[root@bupyc-notebook bupyc]# cpupower frequency-info
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: 4.0 us.
hardware limits: 1.40 GHz - 2.30 GHz
available frequency steps: 2.30 GHz, 2.00 GHz, 1.80 GHz, 1.60 GHz, 1.40 GHz
available cpufreq governors: userspace, ondemand, performance
current policy: frequency should be within 1.40 GHz and 1.84 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 1.80 GHz (asserted by call to hardware).
