  8. CPU idle is a generic framework for supporting software-controlled
  9. idle processor power management. It includes modular cross-platform
  10. governors that can be swapped during runtime.
  11. If you're using an ACPI-enabled platform, you should say Y here.

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