函数名称：lockevents_register_device - register a clock event device*@dev: device to register

函数原型：void clockevents_register_device(struct clock_event_device *dev)

返回类型：void

参数：

类型参数名称
struct clock_event_device *dev
449  clockevent_set_state(dev, CLOCK_EVT_STATE_DETACHED)
451  如果非cpumask则
452  WARN_ON(num_possible_cpus() > 1)
453  cpumask等于cpumask_of - the cpumask containing just a given cpu*@cpu: the cpu (<= nr_cpu_ids)(当前cpu ID())
456  如果cpumask恒等于cpu_all_mask则
457  WARN(1, "%s cpumask == cpu_all_mask, using cpu_possible_mask instead\n", name)
459  cpumask等于cpu_possible_mask
462  raw_spin_lock_irqsave( & Protection for the above , flags)
464  添加链表项
465  Check, if the new registered device should be used. Called with* clockevents_lock held and interrupts disabled.
466  Called after a notify add to make devices available which were* released from the notifier call.
