Thanks, so DTPM can be a good solution for ARM. We could also deal
with AMD with acpi-cpufreq if powercap is not supported yet.

That aside, I think cpu cgroup has a familiar and simple sysfs
interface, and is more importantly hardware agnostic so it would be
really nice to have.

Alternatively, I assume we can look into a device-independent idle
injection mechanism?
