cpupower 工具
查看所有可用的模块，运行以下命令：
ls /usr/lib/modules/$(uname -r)/kernel/drivers/cpufreq/查询到 CPU 的信息
cpupower frequency-info
| 名称 | 说明 |
| driver | 当前使用的驱动 |
| hardware limits | cpu的频率可调范围 |
| available cpufreq governors | 硬件支持有效调速器 |
| current policy | 当前的电源计划 |
| current CPU frequency | 当前的CPU频率速度 |
设置最大时钟频率（CLOCK_FREQ 为时钟频率，单位为：GHz, MHz）
#cpupower frequency-set -u CLOCK_FREQ
cpupower frequency-set -u 1GHz
cpupower frequency-set -u 800MHz设置最小时钟频率
#cpupower frequency-set -d CLOCK_FREQ
cpupower frequency-set -d 1GHz
cpupower frequency-set -d 800MHz设置运行于指定频率
#cpupower frequency-set -f CLOCK_FREQ调整调速器
cpupower frequency-set -g governor
cpupower frequency-set -g ondemand参考
