--------------
analyzing CPU 3:
driver: intel_cpufreq
CPUs which run at the same hardware frequency: 3
CPUs which need to have their frequency coordinated by software: 3
maximum transition latency: 20.0 us
hardware limits: 800 MHz - 3.30 GHz
available cpufreq governors: conservative ondemand userspace powersave performance schedutil
current policy: frequency should be within 800 MHz and 3.30 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency: 1.23 GHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes
