Hello,
My sysfs is missing sched_mc_power_savings entry, so this gives me an error:
echo 1 > /sys/devices/system/cpu/sched_mc_power_savings
zsh: no such file or directory: /sys/devices/system/cpu/sched_mc_power_savings
I tested it on kernel26-2.6.39.1-1 from [core], kernel26-ice from AUR with some modifications:
