108Description: Discover cpuidle policy and mechanism
109
110 Various CPUs today support multiple idle levels that are
111 differentiated by varying exit latencies and power
112 consumption during idle.
113
114 Idle policy (governor) is differentiated from idle mechanism
115 (driver)
116
117 current_driver: displays current idle mechanism
118
119 current_governor_ro: displays current idle policy
120
121 See files in Documentation/cpuidle/ for more information.
