cpufreq-info命令用于查看和调整CPU频率设置。通过查看和调整CPU频率,可以实现节能和降低功耗。您可以按照以下步骤使用cpufreq-info命令: (1)首先,确保您的系统已经安装了cpufrequtils工具。您可以通过以下命令进行安装: sudo apt-get install cpufrequtils (2)在终端中输入以下命令以查看CPU频率设置: cpufreq-info (...
Reboot the system for the change to take effect. Note: Disabling CPU power saving states in the system BIOS has no effect on Linux. In some cases, performance can also be improved by adjusting the idle kernel parameter. However, care should be taken when using certain values. For example, ...
