-/proc/sound, /dev/sndstat
--------------------------
-
-/proc/sound and /dev/sndstat is not supported by the
-driver. To find out whether the driver succeeded loading,
-check the kernel log (dmesg).
-
-
-ALaw/uLaw sample formats
-------------------------
-
-This driver does not support the ALaw/uLaw sample formats.
-ALaw is the default mode when opening a sound device
-using OSS/Free. The reason for the lack of support is
-that the hardware does not support these formats, and adding
-conversion routines to the kernel would lead to very ugly
-code in the presence of the mmap interface to the driver.
-And since xquake uses mmap, mmap is considered important :-)
-and no sane application uses ALaw/uLaw these days anyway.
-In short, playing a Sun .au file as follows:
-
-cat my_file.au > /dev/dsp
-
-does not work. Instead, you may use the play script from
-Chris Bagwell's sox-12.14 package (available from the URL
-below) to play many different audio file formats.
-The script automatically determines the audio format
-and does do audio conversions if necessary.
-http://home.sprynet.com/sprynet/cbagwell/projects.html
-
-
-Blocking vs. nonblocking IO
----------------------------
-
-Unlike OSS/Free this driver honours the O_NONBLOCK file flag
-not only during open, but also during read and write.
-This is an effort to make the sound driver interface more
-regular. Timidity has problems with this; a patch
-is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html.
-(Timidity patched will also run on OSS/Free).
-
-
-MIDI UART
----------
-
-The driver supports a simple MIDI UART interface, with
-no ioctl's supported.
-
-
-MIDI synthesizer
-----------------
-
-This soundcard does not have any hardware MIDI synthesizer;
-MIDI synthesis has to be done in software. To allow this
-the driver/soundcard supports two PCM (/dev/dsp) interfaces.
-
-There is a freely available software package that allows
-MIDI file playback on this soundcard called Timidity.
-See http://www.cgs.fi/~tt/timidity/.

- *  linux/sound/oss/dmasound/dmasound_awacs.c

- *  with some limited support for DACA & Tumbler
- *
- *  See linux/sound/oss/dmasound/dmasound_core.c for copyright and
- *  history prior to 2001/01/26.
- *
- *	26/01/2001 ed 0.1 Iain Sandoe
- *		- added version info.
- *		- moved dbdma command buffer allocation to PMacXXXSqSetup()
- *		- fixed up beep dbdma cmd buffers
- *
- *	08/02/2001 [0.2]
- *		- make SNDCTL_DSP_GETFMTS return the correct info for the h/w
- *		- move soft format translations to a separate file
- *		- [0.3] make SNDCTL_DSP_GETCAPS return correct info.
- *		- [0.4] more informative machine name strings.
- *		- [0.5]
- *		- record changes.
- *		- made the default_hard/soft entries.
- *	04/04/2001 [0.6]
- *		- minor correction to bit assignments in awacs_defs.h
- *		- incorporate mixer changes from 2.2.x back-port.
- *		- take out passthru as a rec input (it isn't).
- *              - make Input Gain slider work the 'right way up'.
- *              - try to make the mixer sliders more logical - so now the
- *                input selectors are just two-state (>50% == ON) and the
- *                Input Gain slider handles the rest of the gain issues.
- *              - try to pick slider representations that most closely match
- *                the actual use - e.g. IGain for input gain... 
- *              - first stab at over/under-run detection.
- *		- minor cosmetic changes to IRQ identification.
- *		- fix bug where rates > max would be reported as supported.
- *              - first stab at over/under-run detection.
- *              - make use of i2c for mixer settings conditional on perch
- *                rather than cuda (some machines without perch have cuda).
- *              - fix bug where TX stops when dbdma status comes up "DEAD"
- *		  so far only reported on PowerComputing clones ... but.
- *		- put in AWACS/Screamer register write timeouts.
- *		- part way to partitioning the init() stuff
- *		- first pass at 'tumbler' stuff (not support - just an attempt
- *		  to allow the driver to load on new G4s).
- *      01/02/2002 [0.7] - BenH
- *	        - all sort of minor bits went in since the latest update, I
- *	          bumped the version number for that reason
- *
- *      07/26/2002 [0.8] - BenH
- *	        - More minor bits since last changelog (I should be more careful
- *	          with those)
- *	        - Support for snapper & better tumbler integration by Toby Sargeant
- *	        - Headphone detect for scremer by Julien Blache
- *	        - More tumbler fixed by Andreas Schwab
- *	11/29/2003 [0.8.1] - Renzo Davoli (King Enzo)
- *		- Support for Snapper line in
- *		- snapper input resampling (for rates < 44100)
- *		- software line gain control

- * Special thanks to Ensoniq
- *
- *  Supported devices:
- *  /dev/dsp    standard /dev/dsp device, (mostly) OSS compatible
- *  /dev/mixer  standard /dev/mixer device, (mostly) OSS compatible
- *  /dev/dsp1   additional DAC, like /dev/dsp, but outputs to mixer "SYNTH" setting
- *  /dev/midi   simple MIDI UART interface, no ioctl
- *
- *  NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
- *  to be done in software. That is what /dev/dac is for. By now (Q2 1998)
- *  there are several MIDI to PCM (WAV) packages, one of them is timidity.
- *
- *  Revision history
- *    04.06.1998   0.1   Initial release
- *                       Mixer stuff should be overhauled; especially optional AC97 mixer bits
- *                       should be detected. This results in strange behaviour of some mixer
- *                       settings, like master volume and mic.
- *    08.06.1998   0.2   First release using Alan Cox' soundcore instead of miscdevice
- *    03.08.1998   0.3   Do not include modversions.h
- *                       Now mixer behaviour can basically be selected between
- *                       "OSS documented" and "OSS actual" behaviour
- *    31.08.1998   0.4   Fix realplayer problems - dac.count issues
- *    27.10.1998   0.5   Fix joystick support
- *                       -- Oliver Neukum (c188@org.chemie.uni-muenchen.de)
- *    10.12.1998   0.6   Fix drain_dac trying to wait on not yet initialized DMA
- *    23.12.1998   0.7   Fix a few f_file & FMODE_ bugs
- *                       Don't wake up app until there are fragsize bytes to read/write
- *    06.01.1999   0.8   remove the silly SA_INTERRUPT flag.
- *                       hopefully killed the egcs section type conflict
- *    12.03.1999   0.9   cinfo.blocks should be reset after GETxPTR ioctl.
- *                       reported by Johan Maes <joma@telindus.be>
- *    22.03.1999   0.10  return EAGAIN instead of EBUSY when O_NONBLOCK
- *                       read/write cannot be executed
- *    07.04.1999   0.11  implemented the following ioctl's: SOUND_PCM_READ_RATE, 
- *                       SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS; 
- *                       Alpha fixes reported by Peter Jones <pjones@redhat.com>
- *                       Another Alpha fix (wait_src_ready in init routine)
- *                       reported by "Ivan N. Kokshaysky" <ink@jurassic.park.msu.ru>
- *                       Note: joystick address handling might still be wrong on archs
- *                       other than i386
- *    15.06.1999   0.12  Fix bad allocation bug.
- *                       Thanks to Deti Fliegl <fliegl@in.tum.de>
- *    28.06.1999   0.13  Add pci_set_master
- *    03.08.1999   0.14  adapt to Linus' new __setup/__initcall
- *                       added kernel command line option "es1371=joystickaddr"
- *                       removed CONFIG_SOUND_ES1371_JOYPORT_BOOT kludge
- *    10.08.1999   0.15  (Re)added S/PDIF module option for cards revision >= 4.
- *                       Initial version by Dave Platt <dplatt@snulbug.mtview.ca.us>.
- *                       module_init/__setup fixes
- *    08.16.1999   0.16  Joe Cotellese <joec@ensoniq.com>
- *                       Added detection for ES1371 revision ID so that we can
- *                       detect the ES1373 and later parts.
- *                       added AC97 #defines for readability
- *                       added a /proc file system for dumping hardware state
- *                       updated SRC and CODEC w/r functions to accommodate bugs
- *                       in some versions of the ES137x chips.
- *    31.08.1999   0.17  add spin_lock_init
- *                       replaced current->state = x with set_current_state(x)
- *    03.09.1999   0.18  change read semantics for MIDI to match
