- 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.

- Allows the cpuidle framework to use different drivers for each CPU.
- This is useful if you have a system with different CPU latencies and
- states. If unsure say N.
