Re: hpet timer patch for powertop

["Ahmed Kamal" <email.ahmedkamal@xxxxxxxxxxxxxx>]

Cool, but it seems that my tickless kernel is ticking! Also since "grep -i hpet /proc/timer_list" returns nothing, it seems my BIOS is disabling hpet, so the hpet force-enable patch is needed. I guess the question now is, will F8 kernel contain that patch? Since the powertop guys say that *lots* of BIOSs disable hpet, I think it's beneficial to merge that.

actually I'm still on FC6, and I'm using i686 CPU. The kernel is from tuxonice (suspend2) which is basically the same fedora kernel with suspend2 patches. Anyway, I thought all .22 kernels had tickless, dont they.
If all of this + hpet patches will be in fedora8, I will be a happy fedorian ;)

Yes, all kernels >= 2.6.22 for x86 are tickless. x86_64 are not for f7 but will be for f8.
