{已解决}cpu频率自动调节问题请教

种过一豆

刚装完arch几天，有点小问题，没有装调节软件的时候一直维持在2GHz，装了调节软件后能把cpu频率调节到最低，问题在于编译软件的时候好像cpu没有自动调整到我设定的最高阈值，不知道哪还没有设置好

以下是cpu在编译的时候显示的信息，没有自动调整到我设定的1.33GHz

以下是设置

/etc/conf.d/cpufreq
# valid suffixes: Hz, kHz (default), MHz, GHz, THz
min_freq="1000MHz"
max_freq="1.33GHz"

如果把1.33GHz换成2好像又可以上升到2GHz的频率，上面显示的cpu可以用的调节段里面有1.33GHz，困惑

在/etc/conf.d/cpufreq中加入
governor="ondemand"
按需自动调整

已经加了这条ondemand

设置成1.34

cpufreq支持1.33GHz，cpu不一定支持
像我的t6570就只支持1.2，1.6，2.1三档

算了，不去想了，设成1.67能看到跑在1.33位置的时候，直接最高到2GHz得了，谢谢解答

wiki里面搜一下laptop-mod
按教程装好就行了～
