我试图让我的 CPU 保持在 2.0GHz（为了保持 CPU 凉爽 XD）或更高，并使用保守的调速器，为此尝试使用以下方法为我的 CPU 配置最低频率cpu频率设置
使用按需调节器时，我需要获得正确的频率，以将所有 CPU 限制为最低 2.00 GHz
以下是收集的一些信息：
cpufreq-info -g
conservative ondemand userspace powersave performance
所有 CPU 都从 coufreq-info 返回相同的信息

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 1.20 GHz - 2.67 GHz
available frequency steps: 2.67 GHz, 2.67 GHz, 2.53 GHz, 2.40 GHz, 2.27 GHz, 2.13 GHz, 2.00 GHz, 1.87 GHz, 1.73 GHz, 1.60 GHz, 1.47 GHz, 1.33 GHz, 1.20 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 1.20 GHz and 2.67 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.20 GHz.

答案1
使用提供的值cpu频率设置
cpufreq-set -d 2.00 GHz
