Add the rt linux 4.1.3-rt3 as base

Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> We lose all the git history this way and it's not good. We should apply another opnfv project repo in future. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+/* Note that the cx25840 driver requires that the bridge driver calls the
+   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
+   3) which DSP input to use for each DSP output
+
+   And in the 'output' arg of the s_routing function you specify:
+
+   1) which SCART input to use for each SCART output
+
+   Depending on how the msp is wired to the other components you can
+   ignore or mute certain inputs or outputs.
+

+/*
+ * 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.

+
+   Usually these devices are controlled through an i2c bus, but other busses
+   may also be used.
+
+   The v4l2_subdev struct provides a way of accessing these devices in a
+   generic manner. Most operations that these sub-devices support fall in
+   a few categories: core ops, audio ops, video ops and tuner ops.
+
+   More categories can be added if needed, although this should remain a
+   limited set (no more than approx. 8 categories).
+
+   Each category has its own set of ops that subdev drivers can implement.
+
+   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.
+ */
+
+/* Core ops: it is highly recommended to implement at least these ops:
+
+   log_status
+   g_register
+   s_register
+
+   This provides basic debugging support.
+
+   The ioctl ops is meant for generic ioctl-like commands. Depending on
+   the use-case it might be better to use subdev-specific ops (currently
+   not yet implemented) since ops provide proper type-checking.

+ *		argument is the allocator private per-buffer structure
+ *		previously returned from the alloc callback.
+ * @get_userptr: acquire userspace memory for a hardware operation; used for

+ *		   from the attach_dmabuf callback.
+ * @map_dmabuf: request for access to the dmabuf from allocator; the allocator
+ *		of dmabuf is informed that this driver is going to use the

+ *		  that this driver is done using the dmabuf for now.

+/**
+ * struct vb2_ops - driver-specific callbacks
+ *
+ * @queue_setup:	called from VIDIOC_REQBUFS and VIDIOC_CREATE_BUFS
+ *			handlers before memory allocation, or, if
+ *			*num_planes != 0, after the allocation to verify a
+ *			smaller number of buffers. Driver should return
+ *			the required number of buffers in *num_buffers, the
+ *			required number of planes per buffer in *num_planes; the
+ *			size of each plane should be set in the sizes[] array
+ *			and optional per-plane allocator specific context in the
+ *			alloc_ctxs[] array. When called from VIDIOC_REQBUFS,
+ *			fmt == NULL, the driver has to use the currently
+ *			configured format and *num_buffers is the total number
+ *			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.

+ * @io_modes:	supported io methods (see vb2_io_modes enum)
+ * @fileio_read_once:		report EOF after reading the first buffer
+ * @fileio_write_immediately:	queue buffer after each write() call
+ * @allow_zero_bytesused:	allow bytesused == 0 to be passed to the driver
+ * @lock:	pointer to a mutex that protects the vb2_queue struct. The
+ *		driver can set this to a mutex to let the v4l2 core serialize
+ *		the queuing ioctls. If the driver wants to handle locking
+ *		itself, then this should be set to NULL. This lock is not used
+ *		by the videobuf2 core API.
+ * @owner:	The filehandle that 'owns' the buffers, i.e. the filehandle
+ *		that called reqbufs, create_buffers or started fileio.
+ *		This field is not used by the videobuf2 core API, but it allows
+ *		drivers to easily associate an owner filehandle with the queue.
+ * @ops:	driver-specific callbacks
+ * @mem_ops:	memory allocator specific callbacks
+ * @drv_priv:	driver private data
+ * @buf_struct_size: size of the driver-specific buffer structure;
+ *		"0" indicates the driver doesn't want to use a custom buffer
+ *		structure type, so sizeof(struct vb2_buffer) will is used
+ * @timestamp_flags: Timestamp flags; V4L2_BUF_FLAG_TIMESTAMP_* and
+ *		V4L2_BUF_FLAG_TSTAMP_SRC_*
+ * @gfp_flags:	additional gfp flags used when allocating the buffers.
+ *		Typically this is 0, but it may be e.g. GFP_DMA or __GFP_DMA32
+ *		to force the buffer allocation to a specific memory zone.
+ * @min_buffers_needed: the minimum number of buffers needed before
+ *		start_streaming() can be called. Used when a DMA engine
+ *		cannot be started unless at least this number of buffers
+ *		have been queued into the driver.
+ *
+ * @mmap_lock:	private mutex used when buffers are allocated/freed/mmapped
+ * @memory:	current memory type used
+ * @bufs:	videobuf buffer structures
+ * @num_buffers: number of allocated/used buffers
+ * @queued_list: list of buffers currently queued from userspace
+ * @queued_count: number of buffers queued and ready for streaming.
+ * @owned_by_drv_count: number of buffers owned by the driver
+ * @done_list:	list of buffers ready to be dequeued to userspace
+ * @done_lock:	lock to protect done_list list
+ * @done_wq:	waitqueue for processes waiting for buffers ready to be dequeued
+ * @alloc_ctx:	memory type/allocator-specific contexts for each plane
+ * @streaming:	current streaming state
+ * @start_streaming_called: start_streaming() was called successfully and we
+ *		started streaming.
+ * @error:	a fatal error occurred on the queue
+ * @waiting_for_buffers: used in poll() to check if vb2 is still waiting for
+ *		buffers. Only set for capture queues if qbuf has not yet been
+ *		called since poll() needs to return POLLERR in that situation.
+ * @fileio:	file io emulator internal data, used only if emulator is active
+ * @threadio:	thread io internal data, used only if thread is active
