- *	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

- * Notes:

- *     so refer to the credits in es1371.c for those. The rest of the
- *     code (probe, open, read, write, the ISR, etc.) is new.
- *
- *  Revision history
- *    06.27.2001  Initial version
- *    03.20.2002  Added mutex locks around read/write methods, to prevent
- *                simultaneous access on SMP or preemptible kernels. Also
- *                removed the counter/pointer fragment aligning at the end
- *                of read/write methods [stevel].
- *    03.21.2002  Add support for coherent DMA on the audio read/write DMA
- *                channels [stevel].

- *  /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>

-* Module command line parameters:
-*   none
-*
-*  Supported devices:
-*  /dev/dsp    standard /dev/dsp device, (mostly) OSS compatible
-*  /dev/mixer  standard /dev/mixer device, (mostly) OSS compatible
-*  /dev/midi   simple MIDI UART interface, no ioctl
-*
-* Modification History
-* 08/20/00 trw - silence and no stopping DAC until release
-* 08/23/00 trw - added CS_DBG statements, fix interrupt hang issue on DAC stop.
-* 09/18/00 trw - added 16bit only record with conversion 
-* 09/24/00 trw - added Enhanced Full duplex (separate simultaneous 
-*                capture/playback rates)
-* 10/03/00 trw - fixed mmap (fixed GRECORD and the XMMS mmap test plugin  
-*                libOSSm.so)
-* 10/11/00 trw - modified for 2.4.0-test9 kernel enhancements (NR_MAP removal)
-* 11/03/00 trw - fixed interrupt loss/stutter, added debug.
-* 11/10/00 bkz - added __devinit to cs4281_hw_init()
-* 11/10/00 trw - fixed SMP and capture spinlock hang.
-* 12/04/00 trw - cleaned up CSDEBUG flags and added "defaultorder" moduleparm.
-* 12/05/00 trw - fixed polling (myth2), and added underrun swptr fix.
-* 12/08/00 trw - added PM support. 
-* 12/14/00 trw - added wrapper code, builds under 2.4.0, 2.2.17-20, 2.2.17-8 
-*		 (RH/Dell base), 2.2.18, 2.2.12.  cleaned up code mods by ident.
-* 12/19/00 trw - added PM support for 2.2 base (apm_callback). other PM cleanup.
-* 12/21/00 trw - added fractional "defaultorder" inputs. if >100 then use 
-*		 defaultorder-100 as power of 2 for the buffer size. example:
-*		 106 = 2^(106-100) = 2^6 = 64 bytes for the buffer size.

- *
- * 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

- *                       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

- *    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.

- *                       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

- *                       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.

- * and vary PCLKDIV to obtain zero beat.
- *  5512sps:  254
- * 44100sps:   30
- * seems to be fs = 1411200/(PCLKDIV+2)
- *
- * should find out when curr_sample_ct is cleared and
- * where exactly the CCB fetches data
- *
- * The card uses a 22.5792 MHz crystal.
- * The LINEIN jack may be converted to an AOUT jack by
- * setting pin 47 (XCTL0) of the ES1370 to high.

- * 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.

- *      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

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

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

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

- *
- * 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.

-		       Modifications - Heiko Purnhagen <purnhage@tnt.uni-hannover.de>
-		       HP20020108 fixed handling of "large" read()
-		       HP20020116 towards REV 1.5 support, based on ALSA's card-rme9652.c
-		       HP20020118 made mixer ioctl and handling of devices>1 more safe
-		       HP20020201 fixed handling of "large" read() properly
-		       added REV 1.5 S/P-DIF receiver support
-		       SNDCTL_DSP_SPEED now returns the actual speed
-   *  10 Aug 2002: added synchronize_irq() again
-
-TODO:
-   - test more than one card --- done
-   - check for pci IOREGION (see es1370) in rme96xx_probe ??
-   - error detection
-   - mmap interface
-   - mixer mmap interface
-   - mixer ioctl
-   - get rid of noise upon first open (why ??)
-   - allow multiple open (at least for read)
-   - allow multiple open for non overlapping regions
-   - recheck the multiple devices part (offsets of different devices, etc)
-   - do decent draining in _release --- done
-   - SMP support
-   - what about using fragstotal>2 for small fragsize? (HP20020118)
-   - add support for AFMT_S32_LE

- * Module command line parameters:

- *
- *
- *  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>

-/*  -*- linux-c -*-
- *
- * 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
- *

-Sometimes, we need to munge numeric values that are represented on

-that is represented on the x86 side as an array of bytes. The most

-		   this driver, and so a complete reset (back to General MIDI,
-		   or theoretically some other configuration) is the
-		   responsibility of the user level library. 
-

- * 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.
