Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+
+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.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ * <pellicci@home.com>. Special thanks to both him and miro for
+ * providing the ACI specification.
+ *
+ * The main function of the ACI is to control the mixer and to get a
+ * product identification. On the PCM20, ACI also controls the radio
+ * tuner on this card, this is supported in the Video for Linux
+ * miropcm20 driver.
+ * -
+ * This is a fullfeatured implementation. Unsupported features
+ * are bugs... (:
+ *
+ * It is not longer necessary to load the mad16 module first. The
+ * user is currently responsible to set the mad16 mixer correctly.
+ *
+ * To toggle the solo mode for full duplex operation just use the OSS
+ * record switch for the pcm ('wave') controller. Robert

+ * Initialize CS4231A mixer, make ACI first mixer,
+ * use new private mixer API for solo mode.
+ * 1998-08-18 Ruurd Reitsma <R.A.Reitsma@wbmt.tudelft.nl>
+ * Small modification to export ACI functions and

+ * 2000-06-20 Robert Siemer <Robert.Siemer@gmx.de>
+ * Don't initialize the CS4231A mixer anymore, so the code is

+ * 2000-08-26 Robert Siemer
+ * Clean up and rewrite for 2.4.x. Maybe it's SMP safe now... (:
+ * ioctl bugfix, and integration of solo-mode into OSS-API,

+ * AD1816 lowlevel sound driver for Linux 2.6.0 and above
+ *
+ * Copyright (C) 1998-2003 by Thorsten Knabe <linux@thorsten-knabe.de>
+ *
+ * Based on the CS4232/AD1848 driver Copyright (C) by Hannu Savolainen 1993-1996
+ *
+ *
+ * version: 1.5
+ * status: beta
+ * date: 2003/07/15
+ *
+ * Changes:
+ * Oleg Drokin: Some cleanup of load/unload functions. 1998/11/24
+ *
+ * Thorsten Knabe: attach and unload rewritten,
+ * some argument checks added 1998/11/30
+ *
+ * Thorsten Knabe: Buggy isa bridge workaround added 1999/01/16
+ *
+ * David Moews/Thorsten Knabe: Introduced options
+ * parameter. Added slightly modified patch from
+ * David Moews to disable dsp audio sources by setting
+ * bit 0 of options parameter. This seems to be
+ * required by some Aztech/Newcom SC-16 cards. 1999/04/18
+ *
+ * Christoph Hellwig: Adapted to module_init/module_exit. 2000/03/03
+ *
+ * Christoph Hellwig: Added isapnp support 2000/03/15
+ *
+ * Arnaldo Carvalho de Melo: get rid of check_region 2001/10/07
+ *
+ * Thorsten Knabe: Compiling with CONFIG_PNP enabled
+ * works again. It is now possible to use more than one
+ * AD1816 sound card. Sample rate now may be changed during
+ * playback/capture. printk() uses log levels everywhere.
+ * SMP fixes. DMA handling fixes.
+ * Other minor code cleanup. 2003/07/15

+ *
+ * The low level driver for the AD1848/CS4248 codec chip which
+ * is used for example in the MS Sound System.
+ *
+ * The CS4231 which is used in the GUS MAX and some other cards is
+ * upwards compatible with AD1848 and this driver is able to drive it.
+ *
+ * CS4231A and AD1845 are upward compatible with CS4231. However
+ * the new features of these chips are different.
+ *
+ * CS4232 is a PnP audio chip which contains a CS4231A (and SB, MPU).
+ * CS4232A is an improved version of CS4232.

+ * general sleep/wakeup clean up.
+ * Alan Cox : reformatted. Fixed SMP bugs. Moved to kernel alloc/free
+ * of irqs. Use dev_id.
+ * Christoph Hellwig : adapted to module_init/module_exit
+ * Aki Laukkanen : added power management support
+ * Arnaldo C. de Melo : added missing restore_flags in ad1848_resume
+ * Miguel Freitas : added ISA PnP support
+ * Alan Cox : Added CS4236->4239 identification
+ * Daniel T. Cobra : Alernate config/mixer for later chips
+ * Alan Cox : Merged chip idents and config code
+ *
+ * TODO
+ * APM save restore assist code on IBM thinkpad
+ *
+ * Status:

+<jsm> Also, when changing the sample rate on the codec you need to power it down and re power it up for the change to take effect!

+
+ 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 an 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.

+ * ALi 5455 theory of operation
+ *
+ * The chipset provides three DMA channels that talk to an AC97
+ * CODEC (AC97 is a digital/analog mixer standard). At its simplest
+ * you get 48Khz audio with basic volume and mixer controls. At the
+ * best you get rate adaption in the codec. We set the card up so
+ * that we never take completion interrupts but instead keep the card
+ * chasing its tail around a ring buffer. This is needed for mmap
+ * mode audio and happens to work rather well for non-mmap modes too.
+ *
+ * The board has one output channel for PCM audio (supported) and
+ * a stereo line in and mono microphone input. Again these are normally
+ * locked to 48Khz only. Right now recording is not finished.
+ *
+ * There is no midi support, no synth support. Use timidity. To get
+ * esd working you need to use esd -r 48000 as it won't probe 48KHz
+ * by default. mpg123 can't handle 48Khz only audio so use xmms.
+ *
+ * If you need to force a specific rate set the clocking= option
+ *

+ * 06.27.2001 Initial version
+ * 03.20.2002 Added mutex locks around read/write methods, to prevent
+ * simultaneous access on SMP or preemptible kernels. Also
+ * removed the counter/pointer fragment aligning at the end
+ * of read/write methods [stevel].
+ * 03.21.2002 Add support for coherent DMA on the audio read/write DMA
+ * channels [stevel].

+ * Special thanks to David C. Niemi, Jan Pfeifer
+ *
+ *
+ * Module command line parameters:
+ * none so far
+ *
+ *
+ * Supported devices:
+ * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
+ * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
+ * /dev/midi simple MIDI UART interface, no ioctl
+ *
+ * The card has both an FM and a Wavetable synth, but I have to figure
+ * out first how to drive them...
+ *
+ * Revision history
+ * 06.05.98 0.1 Initial release
+ * 10.05.98 0.2 Fixed many bugs, esp. ADC rate calculation
+ * First stab at a simple midi interface (no bells&whistles)
+ * 13.05.98 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of
+ * set_dac_rate in the FMODE_WRITE case in cm_open
+ * Fix hwptr out of bounds (now mpg123 works)
+ * 14.05.98 0.4 Don't allow excessive interrupt rates
+ * 08.06.98 0.5 First release using Alan Cox' soundcore instead of miscdevice
+ * 03.08.98 0.6 Do not include modversions.h
+ * Now mixer behaviour can basically be selected between
+ * "OSS documented" and "OSS actual" behaviour
+ * 31.08.98 0.7 Fix realplayer problems - dac.count issues
+ * 10.12.98 0.8 Fix drain_dac trying to wait on not yet initialized DMA
+ * 16.12.98 0.9 Fix a few f_file & FMODE_ bugs
+ * 06.01.99 0.10 remove the silly SA_INTERRUPT flag.
+ * hopefully killed the egcs section type conflict
+ * 12.03.99 0.11 cinfo.blocks should be reset after GETxPTR ioctl.
+ * reported by Johan Maes <joma@telindus.be>
+ * 22.03.99 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK
+ * read/write cannot be executed
+ * 18.08.99 1.5 Only deallocate DMA buffer when unloading.
+ * 02.09.99 1.6 Enable SPDIF LOOP
+ * Change the mixer read back
+ * 21.09.99 2.33 Use RCS version as driver version.
+ * Add support for modem, S/PDIF loop and 4 channels.
+ * (8738 only)
+ * Fix bug cause x11amp cannot play.
+ *
+ * Fixes:
+ * Arnaldo Carvalho de Melo <acme@conectiva.com.br>
+ * 18/05/2001 - .bss nitpicks, fix a bug in set_dac_channels where it
+ * was calling prog_dmabuf with s->lock held, call missing
+ * unlock_kernel in cm_midi_release
+ * 08/10/2001 - use set_current_state in some more places
+ *
+ * Carlos Eduardo Gorges <carlos@techlinux.com.br>
+ * Fri May 25 2001
+ * - SMP support ( spin[un]lock* revision )
+ * - speaker mixer support
+ * Mon Aug 13 2001
+ * - optimizations and cleanups
+ *
+ * 03/01/2003 - open_mode fixes from Georg Acher <acher@in.tum.de>
+ * Simon Braunschmidt <brasimon@web.de>
+ * Sat Jan 31 2004
+ * - provide support for opl3 FM by releasing IO range after initialization
+ *
+ * ChenLi Tien <cltien@cmedia.com.tw>
+ * Mar 9 2004
+ * - Fix S/PDIF out if spdif_loop enabled
+ * - Load opl3 driver if enabled (fmio in proper range)
+ * - Load mpu401 if enabled (mpuio in proper range)
+ * Apr 5 2004
+ * - Fix DUAL_DAC dma synchronization bug
+ * - Check exist FM/MPU401 I/O before activate.
+ * - Add AFTM_S16_BE format support, so MPlayer/Xine can play AC3/mutlichannel
+ * on Mac
+ * - Change to support kernel 2.6 so only small patch needed
+ * - All parameters default to 0
+ * - Add spdif_out to send PCM through S/PDIF out jack
+ * - Add hw_copy to get 4-spaker output for general PCM/analog output
+ *
+ * Stefan Thater <stefan.thaeter@gmx.de>
+ * Apr 5 2004
+ * - Fix mute single channel for CD/Line-in/AUX-in

+ * cs4232.c
+ *
+ * The low level driver for Crystal CS4232 based cards. The CS4232 is
+ * a PnP compatible chip which contains a CS4231A codec, SB emulation,
+ * a MPU401 compatible MIDI port, joystick and synthesizer and IDE CD-ROM
+ * interfaces. This is just a temporary driver until full PnP support
+ * gets implemented. Just the WSS codec, FM synth and the MIDI ports are
+ * supported. Other interfaces are left uninitialized.
+ *
+ * ifdef ...WAVEFRONT...
+ *
+ * Support is provided for initializing the WaveFront synth
+ * interface as well, which is logical device #4. Note that if
+ * you have a Tropez+ card, you probably don't need to setup
+ * the CS4232-supported MIDI interface, since it corresponds to
+ * the internal 26-pin header that's hard to access. Using this
+ * requires an additional IRQ, a resource none too plentiful in
+ * this environment. Just don't set module parameters mpuio and
+ * mpuirq, and the MIDI port will be left uninitialized. You can
+ * still use the ICS2115 hosted MIDI interface which corresponds
+ * to the 9-pin D connector on the back of the card.
+ *
+ * endif ...WAVEFRONT...
+ *
+ * Supported chips are:
+ * CS4232
+ * CS4236
+ * CS4236B
+ *
+ * Note: You will need a PnP config setup to initialise some CS4232 boards
+ * anyway.
+ *
+ * Changes
+ * John Rood Added Bose Sound System Support.
+ * Toshio Spoor
+ * Alan Cox Modularisation, Basic cleanups.
+ * Paul Barton-Davis Separated MPU configuration, added
+ * Tropez+ (WaveFront) support
+ * Christoph Hellwig Adapted to module_init/module_exit,
+ * simple cleanups
+ * Arnaldo C. de Melo got rid of attach_uart401
+ * Bartlomiej Zolnierkiewicz
+ * Added some __init/__initdata/__exit
+ * Marcus Meissner Added ISA PnP support.

+* /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
+* /dev/midi simple MIDI UART interface, no ioctl
+*
+* 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 cs4281_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.

+ *
+ * Changes:
+ * 20000909-nf Changed cs_read, cs_write and drain_dac
+ * 20001025-tw Separate Playback/Capture structs and buffers.
+ * Added Scatter/Gather support for Playback.
+ * Added Capture.
+ * 20001027-nf Port to kernel 2.4.0-test9, some clean-ups
+ * Start of powermanagement support (CS46XX_PM).
+ * 20001128-tw Add module parm for default buffer order.
+ * added DMA_GFP flag to kmalloc dma buffer allocs.
+ * backfill silence to eliminate stuttering on
+ * underruns.
+ * 20001201-tw add resyncing of swptr on underruns.
+ * 20001205-tw-nf fixed GETOSPACE ioctl() after open()
+ * 20010113-tw patch from Hans Grobler general cleanup.
+ * 20010117-tw 2.4.0 pci cleanup, wrapper code for 2.2.16-2.4.0
+ * 20010118-tw basic PM support for 2.2.16+ and 2.4.0/2.4.2.
+ * 20010228-dh patch from David Huggins - cs_update_ptr recursion.
+ * 20010409-tw add hercules game theatre XP amp code.
+ * 20010420-tw cleanup powerdown/up code.
+ * 20010521-tw eliminate pops, and fixes for powerdown.
+ * 20010525-tw added fixes for thinkpads with powerdown logic.
+ * 20010723-sh patch from Horms (Simon Horman) -
+ * SOUND_PCM_READ_BITS returns bits as set in driver
+ * rather than a logical or of the possible values.
+ * Various ioctls handle the case where the device
+ * is open for reading or writing but not both better.
+ *
+ * Status:
+ * Playback/Capture supported from 8k-48k.
+ * 16Bit Signed LE & 8Bit Unsigned, with Mono or Stereo supported.
+ *
+ * APM/PM - 2.2.x APM is enabled and functioning fine. APM can also
+ * be enabled for 2.4.x by modifying the CS46XX_ACPI_SUPPORT macro
+ * definition.
+ *
+ * Hercules Game Theatre XP - the EGPIO2 pin controls the external Amp,
+ * so, use the drain/polarity to enable.
+ * hercules_egpio_disable set to 1, will force a 0 to EGPIODR.
+ *
+ * VTB Santa Cruz - the GPIO7/GPIO8 on the Secondary Codec control
+ * the external amplifier for the "back" speakers, since we do not
+ * support the secondary codec then this external amp is also not
+ * turned on.

+/* ++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_awacs.c
+ *
+ * PowerMac `AWACS' and `Burgundy' DMA Sound Driver
+ * with some limited support for DACA & Tumbler
+ *
+ * See linux/sound/oss/dmasound/dmasound_core.c for copyright and
+ * history prior to 2001/01/26.
+ *
+ * 26/01/2001 ed 0.1 Iain Sandoe
+ * - added version info.
+ * - moved dbdma command buffer allocation to PMacXXXSqSetup()
+ * - fixed up beep dbdma cmd buffers
+ *
+ * 08/02/2001 [0.2]
+ * - make SNDCTL_DSP_GETFMTS return the correct info for the h/w
+ * - move soft format translations to a separate file
+ * - [0.3] make SNDCTL_DSP_GETCAPS return correct info.
+ * - [0.4] more informative machine name strings.
+ * - [0.5]
+ * - record changes.
+ * - made the default_hard/soft entries.
+ * 04/04/2001 [0.6]
+ * - minor correction to bit assignments in awacs_defs.h
+ * - incorporate mixer changes from 2.2.x back-port.
+ * - take out passthru as a rec input (it isn't).
+ * - make Input Gain slider work the 'right way up'.
+ * - try to make the mixer sliders more logical - so now the
+ * input selectors are just two-state (>50% == ON) and the
+ * Input Gain slider handles the rest of the gain issues.
+ * - try to pick slider representations that most closely match
+ * the actual use - e.g. IGain for input gain...
+ * - first stab at over/under-run detection.
+ * - minor cosmetic changes to IRQ identification.
+ * - fix bug where rates > max would be reported as supported.
+ * - first stab at over/under-run detection.
+ * - make use of i2c for mixer settings conditional on perch
+ * rather than cuda (some machines without perch have cuda).
+ * - fix bug where TX stops when dbdma status comes up "DEAD"
+ * so far only reported on PowerComputing clones ... but.
+ * - put in AWACS/Screamer register write timeouts.
+ * - part way to partitioning the init() stuff
+ * - first pass at 'tumbler' stuff (not support - just an attempt
+ * to allow the driver to load on new G4s).
+ * 01/02/2002 [0.7] - BenH
+ * - all sort of minor bits went in since the latest update, I
+ * bumped the version number for that reason
+ *
+ * 07/26/2002 [0.8] - BenH
+ * - More minor bits since last changelog (I should be more careful
+ * with those)
+ * - Support for snapper & better tumbler integration by Toby Sargeant
+ * - Headphone detect for scremer by Julien Blache
+ * - More tumbler fixed by Andreas Schwab
+ * 11/29/2003 [0.8.1] - Renzo Davoli (King Enzo)
+ * - Support for Snapper line in
+ * - snapper input resampling (for rates < 44100)
+ * - software line gain control
+ */
+
+/* GENERAL FIXME/TODO: check that the assumptions about what is written to

+ * 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.

+/* ++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.
+ *

+ To over come this, samples are copied into the tram and a special dsp patch copies
+ the samples out and generates interrupts when a block has finnished playing.

+
+ Creative fixed the sample rate convert problem in emu10k1 rev 7 and higher
+ (including the emu10k2 (audigy)). This allows us to use the regular, and much simpler
+ playback method.
+
+
+ In both methods, dsp code is used to mux audio and passthrough. This ensures that the spdif
+ doesn't receive audio and pasthrough data at the same time. The spdif flag SPCS_NOTAUDIODATA

+ *
+ * Module command line parameters:
+ * lineout if 1 the LINE jack is used as an output instead of an input.
+ * LINE then contains the unmixed dsp output. This can be used
+ * to make the card a four channel one: use dsp to output two
+ * channels to LINE and dac to output the other two channels to
+ * SPKR. Set the mixer to only output synth to SPKR.
+ * micbias sets the +5V bias to the mic if using an electretmic.
+ *
+ *
+ * Note: sync mode is not yet supported (i.e. running dsp and dac from the same
+ * clock source)
+ *
+ * Supported devices:
+ * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
+ * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
+ * /dev/dsp1 additional DAC, like /dev/dsp, but output only,
+ * only 5512, 11025, 22050 and 44100 samples/s,
+ * outputs to mixer "SYNTH" setting
+ * /dev/midi simple MIDI UART interface, no ioctl
+ *
+ * NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
+ * to be done in software. That is what /dev/dac is for. By now (Q2 1998)
+ * there are several MIDI to PCM (WAV) packages, one of them is timidity.
+ *
+ * Revision history
+ * 26.03.1998 0.1 Initial release
+ * 31.03.1998 0.2 Fix bug in GETOSPACE
+ * 04.04.1998 0.3 Make it work (again) under 2.0.33
+ * Fix mixer write operation not returning the actual
+ * settings
+ * 05.04.1998 0.4 First attempt at using the new PCI stuff
+ * 29.04.1998 0.5 Fix hang when ^C is pressed on amp
+ * 07.05.1998 0.6 Don't double lock around stop_*() in *_release()
+ * 10.05.1998 0.7 First stab at a simple midi interface (no bells&whistles)
+ * 14.05.1998 0.8 Don't allow excessive interrupt rates
+ * 08.06.1998 0.9 First release using Alan Cox' soundcore instead of
+ * miscdevice
+ * 05.07.1998 0.10 Fixed the driver to correctly maintin OSS style volume
+ * settings (not sure if this should be standard)
+ * Fixed many references: f_flags should be f_mode
+ * -- Gerald Britton <gbritton@mit.edu>
+ * 03.08.1998 0.11 Now mixer behaviour can basically be selected between
+ * "OSS documented" and "OSS actual" behaviour
+ * Fixed mixer table thanks to Hakan.Lennestal@lu.erisoft.se
+ * On module startup, set DAC2 to 11kSPS instead of 5.5kSPS,
+ * as it produces an annoying ssssh in the lower sampling rate
+ * Do not include modversions.h
+ * 22.08.1998 0.12 Mixer registers actually have 5 instead of 4 bits
+ * pointed out by Itai Nahshon
+ * 31.08.1998 0.13 Fix realplayer problems - dac.count issues
+ * 08.10.1998 0.14 Joystick support fixed
+ * -- Oliver Neukum <c188@org.chemie.uni-muenchen.de>
+ * 10.12.1998 0.15 Fix drain_dac trying to wait on not yet initialized DMA
+ * 16.12.1998 0.16 Don't wake up app until there are fragsize bytes to read/write
+ * 06.01.1999 0.17 remove the silly SA_INTERRUPT flag.
+ * hopefully killed the egcs section type conflict
+ * 12.03.1999 0.18 cinfo.blocks should be reset after GETxPTR ioctl.
+ * reported by Johan Maes <joma@telindus.be>
+ * 22.03.1999 0.19 return EAGAIN instead of EBUSY when O_NONBLOCK
+ * read/write cannot be executed
+ * 07.04.1999 0.20 implemented the following ioctl's: SOUND_PCM_READ_RATE,
+ * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
+ * Alpha fixes reported by Peter Jones <pjones@redhat.com>
+ * Note: joystick address handling might still be wrong on archs
+ * other than i386
+ * 10.05.1999 0.21 Added support for an electret mic for SB PCI64
+ * to the Linux kernel sound driver. This mod also straighten
+ * out the question marks around the mic impedance setting
+ * (micz). From Kim.Berts@fisub.mail.abb.com
+ * 11.05.1999 0.22 Implemented the IMIX call to mute recording monitor.
+ * Guenter Geiger <geiger@epy.co.at>
+ * 15.06.1999 0.23 Fix bad allocation bug.
+ * Thanks to Deti Fliegl <fliegl@in.tum.de>
+ * 28.06.1999 0.24 Add pci_set_master
+ * 02.08.1999 0.25 Added workaround for the "phantom write" bug first
+ * documented by Dave Sharpless from Anchor Games
+ * 03.08.1999 0.26 adapt to Linus' new __setup/__initcall
+ * added kernel command line option "es1370=joystick[,lineout[,micbias]]"
+ * removed CONFIG_SOUND_ES1370_JOYPORT_BOOT kludge
+ * 12.08.1999 0.27 module_init/__setup fixes
+ * 19.08.1999 0.28 SOUND_MIXER_IMIX fixes, reported by Gianluca <gialluca@mail.tiscalinet.it>
+ * 31.08.1999 0.29 add spin_lock_init
+ * replaced current->state = x with set_current_state(x)
+ * 03.09.1999 0.30 change read semantics for MIDI to match
+ * OSS more closely; remove possible wakeup race
+ * 28.10.1999 0.31 More waitqueue races fixed
+ * 08.01.2000 0.32 Prevent some ioctl's from returning bad count values on underrun/overrun;
+ * Tim Janik's BSE (Bedevilled Sound Engine) found this
+ * 07.02.2000 0.33 Use pci_alloc_consistent and pci_register_driver
+ * 21.11.2000 0.34 Initialize dma buffers in poll, otherwise poll may return a bogus mask
+ * 12.12.2000 0.35 More dma buffer initializations, patch from
+ * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
+ * 07.01.2001 0.36 Timeout change in wrcodec as requested by Frank Klemm <pfk@fuchs.offl.uni-jena.de>
+ * 31.01.2001 0.37 Register/Unregister gameport
+ * Fix SETTRIGGER non OSS API conformity
+ * 03.01.2003 0.38 open_mode fixes from Georg Acher <acher@in.tum.de>
+ *
+ * some important things missing in Ensoniq documentation:
+ *
+ * Experimental PCLKDIV results: play the same waveforms on both DAC1 and DAC2
+ * and vary PCLKDIV to obtain zero beat.
+ * 5512sps: 254
+ * 44100sps: 30
+ * seems to be fs = 1411200/(PCLKDIV+2)
+ *
+ * should find out when curr_sample_ct is cleared and
+ * where exactly the CCB fetches data
+ *
+ * The card uses a 22.5792 MHz crystal.
+ * The LINEIN jack may be converted to an AOUT jack by
+ * setting pin 47 (XCTL0) of the ES1370 to high.
+ * Pin 48 (XCTL1) of the ES1370 sets the +5V bias for an electretmic
+ *

+ * Special thanks to Ensoniq
+ *
+ * Supported devices:
+ * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
+ * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
+ * /dev/dsp1 additional DAC, like /dev/dsp, but outputs to mixer "SYNTH" setting
+ * /dev/midi simple MIDI UART interface, no ioctl
+ *
+ * NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
+ * to be done in software. That is what /dev/dac is for. By now (Q2 1998)
+ * there are several MIDI to PCM (WAV) packages, one of them is timidity.
+ *
+ * Revision history
+ * 04.06.1998 0.1 Initial release
+ * Mixer stuff should be overhauled; especially optional AC97 mixer bits
+ * should be detected. This results in strange behaviour of some mixer
+ * settings, like master volume and mic.
+ * 08.06.1998 0.2 First release using Alan Cox' soundcore instead of miscdevice
+ * 03.08.1998 0.3 Do not include modversions.h
+ * Now mixer behaviour can basically be selected between
+ * "OSS documented" and "OSS actual" behaviour
+ * 31.08.1998 0.4 Fix realplayer problems - dac.count issues
+ * 27.10.1998 0.5 Fix joystick support
+ * -- Oliver Neukum (c188@org.chemie.uni-muenchen.de)
+ * 10.12.1998 0.6 Fix drain_dac trying to wait on not yet initialized DMA
+ * 23.12.1998 0.7 Fix a few f_file & FMODE_ bugs
+ * Don't wake up app until there are fragsize bytes to read/write
+ * 06.01.1999 0.8 remove the silly SA_INTERRUPT flag.
+ * hopefully killed the egcs section type conflict
+ * 12.03.1999 0.9 cinfo.blocks should be reset after GETxPTR ioctl.
+ * reported by Johan Maes <joma@telindus.be>
+ * 22.03.1999 0.10 return EAGAIN instead of EBUSY when O_NONBLOCK
+ * read/write cannot be executed
+ * 07.04.1999 0.11 implemented the following ioctl's: SOUND_PCM_READ_RATE,
+ * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
+ * Alpha fixes reported by Peter Jones <pjones@redhat.com>
+ * Another Alpha fix (wait_src_ready in init routine)
+ * reported by "Ivan N. Kokshaysky" <ink@jurassic.park.msu.ru>
+ * Note: joystick address handling might still be wrong on archs
+ * other than i386
+ * 15.06.1999 0.12 Fix bad allocation bug.
+ * Thanks to Deti Fliegl <fliegl@in.tum.de>
+ * 28.06.1999 0.13 Add pci_set_master
+ * 03.08.1999 0.14 adapt to Linus' new __setup/__initcall
+ * added kernel command line option "es1371=joystickaddr"
+ * removed CONFIG_SOUND_ES1371_JOYPORT_BOOT kludge
+ * 10.08.1999 0.15 (Re)added S/PDIF module option for cards revision >= 4.
+ * Initial version by Dave Platt <dplatt@snulbug.mtview.ca.us>.
+ * module_init/__setup fixes
+ * 08.16.1999 0.16 Joe Cotellese <joec@ensoniq.com>
+ * Added detection for ES1371 revision ID so that we can
+ * detect the ES1373 and later parts.
+ * added AC97 #defines for readability
+ * added a /proc file system for dumping hardware state
+ * updated SRC and CODEC w/r functions to accommodate bugs
+ * in some versions of the ES137x chips.
+ * 31.08.1999 0.17 add spin_lock_init
+ * replaced current->state = x with set_current_state(x)
+ * 03.09.1999 0.18 change read semantics for MIDI to match
+ * OSS more closely; remove possible wakeup race
+ * 21.10.1999 0.19 Round sampling rates, requested by
+ * Kasamatsu Kenichi <t29w0267@ip.media.kyoto-u.ac.jp>
+ * 27.10.1999 0.20 Added SigmaTel 3D enhancement string
+ * Codec ID printing changes
+ * 28.10.1999 0.21 More waitqueue races fixed
+ * Joe Cotellese <joec@ensoniq.com>
+ * Changed PCI detection routine so we can more easily
+ * detect ES137x chip and derivatives.
+ * 05.01.2000 0.22 Should now work with rev7 boards; patch by
+ * Eric Lemar, elemar@cs.washington.edu
+ * 08.01.2000 0.23 Prevent some ioctl's from returning bad count values on underrun/overrun;
+ * Tim Janik's BSE (Bedevilled Sound Engine) found this
+ * 07.02.2000 0.24 Use pci_alloc_consistent and pci_register_driver
+ * 07.02.2000 0.25 Use ac97_codec
+ * 01.03.2000 0.26 SPDIF patch by Mikael Bouillot <mikael.bouillot@bigfoot.com>
+ * Use pci_module_init
+ * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask
+ * 12.12.2000 0.28 More dma buffer initializations, patch from
+ * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
+ * 05.01.2001 0.29 Hopefully updates will not be required anymore when Creative bumps
+ * the CT5880 revision.
+ * suggested by Stephan Müller <smueller@chronox.de>
+ * 31.01.2001 0.30 Register/Unregister gameport
+ * Fix SETTRIGGER non OSS API conformity
+ * 14.07.2001 0.31 Add list of laptops needing amplifier control
+ * 03.01.2003 0.32 open_mode fixes from Georg Acher <acher@in.tum.de>

+ * Supported devices:
+ * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
+ * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
+ * /dev/midi simple MIDI UART interface, no ioctl
+ *
+ * Revision history
+ * 10.11.1998 0.1 Initial release (without any hardware)
+ * 22.03.1999 0.2 cinfo.blocks should be reset after GETxPTR ioctl.
+ * reported by Johan Maes <joma@telindus.be>
+ * return EAGAIN instead of EBUSY when O_NONBLOCK
+ * read/write cannot be executed
+ * 07.04.1999 0.3 implemented the following ioctl's: SOUND_PCM_READ_RATE,
+ * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
+ * Alpha fixes reported by Peter Jones <pjones@redhat.com>
+ * 15.06.1999 0.4 Fix bad allocation bug.
+ * Thanks to Deti Fliegl <fliegl@in.tum.de>
+ * 28.06.1999 0.5 Add pci_set_master
+ * 12.08.1999 0.6 Fix MIDI UART crashing the driver
+ * Changed mixer semantics from OSS documented
+ * behaviour to OSS "code behaviour".
+ * Recording might actually work now.
+ * The real DDMA controller address register is at PCI config
+ * 0x60, while the register at 0x18 is used as a placeholder
+ * register for BIOS address allocation. This register
+ * is supposed to be copied into 0x60, according
+ * to the Solo1 datasheet. When I do that, I can access
+ * the DDMA registers except the mask bit, which
+ * is stuck at 1. When I copy the contents of 0x18 +0x10
+ * to the DDMA base register, everything seems to work.
+ * The fun part is that the Windows Solo1 driver doesn't
+ * seem to do these tricks.
+ * Bugs remaining: plops and clicks when starting/stopping playback
+ * 31.08.1999 0.7 add spin_lock_init
+ * replaced current->state = x with set_current_state(x)
+ * 03.09.1999 0.8 change read semantics for MIDI to match
+ * OSS more closely; remove possible wakeup race
+ * 07.10.1999 0.9 Fix initialization; complain if sequencer writes time out
+ * Revised resource grabbing for the FM synthesizer
+ * 28.10.1999 0.10 More waitqueue races fixed
+ * 09.12.1999 0.11 Work around stupid Alpha port issue (virt_to_bus(kmalloc(GFP_DMA)) > 16M)
+ * Disabling recording on Alpha
+ * 12.01.2000 0.12 Prevent some ioctl's from returning bad count values on underrun/overrun;
+ * Tim Janik's BSE (Bedevilled Sound Engine) found this

+ drivers/sound/harmony.c
+
+ This is a sound driver for ASP's and Lasi's Harmony sound chip
+ and is unlikely to be used for anything other than on a HP PA-RISC.
+
+ Harmony is found in HP 712s, 715/new and many other GSC based machines.
+ On older 715 machines you'll find the technically identical chip
+ called 'Vivace'. Both Harmony and Vicace are supported by this driver.

+ - add private ioctl for selecting line- or microphone input
+ (only one of them is available at the same time)
+ - add module parameters

+ *
+ *
+ * Intel 810 theory of operation
+ *
+ * The chipset provides three DMA channels that talk to an AC97
+ * CODEC (AC97 is a digital/analog mixer standard). At its simplest
+ * you get 48Khz audio with basic volume and mixer controls. At the
+ * best you get rate adaption in the codec. We set the card up so
+ * that we never take completion interrupts but instead keep the card
+ * chasing its tail around a ring buffer. This is needed for mmap
+ * mode audio and happens to work rather well for non-mmap modes too.
+ *
+ * The board has one output channel for PCM audio (supported) and
+ * a stereo line in and mono microphone input. Again these are normally
+ * locked to 48Khz only. Right now recording is not finished.
+ *
+ * There is no midi support, no synth support. Use timidity. To get
+ * esd working you need to use esd -r 48000 as it won't probe 48KHz
+ * by default. mpg123 can't handle 48Khz only audio so use xmms.
+ *
+ * Fix The Sound On Dell
+ *
+ * Not everyone uses 48KHz. We know of no way to detect this reliably
+ * and certainly not to get the right data. If your i810 audio sounds
+ * stupid you may need to investigate other speeds. According to Analog
+ * they tend to use a 14.318MHz clock which gives you a base rate of
+ * 41194Hz.
+ *
+ * This is available via the 'ftsodell=1' option.
+ *
+ * If you need to force a specific rate set the clocking= option
+ *
+ * This driver is cursed. (Ben LaHaise)
+ *
+ * ICH 3 caveats
+ * Intel errata #7 for ICH3 IO. We need to disable SMI stuff
+ * when codec probing. [Not Yet Done]
+ *
+ * ICH 4 caveats
+ *
+ * The ICH4 has the feature, that the codec ID doesn't have to be
+ * congruent with the IO connection.
+ *
+ * Therefore, from driver version 0.23 on, there is a "codec ID" <->
+ * "IO register base offset" mapping (card->ac97_id_map) field.
+ *
+ * Juergen "George" Sawinski (jsaw)

+ * Module command line parameters:
+ *
+ * Supported devices:
+ * /dev/dsp standard OSS /dev/dsp device
+ * /dev/mixer standard OSS /dev/mixer device
+ *
+ * Notes:
+ *
+ * 1. Much of the OSS buffer allocation, ioctl's, and mmap'ing are
+ * taken, slightly modified or not at all, from the ES1371 driver,
+ * so refer to the credits in es1371.c for those. The rest of the
+ * code (probe, open, read, write, the ISR, etc.) is new.
+ * 2. The following support is untested:
+ * * Memory mapping the audio buffers, and the ioctl controls that go
+ * with it.
+ * * S/PDIF output.
+ * * I2S support.
+ * 3. The following is not supported:
+ * * legacy audio mode.
+ * 4. Support for volume button interrupts is implemented but doesn't
+ * work yet.
+ *
+ * Revision history
+ * 02.08.2001 Initial release
+ * 06.22.2001 Added I2S support
+ * 07.30.2003 Removed initialisation to zero for static variables
+ * (spdif[NR_DEVICE], i2s_fmt[NR_DEVICE], and devindex)

+ * (c) Copyright 1999 Alan Cox <alan.cox@linux.org>
+ *
+ * Based heavily on SonicVibes.c:
+ * Copyright (C) 1998-1999 Thomas Sailer (sailer@ife.ee.ethz.ch)
+ *
+ * Heavily modified by Zach Brown <zab@zabbo.net> based on lunch
+ * with ESS engineers. Many thanks to Howard Kim for providing
+ * contacts and hardware. Honorable mention goes to Eric
+ * Brombaugh for all sorts of things. Best regards to the
+ * proprietors of Hack Central for fine lodging.
+ *
+ * Supported devices:
+ * /dev/dsp0-3 standard /dev/dsp device, (mostly) OSS compatible
+ * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
+ *
+ * Hardware Description
+ *
+ * A working Maestro setup contains the Maestro chip wired to a
+ * codec or 2. In the Maestro we have the APUs, the ASSP, and the
+ * Wavecache. The APUs can be though of as virtual audio routing
+ * channels. They can take data from a number of sources and perform
+ * basic encodings of the data. The wavecache is a storehouse for
+ * PCM data. Typically it deals with PCI and interracts with the
+ * APUs. The ASSP is a wacky DSP like device that ESS is loth
+ * to release docs on. Thankfully it isn't required on the Maestro
+ * until you start doing insane things like FM emulation and surround
+ * encoding. The codecs are almost always AC-97 compliant codecs,
+ * but it appears that early Maestros may have had PT101 (an ESS
+ * part?) wired to them. The only real difference in the Maestro
+ * families is external goop like docking capability, memory for
+ * the ASSP, and initialization differences.
+ *
+ * Driver Operation
+ *
+ * We only drive the APU/Wavecache as typical DACs and drive the
+ * mixers in the codecs. There are 64 APUs. We assign 6 to each
+ * /dev/dsp? device. 2 channels for output, and 4 channels for
+ * input.
+ *
+ * Each APU can do a number of things, but we only really use
+ * 3 basic functions. For playback we use them to convert PCM
+ * data fetched over PCI by the wavecahche into analog data that
+ * is handed to the codec. One APU for mono, and a pair for stereo.
+ * When in stereo, the combination of smarts in the APU and Wavecache
+ * decide which wavecache gets the left or right channel.
+ *
+ * For record we still use the old overly mono system. For each in
+ * coming channel the data comes in from the codec, through a 'input'
+ * APU, through another rate converter APU, and then into memory via
+ * the wavecache and PCI. If its stereo, we mash it back into LRLR in
+ * software. The pass between the 2 APUs is supposedly what requires us
+ * to have a 512 byte buffer sitting around in wavecache/memory.
+ *
+ * The wavecache makes our life even more fun. First off, it can
+ * only address the first 28 bits of PCI address space, making it
+ * useless on quite a few architectures. Secondly, its insane.
+ * It claims to fetch from 4 regions of PCI space, each 4 meg in length.
+ * But that doesn't really work. You can only use 1 region. So all our
+ * allocations have to be in 4meg of each other. Booo. Hiss.
+ * So we have a module parameter, dsps_order, that is the order of
+ * the number of dsps to provide. All their buffer space is allocated
+ * on open time. The sonicvibes OSS routines we inherited really want
+ * power of 2 buffers, so we have all those next to each other, then
+ * 512 byte regions for the recording wavecaches. This ends up
+ * wasting quite a bit of memory. The only fixes I can see would be
+ * getting a kernel allocator that could work in zones, or figuring out
+ * just how to coerce the WP into doing what we want.
+ *
+ * The indirection of the various registers means we have to spinlock
+ * nearly all register accesses. We have the main register indirection
+ * like the wave cache, maestro registers, etc. Then we have beasts
+ * like the APU interface that is indirect registers gotten at through
+ * the main maestro indirection. Ouch. We spinlock around the actual
+ * ports on a per card basis. This means spinlock activity at each IO
+ * operation, but the only IO operation clusters are in non critical
+ * paths and it makes the code far easier to follow. Interrupts are
+ * blocked while holding the locks because the int handler has to
+ * get at some of them :(. The mixer interface doesn't, however.
+ * We also have an OSS state lock that is thrown around in a few
+ * places.
+ *
+ * This driver has brute force APM suspend support. We catch suspend
+ * notifications and stop all work being done on the chip. Any people
+ * that try between this shutdown and the real suspend operation will
+ * be put to sleep. When we resume we restore our software state on
+ * the chip and wake up the people that were using it. The code thats
+ * being used now is quite dirty and assumes we're on a uni-processor
+ * machine. Much of it will need to be cleaned up for SMP ACPI or
+ * similar.
+ *
+ * We also pay attention to PCI power management now. The driver
+ * will power down units of the chip that it knows aren't needed.
+ * The WaveProcessor and company are only powered on when people
+ * have /dev/dsp*s open. On removal the driver will
+ * power down the maestro entirely. There could still be
+ * trouble with BIOSen that magically change power states
+ * themselves, but we'll see.
+ *
+ * History
+ * v0.15 - May 21 2001 - Marcus Meissner <mm@caldera.de>
+ * Ported to Linux 2.4 PCI API. Some clean ups, global devs list
+ * removed (now using pci device driver data).
+ * PM needs to be polished still. Bumped version.
+ * (still kind of v0.14) May 13 2001 - Ben Pfaff <pfaffben@msu.edu>
+ * Add support for 978 docking and basic hardware volume control

+ * required hacking some suspend/resume/check paths
+ * make static compilation work
+ * v0.14 - Jan 28 2000 - Zach Brown <zab@redhat.com>
+ * add PCI power management through ACPI regs.

+ * fix maestro 1 clock freq "bug", remove pt101 support
+ * v0.10 - Oct 28 1999 - Zach Brown <zab@redhat.com>
+ * aha, so, sometimes the WP writes a status word to offset 0
+ * from one of the PCMBARs. rearrange allocation accordingly..
+ * cheers again to Eric for being a good hacker in investigating this.
+ * Jeroen Hoogervorst submits 7500 fix out of nowhere. yay. :)
+ * v0.09 - Oct 23 1999 - Zach Brown <zab@redhat.com>

+ * v0.08 - Oct 20 1999 - Zach Brown <zab@redhat.com>
+ * Fix initial buflen bug. I am so smart. also smp compiling..
+ * I owe Eric yet another beer: fixed recmask, igain,
+ * muting, and adc sync consistency. Go Team.
+ * v0.07 - Oct 4 1999 - Zach Brown <zab@redhat.com>
+ * tweak adc/dac, formating, and stuff to allow full duplex
+ * allocate dsps memory at open() so we can fit in the wavecache window
+ * fix wavecache braindamage. again. no more scribbling?

+ * endianness
+ * do smart things with ac97 2.0 bits.
+ * dual codecs
+ * leave 54->61 open
+ *
+ * it also would be fun to have a mode that would not use pci dma at all
+ * but would copy into the wavecache on board memory and use that
+ * on architectures that don't like the maestro's pci dma ickiness.

+ * I need to thank many people for helping make this driver happen.
+ * As always, Eric Brombaugh was a hacking machine and killed many bugs
+ * that I was too dumb to notice. Howard Kim at ESS provided reference boards
+ * and as much docs as he could. Todd and Mick at Dell tested snapshots on
+ * an army of laptops. msw and deviant at Red Hat also humoured me by hanging
+ * their laptops every few hours in the name of science.
+ *
+ * Shouts go out to Mike "DJ XPCom" Ang.
+ *
+ * History
+ * v1.23 - Jun 5 2002 - Michael Olson <olson@cs.odu.edu>
+ * added a module option to allow selection of GPIO pin number
+ * for external amp
+ * v1.22 - Feb 28 2001 - Zach Brown <zab@zabbo.net>
+ * allocate mem at insmod/setup, rather than open
+ * limit pci dma addresses to 28bit, thanks guys.
+ * v1.21 - Feb 04 2001 - Zach Brown <zab@zabbo.net>
+ * fix up really dumb notifier -> suspend oops
+ * v1.20 - Jan 30 2001 - Zach Brown <zab@zabbo.net>
+ * get rid of pm callback and use pci_dev suspend/resume instead
+ * m3_probe cleanups, including pm oops think-o
+ * v1.10 - Jan 6 2001 - Zach Brown <zab@zabbo.net>
+ * revert to lame remap_page_range mmap() just to make it work
+ * record mmap fixed.
+ * fix up incredibly broken open/release resource management
+ * duh. fix record format setting.
+ * add SMP locking and cleanup formatting here and there
+ * v1.00 - Dec 16 2000 - Zach Brown <zab@zabbo.net>
+ * port to sexy 2.4 interfaces
+ * properly align instance allocations so recording works
+ * clean up function namespace a little :/
+ * update PCI IDs based on mail from ESS
+ * arbitrarily bump version number to show its 2.4 now,
+ * 2.2 will stay 0., oss_audio port gets 2.
+ * v0.03 - Nov 05 2000 - Zach Brown <zab@zabbo.net>
+ * disable recording but allow dsp to be opened read
+ * pull out most silly compat defines
+ * v0.02 - Nov 04 2000 - Zach Brown <zab@zabbo.net>
+ * changed clocking setup for m3, slowdown fixed.
+ * codec reset is hopefully reliable now
+ * rudimentary apm/power management makes suspend/resume work
+ * v0.01 - Oct 31 2000 - Zach Brown <zab@zabbo.net>
+ * first release
+ * v0.00 - Sep 09 2000 - Zach Brown <zab@zabbo.net>
+ * first pass derivation from maestro.c
+ *
+ * TODO
+ * in/out allocated contiguously so fullduplex mmap will work?
+ * no beep on init (mute)
+ * resetup msrc data memory if freq changes?
+ *
+ * --
+ *
+ * Allow me to ramble a bit about the m3 architecture. The core of the
+ * chip is the 'assp', the custom ESS dsp that runs the show. It has
+ * a small amount of code and data ram. ESS drops binary dsp code images
+ * on our heads, but we don't get to see specs on the dsp.
+ *
+ * The constant piece of code on the dsp is the 'kernel'. It also has a
+ * chunk of the dsp memory that is statically set aside for its control
+ * info. This is the KDATA defines in maestro3.h. Part of its core
+ * data is a list of code addresses that point to the pieces of DSP code
+ * that it should walk through in its loop. These other pieces of code
+ * do the real work. The kernel presumably jumps into each of them in turn.
+ * These code images tend to have their own data area, and one can have
+ * multiple data areas representing different states for each of the 'client
+ * instance' code portions. There is generally a list in the kernel data
+ * that points to the data instances for a given piece of code.
+ *
+ * We've only been given the binary image for the 'minisrc', mini sample
+ * rate converter. This is rather annoying because it limits the work
+ * we can do on the dsp, but it also greatly simplifies the job of managing
+ * dsp data memory for the code and data for our playing streams :). We
+ * statically allocate the minisrc code into a region we 'know' to be free
+ * based on the map of the binary kernel image we're loading. We also
+ * statically allocate the data areas for the maximum number of pcm streams
+ * we can be dealing with. This max is set by the length of the static list
+ * in the kernel data that records the number of minisrc data regions we
+ * can have. Thats right, all software dsp mixing with static code list
+ * limits. Rock.
+ *
+ * How sound goes in and out is still a relative mystery. It appears
+ * that the dsp has the ability to get input and output through various
+ * 'connections'. To do IO from or to a connection, you put the address
+ * of the minisrc client area in the static kernel data lists for that
+ * input or output. so for pcm -> dsp -> mixer, we put the minisrc data
+ * instance in the DMA list and also in the list for the mixer. I guess
+ * it Just Knows which is in/out, and we give some dma control info that
+ * helps. There are all sorts of cool inputs/outputs that it seems we can't
+ * use without dsp code images that know how to use them.
+ *
+ * So at init time we preload all the memory allocation stuff and set some
+ * system wide parameters. When we really get a sound to play we build
+ * up its minisrc header (stream parameters, buffer addresses, input/output
+ * settings). Then we throw its header on the various lists. We also
+ * tickle some KDATA settings that ask the assp to raise clock interrupts
+ * and do some amount of software mixing before handing data to the ac97.
+ *
+ * Sorry for the vague details. Feel free to ask Eric or myself if you
+ * happen to be trying to use this driver elsewhere. Please accept my
+ * apologies for the quality of the OSS support code, its passed through
+ * too many hands now and desperately wants to be rethought.

+ * This code is derived from ite8172.c, which is written by Steve Longerbeam.
+ *
+ * Features:
+ * Currently we only support the following capabilities:
+ * . mono output to PCM L/R (line out).
+ * . stereo output to PCM L/R (line out).
+ * . mono input from PCM L (line in).
+ * . stereo output from PCM (line in).
+ * . sampling rate at 48k or variable sampling rate
+ * . support /dev/dsp, /dev/mixer devices, standard OSS devices.
+ * . only support 16-bit PCM format (hardware limit, no software
+ * translation)
+ * . support duplex, but no trigger or realtime.
+ *
+ * Specifically the following are not supported:
+ * . app-set frag size.
+ * . mmap'ed buffer access
+ */

+/*
+ * Original comments from ite8172.c file.
+ */
+
+/*
+ *
+ * Notes:
+ *
+ * 1. Much of the OSS buffer allocation, ioctl's, and mmap'ing are
+ * taken, slightly modified or not at all, from the ES1371 driver,
+ * so refer to the credits in es1371.c for those. The rest of the
+ * code (probe, open, read, write, the ISR, etc.) is new.
+ * 2. The following support is untested:

+ * 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.

+ * sound/opl3sa2.c
+ *
+ * A low level driver for Yamaha OPL3-SA2 and SA3 cards.
+ * NOTE: All traces of the name OPL3-SAx have now (December 2000) been
+ * removed from the driver code, as an email exchange with Yamaha
+ * provided the information that the YMF-719 is indeed just a
+ * re-badged 715.
+ *
+ * Copyright 1998-2001 Scott Murray <scott@spiteful.org>
+ *
+ * Originally based on the CS4232 driver (in cs4232.c) by Hannu Savolainen
+ * and others. Now incorporates code/ideas from pss.c, also by Hannu
+ * Savolainen. Both of those files are distributed with the following
+ * license:

+ *
+ * Change History
+ * --------------
+ * Scott Murray Original driver (Jun 14, 1998)
+ * Paul J.Y. Lahaie Changed probing / attach code order
+ * Scott Murray Added mixer support (Dec 03, 1998)
+ * Scott Murray Changed detection code to be more forgiving,
+ * added force option as last resort,
+ * fixed ioctl return values. (Dec 30, 1998)
+ * Scott Murray Simpler detection code should work all the time now
+ * (with thanks to Ben Hutchings for the heuristic),
+ * removed now unnecessary force option. (Jan 5, 1999)
+ * Christoph Hellwig Adapted to module_init/module_exit (Mar 4, 2000)
+ * Scott Murray Reworked SA2 versus SA3 mixer code, updated chipset
+ * version detection code (again!). (Dec 5, 2000)
+ * Scott Murray Adjusted master volume mixer scaling. (Dec 6, 2000)
+ * Scott Murray Based on a patch by Joel Yliluoma (aka Bisqwit),
+ * integrated wide mixer and adjusted mic, bass, treble
+ * scaling. (Dec 6, 2000)
+ * Scott Murray Based on a patch by Peter Englmaier, integrated
+ * ymode and loopback options. (Dec 6, 2000)
+ * Scott Murray Inspired by a patch by Peter Englmaier, and based on
+ * what ALSA does, added initialization code for the
+ * default DMA and IRQ settings. (Dec 6, 2000)
+ * Scott Murray Added some more checks to the card detection code,
+ * based on what ALSA does. (Dec 12, 2000)
+ * Scott Murray Inspired by similar patches from John Fremlin,
+ * Jim Radford, Mike Rolig, and Ingmar Steen, added 2.4
+ * ISA PnP API support, mainly based on bits from
+ * sb_card.c and awe_wave.c. (Dec 12, 2000)
+ * Scott Murray Some small cleanups to the init code output.
+ * (Jan 7, 2001)
+ * Zwane Mwaikambo Added PM support. (Dec 4 2001)
+ *
+ * Adam Belay Converted driver to new PnP Layer (Oct 12, 2002)
+ * Zwane Mwaikambo Code, data structure cleanups. (Feb 15 2002)
+ * Zwane Mwaikambo Free resources during auxiliary device probe
+ * failures (Apr 29 2002)

+ *
+ *
+ * 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 fireware 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

+/* (C) 2000 Guenter Geiger <geiger@debian.org>
+ with copy/pastes from the driver of Winfried Ritsch <ritsch@iem.kug.ac.at>
+ based on es1370.c
+
+
+
+ * 10 Jan 2001: 0.1 initial version
+ * 19 Jan 2001: 0.2 fixed bug in select()
+ * 27 Apr 2001: 0.3 more than one card usable
+ * 11 May 2001: 0.4 fixed for SMP, included into kernel source tree
+ * 17 May 2001: 0.5 draining code didn't work on new cards
+ * 18 May 2001: 0.6 remove synchronize_irq() call
+ * 17 Jul 2001: 0.7 updated xrmectrl to make it work for newer cards
+ * 2 feb 2002: 0.8 fixed pci device handling, see below for patches from Heiko (Thanks!)
+ Marcus Meissner <Marcus.Meissner@caldera.de>
+
+ Modifications - Heiko Purnhagen <purnhage@tnt.uni-hannover.de>
+ HP20020108 fixed handling of "large" read()
+ HP20020116 towards REV 1.5 support, based on ALSA's card-rme9652.c
+ HP20020118 made mixer ioctl and handling of devices>1 more safe
+ HP20020201 fixed handling of "large" read() properly
+ added REV 1.5 S/P-DIF receiver support
+ SNDCTL_DSP_SPEED now returns the actual speed
+ * 10 Aug 2002: added synchronize_irq() again
+
+TODO:
+ - test more than one card --- done
+ - check for pci IOREGION (see es1370) in rme96xx_probe ??
+ - error detection
+ - mmap interface
+ - mixer mmap interface
+ - mixer ioctl
+ - get rid of noise upon first open (why ??)
+ - allow multiple open (at least for read)
+ - allow multiple open for non overlapping regions
+ - recheck the multiple devices part (offsets of different devices, etc)
+ - do decent draining in _release --- done
+ - SMP support
+ - what about using fragstotal>2 for small fragsize? (HP20020118)
+ - add support for AFMT_S32_LE

+ * 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. Interresting ones are 0x7f, 0x7d and 0x7a. They are
+ * related to the Audio 2 channel. I also was suprised about the consequenses
+ * 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 decribed
+ * 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 allways 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 operation, and uses the
+ * same dma as audio 1: your ess changes into a funny echo machine.
+ *
+ * Received the new 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. It's 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
+ * it's 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
+ * it's 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. Futhermore several devices can be recorded together (which is not
+ * possible with the ES1688.
+ * Besides the separate recording level control for each input, the common
+ * recordig 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

+ * Special thanks to David C. Niemi
+ *
+ *
+ * Module command line parameters:
+ * none so far
+ *
+ *
+ * Supported devices:
+ * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
+ * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
+ * /dev/midi simple MIDI UART interface, no ioctl
+ *
+ * The card has both an FM and a Wavetable synth, but I have to figure
+ * out first how to drive them...
+ *
+ * Revision history
+ * 06.05.1998 0.1 Initial release
+ * 10.05.1998 0.2 Fixed many bugs, esp. ADC rate calculation
+ * First stab at a simple midi interface (no bells&whistles)
+ * 13.05.1998 0.3 Fix stupid cut&paste error: set_adc_rate was called instead of
+ * set_dac_rate in the FMODE_WRITE case in sv_open
+ * Fix hwptr out of bounds (now mpg123 works)
+ * 14.05.1998 0.4 Don't allow excessive interrupt rates
+ * 08.06.1998 0.5 First release using Alan Cox' soundcore instead of miscdevice
+ * 03.08.1998 0.6 Do not include modversions.h
+ * Now mixer behaviour can basically be selected between
+ * "OSS documented" and "OSS actual" behaviour
+ * 31.08.1998 0.7 Fix realplayer problems - dac.count issues
+ * 10.12.1998 0.8 Fix drain_dac trying to wait on not yet initialized DMA
+ * 16.12.1998 0.9 Fix a few f_file & FMODE_ bugs
+ * 06.01.1999 0.10 remove the silly SA_INTERRUPT flag.
+ * hopefully killed the egcs section type conflict
+ * 12.03.1999 0.11 cinfo.blocks should be reset after GETxPTR ioctl.
+ * reported by Johan Maes <joma@telindus.be>
+ * 22.03.1999 0.12 return EAGAIN instead of EBUSY when O_NONBLOCK
+ * read/write cannot be executed
+ * 05.04.1999 0.13 added code to sv_read and sv_write which should detect
+ * lockups of the sound chip and revive it. This is basically
+ * an ugly hack, but at least applications using this driver
+ * won't hang forever. I don't know why these lockups happen,
+ * it might well be the motherboard chipset (an early 486 PCI
+ * board with ALI chipset), since every busmastering 100MB
+ * ethernet card I've tried (Realtek 8139 and Macronix tulip clone)
+ * exhibit similar behaviour (they work for a couple of packets
+ * and then lock up and can be revived by ifconfig down/up).
+ * 07.04.1999 0.14 implemented the following ioctl's: SOUND_PCM_READ_RATE,
+ * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
+ * Alpha fixes reported by Peter Jones <pjones@redhat.com>
+ * Note: dmaio hack might still be wrong on archs other than i386
+ * 15.06.1999 0.15 Fix bad allocation bug.
+ * Thanks to Deti Fliegl <fliegl@in.tum.de>
+ * 28.06.1999 0.16 Add pci_set_master
+ * 03.08.1999 0.17 adapt to Linus' new __setup/__initcall
+ * added kernel command line options "sonicvibes=reverb" and "sonicvibesdmaio=dmaioaddr"
+ * 12.08.1999 0.18 module_init/__setup fixes
+ * 24.08.1999 0.19 get rid of the dmaio kludge, replace with allocate_resource
+ * 31.08.1999 0.20 add spin_lock_init
+ * use new resource allocation to allocate DDMA IO space
+ * replaced current->state = x with set_current_state(x)
+ * 03.09.1999 0.21 change read semantics for MIDI to match
+ * OSS more closely; remove possible wakeup race
+ * 28.10.1999 0.22 More waitqueue races fixed
+ * 01.12.1999 0.23 New argument to allocate_resource
+ * 07.12.1999 0.24 More allocate_resource semantics change
+ * 08.01.2000 0.25 Prevent some ioctl's from returning bad count values on underrun/overrun;
+ * Tim Janik's BSE (Bedevilled Sound Engine) found this
+ * use Martin Mares' pci_assign_resource
+ * 07.02.2000 0.26 Use pci_alloc_consistent and pci_register_driver
+ * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask
+ * 12.12.2000 0.28 More dma buffer initializations, patch from
+ * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
+ * 31.01.2001 0.29 Register/Unregister gameport
+ * Fix SETTRIGGER non OSS API conformity
+ * 18.05.2001 0.30 PCI probing and error values cleaned up by Marcus
+ * Meissner <mm@caldera.de>
+ * 03.01.2003 0.31 open_mode fixes from Georg Acher <acher@in.tum.de>

+* Module command line parameters:
+* none
+*
+* Supported devices:
+* /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
+* /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
+* /dev/midi simple MIDI UART interface, no ioctl
+*
+* 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.

+ * July 19 2002 Muli Ben-Yehuda <mulix@actcom.co.il>
+ * rewrite the DMA buffer allocation/deallcoation functions, to make it

+ * v0.14.10d
+ * July 19 2002 Muli Ben-Yehuda <mulix@actcom.co.il>

+ * add a missing unlock_set_fmt, remove a superflous lock/unlock pair
+ * with nothing in between.
+ * v0.14.10a
+ * June 21 2002 Muli Ben-Yehuda <mulix@actcom.co.il>
+ * use a debug macro instead of #ifdef CONFIG_DEBUG, trim to 80 columns

+ * Switch to static inline not extern inline (gcc 3)
+ * v0.14.9a
+ * Aug 6 2001 Alan Cox

+ * Locking Notes

+ *
+ * devc->open_lock is a semaphore that is used to enforce the
+ * single reader/single writer rule for /dev/audio. The rule is
+ * that each device may have at most one reader and one writer.
+ * Open will block until the previous client has closed the
+ * device, unless O_NONBLOCK is specified.
+ *
+ * The semaphore devc->io_sema serializes PCM I/O syscalls. This
+ * is unnecessary in Linux 2.2, because the kernel lock
+ * serializes read, write, and ioctl globally, but it's there,
+ * ready for the brave, new post-kernel-lock world.
+ *
+ * Locking between interrupt and baselevel is handled by the
+ * "lock" spinlock in vwsnd_port (one lock each for read and
+ * write). Each half holds the lock just long enough to see what
+ * area it owns and update its pointers. See pcm_output() and
+ * pcm_input() for most of the gory stuff.
+ *
+ * devc->mix_sema serializes all mixer ioctls. This is also
+ * redundant because of the kernel lock.
+ *
+ * The lowest level lock is lith->lithium_lock. It is a
+ * spinlock which is held during the two-register tango of
+ * reading/writing an AD1843 register. See
+ * li_{read,write}_ad1843_reg().

+
+/*
+ * Sample Format Notes
+ *
+ * Lithium's DMA engine has two formats: 16-bit 2's complement
+ * and 8-bit unsigned . 16-bit transfers the data unmodified, 2
+ * bytes per sample. 8-bit unsigned transfers 1 byte per sample
+ * and XORs each byte with 0x80. Lithium can input or output
+ * either mono or stereo in either format.
+ *
+ * The AD1843 has four formats: 16-bit 2's complement, 8-bit
+ * unsigned, 8-bit mu-Law and 8-bit A-Law.
+ *
+ * This driver supports five formats: AFMT_S8, AFMT_U8,
+ * AFMT_MU_LAW, AFMT_A_LAW, and AFMT_S16_LE.
+ *
+ * For AFMT_U8 output, we keep the AD1843 in 16-bit mode, and
+ * rely on Lithium's XOR to translate between U8 and S8.
+ *
+ * For AFMT_S8, AFMT_MU_LAW and AFMT_A_LAW output, we have to XOR
+ * the 0x80 bit in software to compensate for Lithium's XOR.
+ * This happens in pcm_copy_{in,out}().
+ *
+ * Changes:
+ * 11-10-2000 Bartlomiej Zolnierkiewicz <bkz@linux-ide.org>
+ * Added some __init/__exit

+
+/*
+ * Lithium DMA Notes
+ *
+ * Lithium has two dedicated DMA channels for audio. They are known
+ * as comm1 and comm2 (communication areas 1 and 2). Comm1 is for
+ * input, and comm2 is for output. Each is controlled by three
+ * registers: BASE (base address), CFG (config) and CCTL
+ * (config/control).
+ *
+ * Each DMA channel points to a physically contiguous ring buffer in
+ * main memory of up to 8 Kbytes. (This driver always uses 8 Kb.)
+ * There are three pointers into the ring buffer: read, write, and
+ * trigger. The pointers are 8 bits each. Each pointer points to
+ * 32-byte "chunks" of data. The DMA engine moves 32 bytes at a time,
+ * so there is no finer-granularity control.
+ *
+ * In comm1, the hardware updates the write ptr, and software updates
+ * the read ptr. In comm2, it's the opposite: hardware updates the
+ * read ptr, and software updates the write ptr. I designate the
+ * hardware-updated ptr as the hwptr, and the software-updated ptr as
+ * the swptr.
+ *
+ * The trigger ptr and trigger mask are used to trigger interrupts.
+ * From the Lithium spec, section 5.6.8, revision of 12/15/1998:
+ *
+ * Trigger Mask Value
+ *
+ * A three bit wide field that represents a power of two mask
+ * that is used whenever the trigger pointer is compared to its
+ * respective read or write pointer. A value of zero here
+ * implies a mask of 0xFF and a value of seven implies a mask
+ * 0x01. This value can be used to sub-divide the ring buffer
+ * into pie sections so that interrupts monitor the progress of
+ * hardware from section to section.
+ *
+ * My interpretation of that is, whenever the hw ptr is updated, it is
+ * compared with the trigger ptr, and the result is masked by the
+ * trigger mask. (Actually, by the complement of the trigger mask.)
+ * If the result is zero, an interrupt is triggered. I.e., interrupt
+ * if ((hwptr & ~mask) == (trptr & ~mask)). The mask is formed from
+ * the trigger register value as mask = (1 << (8 - tmreg)) - 1.
+ *
+ * In yet different words, setting tmreg to 0 causes an interrupt after
+ * every 256 DMA chunks (8192 bytes) or once per traversal of the
+ * ring buffer. Setting it to 7 caues an interrupt every 2 DMA chunks
+ * (64 bytes) or 128 times per traversal of the ring buffer.

+ *
+ * sound/wavfront.c
+ *
+ * A Linux driver for Turtle Beach WaveFront Series (Maui, Tropez, Tropez Plus)
+ *
+ * This driver supports the onboard wavetable synthesizer (an ICS2115),
+ * including patch, sample and program loading and unloading, conversion
+ * of GUS patches during loading, and full user-level access to all
+ * WaveFront commands. It tries to provide semi-intelligent patch and
+ * sample management as well.
+ *
+ * It also provides support for the ICS emulation of an MPU-401. Full
+ * support for the ICS emulation's "virtual MIDI mode" is provided in
+ * wf_midi.c.
+ *
+ * Support is also provided for the Tropez Plus' onboard FX processor,
+ * a Yamaha YSS225. Currently, code exists to configure the YSS225,
+ * and there is an interface allowing tweaking of any of its memory
+ * addresses. However, I have been unable to decipher the logical
+ * positioning of the configuration info for various effects, so for
+ * now, you just get the YSS225 in the same state as Turtle Beach's
+ * "SETUPSND.EXE" utility leaves it.
+ *
+ * The boards' DAC/ADC (a Crystal CS4232) is supported by cs4232.[co],
+ * This chip also controls the configuration of the card: the wavefront
+ * synth is logical unit 4.
+ *
+ *
+ * Supported devices:
+ *
+ * /dev/dsp - using cs4232+ad1848 modules, OSS compatible
+ * /dev/midiNN and /dev/midiNN+1 - using wf_midi code, OSS compatible
+ * /dev/synth00 - raw synth interface

+/*
+ * sound/wf_midi.c
+ *
+ * The low level driver for the WaveFront ICS2115 MIDI interface(s)
+ * Note that there is also an MPU-401 emulation (actually, a UART-401
+ * emulation) on the CS4232 on the Tropez Plus. This code has nothing
+ * to do with that interface at all.
+ *
+ * The interface is essentially just a UART-401, but is has the
+ * interesting property of supporting what Turtle Beach called
+ * "Virtual MIDI" mode. In this mode, there are effectively *two*
+ * MIDI buses accessible via the interface, one that is routed
+ * solely to/from the external WaveFront synthesizer and the other
+ * corresponding to the pin/socket connector used to link external
+ * MIDI devices to the board.
+ *
+ * This driver fully supports this mode, allowing two distinct
+ * midi devices (/dev/midiNN and /dev/midiNN+1) to be used
+ * completely independently, giving 32 channels of MIDI routing,
+ * 16 to the WaveFront synth and 16 to the external MIDI bus.
+ *
+ * Switching between the two is accomplished externally by the driver
+ * using the two otherwise unused MIDI bytes. See the code for more details.
+ *
+ * NOTE: VIRTUAL MIDI MODE IS ON BY DEFAULT (see wavefront.c)
+ *
+ * The main reason to turn off Virtual MIDI mode is when you want to
+ * tightly couple the WaveFront synth with an external MIDI
+ * device. You won't be able to distinguish the source of any MIDI
+ * data except via SysEx ID, but thats probably OK, since for the most
+ * part, the WaveFront won't be sending any MIDI data at all.
+ *
+ * The main reason to turn on Virtual MIDI Mode is to provide two
+ * completely independent 16-channel MIDI buses, one to the
+ * WaveFront and one to any external MIDI devices. Given the 32
+ * voice nature of the WaveFront, its pretty easy to find a use
+ * for all 16 channels driving just that synth.

+ * TODO:
+ * - Use P44Slot for 44.1 playback (beware of idle buzzing in P44Slot).
+ * - 96KHz playback for DVD - use pitch of 2.0.
+ * - Retain DMA buffer on close, do not wait the end of frame.
+ * - Resolve XXX tagged questions.
+ * - Cannot play 5133Hz.
+ * - 2001/01/07 Consider if we can remove voice_lock, like so:
+ * : Allocate/deallocate voices in open/close under semafore.
+ * : We access voices in interrupt, that only for pcms that open.
+ * voice_lock around playback_prepare closes interrupts for insane duration.
+ * - Revisit the way voice_alloc is done - too confusing, overcomplicated.
+ * Should support various channel types, however.
+ * - Remove prog_dmabuf from read/write, leave it in open.
+ * - 2001/01/07 Replace the OPL3 part of CONFIG_SOUND_YMFPCI_LEGACY code with
+ * native synthesizer through a playback slot.
+ * - 2001/11/29 ac97_save_state
+ * Talk to Kai to remove ac97_save_state before it's too late!
+ * - Second AC97
+ * - Restore S/PDIF - Toshibas have it.
+ *
+ * Kai used pci_alloc_consistent for DMA buffer, which sounds a little
+ * unconventional. However, given how small our fragments can be,
+ * a little uncached access is perhaps better than endless flushing.
+ * On i386 and other I/O-coherent architectures pci_alloc_consistent
+ * is entirely harmless.
