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

143 From: Mr S J Greenaway <sjg95@unixfe.rl.ac.uk>
146 Just to let you know got my Audio Excel (emulating a MSS) working
147 with my original SB16, thanks for the driver!
151 [2] Not tested by me for lack of hardware.
153 TODO, WISHES AND TECH
155 - About I/O ports allocation -
157 Request the 2x0h region (port base) in any case if we are using this card.
159 NOTE: the "aedsp16 (base)" string with which we are requesting the aedsp16
160 port base region (see code) does not mean necessarily that we are emulating
161 sbpro. Even if this region is the sbpro I/O ports region, we use this
162 region to access the control registers of the card, and if emulating
163 sbpro, I/O sbpro registers too. If we are emulating MSS, the sbpro
164 registers are not used, in no way, to emulate an sbpro: they are
165 used only for configuration purposes.
167 Started Fri Mar 17 16:13:18 MET 1995
169 v0.1 (ALPHA, was an user-level program called AudioExcelDSP16.c)
173 - Integrated with Linux voxware v 2.90-2 kernel sound driver.
174 - SoundBlaster Pro mode configuration.
175 - Microsoft Sound System mode configuration.
176 - MPU-401 mode configuration.
179 - Rearranged the code to let aedsp16_init_board be more general.
180 - Erased the REALLY_SLOW_IO. We don't need it. Erased the linux/io.h
181 inclusion too. We rely on os.h
182 - Used the to get a variable
183 len string (we are not sure about the len of Copyright string).
184 This works with any SB and compatible.
185 - Added the code to request_region at device init (should go in
186 the main body of voxware).
188 - Better configure.c patch for aedsp16 configuration (better
189 logic of inclusion of AEDSP16 support)
190 - Modified the conditional compilation to better support more than
191 one sound card of the emulated type (read the NOTES above)
192 - Moved the sb init routine from the attach to the very first
194 - Rearrangements and cleanups
195 - Wiped out some unnecessary code and variables: this is kernel
196 code so it is better save some TEXT and DATA
197 - Fixed the request_region code. We must allocate the aedsp16 (sbpro)
198 I/O ports in any case because they are used to access the DSP
199 configuration registers and we can not allow anyone to get them.
201 - cleanups on comments
202 - prep for diffs against v3.0-proto-950402
204 - removed the request_region()s when compiling the MODULE sound.o
205 because we are not allowed (by the actual voxware structure) to
207 v0.7 (pre ALPHA, not distributed)
208 - started porting this module to kernel 1.3.84. Dummy probe/attach
211 - attached all the init routines.
213 - Integrated with linux-pre2.0.7
214 - Integrated with configuration scripts.
215 - Cleaned up and beautyfied the code.
217 - Thanks to Piercarlo Grandi: corrected the conditonal compilation code.
218 Now only the code configured is compiled in, with some memory saving.
220 - Integration into the sound/lowlevel/ section of the sound driver.
221 - Re-organized the code.
222 v0.9.11 (not distributed)
223 - Rewritten the init interface-routines to initialize the AEDSP16 in
227 - More soft/hard configuration.
229 - Refined the v0.9.11 code with conditional compilation to distinguish
230 between SC-6000 and SC-6600 code.
232 - Prep for merging with OSS Lite and Linux kernel 2.1.13
233 - Corrected a bug in request/check/release region calls (thanks to the
234 new kernel exception handling).
236 - Revamped for integration with new modularized sound drivers: to enhance
237 the flexibility of modular version, I have removed all the conditional
238 compilation for SBPRO, MPU and MSS code. Now it is all managed with
239 the ae_config structure.
241 - Module informations added.
242 - Removed aedsp16_delay_10msec(), now using mdelay(10)
243 - All data and funcs moved to .*.init section.
245 Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/09/27
246 - got rid of check_region
249 - Audio Excel DSP 16 III don't work with this driver.
252 Many thanks to Gerald Britton <gbritton@CapAccess.org>. He helped me a
253 lot in testing the 0.9.11 and 0.9.12 versions of this driver.
