| Thread-topic: | [PATCH 4/4] CPUIDLE: Port menu governor |
CPUIDLE: Port Linux menu governor to replace the initial ladder governor The ladder governor has long pro/demotion delay shortcome while applying to tickless mode, because it needs to count usage. Menu governor chooses the next state simply via break-event prediction including the factors of next timer event & last residency time etc, so it would have faster response speed. Signed-off-by: Gang Wei <gang.wei@xxxxxxxxx>
