Announcing the pcmaudio(4) driver, for all geeks with lots of PWM,
lots of time, lots of boredome and nothing else to do.
Its basically been an exercise in writing a device driver for NetBSD,
and has only been tested with mplayer and xine.
plaympeg (libSDL) doesn't seem to work for some reason.
PWM translation seems to have some sort of bug, when the volume
sound gets scratchy. I'm sure I'm missing something obvious in
I've tried to organise the code to be as little intrusive as
however, it does touch x86/isa/clock.c, pcppi(4) and attimer(4), so
here's what I'm asking anyone with the inclination to try:
Could you run it on a slower machine (i386/486 etc) and see if it
works at all ? Also, if you disabled it, does it affect anything else
I don't expect to commit this anytime soon, unless someone absolutely
needs this in the tree :-)
If it a) works b) doesn't break anything c) could be remotely useful
for someone, why not develop it in the tree?
Yeah, I'm sure it will have more users than some of my drivers ;)
( Fujitsu AG-10e anyone? )
