[转帖]CPUpower的处理

用cpupower工具修改，但是在修改过程中会遇到ERROR：

[root@wyx~]# cpupower frequency-set -f 1.6G
Setting cpu: 0
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency

or because the userspace governor isn't loaded?

解决方法：

1. 在/etc/default/grub中加入 GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable"

2. 命令行输入：

grub2-mkconfig -o /boot/grub2/grub.cfg

或者 grub-mkconfig -o /boot/grub/grub.cfg

3. 重启机器 reboot（有些机器需要在bios里关掉超线程以及Pstate,Cstate，有些不用，可以试一试。）

4. 重启后输入命令：
cpupower frequency-info --governors
cpupower frequency-set -g conservative

5. 可以用cpupower的命令修改频率了

cpupower frequency-set -f 1.6G

修改完成。
