Open Sound System

Sometimes system crashes with kernel panic when OSS is used.
Sometimes system just hangs and system is stalled when OSS is used.

Sometimes I am able to see this, but then I can't get mplayer process killed in any way (kill -9 doesn't work):

When using snd_hda FreeBSD module system is very stable, so I think it's OSS problem.

From my testing I can see that OSS build 1008 is much more stable than newer versions.

Any suggestions would be great... Thank you!

You're not the first to report this. There are several things you can try:
A. Does the version from the mercurial repository work? See here for how to build it.
B. If you can pinpoint where the regression exactly took place, it would be really helpful. I've made tarballs of the source of previous versions available. If you can test these, we may find out where the regression took place. Note that freebsd ports includes patches, which you may wish to apply to the source. (Most of these patches have been also applied to mercurial tip, except for the GETBLKSIZE one, which you may want to apply there too).

You can also try commenting out USE_SX_LOCK, though that didn't work in the previous thread.

by **muanton** » Thu Jul 24, 2008 1:45 pm

Version from mercurial repository do not work too. Just tested it.

I've found easier way to reproduce *oss STATE hang - ossmix hangs when launched a few times without any parameters (when adjusting sound levels - it doesn't hang). Maybe this could help debugging and finding the problem...

I'm using OSS on more than 20 computers which are used to display video ads on TV screens. As far as I remember the last stable version was b1008. Had stability problems with b1012.

I'm going to test b1011 in a few hours...

by **cesium** » Thu Jul 24, 2008 2:30 pm

I diffed versions 1008, 1011 and 1012. It turns out there are no BSD-specific difference I could find between 1008 and 1011. There were quite a few between 1011 and 1012. I noticed you're using FreeBSD v6, so assuming the check

Code: Select all: #if __FreeBSD_version >= 700031 #define USE_SX_LOCK 1 #endif

is correct, I removed all diffs regarding the SX lock. All that's left is at http://oss.pastebin.com/m53484b99 . Another option, is that FreeBSD's ports had a patch for 1008 build which was removed, which happened to fix the issue. I found a candidate at: http://www.freebsd.org/cgi/cvsweb.cgi/p ... ideattic=0 . I suspect either of these two diffs contains the solution somewhere. Can you see any error? Does applying the msleep_spin diff help?

by **muanton** » Thu Jul 24, 2008 3:16 pm

I was trying to install (make install) b1011 and got his error:

Code: Select all: Compiling module oss_ali5455 Compiling module oss_ali5455 failed Warning: Object directory not changed from original /usr/lib/oss/build @ -> /usr/src/sys machine -> /usr/src/sys/i386/include awk -f @/tools/makeobjops.awk @/kern/device_if.m -h awk -f @/tools/makeobjops.awk @/kern/bus_if.m -h awk -f @/tools/makeobjops.awk @/dev/pci/pci_if.m -h make: don't know how to make oss_ali5455.c. Stop *** Error code 2 Stop in /usr/home/muanton/oss.

Any workaround?

msleep_spin diff/change didn't help with the version from mercurial repository.

by **cesium** » Thu Jul 24, 2008 3:24 pm

I think the files got mixed up somehow.. The mercurial/4.1 version uses "oss_*" driver names, while 4.0 didn't have a prefix. The 4.1 files remained, and make is trying to compile these too... To try b1011, remove the previous /usr/lib/oss/build and do "make install" again.

Another thing we can try, is to undo part of the os_freebsd.h 1011->1012 diff in the mercurial version, by restoring the old definitions to the !USE_SX_LOCK #else. i.e.

Code: Select all: #else /* !USE_SX_LOCK */ struct mtx; #define MUTEX_INIT(osdev, mutex, hier) \ { \ mutex = malloc(sizeof (*mutex), M_DEVBUF, M_NOWAIT|M_ZERO); \ mtx_init(mutex, "oss", NULL, MTX_RECURSE|MTX_SPIN); \ } #define MUTEX_CLEANUP(mutex) { mtx_destroy (mutex); free(mutex, M_DEVBUF); } #define MUTEX_ENTER_IRQDISABLE(mutex, flags) mtx_lock_spin_flags(mutex, flags) #define MUTEX_ENTER(mutex, flags) mtx_lock_spin(mutex) #define MUTEX_EXIT_IRQRESTORE(mutex, flags) mtx_unlock_spin_flags(mutex, flags) #define MUTEX_EXIT(mutex, flags) mtx_unlock_spin (mutex) #endif

instead of the previous #else part in os_freebsd.h (recompile neccesary in that case).

by **muanton** » Thu Jul 24, 2008 3:48 pm

Tried removing build directory - I was getting other errors before removing it. It didn't help anyway...

I was comparing os_freebsd.h from b1008 with dev version and decided to replace

Code: Select all: struct mtx; #define MUTEX_INIT(osdev, mutex, hier) \ do { \ mutex = malloc(sizeof(*mutex), M_DEVBUF, M_WAITOK | M_ZERO); \ mtx_init(mutex, "oss", NULL, MTX_RECURSE); \ } while (0) #define MUTEX_CLEANUP(mutex) \ do { \ mtx_destroy(mutex); \ free(mutex, M_DEVBUF); \ } while (0) #define MUTEX_ENTER_IRQDISABLE(mutex, flags) mtx_lock(mutex) #define MUTEX_ENTER(mutex, flags) mtx_lock(mutex) #define MUTEX_EXIT_IRQRESTORE(mutex, flags) mtx_unlock(mutex) #define MUTEX_EXIT(mutex, flags) mtx_unlock(mutex)

with this one (as you suggested):

Code: Select all: struct mtx; #define MUTEX_INIT(osdev, mutex, hier) \ { \ mutex = malloc(sizeof (*mutex), M_DEVBUF, M_NOWAIT|M_ZERO); \ mtx_init(mutex, "oss", NULL, MTX_RECURSE|MTX_SPIN); \ } #define MUTEX_CLEANUP(mutex) { mtx_destroy (mutex); free(mutex, M_DEVBUF); } #define MUTEX_ENTER_IRQDISABLE(mutex, flags) mtx_lock_spin_flags(mutex, flags) #define MUTEX_ENTER(mutex, flags) mtx_lock_spin(mutex) #define MUTEX_EXIT_IRQRESTORE(mutex, flags) mtx_unlock_spin_flags(mutex, flags) #define MUTEX_EXIT(mutex, flags) mtx_unlock_spin (mutex)

ossmix doesn't hang with *oss lock anymore... Started tests with mplayer... Let's see if it hangs..

by **muanton** » Thu Jul 24, 2008 4:27 pm

btw, I've stated in my first post that " OSS build 1008 is much more stable than newer versions"... We are running OSS b1008 on 20 computers, 5 of them hangs randomly while mplayer is playing video. It happens 2-4 times a month. But I think it's motherboard or OS issue, not OSS. But everything was ok while we were using winxp...

by **cesium** » Thu Jul 24, 2008 4:32 pm

You didn't state if mplayer works now. Assuming that it does, and we are somewhere near the cause, I'd like you to test this change: (To previous block)

Code: Select all: #define MUTEX_INIT(osdev, mutex, hier) \ do { \ mutex = malloc(sizeof (*mutex), M_DEVBUF, M_WAITOK|M_ZERO); \ mtx_init(mutex, "oss", NULL, MTX_RECURSE|MTX_SPIN); \ } while (0) #define MUTEX_CLEANUP(mutex) \ do { \ mtx_destroy (mutex); \ free(mutex, M_DEVBUF); \ } while (0) #define MUTEX_ENTER_IRQDISABLE(mutex, flags) mtx_lock_spin_flags(mutex, flags) #define MUTEX_ENTER(mutex, flags) mtx_lock_spin(mutex) #define MUTEX_EXIT_IRQRESTORE(mutex, flags) mtx_unlock_spin_flags(mutex, flags) #define MUTEX_EXIT(mutex, flags) mtx_unlock_spin (mutex) #endif

And in os_freebsd.c replace

Code: Select all: flag = msleep (wq, *mutex, PRIBIO | PCATCH, "oss", ticks);

with:

Code: Select all: flag = mtx_sleep (wq, *mutex, PRIBIO | PCATCH, "oss", ticks);

re: other crashes... I don't know. There could be quite a few possibilities regardless of OSS. Is there anything in common between these computers?

by **muanton** » Thu Jul 24, 2008 5:49 pm

there no more crashes/hangs with mplayer

After changing msleep to mtx_sleep:

Code: Select all: link_elf: symbol mtx_sleep undefined kldload: can't load /usr/lib/oss/modules/osscore.ko: No such file or directory Loading the osscore module failed

I've changed os_freebsd.h as you asked, but in os_freebsd.c I've left this one:

Code: Select all: flag = msleep_spin (wq, *mutex, "oss", ticks);

This one is from FreeBSD port patch. I was using it all the time during my last tests...

With this modification ossmix doesn't hang. mplayer seems to work fine too.. I'm going to leave it playing through the night. Will post results tomorrow.

Does this also affect FreeBSD 7?. I thought freebsd7 was stable now.

by **cesium** » Thu Jul 24, 2008 9:43 pm

There's a thread with a very similar issue on FreeBSD 7.0-STABLE and there's another post with a panic on 8.0-CURRENT (See also report).

by **muanton** » Fri Jul 25, 2008 9:48 am

mplayer was looping video all the night. Everything works fine and no hangs

I have one FreeBSD 7 machine which I can use it for testing OSS.

OK, kindly provide a patch to Hannu (hannu@opensound.com) so that he can include it in the HG version.
