Hi,
Is hrtimers supported in the powerpc arch and used in embedded powerpc
drivers? I greped ktime_t and hrtimer_start() under arch/powerpc and
found not two many calls. Does it indicate the powerpc world doesn't
use hrtimers?
Thanks,
-Ryan.

They are there and should work just fine. Why would we "use" them from
arch code ?
Cheers,
Ben.
