This sound driver is for FreeBSD 3.0-current .
|
||
|
|
|
||
|
|
|
||
|
|
Major enhancement we now support mapping the dma buffer to user
|
||
|
|
space for write operations only. This features is useful for
|
||
|
|
games like xquake . So far the mmap features seems to work
|
||
|
|
with the GUS PnP Pro and with the SB16.
|
||
|
|
|
||
|
|
For xquake you will need:
|
||
|
|
|
||
|
|
1. a few mods to the linux loadable module so just download it and
|
||
|
|
replace yours:
|
||
|
|
cd /sys/i386/
|
||
|
|
tar -xzf linux_ioctl.tar.gz
|
||
|
|
cd /usr/src/lkm/linux
|
||
|
|
make
|
||
|
|
make install
|
||
|
|
modunload -i 0 (if you have the linux up and running)
|
||
|
|
linux
|
||
|
|
ftp://rah.star-gate.com/linux_ioctl.tar.gz
|
||
|
|
|
||
|
|
2. Install the linux lib 2.4 package:
|
||
|
|
pkg_add linux_lib-2.4.tgz
|
||
|
|
|
||
|
|
ftp://ftp.freebsd.org/pub/FreeBSD/packages-current/emulators/linux_lib-2.4.tgz
|
||
|
|
|
||
|
|
If you don't have xquake you can get it from:
|
||
|
|
|
||
|
|
3. ftp://ftp.freebsd.org/pub/idgames/idstuff/unsup/intel_linux_quake101.tgz
|
||
|
|
|
||
|
|
|
||
|
|
A simple test program mmap_test.c is provided in the sound driver directory.
|
||
|
|
So copy it to your home directory or favorite place and compile it.
|
||
|
|
cc -o mmap_test mmap_test.c
|
||
|
|
|
||
|
|
record a sample session:
|
||
|
|
cat /dev/dsp >smpl
|
||
|
|
|
||
|
|
now run mmap_test . You will hear a loud pop thats a test program
|
||
|
|
then the sample stream will loop .
|
||
|
|
|
||
|
|
|
||
|
|
Phew, now back to sound driver land 8)
|
||
|
|
|
||
|
|
|
||
|
|
This is a minor sound driver release for the GUS PnP Pro , GUS MAX,
|
||
|
|
AudioTrix Pro , SB16 and SB16 PnP. There is also an experimental
|
||
|
|
AWE sub model.
|
||
|
|
|
||
|
|
Included Luigi's clean up work . Tnks!
|
||
|
|
|
||
|
|
Randall Hopper's SB16 speed setting fix . Tnks!
|
||
|
|
|
||
|
|
Fixed signal handling throught out the sound driver. The problem
|
||
|
|
first surfaced with the SB16 not generating an interrupt on the
|
||
|
|
last dma request and SB afficionados quickly pointed out the
|
||
|
|
bug in the driver. I had to put back the auto dma feature for
|
||
|
|
xquake :(
|
||
|
|
|
||
|
|
|
||
|
|
NOTE YOU DON'T NEED THE PNP DRIVER FOR THE GUS PNP SINCE THE DRIVER
|
||
|
|
HAS BUILTIN PNP SUPPORT FOR THE GUS.
|
||
|
|
|
||
|
|
My P133 Bios supports PnP. To first figured out what my SB16 PnP
|
||
|
|
was being configured to I booted win95 and checked out what Win95
|
||
|
|
ended up with . Alternatively, if you want to you can also down
|
||
|
|
load Sujal Patel's PnP driver:
|
||
|
|
|
||
|
|
ftp://rah.start-gate.com/pub/FreeBSD-ISA_PnP_June8.tar.gz
|
||
|
|
|
||
|
|
follow the instructions on how to configure your PnP soundcard or
|
||
|
|
ISA device.
|
||
|
|
Lugi also has Sujal's PnP driver .

This is my kernel configuration for my SB16 PnP:
|
||
|
|
|
||
|
|
controller snd0
|
||
|
|
device sb0 at isa? port 0x220 irq 10 conflicts drq 3
|
||
|
|
device sbxvi0 at isa? port? irq? drq 5 conflicts
|
||
|
|
device opl0 at isa? port 0x388 conflicts
|
||
|
|
device sbmidi0 at isa? port 0x300 irq? conflicts
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
|
||
|
|
The difference between a GUS PnP and a GUS PnP PRO is that the Pro
|
||
|
|
comes with 512kb. I went out an got a 1mb 60ns 30pin simm and installed
|
||
|
|
it on my GUS PnP. I own a GUS PnP and a GUS PnP PRO.
|

To unpack:
|
||
|
|
cd /
|
||
|
|
mv /sys/i386/isa/sound /sys/i386/isa/sound.old
|
||
|
|
cd /sys/i386/isa/
|
||
|
|
tar -xzf guspnp15.tar.gz
|
||
|
|
|
||
|
|
|
||
|
|
cd /sys/i386/conf
|
||
|
|
Edit the kernel config file in /sys/i386/conf
|
||
|
|
|
||
|
|
IF YOU HAVE A GUS MAX or GUS add the option NOGUSPNP to the config file
|
||
|
|
OPTIONS NOGUSPNP
|
||
|
|
THEN follow the instructions for NONPNP CONFIGURATION
|
||
|
|
|
||
|
|
|
||
|
|
PNP CONFIGURATION
|
||
|
|
To configure your guspnp PRO if you have a motherboard which supports
|
||
|
|
PnP:
|
||
|
|
|
||
|
|
controller snd0
|
||
|
|
device gus0 at isa?
|
||
|
|
|
||
|
|
NONPNP CONFIGURATION
|
||
|
|
To configure your guspnp PRO if your motherboard does NOT support
|
||
|
|
PnP:
|
||
|
|
|
||
|
|
device gus0 at isa? port 0x220 irq 11 drq 1 flags 0x3
|
||
|
|
|
||
|
|
|
||
|
|
the gus pnp is fully software configurable and the above configuration
|
||
|
|
is setup for full duplex audio. The dma channel settings are:
|
||
|
|
|
||
|
|
drq 1 --- DMA channel for playback
|
||
|
|
|
||
|
|
flags 0x3 --- DMAN channel for recording
|
||
|
|
|
||
|
|
In the event that you have to configure a GUS PnP manually or a GUS MAX:
|
||
|
|
|
||
|
|
Available IRQs for the GUS are:
|
||
|
|
3, 5, 7, 9, 11, 12, 15
|
||
|
|
|
||
|
|
Available DMA channels for the GUS are:
|
||
|
|
1, 3, 5, 6, 7
|
||
|
|
|
||
|
|
|
||
|
|
config <kernel-file>
|
||
|
|
cd /sys/compile/<kernel-file>
|
||
|
|
make
|
||
|
|
make install
|
||
|
|
|
||
|
|
THERE IS NO NEED TO BOOT TO DOS TO CONFIGURE YOUR GUS PNP.
|
||
|
|
THE DRIVER HAS BUILTIN SUPPORT FOR PNP WHICH I GOT
|
||
|
|
FROM THE GRAVIS DRIVER DEVELOPMENT KIT

Many thanks to Brian Litzinger <brian@MediaCity.com> for
|
||
|
|
porting the sound driver 3.5 to 2.2-current. Well, thats a while
|
||
|
|
ago hence the reference to 2.2.
|
||
|
|
|
||
|
|
Have fun,
