This is only true, when high resolution timers are enabled.
Is there any solution for the !CONFIG_HIGH_RES_TIMERS case? I for one
can't use it because my hardware doesn't support it (no local APIC).
What hardware platform ?
Via C3 mini ITX board.
HRT works with PIT only too.
I was not aware of that.
Otherwise you really need to chrt the
hrtimers softirq prio statically.
The problem was that setting the thread's priority to 99 caused long
latencies every 10 minutes when rt_secret_rebuild() ran, as if the timer
callbacks that do real work and the ones that just deliver a signal are
all running from the softirq timer thread.
