These devices require more time to "recover" from processing - of each fragment. - -Since 3.5.4-beta6/7 -- There seems to be problems in the OPTi 82C930 so cards based on this - chip don't necessarily work yet. There are problems in detecting the - MIDI interface. 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. There is now - just one /dev/dsp# device which is used both for code download and audio. - -Since 3.5.4.beta4 -- Minor changes. - -Since 3.5.4-beta2 -- Fixed silent playback with ESS 688/1688. -- Got SB16 to work without the 16 bit DMA channel (only the 8 bit one - is required for 8 and 16 bit modes). -- Added the "lowlevel" subdirectory for additional low level drivers that - are not part of USS core. See lowlevel/README for more info. -- Included support for ACI mixer (by Markus Kuhn). ACI is a mixer used in - miroPCM sound cards. See lowlevel/aci.readme for more info. -- Support for Aztech Washington chipset (AZT2316 ASIC). - -Since 3.5.4-beta1 -- Reduced clicking with AD1848. -- Support for OPTi 82C930. Only half duplex at this time. 16 bit playback - is sometimes just white noise (occurs randomly). - -Since 3.5.2 -- Major changes to the SB/Jazz16/ESS driver (most parts rewritten). - The most noticeable new feature is support for multiple SB cards at the same - time. -- Renamed sb16_midi.c to uart401.c. Also modified it to work also with - other MPU401 UART compatible cards than SB16/ESS/Jazz. -- Some changes which reduce clicking in audio playback. -- Copying policy is now GPL. - -Since 3.5.1 -- TB Maui initialization support -Since 3.5 -- Improved handling of playback underrun situations. - -Since 3.5-beta10 -- Bug fixing - -Since 3.5-beta9 -- Fixed for compatibility with Linux 1.3.70 and later. -- Changed boot time passing of 16 bit DMA channel number to SB driver. - -Since 3.5-beta8 -- Minor changes - -Since 3.5-beta7 -- enhancements to configure program (by Jeff Tranter): - - prompts are in same format as 1.3.x Linux kernel config program - - on-line help for each question - - fixed some compile warnings detected by gcc/g++ -Wall - - minor grammatical changes to prompts - -Since 3.5-beta6 -- Fixed bugs in mmap() support. -- Minor changes to Maui driver. - -Since 3.5-beta5 -- Fixed crash after recording with ESS688. It's generally a good - idea to stop inbound DMA transfers before freeing the memory - buffer. -- Fixed handling of AD1845 codec (for example Shuttle Sound System). -- Few other fixes. - -Since 3.5-beta4 -- Fixed bug in handling of uninitialized instruments with GUS. - -Since 3.5-beta3 -- Few changes which decrease popping at end/beginning of audio playback. - -Since 3.5-beta2 -- Removed MAD16+CS4231 hack made in previous version since it didn't - help. -- Fixed the above bug in proper way and in proper place. 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. Should be called - immediately after opening the device. - -Since 2.0 -Just cosmetic changes. diff --git a/sound/oss/Kconfig b/sound/oss/Kconfig deleted file mode 100644 index 4033fe58f0cf..000000000000 --- a/sound/oss/Kconfig +++ /dev/null @@ -1,533 +0,0 @@ -# 18 Apr 1998, Michael Elizabeth Chastain, <mailto:mec@shout.net> -# More hacking for modularisation. -# -# Prompt user for primary drivers. - -config SOUND_BCM_CS4297A - tristate "Crystal Sound CS4297a (for Swarm)" - depends on SIBYTE_SWARM - help - The BCM91250A has a Crystal CS4297a on synchronous serial - port B (in addition to the DB-9 serial port).

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.

If you have additional info, - * please enlighten me (fokkensr@vertis.nl)! - * - * I had the impression that ES1688 also has 6 bit master volume control. 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.
