File intel_pstate.patch of Package pm-profiler
intel_pstate driver has only "powersave" and "performance" governors. intel_pstate "powersave" acts the same way as "ondemand" for the other drivers. Adjust code to set governor to "powersave" when anything other than "performance" is requested. --- pm-profiler-0.1_20111222/tools/enable-profile.orig 2011-12-22 08:36:52.000000000 +0100 +++ pm-profiler-0.1_20111222/tools/enable-profile 2015-09-24 12:47:58.501765806 +0200 @@ -33,8 +33,14 @@ if [ "$?" != "0" ]; then fi function cpufreq_governor { - for I in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do - echo $CPUFREQ_GOVERNOR > $I + for I in /sys/devices/system/cpu/cpu[[:digit:]]*/cpufreq; do + Driver=`cat $I/scaling_driver` + # intel_pstate has no ondemand governor, powersave handles this just fine + if [ "$Driver" = "intel_pstate" -a "$CPUFREQ_GOVERNOR" != "performance" ]; then + echo powersave > $I/scaling_governor + else + echo $CPUFREQ_GOVERNOR > $I/scaling_governor + fi done } @@ -111,5 +117,3 @@ echo $PROFILE > $STATEFILE exit 0 - -#sed -e "s/CURRENT_PROFILE=\".*\"/CURRENT_PROFILE=\"$PROFILE\"/g" -i /etc/pm-profiler.conf
