| 22 | * Special thanks to Ensoniq |
| 23 | * |
| 24 | * Supported devices: |
| 25 | * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible |
| 26 | * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible |
| 27 | * /dev/dsp1 additional DAC, like /dev/dsp, but outputs to mixer "SYNTH" setting |
| 28 | * /dev/midi simple MIDI UART interface, no ioctl |
| 29 | * |
| 30 | * NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed |
| 31 | * to be done in software. That is what /dev/dac is for. By now (Q2 1998) |
| 32 | * there are several MIDI to PCM (WAV) packages, one of them is timidity. |
| 33 | * |
| 34 | * Revision history |
| 35 | * 04.06.1998 0.1 Initial release |
| 36 | * Mixer stuff should be overhauled; especially optional AC97 mixer bits |
| 37 | * should be detected. This results in strange behaviour of some mixer |
| 38 | * settings, like master volume and mic. |
| 39 | * 08.06.1998 0.2 First release using Alan Cox' soundcore instead of miscdevice |
| 40 | * 03.08.1998 0.3 Do not include modversions.h |
| 41 | * Now mixer behaviour can basically be selected between |
| 42 | * "OSS documented" and "OSS actual" behaviour |
| 43 | * 31.08.1998 0.4 Fix realplayer problems - dac.count issues |
| 44 | * 27.10.1998 0.5 Fix joystick support |
| 45 | * -- Oliver Neukum (c188@org.chemie.uni-muenchen.de) |
| 46 | * 10.12.1998 0.6 Fix drain_dac trying to wait on not yet initialized DMA |
| 47 | * 23.12.1998 0.7 Fix a few f_file & FMODE_ bugs |
| 48 | * Don't wake up app until there are fragsize bytes to read/write |
| 49 | * 06.01.1999 0.8 remove the silly SA_INTERRUPT flag. |
| 50 | * hopefully killed the egcs section type conflict |
| 51 | * 12.03.1999 0.9 cinfo.blocks should be reset after GETxPTR ioctl. |
| 52 | * reported by Johan Maes <joma@telindus.be> |
| 53 | * 22.03.1999 0.10 return EAGAIN instead of EBUSY when O_NONBLOCK |
| 54 | * read/write cannot be executed |
| 55 | * 07.04.1999 0.11 implemented the following ioctl's: SOUND_PCM_READ_RATE, |
| 56 | * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS; |
| 57 | * Alpha fixes reported by Peter Jones <pjones@redhat.com> |
| 58 | * Another Alpha fix (wait_src_ready in init routine) |
| 59 | * reported by "Ivan N. Kokshaysky" <ink@jurassic.park.msu.ru> |
| 60 | * Note: joystick address handling might still be wrong on archs |
| 61 | * other than i386 |
| 62 | * 15.06.1999 0.12 Fix bad allocation bug. |
| 63 | * Thanks to Deti Fliegl <fliegl@in.tum.de> |
| 64 | * 28.06.1999 0.13 Add pci_set_master |
| 65 | * 03.08.1999 0.14 adapt to Linus' new __setup/__initcall |
| 66 | * added kernel command line option "es1371=joystickaddr" |
| 67 | * removed CONFIG_SOUND_ES1371_JOYPORT_BOOT kludge |
| 68 | * 10.08.1999 0.15 (Re)added S/PDIF module option for cards revision >= 4. |
| 69 | * Initial version by Dave Platt <dplatt@snulbug.mtview.ca.us>. |
| 70 | * module_init/__setup fixes |
| 71 | * 08.16.1999 0.16 Joe Cotellese <joec@ensoniq.com> |
| 72 | * Added detection for ES1371 revision ID so that we can |
| 73 | * detect the ES1373 and later parts. |
| 74 | * added AC97 #defines for readability |
| 75 | * added a /proc file system for dumping hardware state |
| 76 | * updated SRC and CODEC w/r functions to accommodate bugs |
| 77 | * in some versions of the ES137x chips. |
| 78 | * 31.08.1999 0.17 add spin_lock_init |
| 79 | * replaced current->state = x with set_current_state(x) |
| 80 | * 03.09.1999 0.18 change read semantics for MIDI to match |
| 81 | * OSS more closely; remove possible wakeup race |
| 82 | * 21.10.1999 0.19 Round sampling rates, requested by |
| 83 | * Kasamatsu Kenichi <t29w0267@ip.media.kyoto-u.ac.jp> |
| 84 | * 27.10.1999 0.20 Added SigmaTel 3D enhancement string |
| 85 | * Codec ID printing changes |
| 86 | * 28.10.1999 0.21 More waitqueue races fixed |
| 87 | * Joe Cotellese <joec@ensoniq.com> |
| 88 | * Changed PCI detection routine so we can more easily |
| 89 | * detect ES137x chip and derivatives. |
| 90 | * 05.01.2000 0.22 Should now work with rev7 boards; patch by |
| 91 | * Eric Lemar, elemar@cs.washington.edu |
| 92 | * 08.01.2000 0.23 Prevent some ioctl's from returning bad count values on underrun/overrun; |
| 93 | * Tim Janik's BSE (Bedevilled Sound Engine) found this |
| 94 | * 07.02.2000 0.24 Use pci_alloc_consistent and pci_register_driver |
| 95 | * 07.02.2000 0.25 Use ac97_codec |
| 96 | * 01.03.2000 0.26 SPDIF patch by Mikael Bouillot <mikael.bouillot@bigfoot.com> |
| 97 | * Use pci_module_init |
| 98 | * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask |
| 99 | * 12.12.2000 0.28 More dma buffer initializations, patch from |
| 100 | * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com> |
| 101 | * 05.01.2001 0.29 Hopefully updates will not be required anymore when Creative bumps |
| 102 | * the CT5880 revision. |
