I recently switched to a patched version PAM able to use rt_priority in
I launched jack and got a warning that it was unable to set priority
(this value was X+10 with -P X).
I looked at the code and I found that a whatchdog thread is started
like that but if it failed to set the priority this thread has normal prio
and jack doesn't failed isn't it dangerous?
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
5272 moino 19 0 22604 22m 4820 S 0 2.2 0:00.01 jackd
5273 moino 18 0 22604 22m 4820 S 0 2.2 0:00.00 jackd
5274 moino 16 0 22604 22m 4820 S 0 2.2 0:00.00 jackd
5275 moino 16 0 22604 22m 4820 S 0 2.2 0:00.00 jackd
5276 moino -71 0 22604 22m 4820 S 0 2.2 0:00.98 jackd
this was done with rt_priority set to 70 in limits.conf and jackd
started like this : jackd -R -P 70 -d alsa.
LD_ASSUME_KERNEL=2.4.19 does not work anymore on my
system. How can I check if I'm affected by the bug with
SCHED_FIFO threads? It seems to work...
Sorry for posting to this mailing but I cannot subscribe to jack mailing.
