CW.
+ *
+ * DLM_LKF_FORCEUNLOCK
+ *
+ * Unlock the lock even if it is converting or waiting or has sublocks.
+ * Only really for use by the userland device.c code.

+ * A traditional ioctl interface for the device mapper.

+ * 'active' table which is the one currently used by io passing
+ * through the device, and an 'inactive' one which is a table
+ * that is being prepared as a replacement for the 'active' one.
+ *
+ * DM_VERSION:
+ * Just get the version information for the ioctl interface.
+ *
+ * DM_REMOVE_ALL:
+ * Remove all dm devices, destroy all tables. Only really used
+ * for debug.
+ *
+ * DM_LIST_DEVICES:
+ * Get a list of all the dm device names.
+ *
+ * DM_DEV_CREATE:
+ * Create a new device, neither the 'active' or 'inactive' table
+ * slots will be filled. The device will be in suspended state
+ * after creation, however any io to the device will get errored
+ * since it will be out-of-bounds.
+ *
+ * DM_DEV_REMOVE:
+ * Remove a device, destroy any tables.
+ *
+ * DM_DEV_RENAME:
+ * Rename a device or set its uuid if none was previously supplied.
+ *
+ * DM_SUSPEND:
+ * This performs both suspend and resume, depending which flag is
+ * passed in.
+ * Suspend: This command will not return until all pending io to
+ * the device has completed. Further io will be deferred until
+ * the device is resumed.
+ * Resume: It is no longer an error to issue this command on an
+ * unsuspended device. If a table is present in the 'inactive'
+ * slot, it will be moved to the active slot, then the old table
+ * from the active slot will be _destroyed_. Finally the device
+ * is resumed.
+ *
+ * DM_DEV_STATUS:
+ * Retrieves the status for the table in the 'active' slot.
+ *
+ * DM_DEV_WAIT:
+ * Wait for a significant event to occur to the device. This
+ * could either be caused by an event triggered by one of the
+ * targets of the table in the 'active' slot, or a table change.
+ *
+ * DM_TABLE_LOAD:
+ * Load a table into the 'inactive' slot for the device. The
+ * device does _not_ need to be suspended prior to this command.
+ *
+ * DM_TABLE_CLEAR:
+ * Destroy any table in the 'inactive' slot (ie. abort).
+ *
+ * DM_TABLE_DEPS:
+ * Return a set of device dependencies for the 'active' table.
+ *
+ * DM_TABLE_STATUS:
+ * Return the targets status for the 'active' table.
+ *
+ * DM_TARGET_MSG:
+ * Pass a message string to the target at a specific offset of a device.
+ *
+ * DM_DEV_SET_GEOMETRY:
+ * Set the geometry of a device by passing in a string in this format:
+ *
+ * "cylinders heads sectors_per_track start_sector"
+ *
+ * Beware that CHS geometry is nearly obsolete and only provided
+ * for compatibility with dm devices that can be booted by a PC

+ * The device-mapper userspace log module consists of a kernel component and
+ * a user-space component. The kernel component implements the API defined
+ * in dm-dirty-log.h. Its purpose is simply to pass the parameters and
+ * return values of those API functions between kernel and user-space.
+ *
+ * Below are defined the 'request_types' - DM_ULOG_CTR, DM_ULOG_DTR, etc.
+ * These request types represent the different functions in the device-mapper
+ * dirty log API. Each of these is described in more detail below.
+ *
+ * The user-space program must listen for requests from the kernel (representing
+ * the various API functions) and process them.
+ *
+ * User-space begins by setting up the communication link (error checking
+ * removed for clarity):
+ * fd = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
+ * addr.nl_family = AF_NETLINK;
+ * addr.nl_groups = CN_IDX_DM;
+ * addr.nl_pid = 0;
+ * r = bind(fd, (struct sockaddr *) &addr, sizeof(addr));
+ * opt = addr.nl_groups;
+ * setsockopt(fd, SOL_NETLINK, NETLINK_ADD_MEMBERSHIP, &opt, sizeof(opt));
+ *
+ * User-space will then wait to receive requests form the kernel, which it
+ * will process as described below. The requests are received in the form,
+ * ((struct dm_ulog_request) + (additional data)). Depending on the request
+ * type, there may or may not be 'additional data'. In the descriptions below,
+ * you will see 'Payload-to-userspace' and 'Payload-to-kernel'. The
+ * 'Payload-to-userspace' is what the kernel sends in 'additional data' as
+ * necessary parameters to complete the request. The 'Payload-to-kernel' is
+ * the 'additional data' returned to the kernel that contains the necessary
+ * results of the request. The 'data_size' field in the dm_ulog_request

+ * In Linux, we implement the KVP functionality in two components:
+ * 1) The kernel component which is packaged as part of the hv_utils driver
+ * is responsible for communicating with the host and responsible for
+ * implementing the host/guest protocol. 2) A user level daemon that is
+ * responsible for data gathering.
+ *
+ * Host/Guest Protocol: The host iterates over an index and expects the guest
+ * to assign a key name to the index and also return the value corresponding to
+ * the key. The host will have atmost one KVP transaction outstanding at any
+ * given point in time. The host side iteration stops when the guest returns
+ * an error. Microsoft has specified the following mapping of key names to
+ * host specified index:
+ *
+ * Index Key Name
+ * 0 FullyQualifiedDomainName
+ * 1 IntegrationServicesVersion
+ * 2 NetworkAddressIPv4
+ * 3 NetworkAddressIPv6
+ * 4 OSBuildNumber
+ * 5 OSName
+ * 6 OSMajorVersion
+ * 7 OSMinorVersion
+ * 8 OSVersion
+ * 9 ProcessorArchitecture
+ *
+ * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ *
+ * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
+ * data gathering functionality in a user mode daemon. The user level daemon
+ * is also responsible for binding the key name to the index as well. The
+ * kernel and user-level daemon communicate using a connector channel.
+ *
+ * The user mode component first registers with the
+ * the kernel component. Subsequently, the kernel component requests, data
+ * for the specified keys. In response to this message the user mode component
+ * fills in the value corresponding to the specified key. We overload the
+ * sequence field in the cn_msg header to define our KVP message types.
+ *
+ *
+ * The kernel component simply acts as a conduit for communication between the
+ * Windows host and the user-level daemon. The kernel component passes up the
+ * index received from the Host to the user-level daemon. If the index is
+ * valid (supported), the corresponding key as well as its
+ * value (both are strings) is returned. If the index is invalid
+ * (not supported), a NULL key string is returned.

+ * The KVP opcodes are defined by the host and it was unfortunate
+ * that I chose to treat the registration operation as part of the
+ * KVP operations defined by the host.
+ * Here is the level of compatibility
+ * (between the user level daemon and the kernel KVP driver) that we
+ * will implement:
+ *
+ * An older daemon will always be supported on a newer driver.
+ * A given user level daemon will require a minimal version of the

+ * the standard rules for I2C transactions. Each transaction begins with a
+ * START. That is followed by the slave address, and a bit encoding read
+ * versus write. Then follow all the data bytes, possibly including a byte
+ * with SMBus PEC. The transfer terminates with a NAK, or when all those
+ * bytes have been transferred and ACKed. If this is the last message in a
+ * group, it is followed by a STOP. Otherwise it is followed by the next
+ * @i2c_msg transaction segment, beginning with a (repeated) START.
+ *
+ * Alternatively, when the adapter supports I2C_FUNC_PROTOCOL_MANGLING then
+ * passing certain @flags may have changed those standard protocol behaviors.
+ * Those flags are only for use with broken/nonconforming slaves, and with
+ * adapters which are known to support the specific mangling options they
+ * need (one or more of IGNORE_NAK, NO_RD_ACK, NOSTART, and REV_DIR_ADDR).

+ * entry available for all dev flags which can be queried and set. These flags

+ * other flags are always always preserved from the original net_device flags
+ * even if you try to set them via sysfs. Flags which are always preserved
+ * are kept under the flag grouping @IFF_VOLATILE. Flags which are volatile
+ * are annotated below as such.
+ *
+ * You should have a pretty good reason to be extending these flags.

+ * With that said, this driver provides a multi-user interface to the
+ * IPMI driver, and it allows multiple IPMI physical interfaces below
+ * the driver. The physical interfaces bind as a lower layer on the
+ * driver. They appear as interfaces to the application using this
+ * interface.
+ *
+ * Multi-user means that multiple applications may use the driver,
+ * send commands, receive responses, etc. The driver keeps track of
+ * commands the user sends and tracks the responses. The responses
+ * will go back to the application that send the command. If the
+ * response doesn't come back in time, the driver will return a
+ * timeout error response to the application. Asynchronous events
+ * from the BMC event queue will go to all users bound to the driver.
+ * The incoming event queue in the BMC will automatically be flushed
+ * if it becomes full and it is queried once a second to see if
+ * anything is in it. Incoming commands to the driver will get
+ * delivered as commands.

+* This group of IOCTLs deal with the record settings of the DSP
+*
+* The IXJCTL_REC_DEPTH command sets the internal buffer depth of the DSP.
+* Setting a lower depth reduces latency, but increases the demand of the
+* application to service the driver without frame loss. The DSP has 480
+* bytes of physical buffer memory for the record channel so the true
+* maximum limit is determined by how many frames will fit in the buffer.
+*
+* 1 uncompressed (480 byte) 16-bit linear frame.
+* 2 uncompressed (240 byte) 8-bit A-law/mu-law frames.
+* 15 TrueSpeech 8.5 frames.
+* 20 TrueSpeech 6.3,5.3,4.8 or 4.1 frames.
+*
+* The default in the driver is currently set to 2 frames.
+*
+* The IXJCTL_REC_VOLUME and IXJCTL_PLAY_VOLUME commands both use a Q8
+* number as a parameter, 0x100 scales the signal by 1.0, 0x200 scales the
+* signal by 2.0, 0x80 scales the signal by 0.5. No protection is given
+* against over-scaling, if the multiplication factor times the input
+* signal exceeds 16 bits, overflow distortion will occur. The default
+* setting is 0x100 (1.0).
+*
+* The IXJCTL_REC_LEVEL returns the average signal level (not r.m.s.) on
+* the most recently recorded frame as a 16 bit value.

+*
+* The IXJCTL_TONE_CADENCE ioctl defines tone sequences used for various
+* Call Progress Tones (CPT). This is accomplished by setting up an array of
+* IXJ_CADENCE_ELEMENT structures that sequentially define the states of
+* the tone sequence. The tone_on_time and tone_off time are in
+* 250 microsecond intervals. A pointer to this array is passed to the
+* driver as the ce element of an IXJ_CADENCE structure. The elements_used
+* must be set to the number of IXJ_CADENCE_ELEMENTS in the array. The
+* termination variable defines what to do at the end of a cadence, the
+* options are to play the cadence once and stop, to repeat the last
+* element of the cadence indefinitely, or to repeat the entire cadence
+* indefinitely. The ce variable is a pointer to the array of IXJ_TONE
+* structures. If the freq0 variable is non-zero, the tone table contents
+* for the tone_index are updated to the frequencies and gains defined. It
+* should be noted that DTMF tones cannot be reassigned, so if DTMF tone
+* table indexes are used in a cadence the frequency and gain variables will
+* be ignored.
+*
+* If the array elements contain frequency parameters the driver will
+* initialize the needed tone table elements and begin playing the tone,
+* there is no preset limit on the number of elements in the cadence. If
+* there is more than one frequency used in the cadence, sequential elements
+* of different frequencies MUST use different tone table indexes. Only one
+* cadence can be played at a time. It is possible to build complex
+* cadences with multiple frequencies using 2 tone table indexes by
+* alternating between them.

+/*
+ * Compatibility interface for userspace libc header coordination:
+ *
+ * Define compatibility macros that are used to control the inclusion or
+ * exclusion of UAPI structures and definitions in coordination with another
+ * userspace C library.
+ *
+ * This header is intended to solve the problem of UAPI definitions that
+ * conflict with userspace definitions. If a UAPI header has such conflicting
+ * definitions then the solution is as follows:
+ *
+ * * Synchronize the UAPI header and the libc headers so either one can be
+ * used and such that the ABI is preserved. If this is not possible then
+ * no simple compatibility interface exists (you need to write translating
+ * wrappers and rename things) and you can't use this interface.
+ *
+ * Then follow this process:
+ *
+ * (a) Include libc-compat.h in the UAPI header.
+ * e.g. #include <linux/libc-compat.h>
+ * This include must be as early as possible.
+ *
+ * (b) In libc-compat.h add enough code to detect that the comflicting
+ * userspace libc header has been included first.
+ *
+ * (c) If the userspace libc header has been included first define a set of
+ * guard macros of the form __UAPI_DEF_FOO and set their values to 1, else
+ * set their values to 0.
+ *
+ * (d) Back in the UAPI header with the conflicting definitions, guard the
+ * definitions with:
+ * #if __UAPI_DEF_FOO
+ * ...
+ * #endif
+ *
+ * This fixes the situation where the linux headers are included *after* the
+ * libc headers. To fix the problem with the inclusion in the other order the
+ * userspace libc headers must be fixed like this:
+ *
+ * * For all definitions that conflict with kernel definitions wrap those
+ * defines in the following:
+ * #if !__UAPI_DEF_FOO
+ * ...
+ * #endif
+ *
+ * This prevents the redefinition of a construct already defined by the kernel.

+ * the data format is fixed. Additionally, "2X8" means that one pixel is
+ * transferred in two 8-bit samples, "BE" or "LE" specify in which order those
+ * samples are transferred over the bus: "LE" means that the least significant
+ * bits are transferred first, "BE" means that the most significant bits are
+ * transferred first, and "PADHI" and "PADLO" define which bits - low or high,
+ * in the incomplete high byte, are filled with padding bits.
+ *
+ * The bus formats are grouped by type, bus_width, bits per component, samples
+ * per pixel and order of subsamples. Numerical values are sorted using generic
+ * numerical sort order (8 thus comes before 10).
+ *
+ * As their value can't change when a new bus format is inserted in the
+ * enumeration, the bus formats are explicitly given a numerical value. The next

+ * To retrieve the neighbour tables send RTM_GETNEIGHTBL with the

+ * size limits on systems with many interfaces. The first message
+ * in the sequence transports all not device specific data such as
+ * statistics, configuration, and the default parameter set.
+ * This message is followed by 0..n messages carrying device
+ * specific parameter sets.
+ * Although the ordering should be sufficient, NDTA_NAME can be

+ * by checking for NDTA_CONFIG. The device specific messages do
+ * not contain this TLV but have NDTPA_IFINDEX set to the
+ * corresponding interface index.
+ *
+ * To change neighbour table attributes, send RTM_SETNEIGHTBL
+ * with NDTA_NAME set. Changeable attribute include NDTA_THRESH[1-3],
+ * NDTA_GC_INTERVAL, and all TLVs in NDTA_PARMS unless marked

+ * (in `cmp' array). This is quick as it requires only two elementary
+ * number comparisons in worst case. Further, we take advantage of

+ * @NFC_EVENT_TARGETS_FOUND: event emitted when a new target is found
+ * (it sends %NFC_ATTR_DEVICE_INDEX)
+ * @NFC_EVENT_DEVICE_ADDED: event emitted when a new device is registred

+ * @NFC_EVENT_DEVICE_DEACTIVATED: event emitted when the adapter is deactivated
+ * from target mode.
+ * @NFC_CMD_LLC_GET_PARAMS: request LTO, RW, and MIUX parameters for a device
+ * @NFC_CMD_LLC_SET_PARAMS: set one or more of LTO, RW, and MIUX parameters for
+ * a device. LTO must be set before the link is up otherwise -EINPROGRESS
+ * is returned. RW and MIUX can be set at anytime and will be passed in
+ * subsequent CONNECT and CC messages.
+ * If one of the passed parameters is wrong none is set and -EINVAL is

+ * @NFC_CMD_FW_DOWNLOAD: Request to Load/flash firmware, or event to inform
+ * that some firmware was loaded
+ * @NFC_EVENT_SE_ADDED: Event emitted when a new secure element is discovered.
+ * This typically will be sent whenever a new NFC controller with either
+ * an embedded SE or an UICC one connected to it through SWP.
+ * @NFC_EVENT_SE_REMOVED: Event emitted when a secure element is removed from
+ * the system, as a consequence of e.g. an NFC controller being unplugged.
+ * @NFC_EVENT_SE_CONNECTIVITY: This event is emitted whenever a secure element
+ * is requesting connectivity access. For example a UICC SE may need to
+ * talk with a sleeping modem and will notify this need by sending this
+ * event. It is then up to userspace to decide if it will wake the modem
+ * up or not.
+ * @NFC_EVENT_SE_TRANSACTION: This event is sent when an application running on
+ * a specific SE notifies us about the end of a transaction. The parameter
+ * for this event is the application ID (AID).
+ * @NFC_CMD_GET_SE: Dump all discovered secure elements from an NFC controller.
+ * @NFC_CMD_SE_IO: Send/Receive APDUs to/from the selected secure element.

+ * - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
+ * to add rate and capability information to the station and at the same

+/**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ * these registrations are ignored until the interface type is
+ * changed again. This means that changing the interface type can
+ * lead to a situation that couldn't otherwise be produced, but
+ * any such registrations will be dormant in the sense that they
+ * will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

+ * DOC: Virtual interface / concurrency capabilities
+ *
+ * Some devices are able to operate with virtual MACs, they can have
+ * more than one virtual interface. The capability handling for this
+ * is a bit complex though, as there may be a number of restrictions
+ * on the types of concurrency that are supported.
+ *
+ * To start with, each device supports the interface types listed in
+ * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
+ * types there no concurrency is implied.
+ *
+ * Once concurrency is desired, more attributes must be observed:
+ * To start with, since some interface types are purely managed in
+ * software, like the AP-VLAN type in mac80211 for example, there's
+ * an additional list of these, they can be added at any time and
+ * are only restricted by some semantic restrictions (e.g. AP-VLAN
+ * cannot be added without a corresponding AP interface). This list
+ * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
+ *
+ * Further, the list of supported combinations is exported. This is
+ * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
+ * it exports a list of "groups", and at any point in time the
+ * interfaces that are currently active must fall into any one of
+ * the advertised groups. Within each group, there are restrictions
+ * on the number of interfaces of different types that are supported
+ * and also the number of different channels, along with potentially
+ * some other restrictions. See &enum nl80211_if_combination_attrs.
+ *
+ * All together, these attributes define the concurrency of virtual
+ * interfaces that a given device supports.

+ * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
+ * after being queried by the kernel. CRDA replies by sending a regulatory
+ * domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
+ * current alpha2 if it found a match. It also provides

+ *
+ * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
+ * interface identified by %NL80211_ATTR_IFINDEX
+ *
+ * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
+ * interface is identified with %NL80211_ATTR_IFINDEX and the management
+ * frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
+ * added to the end of the specified management frame is specified with
+ * %NL80211_ATTR_IE. If the command succeeds, the requested data will be
+ * added to all specified management frames generated by
+ * kernel/firmware/driver.
+ * Note: This command has been removed and it is only reserved at this
+ * point to avoid re-using existing command number. The functionality this
+ * command was planned for has been provided with cleaner design with the

+ * NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
+ * NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
+ *
+ * @NL80211_CMD_GET_SCAN: get scan results
+ * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
+ * %NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
+ * probe requests at CCK rate or not.
+ * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
+ * NL80211_CMD_GET_SCAN and on the "scan" multicast group)
+ * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
+ * partial scan results may be available
+ *
+ * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
+ * intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
+ * Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
+ * are passed, they are used in the probe requests. For
+ * broadcast, a broadcast SSID must be passed (ie. an empty
+ * string). If no SSID is passed, no probe requests are sent and
+ * a passive scan is performed. %NL80211_ATTR_SCAN_FREQUENCIES,
+ * if passed, define which channels should be scanned; if not
+ * passed, all channels allowed for the current regulatory domain
+ * are used. Extra IEs can also be passed from the userspace by
+ * using the %NL80211_ATTR_IE attribute. The first cycle of the
+ * scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
+ * is supplied.
+ * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
+ * scheduled scan is not running. The caller may assume that as soon
+ * as the call returns, it is safe to start a new scheduled scan again.
+ * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
+ * results available.
+ * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
+ * stopped. The driver may issue this event at any time during a
+ * scheduled scan. One reason for stopping the scan is if the hardware
+ * does not support starting an association or a normal scan while running
+ * a scheduled scan. This event is also sent when the
+ * %NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
+ * is brought down while a scheduled scan was running.
+ *
+ * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
+ * or noise level
+ * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
+ * NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
+ *
+ * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
+ * (for the BSSID) and %NL80211_ATTR_PMKID.
+ * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
+ * (for the BSSID) and %NL80211_ATTR_PMKID.
+ * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
+ *
+ * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
+ * has been changed and provides details of the request information
+ * that caused the change such as who initiated the regulatory request
+ * (%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
+ * (%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
+ * the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
+ * %NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
+ * set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
+ * %NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
+ * to (%NL80211_ATTR_REG_ALPHA2).
+ * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
+ * has been found while world roaming thus enabling active scan or
+ * any mode of operation that initiates TX (beacons) on a channel
+ * where we would not have been able to do either before. As an example
+ * if you are world roaming (regulatory domain set to world or if your
+ * driver is using a custom world roaming regulatory domain) and while
+ * doing a passive scan on the 5 GHz band you find an AP there (if not
+ * on a DFS channel) you will now be able to actively scan for that AP
+ * or use AP mode on your card on that same channel. Note that this will
+ * never be used for channels 1-11 on the 2 GHz band as they are always
+ * enabled world wide. This beacon hint is only sent if your device had
+ * either disabled active scanning or beaconing on a channel. We send to
+ * userspace the wiphy on which we removed a restriction from
+ * (%NL80211_ATTR_WIPHY) and the channel on which this occurred
+ * before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
+ * the beacon hint was processed.
+ *
+ * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
+ * This command is used both as a command (request to authenticate) and
+ * as an event on the "mlme" multicast group indicating completion of the
+ * authentication process.
+ * When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
+ * interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
+ * BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
+ * the SSID (mainly for association, but is included in authentication
+ * request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
+ * to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
+ * is used to specify the authentication type. %NL80211_ATTR_IE is used to
+ * define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
+ * to be added to the frame.
+ * When used as an event, this reports reception of an Authentication
+ * frame in station and IBSS modes when the local MLME processed the
+ * frame, i.e., it was for the local STA and was received in correct
+ * state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
+ * MLME SAP interface (kernel providing MLME, userspace SME). The
+ * included %NL80211_ATTR_FRAME attribute contains the management frame
+ * (including both the header and frame body, but not FCS). This event is
+ * also used to indicate if the authentication attempt timed out. In that
+ * case the %NL80211_ATTR_FRAME attribute is replaced with a
+ * %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
+ * pending authentication timed out).
+ * @NL80211_CMD_ASSOCIATE: association request and notification; like
+ * NL80211_CMD_AUTHENTICATE but for Association and Reassociation
+ * (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
+ * MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
+ * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
+ * NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
+ * MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
+ * primitives).
+ * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
+ * NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
+ * MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
+ *
+ * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
+ * MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
+ * event includes %NL80211_ATTR_MAC to describe the source MAC address of
+ * the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
+ * type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
+ * %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
+ * event matches with MLME-MICHAELMICFAILURE.indication() primitive
+ *
+ * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
+ * FREQ attribute (for the initial frequency if no peer can be found)
+ * and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
+ * should be fixed rather than automatically determined. Can only be
+ * executed on a network interface that is UP, and fixed BSSID/FREQ
+ * may be rejected. Another optional parameter is the beacon interval,
+ * given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
+ * given defaults to 100 TU (102.4ms).
+ * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
+ * determined by the network interface.
+ *
+ * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
+ * to identify the device, and the TESTDATA blob attribute to pass through
+ * to the driver.
+ *
+ * @NL80211_CMD_CONNECT: connection request and notification; this command
+ * requests to connect to a specified network but without separating
+ * auth and assoc steps. For this, you need to specify the SSID in a
+ * %NL80211_ATTR_SSID attribute, and can optionally specify the association
+ * IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
+ * %NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
+ * %NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
+ * %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and
+ * %NL80211_ATTR_WIPHY_FREQ_HINT.
+ * If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
+ * restrictions on BSS selection, i.e., they effectively prevent roaming
+ * within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
+ * can be included to provide a recommendation of the initial BSS while
+ * allowing the driver to roam to other BSSes within the ESS and also to
+ * ignore this recommendation if the indicated BSS is not ideal. Only one
+ * set of BSSID,frequency parameters is used (i.e., either the enforcing
+ * %NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
+ * %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
+ * Background scan period can optionally be
+ * specified in %NL80211_ATTR_BG_SCAN_PERIOD,
+ * if not specified default background scan configuration
+ * in driver is used and if period value is 0, bg scan will be disabled.
+ * This attribute is ignored if driver does not support roam scan.
+ * It is also sent as an event, with the BSSID and response IEs when the
+ * connection is established or failed to be established. This can be
+ * determined by the STATUS_CODE attribute.
+ * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
+ * sent as an event when the card/driver roamed by itself.
+ * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
+ * userspace that a connection was dropped by the AP or due to other
+ * reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
+ * %NL80211_ATTR_REASON_CODE attributes are used.
+ *
+ * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
+ * associated with this wiphy must be down and will follow.
+ *
+ * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
+ * channel for the specified amount of time. This can be used to do
+ * off-channel operations like transmit a Public Action frame and wait for
+ * a response while being associated to an AP on another channel.
+ * %NL80211_ATTR_IFINDEX is used to specify which interface (and thus
+ * radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
+ * frequency for the operation.
+ * %NL80211_ATTR_DURATION is used to specify the duration in milliseconds
+ * to remain on the channel. This command is also used as an event to
+ * notify when the requested duration starts (it may take a while for the
+ * driver to schedule this time due to other concurrent needs for the
+ * radio).
+ * When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
+ * that will be included with any events pertaining to this request;
+ * the cookie is also used to cancel the request.
+ * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
+ * pending remain-on-channel duration if the desired operation has been
+ * completed prior to expiration of the originally requested duration.
+ * %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
+ * radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
+ * uniquely identify the request.
+ * This command is also used as an event to notify when a requested
+ * remain-on-channel duration has expired.
+ *
+ * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
+ * rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
+ * and @NL80211_ATTR_TX_RATES the set of allowed rates.
+ *
+ * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
+ * (via @NL80211_CMD_FRAME) for processing in userspace. This command
+ * requires an interface index, a frame type attribute (optional for
+ * backward compatibility reasons, if not given assumes action frames)
+ * and a match attribute containing the first few bytes of the frame
+ * that should match, e.g. a single byte for only a category match or
+ * four bytes for vendor frames including the OUI. The registration
+ * cannot be dropped, but is removed automatically when the netlink
+ * socket is closed. Multiple registrations can be made.
+ * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
+ * backward compatibility
+ * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
+ * command is used both as a request to transmit a management frame and
+ * as an event indicating reception of a frame that was not processed in
+ * kernel code, but is for us (i.e., which may need to be processed in a
+ * user space application). %NL80211_ATTR_FRAME is used to specify the
+ * frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
+ * to indicate on which channel the frame is to be transmitted or was
+ * received. If this channel is not the current channel (remain-on-channel
+ * or the operational channel) the device will switch to the given channel
+ * and transmit the frame, optionally waiting for a response for the time
+ * specified using %NL80211_ATTR_DURATION. When called, this operation
+ * returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
+ * TX status event pertaining to the TX request.
+ * %NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
+ * management frames at CCK rate or not in 2GHz band.
+ * %NL80211_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
+ * counters which will be updated to the current value. This attribute
+ * is used during CSA period.
+ * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
+ * command may be used with the corresponding cookie to cancel the wait
+ * time if it is known that it is no longer necessary.
+ * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
+ * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
+ * transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
+ * the TX command and %NL80211_ATTR_FRAME includes the contents of the
+ * frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
+ * the frame.
+ * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
+ * backward compatibility.
+ *
+ * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
+ * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
+ *
+ * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
+ * is used to configure connection quality monitoring notification trigger
+ * levels.
+ * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
+ * command is used as an event to indicate the that a trigger level was
+ * reached.
+ * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
+ * and the attributes determining channel width) the given interface
+ * (identifed by %NL80211_ATTR_IFINDEX) shall operate on.
+ * In case multiple channels are supported by the device, the mechanism
+ * with which it switches channels is implementation-defined.
+ * When a monitor interface is given, it can only switch channel while
+ * no other interfaces are operating to avoid disturbing the operation
+ * of any other interfaces, and other interfaces will again take
+ * precedence when they are used.
+ *
+ * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
+ *
+ * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
+ * mesh config parameters may be given.
+ * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
+ * network is determined by the network interface.
+ *
+ * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
+ * notification. This event is used to indicate that an unprotected
+ * deauthentication frame was dropped when MFP is in use.
+ * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
+ * notification. This event is used to indicate that an unprotected
+ * disassociation frame was dropped when MFP is in use.
+ *
+ * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
+ * beacon or probe response from a compatible mesh peer. This is only
+ * sent while no station information (sta_info) exists for the new peer
+ * candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
+ * @NL80211_MESH_SETUP_USERSPACE_AMPE, or
+ * @NL80211_MESH_SETUP_USERSPACE_MPM is set. On reception of this
+ * notification, userspace may decide to create a new station
+ * (@NL80211_CMD_NEW_STATION). To stop this notification from
+ * reoccurring, the userspace authentication daemon may want to create the
+ * new station with the AUTHENTICATED flag unset and maybe change it later
+ * depending on the authentication result.
+ *
+ * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
+ * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
+ * Since wireless is more complex than wired ethernet, it supports
+ * various triggers. These triggers can be configured through this
+ * command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
+ * more background information, see
+ * http://wireless.kernel.org/en/users/Documentation/WoWLAN.
+ * The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
+ * from the driver reporting the wakeup reason. In this case, the
+ * @NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
+ * for the wakeup, if it was caused by wireless. If it is not present
+ * in the wakeup notification, the wireless device didn't cause the
+ * wakeup but reports that it was woken up.
+ *
+ * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
+ * the necessary information for supporting GTK rekey offload. This
+ * feature is typically used during WoWLAN. The configuration data
+ * is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
+ * contains the data in sub-attributes). After rekeying happened,
+ * this command may also be sent by the driver as an MLME event to
+ * inform userspace of the new replay counter.
+ *
+ * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
+ * of PMKSA caching dandidates.
+ *
+ * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
+ * In addition, this can be used as an event to request userspace to take
+ * actions on TDLS links (set up a new link or tear down an existing one).
+ * In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
+ * operation, %NL80211_ATTR_MAC contains the peer MAC address, and
+ * %NL80211_ATTR_REASON_CODE the reason code to be used (only with
+ * %NL80211_TDLS_TEARDOWN).
+ * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
+ * %NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
+ * sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
+ * 802.11 management frames, while TDLS action codes (802.11-2012
+ * 8.5.13.1) will be encapsulated and sent as data frames. The currently
+ * supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
+ * and the currently supported TDLS actions codes are given in
+ * &enum ieee80211_tdls_actioncode.
+ *
+ * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
+ * (or GO) interface (i.e. hostapd) to ask for unexpected frames to
+ * implement sending deauth to stations that send unexpected class 3
+ * frames. Also used as the event sent by the kernel when such a frame
+ * is received.
+ * For the event, the %NL80211_ATTR_MAC attribute carries the TA and
+ * other attributes like the interface index are present.
+ * If used as the command it must have an interface index and you can
+ * only unsubscribe from the event by closing the socket. Subscription
+ * is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
+ *
+ * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
+ * associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
+ * and wasn't already in a 4-addr VLAN. The event will be sent similarly
+ * to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
+ *
+ * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
+ * by sending a null data frame to it and reporting when the frame is
+ * acknowleged. This is used to allow timing out inactive clients. Uses
+ * %NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
+ * direct reply with an %NL80211_ATTR_COOKIE that is later used to match
+ * up the event with the request. The event includes the same data and
+ * has %NL80211_ATTR_ACK set if the frame was ACKed.
+ *
+ * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
+ * other BSSes when any interfaces are in AP mode. This helps implement
+ * OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
+ * messages. Note that per PHY only one application may register.
+ *
+ * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
+ * No Acknowledgement Policy should be applied.
+ *
+ * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
+ * independently of the userspace SME, send this event indicating
+ * %NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
+ * attributes determining channel width. This indication may also be
+ * sent when a remotely-initiated switch (e.g., when a STA receives a CSA
+ * from the remote AP) is completed;
+ *
+ * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
+ * has been started on an interface, regardless of the initiator
+ * (ie. whether it was requested from a remote device or
+ * initiated on our own). It indicates that
+ * %NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
+ * after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's. The userspace may
+ * decide to react to this indication by requesting other
+ * interfaces to change channel as well.
+ *
+ * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
+ * its %NL80211_ATTR_WDEV identifier. It must have been created with
+ * %NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
+ * P2P Device can be used for P2P operations, e.g. remain-on-channel and
+ * public action frame TX.
+ * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
+ * its %NL80211_ATTR_WDEV identifier.
+ *
+ * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
+ * notify userspace that AP has rejected the connection request from a
+ * station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
+ * is used for this.
+ *
+ * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
+ * for IBSS or MESH vif.
+ *
+ * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
+ * This is to be used with the drivers advertising the support of MAC
+ * address based access control. List of MAC addresses is passed in
+ * %NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
+ * %NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
+ * is not already done. The new list will replace any existing list. Driver
+ * will clear its ACL when the list of MAC addresses passed is empty. This
+ * command is used in AP/P2P GO mode. Driver has to make sure to clear its
+ * ACL list during %NL80211_CMD_STOP_AP.
+ *
+ * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
+ * a radar is detected or the channel availability scan (CAC) has finished
+ * or was aborted, or a radar was detected, usermode will be notified with
+ * this event. This command is also used to notify userspace about radars
+ * while operating on this channel.
+ * %NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
+ * event.
+ *
+ * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
+ * i.e. features for the nl80211 protocol rather than device features.
+ * Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
+ *
+ * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
+ * Information Element to the WLAN driver
+ *
+ * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
+ * to the supplicant. This will carry the target AP's MAC address along
+ * with the relevant Information Elements. This event is used to report
+ * received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
+ *
+ * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
+ * a critical protocol that needs more reliability in the connection to
+ * complete.
+ *
+ * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
+ * return back to normal.
+ *
+ * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
+ * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
+ *
+ * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
+ * the new channel information (Channel Switch Announcement - CSA)
+ * in the beacon for some time (as defined in the
+ * %NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
+ * new channel. Userspace provides the new channel information (using
+ * %NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
+ * width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
+ * other station that transmission must be blocked until the channel
+ * switch is complete.
+ *
+ * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
+ * by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
+ * %NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
+ * %NL80211_ATTR_VENDOR_DATA.
+ * For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
+ * used in the wiphy data as a nested attribute containing descriptions
+ * (&struct nl80211_vendor_cmd_info) of the supported vendor commands.
+ * This may also be sent as an event with the same attributes.
+ *
+ * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
+ * The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
+ * that attribute is not included, QoS mapping is disabled. Since this
+ * QoS mapping is relevant for IP packets, it is only valid during an
+ * association. This is cleared on disassociation and AP restart.
+ *
+ * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
+ * %NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
+ * and %NL80211_ATTR_ADMITTED_TIME parameters.
+ * Note that the action frame handshake with the AP shall be handled by
+ * userspace via the normal management RX/TX framework, this only sets
+ * up the TX TS in the driver/device.
+ * If the admitted time attribute is not added then the request just checks
+ * if a subsequent setup could be successful, the intent is to use this to
+ * avoid setting up a session with the AP when local restrictions would
+ * make that impossible. However, the subsequent "real" setup may still
+ * fail even if the check was successful.
+ * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
+ * and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
+ * before removing a station entry entirely, or before disassociating
+ * or similar, cleanup will happen in the driver/device in this case.
+ *
+ * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
+ * destination %NL80211_ATTR_MAC on the interface identified by
+ * %NL80211_ATTR_IFINDEX.
+ *
+ * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
+ * bandwidth of a channel must be given.
+ * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
+ * network is determined by the network interface.
+ *
+ * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
+ * identified by the %NL80211_ATTR_MAC parameter. A target channel is
+ * provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
+ * channel width/type. The target operating class is given via
+ * %NL80211_ATTR_OPER_CLASS.
+ * The driver is responsible for continually initiating channel-switching
+ * operations and returning to the base channel for communication with the
+ * AP.
+ * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
+ * peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
+ * when this command completes.
+ *
+ * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
+ * as an event to indicate changes for devices with wiphy-specific regdom
+ * management.
+ *
+ * @NL80211_CMD_MAX: highest used command number
+ * @__NL80211_CMD_AFTER_LAST: internal use

+ * @NL80211_ATTR_MESH_CONFIG: Mesh configuration parameters, a nested attribute
+ * containing attributes from &enum nl80211_meshconf_params.
+ * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
+ * allows auth frames in a mesh to be passed to userspace for processing via
+ * the @NL80211_MESH_SETUP_USERSPACE_AUTH flag.
+ * @NL80211_ATTR_STA_PLINK_STATE: The state of a mesh peer link as defined in
+ * &enum nl80211_plink_state. Used when userspace is driving the peer link

+ * able to ignore them by itself.
+ * Thus, the implementation is somewhat hardware-dependent, but
+ * this is only an optimization and the userspace application
+ * needs to handle all the non-filtered results anyway.
+ * If the match attributes don't make sense when combined with
+ * the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID

+ * driver (or firmware) replies to Probe Request frames.
+ * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
+ * Response frames. This is used with %NL80211_CMD_NEW_BEACON and

+ *
+ * @NL80211_ATTR_TX_NO_CCK_RATE: Indicates whether to use CCK rate or not
+ * for management frames transmission. In order to avoid p2p probe/action
+ * frames are being transmitted at CCK rate in 2GHz band, the user space

+ * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
+ * the driver to not wait for an acknowledgement. Note that due to this,
+ * it will also not give a status callback nor return a cookie. This is
+ * mostly useful for probe responses to save airtime.

+ * up to 16 TIDs.
+ *
+ * @NL80211_ATTR_INACTIVITY_TIMEOUT: timeout value in seconds, this can be
+ * used by the drivers which has MLME in firmware and does not have support

+ * DOC: TCP connection wakeup
+ *
+ * Some devices can establish a TCP connection in order to be woken up by a
+ * packet coming in from outside their network segment, or behind NAT. If
+ * configured, the device will establish a TCP connection to the given
+ * service, and periodically send data to that service. The first data
+ * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
+ * The data packets can optionally include a (little endian) sequence
+ * number (in the TCP payload!) that is generated by the device, and, also
+ * optionally, a token from a list of tokens. This serves as a keep-alive
+ * with the service, and for NATed connections, etc.
+ *
+ * During this keep-alive period, the server doesn't send any data to the
+ * client. When receiving data, it is compared against the wakeup pattern
+ * (and mask) and if it matches, the host is woken up. Similarly, if the
+ * connection breaks or cannot be established to start with, the host is
+ * also woken up.
+ *
+ * Developer's note: ARP offload is required for this, otherwise TCP
+ * response packets might not go through correctly.

+/* pg.h (c) 1998 Grant R. Guenther <grant@torque.net>
+ Under the terms of the GNU General Public License
+
+
+ pg.h defines the user interface to the generic ATAPI packet
+ command driver for parallel port ATAPI devices (pg). The
+ driver is loosely modelled after the generic SCSI driver, sg,
+ although the actual interface is different.
+
+ The pg driver provides a simple character device interface for
+ sending ATAPI commands to a device. With the exception of the
+ ATAPI reset operation, all operations are performed by a pair
+ of read and write operations to the appropriate /dev/pgN device.
+ A write operation delivers a command and any outbound data in
+ a single buffer. Normally, the write will succeed unless the
+ device is offline or malfunctioning, or there is already another
+ command pending. If the write succeeds, it should be followed
+ immediately by a read operation, to obtain any returned data and
+ status information. A read will fail if there is no operation
+ in progress.
+
+ As a special case, the device can be reset with a write operation,
+ and in this case, no following read is expected, or permitted.
+
+ There are no ioctl() operations. Any single operation
+ may transfer at most PG_MAX_DATA bytes. Note that the driver must
+ copy the data through an internal buffer. In keeping with all
+ current ATAPI devices, command packets are assumed to be exactly
+ 12 bytes in length.
+
+ To permit future changes to this interface, the headers in the
+ read and write buffers contain a single character "magic" flag.
+ Currently this flag must be the character "P".

+ * @tx_buf: Holds pointer to userspace buffer with transmit data, or null.
+ * If no data is provided, zeroes are shifted out.
+ * @rx_buf: Holds pointer to userspace buffer for receive data, or null.
+ * @len: Length of tx and rx buffers, in bytes.
+ * @speed_hz: Temporary override of the device's bitrate.
+ * @bits_per_word: Temporary override of the device's wordsize.
+ * @delay_usecs: If nonzero, how long to delay after the last bit transfer
+ * before optionally deselecting the device before the next transfer.
+ * @cs_change: True to deselect device before starting the next transfer.
+ *
+ * This structure is mapped directly to the kernel spi_transfer structure;
+ * the fields have the same meanings, except of course that the pointers
+ * are in a different address space (and may be of different sizes in some
+ * cases, such as 32-bit i386 userspace over a 64-bit x86_64 kernel).
+ * Zero-initialize the structure, including currently unused fields, to
+ * accommodate potential future updates.
+ *
+ * SPI_IOC_MESSAGE gives userspace the equivalent of kernel spi_sync().
+ * Pass it an array of related transfers, they'll execute together.
+ * Each transfer may be half duplex (either direction) or full duplex.
+ *
+ * struct spi_ioc_transfer mesg[4];
+ * ...
+ * status = ioctl(fd, SPI_IOC_MESSAGE(4), mesg);
+ *
+ * So for example one transfer might send a nine bit command (right aligned
+ * in a 16-bit word), the next could read a block of 8-bit data before
+ * terminating that command by temporarily deselecting the chip; the next
+ * could send a different nine bit command (re-selecting the chip), and the
+ * last transfer might write some register values.

+ * The mmaped area is divided into three parts:
+ * 1) The mailbox (struct tcmu_mailbox, below)
+ * 2) The command ring
+ * 3) Everything beyond the command ring (data)
+ *
+ * The mailbox tells userspace the offset of the command ring from the
+ * start of the shared memory region, and how big the command ring is.
+ *
+ * The kernel passes SCSI commands to userspace by putting a struct
+ * tcmu_cmd_entry in the ring, updating mailbox->cmd_head, and poking
+ * userspace via uio's interrupt mechanism.
+ *
+ * tcmu_cmd_entry contains a header. If the header type is PAD,
+ * userspace should skip hdr->length bytes (mod cmdr_size) to find the
+ * next cmd_entry.
+ *
+ * Otherwise, the entry will contain offsets into the mmaped area that
+ * contain the cdb and data buffers -- the latter accessible via the
+ * iov array. iov addresses are also offsets into the shared area.
+ *
+ * When userspace is completed handling the command, set
+ * entry->rsp.scsi_status, fill in rsp.sense_buffer if appropriate,
+ * and also set mailbox->cmd_tail equal to the old cmd_tail plus
+ * hdr->length, mod cmdr_size. If cmd_tail doesn't equal cmd_head, it

+ * This file holds USB constants and structures that are needed for
+ * USB device APIs. These are used by the USB device model, which is
+ * defined in chapter 9 of the USB 2.0 specification and in the
+ * Wireless USB 1.0 (spread around). Linux has several APIs in C that
+ * need these:
+ *
+ * - the master/host side Linux-USB kernel driver API;
+ * - the "usbfs" user space API; and
+ * - the Linux "gadget" slave/device/peripheral side driver API.
+ *
+ * USB 2.0 adds an additional "On The Go" (OTG) mode, which lets systems
+ * act either as a USB master/host or as a USB slave/device. That means
+ * the master and slave side APIs benefit from working well together.
+ *
+ * There's also "Wireless USB", using low power short range radios for
+ * peripheral interconnection but otherwise building on the USB framework.
+ *
+ * Note all descriptors are declared '__attribute__((packed))' so that:
+ *
+ * [a] they never get padded, either internally (USB spec writers
+ * probably handled that) or externally;
+ *
+ * [b] so that accessing bigger-than-a-bytes fields will never
+ * generate bus errors on any platform, even when the location of
+ * its descriptor inside a bundle isn't "naturally aligned", and
+ *
+ * [c] for consistency, removing all doubt even when it appears to
+ * someone that the two other points are non-issues for that
+ * particular descriptor type.

+ * from userspace (ie. simulate hardware triggering).
+ *
+ * Setting of an event triggering mechanism to userspace for ACTION_TRIGGER

+/**
+ * enum wimax_st - The different states of a WiMAX device
+ * @__WIMAX_ST_NULL: The device structure has been allocated and zeroed,
+ * but still wimax_dev_add() hasn't been called. There is no state.
+ *
+ * @WIMAX_ST_DOWN: The device has been registered with the WiMAX and
+ * networking stacks, but it is not initialized (normally that is
+ * done with 'ifconfig DEV up' [or equivalent], which can upload
+ * firmware and enable communications with the device).
+ * In this state, the device is powered down and using as less
+ * power as possible.
+ * This state is the default after a call to wimax_dev_add(). It
+ * is ok to have drivers move directly to %WIMAX_ST_UNINITIALIZED
+ * or %WIMAX_ST_RADIO_OFF in _probe() after the call to
+ * wimax_dev_add().
+ * It is recommended that the driver leaves this state when
+ * calling 'ifconfig DEV up' and enters it back on 'ifconfig DEV
+ * down'.
+ *
+ * @__WIMAX_ST_QUIESCING: The device is being torn down, so no API
+ * operations are allowed to proceed except the ones needed to
+ * complete the device clean up process.
+ *
+ * @WIMAX_ST_UNINITIALIZED: [optional] Communication with the device
+ * is setup, but the device still requires some configuration
+ * before being operational.
+ * Some WiMAX API calls might work.
+ *
+ * @WIMAX_ST_RADIO_OFF: The device is fully up; radio is off (wether
+ * by hardware or software switches).
+ * It is recommended to always leave the device in this state
+ * after initialization.
+ *
+ * @WIMAX_ST_READY: The device is fully up and radio is on.
+ *
+ * @WIMAX_ST_SCANNING: [optional] The device has been instructed to
+ * scan. In this state, the device cannot be actively connected to
+ * a network.
+ *
+ * @WIMAX_ST_CONNECTING: The device is connecting to a network. This
+ * state exists because in some devices, the connect process can
+ * include a number of negotiations between user space, kernel
+ * space and the device. User space needs to know what the device
+ * is doing. If the connect sequence in a device is atomic and
+ * fast, the device can transition directly to CONNECTED
+ *
+ * @WIMAX_ST_CONNECTED: The device is connected to a network.
+ *
+ * @__WIMAX_ST_INVALID: This is an invalid state used to mark the
+ * maximum numeric value of states.
+ *
+ * Description:
+ *
+ * Transitions from one state to another one are atomic and can only
+ * be caused in kernel space with wimax_state_change(). To read the
+ * state, use wimax_state_get().
+ *
+ * States starting with __ are internal and shall not be used or
+ * referred to by drivers or userspace. They look ugly, but that's the
+ * point -- if any use is made non-internal to the stack, it is easier
+ * to catch on review.
+ *
+ * All API operations [with well defined exceptions] will take the
+ * device mutex before starting and then check the state. If the state
+ * is %__WIMAX_ST_NULL, %WIMAX_ST_DOWN, %WIMAX_ST_UNINITIALIZED or
+ * %__WIMAX_ST_QUIESCING, it will drop the lock and quit with
+ * -%EINVAL, -%ENOMEDIUM, -%ENOTCONN or -%ESHUTDOWN.
+ *
+ * The order of the definitions is important, so we can do numerical
+ * comparisons (eg: < %WIMAX_ST_RADIO_OFF means the device is not ready
+ * to operate).
+ */
+/*
+ * The allowed state transitions are described in the table below
+ * (states in rows can go to states in columns where there is an X):
+ *
+ * UNINI RADIO READY SCAN CONNEC CONNEC
+ * NULL DOWN QUIESCING TIALIZED OFF NING TING TED

+ * - Initial implementation
+ *
+ *
+ * This header defines the data structures and constants used to
+ * communicate with the device.
+ *
+ * BOOTMODE/BOOTROM/FIRMWARE UPLOAD PROTOCOL
+ *
+ * The firmware upload protocol is quite simple and only requires a
+ * handful of commands. See drivers/net/wimax/i2400m/fw.c for more
+ * details.
+ *
+ * The BCF data structure is for the firmware file header.
+ *
+ *
+ * THE DATA / CONTROL PROTOCOL
+ *
+ * This is the normal protocol spoken with the device once the
+ * firmware is uploaded. It transports data payloads and control
+ * messages back and forth.
+ *
+ * It consists 'messages' that pack one or more payloads each. The
+ * format is described in detail in drivers/net/wimax/i2400m/rx.c and
+ * tx.c.
+ *
+ *
+ * THE L3L4 PROTOCOL
+ *
+ * The term L3L4 refers to Layer 3 (the device), Layer 4 (the
+ * driver/host software).
+ *
+ * This is the control protocol used by the host to control the i2400m
+ * device (scan, connect, disconnect...). This is sent to / received
+ * as control frames. These frames consist of a header and zero or
+ * more TLVs with information. We call each control frame a "message".
+ *
+ * Each message is composed of:
+ *
+ * HEADER
+ * [TLV0 + PAYLOAD0]
+ * [TLV1 + PAYLOAD1]
+ * [...]
+ * [TLVN + PAYLOADN]
+ *
+ * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are
+ * defined by a TLV structure (Type Length Value) which is a 'header'
+ * (struct i2400m_tlv_hdr) and then the payload.
+ *
+ * All integers are represented as Little Endian.
+ *
+ * - REQUESTS AND EVENTS
+ *
+ * The requests can be clasified as follows:
+ *
+ * COMMAND: implies a request from the host to the device requesting
+ * an action being performed. The device will reply with a
+ * message (with the same type as the command), status and
+ * no (TLV) payload. Execution of a command might cause
+ * events (of different type) to be sent later on as
+ * device's state changes.
+ *
+ * GET/SET: similar to COMMAND, but will not cause other
+ * EVENTs. The reply, in the case of GET, will contain
+ * TLVs with the requested information.
+ *
+ * EVENT: asynchronous messages sent from the device, maybe as a
+ * consequence of previous COMMANDs but disassociated from
+ * them.
+ *
+ * Only one request might be pending at the same time (ie: don't
+ * parallelize nor post another GET request before the previous
+ * COMMAND has been acknowledged with it's corresponding reply by the
+ * device).
+ *
+ * The different requests and their formats are described below:
+ *
+ * I2400M_MT_* Message types
+ * I2400M_MS_* Message status (for replies, events)
+ * i2400m_tlv_* TLVs
+ *
+ * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the
+ * operation.

+/*
+ * Initial APIs (1996 -> onward) :
+ * -----------------------------
+ * Basically, the wireless extensions are for now a set of standard ioctl
+ * call + /proc/net/wireless
+ *
+ * The entry /proc/net/wireless give statistics and information on the
+ * driver.
+ * This is better than having each driver having its entry because
+ * its centralised and we may remove the driver module safely.
+ *
+ * Ioctl are used to configure the driver and issue commands. This is
+ * better than command line options of insmod because we may want to
+ * change dynamically (while the driver is running) some parameters.
+ *
+ * The ioctl mechanimsm are copied from standard devices ioctl.
+ * We have the list of command plus a structure descibing the
+ * data exchanged...
+ * Note that to add these ioctl, I was obliged to modify :
+ * # net/core/dev.c (two place + add include)
+ * # net/ipv4/af_inet.c (one place + add include)
+ *
+ * /proc/net/wireless is a copy of /proc/net/dev.
+ * We have a structure for data passed from the driver to /proc/net/wireless
+ * Too add this, I've modified :
+ * # net/core/dev.c (two other places)
+ * # include/linux/netdevice.h (one place)
+ * # include/linux/proc_fs.h (one place)
+ *
+ * New driver API (2002 -> onward) :
+ * -------------------------------
+ * This file is only concerned with the user space API and common definitions.
+ * The new driver API is defined and documented in :
+ * # include/net/iw_handler.h
+ *
+ * Note as well that /proc/net/wireless implementation has now moved in :
+ * # net/core/wireless.c
+ *
+ * Wireless Events (2002 -> onward) :
+ * --------------------------------
+ * Events are defined at the end of this file, and implemented in :
+ * # net/core/wireless.c
+ *
+ * Other comments :
+ * --------------
+ * Do not add here things that are redundant with other mechanisms
+ * (drivers init, ifconfig, /proc/net/dev, ...) and with are not
+ * wireless specific.
+ *
+ * These wireless extensions are not magic : each driver has to provide
+ * support for them...
+ *
+ * IMPORTANT NOTE : As everything in the kernel, this is very much a
+ * work in progress. Contact me if you have ideas of improvements...

+/*
+ * UBI device creation (the same as MTD device attachment)
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * MTD devices may be attached using %UBI_IOCATT ioctl command of the UBI
+ * control device. The caller has to properly fill and pass
+ * &struct ubi_attach_req object - UBI will attach the MTD device specified in
+ * the request and return the newly created UBI device number as the ioctl
+ * return value.
+ *
+ * UBI device deletion (the same as MTD device detachment)
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * An UBI device maybe deleted with %UBI_IOCDET ioctl command of the UBI
+ * control device.
+ *
+ * UBI volume creation
+ * ~~~~~~~~~~~~~~~~~~~
+ *
+ * UBI volumes are created via the %UBI_IOCMKVOL ioctl command of UBI character
+ * device. A &struct ubi_mkvol_req object has to be properly filled and a
+ * pointer to it has to be passed to the ioctl.
+ *
+ * UBI volume deletion
+ * ~~~~~~~~~~~~~~~~~~~
+ *
+ * To delete a volume, the %UBI_IOCRMVOL ioctl command of the UBI character
+ * device should be used. A pointer to the 32-bit volume ID hast to be passed
+ * to the ioctl.
+ *
+ * UBI volume re-size
+ * ~~~~~~~~~~~~~~~~~~
+ *
+ * To re-size a volume, the %UBI_IOCRSVOL ioctl command of the UBI character
+ * device should be used. A &struct ubi_rsvol_req object has to be properly
+ * filled and a pointer to it has to be passed to the ioctl.
+ *
+ * UBI volumes re-name
+ * ~~~~~~~~~~~~~~~~~~~
+ *
+ * To re-name several volumes atomically at one go, the %UBI_IOCRNVOL command
+ * of the UBI character device should be used. A &struct ubi_rnvol_req object
+ * has to be properly filled and a pointer to it has to be passed to the ioctl.
+ *
+ * UBI volume update
+ * ~~~~~~~~~~~~~~~~~
+ *
+ * Volume update should be done via the %UBI_IOCVOLUP ioctl command of the
+ * corresponding UBI volume character device. A pointer to a 64-bit update
+ * size should be passed to the ioctl. After this, UBI expects user to write
+ * this number of bytes to the volume character device. The update is finished
+ * when the claimed number of bytes is passed. So, the volume update sequence
+ * is something like:
+ *
+ * fd = open("/dev/my_volume");
+ * ioctl(fd, UBI_IOCVOLUP, &image_size);
+ * write(fd, buf, image_size);
+ * close(fd);
+ *
+ * Logical eraseblock erase
+ * ~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To erase a logical eraseblock, the %UBI_IOCEBER ioctl command of the
+ * corresponding UBI volume character device should be used. This command
+ * unmaps the requested logical eraseblock, makes sure the corresponding
+ * physical eraseblock is successfully erased, and returns.
+ *
+ * Atomic logical eraseblock change
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * Atomic logical eraseblock change operation is called using the %UBI_IOCEBCH
+ * ioctl command of the corresponding UBI volume character device. A pointer to
+ * a &struct ubi_leb_change_req object has to be passed to the ioctl. Then the
+ * user is expected to write the requested amount of bytes (similarly to what
+ * should be done in case of the "volume update" ioctl).
+ *
+ * Logical eraseblock map
+ * ~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To map a logical eraseblock to a physical eraseblock, the %UBI_IOCEBMAP
+ * ioctl command should be used. A pointer to a &struct ubi_map_req object is
+ * expected to be passed. The ioctl maps the requested logical eraseblock to
+ * a physical eraseblock and returns. Only non-mapped logical eraseblocks can
+ * be mapped. If the logical eraseblock specified in the request is already
+ * mapped to a physical eraseblock, the ioctl fails and returns error.
+ *
+ * Logical eraseblock unmap
+ * ~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To unmap a logical eraseblock to a physical eraseblock, the %UBI_IOCEBUNMAP
+ * ioctl command should be used. The ioctl unmaps the logical eraseblocks,
+ * schedules corresponding physical eraseblock for erasure, and returns. Unlike
+ * the "LEB erase" command, it does not wait for the physical eraseblock being
+ * erased. Note, the side effect of this is that if an unclean reboot happens
+ * after the unmap ioctl returns, you may find the LEB mapped again to the same
+ * physical eraseblock after the UBI is run again.
+ *
+ * Check if logical eraseblock is mapped
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To check if a logical eraseblock is mapped to a physical eraseblock, the
+ * %UBI_IOCEBISMAP ioctl command should be used. It returns %0 if the LEB is
+ * not mapped, and %1 if it is mapped.
+ *
+ * Set an UBI volume property
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To set an UBI volume property the %UBI_IOCSETPROP ioctl command should be
+ * used. A pointer to a &struct ubi_set_vol_prop_req object is expected to be
+ * passed. The object describes which property should be set, and to which value
+ * it should be set.
+ *
+ * Block devices on UBI volumes
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * To create a R/O block device on top of an UBI volume the %UBI_IOCVOLCRBLK
+ * should be used. A pointer to a &struct ubi_blkcreate_req object is expected
+ * to be passed, which is not used and reserved for future usage.
+ *
+ * Conversely, to remove a block device the %UBI_IOCVOLRMBLK should be used,
+ * which takes no arguments.

+ * @max_beb_per1024: maximum expected number of bad PEB per 1024 PEBs
+ * @padding: reserved for future, not used, has to be zeroed
+ *
+ * This data structure is used to specify MTD device UBI has to attach and the
+ * parameters it has to use. The number which should be assigned to the new UBI
+ * device is passed in @ubi_num. UBI may automatically assign the number if
+ * @UBI_DEV_NUM_AUTO is passed. In this case, the device number is returned in
+ * @ubi_num.
+ *
+ * Most applications should pass %0 in @vid_hdr_offset to make UBI use default
+ * offset of the VID header within physical eraseblocks. The default offset is
+ * the next min. I/O unit after the EC header. For example, it will be offset
+ * 512 in case of a 512 bytes page NAND flash with no sub-page support. Or
+ * it will be 512 in case of a 2KiB page NAND flash with 4 512-byte sub-pages.
+ *
+ * But in rare cases, if this optimizes things, the VID header may be placed to
+ * a different offset. For example, the boot-loader might do things faster if
+ * the VID header sits at the end of the first 2KiB NAND page with 4 sub-pages.
+ * As the boot-loader would not normally need to read EC headers (unless it
+ * needs UBI in RW mode), it might be faster to calculate ECC. This is weird
+ * example, but it real-life example. So, in this example, @vid_hdr_offer would
+ * be 2KiB-64 bytes = 1984. Note, that this position is not even 512-bytes
+ * aligned, which is OK, as UBI is clever enough to realize this is 4th
+ * sub-page of the first page and add needed padding.
+ *
+ * The @max_beb_per1024 is the maximum amount of bad PEBs UBI expects on the
+ * UBI device per 1024 eraseblocks. This value is often given in an other form
+ * in the NAND datasheet (min NVB i.e. minimal number of valid blocks). The
+ * maximum expected bad eraseblocks per 1024 is then:
+ * 1024 * (1 - MinNVB / MaxNVB)
+ * Which gives 20 for most NAND devices. This limit is used in order to derive
+ * amount of eraseblock UBI reserves for handling new bad blocks. If the device
+ * has more bad eraseblocks than this limit, UBI does not reserve any physical
+ * eraseblocks for new bad eraseblocks, but attempts to use available
+ * eraseblocks (if any). The accepted range is 0-768. If 0 is given, the
+ * default kernel value of %CONFIG_MTD_UBI_BEB_LIMIT will be used.

+ * GTF_permit_access: Frame to which access is permitted.
+ * GTF_accept_transfer: Pseudo-phys frame slot being filled by new
+ * frame, or zero if none.
+ * 3. Write memory barrier (WMB).
+ * 4. Write ent->flags, inc. valid type.
+ *
+ * Invalidating an unused GTF_permit_access entry:
+ * 1. flags = ent->flags.
+ * 2. Observe that !(flags & (GTF_reading|GTF_writing)).
+ * 3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ * NB. No need for WMB as reuse of entry is control-dependent on success of
+ * step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *
+ * Invalidating an in-use GTF_permit_access entry:
+ * This cannot be done directly. Request assistance from the domain controller
+ * which can set a timeout on the use of a grant entry and take necessary

+ * Discard operation is a request for the underlying block device to mark

+ * will be erased from the device - it is just a hint to the device
+ * controller that these blocks are no longer in use. What the device
+ * controller does with that information is left to the controller.
+ * Discard operations are passed with sector_number as the
+ * sector index to begin discard operations at and nr_sectors as the number of
+ * sectors to be discarded. The specified sectors should be discarded if the
+ * underlying block device supports trim (ATA) or unmap (SCSI) operations,
+ * or a BLKIF_RSP_EOPNOTSUPP should be returned.

+ * The backend can optionally provide three extra XenBus attributes to
+ * further optimize the discard functionality:
+ * 'discard-alignment' - Devices that support discard functionality may
+ * internally allocate space in units that are bigger than the exported
+ * logical block size. The discard-alignment parameter indicates how many bytes
+ * the beginning of the partition is offset from the internal allocation unit's
+ * natural alignment.
+ * 'discard-granularity' - Devices that support discard functionality may
+ * internally allocate space using units that are bigger than the logical block
+ * size. The discard-granularity parameter indicates the size of the internal
+ * allocation unit in bytes if reported by the device. Otherwise the
+ * discard-granularity will be set to match the device's physical block size.
+ * 'discard-secure' - All copies of the discarded sectors (potentially created
+ * by garbage collection) must also be erased. To use this feature, the flag
+ * BLKIF_DISCARD_SECURE must be set in the blkif_request_trim.

+ * Older implementation of Xen network frontend / backend has an
+ * implicit dependency on the MAX_SKB_FRAGS as the maximum number of
+ * ring slots a skb can use. Netfront / netback may not work as
+ * expected when frontend and backend have different MAX_SKB_FRAGS.
+ *
+ * A better approach is to add mechanism for netfront / netback to
+ * negotiate this value. However we cannot fix all possible
+ * frontends, so we need to define a value which states the minimum
+ * slots backend must support.
+ *
+ * The minimum value derives from older Linux kernel's MAX_SKB_FRAGS
+ * (18), which is proved to work with most frontends. Any new backend
+ * which doesn't negotiate with frontend should expect frontend to
+ * send a valid packet using slots up to this value.

+ * the appropriate req_event or rsp_event field in the shared ring.
+ * If the client sends notification for rx requests then it should specify

+ * that it cannot safely queue packets (as it may not be kicked to send them).

+ /*
+ * "feature-split-event-channels" is introduced to separate guest TX

+ * advertise it via xenstore as 0 (disabled) or 1 (enabled).
+ *
+ * To make use of this feature, frontend should allocate two event
+ * channels for TX and RX, advertise them to backend as
+ * "event-channel-tx" and "event-channel-rx" respectively. If frontend
+ * doesn't want to use this feature, it just writes "event-channel"
+ * node as before.
+ */
+
+/*
+ * Multiple transmit and receive queues:
+ * If supported, the backend will write the key "multi-queue-max-queues" to
+ * the directory for that vif, and set its value to the maximum supported
+ * number of queues.
+ * Frontends that are aware of this feature and wish to use it can write the
+ * key "multi-queue-num-queues", set to the number they wish to use, which
+ * must be greater than zero, and no more than the value reported by the backend
+ * in "multi-queue-max-queues".
+ *
+ * Queues replicate the shared rings and event channels.
+ * "feature-split-event-channels" may optionally be used when using
+ * multiple queues, but is not mandatory.
+ *
+ * Each queue consists of one shared ring pair, i.e. there must be the same
+ * number of tx and rx rings.
+ *
+ * For frontends requesting just one queue, the usual event-channel and
+ * ring-ref keys are written as before, simplifying the backend processing
+ * to avoid distinguishing between a frontend that doesn't understand the
+ * multi-queue feature, and one that does, but requested only one queue.
+ *
+ * Frontends requesting two or more queues must not write the toplevel
+ * event-channel (or event-channel-{tx,rx}) and {tx,rx}-ring-ref keys,
+ * instead writing those keys under sub-keys having the name "queue-N" where
+ * N is the integer ID of the queue for which those keys belong. Queues
+ * are indexed from zero. For example, a frontend with two queues and split
+ * event channels must write the following set of queue-related keys:
+ *
+ * /local/domain/1/device/vif/0/multi-queue-num-queues = "2"
+ * /local/domain/1/device/vif/0/queue-0 = ""
+ * /local/domain/1/device/vif/0/queue-0/tx-ring-ref = "<ring-ref-tx0>"
+ * /local/domain/1/device/vif/0/queue-0/rx-ring-ref = "<ring-ref-rx0>"
+ * /local/domain/1/device/vif/0/queue-0/event-channel-tx = "<evtchn-tx0>"
+ * /local/domain/1/device/vif/0/queue-0/event-channel-rx = "<evtchn-rx0>"
+ * /local/domain/1/device/vif/0/queue-1 = ""
+ * /local/domain/1/device/vif/0/queue-1/tx-ring-ref = "<ring-ref-tx1>"
+ * /local/domain/1/device/vif/0/queue-1/rx-ring-ref = "<ring-ref-rx1"
+ * /local/domain/1/device/vif/0/queue-1/event-channel-tx = "<evtchn-tx1>"
+ * /local/domain/1/device/vif/0/queue-1/event-channel-rx = "<evtchn-rx1>"
+ *
+ * If there is any inconsistency in the XenStore data, the backend may
+ * choose not to connect any queues, instead treating the request as an
+ * error. This includes scenarios where more (or fewer) queues were
+ * requested than the frontend provided details for.
+ *
+ * Mapping of packets to queues is considered to be a function of the
+ * transmitting system (backend or frontend) and is not negotiated
+ * between the two. Guests are free to transmit packets on any queue
+ * they choose, provided it has been set up correctly. Guests must be

+ *
+ * Sub-commands: ptr[1:0] specifies the appropriate MMU_* command.
+ * -------------
+ * ptr[1:0] == MMU_NORMAL_PT_UPDATE:
+ * Updates an entry in a page table belonging to PFD. If updating an L1 table,
+ * and the new table entry is valid/present, the mapped frame must belong to
+ * FD. If attempting to map an I/O page then the caller assumes the privilege
+ * of the FD.
+ * FD == DOMID_IO: Permit /only/ I/O mappings, at the priv level of the caller.
+ * FD == DOMID_XEN: Map restricted areas of Xen's heap space.
+ * ptr[:2] -- Machine address of the page-table entry to modify.
+ * val -- Value to write.
+ *
+ * There also certain implicit requirements when using this hypercall. The
+ * pages that make up a pagetable must be mapped read-only in the guest.
+ * This prevents uncontrolled guest updates to the pagetable. Xen strictly
+ * enforces this, and will disallow any pagetable update which will end up
+ * mapping pagetable page RW, and will disallow using any writable page as a
+ * pagetable. In practice it means that when constructing a page table for a
+ * process, thread, etc, we MUST be very dilligient in following these rules:
+ * 1). Start with top-level page (PGD or in Xen language: L4). Fill out
+ * the entries.
+ * 2). Keep on going, filling out the upper (PUD or L3), and middle (PMD
+ * or L2).
+ * 3). Start filling out the PTE table (L1) with the PTE entries. Once
+ * done, make sure to set each of those entries to RO (so writeable bit
+ * is unset). Once that has been completed, set the PMD (L2) for this
+ * PTE table as RO.
+ * 4). When completed with all of the PMD (L2) entries, and all of them have
+ * been set to RO, make sure to set RO the PUD (L3). Do the same
+ * operation on PGD (L4) pagetable entries that have a PUD (L3) entry.
+ * 5). Now before you can use those pages (so setting the cr3), you MUST also
+ * pin them so that the hypervisor can verify the entries. This is done
+ * via the HYPERVISOR_mmuext_op(MMUEXT_PIN_L4_TABLE, guest physical frame
+ * number of the PGD (L4)). And this point the HYPERVISOR_mmuext_op(
+ * MMUEXT_NEW_BASEPTR, guest physical frame number of the PGD (L4)) can be
+ * issued.
+ * For 32-bit guests, the L4 is not used (as there is less pagetables), so
+ * instead use L3.
+ * At this point the pagetables can be modified using the MMU_NORMAL_PT_UPDATE
+ * hypercall. Also if so desired the OS can also try to write to the PTE
+ * and be trapped by the hypervisor (as the PTE entry is RO).
+ *
+ * To deallocate the pages, the operations are the reverse of the steps
+ * mentioned above. The argument is MMUEXT_UNPIN_TABLE for all levels and the
+ * pagetable MUST not be in use (meaning that the cr3 is not set to it).
+ *
+ * ptr[1:0] == MMU_MACHPHYS_UPDATE:
+ * Updates an entry in the machine->pseudo-physical mapping table.
+ * ptr[:2] -- Machine address within the frame whose mapping to modify.
+ * The frame must belong to the FD, if one is specified.
+ * val -- Value to write into the mapping entry.
+ *
+ * ptr[1:0] == MMU_PT_UPDATE_PRESERVE_AD:
+ * As MMU_NORMAL_PT_UPDATE above, but A/D bits currently in the PTE are ORed
+ * with those in @val.
+ *
+ * @val is usually the machine frame number along with some attributes.
+ * The attributes by default follow the architecture defined bits. Meaning that
+ * if this is a X86_64 machine and four page table layout is used, the layout
+ * of val is:
+ * - 63 if set means No execute (NX)
+ * - 46-13 the machine frame number
+ * - 12 available for guest
+ * - 11 available for guest
+ * - 10 available for guest
+ * - 9 available for guest
+ * - 8 global
+ * - 7 PAT (PSE is disabled, must use hypercall to make 4MB or 2MB pages)
+ * - 6 dirty
+ * - 5 accessed
+ * - 4 page cached disabled
+ * - 3 page write through
+ * - 2 userspace accessible
+ * - 1 writeable
+ * - 0 present
+ *
+ * The one bits that does not fit with the default layout is the PAGE_PSE
+ * also called PAGE_PAT). The MMUEXT_[UN]MARK_SUPER arguments to the
+ * HYPERVISOR_mmuext_op serve as mechanism to set a pagetable to be 4MB
+ * (or 2MB) instead of using the PAGE_PSE bit.
+ *
+ * The reason that the PAGE_PSE (bit 7) is not being utilized is due to Xen
+ * using it as the Page Attribute Table (PAT) bit - for details on it please
+ * refer to Intel SDM 10.12. The PAT allows to set the caching attributes of
+ * pages instead of using MTRRs.
+ *
+ * The PAT MSR is as follows (it is a 64-bit value, each entry is 8 bits):
+ * PAT4 PAT0
+ * +-----+-----+----+----+----+-----+----+----+
+ * | UC | UC- | WC | WB | UC | UC- | WC | WB | <= Linux
+ * +-----+-----+----+----+----+-----+----+----+
+ * | UC | UC- | WT | WB | UC | UC- | WT | WB | <= BIOS (default when machine boots)
+ * +-----+-----+----+----+----+-----+----+----+
+ * | rsv | rsv | WP | WC | UC | UC- | WT | WB | <= Xen
+ * +-----+-----+----+----+----+-----+----+----+
+ *
+ * The lookup of this index table translates to looking up
+ * Bit 7, Bit 4, and Bit 3 of val entry:
+ *
+ * PAT/PSE (bit 7) ... PCD (bit 4) .. PWT (bit 3).
+ *
+ * If all bits are off, then we are using PAT0. If bit 3 turned on,
+ * then we are using PAT1, if bit 3 and bit 4, then PAT2..
+ *
+ * As you can see, the Linux PAT1 translates to PAT4 under Xen. Which means
+ * that if a guest that follows Linux's PAT setup and would like to set Write
+ * Combined on pages it MUST use PAT4 entry. Meaning that Bit 7 (PAGE_PAT) is
+ * set. For example, under Linux it only uses PAT0, PAT1, and PAT2 for the
+ * caching as:
+ *
+ * WB = none (so PAT0)
+ * WC = PWT (bit 3 on)
+ * UC = PWT | PCD (bit 3 and 4 are on).
+ *
+ * To make it work with Xen, it needs to translate the WC bit as so:
+ *
+ * PWT (so bit 3 on) --> PAT (so bit 7 is on) and clear bit 3
+ *
+ * And to translate back it would:
+ *
+ * PAT (bit 7 on) --> PWT (bit 3 on) and clear bit 7.
