analyzing CPU 0:
driver: BCM2835 CPUFreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 355 us.
hardware limits: 700 MHz - 1000 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 700 MHz and 1000 MHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency is 700 MHz (asserted by call to hardware).
