禁用 CPU 频率调节 Ubuntu 20.04

Question

我正在使用 Ubuntu 20.04，并且本教程禁用 CPU 频率调整。

我已经做好了：

sudo systemctl disable ondemand
sudo systemctl enable cpufrequtils
sudo sh -c 'echo "GOVERNOR=performance" > /etc/default/cpufrequtils'
sudo systemctl daemon-reload && sudo systemctl restart cpufrequtils

然后重启GOVERNOR然后我检查了每个 CPU的状态0-->11，看到模式为performance，现在当我使用检查时，$ cpufreq-info我得到：

analyzing CPU 11:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 11
  CPUs which need to have their frequency coordinated by software: 11
  maximum transition latency: 4294.55 ms.
  hardware limits: 800 MHz - 4.10 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 800 MHz and 4.10 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz.

对于所有 CPU 来说都是一样0 --> 11，您能告诉我如何正确禁用 CPU 频率缩放吗？提前致谢。
