I currently have a PAS-16 card configured in my kernel. To properly
configure the card I need the following stuff in my configuration file:
---
options ALLOW_CONFLICT_IOADDR # For pas0 & opl0
#options "PAS_SYMPHONY" # Only use if symphony chip set probs
options BROKEN_BUS_CLOCK # Only use if OPTI chip set probs
options EXCLUDE_SBPRO # PAS has old SB emulation
options "SBC_IRQ=5" # SBC_IRQ must match irq on sb0 line
# sound stuff... Order is important here, the pas device must be configured
# before the sb device, since the sb emulation gets set in the pas attach.
controller snd0
device pas0 at isa? port 0x388 irq 12 drq 3 vector pasintr
device sb0 at isa? port 0x220 irq 5 drq 1 vector sbintr
device opl0 at isa? port 0x388
---
Using this configuration, I am able to read and write to /dev/{dsp,audio},
and write /dev/{dsp,audio}1, and use the pas-16 card as a full duplex audio
card. Other than the standard flakiness of the pas card this configuration
works well.
I also have a GUS-16 card (rev 3.7) and a couple of GUSMAX cards. I am not
certain what the correct configuration of these cards are. The GUSMAX
card seems to have a SB dma, and two gus dma channels (one for read and one
for write) as well as two interrupts (one for sb and one for gus).
Looking at the possible configurations I don't see how to take advantage
of this. I have tried this configuration.
---
device gus0 at isa? port 0x220 irq 12 drq 7 vector gusintr
device gusxvi0 at isa? port 0x530 irq 12 drq 7 vector adintr
device gusmax0 at isa? port 0x32c
device sb0 at isa? port 0x220 irq 5 drq 1 vector sbintr
device opl0 at isa? port 0x388
---
The kernel comes back with:
gus0: at 0x220 irq 12 drq 7 on isa
gus0: <Gravis UltraSound MAX (512k)>
gusxvi0: not probed due to conflict with gus0 at 7
gusmax0 not found at 0x32c
sb0 not found at 0x220
opl0 at 0x388 on isa
opl0: <Yamaha 2-OP FM>
When I try and read/write /dev/{dsp,audio} I get an error; however,
/dev/{dsp,audio}1 seem to work (somewhat).
Questions:
Has the old full duplex code been brought forward into the new sound
drivers for the gus card? If not, is someone already doing this or should
I take a hack at it?
What is the correct configuration for a gus-16 card?
What is the correct configuration for a gus-max card?
Anyone know why the sb emulation doesn't work with the gus cards?
Thanks for any help,
-Jim
