Hi,
 what exactly is the effect of enabling "power save mode" on multi-core
aware CPU scheduler?
( echo 1 > /sys/devices/system/cpu/sched_mc_power_savings )

As far as I understood from [1], it only affects systems with more
than one multi-core physical CPU. Does it have any effect on a system
with one dual-core CPU?

Thanks,
 MM
