GUSPNP15 8/6//97
ftp://rah.star-gate.com/pub/guspnp.tar.gz
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 .

http://www.iet.unipi.it/~luigi/pnp.c
http://www.iet.unipi.it/~luigi/pnp.h
the two main files. Follow Sujal Patel's instructions
for installing pnp support.
http://www.iet.unipi.it/~luigi/pnpinfo.tgz
---
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,
Amancio
