From /sys/devices/system/cpu/cpuN/cpufreq/scaling_driver I get that the current p-state driver is called "intel_pstate". David, you mention that the firmware governors are not very efficient, do you suggest replacing the intel_pstate driver with a different driver?
I will need to look and see why changing to performance isn't working correctly. To get the behavior of the performance governor you can use echo 100 > /sys/devices/system/cpu/intel_pstate/min_perf_pct This will force intel_pstate to select the highest P state and leave it there. Turbostat is useful for collecting frequency (P state) and idle (C state) information. --Dirk -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
