我想改变cpu频率。我已经安装了 cpufrequtils。命令“ cpufreq-info
”给我信息
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 0.97 ms.
hardware limits: 1.20 GHz - 2.40 GHz
available cpufreq governors: performance, powersave
current policy: frequency should be within 1.20 GHz and 2.40 GHz.
The governor "performance" may decide which speed to use
within this range.
当我尝试运行命令时:“ sudo cpufreq-set -f 1500000
”。我收到错误:
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?
你能告诉我如何解决这个问题吗?
