43 This module started to configure the Audio Excel DSP 16 Sound Card.
44 Now works with the SC-6000 (old aedsp16) and new SC-6600 based cards.
45
46 NOTE: I have NO idea about Audio Excel DSP 16 III. If someone owns this
47 audio card and want to see the kernel support for it, please contact me.
48
49 Audio Excel DSP 16 is an SB pro II, Microsoft Sound System and MPU-401
50 compatible card.
51 It is software-only configurable (no jumpers to hard-set irq/dma/mpu-irq),
52 so before this module, the only way to configure the DSP under linux was
53 boot the MS-DOS loading the sound.sys device driver (this driver soft-
54 configure the sound board hardware by massaging someone of its registers),
55 and then ctrl-alt-del to boot linux with the DSP configured by the DOS
56 driver.
57
58 This module works configuring your Audio Excel DSP 16's irq, dma and
59 mpu-401-irq. The OSS Lite routines rely on the fact that if the
60 hardware is there, they can detect it. The problem with AEDSP16 is
61 that no hardware can be found by the probe routines if the sound card
62 is not configured properly. Sometimes the kernel probe routines can find
63 an SBPRO even when the card is not configured (this is the standard setup
64 of the card), but the SBPRO emulation don't work well if the card is not
65 properly initialized. For this reason
66
67 aedsp16_init_board()
68
69 routine is called before the OSS Lite probe routines try to detect the
70 hardware.
71
72 NOTE (READ THE NOTE TOO, IT CONTAIN USEFUL INFORMATIONS)
73
74 NOTE: Now it works with SC-6000 and SC-6600 based audio cards. The new cards
75 have no jumper switch at all. No more WSS or MPU-401 I/O port switches. They
76 have to be configured by software.
77
78 NOTE: The driver is merged with the new OSS Lite sound driver. It works
79 as a lowlevel driver.
80
81 The Audio Excel DSP 16 Sound Card emulates both SBPRO and MSS;
82 the OSS Lite sound driver can be configured for SBPRO and MSS cards
83 at the same time, but the aedsp16 can't be two cards!!
84 When we configure it, we have to choose the SBPRO or the MSS emulation
85 for AEDSP16. We also can install a *REAL* card of the other type (see [1]).
86
87 NOTE: If someone can test the combination AEDSP16+MSS or AEDSP16+SBPRO
88 please let me know if it works.
89
90 The MPU-401 support can be compiled in together with one of the other
91 two operating modes.
92
93 NOTE: This is something like plug-and-play: we have only to plug
94 the AEDSP16 board in the socket, and then configure and compile
95 a kernel that uses the AEDSP16 software configuration capability.
96 No jumper setting is needed!
97
98 For example, if you want AEDSP16 to be an SBPro, on irq 10, dma 3
99 you have just to make config the OSS Lite package, configuring
100 the AEDSP16 sound card, then activating the SBPro emulation mode
101 and at last configuring IRQ and DMA.
102 Compile the kernel and run it.
103
104 NOTE: This means for SC-6000 cards that you can choose irq and dma,
105 but not the I/O addresses. To change I/O addresses you have to set
106 them with jumpers. For SC-6600 cards you have no jumpers so you have
107 to set up your full card configuration in the make config.
108
109 You can change the irq/dma/mirq settings WITHOUT THE NEED to open
110 your computer and massage the jumpers (there are no irq/dma/mirq
111 jumpers to be configured anyway, only I/O BASE values have to be
112 configured with jumpers)
113
114 For some ununderstandable reason, the card default of irq 7, dma 1,
115 don't work for me. Seems to be an IRQ or DMA conflict. Under heavy
116 HDD work, the kernel start to erupt out a lot of messages like:
117
118 'Sound: DMA timed out - IRQ/DRQ config error?'
119
120 For what I can say, I have NOT any conflict at irq 7 (under linux I'm
121 using the lp polling driver), and dma line 1 is unused as stated by
122 /proc/dma. I can suppose this is a bug of AEDSP16. I know my hardware so
123 I'm pretty sure I have not any conflict, but may be I'm wrong. Who knows!
124 Anyway a setting of irq 10, dma 3 works really fine.
125
126 NOTE: if someone can use AEDSP16 with irq 7, dma 1, please let me know
127 the emulation mode, all the installed hardware and the hardware
128 configuration (irq and dma settings of all the hardware).
129
130 This init module should work with SBPRO+MSS, when one of the two is
131 the AEDSP16 emulation and the other the real card. (see [1])
132 For example:
133
134 AEDSP16 (0x220) in SBPRO emu (0x220) + real MSS + other
135 AEDSP16 (0x220) in MSS emu + real SBPRO (0x240) + other
136
137 MPU401 should work. (see [2])

152 TODO, WISHES AND TECH
153
154 - About I/O ports allocation -
155
156 Request the 2x0h region (port base) in any case if we are using this card.
157
158 NOTE: the "aedsp16 (base)" string with which we are requesting the aedsp16
159 port base region (see code) does not mean necessarily that we are emulating
160 sbpro. Even if this region is the sbpro I/O ports region, we use this
161 region to access the control registers of the card, and if emulating
162 sbpro, I/O sbpro registers too. If we are emulating MSS, the sbpro
163 registers are not used, in no way, to emulate an sbpro: they are
164 used only for configuration purposes.

166 Started Fri Mar 17 16:13:18 MET 1995
167
168 v0.1 (ALPHA, was an user-level program called AudioExcelDSP16.c)
169 - Initial code.
170 v0.2 (ALPHA)
171 - Cleanups.
172 - Integrated with Linux voxware v 2.90-2 kernel sound driver.
173 - SoundBlaster Pro mode configuration.
174 - Microsoft Sound System mode configuration.
175 - MPU-401 mode configuration.
176 v0.3 (ALPHA)
177 - Cleanups.
178 - Rearranged the code to let aedsp16_init_board be more general.
179 - Erased the REALLY_SLOW_IO. We don't need it. Erased the linux/io.h
180 inclusion too. We rely on os.h
181 - Used the to get a variable
182 len string (we are not sure about the len of Copyright string).
183 This works with any SB and compatible.
184 - Added the code to request_region at device init (should go in
185 the main body of voxware).
186 v0.4 (BETA)
187 - Better configure.c patch for aedsp16 configuration (better
188 logic of inclusion of AEDSP16 support)
189 - Modified the conditional compilation to better support more than
190 one sound card of the emulated type (read the NOTES above)
191 - Moved the sb init routine from the attach to the very first
192 probe in sb_card.c
193 - Rearrangements and cleanups
194 - Wiped out some unnecessary code and variables: this is kernel
195 code so it is better save some TEXT and DATA
196 - Fixed the request_region code. We must allocate the aedsp16 (sbpro)
197 I/O ports in any case because they are used to access the DSP
198 configuration registers and we can not allow anyone to get them.
199 v0.5
200 - cleanups on comments
201 - prep for diffs against v3.0-proto-950402
202 v0.6
203 - removed the request_region()s when compiling the MODULE sound.o
204 because we are not allowed (by the actual voxware structure) to
205 release_region()
206 v0.7 (pre ALPHA, not distributed)
207 - started porting this module to kernel 1.3.84. Dummy probe/attach
208 routines.
209 v0.8 (ALPHA)
210 - attached all the init routines.
211 v0.9 (BETA)
212 - Integrated with linux-pre2.0.7
213 - Integrated with configuration scripts.
214 - Cleaned up and beautyfied the code.
215 v0.9.9 (BETA)
216 - Thanks to Piercarlo Grandi: corrected the conditonal compilation code.
217 Now only the code configured is compiled in, with some memory saving.
218 v0.9.10
219 - Integration into the sound/lowlevel/ section of the sound driver.
220 - Re-organized the code.
221 v0.9.11 (not distributed)
222 - Rewritten the init interface-routines to initialize the AEDSP16 in
223 one shot.
224 - More cosmetics.
225 - SC-6600 support.
226 - More soft/hard configuration.
227 v0.9.12
228 - Refined the v0.9.11 code with conditional compilation to distinguish
229 between SC-6000 and SC-6600 code.
230 v1.0.0
231 - Prep for merging with OSS Lite and Linux kernel 2.1.13
232 - Corrected a bug in request/check/release region calls (thanks to the
233 new kernel exception handling).
234 v1.1
235 - Revamped for integration with new modularized sound drivers: to enhance
236 the flexibility of modular version, I have removed all the conditional
237 compilation for SBPRO, MPU and MSS code. Now it is all managed with
238 the ae_config structure.
239 v1.2
240 - Module informations added.
241 - Removed aedsp16_delay_10msec(), now using mdelay(10)
242 - All data and funcs moved to .*.init section.
243 v1.3
244 Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/09/27
245 - got rid of check_region
246
247 Known Problems:
248 - Audio Excel DSP 16 III don't work with this driver.
249
250 Credits:
251 Many thanks to Gerald Britton <gbritton@CapAccess.org>. He helped me a
252 lot in testing the 0.9.11 and 0.9.12 versions of this driver.
