函数名称：Event handler for periodic broadcast ticks

函数原型：static void tick_handle_periodic_broadcast(struct clock_event_device *dev)

返回类型：void

参数：

类型参数名称
struct clock_event_device *dev
320  td等于this_cpu_ptr( & Tick devices)
323  raw_spin_lock( & tick_broadcast_lock)
326  如果clockevent_state_shutdown(evtdev)则
327  raw_spin_unlock( & tick_broadcast_lock)
328  返回
331  bc_local等于Periodic broadcast:* - invoke the broadcast handlers
333  如果clockevent_state_oneshot(dev)则
334  next等于计算下一次触发时间(next_event, tick_period)
336  设置下一次触发时间
338  raw_spin_unlock( & tick_broadcast_lock)
345  如果bc_local则event_handler(evtdev)
