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. |
157 | |
158 | Started Fri Mar 17 16:13:18 MET 1995 |
159 | |
160 | v0.1 (ALPHA, was a 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. |
