+ 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.

++ This cpuidle governor evaluates all available states and chooses the
++ deepest state that meets all of the following constraints: BM activity,
++ expected time until next timer interrupt, and last break event time
++ delta. It is designed to minimize power consumption. Currently
++ dynticks is required.
