+Description: Discover cpuidle policy and mechanism
+
+ Various CPUs today support multiple idle levels that are
+ differentiated by varying exit latencies and power
+ consumption during idle.
+
+ Idle policy (governor) is differentiated from idle mechanism
+ (driver)
+
+ current_driver: displays current idle mechanism
+
+ current_governor_ro: displays current idle policy
+
+ See files in Documentation/cpuidle/ for more information.
