在linux系统下cpu的turbo功能被关闭了,cpupower下的大致情况:
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: Cannot determine or is not supported.
hardware limits: 1.40 GHz - 1.80 GHz
available frequency steps: 1.80 GHz, 1.70 GHz, 1.40 GHz
available cpufreq governors: powersave performance schedutil
current policy: frequency should be within 1.40 GHz and 1.80 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 1.40 GHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: no

通过忽略主板上的cpu频率的限制也没有办法正常睿频,有没有碰到过相同情况解决了的网友,希望能提供下你的方案,万分感谢。
