  35    This module started to configure the Audio Excel DSP 16 Sound Card.
  36    Now works with the SC-6000 (old aedsp16) and new SC-6600 based cards.
  37
  38    NOTE: I have NO idea about Audio Excel DSP 16 III. If someone owns this
  39    audio card and want to see the kernel support for it, please contact me.
  40
  41    Audio Excel DSP 16 is an SB pro II, Microsoft Sound System and MPU-401
  42    compatible card.
  43    It is software-only configurable (no jumpers to hard-set irq/dma/mpu-irq),
  44    so before this module, the only way to configure the DSP under linux was
  45    boot the MS-DOS loading the sound.sys device driver (this driver soft-
  46    configure the sound board hardware by massaging someone of its registers),
  47    and then ctrl-alt-del to boot linux with the DSP configured by the DOS
  48    driver.
  49
  50    This module works configuring your Audio Excel DSP 16's irq, dma and
  51    mpu-401-irq. The OSS Lite routines rely on the fact that if the
  52    hardware is there, they can detect it. The problem with AEDSP16 is
  53    that no hardware can be found by the probe routines if the sound card
  54    is not configured properly. Sometimes the kernel probe routines can find
  55    an SBPRO even when the card is not configured (this is the standard setup
  56    of the card), but the SBPRO emulation don't work well if the card is not
  57    properly initialized. For this reason
  58
  59    aedsp16_init_board()
  60
  61    routine is called before the OSS Lite probe routines try to detect the
  62    hardware.
  63
  64    NOTE (READ THE NOTE TOO, IT CONTAIN USEFUL INFORMATIONS)
  65
  66    NOTE: Now it works with SC-6000 and SC-6600 based audio cards. The new cards
  67    have no jumper switch at all. No more WSS or MPU-401 I/O port switches. They
  68    have to be configured by software.
  69
  70    NOTE: The driver is merged with the new OSS Lite sound driver. It works
  71    as a lowlevel driver.
  72
  73    The Audio Excel DSP 16 Sound Card emulates both SBPRO and MSS;
  74    the OSS Lite sound driver can be configured for SBPRO and MSS cards
  75    at the same time, but the aedsp16 can't be two cards!!
  76    When we configure it, we have to choose the SBPRO or the MSS emulation
  77    for AEDSP16. We also can install a *REAL* card of the other type (see [1]).
  78
  79    NOTE: If someone can test the combination AEDSP16+MSS or AEDSP16+SBPRO
  80    please let me know if it works.
  81
  82    The MPU-401 support can be compiled in together with one of the other
  83    two operating modes.
  84
  85    NOTE: This is something like plug-and-play: we have only to plug
  86    the AEDSP16 board in the socket, and then configure and compile
  87    a kernel that uses the AEDSP16 software configuration capability.
  88    No jumper setting is needed!
  89
  90    For example, if you want AEDSP16 to be an SBPro, on irq 10, dma 3
  91    you have just to make config the OSS Lite package, configuring
  92    the AEDSP16 sound card, then activating the SBPro emulation mode
  93    and at last configuring IRQ and DMA.
  94    Compile the kernel and run it.
  95
  96    NOTE: This means for SC-6000 cards that you can choose irq and dma,
  97    but not the I/O addresses. To change I/O addresses you have to set
  98    them with jumpers. For SC-6600 cards you have no jumpers so you have
  99    to set up your full card configuration in the make config.
 100
 101    You can change the irq/dma/mirq settings WITHOUT THE NEED to open
 102    your computer and massage the jumpers (there are no irq/dma/mirq
 103    jumpers to be configured anyway, only I/O BASE values have to be
 104    configured with jumpers)
 105
 106    For some ununderstandable reason, the card default of irq 7, dma 1,
 107    don't work for me. Seems to be an IRQ or DMA conflict. Under heavy
 108    HDD work, the kernel start to erupt out a lot of messages like:
 109
 110    'Sound: DMA timed out - IRQ/DRQ config error?'
 111
 112    For what I can say, I have NOT any conflict at irq 7 (under linux I'm
 113    using the lp polling driver), and dma line 1 is unused as stated by
 114    /proc/dma. I can suppose this is a bug of AEDSP16. I know my hardware so
 115    I'm pretty sure I have not any conflict, but may be I'm wrong. Who knows!
 116    Anyway a setting of irq 10, dma 3 works really fine.
 117
 118    NOTE: if someone can use AEDSP16 with irq 7, dma 1, please let me know
 119    the emulation mode, all the installed hardware and the hardware
 120    configuration (irq and dma settings of all the hardware).
 121
 122    This init module should work with SBPRO+MSS, when one of the two is
 123    the AEDSP16 emulation and the other the real card. (see [1])
 124    For example:
 125
 126    AEDSP16 (0x220) in SBPRO emu (0x220) + real MSS + other
 127    AEDSP16 (0x220) in MSS emu + real SBPRO (0x240) + other
 128
 129    MPU401 should work. (see [2])

 144    TODO, WISHES AND TECH
 145
 146    - About I/O ports allocation -
 147
 148    Request the 2x0h region (port base) in any case if we are using this card.
 149
 150    NOTE: the "aedsp16 (base)" string with which we are requesting the aedsp16
 151    port base region (see code) does not mean necessarily that we are emulating
 152    sbpro.  Even if this region is the sbpro I/O ports region, we use this
 153    region to access the control registers of the card, and if emulating
 154    sbpro, I/O sbpro registers too. If we are emulating MSS, the sbpro
 155    registers are not used, in no way, to emulate an sbpro: they are
 156    used only for configuration purposes.

 158    Started Fri Mar 17 16:13:18 MET 1995
 159
 160    v0.1 (ALPHA, was an user-level program called AudioExcelDSP16.c)
 161    - Initial code.
 162    v0.2 (ALPHA)
 163    - Cleanups.
 164    - Integrated with Linux voxware v 2.90-2 kernel sound driver.
 165    - SoundBlaster Pro mode configuration.
 166    - Microsoft Sound System mode configuration.
 167    - MPU-401 mode configuration.
 168    v0.3 (ALPHA)
 169    - Cleanups.
 170    - Rearranged the code to let aedsp16_init_board be more general.
 171    - Erased the REALLY_SLOW_IO. We don't need it. Erased the linux/io.h
 172    inclusion too. We rely on os.h
 173    - Used the  to get a variable
 174    len string (we are not sure about the len of Copyright string).
 175    This works with any SB and compatible.
 176    - Added the code to request_region at device init (should go in
 177    the main body of voxware).
 178    v0.4 (BETA)
 179    - Better configure.c patch for aedsp16 configuration (better
 180    logic of inclusion of AEDSP16 support)
 181    - Modified the conditional compilation to better support more than
 182    one sound card of the emulated type (read the NOTES above)
 183    - Moved the sb init routine from the attach to the very first
 184    probe in sb_card.c
 185    - Rearrangements and cleanups
 186    - Wiped out some unnecessary code and variables: this is kernel
 187    code so it is better save some TEXT and DATA
 188    - Fixed the request_region code. We must allocate the aedsp16 (sbpro)
 189    I/O ports in any case because they are used to access the DSP
 190    configuration registers and we can not allow anyone to get them.
 191    v0.5
 192    - cleanups on comments
 193    - prep for diffs against v3.0-proto-950402
 194    v0.6
 195    - removed the request_region()s when compiling the MODULE sound.o
 196    because we are not allowed (by the actual voxware structure) to
 197    release_region()
 198    v0.7 (pre ALPHA, not distributed)
 199    - started porting this module to kernel 1.3.84. Dummy probe/attach
 200    routines.
 201    v0.8 (ALPHA)
 202    - attached all the init routines.
 203    v0.9 (BETA)
 204    - Integrated with linux-pre2.0.7
 205    - Integrated with configuration scripts.
 206    - Cleaned up and beautyfied the code.
 207    v0.9.9 (BETA)
 208    - Thanks to Piercarlo Grandi: corrected the conditonal compilation code.
 209      Now only the code configured is compiled in, with some memory saving.
 210    v0.9.10
 211    - Integration into the sound/lowlevel/ section of the sound driver.
 212    - Re-organized the code.
 213    v0.9.11 (not distributed)
 214    - Rewritten the init interface-routines to initialize the AEDSP16 in
 215      one shot.
 216    - More cosmetics.
 217    - SC-6600 support.
 218    - More soft/hard configuration.
 219    v0.9.12
 220    - Refined the v0.9.11 code with conditional compilation to distinguish
 221      between SC-6000 and SC-6600 code.
 222    v1.0.0
 223    - Prep for merging with OSS Lite and Linux kernel 2.1.13
 224    - Corrected a bug in request/check/release region calls (thanks to the
 225      new kernel exception handling).
 226    v1.1
 227    - Revamped for integration with new modularized sound drivers: to enhance
 228      the flexibility of modular version, I have removed all the conditional
 229      compilation for SBPRO, MPU and MSS code. Now it is all managed with
 230      the ae_config structure.
 231    v1.2
 232    - Module informations added.
 233    - Removed aedsp16_delay_10msec(), now using mdelay(10)
 234    - All data and funcs moved to .*.init section.
 235    v1.3
 236    Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/09/27
 237    - got rid of check_region
 238
 239    Known Problems:
 240    - Audio Excel DSP 16 III don't work with this driver.
 241
 242    Credits:
 243    Many thanks to Gerald Britton <gbritton@CapAccess.org>. He helped me a
 244    lot in testing the 0.9.11 and 0.9.12 versions of this driver.
