函数名称：Reprogram the event source with checking both queues for the* next event* Called with interrupts disabled and base->lock held

函数原型：static void hrtimer_force_reprogram(struct hrtimer_cpu_base *cpu_base, int skip_equal)

返回类型：void

参数：

类型参数名称
struct hrtimer_cpu_base *cpu_base
intskip_equal
635  expires_next等于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
637  如果next_timer且is_soft则
643  如果softirq_activated则expires_next等于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
646  否则softirq_expires_next等于expires_next
650  如果skip_equal且expires_next恒等于expires_next则返回
653  expires_next等于expires_next
672  如果非Is the high resolution mode active ?或hang_detected则返回
675  tick_program_event(expires_next, 1)

名称描述
__remove_hrtimer__remove_hrtimer - internal function to remove a timer* Caller must hold the base lock.* High resolution timer mode reprograms the clock event device when the* timer is the one which expires next. The caller can disable this by setting* reprogram to zero
