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])

143
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 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.
