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).
Thanks for forwarding the link, Lee. That's helpful information.
Thomas, does this dynamic priority support work when running softirq-timer/0
at SCHED_OTHER? I tried, and it seems to work here, I just want to make sure
it's valid to do so.
