From df05d846a435268b454eb03fee3b7859dfc94471 Mon Sep 17 00:00:00 2001 From: Morten Rasmussen Date: Tue, 27 Jan 2015 13:48:07 +0000 Subject: sched, cpuidle: Track cpuidle state index in the scheduler The idle-state of each cpu is currently pointed to by rq->idle_state but there isn't any information in the struct cpuidle_state that can used to look up the idle-state energy model data stored in struct sched_group_energy. For this purpose is necessary to store the idle state index as well. Ideally, the idle-state data should be unified. cc: Ingo Molnar cc: Peter Zijlstra Signed-off-by: Morten Rasmussen --- include/linux/cpuidle.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include/linux') diff --git a/include/linux/cpuidle.h b/include/linux/cpuidle.h index 786ad32631a6..6eae1576499e 100644 --- a/include/linux/cpuidle.h +++ b/include/linux/cpuidle.h @@ -204,7 +204,7 @@ static inline int cpuidle_enter_freeze(struct cpuidle_driver *drv, #endif /* kernel/sched/idle.c */ -extern void sched_idle_set_state(struct cpuidle_state *idle_state); +extern void sched_idle_set_state(struct cpuidle_state *idle_state, int index); extern void default_idle_call(void); #ifdef CONFIG_ARCH_NEEDS_CPU_IDLE_COUPLED -- cgit v1.2.3
