Hi,
Did you try compile the cpupower tool [1] which comes with the kernel?
cpupower frequency-info works as advertised on a 3.13.x kernel and a beagle
bone black
On a beagle-xm it shows similar problems, but ...
... I think it actually runs on 1GHz: cpufreq stats: 300 MHz:0.00%, 600
MHz:0.00%, 800 MHz:0.00%, 1000 MHz:100.00% (3)
and by mistake shows: current CPU frequency is 600 MHz (asserted by call
to hardware).
cpupower frequency-info
analyzing CPU 0:
driver: generic_cpu0
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 600 MHz (asserted by call to hardware).
cpufreq stats: 300 MHz:0.00%, 600 MHz:0.00%, 800 MHz:0.00%, 1000
MHz:100.00% (3)
Regards,
Robert
