cpuidle_unregister_governor() and cpuidle_replace_governor() aren't used anymore and can be removed. They were used by cpufreq governors earlier, but since the governors can't be compiled as modules any more, these two functions aren't necessary.

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
