| Supporting multiple CPU idle levels in kernel
|Various CPUs today support multiple idle levels that are differentiated
|by varying exit latencies and power consumption during idle.
|cpuidle is a generic in-kernel infrastructure that separates
|idle policy (governor) from idle mechanism (driver) and provides a
|standardized infrastructure to support independent development of
|governors and drivers.
|cpuidle resides under drivers/cpuidle.
|enables current_governor interface in /sys/devices/system/cpu/cpuidle/,
|which can be used to switch governors at run time. This boot option
|is meant for developer testing only. In normal usage, kernel picks the
|best governor based on governor ratings.
