函数名称：herm_throt_process - Process thermal throttling event from interrupt*@curr: Whether the condition is current or not (boolean), since the* thermal interrupt normally gets called both when the thermal* event begins and once the event has ended

函数原型：static void therm_throt_process(bool new_event, int event, int level)

返回类型：void

参数：

315  this_cpu等于当前cpu ID()
318  pstate等于per_cpu(thermal_state, this_cpu)
320  now等于get_jiffies_64()
321  如果level恒等于CORE_LEVEL则
322  如果event恒等于THERMAL_THROTTLING_EVENT则state等于core_throttle
324  否则如果event恒等于POWER_LIMIT_EVENT则state等于core_power_limit
326  否则返回
328  否则如果level恒等于PACKAGE_LEVEL则
329  如果event恒等于THERMAL_THROTTLING_EVENT则state等于package_throttle
331  否则如果event恒等于POWER_LIMIT_EVENT则state等于package_power_limit
333  否则返回
335  否则返回
338  old_event等于new_event
339  new_event等于new_event
341  如果new_event则count自加
344  如果event不等于THERMAL_THROTTLING_EVENT则返回
347  如果new_event且非last_interrupt_time则
351  get_therm_status(level, & hot, & temp)
357  如果temp大于10则返回
360  baseline_temp等于temp
361  last_interrupt_time等于now
362  schedule_delayed_work_on - queue work in global workqueue on CPU after delay*@cpu: cpu to use*@dwork: job to be done*@delay: number of jiffies to wait* After waiting for a given time this puts a job in the kernel-global* workqueue on the specified CPU.
363  否则如果old_event且last_interrupt_time则
366  throttle_time等于jiffies_delta_to_msecs(now - last_interrupt_time)
367  如果throttle_time大于max_time_ms则max_time_ms等于throttle_time
369  total_time_ms加等于throttle_time
370  last_interrupt_time等于0
