- READ THIS
-
- This module is intended for Audio Excel DSP 16 Sound Card.
-
- 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-BAU 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 DOG
- driver.
-
- This module works configuring your Audio Excel DSP 16's
- irq, dma and mpu-401-irq. The voxware probe 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 well configured. 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
-
- InitAEDSP16_...()
-
- routines are called before the voxware probe routines try to detect the
- hardware.
-
- NOTE (READ THE NOTE TOO, IT CONTAIN USEFUL INFORMATIONS)
-
- The Audio Excel DSP 16 Sound Card emulates both SBPRO and MSS;
- the voxware 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], not tested but I can't see any reason for it to fail).
-
- 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.
-
- The board configuration calls, are in the probe_...() routines because
- we have to configure the board before probing it for a particular
- hardware. After card configuration, we can probe the hardware.
-
- 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 voxware package, configuring
- the SBPro sound card with that parameters, then when configure
- asks if you have an AEDSP16, answer yes. That's it.
- Compile the kernel and run it.
-
- NOTE: This means 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.
-
- NOTE: InitAEDSP16_...() routines get as parameter the hw_config,
- the hardware configuration of the - to be configured - board.
- The InitAEDSP16() routine, configure the board following our
- wishes, that are in the hw_config structure.
-
- 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 port ones 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 [1])
-
- [1] Not tested by me for lack of hardware.
-
- TODO, WISHES AND TECH
-
- May be there's lot of redundant delays, but for now I want to leave it
- this way.
-
- Should be interesting eventually write down a new ioctl for the
- AEDSP16, to let the suser() change the irq/dma/mirq on the fly.
- The thing is not trivial.
- In the real world, there's no need to have such an ioctl because
- when we configure the kernel for compile, we can choose the config
- parameters. If we change our mind, we can easily re-config the kernel
- and re-compile.
- Why let the suser() change the config parameters on the fly ?
- If anyone have a reasonable answer to this question, I will write down
- the code to do it.
-
- More integration with voxware, using voxware low level routines to
- read-write DSP is not possible because you may want to have MSS
- support and in that case we can not rely on the functions included
- in sb_dsp.c to control 0x2yy I/O ports. I will continue to use my
- own I/O functions.
-
- - About I/O ports allocation -
-
- The request_region should be done at device probe in every sound card
- module. This module is not the best site for requesting regions.
- When the request_region code will be added to the main modules such as
- sb, adlib, gus, ad1848, etc, the requesting code in this module should
- go away.
-
- I think the request regions should be done this way:
-
- if (check_region(...))
- return ERR; // I/O region already reserved
- device_probe(...);
- device_attach(...);
- request_region(...); // reserve only when we are sure all is okay
-
- Request the 2x0h region in any case if we are using this card.
-
- NOTE: the "(SBPro)" string with which we are requesting the AEDSP16 region
- (see code) does not mean necessarily that we are emulating SBPro.
- It mean that the 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.
-
- Someone pointed out that should be possible use both the SBPRO and MSS
- modes because the sound card have all the two chipsets, supposing that
- the card is really two cards. I have tried something to have the two
- modes work together, but, for some reason unknown to me, without success.
-
- I think all the soft-config only cards have an init sequence similar to
- this. If you have a card that is not an AEDSP16, you can try to start
- with this module changing it (mainly in the CMD? I think) to fit your
- needs.

-
- 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.
- - Sound Blaster Pro mode configuration.
- - Microsoft Sound System mode configuration.
- - MPU-401 mode configuration.
- v0.3 (ALPHA)
- - Cleanups.
- - Rearranged the code to let InitAEDSP16 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()
