Hello everyone,

I feel a little bit stupid and surprised but supposedly I should have sched_mc_power_savings files in my /sys since I have CONFIG_SCHED_MC defined in my .config and I have a four cores CPU (to be exact Intel Core i5 2500).

Alas, under Linux kernel 3.0-rc5 I don't have the aforementioned files.

Is something wrong going on here?

Best wishes,

Artem

No, it's normal, and appears only when you have multiple CPU packages.
