- READ THIS
-
- This module started to configure the Audio Excel DSP 16 Sound Card.
- Now works with the SC-6000 (old aedsp16) and new SC-6600 based cards.
-
- NOTE: I have NO idea about Audio Excel DSP 16 III. 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. (see [2])

- [...]
- Just to let you know got my Audio Excel (emulating a MSS) working
- with my original SB16, thanks for the driver!

- [2] Not tested by me for lack of hardware.
-
- TODO, WISHES AND TECH
-
- - About I/O ports allocation -
-
- Request the 2x0h region (port base) in any case if we are using this card.
-
- NOTE: the "aedsp16 (base)" string with which we are requesting the aedsp16
- port base region (see code) does not mean necessarily that we are emulating
- sbpro. 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 an 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.
-
- 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.
