Has anybody had a go at getting perf timechart up and running, perf
report and friends work fine but perf timechart just gives me an unknown
usage option. I assume I may need some extra kernel config options
selected, I'm using the beaglebone kernel.
Regards,

I've debugged a bit further and this is the error:
invalid or unsupported event: 'power:cpu_frequency'
I assume this is the signal that is not enabled in the kernel, does the
beaglebone have support for this signal?
