That's fantastic:
# sudo cpupower -c 99 frequency-info info
analyzing CPU 99:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 99
CPUs which need to have their frequency coordinated by software: 99
maximum transition latency: Cannot determine or is not supported.
hardware limits: 1.50 GHz - 3.72 GHz
available frequency steps: 2.00 GHz, 1.70 GHz, 1.50 GHz
available cpufreq governors: conservative ondemand userspace powersave
performance schedutil
current policy: frequency should be within 1.50 GHz and 3.72 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency: 2.00 GHz (asserted by call to hardware)
boost state support:
Supported: yes
Active: yes
Boost States: 0
Total States: 3
Pstate-P0: 2000MHz
Pstate-P1: 1700MHz
Pstate-P2: 1500MHz
