Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: cpufreq-dt
CPUs which run at the same hardware frequency: 0 1 2 3
CPUs which need to have their frequency coordinated by software: 0 1 2 3
maximum transition latency: 7.04 ms.
hardware limits: 240 MHz - 1.20 GHz
available frequency steps: 240 MHz, 480 MHz, 648 MHz, 816 MHz, 912 MHz, 960 MHz, 1.01 GHz, 1.10 GHz, 1.20 GHz
available cpufreq governors: conservative, userspace, powersave, ondemand, performance, schedutil
current policy: frequency should be within 408 MHz and 1.20 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 480 MHz.

Любопытно, что частоты процессоров изменяются сильно коррелировано, но не синхронно, вразнобой!
