First of all, Sorry if I am posting my thread on the wrong platform.
I want to change the cpu frequency. I have install cpufrequtils. the command "cpufreq-info" give me information
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to firstname.lastname@example.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.
when I try to run the command: "sudo cpufreq-set -f 1500000". I am getting error: 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?
Can you give any idea how to approach this problem?
