+made outside of this for modularising the sound
+
+Changelog for version 3.8o
+--------------------------
+
+Since 3.8h
+- Included support for OPL3-SA1 and SoftOSS
+
+Since 3.8
+- Fixed SNDCTL_DSP_GETOSPACE
+- Compatibility fixes for Linux 2.1.47
+
+Since 3.8-beta21
+- Fixed all known bugs (I think).
+
+Since 3.8-beta8
+- Lot of fixes to audio playback code in dmabuf.c
+
+Since 3.8-beta6
+- Fixed the famous Quake delay bug.
+
+Since 3.8-beta5
+- Fixed many bugs in audio playback.
+
+Since 3.8-beta4
+- Just minor changes.
+
+Since 3.8-beta1
+- Major rewrite of audio playback handling.
+- Added AWE32 support by Takashi Iwai (in ./lowlevel/).
+
+Since 3.7-beta#
+- Passing of ioctl() parameters between soundcard.c and other modules has been
+changed so that arg always points to kernel space.
+- Some bugfixes.
+
+Since 3.7-beta5
+- Disabled MIDI input with GUS PnP (Interwave). There seems to be constant
+stream of received 0x00 bytes when the MIDI receiver is enabled.
+
+Since 3.5
+- Changes almost everywhere.
+- Support for OPTi 82C924-based sound cards.
+
+Since 3.5.4-beta8
+- Fixed a bug in handling of non-fragment sized writes in 16 bit/stereo mode
+ with GUS.
+- Limited minimum fragment size with some audio devices (GUS=512 and
+ SB=32). These devices require more time to "recover" from processing
+ of each fragment.
+
+Since 3.5.4-beta6/7
+- There seems to be problems in the OPTi 82C930 so cards based on this
+ chip don't necessarily work yet. There are problems in detecting the
+ MIDI interface. Also mixer volumes may be seriously wrong on some systems.
+ You can safely use this driver version with C930 if it looks to work.
+ However please don't complain if you have problems with it. C930 support
+ should be fixed in future releases.
+- Got initialization of GUS PnP to work. With this version GUS PnP should
+ work in GUS compatible mode after initialization using isapnptools.
+- Fixed a bug in handling of full duplex cards in write only mode. This has
+ been causing "audio device opening" errors with RealAudio player.
+
+Since 3.5.4.beta5
+- Changes to OPTi 82C930 driver.
+- Major changes to the Soundscape driver. The driver requires now just one
+ DMA channel. The extra audio/dsp device (the "Not functional" one) used
+ for code download in the earlier versions has been eliminated. There is now
+ just one /dev/dsp# device which is used both for code download and audio.
+
+Since 3.5.4.beta4
+- Minor changes.
+
+Since 3.5.4-beta2
+- Fixed silent playback with ESS 688/1688.
+- Got SB16 to work without the 16 bit DMA channel (only the 8 bit one
+ is required for 8 and 16 bit modes).
+- Added the "lowlevel" subdirectory for additional low level drivers that
+ are not part of USS core. See lowlevel/README for more info.
+- Included support for ACI mixer (by Markus Kuhn). ACI is a mixer used in
+ miroPCM sound cards. See lowlevel/aci.readme for more info.
+- Support for Aztech Washington chipset (AZT2316 ASIC).
+
+Since 3.5.4-beta1
+- Reduced clicking with AD1848.
+- Support for OPTi 82C930. Only half duplex at this time. 16 bit playback
+ is sometimes just white noise (occurs randomly).
+
+Since 3.5.2
+- Major changes to the SB/Jazz16/ESS driver (most parts rewritten).
+ The most noticeable new feature is support for multiple SB cards at the same
+ time.
+- Renamed sb16_midi.c to uart401.c. Also modified it to work also with
+ other MPU401 UART compatible cards than SB16/ESS/Jazz.
+- Some changes which reduce clicking in audio playback.
+- Copying policy is now GPL.
+
+Since 3.5.1
+- TB Maui initialization support
+Since 3.5
+- Improved handling of playback underrun situations.
+
+Since 3.5-beta10
+- Bug fixing
+
+Since 3.5-beta9
+- Fixed for compatibility with Linux 1.3.70 and later.
+- Changed boot time passing of 16 bit DMA channel number to SB driver.
+
+Since 3.5-beta8
+- Minor changes
+
+Since 3.5-beta7
+- enhancements to configure program (by Jeff Tranter):
+ - prompts are in same format as 1.3.x Linux kernel config program
+ - on-line help for each question
+ - fixed some compile warnings detected by gcc/g++ -Wall
+ - minor grammatical changes to prompts
+
+Since 3.5-beta6
+- Fixed bugs in mmap() support.
+- Minor changes to Maui driver.
+
+Since 3.5-beta5
+- Fixed crash after recording with ESS688. It's generally a good
+ idea to stop inbound DMA transfers before freeing the memory
+ buffer.
+- Fixed handling of AD1845 codec (for example Shuttle Sound System).
+- Few other fixes.
+
+Since 3.5-beta4
+- Fixed bug in handling of uninitialized instruments with GUS.
+
+Since 3.5-beta3
+- Few changes which decrease popping at end/beginning of audio playback.
+
+Since 3.5-beta2
+- Removed MAD16+CS4231 hack made in previous version since it didn't
+ help.
+- Fixed the above bug in proper way and in proper place. Many thanks
+ to James Hightower.
+
+Since 3.5-beta1
+- Bug fixes.
+- Full duplex audio with MAD16+CS4231 may work now. The driver configures
+ SB DMA of MAD16 so that it doesn't conflict with codec's DMA channels.
+ The side effect is that all 8 bit DMA channels (0,1,3) are populated in
+ duplex mode.
+
+Since 3.5-alpha9
+- Bug fixes (mostly in Jazz16 and ESS1688/688 supports).
+- Temporarily disabled recording with ESS1688/688 since it causes crash.
+- Changed audio buffer partitioning algorithm so that it selects
+ smaller fragment size than earlier. This improves real time capabilities
+ of the driver and makes recording to disk to work better. Unfortunately
+ this change breaks some programs which assume that fragments cannot be
+ shorter than 4096 bytes.
+
+Since 3.5-alpha8
+- Bug fixes
+
+Since 3.5-alpha7
+- Linux kernel compatible configuration (_EXPERIMENTAL_). Enable
+ using command "cd /linux/drivers/sound;make script" and then
+ just run kernel's make config normally.
+- Minor fixes to the SB support. Hopefully the driver works with
+ all SB models now.
+- Added support for ESS ES1688 "AudioDrive" based cards.
+
+Since 3.5-alpha6
+- SB Pro and SB16 supports are no longer separately selectable options.
+ Enabling SB enables them too.
+- Changed all #ifndef EXCLUDE_xx stuff to #ifdef CONFIG_xx. Modified
+configure to handle this.
+- Removed initialization messages from the
+modularized version. They can be enabled by using init_trace=1 in
+the insmod command line (insmod sound init_trace=1).
+- More AIX stuff.
+- Added support for synchronizing dsp/audio devices with /dev/sequencer.
+- mmap() support for dsp/audio devices.
+
+Since 3.5-alpha5
+- AIX port.
+- Changed some xxx_PATCH macros in soundcard.h to work with
+ big endian machines.
+
+Since 3.5-alpha4
+- Removed the 'setfx' stuff from the version distributed with kernel
+ sources. Running 'setfx' is required again.
+
+Since 3.5-alpha3
+- Moved stuff from the 'setfx' program to the AudioTrix Pro driver.
+
+Since 3.5-alpha2
+- Modifications to makefile and configure.c. Unnecessary sources
+ are no longer compiled. Newly created local.h is also copied to
+ /etc/soundconf. "make oldconfig" reads /etc/soundconf and produces
+ new local.h which is compatible with current version of the driver.
+- Some fixes to the SB16 support.
+- Fixed random protection fault in gus_wave.c
+
+Since 3.5-alpha1
+- Modified to work with Linux-1.3.33 and later
+- Some minor changes
+
+Since 3.0.2
+- Support for CS4232 based PnP cards (AcerMagic S23 etc).
+- Full duplex support for some CS4231, CS4232 and AD1845 based cards
+(GUS MAX, AudioTrix Pro, AcerMagic S23 and many MAD16/Mozart cards
+having a codec mentioned above).
+- Almost fully rewritten loadable modules support.
+- Fixed some bugs.
+- Huge amount of testing (more testing is still required).
+- mmap() support (works with some cards). Requires much more testing.
+- Sample/patch/program loading for TB Maui/Tropez. No initialization
+since TB doesn't allow me to release that code.
+- Using CS4231 compatible codecs as timer for /dev/music.
+
+Since 3.0.1
+- Added allocation of I/O ports, DMA channels and interrupts
+to the initialization code. This may break modules support since
+the driver may not free some resources on unload. Should be fixed soon.
+
+Since 3.0
+- Some important bug fixes.
+- select() for /dev/dsp and /dev/audio (Linux only).
+(To use select() with read, you have to call read() to start
+the recording. Calling write() kills recording immediately so
+use select() carefully when you are writing a half duplex app.
+Full duplex mode is not implemented yet.) Select works also with
+/dev/sequencer and /dev/music. Maybe with /dev/midi## too.
+
+Since 3.0-beta2
+- Minor fixes.
+- Added Readme.cards
+
+Since 3.0-beta1
+- Minor fixes to the modules support.
+- Eliminated call to sb_free_irq() in ad1848.c
+- Rewritten MAD16&Mozart support (not tested with MAD16 Pro).
+- Fix to DMA initialization of PSS cards.
+- Some fixes to ad1848/cs42xx mixer support (GUS MAX, MSS, etc.)
+- Fixed some bugs in the PSS driver which caused I/O errors with
+ the MSS mode (/dev/dsp).
+
+Since 3.0-950506
+- Recording with GUS MAX fixed. It works when the driver is configured
+ to use two DMA channels with GUS MAX (16 bit ones recommended).
+
+Since 3.0-94xxxx
+- Too many changes
+
+Since 3.0-940818
+- Fixes for Linux 1.1.4x.
+- Disables Disney Sound System with SG NX Pro 16 (less noise).
+
+Since 2.90-2
+- Fixes to soundcard.h
+- Non blocking mode to /dev/sequencer
+- Experimental detection code for Ensoniq Soundscape.
+
+Since 2.90
+- Minor and major bug fixes
+
+Since pre-3.0-940712
+- GUS MAX support
+- Partially working MSS/WSS support (could work with some cards).
+- Hardware u-Law and A-Law support with AD1848/CS4248 and CS4231 codecs
+ (GUS MAX, GUS16, WSS etc). Hardware ADPCM is possible with GUS16 and
+ GUS MAX, but it doesn't work yet.
+Since pre-3.0-940426
+- AD1848/CS4248/CS4231 codec support (MSS, GUS MAX, Aztec, Orchid etc).
+This codec chip is used in various sound cards. This version is developed
+for the 16 bit daughtercard of GUS. It should work with other cards also
+if the following requirements are met:
+ - The I/O, IRQ and DMA settings are jumper selectable or
+ the card is initialized by booting DOS before booting Linux (etc.).
+ - You add the IO, IRQ and DMA settings manually to the local.h.
+ (Just define GUS16_BASE, GUS16_IRQ and GUS16_DMA). Note that
+ the base address bust be the base address of the codec chip not the
+ card itself. For the GUS16 these are the same but most MSS compatible
+ cards have the codec located at card_base+4.
+- Some minor changes
+
+Since 2.5 (******* MAJOR REWRITE ***********)
+
+This version is based on v2.3. I have tried to maintain two versions
+together so that this one should have the same features than v2.5.
+Something may still be missing. If you notice such things, please let me
+know.
+
+The Readme.v30 contains more details.
+
+- /dev/midi## devices.
+- /dev/sequencer2
+
+Since 2.5-beta2
+- Some fine tuning to the GUS v3.7 mixer code.
+- Fixed speed limits for the plain SB (1.0 to 2.0).
+
+Since 2.5-beta
+- Fixed OPL-3 detection with SB. Caused problems with PAS16.
+- GUS v3.7 mixer support.
+
+Since 2.4
+- Mixer support for Sound Galaxy NX Pro (define __SGNXPRO__ on your local.h).
+- Fixed truncated sound on /dev/dsp when the device is closed.
+- Linear volume mode for GUS
+- Pitch bends larger than +/- 2 octaves.
+- MIDI recording for SB and SB Pro. (Untested).
+- Some other fixes.
+- SB16 MIDI and DSP drivers only initialized if SB16 actually installed.
+- Implemented better detection for OPL-3. This should be useful if you
+ have an old SB Pro (the non-OPL-3 one) or a SB 2.0 clone which has a OPL-3.
+- SVR4.2 support by Ian Hartas. Initial ALPHA TEST version (untested).
+
+Since 2.3b
+- Fixed bug which made it impossible to make long recordings to disk.
+ Recording was not restarted after a buffer overflow situation.
+- Limited mixer support for GUS.
+- Numerous improvements to the GUS driver by Andrew Robinson. Including
+ some click removal etc.
+
+Since 2.3
+- Fixed some minor bugs in the SB16 driver.
+
+Since 2.2b
+- Full SB16 DSP support. 8/16 bit, mono/stereo
+- The SCO and FreeBSD versions should be in sync now. There are some
+ problems with SB16 and GUS in the FreeBSD versions.
+ The DMA buffer allocation of the SCO version has been polished but
+ there could still be some problems. At least it hogs memory.
+ The DMA channel
+ configuration method used in the SCO/System is a hack.
+- Support for the MPU emulation of the SB16.
+- Some big arrays are now allocated boot time. This makes the BSS segment
+ smaller which makes it possible to use the full driver with
+ NetBSD. These arrays are not allocated if no suitable sound card is available.
+- Fixed a bug in the compute_and_set_volume in gus_wave.c
+- Fixed the too fast mono playback problem of SB Pro and PAS16.
+
+Since 2.2
+- Stereo recording for SB Pro. Somehow it was missing and nobody
+ had noticed it earlier.
+- Minor polishing.
+- Interpreting of boot time arguments (sound=) for Linux.
+- Breakup of sb_dsp.c. Parts of the code has been moved to
+ sb_mixer.c and sb_midi.c
+
+Since 2.1
+- Preliminary support for SB16.
+ - The SB16 mixer is supported in its native mode.
+ - Digitized voice capability up to 44.1 kHz/8 bit/mono
+ (16 bit and stereo support coming in the next release).
+- Fixed some bugs in the digitized voice driver for PAS16.
+- Proper initialization of the SB emulation of latest PAS16 models.
+
+- Significantly improved /dev/dsp and /dev/audio support.
+ - Now supports half duplex mode. It's now possible to record and
+ playback without closing and reopening the device.
+ - It's possible to use smaller buffers than earlier. There is a new
+ ioctl(fd, SNDCTL_DSP_SUBDIVIDE, &n) where n should be 1, 2 or 4.
+ This call instructs the driver to use smaller buffers. The default
+ buffer size (0.5 to 1.0 seconds) is divided by n. Should be called
+ immediately after opening the device.
+
+Since 2.0
+Just cosmetic changes.

+
+ READ THIS
+
+ This module started to configure the Audio Excel DSP 16 Sound Card.
+ Now works with the SC-6000 (old aedsp16) and new SC-6600 based cards.
+
+ NOTE: I have NO idea about Audio Excel DSP 16 III. If someone owns this
+ audio card and want to see the kernel support for it, please contact me.
+
+ Audio Excel DSP 16 is an SB pro II, Microsoft Sound System and MPU-401
+ compatible card.
+ It is software-only configurable (no jumpers to hard-set irq/dma/mpu-irq),
+ so before this module, the only way to configure the DSP under linux was
+ boot the MS-DOS loading the sound.sys device driver (this driver soft-
+ configure the sound board hardware by massaging someone of its registers),
+ and then ctrl-alt-del to boot linux with the DSP configured by the DOS
+ driver.
+
+ This module works configuring your Audio Excel DSP 16's irq, dma and
+ mpu-401-irq. The OSS Lite routines rely on the fact that if the
+ hardware is there, they can detect it. The problem with AEDSP16 is
+ that no hardware can be found by the probe routines if the sound card
+ is not configured properly. Sometimes the kernel probe routines can find
+ an SBPRO even when the card is not configured (this is the standard setup
+ of the card), but the SBPRO emulation don't work well if the card is not
+ properly initialized. For this reason
+
+ aedsp16_init_board()
+
+ routine is called before the OSS Lite probe routines try to detect the
+ hardware.
+
+ NOTE (READ THE NOTE TOO, IT CONTAIN USEFUL INFORMATIONS)
+
+ NOTE: Now it works with SC-6000 and SC-6600 based audio cards. The new cards
+ have no jumper switch at all. No more WSS or MPU-401 I/O port switches. They
+ have to be configured by software.
+
+ NOTE: The driver is merged with the new OSS Lite sound driver. It works
+ as a lowlevel driver.
+
+ The Audio Excel DSP 16 Sound Card emulates both SBPRO and MSS;
+ the OSS Lite sound driver can be configured for SBPRO and MSS cards
+ at the same time, but the aedsp16 can't be two cards!!
+ When we configure it, we have to choose the SBPRO or the MSS emulation
+ for AEDSP16. We also can install a *REAL* card of the other type (see [1]).
+
+ NOTE: If someone can test the combination AEDSP16+MSS or AEDSP16+SBPRO
+ please let me know if it works.
+
+ The MPU-401 support can be compiled in together with one of the other
+ two operating modes.
+
+ NOTE: This is something like plug-and-play: we have only to plug
+ the AEDSP16 board in the socket, and then configure and compile
+ a kernel that uses the AEDSP16 software configuration capability.
+ No jumper setting is needed!
+
+ For example, if you want AEDSP16 to be an SBPro, on irq 10, dma 3
+ you have just to make config the OSS Lite package, configuring
+ the AEDSP16 sound card, then activating the SBPro emulation mode
+ and at last configuring IRQ and DMA.
+ Compile the kernel and run it.
+
+ NOTE: This means for SC-6000 cards that you can choose irq and dma,
+ but not the I/O addresses. To change I/O addresses you have to set
+ them with jumpers. For SC-6600 cards you have no jumpers so you have
+ to set up your full card configuration in the make config.
+
+ You can change the irq/dma/mirq settings WITHOUT THE NEED to open
+ your computer and massage the jumpers (there are no irq/dma/mirq
+ jumpers to be configured anyway, only I/O BASE values have to be
+ configured with jumpers)
+
+ For some ununderstandable reason, the card default of irq 7, dma 1,
+ don't work for me. Seems to be an IRQ or DMA conflict. Under heavy
+ HDD work, the kernel start to erupt out a lot of messages like:
+
+ 'Sound: DMA timed out - IRQ/DRQ config error?'
+
+ For what I can say, I have NOT any conflict at irq 7 (under linux I'm
+ using the lp polling driver), and dma line 1 is unused as stated by
+ /proc/dma. I can suppose this is a bug of AEDSP16. I know my hardware so
+ I'm pretty sure I have not any conflict, but may be I'm wrong. Who knows!
+ Anyway a setting of irq 10, dma 3 works really fine.
+
+ NOTE: if someone can use AEDSP16 with irq 7, dma 1, please let me know
+ the emulation mode, all the installed hardware and the hardware
+ configuration (irq and dma settings of all the hardware).
+
+ This init module should work with SBPRO+MSS, when one of the two is
+ the AEDSP16 emulation and the other the real card. (see [1])
+ For example:
+
+ AEDSP16 (0x220) in SBPRO emu (0x220) + real MSS + other
+ AEDSP16 (0x220) in MSS emu + real SBPRO (0x240) + other
+
+ MPU401 should work. (see [2])

+
+ TODO, WISHES AND TECH
+
+ - About I/O ports allocation -
+
+ Request the 2x0h region (port base) in any case if we are using this card.
+
+ NOTE: the "aedsp16 (base)" string with which we are requesting the aedsp16
+ port base region (see code) does not mean necessarily that we are emulating
+ sbpro. Even if this region is the sbpro I/O ports region, we use this
+ region to access the control registers of the card, and if emulating
+ sbpro, I/O sbpro registers too. If we are emulating MSS, the sbpro
+ registers are not used, in no way, to emulate an sbpro: they are
+ used only for configuration purposes.
+
+ Started Fri Mar 17 16:13:18 MET 1995
+
+ v0.1 (ALPHA, was a user-level program called AudioExcelDSP16.c)
+ - Initial code.
+ v0.2 (ALPHA)
+ - Cleanups.
+ - Integrated with Linux voxware v 2.90-2 kernel sound driver.
+ - SoundBlaster Pro mode configuration.
+ - Microsoft Sound System mode configuration.
+ - MPU-401 mode configuration.
+ v0.3 (ALPHA)
+ - Cleanups.
+ - Rearranged the code to let aedsp16_init_board be more general.
+ - Erased the REALLY_SLOW_IO. We don't need it. Erased the linux/io.h
+ inclusion too. We rely on os.h
+ - Used the to get a variable
+ len string (we are not sure about the len of Copyright string).
+ This works with any SB and compatible.
+ - Added the code to request_region at device init (should go in
+ the main body of voxware).
+ v0.4 (BETA)
+ - Better configure.c patch for aedsp16 configuration (better
+ logic of inclusion of AEDSP16 support)
+ - Modified the conditional compilation to better support more than
+ one sound card of the emulated type (read the NOTES above)
+ - Moved the sb init routine from the attach to the very first
+ probe in sb_card.c
+ - Rearrangements and cleanups
+ - Wiped out some unnecessary code and variables: this is kernel
+ code so it is better save some TEXT and DATA
+ - Fixed the request_region code. We must allocate the aedsp16 (sbpro)
+ I/O ports in any case because they are used to access the DSP
+ configuration registers and we can not allow anyone to get them.
+ v0.5
+ - cleanups on comments
+ - prep for diffs against v3.0-proto-950402
+ v0.6
+ - removed the request_region()s when compiling the MODULE sound.o
+ because we are not allowed (by the actual voxware structure) to
+ release_region()
+ v0.7 (pre ALPHA, not distributed)
+ - started porting this module to kernel 1.3.84. Dummy probe/attach
+ routines.
+ v0.8 (ALPHA)
+ - attached all the init routines.
+ v0.9 (BETA)
+ - Integrated with linux-pre2.0.7
+ - Integrated with configuration scripts.
+ - Cleaned up and beautyfied the code.
+ v0.9.9 (BETA)
+ - Thanks to Piercarlo Grandi: corrected the conditonal compilation code.
+ Now only the code configured is compiled in, with some memory saving.
+ v0.9.10
+ - Integration into the sound/lowlevel/ section of the sound driver.
+ - Re-organized the code.
+ v0.9.11 (not distributed)
+ - Rewritten the init interface-routines to initialize the AEDSP16 in
+ one shot.
+ - More cosmetics.
+ - SC-6600 support.
+ - More soft/hard configuration.
+ v0.9.12
+ - Refined the v0.9.11 code with conditional compilation to distinguish
+ between SC-6000 and SC-6600 code.
+ v1.0.0
+ - Prep for merging with OSS Lite and Linux kernel 2.1.13
+ - Corrected a bug in request/check/release region calls (thanks to the
+ new kernel exception handling).
+ v1.1
+ - Revamped for integration with new modularized sound drivers: to enhance
+ the flexibility of modular version, I have removed all the conditional
+ compilation for SBPRO, MPU and MSS code. Now it is all managed with
+ the ae_config structure.
+ v1.2
+ - Module informations added.
+ - Removed aedsp16_delay_10msec(), now using mdelay(10)
+ - All data and funcs moved to .*.init section.
+ v1.3
+ Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/09/27
+ - got rid of check_region
+
+ Known Problems:
+ - Audio Excel DSP 16 III don't work with this driver.
+
+ Credits:
+ Many thanks to Gerald Britton <gbritton@CapAccess.org>. He helped me a
+ lot in testing the 0.9.11 and 0.9.12 versions of this driver.

+/* ++TeSche: radically changed for new expanding purposes...
+ *
+ * These two routines now deal with copying/expanding/translating the samples
+ * from user space into our buffer at the right frequency. They take care about
+ * how much data there's actually to read, how much buffer space there is and
+ * to convert samples into the right frequency/encoding. They will only work on
+ * complete samples so it may happen they leave some bytes in the input stream
+ * if the user didn't write a multiple of the current sample size. They both
+ * return the number of bytes they've used from both streams so you may detect
+ * such a situation. Luckily all programs should be able to cope with that.
+ *
+ * I think I've optimized anything as far as one can do in plain C, all
+ * variables should fit in registers and the loops are really short. There's
+ * one loop for every possible situation. Writing a more generalized and thus
+ * parameterized loop would only produce slower code. Feel free to optimize
+ * this in assembler if you like. :)
+ *
+ * I think these routines belong here because they're not yet really hardware
+ * independent, especially the fact that the Falcon can play 16bit samples
+ * only in stereo is hardcoded in both of them!
+ *
+ * ++geert: split in even more functions (one per format)

+ * linux/sound/oss/dmasound/dmasound_core.c
+ *
+ *
+ * OSS/Free compatible Atari TT/Falcon and Amiga DMA sound driver for
+ * Linux/m68k
+ * Extended to support Power Macintosh for Linux/ppc by Paul Mackerras
+ *
+ * (c) 1995 by Michael Schlueter & Michael Marte
+ *
+ * Michael Schlueter (michael@duck.syd.de) did the basic structure of the VFS
+ * interface and the u-law to signed byte conversion.
+ *
+ * Michael Marte (marte@informatik.uni-muenchen.de) did the sound queue,
+ * /dev/mixer, /dev/sndstat and complemented the VFS interface. He would like
+ * to thank:
+ * - Michael Schlueter for initial ideas and documentation on the MFP and
+ * the DMA sound hardware.
+ * - Therapy? for their CD 'Troublegum' which really made me rock.
+ *
+ * /dev/sndstat is based on code by Hannu Savolainen, the author of the
+ * VoxWare family of drivers.
+ *
+ * This file is subject to the terms and conditions of the GNU General Public
+ * License. See the file COPYING in the main directory of this archive
+ * for more details.
+ *
+ * History:
+ *
+ * 1995/8/25 First release
+ *
+ * 1995/9/02 Roman Hodek:
+ * - Fixed atari_stram_alloc() call, the timer
+ * programming and several race conditions
+ * 1995/9/14 Roman Hodek:
+ * - After some discussion with Michael Schlueter,
+ * revised the interrupt disabling
+ * - Slightly speeded up U8->S8 translation by using
+ * long operations where possible
+ * - Added 4:3 interpolation for /dev/audio
+ *
+ * 1995/9/20 Torsten Scherer:
+ * - Fixed a bug in sq_write and changed /dev/audio
+ * converting to play at 12517Hz instead of 6258Hz.
+ *
+ * 1995/9/23 Torsten Scherer:
+ * - Changed sq_interrupt() and sq_play() to pre-program
+ * the DMA for another frame while there's still one
+ * running. This allows the IRQ response to be
+ * arbitrarily delayed and playing will still continue.
+ *
+ * 1995/10/14 Guenther Kelleter, Torsten Scherer:
+ * - Better support for Falcon audio (the Falcon doesn't
+ * raise an IRQ at the end of a frame, but at the
+ * beginning instead!). uses 'if (codec_dma)' in lots
+ * of places to simply switch between Falcon and TT
+ * code.
+ *
+ * 1995/11/06 Torsten Scherer:
+ * - Started introducing a hardware abstraction scheme
+ * (may perhaps also serve for Amigas?)
+ * - Can now play samples at almost all frequencies by
+ * means of a more generalized expand routine
+ * - Takes a good deal of care to cut data only at
+ * sample sizes
+ * - Buffer size is now a kernel runtime option
+ * - Implemented fsync() & several minor improvements
+ * Guenther Kelleter:
+ * - Useful hints and bug fixes
+ * - Cross-checked it for Falcons
+ *
+ * 1996/3/9 Geert Uytterhoeven:
+ * - Support added for Amiga, A-law, 16-bit little
+ * endian.
+ * - Unification to drivers/sound/dmasound.c.
+ *
+ * 1996/4/6 Martin Mitchell:
+ * - Updated to 1.3 kernel.
+ *
+ * 1996/6/13 Topi Kanerva:
+ * - Fixed things that were broken (mainly the amiga
+ * 14-bit routines)
+ * - /dev/sndstat shows now the real hardware frequency
+ * - The lowpass filter is disabled by default now
+ *
+ * 1996/9/25 Geert Uytterhoeven:
+ * - Modularization
+ *
+ * 1998/6/10 Andreas Schwab:
+ * - Converted to use sound_core
+ *
+ * 1999/12/28 Richard Zidlicky:
+ * - Added support for Q40
+ *
+ * 2000/2/27 Geert Uytterhoeven:
+ * - Clean up and split the code into 4 parts:
+ * o dmasound_core: machine-independent code
+ * o dmasound_atari: Atari TT and Falcon support
+ * o dmasound_awacs: Apple PowerMac support
+ * o dmasound_paula: Amiga support
+ *
+ * 2000/3/25 Geert Uytterhoeven:
+ * - Integration of dmasound_q40
+ * - Small clean ups
+ *
+ * 2001/01/26 [1.0] Iain Sandoe
+ * - make /dev/sndstat show revision & edition info.
+ * - since dmasound.mach.sq_setup() can fail on pmac
+ * its type has been changed to int and the returns
+ * are checked.
+ * [1.1] - stop missing translations from being called.
+ * 2001/02/08 [1.2] - remove unused translation tables & move machine-
+ * specific tables to low-level.
+ * - return correct info. for SNDCTL_DSP_GETFMTS.
+ * [1.3] - implement SNDCTL_DSP_GETCAPS fully.
+ * [1.4] - make /dev/sndstat text length usage deterministic.
+ * - make /dev/sndstat call to low-level
+ * dmasound.mach.state_info() pass max space to ll driver.
+ * - tidy startup banners and output info.
+ * [1.5] - tidy up a little (removed some unused #defines in
+ * dmasound.h)
+ * - fix up HAS_RECORD conditionalisation.
+ * - add record code in places it is missing...
+ * - change buf-sizes to bytes to allow < 1kb for pmac
+ * if user param entry is < 256 the value is taken to
+ * be in kb > 256 is taken to be in bytes.
+ * - make default buff/frag params conditional on
+ * machine to allow smaller values for pmac.
+ * - made the ioctls, read & write comply with the OSS
+ * rules on setting params.
+ * - added parsing of _setup() params for record.
+ * 2001/04/04 [1.6] - fix bug where sample rates higher than maximum were
+ * being reported as OK.
+ * - fix open() to return -EBUSY as per OSS doc. when
+ * audio is in use - this is independent of O_NOBLOCK.
+ * - fix bug where SNDCTL_DSP_POST was blocking.
+ */
+
+ /* Record capability notes 30/01/2001:
+ * At present these observations apply only to pmac LL driver (the only one
+ * that can do record, at present). However, if other LL drivers for machines
+ * with record are added they may apply.
+ *
+ * The fragment parameters for the record and play channels are separate.
+ * However, if the driver is opened O_RDWR there is no way (in the current OSS
+ * API) to specify their values independently for the record and playback
+ * channels. Since the only common factor between the input & output is the
+ * sample rate (on pmac) it should be possible to open /dev/dspX O_WRONLY and
+ * /dev/dspY O_RDONLY. The input & output channels could then have different
+ * characteristics (other than the first that sets sample rate claiming the
+ * right to set it for ever). As it stands, the format, channels, number of
+ * bits & sample rate are assumed to be common. In the future perhaps these
+ * should be the responsibility of the LL driver - and then if a card really
+ * does not share items between record & playback they can be specified
+ * separately.
+*/
+
+/* Thread-safeness of shared_resources notes: 31/01/2001
+ * If the user opens O_RDWR and then splits record & play between two threads
+ * both of which inherit the fd - and then starts changing things from both
+ * - we will have difficulty telling.
+ *
+ * It's bad application coding - but ...
+ * TODO: think about how to sort this out... without bogging everything down in
+ * semaphores.
+ *
+ * Similarly, the OSS spec says "all changes to parameters must be between
+ * open() and the first read() or write(). - and a bit later on (by
+ * implication) "between SNDCTL_DSP_RESET and the first read() or write() after
+ * it". If the app is multi-threaded and this rule is broken between threads
+ * we will have trouble spotting it - and the fault will be rather obscure :-(
+ *
+ * We will try and put out at least a kmsg if we see it happen... but I think
+ * it will be quite hard to trap it with an -EXXX return... because we can't
+ * see the fault until after the damage is done.

+ *
+ * These two routines now deal with copying/expanding/translating the samples
+ * from user space into our buffer at the right frequency. They take care about
+ * how much data there's actually to read, how much buffer space there is and
+ * to convert samples into the right frequency/encoding. They will only work on
+ * complete samples so it may happen they leave some bytes in the input stream
+ * if the user didn't write a multiple of the current sample size. They both
+ * return the number of bytes they've used from both streams so you may detect
+ * such a situation. Luckily all programs should be able to cope with that.
+ *
+ * I think I've optimized anything as far as one can do in plain C, all
+ * variables should fit in registers and the loops are really short. There's
+ * one loop for every possible situation. Writing a more generalized and thus
+ * parameterized loop would only produce slower code. Feel free to optimize
+ * this in assembler if you like. :)
+ *
+ * I think these routines belong here because they're not yet really hardware
+ * independent, especially the fact that the Falcon can play 16bit samples
+ * only in stereo is hardcoded in both of them!

+ *
+ * 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.

+ * Thomas Sailer ioctl code reworked (vmalloc/vfree removed)
+ * Alan Cox modularisation, clean up.
+ *
+ * 98-02-21: Vladimir Michl <vladimir.michl@upol.cz>
+ * Added mixer device for Beethoven ADSP-16 (master volume,
+ * bass, treble, synth), only for speakers.
+ * Fixed bug in pss_write (exchange parameters)
+ * Fixed config port of SB
+ * Requested two regions for PSS (PSS mixer, PSS config)
+ * Modified pss_download_boot
+ * To probe_pss_mss added test for initialize AD1848
+ * 98-05-28: Vladimir Michl <vladimir.michl@upol.cz>
+ * Fixed computation of mixer volumes
+ * 04-05-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
+ * Added code that allows the user to enable his cdrom and/or
+ * joystick through the module parameters pss_cdrom_port and
+ * pss_enable_joystick. pss_cdrom_port takes a port address as its
+ * argument. pss_enable_joystick takes either a 0 or a non-0 as its
+ * argument.
+ * 04-06-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
+ * Separated some code into new functions for easier reuse.
+ * Cleaned up and streamlined new code. Added code to allow a user
+ * to only use this driver for enabling non-sound components
+ * through the new module parameter pss_no_sound (flag). Added
+ * code that would allow a user to decide whether the driver should
+ * reset the configured hardware settings for the PSS board through
+ * the module parameter pss_keep_settings (flag). This flag will
+ * allow a user to free up resources in use by this card if needbe,
+ * furthermore it allows him to use this driver to just enable the
+ * emulations and then be unloaded as it is no longer needed. Both
+ * new settings are only available to this driver if compiled as a
+ * module. The default settings of all new parameters are set to
+ * load the driver as it did in previous versions.
+ * 04-07-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu>
+ * Added module parameter pss_firmware to allow the user to tell
+ * the driver where the firmware file is located. The default
+ * setting is the previous hardcoded setting "/etc/sound/pss_synth".
+ * 00-03-03: Christoph Hellwig <chhellwig@infradead.org>
+ * Adapted to module_init/module_exit
+ * 11-10-2000: Bartlomiej Zolnierkiewicz <bkz@linux-ide.org>
+ * Added __init to probe_pss(), attach_pss() and probe_pss_mpu()
+ * 02-Jan-2001: Chris Rankin
+ * Specify that this module owns the coprocessor

+ * tabs should be 4 spaces, in vi(m): set tabstop=4
+ *
+ * TODO: consistency speed calculations!!
+ * cleanup!
+ * ????: Did I break MIDI support?
+ *
+ * History:
+ *
+ * Rolf Fokkens (Dec 20 1998): ES188x recording level support on a per
+ * fokkensr@vertis.nl input basis.
+ * (Dec 24 1998): Recognition of ES1788, ES1887, ES1888,
+ * ES1868, ES1869 and ES1878. Could be used for
+ * specific handling in the future. All except
+ * ES1887 and ES1888 and ES688 are handled like
+ * ES1688.
+ * (Dec 27 1998): RECLEV for all (?) ES1688+ chips. ES188x now
+ * have the "Dec 20" support + RECLEV
+ * (Jan 2 1999): Preparation for Full Duplex. This means
+ * Audio 2 is now used for playback when dma16
+ * is specified. The next step would be to use
+ * Audio 1 and Audio 2 at the same time.
+ * (Jan 9 1999): Put all ESS stuff into sb_ess.[ch], this
+ * includes both the ESS stuff that has been in
+ * sb_*[ch] before I touched it and the ESS support
+ * I added later
+ * (Jan 23 1999): Full Duplex seems to work. I wrote a small
+ * test proggy which works OK. Haven't found
+ * any applications to test it though. So why did
+ * I bother to create it anyway?? :) Just for
+ * fun.
+ * (May 2 1999): I tried to be too smart by "introducing"
+ * ess_calc_best_speed (). The idea was that two
+ * dividers could be used to setup a samplerate,
+ * ess_calc_best_speed () would choose the best.
+ * This works for playback, but results in
+ * recording problems for high samplerates. I
+ * fixed this by removing ess_calc_best_speed ()
+ * and just doing what the documentation says.
+ * Andy Sloane (Jun 4 1999): Stole some code from ALSA to fix the playback
+ * andy@guildsoftware.com speed on ES1869, ES1879, ES1887, and ES1888.
+ * 1879's were previously ignored by this driver;
+ * added (untested) support for those.
+ * Cvetan Ivanov (Oct 27 1999): Fixed ess_dsp_init to call ess_set_dma_hw for
+ * zezo@inet.bg _ALL_ ESS models, not only ES1887
+ *
+ * This files contains ESS chip specifics. It's based on the existing ESS
+ * handling as it resided in sb_common.c, sb_mixer.c and sb_audio.c. This
+ * file adds features like:
+ * - Chip Identification (as shown in /proc/sound)
+ * - RECLEV support for ES1688 and later
+ * - 6 bits playback level support chips later than ES1688
+ * - Recording level support on a per-device basis for ES1887
+ * - Full-Duplex for ES1887
+ *
+ * Full duplex is enabled by specifying dma16. While the normal dma must
+ * be one of 0, 1 or 3, dma16 can be one of 0, 1, 3 or 5. DMA 5 is a 16 bit
+ * DMA channel, while the others are 8 bit..
+ *
+ * ESS detection isn't full proof (yet). If it fails an additional module
+ * parameter esstype can be specified to be one of the following:
+ * -1, 0, 688, 1688, 1868, 1869, 1788, 1887, 1888
+ * -1 means: mimic 2.0 behaviour,
+ * 0 means: auto detect.
+ * others: explicitly specify chip
+ * -1 is default, cause auto detect still doesn't work.
+ */
+
+/*
+ * About the documentation
+ *
+ * I don't know if the chips all are OK, but the documentation is buggy. 'cause
+ * I don't have all the cips myself, there's a lot I cannot verify. I'll try to
+ * keep track of my latest insights about his here. If you have additional info,
+ * please enlighten me (fokkensr@vertis.nl)!
+ *
+ * I had the impression that ES1688 also has 6 bit master volume control. The
+ * documentation about ES1888 (rev C, october '95) claims that ES1888 has
+ * the following features ES1688 doesn't have:
+ * - 6 bit master volume
+ * - Full Duplex
+ * So ES1688 apparently doesn't have 6 bit master volume control, but the
+ * ES1688 does have RECLEV control. Makes me wonder: does ES688 have it too?
+ * Without RECLEV ES688 won't be much fun I guess.
+ *
+ * From the ES1888 (rev C, october '95) documentation I got the impression
+ * that registers 0x68 to 0x6e don't exist which means: no recording volume
+ * controls. To my surprise the ES888 documentation (1/14/96) claims that
+ * ES888 does have these record mixer registers, but that ES1888 doesn't have
+ * 0x69 and 0x6b. So the rest should be there.
+ *
+ * I'm trying to get ES1887 Full Duplex. Audio 2 is playback only, while Audio 2
+ * is both record and playback. I think I should use Audio 2 for all playback.
+ *
+ * The documentation is an adventure: it's close but not fully accurate. I
+ * found out that after a reset some registers are *NOT* reset, though the
+ * docs say the would be. Interesting ones are 0x7f, 0x7d and 0x7a. They are
+ * related to the Audio 2 channel. I also was surprised about the consequences
+ * of writing 0x00 to 0x7f (which should be done by reset): The ES1887 moves
+ * into ES1888 mode. This means that it claims IRQ 11, which happens to be my
+ * ISDN adapter. Needless to say it no longer worked. I now understand why
+ * after rebooting 0x7f already was 0x05, the value of my choice: the BIOS
+ * did it.
+ *
+ * Oh, and this is another trap: in ES1887 docs mixer register 0x70 is
+ * described as if it's exactly the same as register 0xa1. This is *NOT* true.
+ * The description of 0x70 in ES1869 docs is accurate however.
+ * Well, the assumption about ES1869 was wrong: register 0x70 is very much
+ * like register 0xa1, except that bit 7 is always 1, whatever you want
+ * it to be.
+ *
+ * When using audio 2 mixer register 0x72 seems te be meaningless. Only 0xa2
+ * has effect.
+ *
+ * Software reset not being able to reset all registers is great! Especially
+ * the fact that register 0x78 isn't reset is great when you wanna change back
+ * to single dma operation (simplex): audio 2 is still operational, and uses
+ * the same dma as audio 1: your ess changes into a funny echo machine.
+ *
+ * Received the news that ES1688 is detected as a ES1788. Did some thinking:
+ * the ES1887 detection scheme suggests in step 2 to try if bit 3 of register
+ * 0x64 can be changed. This is inaccurate, first I inverted the * check: "If
+ * can be modified, it's a 1688", which lead to a correct detection
+ * of my ES1887. It resulted however in bad detection of 1688 (reported by mail)
+ * and 1868 (if no PnP detection first): they result in a 1788 being detected.
+ * I don't have docs on 1688, but I do have docs on 1868: The documentation is
+ * probably inaccurate in the fact that I should check bit 2, not bit 3. This
+ * is what I do now.
+ */
+
+/*
+ * About recognition of ESS chips
+ *
+ * The distinction of ES688, ES1688, ES1788, ES1887 and ES1888 is described in
+ * a (preliminary ??) datasheet on ES1887. Its aim is to identify ES1887, but
+ * during detection the text claims that "this chip may be ..." when a step
+ * fails. This scheme is used to distinct between the above chips.
+ * It appears however that some PnP chips like ES1868 are recognized as ES1788
+ * by the ES1887 detection scheme. These PnP chips can be detected in another
+ * way however: ES1868, ES1869 and ES1878 can be recognized (full proof I think)
+ * by repeatedly reading mixer register 0x40. This is done by ess_identify in
+ * sb_common.c.
+ * This results in the following detection steps:
+ * - distinct between ES688 and ES1688+ (as always done in this driver)
+ * if ES688 we're ready
+ * - try to detect ES1868, ES1869 or ES1878
+ * if successful we're ready
+ * - try to detect ES1888, ES1887 or ES1788
+ * if successful we're ready
+ * - Dunno. Must be 1688. Will do in general
+ *
+ * About RECLEV support:
+ *
+ * The existing ES1688 support didn't take care of the ES1688+ recording
+ * levels very well. Whenever a device was selected (recmask) for recording
+ * its recording level was loud, and it couldn't be changed. The fact that
+ * internal register 0xb4 could take care of RECLEV, didn't work meaning until
+ * its value was restored every time the chip was reset; this reset the
+ * value of 0xb4 too. I guess that's what 4front also had (have?) trouble with.
+ *
+ * About ES1887 support:
+ *
+ * The ES1887 has separate registers to control the recording levels, for all
+ * inputs. The ES1887 specific software makes these levels the same as their
+ * corresponding playback levels, unless recmask says they aren't recorded. In
+ * the latter case the recording volumes are 0.
+ * Now recording levels of inputs can be controlled, by changing the playback
+ * levels. Furthermore several devices can be recorded together (which is not
+ * possible with the ES1688).
+ * Besides the separate recording level control for each input, the common
+ * recording level can also be controlled by RECLEV as described above.
+ *
+ * Not only ES1887 have this recording mixer. I know the following from the
+ * documentation:
+ * ES688 no
+ * ES1688 no
+ * ES1868 no
+ * ES1869 yes
+ * ES1878 no
+ * ES1879 yes
+ * ES1888 no/yes Contradicting documentation; most recent: yes
+ * ES1946 yes This is a PCI chip; not handled by this driver

+*
+* Modification History
+* 08/20/00 trw - silence and no stopping DAC until release
+* 08/23/00 trw - added CS_DBG statements, fix interrupt hang issue on DAC stop.
+* 09/18/00 trw - added 16bit only record with conversion
+* 09/24/00 trw - added Enhanced Full duplex (separate simultaneous
+* capture/playback rates)
+* 10/03/00 trw - fixed mmap (fixed GRECORD and the XMMS mmap test plugin
+* libOSSm.so)
+* 10/11/00 trw - modified for 2.4.0-test9 kernel enhancements (NR_MAP removal)
+* 11/03/00 trw - fixed interrupt loss/stutter, added debug.
+* 11/10/00 bkz - added __devinit to cs4297a_hw_init()
+* 11/10/00 trw - fixed SMP and capture spinlock hang.
+* 12/04/00 trw - cleaned up CSDEBUG flags and added "defaultorder" moduleparm.
+* 12/05/00 trw - fixed polling (myth2), and added underrun swptr fix.
+* 12/08/00 trw - added PM support.
+* 12/14/00 trw - added wrapper code, builds under 2.4.0, 2.2.17-20, 2.2.17-8
+* (RH/Dell base), 2.2.18, 2.2.12. cleaned up code mods by ident.
+* 12/19/00 trw - added PM support for 2.2 base (apm_callback). other PM cleanup.
+* 12/21/00 trw - added fractional "defaultorder" inputs. if >100 then use
+* defaultorder-100 as power of 2 for the buffer size. example:
+* 106 = 2^(106-100) = 2^6 = 64 bytes for the buffer size.
