- * ALI ali5455 and friends ICH driver for Linux
- * LEI HU <Lei_Hu@ali.com.tw>
- *
- * Built from:
- * drivers/sound/i810_audio
- *
- * The ALi 5455 is similar but not quite identical to the Intel ICH
- * series of controllers. Its easier to keep the driver separated from
- * the i810 driver.

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

- * 06.27.2001 Initial version
- * 03.20.2002 Added mutex locks around read/write methods, to prevent

- * removed the counter/pointer fragment aligning at the end
- * of read/write methods [stevel].
- * 03.21.2002 Add support for coherent DMA on the audio read/write DMA
- * channels [stevel].

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

-*
-* Modification History
-* 08/20/00 trw - silence and no stopping DAC until release
-* 08/23/00 trw - added CS_DBG statements, fix interrupt hang issue on DAC stop.
-* 09/18/00 trw - added 16bit only record with conversion
-* 09/24/00 trw - added Enhanced Full duplex (separate simultaneous
-* capture/playback rates)
-* 10/03/00 trw - fixed mmap (fixed GRECORD and the XMMS mmap test plugin
-* libOSSm.so)
-* 10/11/00 trw - modified for 2.4.0-test9 kernel enhancements (NR_MAP removal)
-* 11/03/00 trw - fixed interrupt loss/stutter, added debug.
-* 11/10/00 bkz - added __devinit to cs4281_hw_init()
-* 11/10/00 trw - fixed SMP and capture spinlock hang.
-* 12/04/00 trw - cleaned up CSDEBUG flags and added "defaultorder" moduleparm.
-* 12/05/00 trw - fixed polling (myth2), and added underrun swptr fix.
-* 12/08/00 trw - added PM support.
-* 12/14/00 trw - added wrapper code, builds under 2.4.0, 2.2.17-20, 2.2.17-8
-* (RH/Dell base), 2.2.18, 2.2.12. cleaned up code mods by ident.
-* 12/19/00 trw - added PM support for 2.2 base (apm_callback). other PM cleanup.
-* 12/21/00 trw - added fractional "defaultorder" inputs. if >100 then use
-* defaultorder-100 as power of 2 for the buffer size. example:
-* 106 = 2^(106-100) = 2^6 = 64 bytes for the buffer size.

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

- * Module command line parameters:
- * none so far
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * Revision history
- * 10.11.1998 0.1 Initial release (without any hardware)
- * 22.03.1999 0.2 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 07.04.1999 0.3 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * 15.06.1999 0.4 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.5 Add pci_set_master
- * 12.08.1999 0.6 Fix MIDI UART crashing the driver
- * Changed mixer semantics from OSS documented
- * behaviour to OSS "code behaviour".
- * Recording might actually work now.
- * The real DDMA controller address register is at PCI config
- * 0x60, while the register at 0x18 is used as a placeholder
- * register for BIOS address allocation. This register
- * is supposed to be copied into 0x60, according
- * to the Solo1 datasheet. When I do that, I can access
- * the DDMA registers except the mask bit, which
- * is stuck at 1. When I copy the contents of 0x18 +0x10
- * to the DDMA base register, everything seems to work.
- * The fun part is that the Windows Solo1 driver doesn't
- * seem to do these tricks.
- * Bugs remaining: plops and clicks when starting/stopping playback
- * 31.08.1999 0.7 add spin_lock_init
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.8 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 07.10.1999 0.9 Fix initialization; complain if sequencer writes time out
- * Revised resource grabbing for the FM synthesizer
- * 28.10.1999 0.10 More waitqueue races fixed
- * 09.12.1999 0.11 Work around stupid Alpha port issue (virt_to_bus(kmalloc(GFP_DMA)) > 16M)
- * Disabling recording on Alpha
- * 12.01.2000 0.12 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * Integrated (aka redid 8-)) APM support patch by Zach Brown
- * 07.02.2000 0.13 Use pci_alloc_consistent and pci_register_driver
- * 19.02.2000 0.14 Use pci_dma_supported to determine if recording should be disabled
- * 13.03.2000 0.15 Reintroduce initialization of a couple of PCI config space registers
- * 21.11.2000 0.16 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.17 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
- * 31.01.2001 0.18 Register/Unregister gameport, original patch from
- * Nathaniel Daw <daw@cs.cmu.edu>
- * Fix SETTRIGGER non OSS API conformity
- * 10.03.2001 provide abs function, prevent picking up a bogus kernel macro
- * for abs. Bug report by Andrew Morton <andrewm@uow.edu.au>
- * 15.05.2001 pci_enable_device moved, return values in probe cleaned
- * up. Marcus Meissner <mm@caldera.de>
- * 22.05.2001 0.19 more cleanups, changed PM to PCI 2.4 style, got rid
- * of global list of devices, using pci device data.
- * Marcus Meissner <mm@caldera.de>
- * 03.01.2003 0.20 open_mode fixes from Georg Acher <acher@in.tum.de>

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

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

- * Based heavily on SonicVibes.c:
- * Copyright (C) 1998-1999 Thomas Sailer (sailer@ife.ee.ethz.ch)
- *
- * Heavily modified by Zach Brown <zab@zabbo.net> based on lunch

- * Supported devices:
- * /dev/dsp0-3 standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- *
- * Hardware Description
- *
- * A working Maestro setup contains the Maestro chip wired to a
- * codec or 2. In the Maestro we have the APUs, the ASSP, and the
- * Wavecache. The APUs can be though of as virtual audio routing
- * channels. They can take data from a number of sources and perform
- * basic encodings of the data. The wavecache is a storehouse for
- * PCM data. Typically it deals with PCI and interracts with the
- * APUs. The ASSP is a wacky DSP like device that ESS is loth
- * to release docs on. Thankfully it isn't required on the Maestro
- * until you start doing insane things like FM emulation and surround
- * encoding. The codecs are almost always AC-97 compliant codecs,
- * but it appears that early Maestros may have had PT101 (an ESS
- * part?) wired to them. The only real difference in the Maestro
- * families is external goop like docking capability, memory for
- * the ASSP, and initialization differences.
- *
- * Driver Operation
- *
- * We only drive the APU/Wavecache as typical DACs and drive the
- * mixers in the codecs. There are 64 APUs. We assign 6 to each
- * /dev/dsp? device. 2 channels for output, and 4 channels for
- * input.
- *
- * Each APU can do a number of things, but we only really use
- * 3 basic functions. For playback we use them to convert PCM
- * data fetched over PCI by the wavecahche into analog data that
- * is handed to the codec. One APU for mono, and a pair for stereo.
- * When in stereo, the combination of smarts in the APU and Wavecache
- * decide which wavecache gets the left or right channel.
- *
- * For record we still use the old overly mono system. For each in
- * coming channel the data comes in from the codec, through a 'input'
- * APU, through another rate converter APU, and then into memory via
- * the wavecache and PCI. If its stereo, we mash it back into LRLR in
- * software. The pass between the 2 APUs is supposedly what requires us
- * to have a 512 byte buffer sitting around in wavecache/memory.
- *
- * The wavecache makes our life even more fun. First off, it can
- * only address the first 28 bits of PCI address space, making it
- * useless on quite a few architectures. Secondly, its insane.
- * It claims to fetch from 4 regions of PCI space, each 4 meg in length.
- * But that doesn't really work. You can only use 1 region. So all our
- * allocations have to be in 4meg of each other. Booo. Hiss.
- * So we have a module parameter, dsps_order, that is the order of
- * the number of dsps to provide. All their buffer space is allocated
- * on open time. The sonicvibes OSS routines we inherited really want
- * power of 2 buffers, so we have all those next to each other, then
- * 512 byte regions for the recording wavecaches. This ends up
- * wasting quite a bit of memory. The only fixes I can see would be
- * getting a kernel allocator that could work in zones, or figuring out
- * just how to coerce the WP into doing what we want.
- *
- * The indirection of the various registers means we have to spinlock
- * nearly all register accesses. We have the main register indirection
- * like the wave cache, maestro registers, etc. Then we have beasts
- * like the APU interface that is indirect registers gotten at through
- * the main maestro indirection. Ouch. We spinlock around the actual
- * ports on a per card basis. This means spinlock activity at each IO
- * operation, but the only IO operation clusters are in non critical
- * paths and it makes the code far easier to follow. Interrupts are
- * blocked while holding the locks because the int handler has to
- * get at some of them :(. The mixer interface doesn't, however.
- * We also have an OSS state lock that is thrown around in a few
- * places.
- *
- * This driver has brute force APM suspend support. We catch suspend
- * notifications and stop all work being done on the chip. Any people
- * that try between this shutdown and the real suspend operation will
- * be put to sleep. When we resume we restore our software state on
- * the chip and wake up the people that were using it. The code thats
- * being used now is quite dirty and assumes we're on a uni-processor
- * machine. Much of it will need to be cleaned up for SMP ACPI or
- * similar.
- *
- * We also pay attention to PCI power management now. The driver
- * will power down units of the chip that it knows aren't needed.
- * The WaveProcessor and company are only powered on when people
- * have /dev/dsp*s open. On removal the driver will
- * power down the maestro entirely. There could still be
- * trouble with BIOSen that magically change power states
- * themselves, but we'll see.
- *
- * History
- * v0.15 - May 21 2001 - Marcus Meissner <mm@caldera.de>
- * Ported to Linux 2.4 PCI API. Some clean ups, global devs list
- * removed (now using pci device driver data).
- * PM needs to be polished still. Bumped version.
- * (still kind of v0.14) May 13 2001 - Ben Pfaff <pfaffben@msu.edu>
- * Add support for 978 docking and basic hardware volume control
- * (still kind of v0.14) Nov 23 - Alan Cox <alan@redhat.com>
- * Add clocking= for people with seriously warped hardware
- * (still v0.14) Nov 10 2000 - Bartlomiej Zolnierkiewicz <bkz@linux-ide.org>
- * add __init to maestro_ac97_init() and maestro_install()
- * (still based on v0.14) Mar 29 2000 - Zach Brown <zab@redhat.com>
- * move to 2.3 power management interface, which
- * required hacking some suspend/resume/check paths
- * make static compilation work
- * v0.14 - Jan 28 2000 - Zach Brown <zab@redhat.com>
- * add PCI power management through ACPI regs.

- * v0.05 - Sep 17 1999 - Zach Brown <zab@redhat.com>
- * merged and fixed up Eric's initial recording code
- * munged format handling to catch misuse, needs rewrite.
- * revert ring bus init, fixup shared int, add pci busmaster setting
- * fix mixer oss interface, fix mic mute and recmask
- * mask off unsupported mixers, reset with all 1s, modularize defaults
- * make sure bob is running while we need it
- * got rid of device limit, initial minimal apm hooks
- * pull out dead code/includes, only allow multimedia/audio maestros
- * v0.04 - Sep 01 1999 - Zach Brown <zab@redhat.com>
- * copied memory leak fix from sonicvibes driver
- * different ac97 reset, play with 2.0 ac97, simplify ring bus setup
- * bob freq code, region sanity, jitter sync fix; all from Eric
- *
- * TODO
- * fix bob frequency
- * endianness
- * do smart things with ac97 2.0 bits.
- * dual codecs
- * leave 54->61 open
- *
- * it also would be fun to have a mode that would not use pci dma at all
- * but would copy into the wavecache on board memory and use that
- * on architectures that don't like the maestro's pci dma ickiness.

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

- - test more than one card --- done
- - check for pci IOREGION (see es1370) in rme96xx_probe ??
- - error detection
- - mmap interface
- - mixer mmap interface
- - mixer ioctl
- - get rid of noise upon first open (why ??)
- - allow multiple open (at least for read)
- - allow multiple open for non overlapping regions
- - recheck the multiple devices part (offsets of different devices, etc)
- - do decent draining in _release --- done
- - SMP support
- - what about using fragstotal>2 for small fragsize? (HP20020118)
- - add support for AFMT_S32_LE

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

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

- * Although the relevant code here is all new, the handling of

- *
- * Absolutely NO thanks to Turtle Beach/Voyetra and Yamaha for their

- 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

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

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