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])

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.

2008-12-29 14:14:56 -07:00
|
|
|
v0.1 (ALPHA, was a user-level program called AudioExcelDSP16.c)
|
2005-04-16 16:20:36 -06:00
|
|
|
- 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.
