Re: Yamaha OPL-SA2 newpcm: recognized but no sound

It used to work under VoxWare as css device friends, but does not want to anymore either :-( I added some code to the mss driver to implement more mixer functionality for the yamaha but I wasn't able to test it properly since the sound hardware on my laptop seems to be wired up a bit differently from 'normal' opl3-sa2 cards.

ps doesn't need privileges?
Please don't flame me if I'm asking something stupid, but I'm a bit confused. I always thought that /bin/ps needs to be setgid kmem to be able to display the process list. And this in fact seems to be the fact under 2.2.8: /home/blaz uname -a FreeBSD server.amis.net 2.2.8-RELEASE FreeBSD 2.2.8-RELEASE #0: Mon Dec 14 19:22:23 CET 1998 [EMAIL PROTECTED]:/usr/src/sys/compile/SERVER i386 /home/blaz ls -la /bin/ps -r-xr-sr-x 1 bin kmem 176128 Oct 26 1998 /bin/ps /home/blaz cp /bin/ps /tmp /home/blaz ls -la /tmp/ps -r-xr-xr-x 1 blaz bin 176128 Sep 11 14:08 /tmp/ps /home/blaz /tmp/ps ax ps: /dev/mem: Permission denied As expected, a copy of ps without setgid kmem can't display the process list.

Re: optional 'make release' speed-up patch
YES please fix this ridiculous inefficiency pointed out by Rod!
The current method of cleaning the build tree is to chflags -R and
then rm -r which results in two full traversals of the entire /usr/obj
tree which takes MUCH longer than attempting an rm -r first followed by
a chflags -R and another rm -r.
Rather than patch /usr/src/Makefile.inc1, I have been using an alias
for the last year or so:
mkworld (rm -rf /usr/obj/usr ; chflags -R noschg /usr/obj/usr ; rm -rf
/usr/obj/usr ; cd /usr/src make world) /usr/src/WORLD.log.`date
"+%g%m%d"`
Also while I was looking at /usr/src/Makefile I noticed the following
paragraph. Is this still true (the defaulting to a.out) ? There is also
is a typo: "or 3.0." should be "of 3.0.".
# The `make world' process always follows the installed object format.
# This is set by creating /etc/objformat containing either OBJFORMAT=aout
# or OBJFORMAT=elf. If this file does not exist, the object format defaults
# to aout. This is expected to be changed to elf just prior to the release
# or 3.0. If OBJFORMAT is set as an environment variable or in /etc/make.conf,
# this overrides /etc/objformat.

Hi,
The following patch to /usr/src/release/Makefile allows the
specification of the variable FASTCLEAN, which instead of doing
a recursive rm on CHROOTDIR, simply umounts/newfs/mounts. Of
course, this is only useful if your CHROOTDIR location is a
separate mount point (which mine is: /snap).
Comments and critiques welcome.
And how about a similiar patch to /usr/src/Makefile that is
FASTCLEANDIR that brings back a patched up version of
my original CLEANDIR. Something like
-rm -rf /usr/obj/${.CURDIR}/tmp
chflags -R noschg /usr/obj/${.CURDIR}/tmp
rm -rf /usr/obj/${.CURDIR}
Would someone consider committing this please?
Thanks,

Re: NewPCM and Quake :)
I am having a few problems with newpcm. I often play a whole bunch of Sesame Street AVIs to keep the 1 and 3 year olds happy while I read email. I usually play them like so (straight from the CD-ROM): foreach blah ( /cdrom/letters/tv/*.avi ) xanim -Zr +Ze +Av`mixer | grep pcm | cut -d: -f2` $blah /dev/null end This worked fine with the old sound drivers but now I find that I have to put in a 1 second sleep after xanim or the sound will usually stop completely after the first AVI. I am also now getting the following messages on the console: "dsp sync" I get 4 of these at the start of each invocation of xanim and then I get 1 at the end of each invocation of xanim. When the sound has stopped completely I have to reboot to get it back. My -CURRENT is about 3 days old.
