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

+ * Author: Manuel Jander (mjander@embedded.cl)
+ *
+ *   This driver is the result of the OpenVortex Project from Savannah
+ * (savannah.nongnu.org/projects/openvortex). I would like to thank
+ * the developers of OpenVortex, Jeff Muizelaar and Kester Maddock, from
+ * whom i got plenty of help, and their codebase was invaluable.
+ *   Thanks to the ALSA developers, they helped a lot working out
+ * the ALSA part.
+ *   Thanks also to Sourceforge for maintaining the old binary drivers,
+ * and the forum, where developers could comunicate.
+ *
+ * Now at least i can play Legacy DOOM with MIDI music :-)

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

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

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

+ *  Copyright (c) 2004 James Courtier-Dutton <James@superbug.demon.co.uk>
+ *  Driver CA0106 chips. e.g. Sound Blaster Audigy LS and Live 24bit
+ *  Version: 0.0.22
+ *
+ *  FEATURES currently supported:
+ *    Front, Rear and Center/LFE.
+ *    Surround40 and Surround51.
+ *    Capture from MIC an LINE IN input.
+ *    SPDIF digital playback of PCM stereo and AC3/DTS works.
+ *    (One can use a standard mono mini-jack to one RCA plugs cable.
+ *     or one can use a standard stereo mini-jack to two RCA plugs cable.
+ *     Plug one of the RCA plugs into the Coax input of the external decoder/receiver.)
+ *    ( In theory one could output 3 different AC3 streams at once, to 3 different SPDIF outputs. )
+ *    Notes on how to capture sound:
+ *      The AC97 is used in the PLAYBACK direction.
+ *      The output from the AC97 chip, instead of reaching the speakers, is fed into the Philips 1361T ADC.
+ *      So, to record from the MIC, set the MIC Playback volume to max,
+ *      unmute the MIC and turn up the MASTER Playback volume.
+ *      So, to prevent feedback when capturing, minimise the "Capture feedback into Playback" volume.
+ *   
+ *    The only playback controls that currently do anything are: -
+ *    Analog Front
+ *    Analog Rear
+ *    Analog Center/LFE
+ *    SPDIF Front
+ *    SPDIF Rear
+ *    SPDIF Center/LFE
+ *   
+ *    For capture from Mic in or Line in.
+ *    Digital/Analog ( switch must be in Analog mode for CAPTURE. )
+ * 
+ *    CAPTURE feedback into PLAYBACK
+ * 
+ *  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 controll.
+ *    - On the Hercules Game Theater XP the amplifier are sometimes turned
+ *      off on inadecuate moments which causes distorcions on sound.
+ *
+ *  TODO:
+ *    - Secondary CODEC on some soundcards
+ *    - SPDIF input support for other sample rates then 48khz
+ *    - Posibility to mix the SPDIF output with analog sources.
+ *    - PCM channels for Center and LFE on secondary codec
+ *
+ *  NOTE: with CONFIG_SND_CS46XX_NEW_DSP unset uses old DSP image (which
+ *        is default configuration), no SPDIF, no secondary codec, no
+ *        multi channel PCM.  But known to work.
+ *
+ *  FINALLY: A credit to the developers Tom and Jordan 
+ *           at Cirrus for have helping me out with the DSP, however we
+ *           still don't have sufficient documentation and technical
+ *           references to be able to implement all fancy feutures
+ *           supported by the cs46xx DSP's.

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

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

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

+ *
+ *  Notes from Zach Brown about the driver code
+ *
+ *  Hardware Description
+ *
+ *      A working Maestro setup contains the Maestro chip wired to a 
+ *      codec or 2.  In the Maestro we have the APUs, the ASSP, and the
+ *      Wavecache.  The APUs can be though of as virtual audio routing
+ *      channels.  They can take data from a number of sources and perform
+ *      basic encodings of the data.  The wavecache is a storehouse for
+ *      PCM data.  Typically it deals with PCI and interracts with the
+ *      APUs.  The ASSP is a wacky DSP like device that ESS is loth
+ *      to release docs on.  Thankfully it isn't required on the Maestro
+ *      until you start doing insane things like FM emulation and surround
+ *      encoding.  The codecs are almost always AC-97 compliant codecs, 
+ *      but it appears that early Maestros may have had PT101 (an ESS
+ *      part?) wired to them.  The only real difference in the Maestro
+ *      families is external goop like docking capability, memory for
+ *      the ASSP, and initialization differences.
+ *
+ *  Driver Operation
+ *
+ *      We only drive the APU/Wavecache as typical DACs and drive the
+ *      mixers in the codecs.  There are 64 APUs.  We assign 6 to each
+ *      /dev/dsp? device.  2 channels for output, and 4 channels for
+ *      input.
+ *
+ *      Each APU can do a number of things, but we only really use
+ *      3 basic functions.  For playback we use them to convert PCM
+ *      data fetched over PCI by the wavecahche into analog data that
+ *      is handed to the codec.  One APU for mono, and a pair for stereo.
+ *      When in stereo, the combination of smarts in the APU and Wavecache
+ *      decide which wavecache gets the left or right channel.
+ *
+ *      For record we still use the old overly mono system.  For each in
+ *      coming channel the data comes in from the codec, through a 'input'
+ *      APU, through another rate converter APU, and then into memory via
+ *      the wavecache and PCI.  If its stereo, we mash it back into LRLR in
+ *      software.  The pass between the 2 APUs is supposedly what requires us
+ *      to have a 512 byte buffer sitting around in wavecache/memory.
+ *
+ *      The wavecache makes our life even more fun.  First off, it can
+ *      only address the first 28 bits of PCI address space, making it
+ *      useless on quite a few architectures.  Secondly, its insane.
+ *      It claims to fetch from 4 regions of PCI space, each 4 meg in length.
+ *      But that doesn't really work.  You can only use 1 region.  So all our
+ *      allocations have to be in 4meg of each other.  Booo.  Hiss.
+ *      So we have a module parameter, dsps_order, that is the order of
+ *      the number of dsps to provide.  All their buffer space is allocated
+ *      on open time.  The sonicvibes OSS routines we inherited really want
+ *      power of 2 buffers, so we have all those next to each other, then
+ *      512 byte regions for the recording wavecaches.  This ends up
+ *      wasting quite a bit of memory.  The only fixes I can see would be 
+ *      getting a kernel allocator that could work in zones, or figuring out
+ *      just how to coerce the WP into doing what we want.
+ *
+ *      The indirection of the various registers means we have to spinlock
+ *      nearly all register accesses.  We have the main register indirection
+ *      like the wave cache, maestro registers, etc.  Then we have beasts
+ *      like the APU interface that is indirect registers gotten at through
+ *      the main maestro indirection.  Ouch.  We spinlock around the actual
+ *      ports on a per card basis.  This means spinlock activity at each IO
+ *      operation, but the only IO operation clusters are in non critical 
+ *      paths and it makes the code far easier to follow.  Interrupts are
+ *      blocked while holding the locks because the int handler has to
+ *      get at some of them :(.  The mixer interface doesn't, however.
+ *      We also have an OSS state lock that is thrown around in a few
+ *      places.

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

+/*
+  NOTES:
+  - spdif nonaudio consumer mode does not work (at least with my
+    Sony STR-DB830)
+*/
+
+/*
+ * Changes:
+ *
+ *  2002.09.09  Takashi Iwai <tiwai@suse.de>
+ *      split the code to several files.  each low-level routine
+ *      is stored in the local file and called from registration
+ *      function from card_info struct.
+ *
+ *  2002.11.26  James Stafford <jstafford@ampltd.com>
+ *      Added support for VT1724 (Envy24HT)
+ *      I have left out support for 176.4 and 192 KHz for the moment. 
+ *  I also haven't done anything with the internal S/PDIF transmitter or the MPU-401
+ *
+ *  2003.02.20  Taksahi Iwai <tiwai@suse.de>
+ *      Split vt1724 part to an independent driver.
+ *      The GPIO is accessed through the callback functions now.
+ *
+ * 2004.03.31 Doug McLain <nostar@comcast.net>
+ *    Added support for Event Electronics EZ8 card to hoontech.c.

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

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

+ * 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.
