(P)->sleep_avg) * Max_bonus/\ MAX_SLEEP_AVG) As you can see, the process description character also has a sleep_avg, and the dynamic compensation is entirely based on its value. Sleep_avg is the key, which represents the time that the process sleeps and runs, and when the process goes from hibernation to runtime, Sleep_avg adds the time it takes to hibernate. At run time, each clock beat Sleep_avg is decremented until 0. So, the bigger the sleep_avg, the greater the dynamic priority co
