Name:Recomputes cpu_base::*next_timer and returns the earliest expires_next but* does not set cpu_base::*expires_next, that is done by hrtimer_reprogram
Proto:static ktime_t __hrtimer_get_next_event(struct hrtimer_cpu_base *cpu_base, unsigned int active_mask)
Type:ktime_t
Parameter:
Type | Parameter | Name |
---|---|---|
struct hrtimer_cpu_base * | cpu_base | |
unsigned int | active_mask |
570 | struct hrtimer * next_timer = NULL |
571 | expires_next = KTIME_MAX |
573 | If Not softirq_activated && active_mask & HRTIMER_ACTIVE_SOFT Then |
574 | active = active_bases & HRTIMER_ACTIVE_SOFT |
575 | softirq_next_timer = NULL |
579 | next_timer = softirq_next_timer |
582 | If active_mask & HRTIMER_ACTIVE_HARD Then |
583 | active = active_bases & HRTIMER_ACTIVE_HARD |
584 | next_timer = next_timer |
589 | Return expires_next |
