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>.
