如果自己看还有问题，把cpux目录下的文件打包，并且将bios设定画面拍照，一起传上来。再详细说明一下硬件配置。

还有以下命令的输出：

代码： 全选

我看了下 /sys/devices/system/cpu/cpu2/cpufreq 里面的内容，其中 scaling_governor 的内容是 powersave，而 scaling_available_governors 里的内容是 performance powersave。scaling_max_freq 里面的值是 3200000，scaling_min_freq 里面的值是 1200000。

是不是把 scaling_governor 的值改成 performance 就可以了？不过，这样会不会强行把cpu的频率什么时候都设成最高的？这也不是我想要的结果。

bios 的设定没有拍照，您要的命令结果如下：

dsmeg 输出很多，都要贴吗？

谢谢！
