函数原型：static void sugov_iowait_boost(struct sugov_cpu *sg_cpu, u64 time, unsigned int flags)

返回类型：void

参数：

类型参数名称
struct sugov_cpu *sg_cpu
u64time
unsigned intflags
347  set_iowait_boost等于flags按位与Interface between cpufreq drivers and the scheduler:
350  如果iowait_boost且sugov_iowait_reset() - Reset the IO boost status of a CPU则返回
355  如果非set_iowait_boost则返回
359  如果iowait_boost_pending则返回
361  iowait_boost_pending = true
364  如果iowait_boost则
365  iowait_boost等于min_t - return minimum of two values, using the specified type*@type: data type to use*@x: first value*@y: second value(unsignedint, iowait_boost << 1, SCHED_CAPACITY_SCALE)
367  返回
371  iowait_boost等于IOWAIT_BOOST_MIN
