有关linux 中IPA的相关问题

wh_c

1.在linux-5.15.11/driver/thermal/gov_power_allocator.c中，PID三个参数计算如下

即

kpu = 2 * sustainable_power / (control_temperature - current_temperature)

kpo = sustainable_power / (control_temperature - current_temperature)

ki = kpu / 10

kd = 0

请问三个参数为什么这样计算，这样计算的意义在哪？

2.IPA从计算功率，分配功率到设置状态整个过程的周期大概是多少？

    上面公式描述错了，因该如下：

    kpu = 2 * sustainable_power / (control_temperature - switch on temperature)

    kpo = sustainable_power / (control_temperature - switch on temperature)

    ki = kpu / 10

    kd = 0
