I'm sure there's an HPET patch floating around, but if I understand things correctly it wouldn't help your system at all, since you are way over the 30+ wakeups per seconds where HPET can do better than the other timers. On the other hand, you have lots of extra timer interrupts. Did you not enable NO_HZ because you are using a 64bit arch ? In this case, a "64bit NO_HZ" patch is much more interesting. Try http://www.tglx.de/projects/hrtimers/ which will give you that (amongst other things) if I'm not mistaken. _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
