This function must be called between cpuidle_pause_and_lock and cpuidle_resume_and_unlock when used externally.

Definition at line 369 of file cpuidle.c.

int cpuidle_disabled ( void )

Definition at line 34 of file cpuidle.c.

int cpuidle_enable_device ( struct cpuidle_device * dev )

cpuidle_enable_device - enables idle PM for a CPU : the CPU

This function must be called between cpuidle_pause_and_lock and cpuidle_resume_and_unlock when used externally.

Definition at line 308 of file cpuidle.c.

int cpuidle_enter_state	(	struct cpuidle_device *	dev,
		struct cpuidle_driver *	drv,
