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. If we are emulating MSS, the sbpro - registers are not used, in no way, to emulate an sbpro: they are - used only for configuration purposes. - - Started Fri Mar 17 16:13:18 MET 1995 - - v0.1 (ALPHA, was a user-level program called AudioExcelDSP16.c) - - Initial code. - v0.2 (ALPHA) - - Cleanups. - - Integrated with Linux voxware v 2.90-2 kernel sound driver. - - SoundBlaster Pro mode configuration. - - Microsoft Sound System mode configuration. - - MPU-401 mode configuration. - v0.3 (ALPHA) - - Cleanups. - - Rearranged the code to let aedsp16_init_board be more general. - - Erased the REALLY_SLOW_IO. 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.
