2017-11-22intel-gpu-overlay: Use RAPL PMU for power readingTvrtko Ursulin
Wire up to the RAPL PMU for GPU energy readings. The only complication is that we have to add code to parse: # cat /sys/devices/power/events/energy-gpu.scale 2.3283064365386962890625e-10 v2: Link with -lm. v3: strtod can handle scientific notation, even though my initial reading of the man page did not spot that. (Chris Wilson) v4: Meson fix. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>
