- Supporting multiple CPU idle levels in kernel
- cpuidle governors
- cpuidle governor is policy routine that decides what idle state to enter at
- any given time. cpuidle core uses different callbacks to the governor.
- * enable() to enable governor for a particular device
- * disable() to disable governor for a particular device
- * select() to select an idle state to enter
- * reflect() called after returning from the idle state, which can be used
- by the governor for some record keeping.
- More than one governor can be registered at the same time and
- users can switch between drivers using /sysfs interface (when enabled).
- More than one governor part is supported for developers to easily experiment
- with different governors. By default, most optimal governor based on your
- kernel configuration and platform will be selected by cpuidle.
- Interfaces:
- extern int cpuidle_register_governor(struct cpuidle_governor *gov);
- struct cpuidle_governor
