sound: Retire OSS
Since no complaints have been raised after disabling the build of OSS
(Open Sound System) by the commit 31cbee6a5611 ("sound: Disable the
build of OSS drivers"), let's finally drop the whole code and
documentation.
Some glue codes are still left intact since sound/oss/dmasound stuff
remains -- which is an independent implementation solely for m68k, and
it's not covered by ALSA yet.
Also, a couple of API header files (linux/sound.h and
linux/soundcard.h) are kept remaining as well, since the OSS API
itself is still supported by ALSA OSS emulation, and applications can
refer to these.
Where we're at it, some help texts in the top-level Kconfig are
adjusted, too (who still needs to specify I/O port in kbuild
nowadays?).

Also mixer volumes may be seriously wrong on some systems. - You can safely use this driver version with C930 if it looks to work. - However please don't complain if you have problems with it. C930 support - should be fixed in future releases. -- Got initialization of GUS PnP to work. With this version GUS PnP should - work in GUS compatible mode after initialization using isapnptools. -- Fixed a bug in handling of full duplex cards in write only mode. This has - been causing "audio device opening" errors with RealAudio player. - -Since 3.5.4.beta5 -- Changes to OPTi 82C930 driver. -- Major changes to the Soundscape driver. The driver requires now just one - DMA channel. The extra audio/dsp device (the "Not functional" one) used - for code download in the earlier versions has been eliminated.

Many thanks - to James Hightower. - -Since 3.5-beta1 -- Bug fixes. -- Full duplex audio with MAD16+CS4231 may work now. The driver configures - SB DMA of MAD16 so that it doesn't conflict with codec's DMA channels. - The side effect is that all 8 bit DMA channels (0,1,3) are populated in - duplex mode. - -Since 3.5-alpha9 -- Bug fixes (mostly in Jazz16 and ESS1688/688 supports). -- Temporarily disabled recording with ESS1688/688 since it causes crash. -- Changed audio buffer partitioning algorithm so that it selects - smaller fragment size than earlier. This improves real time capabilities - of the driver and makes recording to disk to work better. Unfortunately - this change breaks some programs which assume that fragments cannot be - shorter than 4096 bytes. - -Since 3.5-alpha8 -- Bug fixes - -Since 3.5-alpha7 -- Linux kernel compatible configuration (_EXPERIMENTAL_). Enable - using command "cd /linux/drivers/sound;make script" and then - just run kernel's make config normally. -- Minor fixes to the SB support. Hopefully the driver works with - all SB models now. -- Added support for ESS ES1688 "AudioDrive" based cards. - -Since 3.5-alpha6 -- SB Pro and SB16 supports are no longer separately selectable options. - Enabling SB enables them too. -- Changed all #ifndef EXCLUDE_xx stuff to #ifdef CONFIG_xx. Modified -configure to handle this. -- Removed initialization messages from the -modularized version. They can be enabled by using init_trace=1 in -the insmod command line (insmod sound init_trace=1). -- More AIX stuff. -- Added support for synchronizing dsp/audio devices with /dev/sequencer. -- mmap() support for dsp/audio devices. - -Since 3.5-alpha5 -- AIX port. -- Changed some xxx_PATCH macros in soundcard.h to work with - big endian machines. - -Since 3.5-alpha4 -- Removed the 'setfx' stuff from the version distributed with kernel - sources. Running 'setfx' is required again. - -Since 3.5-alpha3 -- Moved stuff from the 'setfx' program to the AudioTrix Pro driver. - -Since 3.5-alpha2 -- Modifications to makefile and configure.c. Unnecessary sources - are no longer compiled. Newly created local.h is also copied to - /etc/soundconf. "make oldconfig" reads /etc/soundconf and produces - new local.h which is compatible with current version of the driver. -- Some fixes to the SB16 support. -- Fixed random protection fault in gus_wave.c - -Since 3.5-alpha1 -- Modified to work with Linux-1.3.33 and later -- Some minor changes - -Since 3.0.2 -- Support for CS4232 based PnP cards (AcerMagic S23 etc). -- Full duplex support for some CS4231, CS4232 and AD1845 based cards -(GUS MAX, AudioTrix Pro, AcerMagic S23 and many MAD16/Mozart cards -having a codec mentioned above). -- Almost fully rewritten loadable modules support. -- Fixed some bugs. -- Huge amount of testing (more testing is still required). -- mmap() support (works with some cards). Requires much more testing. -- Sample/patch/program loading for TB Maui/Tropez. No initialization -since TB doesn't allow me to release that code. -- Using CS4231 compatible codecs as timer for /dev/music. - -Since 3.0.1 -- Added allocation of I/O ports, DMA channels and interrupts -to the initialization code. This may break modules support since -the driver may not free some resources on unload. Should be fixed soon. - -Since 3.0 -- Some important bug fixes. -- select() for /dev/dsp and /dev/audio (Linux only). -(To use select() with read, you have to call read() to start -the recording. Calling write() kills recording immediately so -use select() carefully when you are writing a half duplex app. -Full duplex mode is not implemented yet.) Select works also with -/dev/sequencer and /dev/music. Maybe with /dev/midi## too. - -Since 3.0-beta2 -- Minor fixes. -- Added Readme.cards - -Since 3.0-beta1 -- Minor fixes to the modules support. -- Eliminated call to sb_free_irq() in ad1848.c -- Rewritten MAD16&Mozart support (not tested with MAD16 Pro). -- Fix to DMA initialization of PSS cards. -- Some fixes to ad1848/cs42xx mixer support (GUS MAX, MSS, etc.) -- Fixed some bugs in the PSS driver which caused I/O errors with - the MSS mode (/dev/dsp). - -Since 3.0-950506 -- Recording with GUS MAX fixed. It works when the driver is configured - to use two DMA channels with GUS MAX (16 bit ones recommended). - -Since 3.0-94xxxx -- Too many changes - -Since 3.0-940818 -- Fixes for Linux 1.1.4x. -- Disables Disney Sound System with SG NX Pro 16 (less noise). - -Since 2.90-2 -- Fixes to soundcard.h -- Non blocking mode to /dev/sequencer -- Experimental detection code for Ensoniq Soundscape. - -Since 2.90 -- Minor and major bug fixes - -Since pre-3.0-940712 -- GUS MAX support -- Partially working MSS/WSS support (could work with some cards). -- Hardware u-Law and A-Law support with AD1848/CS4248 and CS4231 codecs - (GUS MAX, GUS16, WSS etc). Hardware ADPCM is possible with GUS16 and - GUS MAX, but it doesn't work yet. -Since pre-3.0-940426 -- AD1848/CS4248/CS4231 codec support (MSS, GUS MAX, Aztec, Orchid etc). -This codec chip is used in various sound cards. This version is developed -for the 16 bit daughtercard of GUS. It should work with other cards also -if the following requirements are met: - - The I/O, IRQ and DMA settings are jumper selectable or - the card is initialized by booting DOS before booting Linux (etc.). - - You add the IO, IRQ and DMA settings manually to the local.h. - (Just define GUS16_BASE, GUS16_IRQ and GUS16_DMA). Note that - the base address bust be the base address of the codec chip not the - card itself. For the GUS16 these are the same but most MSS compatible - cards have the codec located at card_base+4. -- Some minor changes - -Since 2.5 (******* MAJOR REWRITE ***********) - -This version is based on v2.3. I have tried to maintain two versions -together so that this one should have the same features than v2.5. -Something may still be missing. If you notice such things, please let me -know. - -The Readme.v30 contains more details. - -- /dev/midi## devices. -- /dev/sequencer2 - -Since 2.5-beta2 -- Some fine tuning to the GUS v3.7 mixer code. -- Fixed speed limits for the plain SB (1.0 to 2.0). - -Since 2.5-beta -- Fixed OPL-3 detection with SB. Caused problems with PAS16. -- GUS v3.7 mixer support. - -Since 2.4 -- Mixer support for Sound Galaxy NX Pro (define __SGNXPRO__ on your local.h). -- Fixed truncated sound on /dev/dsp when the device is closed. -- Linear volume mode for GUS -- Pitch bends larger than +/- 2 octaves. -- MIDI recording for SB and SB Pro. (Untested). -- Some other fixes. -- SB16 MIDI and DSP drivers only initialized if SB16 actually installed. -- Implemented better detection for OPL-3. This should be useful if you - have an old SB Pro (the non-OPL-3 one) or a SB 2.0 clone which has a OPL-3. -- SVR4.2 support by Ian Hartas. Initial ALPHA TEST version (untested). - -Since 2.3b -- Fixed bug which made it impossible to make long recordings to disk. - Recording was not restarted after a buffer overflow situation. -- Limited mixer support for GUS. -- Numerous improvements to the GUS driver by Andrew Robinson. Including - some click removal etc. - -Since 2.3 -- Fixed some minor bugs in the SB16 driver. - -Since 2.2b -- Full SB16 DSP support. 8/16 bit, mono/stereo -- The SCO and FreeBSD versions should be in sync now. There are some - problems with SB16 and GUS in the FreeBSD versions. - The DMA buffer allocation of the SCO version has been polished but - there could still be some problems. At least it hogs memory. - The DMA channel - configuration method used in the SCO/System is a hack. -- Support for the MPU emulation of the SB16. -- Some big arrays are now allocated boot time. This makes the BSS segment - smaller which makes it possible to use the full driver with - NetBSD. These arrays are not allocated if no suitable sound card is available. -- Fixed a bug in the compute_and_set_volume in gus_wave.c -- Fixed the too fast mono playback problem of SB Pro and PAS16. - -Since 2.2 -- Stereo recording for SB Pro. Somehow it was missing and nobody - had noticed it earlier. -- Minor polishing. -- Interpreting of boot time arguments (sound=) for Linux. -- Breakup of sb_dsp.c. Parts of the code has been moved to - sb_mixer.c and sb_midi.c - -Since 2.1 -- Preliminary support for SB16. - - The SB16 mixer is supported in its native mode. - - Digitized voice capability up to 44.1 kHz/8 bit/mono - (16 bit and stereo support coming in the next release). -- Fixed some bugs in the digitized voice driver for PAS16. -- Proper initialization of the SB emulation of latest PAS16 models. - -- Significantly improved /dev/dsp and /dev/audio support. - - Now supports half duplex mode. It's now possible to record and - playback without closing and reopening the device. - - It's possible to use smaller buffers than earlier. There is a new - ioctl(fd, SNDCTL_DSP_SUBDIVIDE, &n) where n should be 1, 2 or 4. - This call instructs the driver to use smaller buffers. The default - buffer size (0.5 to 1.0 seconds) is divided by n.

If someone owns this - audio card and want to see the kernel support for it, please contact me. - - Audio Excel DSP 16 is an SB pro II, Microsoft Sound System and MPU-401 - compatible card. - It is software-only configurable (no jumpers to hard-set irq/dma/mpu-irq), - so before this module, the only way to configure the DSP under linux was - boot the MS-DOS loading the sound.sys device driver (this driver soft- - configure the sound board hardware by massaging someone of its registers), - and then ctrl-alt-del to boot linux with the DSP configured by the DOS - driver. - - This module works configuring your Audio Excel DSP 16's irq, dma and - mpu-401-irq. The OSS Lite routines rely on the fact that if the - hardware is there, they can detect it. The problem with AEDSP16 is - that no hardware can be found by the probe routines if the sound card - is not configured properly. Sometimes the kernel probe routines can find - an SBPRO even when the card is not configured (this is the standard setup - of the card), but the SBPRO emulation don't work well if the card is not - properly initialized. For this reason - - aedsp16_init_board() - - routine is called before the OSS Lite probe routines try to detect the - hardware. - - NOTE (READ THE NOTE TOO, IT CONTAIN USEFUL INFORMATIONS) - - NOTE: Now it works with SC-6000 and SC-6600 based audio cards. The new cards - have no jumper switch at all. No more WSS or MPU-401 I/O port switches. They - have to be configured by software. - - NOTE: The driver is merged with the new OSS Lite sound driver. It works - as a lowlevel driver. - - The Audio Excel DSP 16 Sound Card emulates both SBPRO and MSS; - the OSS Lite sound driver can be configured for SBPRO and MSS cards - at the same time, but the aedsp16 can't be two cards!! - When we configure it, we have to choose the SBPRO or the MSS emulation - for AEDSP16. We also can install a *REAL* card of the other type (see [1]). - - NOTE: If someone can test the combination AEDSP16+MSS or AEDSP16+SBPRO - please let me know if it works. - - The MPU-401 support can be compiled in together with one of the other - two operating modes. - - NOTE: This is something like plug-and-play: we have only to plug - the AEDSP16 board in the socket, and then configure and compile - a kernel that uses the AEDSP16 software configuration capability. - No jumper setting is needed! - - For example, if you want AEDSP16 to be an SBPro, on irq 10, dma 3 - you have just to make config the OSS Lite package, configuring - the AEDSP16 sound card, then activating the SBPro emulation mode - and at last configuring IRQ and DMA. - Compile the kernel and run it. - - NOTE: This means for SC-6000 cards that you can choose irq and dma, - but not the I/O addresses. To change I/O addresses you have to set - them with jumpers. For SC-6600 cards you have no jumpers so you have - to set up your full card configuration in the make config. - - You can change the irq/dma/mirq settings WITHOUT THE NEED to open - your computer and massage the jumpers (there are no irq/dma/mirq - jumpers to be configured anyway, only I/O BASE values have to be - configured with jumpers) - - For some ununderstandable reason, the card default of irq 7, dma 1, - don't work for me. Seems to be an IRQ or DMA conflict. Under heavy - HDD work, the kernel start to erupt out a lot of messages like: - - 'Sound: DMA timed out - IRQ/DRQ config error?' - - For what I can say, I have NOT any conflict at irq 7 (under linux I'm - using the lp polling driver), and dma line 1 is unused as stated by - /proc/dma. I can suppose this is a bug of AEDSP16. I know my hardware so - I'm pretty sure I have not any conflict, but may be I'm wrong. Who knows! - Anyway a setting of irq 10, dma 3 works really fine. - - NOTE: if someone can use AEDSP16 with irq 7, dma 1, please let me know - the emulation mode, all the installed hardware and the hardware - configuration (irq and dma settings of all the hardware). - - This init module should work with SBPRO+MSS, when one of the two is - the AEDSP16 emulation and the other the real card. (see [1]) - For example: - - AEDSP16 (0x220) in SBPRO emu (0x220) + real MSS + other - AEDSP16 (0x220) in MSS emu + real SBPRO (0x240) + other - - MPU401 should work.

Even if this region is the sbpro I/O ports region, we use this - region to access the control registers of the card, and if emulating - sbpro, I/O sbpro registers too.

We don't need it. Erased the linux/io.h - inclusion too. We rely on os.h - - Used the to get a variable - len string (we are not sure about the len of Copyright string). - This works with any SB and compatible. - - Added the code to request_region at device init (should go in - the main body of voxware). - v0.4 (BETA) - - Better configure.c patch for aedsp16 configuration (better - logic of inclusion of AEDSP16 support) - - Modified the conditional compilation to better support more than - one sound card of the emulated type (read the NOTES above) - - Moved the sb init routine from the attach to the very first - probe in sb_card.c - - Rearrangements and cleanups - - Wiped out some unnecessary code and variables: this is kernel - code so it is better save some TEXT and DATA - - Fixed the request_region code. We must allocate the aedsp16 (sbpro) - I/O ports in any case because they are used to access the DSP - configuration registers and we can not allow anyone to get them. - v0.5 - - cleanups on comments - - prep for diffs against v3.0-proto-950402 - v0.6 - - removed the request_region()s when compiling the MODULE sound.o - because we are not allowed (by the actual voxware structure) to - release_region() - v0.7 (pre ALPHA, not distributed) - - started porting this module to kernel 1.3.84. Dummy probe/attach - routines. - v0.8 (ALPHA) - - attached all the init routines. - v0.9 (BETA) - - Integrated with linux-pre2.0.7 - - Integrated with configuration scripts. - - Cleaned up and beautyfied the code. - v0.9.9 (BETA) - - Thanks to Piercarlo Grandi: corrected the conditonal compilation code. - Now only the code configured is compiled in, with some memory saving. - v0.9.10 - - Integration into the sound/lowlevel/ section of the sound driver. - - Re-organized the code. - v0.9.11 (not distributed) - - Rewritten the init interface-routines to initialize the AEDSP16 in - one shot. - - More cosmetics. - - SC-6600 support. - - More soft/hard configuration. - v0.9.12 - - Refined the v0.9.11 code with conditional compilation to distinguish - between SC-6000 and SC-6600 code. - v1.0.0 - - Prep for merging with OSS Lite and Linux kernel 2.1.13 - - Corrected a bug in request/check/release region calls (thanks to the - new kernel exception handling). - v1.1 - - Revamped for integration with new modularized sound drivers: to enhance - the flexibility of modular version, I have removed all the conditional - compilation for SBPRO, MPU and MSS code. Now it is all managed with - the ae_config structure. - v1.2 - - Module informations added. - - Removed aedsp16_delay_10msec(), now using mdelay(10) - - All data and funcs moved to .*.init section. - v1.3 - Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/09/27 - - got rid of check_region - - Known Problems: - - Audio Excel DSP 16 III don't work with this driver. - - Credits: - Many thanks to Gerald Britton <gbritton@CapAccess.org>. He helped me a - lot in testing the 0.9.11 and 0.9.12 versions of this driver. - - */ - - -#define VERSION "1.3" /* Version of Audio Excel DSP 16 driver */ - -#undef AEDSP16_DEBUG /* Define this to 1 to enable debug code */ -#undef AEDSP16_DEBUG_MORE /* Define this to 1 to enable more debug */ -#undef AEDSP16_INFO /* Define this to 1 to enable info code */ - -#if defined(AEDSP16_DEBUG) -# define DBG(x) printk x -# if defined(AEDSP16_DEBUG_MORE) -# define DBG1(x) printk x -# else -# define DBG1(x) -# endif -#else -# define DBG(x) -# define DBG1(x) -#endif - -/* - * Misc definitions - */ -#define TRUE 1 -#define FALSE 0 - -/* - * Region Size for request/check/release region. - */ -#define IOBASE_REGION_SIZE 0x10 - -/* - * Hardware related defaults - */ -#define DEF_AEDSP16_IOB 0x220 /* 0x220(default) 0x240 */ -#define DEF_AEDSP16_IRQ 7 /* 5 7(default) 9 10 11 */ -#define DEF_AEDSP16_MRQ 0 /* 5 7 9 10 0(default), 0 means disable */ -#define DEF_AEDSP16_DMA 1 /* 0 1(default) 3 */ - -/* - * Commands of AEDSP16's DSP (SBPRO+special). - * Some of them are COMMAND_xx, in the future they may change. - */ -#define WRITE_MDIRQ_CFG 0x50 /* Set M&I&DRQ mask (the real config) */ -#define COMMAND_52 0x52 /* */ -#define READ_HARD_CFG 0x58 /* Read Hardware Config (I/O base etc) */ -#define COMMAND_5C 0x5c /* */ -#define COMMAND_60 0x60 /* */ -#define COMMAND_66 0x66 /* */ -#define COMMAND_6C 0x6c /* */ -#define COMMAND_6E 0x6e /* */ -#define COMMAND_88 0x88 /* */ -#define DSP_INIT_MSS 0x8c /* Enable Microsoft Sound System mode */ -#define COMMAND_C5 0xc5 /* */ -#define GET_DSP_VERSION 0xe1 /* Get DSP Version */ -#define GET_DSP_COPYRIGHT 0xe3 /* Get DSP Copyright */ - -/* - * Offsets of AEDSP16 DSP I/O ports.

The - * documentation about ES1888 (rev C, october '95) claims that ES1888 has - * the following features ES1688 doesn't have: - * - 6 bit master volume - * - Full Duplex - * So ES1688 apparently doesn't have 6 bit master volume control, but the - * ES1688 does have RECLEV control. Makes me wonder: does ES688 have it too? - * Without RECLEV ES688 won't be much fun I guess. - * - * From the ES1888 (rev C, october '95) documentation I got the impression - * that registers 0x68 to 0x6e don't exist which means: no recording volume - * controls. To my surprise the ES888 documentation (1/14/96) claims that - * ES888 does have these record mixer registers, but that ES1888 doesn't have - * 0x69 and 0x6b. So the rest should be there. - * - * I'm trying to get ES1887 Full Duplex. Audio 2 is playback only, while Audio 2 - * is both record and playback. I think I should use Audio 2 for all playback. - * - * The documentation is an adventure: it's close but not fully accurate. I - * found out that after a reset some registers are *NOT* reset, though the - * docs say the would be. Interesting ones are 0x7f, 0x7d and 0x7a. They are - * related to the Audio 2 channel. I also was surprised about the consequences - * of writing 0x00 to 0x7f (which should be done by reset): The ES1887 moves - * into ES1888 mode. This means that it claims IRQ 11, which happens to be my - * ISDN adapter. Needless to say it no longer worked. I now understand why - * after rebooting 0x7f already was 0x05, the value of my choice: the BIOS - * did it. - * - * Oh, and this is another trap: in ES1887 docs mixer register 0x70 is - * described as if it's exactly the same as register 0xa1. This is *NOT* true. - * The description of 0x70 in ES1869 docs is accurate however. - * Well, the assumption about ES1869 was wrong: register 0x70 is very much - * like register 0xa1, except that bit 7 is always 1, whatever you want - * it to be. - * - * When using audio 2 mixer register 0x72 seems te be meaningless. Only 0xa2 - * has effect. - * - * Software reset not being able to reset all registers is great! Especially - * the fact that register 0x78 isn't reset is great when you wanna change back - * to single dma operation (simplex): audio 2 is still operational, and uses - * the same dma as audio 1: your ess changes into a funny echo machine. - * - * Received the news that ES1688 is detected as a ES1788. Did some thinking: - * the ES1887 detection scheme suggests in step 2 to try if bit 3 of register - * 0x64 can be changed. This is inaccurate, first I inverted the * check: "If - * can be modified, it's a 1688", which lead to a correct detection - * of my ES1887. It resulted however in bad detection of 1688 (reported by mail) - * and 1868 (if no PnP detection first): they result in a 1788 being detected. - * I don't have docs on 1688, but I do have docs on 1868: The documentation is - * probably inaccurate in the fact that I should check bit 2, not bit 3. This - * is what I do now. - */ - -/* - * About recognition of ESS chips - * - * The distinction of ES688, ES1688, ES1788, ES1887 and ES1888 is described in - * a (preliminary ??) datasheet on ES1887. Its aim is to identify ES1887, but - * during detection the text claims that "this chip may be ..." when a step - * fails. This scheme is used to distinct between the above chips. - * It appears however that some PnP chips like ES1868 are recognized as ES1788 - * by the ES1887 detection scheme. These PnP chips can be detected in another - * way however: ES1868, ES1869 and ES1878 can be recognized (full proof I think) - * by repeatedly reading mixer register 0x40. This is done by ess_identify in - * sb_common.c. - * This results in the following detection steps: - * - distinct between ES688 and ES1688+ (as always done in this driver) - * if ES688 we're ready - * - try to detect ES1868, ES1869 or ES1878 - * if successful we're ready - * - try to detect ES1888, ES1887 or ES1788 - * if successful we're ready - * - Dunno. Must be 1688. Will do in general - * - * About RECLEV support: - * - * The existing ES1688 support didn't take care of the ES1688+ recording - * levels very well. Whenever a device was selected (recmask) for recording - * its recording level was loud, and it couldn't be changed. The fact that - * internal register 0xb4 could take care of RECLEV, didn't work meaning until - * its value was restored every time the chip was reset; this reset the - * value of 0xb4 too. I guess that's what 4front also had (have?) trouble with. - * - * About ES1887 support: - * - * The ES1887 has separate registers to control the recording levels, for all - * inputs. The ES1887 specific software makes these levels the same as their - * corresponding playback levels, unless recmask says they aren't recorded. In - * the latter case the recording volumes are 0. - * Now recording levels of inputs can be controlled, by changing the playback - * levels.
