I agree a numerical value is not flexible. But it sounds weird to put a scheduler option in the sysfs and maybe more options will follow.
I am wondering if we shouldn't create a new cgroup for 'energy' and put everything in there. So we will have more flexibility for extension and we will be able to create a group of tasks for performance and a group of tasks for energy saving.
Does it make sense ?
The old knobs used to live here:
-What: /sys/devices/system/cpu/sched_mc_power_savings - /sys/devices/system/cpu/sched_smt_power_savings
Not entirely sure that's a fine place, but it has precedent.
