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.
