anyways, i still see the mysterious pauses which do not show up in the preempt_max_thresh.
ah, and btw: what does the /proc/sys/kernel/kernel_preemption tunable do with PREEMPT_REALTIME enabled?
mango:~# cat /proc/sys/kernel/kernel_preemption 1
[all the other VP tunables are not available anymore]
mango:~# cat /proc/sys/kernel/voluntary_preemption cat: /proc/sys/kernel/voluntary_preemption: No such file or directory mango:~# cat /proc/sys/kernel/hardirq_preemption cat: /proc/sys/kernel/hardirq_preemption: No such file or directory mango:~# cat /proc/sys/kernel/softirq_preemption cat: /proc/sys/kernel/softirq_preemption: No such file or directory
