---------------------------
-What: drivers depending on OBSOLETE_OSS
-When: options in 2.6.22, code in 2.6.24
-Why: OSS drivers with ALSA replacements
-Who: Adrian Bunk <bunk@stusta.de>
-
----------------------------
-
What: ACPI procfs interface
When: July 2008
Why: ACPI sysfs conversion should be finished by January 2008.
+++ /dev/null
-/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
- *
- * PowerMac `AWACS' and `Burgundy' DMA Sound Driver
- * 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
- */

-/* GENERAL FIXME/TODO: check that the assumptions about what is written to
- mac-io is valid for DACA & Tumbler.
-
- This driver is in bad need of a rewrite. The dbdma code has to be split,
- some proper device-tree parsing code has to be written, etc...

- * 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
- * OSS more closely; remove possible wakeup race
- * 21.10.1999 0.19 Round sampling rates, requested by
- * Kasamatsu Kenichi <t29w0267@ip.media.kyoto-u.ac.jp>
- * 27.10.1999 0.20 Added SigmaTel 3D enhancement string
- * Codec ID printing changes
- * 28.10.1999 0.21 More waitqueue races fixed
- * Joe Cotellese <joec@ensoniq.com>
- * Changed PCI detection routine so we can more easily
- * detect ES137x chip and derivatives.
- * 05.01.2000 0.22 Should now work with rev7 boards; patch by
- * Eric Lemar, elemar@cs.washington.edu
- * 08.01.2000 0.23 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * 07.02.2000 0.24 Use pci_alloc_consistent and pci_register_driver
- * 07.02.2000 0.25 Use ac97_codec
- * 01.03.2000 0.26 SPDIF patch by Mikael Bouillot <mikael.bouillot@bigfoot.com>
- * Use pci_module_init
- * 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>
- * 05.01.2001 0.29 Hopefully updates will not be required anymore when Creative bumps
- * the CT5880 revision.
- * suggested by Stephan Müller <smueller@chronox.de>
- * 31.01.2001 0.30 Register/Unregister gameport
- * Fix SETTRIGGER non OSS API conformity
- * 14.07.2001 0.31 Add list of laptops needing amplifier control
