+menuconfig SOUND
+	tristate "Sound card support"
+	depends on HAS_IOMEM
+	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+	  outdated but still useful information as well.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.
+
+if SOUND
+
+config SOUND_OSS_CORE
+	bool
+	default n
+
+config SOUND_OSS_CORE_PRECLAIM
+	bool "Preclaim OSS device numbers"
+	depends on SOUND_OSS_CORE
+	default y
+	help
+	  With this option enabled, the kernel will claim all OSS device
+	  numbers if any OSS support (native or emulation) is enabled
+	  whether the respective module is loaded or not and try to load the
+	  appropriate module using sound-slot/service-* and char-major-*
+	  module aliases when one of the device numbers is opened.  With
+	  this option disabled, kernel will only claim actually in-use
+	  device numbers and opening a missing device will generate only the
+	  standard char-major-* aliases.
+
+	  The only visible difference is use of additional module aliases
+	  and whether OSS sound devices appear multiple times in
+	  /proc/devices.  sound-slot/service-* module aliases are scheduled
+	  to be removed (ie. PRECLAIM won't be available) and this option is
+	  to make the transition easier.  This option can be overridden
+	  during boot using the kernel parameter soundcore.preclaim_oss.
+
+	  Disabling this allows alternative OSS implementations.
+
+	  Please read Documentation/feature-removal-schedule.txt for
+	  details.
+
+	  If unsure, say Y.

+ * This is a driver for the pcm3052 codec chip (codenamed Onyx)

+ * The Onyx codec has the following connections (listed by the bit

+ *  1: digital output
+ *  2: line input
+ *  3: microphone input
+ * Note that even though I know of no machine that has for example

+ * all the different cases in the code so that this driver may serve
+ * as a good example of what to do.
+ *
+ * NOTE: This driver assumes that there's at most one chip to be
+ * 	 used with one alsa card, in form of creating all kinds
+ *	 of mixer elements without regard for their existence.
+ *	 But snd-aoa assumes that there's at most one card, so
+ *	 this means you can only have one onyx on a system. This
+ *	 should probably be fixed by changing the assumption of
+ *	 having just a single card on a system, and making the
+ *	 'card' pointer accessible to anyone who needs it instead
+ *	 of hiding it in the aoa_snd_* functions...

+/*
+ * Apple Onboard Audio driver for tas codec
+ *
+ * Copyright 2006 Johannes Berg <johannes@sipsolutions.net>
+ *
+ * GPL v2, can be found in COPYING.
+ *
+ * Open questions:
+ *  - How to distinguish between 3004 and versions?
+ *
+ * FIXMEs:
+ *  - This codec driver doesn't honour the 'connected'
+ *    property of the aoa_codec struct, hence if
+ *    it is used in machines where not everything is
+ *    connected it will display wrong mixer elements.
+ *  - Driver assumes that the microphone is always
+ *    monaureal and connected to the right channel of
+ *    the input. This should also be a codec-dependent
+ *    flag, maybe the codec should have 3 different
+ *    bits for the three different possibilities how
+ *    it can be hooked up...
+ *    But as long as I don't see any hardware hooked
+ *    up that way...
+ *  - As Apple notes in their code, the tas3004 seems
+ *    to delay the right channel by one sample. You can
+ *    see this when for example recording stereo in
+ *    audacity, or recording the tas output via cable
+ *    on another machine (use a sinus generator or so).
+ *    I tried programming the BiQuads but couldn't
+ *    make the delay work, maybe someone can read the
+ *    datasheet and fix it. The relevant Apple comment
+ *    is in AppleTAS3004Audio.cpp lines 1637 ff. Note
+ *    that their comment describing how they program
+ *    the filters sucks...
+ *
+ * Other things:
+ *  - this should actually register *two* aoa_codec
+ *    structs since it has two inputs. Then it must
+ *    use the prepare callback to forbid running the
+ *    secondary output on a different clock.
+ *    Also, whatever bus knows how to do this must
+ *    provide two soundbus_dev devices and the fabric
+ *    must be able to link them correctly.
+ *
+ *    I don't even know if Apple ever uses the second
+ *    port on the tas3004 though, I don't think their
+ *    i2s controllers can even do it. OTOH, they all
+ *    derive the clocks from common clocks, so it
+ *    might just be possible. The framework allows the
+ *    codec to refine the transfer_info items in the
+ *    usable callback, so we can simply remove the
+ *    rates the second instance is not using when it
+ *    actually is in use.
+ *    Maybe we'll need to make the sound busses have
+ *    a 'clock group id' value so the codec can
+ *    determine if the two outputs can be driven at
+ *    the same time. But that is likely overkill, up
+ *    to the fabric to not link them up incorrectly,
+ *    and up to the hardware designer to not wire
+ *    them up in some weird unusable way.

+ * (33 - 8191). The result can be seen in the following encoding table:

+ *	------------------------	---------------

+ *
+ * Each biased linear code has a leading 1 which identifies the segment
+ * number. The value of the segment number is equal to 7 minus the number
+ * of leading 0's. The quantization interval is directly available as the
+ * four bits wxyz.  * The trailing bits (a - h) are ignored.
+ *
+ * Ordinarily the complement of the resulting code word is used for
+ * transmission, and so the code word is complemented before it is returned.

+ * 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 a configuration file under /etc/modprobe.d/:
+
+	option snd-seq-dummy ports=4
+
+  The model 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 struct snd_seq_queue pointer 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.

+ *
+ *  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

+/* 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.
+ *
+ * - Zoom Video is implemented by sharing the FM DAC, thus the user can
+ *   have either FM playback or Video playback but not both simultaneously.
+ *   The Video Playback Switch mixer control toggles this choice.
+ *
+ * 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.
+ *
+ */
+
+/*
+ * ES1879 NOTES:
+ * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
+ *   seems to be effected (speaker_test plays a lower frequency). Can't find
+ *   anything in the datasheet to account for this, so a Video Playback Switch
+ *   control has been included to allow ZV to be enabled only when necessary.
+ *   Then again on at least one test system the 0x71 bit 6 enable bit is not 
+ *   needed for ZV, so maybe the datasheet is entirely wrong here.

+ *	since there is no classic driver for alsa yet (i dont have a classic
+ *	& writing one blindfold is difficult) this file's object is statically
+ *	linked into the pinnacle-driver-module for now.	look for the string
+ *		"uncomment this to make this a module again"
+ *	to do guess what.

+ *  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.

+		   reload of the ICS2115, which is a very expensive operation.
+
+		   So, doing things this way allows us to honor the notion of
+		   "RESETSAMPLES" reasonably cheaply. Note however, that this
+		   is done purely at user level: there is no WFB parser in
+		   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
+		   crazy: we'd need 158K of kernel space just to hold
+		   a copy of the patch/program/sample header data.

+
+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.
+

+	---help---
+	  Linux can often have problems allocating DMA buffers for ISA sound

+	  DMA buffers must exist below the 16MB boundary and it is quite
+	  possible that a large enough free block in this region cannot be
+	  found after the machine has been running for a while. If you say Y
+	  here the DMA buffers (64Kb) will be allocated at boot time and kept
+	  until the shutdown. This option is only useful if you said Y to
+	  "OSS sound modules", above. If you said M to "OSS sound modules"
+	  then you can get the persistent DMA buffer functionality by passing
+	  the command-line argument "dmabuf=1" to the sound module.
+
+	  Say Y unless you have 16MB or more RAM or a PCI sound card.

+	  made by Microsoft or Aztech SG 16 Pro (or NX16 Pro).  Also you may
+	  say Y in case your card is NOT among these:
+

+
+	  For cards having native support in VoxWare, consult the card
+	  specific instructions in <file:Documentation/sound/oss/README.OSS>.
+	  Some drivers have their own MSS support and saying Y to this option
+	  will cause a conflict.
+

+	  all sound cards.  However, some natively supported cards have their
+	  own driver for MPU401.  Enabling this MPU401 option with these cards
+	  will cause a conflict.  Also, enabling MPU401 on a system that
+	  doesn't really have a MPU401 could cause some trouble.  If your card
+	  was in the list of supported cards, look at the card specific
+	  instructions in the <file:Documentation/sound/oss/README.OSS> file.  It
+	  is safe to answer Y if you have a true MPU401 MIDI interface card.
+
+	  If you compile the driver into the kernel, you have to add

+
+config SOUND_PAS
+	tristate "ProAudioSpectrum 16 support"
+	---help---
+	  Answer Y only if you have a Pro Audio Spectrum 16, ProAudio Studio

+	  other card made by Media Vision or Logitech since those are not
+	  PAS16 compatible. Please read <file:Documentation/sound/oss/PAS16>.
+	  It is not necessary to add Sound Blaster support separately; it
+	  is included in PAS support.
+
+	  If you compile the driver into the kernel, you have to add
+	  "pas2=<io>,<irq>,<dma>,<dma2>,<sbio>,<sbirq>,<sbdma>,<sbdma2>
+	  to the kernel command line.

+
+config PSS_MIXER
+	bool "Enable PSS mixer (Beethoven ADSP-16 and other compatible)"

+	  SM Games). For an unknown card you may answer Y if the card claims
+	  to be Sound Blaster-compatible.
+
+	  Please read the file <file:Documentation/sound/oss/Soundblaster>.
+

+	  for cards based on ESS chips (read
+	  <file:Documentation/sound/oss/ESS1868> and

+	  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

+ * sound/oss/ad1848.c
+ *
+ * The low level driver for the AD1848/CS4248 codec chip which
+ * is used for example in the MS Sound System.
+ *
+ * The CS4231 which is used in the GUS MAX and some other cards is
+ * upwards compatible with AD1848 and this driver is able to drive it.
+ *
+ * CS4231A and AD1845 are upward compatible with CS4231. However
+ * the new features of these chips are different.
+ *
+ * CS4232 is a PnP audio chip which contains a CS4231A (and SB, MPU).
+ * CS4232A is an improved version of CS4232.

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

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

+ * Thomas Sailer   : moved several static variables into struct audio_operations
+ *                   (which is grossly misnamed btw.) because they have the same
+ *                   lifetime as the rest in there and dynamic allocation saves
+ *                   12k or so
+ * Thomas Sailer   : remove {in,out}_sleep_flag. It was used for the sleeper to
+ *                   determine if it was woken up by the expiring timeout or by
+ *                   an explicit wake_up. The return value from schedule_timeout
+ *		     can be used instead; if 0, the wakeup was due to the timeout.

+ *
+ * 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!

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

+/* ++TeSche: radically changed for new expanding purposes...
+ *
+ * These two routines now deal with copying/expanding/translating the samples
+ * from user space into our buffer at the right frequency. They take care about
+ * how much data there's actually to read, how much buffer space there is and
+ * to convert samples into the right frequency/encoding. They will only work on
+ * complete samples so it may happen they leave some bytes in the input stream
+ * if the user didn't write a multiple of the current sample size. They both
+ * return the number of bytes they've used from both streams so you may detect
+ * such a situation. Luckily all programs should be able to cope with that.
+ *
+ * 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)

+ * The older version (VSA1) provides fairly good soundblaster emulation

+ * to control the AC97 audio engine directly and requires a different driver.

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

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

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

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

+ * Locking Notes
+ *
+ *	INC_USE_COUNT and DEC_USE_COUNT keep track of the number of

+ * 	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_mutex 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_mutex 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.

+ *
+ *        OUT_O -> Front,
+ *	  OUT_1 -> Surround,
+ *	  OUT_2 -> C/LFE
+ *
+ * Unlike the 1617a, each OUT has a consistent set of mappings
+ * for all bitpatterns other than 00:
+ *
+ *        01       Unmixed Output
+ *        10       Line In
+ *        11       Mic  In
+ *
+ * Special Case of 00:
+ *
+ *        OUT_0    Mixed Output
+ *        OUT_1    Reserved
+ *        OUT_2    Reserved
+ *
+ * I have no idea what the hell Reserved does, but on an MSI
+ * CN700T, i have to set it to get 5.1 output - YMMV, bad
+ * shit may happen.

+ *
+ * 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 (thank you!):
+ *  pretty verbose chip docu (ALS4000a.PDF) can be found on the ALSA web site.
+ *  Page numbers stated anywhere below with the "SPECS_PAGE:" tag
+ *  refer to: ALS4000a.PDF specs Ver 1.0, May 28th, 1998.
+ *
+ *  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
+ *
+ * ToDo:
+ * - by default, don't enable legacy game and use PCI game I/O
+ * - power management? (card can do voice wakeup according to datasheet!!)

+    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, 2005 - 2011 by Andreas Mohr <andi AT lisas.de>
+ *
+ *  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!!
+ *
+ *  Keywords: Windows XP Vista 168nt4-125.zip 168win95-125.zip PCI 168 download
+ *  (XP/Vista do not support this card at all but every Linux distribution
+ *   has very good support out of the box;
+ *   just to make sure that the right people hit this and get to know that,
+ *   despite the high level of Internet ignorance - as usual :-P -

+ *
+ * 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 SB PCI128 for 9 Euros)
+ *
+ *  It is quite likely that the AZF3328 chip is the PCI cousin of the
+ *  AZF3318 ("azt1020 pnp", "MM Pro 16") ISA chip, given very similar specs.
+ *
+ *  The AZF3328 chip (note: AZF3328, *not* AZT3328, that's just the driver name
+ *  for compatibility reasons) from Azfin (joint-venture of Aztech and Fincitec,
+ *  Fincitec acquired by National Semiconductor in 2002, together with the
+ *  Fincitec-related company ARSmikro) has the following features:
+ *
+ *  - compatibility & compliance:
+ *    - Microsoft PC 97 ("PC 97 Hardware Design Guide",
+ *                       http://www.microsoft.com/whdc/archive/pcguides.mspx)
+ *    - Microsoft PC 98 Baseline Audio
+ *    - MPU401 UART
+ *    - Sound Blaster Emulation (DOS Box)
+ *  - builtin AC97 conformant codec (SNR over 80dB)
+ *    Note that "conformant" != "compliant"!! this chip's mixer register layout
+ *    *differs* from the standard AC97 layout:
+ *    they chose to not implement the headphone register (which is not a
+ *    problem since it's merely optional), yet when doing this, they committed
+ *    the grave sin of letting other registers follow immediately instead of
+ *    keeping a headphone dummy register, thereby shifting the mixer register
+ *    addresses illegally. So far unfortunately it looks like the very flexible
+ *    ALSA AC97 support is still not enough to easily compensate for such a
+ *    grave layout violation despite all tweaks and quirks mechanisms it offers.
+ *    Well, not quite: now ac97 layer is much improved (bus-specific ops!),
+ *    thus I was able to implement support - it's actually working quite well.
+ *    An interesting item might be Aztech AMR 2800-W, since it's an AC97
+ *    modem card which might reveal the Aztech-specific codec ID which
+ *    we might want to pretend, too. Dito PCI168's brother, PCI368,
+ *    where the advertising datasheet says it's AC97-based and has a
+ *    Digital Enhanced Game Port.
+ *  - builtin genuine OPL3 - verified to work fine, 20080506
+ *  - full duplex 16bit playback/record at independent sampling rate
+ *  - MPU401 (+ legacy address support, claimed by one official spec sheet)
+ *    FIXME: how to enable legacy addr??
+ *  - game port (legacy address support)
+ *  - builtin DirectInput support, helps reduce CPU overhead (interrupt-driven
+ *    features supported). - See common term "Digital Enhanced Game Port"...
+ *    (probably DirectInput 3.0 spec - confirm)
+ *  - builtin 3D enhancement (said to be YAMAHA Ymersion)
+ *  - built-in General DirectX timer having a 20 bits counter
+ *    with 1us resolution (see below!)
+ *  - I2S serial output port for external DAC
+ *    [FIXME: 3.3V or 5V level? maximum rate is 66.2kHz right?]
+ *  - 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 [24C02 SEEPROM chip]
+ *    required for Microsoft's logo compliance (FIXME: where?)
+ *    At least the Trident 4D Wave DX has one bit somewhere
+ *    to enable writes to PCI subsystem VID registers, that should be it.
+ *    This might easily be in extended PCI reg space, since PCI168 also has
+ *    some custom data starting at 0x80. What kind of config settings
+ *    are located in our extended PCI space anyway??
+ *  - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
+ *    [TDA1517P chip]
+ *
+ *  Note that this driver now is actually *better* than the Windows driver,
+ *  since it additionally supports the card's 1MHz DirectX timer - just try
+ *  the following snd-seq module parameters etc.:
+ *  - options snd-seq seq_default_timer_class=2 seq_default_timer_sclass=0
+ *    seq_default_timer_card=0 seq_client_load=1 seq_default_timer_device=0
+ *    seq_default_timer_subdevice=0 seq_default_timer_resolution=1000000
+ *  - "timidity -iAv -B2,8 -Os -EFreverb=0"
+ *  - "pmidi -p 128:0 jazz.mid"
+ *
+ *  OPL3 hardware playback testing, try something like:
+ *  cat /proc/asound/hwdep
+ *  and
+ *  aconnect -o
+ *  Then use
+ *  sbiload -Dhw:x,y --opl3 /usr/share/sounds/opl3/std.o3 ......./drums.o3
+ *  where x,y is the xx-yy number as given in hwdep.
+ *  Then try
+ *  pmidi -p a:b jazz.mid
+ *  where a:b is the client number plus 0 usually, as given by aconnect above.
+ *  Oh, and make sure to unmute the FM mixer control (doh!)
+ *  NOTE: power use during OPL3 playback is _VERY_ high (70W --> 90W!)
+ *  despite no CPU activity, possibly due to hindering ACPI idling somehow.
+ *  Shouldn't be a problem of the AZF3328 chip itself, I'd hope.
+ *  Higher PCM / FM mixer levels seem to conflict (causes crackling),
+ *  at least sometimes.   Maybe even use with hardware sequencer timer above :)
+ *  adplay/adplug-utils might soon offer hardware-based OPL3 playback, too.
+ *
+ *  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
+ *    (well, it's not bad on an Athlon 1800 with now very optimized IRQ handler)
+ *
+ *  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:
+ *  - use speaker (amplifier) output instead of headphone output
+ *    (in case crackling is due to overloaded output clipping)
+ *  - plug card into a different PCI slot, preferably 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
+ *  - full-duplex might *still* be problematic, however a recent test was fine
+ *  - (non-bug) "Bass/Treble or 3D settings don't work" - they do get evaluated
+ *    if you set PCM output switch to "pre 3D" instead of "post 3D".
+ *    If this can't be set, then get a mixer application that Isn't Stupid (tm)
+ *    (e.g. kmix, gamix) - unfortunately several are!!
+ *  - locking is not entirely clean, especially the audio stream activity
+ *    ints --> may be racy
+ *  - an _unconnected_ secondary joystick at the gameport will be reported
+ *    to be "active" (floating values, not precisely -1) due to the way we need
+ *    to read the Digital Enhanced Game Port. Not sure whether it is fixable.
+ *
+ * TODO
+ *  - use PCI_VDEVICE
+ *  - verify driver status on x86_64
+ *  - test multi-card driver operation
+ *  - (ab)use 1MHz DirectX timer as kernel clocksource
+ *  - test MPU401 MIDI playback etc.
+ *  - add more power micro-management (disable various units of the card
+ *    as long as they're unused, to improve audio quality and save power).
+ *    However this requires more I/O ports which I haven't figured out yet
+ *    and which thus might not even exist...
+ *    The standard suspend/resume functionality could probably make use of
+ *    some improvement, too...
+ *  - figure out what all unknown port bits are responsible for
+ *  - figure out some cleverly evil scheme to possibly make ALSA AC97 code
+ *    fully accept our quite incompatible ""AC97"" mixer and thus save some
+ *    code (but I'm not too optimistic that doing this is possible at all)
+ *  - use MMIO (memory-mapped I/O)? Slightly faster access, e.g. for gameport.

+ *  Copyright (c) 2004 James Courtier-Dutton <James@superbug.demon.co.uk>
+ *  Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
+ *  Version: 0.0.25
+ *
+ *  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
+ * 
+ *  Changelog:
+ *    Support interrupts per period.
+ *    Removed noise from Center/LFE channel when in Analog mode.
+ *    Rename and remove mixer controls.
+ *  0.0.6
+ *    Use separate card based DMA buffer for periods table list.
+ *  0.0.7
+ *    Change remove and rename ctrls into lists.
+ *  0.0.8
+ *    Try to fix capture sources.
+ *  0.0.9
+ *    Fix AC3 output.
+ *    Enable S32_LE format support.
+ *  0.0.10
+ *    Enable playback 48000 and 96000 rates. (Rates other that these do not work, even with "plug:front".)
+ *  0.0.11
+ *    Add Model name recognition.
+ *  0.0.12
+ *    Correct interrupt timing. interrupt at end of period, instead of in the middle of a playback period.
+ *    Remove redundent "voice" handling.
+ *  0.0.13

+ *                   Abramo Bagnara <abramo@alsa-project.org>
+ *                   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 control.
+ *    - 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.

+ *
+ * This driver was ported (shamelessly ripped ;) from oss/kahlua.c but I did
+ * mess with it a bit. The chip seems to have to have trouble with full duplex
+ * mode. If we're recording in 8bit 8000kHz, say, and we then attempt to
+ * simultaneously play back audio at 16bit 44100kHz, the device actually plays
+ * back in the same format in which it is capturing. By forcing the chip to
+ * always play/capture in 16/44100, we can let alsa-lib convert the samples and
+ * that way we can hack up some full duplex audio. 
+ * 
+ * XpressAudio(tm) is used on the Cyrix MediaGX (now NatSemi Geode) systems.
+ * The older version (VSA1) provides fairly good soundblaster emulation
+ * although there are a couple of bugs: large DMA buffers break record,
+ * and the MPU event handling seems suspect. VSA2 allows the native driver
+ * to control the AC97 audio engine directly and requires a different driver.
+ *
+ * Thanks to National Semiconductor for providing the needed information
+ * on the XpressAudio(tm) internals.

+   Here's a block diagram of how most of the cards work:
+
+                  +-----------+
+           record |           |<-------------------- Inputs
+          <-------|           |        |
+     PCI          | Transport |        |
+     bus          |  engine   |       \|/
+          ------->|           |    +-------+
+            play  |           |--->|monitor|-------> Outputs
+                  +-----------+    | mixer |
+                                   +-------+
+
+   The lines going to and from the PCI bus represent "pipes".  A pipe performs
+   audio transport - moving audio data to and from buffers on the host via
+   bus mastering.
+
+   The inputs and outputs on the right represent input and output "busses."
+   A bus is a physical, real connection to the outside world.  An example
+   of a bus would be the 1/4" analog connectors on the back of Layla or
+   an RCA S/PDIF connector.
+
+   For most cards, there is a one-to-one correspondence between outputs
+   and busses; that is, each individual pipe is hard-wired to a single bus.
+
+   Cards that work this way are Darla20, Gina20, Layla20, Darla24, Gina24,
+   Layla24, Mona, and Indigo.
+
+
+   Mia has a feature called "virtual outputs."
+
+
+                  +-----------+
+           record |           |<----------------------------- Inputs
+          <-------|           |                  |
+     PCI          | Transport |                  |
+     bus          |  engine   |                 \|/
+          ------->|           |   +------+   +-------+
+            play  |           |-->|vmixer|-->|monitor|-------> Outputs
+                  +-----------+   +------+   | mixer |
+                                             +-------+
+
+
+   Obviously, the difference here is the box labeled "vmixer."  Vmixer is
+   short for "virtual output mixer."  For Mia, pipes are *not* hard-wired
+   to a single bus; the vmixer lets you mix any pipe to any bus in any
+   combination.
+
+   Note, however, that the left-hand side of the diagram is unchanged.
+   Transport works exactly the same way - the difference is in the mixer stage.
+
+
+   Pipes and busses are numbered starting at zero.
+
+
+
+   Pipe index
+   ==========
+
+   A number of calls in CEchoGals refer to a "pipe index".  A pipe index is
+   a unique number for a pipe that unambiguously refers to a playback or record
+   pipe.  Pipe indices are numbered starting with analog outputs, followed by
+   digital outputs, then analog inputs, then digital inputs.
+
+   Take Gina24 as an example:
+
+   Pipe index
+
+   0-7            Analog outputs (0 .. FirstDigitalBusOut-1)
+   8-15           Digital outputs (FirstDigitalBusOut .. NumBussesOut-1)
+   16-17          Analog inputs
+   18-25          Digital inputs
+
+
+   You get the pipe index by calling CEchoGals::OpenAudio; the other transport
+   functions take the pipe index as a parameter.  If you need a pipe index for
+   some other reason, use the handy Makepipe_index method.
+
+
+   Some calls take a CChannelMask parameter; CChannelMask is a handy way to
+   group pipe indices.
+
+
+
+   Digital mode switch
+   ===================
+
+   Some cards (right now, Gina24, Layla24, and Mona) have a Digital Mode Switch
+   or DMS.  Cards with a DMS can be set to one of three mutually exclusive
+   digital modes: S/PDIF RCA, S/PDIF optical, or ADAT optical.
+
+   This may create some confusion since ADAT optical is 8 channels wide and
+   S/PDIF is only two channels wide.  Gina24, Layla24, and Mona handle this
+   by acting as if they always have 8 digital outs and ins.  If you are in
+   either S/PDIF mode, the last 6 channels don't do anything - data sent
+   out these channels is thrown away and you will always record zeros.
+
+   Note that with Gina24, Layla24, and Mona, sample rates above 50 kHz are
+   only available if you have the card configured for S/PDIF optical or S/PDIF
+   RCA.
+
+
+
+   Double speed mode
+   =================
+
+   Some of the cards support 88.2 kHz and 96 kHz sampling (Darla24, Gina24,
+   Layla24, Mona, Mia, and Indigo).  For these cards, the driver sometimes has
+   to worry about "double speed mode"; double speed mode applies whenever the
+   sampling rate is above 50 kHz.
+
+   For instance, Mona and Layla24 support word clock sync.  However, they
+   actually support two different word clock modes - single speed (below
+   50 kHz) and double speed (above 50 kHz).  The hardware detects if a single
+   or double speed word clock signal is present; the generic code uses that
+   information to determine which mode to use.

+
+Setting the sample rates on Layla24 is somewhat schizophrenic.
+
+For standard rates, it works exactly like Mona and Gina24.  That is, for
+8, 11.025, 16, 22.05, 32, 44.1, 48, 88.2, and 96 kHz, you just set the
+appropriate bits in the control register and write the control register.
+
+In order to support MIDI time code sync (and possibly SMPTE LTC sync in
+the future), Layla24 also has "continuous sample rate mode".  In this mode,
+Layla24 can generate any sample rate between 25 and 50 kHz inclusive, or
+50 to 100 kHz inclusive for double speed mode.
+
+To use continuous mode:
+
+-Set the clock select bits in the control register to 0xe (see the #define
+ below)
+
+-Set double-speed mode if you want to use sample rates above 50 kHz
+
+-Write the control register as you would normally
+
+-Now, you need to set the frequency register. First, you need to determine the
+ value for the frequency register.  This is given by the following formula:
+
+frequency_reg = (LAYLA24_MAGIC_NUMBER / sample_rate) - 2
+
+Note the #define below for the magic number
+
+-Wait for the DSP handshake
+-Write the frequency_reg value to the .SampleRate field of the comm page
+-Send the vector command SET_LAYLA24_FREQUENCY_REG (see vmonkey.h)
+
+Once you have set the control register up for continuous mode, you can just
+write the frequency register to change the sample rate.  This could be
+used for MIDI time code sync. For MTC sync, the control register is set for
+continuous mode.  The driver then just keeps writing the
+SET_LAYLA24_FREQUENCY_REG command.

+ *  Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
+ *  Driver p16v chips
+ *  Version: 0.25
+ *
+ *  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
+ *  0.23
+ *    Implement different capture rates.
+ *  0.24
+ *    Implement different capture source channels.
+ *    e.g. When HD Capture source is set to SPDIF,
+ *    setting HD Capture channel to 0 captures from CDROM digital input.
+ *    setting HD Capture channel to 1 captures from SPDIF in.
+ *  0.25
+ *    Include capture buffer sizes.
+ *
+ *  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.
+ *
+ *    --

+ *  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 struct snd_akm4xxx record for storing the wm8770 codec data.
+ *   both wm and akm codecs are pretty similar, so we can integrate
+ *   both controls in the future, once if wm codecs are reused in
+ *   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.

+ * Juli does not use the standard ICE1724 clock scheme. Juli's ice1724 chip is

+ * multiplier. Actual frequency is set by ice1724 GPIOs hooked to the Xilinx.
+ *
+ * The clock circuitry is supplied by the two ice1724 crystals. This
+ * arrangement allows to generate independent clock signal for AK4114's input
+ * rate detection circuit. As a result, Juli, unlike most other
+ * ice1724+ak4114-based cards, detects spdif input rate correctly.
+ * This fact is applied in the driver, allowing to modify PCM stream rate
+ * parameter according to the actual input rate.
+ *
+ * Juli uses the remaining three stereo-channels of its DAC to optionally
+ * monitor analog input, digital input, and digital output. The corresponding
+ * I2S signals are routed by Xilinx, controlled by GPIOs.
+ *
+ * The master mute is implemented using output muting transistors (GPIO) in
+ * combination with smuting the DAC.
+ *
+ * The card itself has no HW master volume control, implemented using the
+ * vmaster control.

+ *
+ *   Lowlevel functions for AudioTrak Prodigy 192 cards
+ *   Supported IEC958 input from optional MI/ODI/O add-on card.
+ *
+ *   Specifics (SW, HW):
+ *   -------------------
+ *   	* 49.5MHz crystal
+ *   	* SPDIF-OUT on the card:
+ *  	  - coax (through isolation transformer)/toslink supplied by
+ *          74HC04 gates - 3 in parallel
+ *   	  - output switched between on-board CD drive dig-out connector
+ *          and ice1724 SPDTX pin, using 74HC02 NOR gates, controlled
+ *          by GPIO20 (0 = CD dig-out, 1 = SPDTX)
+ *   	* SPDTX goes straight to MI/ODI/O card's SPDIF-OUT coax
+ *
+ *   	* MI/ODI/O card: AK4114 based, used for iec958 input only
+ *   		- toslink input -> RX0
+ *   		- coax input -> RX1
+ *   		- 4wire protocol:
+ *   			AK4114		ICE1724
+ *   			------------------------------
+ * 			CDTO (pin 32) -- GPIO11 pin 86
+ * 			CDTI (pin 33) -- GPIO10 pin 77
+ * 			CCLK (pin 34) -- GPIO9 pin 76
+ * 			CSN  (pin 35) -- GPIO8 pin 75
+ *   		- output data Mode 7 (24bit, I2S, slave)
+ *		- both MCKO1 and MCKO2 of ak4114 are fed to FPGA, which
+ *		  outputs master clock to SPMCLKIN of ice1724.
+ *		  Experimentally I found out that only a combination of
+ *		  OCKS0=1, OCKS1=1 (128fs, 64fs output) and ice1724 -
+ *		  VT1724_MT_I2S_MCLK_128X=0 (256fs input) yields correct
+ *		  sampling rate. That means the the FPGA doubles the
+ *		  MCK01 rate.

+ * 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.
+ *

+/* There are three timing modes for the voices.
+ *
+ * For both playback and capture, when the buffer is one or two periods long,
+ * we use the hardware's built-in Mid-Loop Interrupt and End-Loop Interrupt
+ * to let us know when the periods have ended.
+ *
+ * When performing playback with more than two periods per buffer, we set
+ * the "Stop Sample Offset" and tell the hardware to interrupt us when we
+ * reach it. We then update the offset and continue on until we are
+ * interrupted for the next period.
+ *
+ * Capture channels do not have a SSO, so we allocate a playback channel to
+ * use as a timer for the capture periods. We use the SSO on the playback
+ * channel to clock out virtual periods, and adjust the virtual period length
+ * to maintain synchronization. This algorithm came from the Trident driver.
+ *
+ * FIXME: It'd be nice to make use of some of the synth features in the
+ * hardware, but a woeful lack of documentation is a significant roadblock.

+ * 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.
+ *
+ * Sep. 26, 2005	Karsten Wiese <annabellesgarden@yahoo.de>
+ *	- Optimize position calculation for the 823x chips.

+ *              Even though TDM mode can be as part of I2S DAI, but there

+	 *	e.g. Mic Left can be enabled using bit 7 of MIC_L(0x7) reg
+	 *
+	 * (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register
+	 *	e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5)
+	 *
+	 * Out of these two methods, the one using STANDBY bits is preferred
+	 * way to enable/disable individual blocks. This is because STANDBY
+	 * registers are part of system controller which allows system power
+	 * up/down in a controlled, pop-free manner. Also, as per application
+	 * note of DA7210, STANDBY register bits are only effective if a
+	 * particular IO (or ADC/DAC) is already enabled using enable/disable
+	 * register bits. Keeping these things in mind, current DAPM
+	 * implementation manipulates only STANDBY bits.
+	 *
+	 * Overall implementation can be outlined as below,

+ * ALSA SoC TLV320AIC3X codec driver
+ *
+ * Author:      Vladimir Barinov, <vbarinov@embeddedalley.com>
+ * Copyright:   (C) 2007 MontaVista Software, Inc., <source@mvista.com>
+ *
+ * Based on sound/soc/codecs/wm8753.c by Liam Girdwood
+ *
+ * This program is free software; you can redistribute it and/or modify
+ * it under the terms of the GNU General Public License version 2 as

+ *
+ * Notes:
+ *  The AIC3X is a driver for a low power stereo audio
+ *  codecs aic31, aic32, aic33, aic3007.
+ *
+ *  It supports full aic33 codec functionality.
+ *  The compatibility with aic32, aic31 and aic3007 is as follows:
+ *    aic32/aic3007    |        aic31
+ *  ---------------------------------------
+ *   MONO_LOUT -> N/A  |  MONO_LOUT -> N/A
+ *                     |  IN1L -> LINE1L
+ *                     |  IN1R -> LINE1R
+ *                     |  IN2L -> LINE2L
+ *                     |  IN2R -> LINE2R
+ *                     |  MIC3L/R -> N/A
+ *   truncated internal functionality in
+ *   accordance with documentation
+ *  ---------------------------------------
+ *
+ *  Hence the machine layer should disable unsupported inputs/outputs by
+ *  snd_soc_dapm_disable_pin(codec, "MONO_LOUT"), etc.

+ * Notes:
+ *  The WM8753 is a low power, high quality stereo codec with integrated PCM
+ *  codec designed for portable digital telephony applications.
+ *
+ * Dual DAI:-
+ *
+ * This driver support 2 DAI PCM's. This makes the default PCM available for
+ * HiFi audio (e.g. MP3, ogg) playback/capture and the other PCM available for
+ * voice.
+ *
+ * Please note that the voice PCM can be connected directly to a Bluetooth
+ * codec or GSM modem and thus cannot be read or written to, although it is
+ * available to be configured with snd_hw_params(), etc and kcontrols in the
+ * normal alsa manner.
+ *
+ * Fast DAI switching:-
+ *
+ * The driver can now fast switch between the DAI configurations via a

+ * NOTE:  terminology here is confusing.
+ *
+ *  - This driver supports the "Audio Serial Port" (ASP),
+ *    found on dm6446, dm355, and other DaVinci chips.
+ *
+ *  - But it labels it a "Multi-channel Buffered Serial Port"
+ *    (McBSP) as on older chips like the dm642 ... which was
+ *    backward-compatible, possibly explaining that confusion.
+ *
+ *  - OMAP chips have a controller called McBSP, which is
+ *    incompatible with the DaVinci flavor of McBSP.
+ *
+ *  - Newer DaVinci chips have a controller called McASP,
+ *    incompatible with ASP and with either McBSP.
+ *
+ * In short:  this uses ASP to implement I2S, not McBSP.
+ * And it won't be the only DaVinci implemention of I2S.

+ * The i.MX SSI core has some nasty limitations in AC97 mode. While most
+ * sane processor vendors have a FIFO per AC97 slot, the i.MX has only
+ * one FIFO which combines all valid receive slots. We cannot even select
+ * which slots we want to receive. The WM9712 with which this driver
+ * was developed with always sends GPIO status data in slot 12 which
+ * we receive in our (PCM-) data stream. The only chance we have is to
+ * manually skip this data in the FIQ handler. With sampling rates different
+ * from 48000Hz not every frame has valid receive data, so the ratio
+ * between pcm data and GPIO status data changes. Our FIQ handler is not
+ * able to handle this, hence this driver only works with 48000Hz sampling
+ * rate.
+ * Reading and writing AC97 registers is another challenge. The core
+ * provides us status bits when the read register is updated with *another*
+ * value. When we read the same register two times (and the register still
+ * contains the same value) these status bits are not set. We work
+ * around this by not polling these bits but only wait a fixed delay.

+ * Serial Sound Interface (I2S) support for SH7760/SH7780

+ *
+ *  licensed under the terms outlined in the file COPYING at the root

+ *
+ * dont forget to set IPSEL/OMSEL register bits (in your board code) to
+ * enable SSI output pins!
+ */
+
+/*
+ * LIMITATIONS:
+ *	The SSI unit has only one physical data line, so full duplex is
+ *	impossible.  This can be remedied  on the  SH7760 by  using the
+ *	other SSI unit for recording; however the SH7780 has only 1 SSI
+ *	unit, and its pins are shared with the AC97 unit,  among others.
+ *
+ * FEATURES:
+ *	The SSI features "compressed mode": in this mode it continuously
+ *	streams PCM data over the I2S lines and uses LRCK as a handshake
+ *	signal.  Can be used to send compressed data (AC3/DTS) to a DSP.
+ *	The number of bits sent over the wire in a frame can be adjusted
+ *	and can be independent from the actual sample bit depth. This is
+ *	useful to support TDM mode codecs like the AD1939 which have a
+ *	fixed TDM slot size, regardless of sample resolution.

+ *	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

+ * Driver for AMD7930 sound chips found on Sparcs.
+ * Copyright (C) 2002, 2008 David S. Miller <davem@davemloft.net>
+ *
+ * Based entirely upon drivers/sbus/audio/amd7930.c which is:
+ * 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.
+ * --- End of notes from Thoamas's original driver ---

+ * Driver for DBRI sound chip found on Sparcs.
+ * Copyright (C) 2004, 2005 Martin Habets (mhabets@users.sourceforge.net)
+ *
+ * Converted to ring buffered version by Krzysztof Helt (krzysztof.h1@wp.pl)
+ *
+ * Based entirely upon drivers/sbus/audio/dbri.c which is:
+ * Copyright (C) 1997 Rudolf Koenig (rfkoenig@immd4.informatik.uni-erlangen.de)
+ * Copyright (C) 1998, 1999 Brent Baccala (baccala@freesoft.org)
+ *
+ * This is the low level driver for the DBRI & MMCODEC duo used for ISDN & AUDIO
+ * on Sun SPARCStation 10, 20, LX and Voyager models.
+ *
+ * - DBRI: AT&T T5900FX Dual Basic Rates ISDN Interface. It is a 32 channel
+ *   data time multiplexer with ISDN support (aka T7259)
+ *   Interfaces: SBus,ISDN NT & TE, CHI, 4 bits parallel.
+ *   CHI: (spelled ki) Concentration Highway Interface (AT&T or Intel bus ?).
+ *   Documentation:
+ *   - "STP 4000SBus Dual Basic Rate ISDN (DBRI) Transceiver" from
+ *     Sparc Technology Business (courtesy of Sun Support)
+ *   - Data sheet of the T7903, a newer but very similar ISA bus equivalent
+ *     available from the Lucent (formerly AT&T microelectronics) home
+ *     page.
+ *   - http://www.freesoft.org/Linux/DBRI/
+ * - MMCODEC: Crystal Semiconductor CS4215 16 bit Multimedia Audio Codec
+ *   Interfaces: CHI, Audio In & Out, 2 bits parallel
+ *   Documentation: from the Crystal Semiconductor home page.
+ *
+ * The DBRI is a 32 pipe machine, each pipe can transfer some bits between
+ * memory and a serial device (long pipes, no. 0-15) or between two serial
+ * devices (short pipes, no. 16-31), or simply send a fixed data to a serial
+ * device (short pipes).
+ * A timeslot defines the bit-offset and no. of bits read from a serial device.
+ * The timeslots are linked to 6 circular lists, one for each direction for
+ * each serial device (NT,TE,CHI). A timeslot is associated to 1 or 2 pipes
+ * (the second one is a monitor/tee pipe, valid only for serial input).
+ *
+ * The mmcodec is connected via the CHI bus and needs the data & some
+ * parameters (volume, output selection) time multiplexed in 8 byte
+ * chunks. It also has a control mode, which serves for audio format setting.
+ *
+ * Looking at the CS4215 data sheet it is easy to set up 2 or 4 codecs on
+ * the same CHI bus, so I thought perhaps it is possible to use the on-board
+ * & the speakerbox codec simultaneously, giving 2 (not very independent :-)
+ * audio devices. But the SUN HW group decided against it, at least on my
+ * LX the speakerbox connector has at least 1 pin missing and 1 wrongly
+ * connected.
+ *
+ * I've tried to stick to the following function naming conventions:
+ * snd_*	ALSA stuff
+ * cs4215_*	CS4215 codec specific stuff
+ * dbri_*	DBRI high-level stuff
+ * other	DBRI low-level stuff

+****************************************************************************
+************** DBRI initialization and command synchronization *************
+****************************************************************************
+
+Commands are sent to the DBRI by building a list of them in memory,
+then writing the address of the first list item to DBRI register 8.
+The list is terminated with a WAIT command, which generates a
+CPU interrupt to signal completion.
+
+Since the DBRI can run in parallel with the CPU, several means of
+synchronization present themselves. The method implemented here uses
+the dbri_cmdwait() to wait for execution of batch of sent commands.
+
+A circular command buffer is used here. A new command is being added
+while another can be executed. The scheme works by adding two WAIT commands
+after each sent batch of commands. When the next batch is prepared it is
+added after the WAIT commands then the WAITs are replaced with single JUMP
+command to the new batch. The the DBRI is forced to reread the last WAIT
+command (replaced by the JUMP by then). If the DBRI is still executing
+previous commands the request to reread the WAIT command is ignored.
+
+Every time a routine wants to write commands to the DBRI, it must
+first call dbri_cmdlock() and get pointer to a free space in
+dbri->dma->cmd buffer. After this, the commands can be written to
+the buffer, and dbri_cmdsend() is called with the final pointer value
+to send them to the DBRI.

+ *     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
+ *
+2005-04-14 Karsten Wiese
+	Version 0.8.7.2:
+	Call snd_card_free() instead of snd_card_free_in_thread() to prevent oops with dead keyboard symptom.
+	Tested ok with kernel 2.6.12-rc2.
+
+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 dependent 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, functionalities should migrate to more appropriate 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.
