hi ! I have now run 2.6.23-rc4-rt1 on my arm920t with the pi_stress test programm from http://people.redhat.com/williams/tests My question if I run the pi_stress, my watchdog triggers, if watchdog is disabled i get this: Admin threads running on processor: 0 Test threads running on processor: 0 Starting PI Stress Test Number of thread groups: 10 Number of inversions per group: infinite Test threads using scheduler policy: SCHED_FIFO Admin thread priority: 4 10 groups of 3 threads will be created High thread priority: 3 Med thread priority: 2 Low thread priority: 1 Press Control-C to stop test Current Inversions: 15551 Keyboard Interrupt! Stopping test Total inversion performed: 15570 Test Duration: 0 days, 0 hours, 0 minutes, 14 seconds Is this the correct behaviour ? Or does it show a problem ? thanks, regards fred Am Tuesday 21 August 2007 schrieben Sie: > Hi Remy ! > > thanks a lot, i will test it on a ARM-v4 with 2.6.23-rc2-rt2 and > 2.6.21.5-rt20. > > I have a application which makes a lot of pthread_mutex_lock/unlock > between rt and non-rt tasks with PI.
