sudo cpupower -c all frequency-info
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: Cannot determine or is not supported.
hardware limits: 800 MHz - 3.00 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 3.00 GHz and 3.00 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency: 2.29 GHz (asserted by call to hardware)
boost state support:
Supported: yes
Active: yes
analyzing CPU 1:
driver: intel_pstate
CPUs which run at the same hardware frequency: 1
CPUs which need to have their frequency coordinated by software: 1
maximum transition latency: Cannot determine or is not supported.
hardware limits: 800 MHz - 3.00 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 800 MHz and 3.00 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: 2.28 GHz (asserted by call to hardware)
boost state support:
Supported: yes
Active: yes
analyzing CPU 2:
driver: intel_pstate

maximum transition latency: Cannot determine or is not supported.
hardware limits: 800 MHz - 3.00 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 800 MHz and 3.00 GHz.
The governor "performance" may decide which speed to use
within this range.
