在intel_pstate cpu上设置调控器

我正在尝试sudo echo 100 > /sys/devices/system/cpu/intel_pstate/min_perf_pct

或通过sudo cpupower -c 1 frequency-set -g performance

更改州长

但没有一个可行,第二个告诉我没问题,但是当我查看频率信息时,我得到的频率最低,调控器仍然是performance, powersave

analyzing CPU 1: driver: intel_pstate CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 0.97 ms. hardware limits: 1.20 GHz - 2.60 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 1.20 GHz and 2.60 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency is 1.20 GHz (asserted by call to hardware). boost state support: Supported: no Active: no 2600 MHz max turbo 4 active cores 2600 MHz max turbo 3 active cores 2600 MHz max turbo 2 active cores 2600 MHz max turbo 1 active cores
