CPU idle is a generic framework for supporting software-controlled
idle processor power management. It includes modular cross-platform
governors that can be swapped during runtime.
- If you're using an ACPI-enabled platform, you should say Y here.
+ If you're using a mobile platform that supports CPU idle PM (e.g.
+ an ACPI-capable notebook), you should say Y here.

+ This cpuidle governor evaluates all available states and chooses the
