analyzing CPU 0:

CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 300 us.
hardware limits: 300 MHz - 1000 MHz
available frequency steps: 300 MHz, 600 MHz, 800 MHz, 1000 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 300 MHz and 1000 MHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 1000 MHz.
