Web故cpufreq作为中间层,向上抽象了处理器变频的具体实现,向下分离了变频的策略。将具体的策略和变频的物理上实现进行分离。 这种设计带来的好处是使得 governor 和 CPU 相关的变频驱动程序的开发可以相互独立进行,并在最大限度上实现代码重用,内核开发人员在编写和试验新的 governor 时不会再 ... WebMar 10, 2024 · Nope, not running any cpufreq utilities, besides indicator-cpufreq, which I uninstalled for the sake of controlling for it. The grep command keeps returning powersave, not performance. So frustrating, why!? Not sure why, but using indicator-cpufreq, when I switch to performance, the grep command spits out performance, which is a step forward.
