I need to figure out how I can query the various things and learn what they 
actually mean. F.e. on the frame.work forum I found:
`cat /sys/class/drm/card0/device/power/runtime_status`

and that returns 'active', but I have no idea what that means.

Like I said before: lots of research to do ;-)

Good to know :-)
