Linux-2.6.12-rc2v2.6.12-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!

+	help
+	  If you have a sound card in your computer, i.e. if it can say more
+	  than an occasional beep, say Y.  Be sure to have all the information
+	  about your sound card and its configuration down (I/O port,
+	  interrupt and DMA channel), because you will be asked for it.
+
+	  You want to read the Sound-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>. General information about
+	  the modular sound system is contained in the files
+	  <file:Documentation/sound/oss/Introduction>.  The file
+	  <file:Documentation/sound/oss/README.OSS> contains some slightly
+	  outdated but still useful information as well.  Newer sound
+	  driver documentation is found in <file:Documentation/sound/alsa/*>.
+
+	  If you have a PnP sound card and you want to configure it at boot
+	  time using the ISA PnP tools (read
+	  <http://www.roestock.demon.co.uk/isapnptools/>), then you need to
+	  compile the sound card support as a module and load that module
+	  after the PnP configuration is finished.  To do this, choose M here
+	  and read <file:Documentation/sound/oss/README.modules>; the module
+	  will be called soundcore.
+
+	  I'm told that even without a sound card, you can make your computer
+	  say more than an occasional beep, by programming the PC speaker.
+	  Kernel patches and supporting utilities to do that are in the pcsp
+	  package, available at <ftp://ftp.infradead.org/pub/pcsp/>.

+/***************************************************************************************************
+*
+* To understand what Alsa Drivers should be doing look at "Writing an Alsa Driver" by Takashi Iwai
+* available in the Alsa doc section on the website		
+* 
+* A few notes to make things clearer. The UDA1341 is hooked up to Serial port 4 on the SA1100.
+* We are using  SSP mode to talk to the UDA1341. The UDA1341 bit & wordselect clocks are generated
+* by this UART. Unfortunately, the clock only runs if the transmit buffer has something in it.
+* So, if we are just recording, we feed the transmit DMA stream a bunch of 0x0000 so that the
+* transmit buffer is full and the clock keeps going. The zeroes come from FLUSH_BASE_PHYS which
+* is a mem loc that always decodes to 0's w/ no off chip access.
+*
+* Some alsa terminology:
+*	frame => num_channels * sample_size  e.g stereo 16 bit is 2 * 16 = 32 bytes
+*	period => the least number of bytes that will generate an interrupt e.g. we have a 1024 byte
+*             buffer and 4 periods in the runtime structure this means we'll get an int every 256
+*             bytes or 4 times per buffer.
+*             A number of the sizes are in frames rather than bytes, use frames_to_bytes and
+*             bytes_to_frames to convert.  The easiest way to tell the units is to look at the
+*             type i.e. runtime-> buffer_size is in frames and its type is snd_pcm_uframes_t
+*             
+*	Notes about the pointer fxn:
+*	The pointer fxn needs to return the offset into the dma buffer in frames.
+*	Interrupts must be blocked before calling the dma_get_pos fxn to avoid race with interrupts.
+*
+*	Notes about pause/resume
+*	Implementing this would be complicated so it's skipped.  The problem case is:
+*	A full duplex connection is going, then play is paused. At this point you need to start xmitting
+*	0's to keep the record active which means you cant just freeze the dma and resume it later you'd
+*	need to	save off the dma info, and restore it properly on a resume.  Yeach!
+*
+*	Notes about transfer methods:
+*	The async write calls fail.  I probably need to implement something else to support them?

+ * This device handler separates the card driver module from sequencer
+ * stuff (sequencer core, synth drivers, etc), so that user can avoid
+ * to spend unnecessary resources e.g. if he needs only listening to
+ * MP3s.
+ *
+ * The card (or lowlevel) driver creates a sequencer device entry
+ * via snd_seq_device_new().  This is an entry pointer to communicate
+ * with the sequencer device "driver", which is involved with the
+ * actual part to communicate with the sequencer core.
+ * Each sequencer device entry has an id string and the corresponding
+ * driver with the same id is loaded when required.  For example,
+ * lowlevel codes to access emu8000 chip on sbawe card are included in
+ * emu8000-synth module.  To activate this module, the hardware
+ * resources like i/o port are passed via snd_seq_device argument.

+/*
+
+  Sequencer MIDI-through client
+
+  This gives a simple midi-through client.  All the normal input events
+  are redirected to output port immediately.
+  The routing can be done via aconnect program in alsa-utils.
+
+  Each client has a static client number 62 (= SNDRV_SEQ_CLIENT_DUMMY).
+  If you want to auto-load this module, you may add the following alias
+  in your /etc/conf.modules file.
+
+	alias snd-seq-client-62  snd-seq-dummy
+
+  The module is loaded on demand for client 62, or /proc/asound/seq/
+  is accessed.  If you don't need this module to be loaded, alias
+  snd-seq-client-62 as "off".  This will help modprobe.
+
+  The number of ports to be created can be specified via the module
+  parameter "ports".  For example, to create four ports, add the
+  following option in /etc/modprobe.conf:
+
+	option snd-seq-dummy ports=4
+
+  The modle option "duplex=1" enables duplex operation to the port.
+  In duplex mode, a pair of ports are created instead of single port,
+  and events are tunneled between pair-ports.  For example, input to
+  port A is sent to output port of another port B and vice versa.
+  In duplex mode, each port has DUPLEX capability.

+
+NOTE: the current implementation of the port structure as a linked list is
+not optimal for clients that have many ports. For sending messages to all
+subscribers of a port we first need to find the address of the port
+structure, which means we have to traverse the list. A direct access table
+(array) would be better, but big preallocated arrays waste memory.
+
+Possible actions:
+
+1) leave it this way, a client does normaly does not have more than a few
+ports
+
+2) replace the linked list of ports by a array of pointers which is
+dynamicly kmalloced. When a port is added or deleted we can simply allocate
+a new array, copy the corresponding pointers, and delete the old one. We
+then only need a pointer to this array, and an integer that tells us how
+much elements are in array.

+ * MAJOR CHANGES
+ *   Nov. 13, 1999	Takashi Iwai <iwai@ww.uni-erlangen.de>
+ *     - Queues are allocated dynamically via ioctl.
+ *     - When owner client is deleted, all owned queues are deleted, too.
+ *     - Owner of unlocked queue is kept unmodified even if it is
+ *	 manipulated by other clients.
+ *     - Owner field in SET_QUEUE_OWNER ioctl must be identical with the
+ *       caller client.  i.e. Changing owner to a third client is not
+ *       allowed.
+ *
+ *  Aug. 30, 2000	Takashi Iwai
+ *     - Queues are managed in static array again, but with better way.
+ *       The API itself is identical.
+ *     - The queue is locked when queue_t pinter is returned via
+ *       queueptr().  This pointer *MUST* be released afterward by
+ *       queuefree(ptr).
+ *     - Addition of experimental sync support.

+ *      This driver is for the 'Mark Of The Unicorn' (MOTU)
+ *      MidiTimePiece AV multiport MIDI interface 
+ *
+ *      IOPORTS
+ *      -------
+ *      8 MIDI Ins and 8 MIDI outs
+ *      Video Sync In (BNC), Word Sync Out (BNC), 
+ *      ADAT Sync Out (DB9)
+ *      SMPTE in/out (1/4")
+ *      2 programmable pedal/footswitch inputs and 4 programmable MIDI controller knobs.
+ *      Macintosh RS422 serial port
+ *      RS422 "network" port for ganging multiple MTP's
+ *      PC Parallel Port ( which this driver currently uses )
+ *
+ *      MISC FEATURES
+ *      -------------
+ *      Hardware MIDI routing, merging, and filtering   
+ *      MIDI Synchronization to Video, ADAT, SMPTE and other Clock sources
+ *      128 'scene' memories, recallable from MIDI program change
+ *
+ *
+ * ChangeLog
+ * Jun 11 2001	Takashi Iwai <tiwai@suse.de>
+ *      - Recoded & debugged
+ *      - Added timer interrupt for midi outputs
+ *      - hwports is between 1 and 8, which specifies the number of hardware ports.
+ *        The three global ports, computer, adat and broadcast ports, are created
+ *        always after h/w and remote ports.

+ * ---------------------------
+ * After receiving a interrupt, it is important to indicate to the UART that
+ * this has been done. 
+ * For a Rx interrupt, this is done by reading the received byte.
+ * For a Tx interrupt this is done by either:
+ * a) Writing a byte
+ * b) Reading the IIR
+ * It is particularly important to read the IIR if a Tx interrupt is received
+ * when there is no data in tx_buff[], as in this case there no other
+ * indication that the interrupt has been serviced, and it remains outstanding
+ * indefinitely. This has the curious side effect that and no further interrupts
+ * will be generated from this device AT ALL!!.
+ * It is also desirable to clear outstanding interrupts when the device is
+ * opened/closed.
+ *
+ *
+ * Note that some devices need OUT2 to be set before they will generate
+ * interrupts at all. (Possibly tied to an internal pull-up on CTS?)

+ * VIRTUAL RAW MIDI DEVICE CARDS
+ *
+ * This dummy card contains up to 4 virtual rawmidi devices.
+ * They are not real rawmidi devices but just associated with sequencer
+ * clients, so that any input/output sources can be connected as a raw
+ * MIDI device arbitrary.
+ * Also, multiple access is allowed to a single rawmidi device.
+ *
+ * Typical usage is like following:
+ * - Load snd-virmidi module.
+ *	# modprobe snd-virmidi index=2
+ *   Then, sequencer clients 72:0 to 75:0 will be created, which are
+ *   mapped from /dev/snd/midiC1D0 to /dev/snd/midiC1D3, respectively.
+ *
+ * - Connect input/output via aconnect.
+ *	% aconnect 64:0 72:0	# keyboard input redirection 64:0 -> 72:0
+ *	% aconnect 72:0 65:0	# output device redirection 72:0 -> 65:0
+ *
+ * - Run application using a midi device (eg. /dev/snd/midiC1D0)

+ * STRATEGY
+ *  for playback, we send series of "chunks", which size is equal with the
+ *  IBL size, typically 126 samples.  at each end of chunk, the end-of-buffer
+ *  interrupt is notified, and the interrupt handler will feed the next chunk.
+ *
+ *  the current position is calculated from the sample count RMH.
+ *  pipe->transferred is the counter of data which has been already transferred.
+ *  if this counter reaches to the period size, snd_pcm_period_elapsed() will
+ *  be issued.
+ *
+ *  for capture, the situation is much easier.
+ *  to get a low latency response, we'll check the capture streams at each
+ *  interrupt (capture stream has no EOB notification).  if the pending
+ *  data is accumulated to the period size, snd_pcm_period_elapsed() is
+ *  called and the pointer is updated.
+ *
+ *  the current point of read buffer is kept in pipe->hw_ptr.  note that
+ *  this is in bytes.
+ *
+ *
+ * TODO
+ *  - linked trigger for full-duplex mode.
+ *  - scheduled action on the stream.

+ * NOTES
+ *
+ *  The extended registers contain mixer settings which are largely
+ *  untapped for the time being.
+ *
+ *  MPU401 and SPDIF are not supported yet.  I don't have the hardware
+ *  to aid in coding and testing, so I won't bother.
+ *
+ *  To quickly load the module,
+ *
+ *  modprobe -a snd-cmi8330 sbport=0x220 sbirq=5 sbdma8=1
+ *    sbdma16=5 wssport=0x530 wssirq=11 wssdma=0
+ *
+ *  This card has two mixers and two PCM devices.  I've cheesed it such
+ *  that recording and playback can be done through the same device.
+ *  The driver "magically" routes the capturing to the AD1848 codec,
+ *  and playback to the SB16 codec.  This allows for full-duplex mode
+ *  to some extent.
+ *  The utilities in alsa-utils are aware of both devices, so passing
+ *  the appropriate parameters to amixer and alsactl will give you
+ *  full control over both mixers.

+/* GENERAL NOTES:
+ *
+ * BUGS:
+ * - There are pops (we can't delay in trigger function, cause midlevel 
+ *   often need to trigger down and then up very quickly).
+ *   Any ideas?
+ * - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
+ */
+
+/*
+ * ES1868  NOTES:
+ * - The chip has one half duplex pcm (with very limited full duplex support).
+ *
+ * - Duplex stereophonic sound is impossible.
+ * - Record and playback must share the same frequency rate.
+ *
+ * - The driver use dma2 for playback and dma1 for capture.
+ */
+
+/*
+ * ES1869 NOTES:
+ *
+ * - there are a first full duplex pcm and a second playback only pcm
+ *   (incompatible with first pcm capture)
+ * 
+ * - there is support for the capture volume and ESS Spatializer 3D effect.
+ *
+ * - contrarily to some pages in DS_1869.PDF the rates can be set
+ *   independently.
+ *
+ * BUGS:
+ *
+ * - There is a major trouble I noted:
+ *
+ *   using both channel for playback stereo 16 bit samples at 44100 Hz
+ *   the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
+ *   
+ *   The same happens using Audio1 for captureing.
+ *
+ *   The Windows driver does not suffer of this (although it use Audio1
+ *   only for captureing). I'm unable to discover why.

+ *  Routines for control of 16-bit SoundBlaster cards and clones
+ *  Note: This is very ugly hardware which uses one 8-bit DMA channel and
+ *        second 16-bit DMA channel. Unfortunately 8-bit DMA channel can't
+ *        transfer 16-bit samples and 16-bit DMA channels can't transfer
+ *        8-bit samples. This make full duplex more complicated than
+ *        can be... People, don't buy these soundcards for full 16-bit
+ *        duplex!!!
+ *  Note: 16-bit wide is assigned to first direction which made request.
+ *        With full duplex - playback is preferred with abstract layer.
+ *
+ *  Note: Some chip revisions have hardware bug. Changing capture
+ *        channel from full-duplex 8bit DMA to 16bit DMA will block
+ *        16bit DMA transfers from DSP chip (capture) until 8bit transfer
+ *        to DSP chip (playback) starts. This bug can be avoided with
+ *        "16bit DMA Allocation" setting set to Playback or Capture.

+/* 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 and 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
+ * busses to be used completely independently, giving 32 channels of
+ * MIDI routing, 16 to the WaveFront synth and 16 to the external MIDI
+ * bus. The devices are named /dev/snd/midiCnD0 and /dev/snd/midiCnD1,
+ * where `n' is the card number. Note that the device numbers may be
+ * something other than 0 and 1 if the CS4232 UART/MPU-401 interface
+ * is enabled.
+ *
+ * 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 lowlevel/isa/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.

+		   this driver, and so a complete reset (back to General MIDI,
+		   or theoretically some other configuration) is the
+		   responsibility of the user level library. 
+
+		   To try to do this in the kernel would be a little

+
+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.

+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

+
+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.

+
+	  If you compile the driver into the kernel and don't want to use
+	  isapnp, you have to add "sb=<io>,<irq>,<dma>,<dma2>" to the kernel

+	  Answering Y is usually a safe and recommended choice, however some
+	  cards may have software (TSR) FM emulation. Enabling FM support with
+	  these cards may cause trouble (I don't currently know of any such
+	  cards, however). Please read the file
+	  <file:Documentation/sound/oss/OPL3> if your card has an OPL3 chip.
+

+	  of this card.
+
+	  The Gallant's Audio Excel DSP 16 card can emulate either an SBPro or

+ * Audio Command Interface (ACI) driver (sound/aci.c)
+ *
+ * ACI is a protocol used to communicate with the microcontroller on
+ * some sound cards produced by miro, e.g. the miroSOUND PCM12 and
+ * PCM20. The ACI has been developed for miro by Norberto Pellicci
+ * <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
+ * -
+ *
+ * Revision history:
+ *
+ *   1995-11-10  Markus Kuhn <mskuhn@cip.informatik.uni-erlangen.de>
+ *        First version written.
+ *   1995-12-31  Markus Kuhn
+ *        Second revision, general code cleanup.
+ *   1996-05-16	 Hannu Savolainen
+ *	  Integrated with other parts of the driver.
+ *   1996-05-28  Markus Kuhn
+ *        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 
+ *	  complete modularisation.
+ *   2000-06-20  Robert Siemer <Robert.Siemer@gmx.de>
+ *        Don't initialize the CS4231A mixer anymore, so the code is
+ *        working again, and other small changes to fit in todays
+ *        kernels.
+ *   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,
+ *        added (OSS-limited) equalizer support, return value bugfix,
+ *        changed param aci_reset to reset, new params: ide, wss.
+ *   2001-04-20  Robert Siemer
+ *        even more cleanups...
+ *   2001-10-08  Arnaldo Carvalho de Melo <acme@conectiva.com.br>

+ *	
+ *	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

+ *	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.

+<jsm> tausq: Anyway, to set up sample rates for D to A, you just use the sample rate on the codec. For A to D, you need to set the codec always to 48K (using the split sample rate feature on the codec) and then set the resampler on the AD1889 to the sample rate you want.
+<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  ali5455 and friends ICH driver for Linux
+ *	LEI HU <Lei_Hu@ali.com.tw>
+ *
+ *  Built from:
+ *	drivers/sound/i810_audio
+ *
+ *  	The ALi 5455 is similar but not quite identical to the Intel ICH
+ *	series of controllers. Its easier to keep the driver separated from
+ *	the i810 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
+ *

+ *                of read/write methods [stevel].
+ *    03.21.2002  Add support for coherent DMA on the audio read/write DMA

+ * 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)

+ * 
+ *   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

+*
+* 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 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.

+ *		Thanks to David Pollard for testing.
+ *
+ *	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.

+ *
+ * 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!

+ *  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
+ */

+   When DEAD status is first reported the content of the faulted dbdma block is
+   copied into the emergency buffer and we note that the buffer is in use.
+   we then bump the start physical address by the amount that was successfully
+   output before it died.
+   On any subsequent DEAD result we just do the bump-ups (we know that we are
+   already using the emergency dbdma_cmd).
+   CHECK: this just tries to "do it".  It is possible that we should abandon
+   xfers when the number of residual bytes gets below a certain value - I can
+   see that this might cause a loop-forever if too small a transfer causes
+   DEAD status.  However this is a TODO for now - we'll see what gets reported.
+   When we get a successful transfer result with the emergency buffer we just
+   pretend that it completed using the original dmdma_cmd and carry on.  The
+   'next_cmd' field will already point back to the original loop of blocks.

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

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

+     To over come this, samples are copied into the tram and a special dsp patch copies

+     (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

+ *    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

+ *
+ * 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>

+ *                       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;

+ *
+ *  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
+ *                       Integrated (aka redid 8-)) APM support patch by Zach Brown
+ *    07.02.2000   0.13  Use pci_alloc_consistent and pci_register_driver
+ *    19.02.2000   0.14  Use pci_dma_supported to determine if recording should be disabled
+ *    13.03.2000   0.15  Reintroduce initialization of a couple of PCI config space registers
+ *    21.11.2000   0.16  Initialize dma buffers in poll, otherwise poll may return a bogus mask
+ *    12.12.2000   0.17  More dma buffer initializations, patch from
+ *                       Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
+ *    31.01.2001   0.18  Register/Unregister gameport, original patch from
+ *                       Nathaniel Daw <daw@cs.cmu.edu>
+ *                       Fix SETTRIGGER non OSS API conformity
+ *    10.03.2001         provide abs function, prevent picking up a bogus kernel macro
+ *                       for abs. Bug report by Andrew Morton <andrewm@uow.edu.au>
+ *    15.05.2001         pci_enable_device moved, return values in probe cleaned
+ *                       up. Marcus Meissner <mm@caldera.de>
+ *    22.05.2001   0.19  more cleanups, changed PM to PCI 2.4 style, got rid
+ *                       of global list of devices, using pci device data.
+ *                       Marcus Meissner <mm@caldera.de>
+ *    03.01.2003   0.20  open_mode fixes from Georg Acher <acher@in.tum.de>

+
+	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.

+ *
+ *
+ *	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.
+ *

+ * 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)

+ *
+ * Initialization code for OPTi MAD16 compatible audio chips. Including
+ *
+ *      OPTi 82C928     MAD16           (replaced by C929)
+ *      OAK OTI-601D    Mozart
+ *      OAK OTI-605	Mozart		(later version with MPU401 Midi)
+ *      OPTi 82C929     MAD16 Pro
+ *      OPTi 82C930
+ *      OPTi 82C924
+ *
+ * These audio interface chips don't produce sound themselves. They just
+ * connect some other components (OPL-[234] and a WSS compatible codec)
+ * to the PC bus and perform I/O, DMA and IRQ address decoding. There is
+ * also a UART for the MPU-401 mode (not 82C928/Mozart).
+ * The Mozart chip appears to be compatible with the 82C928, although later
+ * issues of the card, using the OTI-605 chip, have an MPU-401 compatible Midi
+ * port. This port is configured differently to that of the OPTi audio chips.
+ *
+ *	Changes
+ *	
+ *	Alan Cox		Clean up, added module selections.
+ *
+ *	A. Wik			Added support for Opti924 PnP.
+ *				Improved debugging support.	16-May-1998
+ *				Fixed bug.			16-Jun-1998
+ *
+ *      Torsten Duwe            Made Opti924 PnP support non-destructive
+ *                                                             	23-Dec-1998
+ *
+ *	Paul Grayson		Added support for Midi on later Mozart cards.
+ *								25-Nov-1999
+ *	Christoph Hellwig	Adapted to module_init/module_exit.
+ *	Arnaldo C. de Melo	got rid of attach_uart401       21-Sep-2000
+ *

+ *
+ *  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
+ *  (still kind of v0.14) Nov 23 - Alan Cox <alan@redhat.com>
+ *	Add clocking= for people with seriously warped hardware
+ *  (still v0.14) Nov 10 2000 - Bartlomiej Zolnierkiewicz <bkz@linux-ide.org>
+ *	add __init to maestro_ac97_init() and maestro_install()
+ *  (still based on v0.14) Mar 29 2000 - Zach Brown <zab@redhat.com>
+ *	move to 2.3 power management interface, which
+ *		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.
+ *	we now shut down on machine reboot/halt
+ *	leave scary PCI config items alone (isa stuff, mostly)
+ *	enable 1921s, it seems only mine was broke.
+ *	fix swapped left/right pcm dac.  har har.
+ *	up bob freq, increase buffers, fix pointers at underflow
+ *	silly compilation problems
+ *  v0.13 - Nov 18 1999 - Zach Brown <zab@redhat.com>
+ *	fix nec Versas?  man would that be cool.
+ *  v0.12 - Nov 12 1999 - Zach Brown <zab@redhat.com>
+ *	brown bag volume max fix..
+ *  v0.11 - Nov 11 1999 - Zach Brown <zab@redhat.com>
+ *	use proper stereo apu decoding, mmap/write should work.
+ *	make volume sliders more useful, tweak rate calculation.
+ *	fix lame 8bit format reporting bug.  duh. apm apu saving buglet also
+ *	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>
+ *	added APM support.
+ *	re-order something such that some 2Es now work.  Magic!
+ *	new codec reset routine.  made some codecs come to life.
+ *	fix clear_advance, sync some control with ESS.
+ *	now write to all base regs to be paranoid.
+ *  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?
+ *	fix ess 1921 codec bug on some laptops.
+ *	fix dumb pci scanning bug
+ *	started 2.3 cleanup, redid spinlocks, little cleanups
+ *  v0.06 - Sep 20 1999 - Zach Brown <zab@redhat.com>
+ *	fix wavecache thinkos.  limit to 1 /dev/dsp.
+ *	eric is wearing his thinking toque this week.
+ *		spotted apu mode bugs and gain ramping problem
+ *	don't touch weird mixer regs, make recmask optional
+ *	fixed igain inversion, defaults for mixers, clean up rec_start
+ *	make mono recording work.
+ *	report subsystem stuff, please send reports.
+ *	littles: parallel out, amp now
+ *  v0.05 - Sep 17 1999 - Zach Brown <zab@redhat.com>
+ *	merged and fixed up Eric's initial recording code
+ *	munged format handling to catch misuse, needs rewrite.
+ *	revert ring bus init, fixup shared int, add pci busmaster setting
+ *	fix mixer oss interface, fix mic mute and recmask
+ *	mask off unsupported mixers, reset with all 1s, modularize defaults
+ *	make sure bob is running while we need it
+ *	got rid of device limit, initial minimal apm hooks
+ *	pull out dead code/includes, only allow multimedia/audio maestros
+ *  v0.04 - Sep 01 1999 - Zach Brown <zab@redhat.com>
+ *	copied memory leak fix from sonicvibes driver
+ *	different ac97 reset, play with 2.0 ac97, simplify ring bus setup
+ *	bob freq code, region sanity, jitter sync fix; all from Eric 
+ *
+ * TODO
+ *	fix bob frequency
+ *	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.

+ *	. 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:

+ *     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.
+ *  3. The following is not supported:
+ *      * I2S input.
+ *      * legacy audio mode.
+ *  4. Support for volume button interrupts is implemented but doesn't
+ *     work yet.
+ *
+ *  Revision history
+ *    02.08.2001  0.1   Initial release

+ *	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.

+ *
+ * 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

+ *
+ * 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

+
+
+
+   *  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

+ *
+ * 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.

+ *      June 6 2002 Lei Hu <Lei_hu@ali.com.tw>
+ *      rewrite the part to read/write registers of audio codec for Ali5451 
+ *  v0.14.9e

+ * Locking Notes
+ *
+ *	INC_USE_COUNT and DEC_USE_COUNT keep track of the number of
+ *	open descriptors to this driver. They store it in vwsnd_use_count.
+ * 	The global device list, vwsnd_dev_list,	is immutable when the IN_USE
+ *	is true.
+ *
+ *	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:

+/* High Level Lithium Access */
+
+/*
+ * 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
+ *

+potentially > 0x7F (127) must be split across multiple bytes.
+
+Sometimes, we need to munge numeric values that are represented on
+the x86 side as 8-32 bit values. Sometimes, we need to munge data
+that is represented on the x86 side as an array of bytes. The most
+efficient approach to handling both cases seems to be to use 2
+different functions for munging and 2 for de-munging. This avoids
+weird casting and worrying about bit-level offsets.

+/*
+ * 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.

+ *  card-als4000.c - driver for Avance Logic ALS4000 based soundcards.
+ *  Copyright (C) 2000 by Bart Hartgers <bart@etpmod.phys.tue.nl>,
+ *			  Jaroslav Kysela <perex@suse.cz>
+ *  Copyright (C) 2002 by Andreas Mohr <hw7oshyuv3001@sneakemail.com>
+ *
+ *  Framework borrowed from Massimo Piccioni's card-als100.c.
+ *
+ * NOTES
+ *
+ *  Since Avance does not provide any meaningful documentation, and I
+ *  bought an ALS4000 based soundcard, I was forced to base this driver
+ *  on reverse engineering.
+ *
+ *  Note: this is no longer true. Pretty verbose chip docu (ALS4000a.PDF)
+ *  can be found on the ALSA web site.
+ *
+ *  The ALS4000 seems to be the PCI-cousin of the ALS100. It contains an
+ *  ALS100-like SB DSP/mixer, an OPL3 synth, a MPU401 and a gameport 
+ *  interface. These subsystems can be mapped into ISA io-port space, 
+ *  using the PCI-interface. In addition, the PCI-bit provides DMA and IRQ 
+ *  services to the subsystems.
+ * 
+ * While ALS4000 is very similar to a SoundBlaster, the differences in
+ * DMA and capturing require more changes to the SoundBlaster than
+ * desirable, so I made this separate driver.
+ * 
+ * The ALS4000 can do real full duplex playback/capture.
+ *
+ * FMDAC:
+ * - 0x4f -> port 0x14
+ * - port 0x15 |= 1
+ *
+ * Enable/disable 3D sound:
+ * - 0x50 -> port 0x14
+ * - change bit 6 (0x40) of port 0x15
+ *
+ * Set QSound:
+ * - 0xdb -> port 0x14
+ * - set port 0x15:
+ *   0x3e (mode 3), 0x3c (mode 2), 0x3a (mode 1), 0x38 (mode 0)
+ *
+ * Set KSound:
+ * - value -> some port 0x0c0d

+    Vortex core low level functions.
+	
+ Author: Manuel Jander (mjander@users.sourceforge.cl)
+ These functions are mainly the result of translations made
+ from the original disassembly of the au88x0 binary drivers,
+ written by Aureal before they went down.
+ Many thanks to the Jeff Muizelaar, Kester Maddock, and whoever
+ contributed to the OpenVortex project.
+ The author of this file, put the few available pieces together
+ and translated the rest of the riddle (Mix, Src and connection stuff).
+ Some things are still to be discovered, and their meanings are unclear.
+
+ Some of these functions aren't intended to be really used, rather
+ to help to understand how does the AU88X0 chips work. Keep them in, because
+ they could be used somewhere in the future.
+
+ This code hasn't been tested or proof read thoroughly. If you wanna help,
+ take a look at the AU88X0 assembly and check if this matches.
+ Functions tested ok so far are (they show the desired effect
+ at least):
+   vortex_routes(); (1 bug fixed).
+   vortex_adb_addroute();
+   vortex_adb_addroutes();
+   vortex_connect_codecplay();
+   vortex_src_flushbuffers();
+   vortex_adbdma_setmode();  note: still some unknown arguments!
+   vortex_adbdma_startfifo();
+   vortex_adbdma_stopfifo();
+   vortex_fifo_setadbctrl(); note: still some unknown arguments!
+   vortex_mix_setinputvolumebyte();
+   vortex_mix_enableinput();
+   vortex_mixer_addWTD(); (fixed)
+   vortex_connection_adbdma_src_src();
+   vortex_connection_adbdma_src();
+   vortex_src_change_convratio();
+   vortex_src_addWTD(); (fixed)
+
+ History:
+
+ 01-03-2003 First revision.
+ 01-21-2003 Some bug fixes.
+ 17-02-2003 many bugfixes after a big versioning mess.
+ 18-02-2003 JAAAAAHHHUUUUUU!!!! The mixer works !! I'm just so happy !
+			 (2 hours later...) I cant believe it! Im really lucky today.
+			 Now the SRC is working too! Yeah! XMMS works !
+ 20-02-2003 First steps into the ALSA world.
+ 28-02-2003 As my birthday present, i discovered how the DMA buffer pages really
+            work :-). It was all wrong.
+ 12-03-2003 ALSA driver starts working (2 channels).
+ 16-03-2003 More srcblock_setupchannel discoveries.
+ 12-04-2003 AU8830 playback support. Recording in the works.
+ 17-04-2003 vortex_route() and vortex_routes() bug fixes. AU8830 recording
+ 			works now, but chipn' dale effect is still there.
+ 16-05-2003 SrcSetupChannel cleanup. Moved the Src setup stuff entirely
+            into au88x0_pcm.c .
+ 06-06-2003 Buffer shifter bugfix. Mixer volume fix.
+ 07-12-2003 A3D routing finally fixed. Believed to be OK.
+ 25-03-2004 Many thanks to Claudia, for such valuable bug reports.

+ *  Copyright (C) 2002 by Andreas Mohr <hw7oshyuv3001@sneakemail.com>
+ *
+ *  Framework borrowed from Bart Hartgers's als4000.c.
+ *  Driver developed on PCI168 AP(W) version (PCI rev. 10, subsystem ID 1801),
+ *  found in a Fujitsu-Siemens PC ("Cordant", aluminum case).
+ *  Other versions are:
+ *  PCI168 A(W), sub ID 1800
+ *  PCI168 A/AP, sub ID 8000
+ *  Please give me feedback in case you try my driver with one of these!!

+ *
+ * NOTES
+ *  Since Aztech does not provide any chipset documentation,
+ *  even on repeated request to various addresses,
+ *  and the answer that was finally given was negative
+ *  (and I was stupid enough to manage to get hold of a PCI168 soundcard
+ *  in the first place >:-P}),
+ *  I was forced to base this driver on reverse engineering
+ *  (3 weeks' worth of evenings filled with driver work).
+ *  (and no, I did NOT go the easy way: to pick up a PCI128 for 9 Euros)
+ *
+ *  The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
+ *  for compatibility reasons) has the following features:
+ *
+ *  - builtin AC97 conformant codec (SNR over 80dB)
+ *    (really AC97 compliant?? I really doubt it when looking
+ *    at the mixer register layout)
+ *  - builtin genuine OPL3
+ *  - full duplex 16bit playback/record at independent sampling rate
+ *  - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
+ *  - game port (legacy address support)
+ *  - built-in General DirectX timer having a 20 bits counter
+ *    with 1us resolution (FIXME: where is it?)
+ *  - I2S serial port for external DAC
+ *  - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI
+ *  - supports hardware volume control
+ *  - single chip low cost solution (128 pin QFP)
+ *  - supports programmable Sub-vendor and Sub-system ID
+ *    required for Microsoft's logo compliance (FIXME: where?)
+ *  - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
+ *
+ *  Certain PCI versions of this card are susceptible to DMA traffic underruns
+ *  in some systems (resulting in sound crackling/clicking/popping),
+ *  probably because they don't have a DMA FIFO buffer or so.
+ *  Overview (PCI ID/PCI subID/PCI rev.):
+ *  - no DMA crackling on SiS735: 0x50DC/0x1801/16
+ *  - unknown performance: 0x50DC/0x1801/10
+ *  
+ *  Crackling happens with VIA chipsets or, in my case, an SiS735, which is
+ *  supposed to be very fast and supposed to get rid of crackling much
+ *  better than a VIA, yet ironically I still get crackling, like many other
+ *  people with the same chipset.
+ *  Possible remedies:
+ *  - plug card into a different PCI slot, preferrably one that isn't shared
+ *    too much (this helps a lot, but not completely!)
+ *  - get rid of PCI VGA card, use AGP instead
+ *  - upgrade or downgrade BIOS
+ *  - fiddle with PCI latency settings (setpci -v -s BUSID latency_timer=XX)
+ *    Not too helpful.
+ *  - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
+ * 
+ * BUGS
+ *  - when Ctrl-C'ing mpg321, the playback loops a bit
+ *    (premature DMA playback reset?)
+ *  - full-duplex sometimes breaks (IRQ management issues?).
+ *    Once even a spontaneous REBOOT happened!!!
+ * 
+ * TODO
+ *  - test MPU401 MIDI playback etc.
+ *  - power management (CONFIG_PM). See e.g. intel8x0 or cs4281.
+ *    This would be nice since the chip runs a bit hot, and it's *required*
+ *    anyway for proper ACPI power management. In other words: rest
+ *    assured that I *will* implement this very soon; as soon as Linux 2.5.x
+ *    has power management that's bugfree enough to work properly on my desktop.
+ *  - figure out what all unknown port bits are responsible for

+ *  Copyright (c) 2004 James Courtier-Dutton <James@superbug.demon.co.uk>
+ *  Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
+ *  Version: 0.0.22
+ *
+ *  FEATURES currently supported:
+ *    Front, Rear and Center/LFE.
+ *    Surround40 and Surround51.
+ *    Capture from MIC an LINE IN input.
+ *    SPDIF digital playback of PCM stereo and AC3/DTS works.
+ *    (One can use a standard mono mini-jack to one RCA plugs cable.
+ *     or one can use a standard stereo mini-jack to two RCA plugs cable.
+ *     Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
+ *    ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
+ *    Notes on how to capture sound:
+ *      The AC97 is used in the PLAYBACK direction.
+ *      The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
+ *      So, to record from the MIC, set the MIC Playback volume to max,
+ *      unmute the MIC and turn up the MASTER Playback volume.
+ *      So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
+ *   
+ *    The only playback controls that currently do anything are: -
+ *    Analog Front
+ *    Analog Rear
+ *    Analog Center/LFE
+ *    SPDIF Front
+ *    SPDIF Rear
+ *    SPDIF Center/LFE
+ *   
+ *    For capture from Mic in or Line in.
+ *    Digital/Analog ( switch must be in Analog mode for CAPTURE. )
+ * 
+ *    CAPTURE feedback into PLAYBACK
+ *

+ *    Support interrupts per period.
+ *    Removed noise from Center/LFE channel when in Analog mode.

+ *                   Cirrus Logic, Inc.
+ *  Routines for control of Cirrus Logic CS461x chips
+ *
+ *  KNOWN BUGS:
+ *    - Sometimes the SPDIF input DSP tasks get's unsynchronized
+ *      and the SPDIF get somewhat "distorcionated", or/and left right channel
+ *      are swapped. To get around this problem when it happens, mute and unmute 
+ *      the SPDIF input mixer controll.
+ *    - On the Hercules Game Theater XP the amplifier are sometimes turned
+ *      off on inadecuate moments which causes distorcions on sound.
+ *
+ *  TODO:
+ *    - Secondary CODEC on some soundcards
+ *    - SPDIF input support for other sample rates then 48khz
+ *    - Posibility to mix the SPDIF output with analog sources.
+ *    - PCM channels for Center and LFE on secondary codec
+ *
+ *  NOTE: with CONFIG_SND_CS46XX_NEW_DSP unset uses old DSP image (which
+ *        is default configuration), no SPDIF, no secondary codec, no
+ *        multi channel PCM.  But known to work.
+ *
+ *  FINALLY: A credit to the developers Tom and Jordan 
+ *           at Cirrus for have helping me out with the DSP, however we
+ *           still don't have sufficient documentation and technical
+ *           references to be able to implement all fancy feutures
+ *           supported by the cs46xx DSP's.

+// The purpose of this code is very simple: make it possible to tranfser
+// the samples 'as they are' with no alteration from a PCMreader SCB (DMA from host)
+// to any other SCB. This is useful for AC3 throug SPDIF. SRC (source rate converters) 
+// task always alters the samples in some how, however it's from 48khz -> 48khz. The
+// alterations are not audible, but AC3 wont work.

+ *  Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
+ *  Driver p16v chips
+ *  Version: 0.22
+ *
+ *  FEATURES currently supported:
+ *    Output fixed at S32_LE, 2 channel to hw:0,0
+ *    Rates: 44.1, 48, 96, 192.
+ *
+ *  Changelog:
+ *  0.8
+ *    Use separate card based buffer for periods table.
+ *  0.9
+ *    Use 2 channel output streams instead of 8 channel.
+ *       (8 channel output streams might be good for ASIO type output)
+ *    Corrected speaker output, so Front -> Front etc.
+ *  0.10
+ *    Fixed missed interrupts.
+ *  0.11
+ *    Add Sound card model number and names.
+ *    Add Analog volume controls.
+ *  0.12
+ *    Corrected playback interrupts. Now interrupt per period, instead of half period.
+ *  0.13
+ *    Use single trigger for multichannel.
+ *  0.14
+ *    Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
+ *  0.15
+ *    Force buffer_size / period_size == INTEGER.
+ *  0.16
+ *    Update p16v.c to work with changed alsa api.
+ *  0.17
+ *    Update p16v.c to work with changed alsa api. Removed boot_devs.
+ *  0.18
+ *    Merging with snd-emu10k1 driver.
+ *  0.19
+ *    One stereo channel at 24bit now works.
+ *  0.20
+ *    Added better register defines.
+ *  0.21
+ *    Integrated with snd-emu10k1 driver.
+ *  0.22
+ *    Removed #if 0 ... #endif
+ *
+ *
+ *  BUGS:
+ *    Some stability problems when unloading the snd-p16v kernel module.
+ *    --
+ *
+ *  TODO:
+ *    SPDIF out.
+ *    Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
+ *    Currently capture fixed at 48000Hz.
+ *
+ *    --
+ *  GENERAL INFO:
+ *    Model: SB0240

+ *  Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
+ *  Driver p16v chips
+ *  Version: 0.21
+ *
+ *  FEATURES currently supported:
+ *    Output fixed at S32_LE, 2 channel to hw:0,0
+ *    Rates: 44.1, 48, 96, 192.
+ *
+ *  Changelog:
+ *  0.8
+ *    Use separate card based buffer for periods table.
+ *  0.9
+ *    Use 2 channel output streams instead of 8 channel.
+ *       (8 channel output streams might be good for ASIO type output)
+ *    Corrected speaker output, so Front -> Front etc.
+ *  0.10
+ *    Fixed missed interrupts.
+ *  0.11
+ *    Add Sound card model number and names.
+ *    Add Analog volume controls.
+ *  0.12
+ *    Corrected playback interrupts. Now interrupt per period, instead of half period.
+ *  0.13
+ *    Use single trigger for multichannel.
+ *  0.14
+ *    Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
+ *  0.15
+ *    Force buffer_size / period_size == INTEGER.
+ *  0.16
+ *    Update p16v.c to work with changed alsa api.
+ *  0.17
+ *    Update p16v.c to work with changed alsa api. Removed boot_devs.
+ *  0.18
+ *    Merging with snd-emu10k1 driver.
+ *  0.19
+ *    One stereo channel at 24bit now works.
+ *  0.20
+ *    Added better register defines.
+ *  0.21
+ *    Split from p16v.c
+ *
+ *
+ *  BUGS:
+ *    Some stability problems when unloading the snd-p16v kernel module.
+ *    --
+ *
+ *  TODO:
+ *    SPDIF out.
+ *    Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
+ *    Currently capture fixed at 48000Hz.

+  NOTES:
+  - Capture data is written unaligned starting from dma_base + 1 so I need to
+    disable mmap and to add a copy callback.
+  - After several cycle of the following:
+    while : ; do arecord -d1 -f cd -t raw | aplay -f cd ; done
+    a "playback write error (DMA or IRQ trouble?)" may happen.
+    This is due to playback interrupts not generated.
+    I suspect a timing issue.
+  - Sometimes the interrupt handler is invoked wrongly during playback.
+    This generates some harmless "Unexpected hw_pointer: wrong interrupt
+    acknowledge".
+    I've seen that using small period sizes.
+    Reproducible with:
+    mpg123 test.mp3 &
+    hdparm -t -T /dev/hda

+ *
+ *  Notes from Zach Brown about the driver code
+ *
+ *  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.

+ * - we reuse the akm4xxx_t record for storing the wm8770 codec data.
+ *   both wm and akm codecs are pretty similar, so we can integrate

+ *   many boards.
+ *
+ * - DAC digital volumes are not implemented in the mixer.
+ *   if they show better response than DAC analog volumes, we can use them
+ *   instead.
+ *
+ *   Lowlevel functions for AudioTrak Prodigy 7.1 (and possibly 192) cards
+ *      Copyright (c) 2003 Dimitromanolakis Apostolos <apostol@cs.utoronto.ca>
+ *
+ *   version 0.82: Stable / not all features work yet (no communication with AC97 secondary)
+ *       added 64x/128x oversampling switch (should be 64x only for 96khz)
+ *       fixed some recording labels (still need to check the rest)
+ *       recording is working probably thanks to correct wm8770 initialization
+ *
+ *   version 0.5: Initial release:
+ *           working: analog output, mixer, headphone amplifier switch
+ *       not working: prety much everything else, at least i could verify that
+ *                    we have no digital output, no capture, pretty bad clicks and poops
+ *                    on mixer switch and other coll stuff.

+ * Changes:
+ *
+ *  2002.09.09	Takashi Iwai <tiwai@suse.de>
+ *	split the code to several files.  each low-level routine
+ *	is stored in the local file and called from registration
+ *	function from card_info struct.
+ *
+ *  2002.11.26	James Stafford <jstafford@ampltd.com>
+ *	Added support for VT1724 (Envy24HT)
+ *	I have left out support for 176.4 and 192 KHz for the moment. 
+ *  I also haven't done anything with the internal S/PDIF transmitter or the MPU-401
+ *
+ *  2003.02.20  Taksahi Iwai <tiwai@suse.de>
+ *	Split vt1724 part to an independent driver.
+ *	The GPIO is accessed through the callback functions now.
+ *
+ * 2004.03.31 Doug McLain <nostar@comcast.net>
+ *    Added support for Event Electronics EZ8 card to hoontech.c.

+ * Note #1 "Sek'd models" ................................... martin 2002-12-07
+ * 
+ * Identical soundcards by Sek'd were labeled:
+ * RME Digi 32     = Sek'd Prodif 32
+ * RME Digi 32 Pro = Sek'd Prodif 96
+ * RME Digi 32/8   = Sek'd Prodif Gold
+ * 
+ * ****************************************************************************
+ * 
+ * Note #2 "full duplex mode" ............................... martin 2002-12-07
+ * 
+ * Full duplex doesn't work. All cards (32, 32/8, 32Pro) are working identical
+ * in this mode. Rec data and play data are using the same buffer therefore. At
+ * first you have got the playing bits in the buffer and then (after playing
+ * them) they were overwitten by the captured sound of the CS8412/14. Both 
+ * modes (play/record) are running harmonically hand in hand in the same buffer
+ * and you have only one start bit plus one interrupt bit to control this 
+ * paired action.
+ * This is opposite to the latter rme96 where playing and capturing is totally
+ * separated and so their full duplex mode is supported by alsa (using two 
+ * start bits and two interrupts for two different buffers). 
+ * But due to the wrong sequence of playing and capturing ALSA shows no solved
+ * full duplex support for the rme32 at the moment. That's bad, but I'm not
+ * able to solve it. Are you motivated enough to solve this problem now? Your
+ * patch would be welcome!
+ * 
+ * ****************************************************************************
+ *
+ * "The story after the long seeking" -- tiwai
+ *
+ * Ok, the situation regarding the full duplex is now improved a bit.
+ * In the fullduplex mode (given by the module parameter), the hardware buffer
+ * is split to halves for read and write directions at the DMA pointer.
+ * That is, the half above the current DMA pointer is used for write, and
+ * the half below is used for read.  To mangle this strange behavior, an
+ * software intermediate buffer is introduced.  This is, of course, not good
+ * from the viewpoint of the data transfer efficiency.  However, this allows
+ * you to use arbitrary buffer sizes, instead of the fixed I/O buffer size.
+ *

+ * [0,8192] to a logarithmic attenuation value in the range 0 to 6.02dB.
+ * Halving the linear volume is equivalent to an additional 6dB of 
+ * logarithmic attenuation. The algorithm used in log_from_linear()
+ * therefore uses this table as follows:
+ * 
+ * - loop and for every time the volume is less than half the maximum 
+ *   volume (16384), add another 6dB and halve the maximum value used
+ *   for this comparison.
+ * - when the volume is greater than half the maximum volume, take
+ *   the difference of the volume to half volume (in the range [0,8192])
+ *   and look up the log_table[] to find the nearest entry.
+ * - take the logarithic component of this entry and add it to the 
+ *   resulting attenuation.
+ *
+ * Thus this routine provides a linear->log conversion for a range of
+ * [0,16384] using only 386 table entries
+ *
+ * Note: although this table stores log attenuation in 8.8 format, values
+ * were only calculated for 6 bits fractional precision, since that is

+ * Changes:
+ *
+ * Dec. 19, 2002	Takashi Iwai <tiwai@suse.de>
+ *	- use the DSX channels for the first pcm playback.
+ *	  (on VIA8233, 8233C and 8235 only)
+ *	  this will allow you play simultaneously up to 4 streams.
+ *	  multi-channel playback is assigned to the second device
+ *	  on these chips.
+ *	- support the secondary capture (on VIA8233/C,8235)
+ *	- SPDIF support
+ *	  the DSX3 channel can be used for SPDIF output.
+ *	  on VIA8233A, this channel is assigned to the second pcm
+ *	  playback.
+ *	  the card config of alsa-lib will assign the correct
+ *	  device for applications.
+ *	- clean up the code, separate low-level initialization
+ *	  routines for each chipset.

+ *	Sound core handling. Breaks out sound functions to submodules

+ *                         --------------------
+ * 
+ *	Top level handler for the sound subsystem. Various devices can
+ *	plug into this. The fact they don't all go via OSS doesn't mean 
+ *	they don't have to implement the OSS API. There is a lot of logic
+ *	to keeping much of the OSS weight out of the code in a compatibility
+ *	module, but it's up to the driver to rember to load it...
+ *
+ *	The code provides a set of functions for registration of devices
+ *	by type. This is done rather than providing a single call so that
+ *	we can hide any future changes in the internals (eg when we go to
+ *	32bit dev_t) from the modules and their interface.
+ *
+ *	Secondly we need to allocate the dsp, dsp16 and audio devices as
+ *	one. Thus we misuse the chains a bit to simplify this.
+ *
+ *	Thirdly to make it more fun and for 2.3.x and above we do all
+ *	of this using fine grained locking.
+ *
+ *	FIXME: we have to resolve modules and fine grained load/unload
+ *	locking at some point in 2.3.x.

+ * Driver for AMD7930 sound chips found on Sparcs.
+ * Copyright (C) 2002 David S. Miller <davem@redhat.com>

+ * Copyright (C) 1996,1997 Thomas K. Dyas (tdyas@eden.rutgers.edu)
+ *
+ * --- Notes from Thomas's original driver ---
+ * This is the lowlevel driver for the AMD7930 audio chip found on all
+ * sun4c machines and some sun4m machines.
+ *
+ * The amd7930 is actually an ISDN chip which has a very simple
+ * integrated audio encoder/decoder. When Sun decided on what chip to
+ * use for audio, they had the brilliant idea of using the amd7930 and
+ * only connecting the audio encoder/decoder pins.
+ *
+ * Thanks to the AMD engineer who was able to get us the AMD79C30
+ * databook which has all the programming information and gain tables.
+ *
+ * Advanced Micro Devices' Am79C30A is an ISDN/audio chip used in the
+ * SparcStation 1+.  The chip provides microphone and speaker interfaces
+ * which provide mono-channel audio at 8K samples per second via either
+ * 8-bit A-law or 8-bit mu-law encoding.  Also, the chip features an
+ * ISDN BRI Line Interface Unit (LIU), I.430 S/T physical interface,
+ * which performs basic D channel LAPD processing and provides raw
+ * B channel data.  The digital audio channel, the two ISDN B channels,
+ * and two 64 Kbps channels to the microprocessor are all interconnected
+ * via a multiplexer.

+ *     2.4.22 usb-uhci seems buggy for async unlinking and results in
+ *     oops.  in such a cse, pass async_unlink=0 option.
+ *   - the linked URBs would be preferred but not used so far because of
+ *     the instability of unlinking.
+ *   - type II is not supported properly.  there is no device which supports
+ *     this type *correctly*.  SB extigy looks as if it supports, but it's
+ *     indeed an AC3 stream packed in SPDIF frames (i.e. no real AC3 stream).

+/*
+ * usbusy2y.c - ALSA USB US-428 Driver
+ *
+2004-12-14 Karsten Wiese
+	Version 0.8.7.1:
+	snd_pcm_open for rawusb pcm-devices now returns -EBUSY if called without rawusb's hwdep device being open.
+
+2004-12-02 Karsten Wiese
+	Version 0.8.7:
+	Use macro usb_maxpacket() for portability.
+
+2004-10-26 Karsten Wiese
+	Version 0.8.6:
+	wake_up() process waiting in usX2Y_urbs_start() on error.
+
+2004-10-21 Karsten Wiese
+	Version 0.8.5:
+	nrpacks is runtime or compiletime configurable now with tested values from 1 to 4.
+
+2004-10-03 Karsten Wiese
+	Version 0.8.2:
+	Avoid any possible racing while in prepare callback.
+
+2004-09-30 Karsten Wiese
+	Version 0.8.0:
+	Simplified things and made ohci work again.
+
+2004-09-20 Karsten Wiese
+	Version 0.7.3:
+	Use usb_kill_urb() instead of deprecated (kernel 2.6.9) usb_unlink_urb().
+
+2004-07-13 Karsten Wiese
+	Version 0.7.1:
+	Don't sleep in START/STOP callbacks anymore.
+	us428 channels C/D not handled just for this version, sorry.
+
+2004-06-21 Karsten Wiese
+	Version 0.6.4:
+	Temporarely suspend midi input
+	to sanely call usb_set_interface() when setting format.
+
+2004-06-12 Karsten Wiese
+	Version 0.6.3:
+	Made it thus the following rule is enforced:
+	"All pcm substreams of one usX2Y have to operate at the same rate & format."
+
+2004-04-06 Karsten Wiese
+	Version 0.6.0:
+	Runs on 2.6.5 kernel without any "--with-debug=" things.
+	us224 reported running.
+
+2004-01-14 Karsten Wiese
+	Version 0.5.1:
+	Runs with 2.6.1 kernel.
+
+2003-12-30 Karsten Wiese
+	Version 0.4.1:
+	Fix 24Bit 4Channel capturing for the us428.
+
+2003-11-27 Karsten Wiese, Martin Langer
+	Version 0.4:
+	us122 support.
+	us224 could be tested by uncommenting the sections containing USB_ID_US224
+
+2003-11-03 Karsten Wiese
+	Version 0.3:
+	24Bit support. 
+	"arecord -D hw:1 -c 2 -r 48000 -M -f S24_3LE|aplay -D hw:1 -c 2 -r 48000 -M -f S24_3LE" works.
+
+2003-08-22 Karsten Wiese
+	Version 0.0.8:
+	Removed EZUSB Firmware. First Stage Firmwaredownload is now done by tascam-firmware downloader.
+	See:
+	http://usb-midi-fw.sourceforge.net/tascam-firmware.tar.gz
+
+2003-06-18 Karsten Wiese
+	Version 0.0.5:
+	changed to compile with kernel 2.4.21 and alsa 0.9.4
+
+2002-10-16 Karsten Wiese
+	Version 0.0.4:
+	compiles again with alsa-current.
+	USB_ISO_ASAP not used anymore (most of the time), instead
+	urb->start_frame is calculated here now, some calls inside usb-driver don't need to happen anymore.
+
+	To get the best out of this:
+	Disable APM-support in the kernel as APM-BIOS calls (once each second) hard disable interrupt for many precious milliseconds.
+	This helped me much on my slowish PII 400 & PIII 500.
+	ACPI yet untested but might cause the same bad behaviour.
+	Use a kernel with lowlatency and preemptiv patches applied.
+	To autoload snd-usb-midi append a line 
+		post-install snd-usb-us428 modprobe snd-usb-midi
+	to /etc/modules.conf.
+
+	known problems:
+	sliders, knobs, lights not yet handled except MASTER Volume slider.
+       	"pcm -c 2" doesn't work. "pcm -c 2 -m direct_interleaved" does.
+	KDE3: "Enable full duplex operation" deadlocks.
+
+	
+2002-08-31 Karsten Wiese
+	Version 0.0.3: audio also simplex;
+	simplifying: iso urbs only 1 packet, melted structs.
+	ASYNC_UNLINK not used anymore: no more crashes so far.....
+	for alsa 0.9 rc3.
+
+2002-08-09 Karsten Wiese
+	Version 0.0.2: midi works with snd-usb-midi, audio (only fullduplex now) with i.e. bristol.
+	The firmware has been sniffed from win2k us-428 driver 3.09.

+/* USX2Y "rawusb" aka hwdep_pcm implementation
+
+ Its usb's unableness to atomically handle power of 2 period sized data chuncs
+ at standard samplerates,
+ what led to this part of the usx2y module: 
+ It provides the alsa kernel half of the usx2y-alsa-jack driver pair.
+ The pair uses a hardware dependant alsa-device for mmaped pcm transport.
+ Advantage achieved:
+         The usb_hc moves pcm data from/into memory via DMA.
+         That memory is mmaped by jack's usx2y driver.
+         Jack's usx2y driver is the first/last to read/write pcm data.
+         Read/write is a combination of power of 2 period shaping and
+         float/int conversation.
+         Compared to mainline alsa/jack we leave out power of 2 period shaping inside
+         snd-usb-usx2y which needs memcpy() and additional buffers.
+         As a side effect possible unwanted pcm-data coruption resulting of
+         standard alsa's snd-usb-usx2y period shaping scheme falls away.
+         Result is sane jack operation at buffering schemes down to 128frames,
+         2 periods.
+         plain usx2y alsa mode is able to achieve 64frames, 4periods, but only at the
+         cost of easier triggered i.e. aeolus xruns (128 or 256frames,
+         2periods works but is useless cause of crackling).
+ 
+ This is a first "proof of concept" implementation.
+ Later, funcionalities should migrate to more apropriate places:
+ Userland:
+ - The jackd could mmap its float-pcm buffers directly from alsa-lib.
+ - alsa-lib could provide power of 2 period sized shaping combined with int/float
+   conversation.
+   Currently the usx2y jack driver provides above 2 services.
+ Kernel:
+ - rawusb dma pcm buffer transport should go to snd-usb-lib, so also snd-usb-audio
+   devices can use it.
+   Currently rawusb dma pcm buffer transport (this file) is only available to snd-usb-usx2y.
