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

155 From: Mr S J Greenaway <sjg95@unixfe.rl.ac.uk>
158 Just to let you know got my Audio Excel (emulating a MSS) working
159 with my original SB16, thanks for the driver!
163 [2] Not tested by me for lack of hardware.
165 TODO, WISHES AND TECH
167 - About I/O ports allocation -
169 Request the 2x0h region (port base) in any case if we are using this card.
171 NOTE: the "aedsp16 (base)" string with which we are requesting the aedsp16
172 port base region (see code) does not mean necessarily that we are emulating
173 sbpro. Even if this region is the sbpro I/O ports region, we use this
174 region to access the control registers of the card, and if emulating
175 sbpro, I/O sbpro registers too. If we are emulating MSS, the sbpro
176 registers are not used, in no way, to emulate an sbpro: they are
177 used only for configuration purposes.
179 Started Fri Mar 17 16:13:18 MET 1995
181 v0.1 (ALPHA, was an user-level program called AudioExcelDSP16.c)
185 - Integrated with Linux voxware v 2.90-2 kernel sound driver.
186 - SoundBlaster Pro mode configuration.
187 - Microsoft Sound System mode configuration.
188 - MPU-401 mode configuration.
191 - Rearranged the code to let aedsp16_init_board be more general.
192 - Erased the REALLY_SLOW_IO. We don't need it. Erased the linux/io.h
193 inclusion too. We rely on os.h
194 - Used the to get a variable
195 len string (we are not sure about the len of Copyright string).
196 This works with any SB and compatible.
197 - Added the code to request_region at device init (should go in
198 the main body of voxware).
200 - Better configure.c patch for aedsp16 configuration (better
201 logic of inclusion of AEDSP16 support)
202 - Modified the conditional compilation to better support more than
203 one sound card of the emulated type (read the NOTES above)
204 - Moved the sb init routine from the attach to the very first
206 - Rearrangements and cleanups
207 - Wiped out some unnecessary code and variables: this is kernel
208 code so it is better save some TEXT and DATA
209 - Fixed the request_region code. We must allocate the aedsp16 (sbpro)
210 I/O ports in any case because they are used to access the DSP
211 configuration registers and we can not allow anyone to get them.
213 - cleanups on comments
214 - prep for diffs against v3.0-proto-950402
216 - removed the request_region()s when compiling the MODULE sound.o
217 because we are not allowed (by the actual voxware structure) to
219 v0.7 (pre ALPHA, not distributed)
220 - started porting this module to kernel 1.3.84. Dummy probe/attach
223 - attached all the init routines.
225 - Integrated with linux-pre2.0.7
226 - Integrated with configuration scripts.
227 - Cleaned up and beautyfied the code.
229 - Thanks to Piercarlo Grandi: corrected the conditonal compilation code.
230 Now only the code configured is compiled in, with some memory saving.
232 - Integration into the sound/lowlevel/ section of the sound driver.
233 - Re-organized the code.
234 v0.9.11 (not distributed)
235 - Rewritten the init interface-routines to initialize the AEDSP16 in
239 - More soft/hard configuration.
241 - Refined the v0.9.11 code with conditional compilation to distinguish
242 between SC-6000 and SC-6600 code.
244 - Prep for merging with OSS Lite and Linux kernel 2.1.13
245 - Corrected a bug in request/check/release region calls (thanks to the
246 new kernel exception handling).
248 - Revamped for integration with new modularized sound drivers: to enhance
249 the flexibility of modular version, I have removed all the conditional
250 compilation for SBPRO, MPU and MSS code. Now it is all managed with
251 the ae_config structure.
253 - Module informations added.
254 - Removed aedsp16_delay_10msec(), now using mdelay(10)
255 - All data and funcs moved to .*.init section.
258 - Audio Excel DSP 16 III don't work with this driver.
261 Many thanks to Gerald Britton <gbritton@CapAccess.org>. He helped me a
262 lot in testing the 0.9.11 and 0.9.12 versions of this driver.
