Subject: Problems with cyclictest and ps
Date: Wed, 05 Dec 2007 21:34:24 +0100	[thread overview]
Message-ID: <47570B50.9060502@gmail.com> (raw)

Hi,

I tried cyclictest under Debian Lenny with Kernel-2.6.23.8-hrt3 and
Kernel-2.6.22 as user root. As decribed on the cyclictest-wikipage all
cyclictest-tasks run with the scheduler class SCHED_FIFO. I controlled
the scheduler class with "ps -ce" and ps showed me SCHED_OTHER for the
cyclictest-task.

#> ./cyclictest -t 1 -p 80 -n -i 10000

#> ps -ce | grep cyclic
   PID CLS PRI TTY          TIME CMD
  9693 TS   19 pts/5    00:00:00 cyclictest

I am wondering why cyclictest runs as SCHED_OTHER I expected SCHED_FIFO
instead. Any explanations of this behavior are welcome.

Regards,

Phil
