*
|
||
* 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 M<>ller <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
|
||
* 03.01.2003 0.32 open_mode fixes from Georg Acher <acher@in.tum.de>
