+
+ 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])

+
+ 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 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.
