查看当前的策略：cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor 查看当前CPU频率：cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq 获取所有CPU的信息：cpupower -c all frequency-info 将所有CPU设置为性能模式：cpupower -c all frequency-set -g performance 切换...
1、查看当前所有CPU的信息 cpupower -c all frequency-info 2、设置所有CPU为性能模式 cpupower -c all frequency-set -g performance 3、设置所有CPU为节能模式 cpupower -c all frequency-set -g powersave 总结 如果是笔记本需要节能模式，直接安装tlp即可，默认策略，就可以省电了。如果是服务器，一定...

current CPU frequency: 2.10 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes performance: 顾名思义只注重效率,将CPU频率固定工作在其支持的最高运行频率上,而不动态调节。 Userspace:最早的cpufreq子系统通过userspace governor为用户提供了这种灵活性。系统将变频策略的决策权...
frequency-info 频率信息 frequency-set 后跟设置模式 参考实例 查看当前CPU的全部主频信息: [root@linuxcool ~]# cpupower -c all frequency-info 设置当前CPU为性能模式: [root@linuxcool ~]# cpupower -c all frequency-set -g performance 设置当前CPU为节能模式: [root@linuxcool ~]# cpupower -c all ...
通过以上步骤,你应该能够确定CentOS 8.5系统上的CPU是否是性能模式。如果需要调整CPU模式,可以使用cpupower frequency-set命令来更改scaling governor,例如: bash sudo cpupower frequency-set -g performance 这将把所有CPU核心设置为性能模式。
cpupower frequency-set -g performance 运行cpupowe命令检查,发现CPU的驱动为acpi-cpufreq,能够正常睿频的节点为intel_pstate。 异常节点运行命令:cpupower frequency-info analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 ...
