I'm running Debian Wheezy, with a 32 bit 3.6.6 kernel including the HPET quirks patch. I looked into these settings, and found the following: pcie_aspm=off -- not needed; ASPM seems to be disabled for this chipset already. processor.max_cstate=1 -- not used; one can get a similar effect with "intel_idle.max_cstate=1". clocksource=tsc -- not needed. If "intel_idle.max_cstate" is set to 1, then TSC will be automatically selected as the clock source. Otherwise, HPET will be used (since the kernel was compiled with the HPET quirks patch). So my question, to anyone who knows, is whether it is better to use HPET as the clocksource, or to set "intel_idle.max_cstate=1" and use TSC? Or is there no noticeable difference? /Lon Willett _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
