| 34 | |
| 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. |

Frederik Schwarzer | 0211a9c8 | 2008-12-29 22:14:56 +0100 | [diff] [blame] | 160 | v0.1 (ALPHA, was a user-level program called AudioExcelDSP16.c) |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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. |
