analyzing CPU 0:
driver: BCM2835 CPUFreq
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: 355 us.
hardware limits: 600 MHz - 1.40 GHz
available frequency steps: 600 MHz, 1.40 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance, schedutil
current policy: frequency should be within 600 MHz and 1.40 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 600 MHz.
cpufreq stats: 600 MHz:97.19%, 1.40 GHz:2.81% (78)
