[Mesa-dev] [PATCH] gallium/hud: Add power sensor support

Thu Sep 29 14:11:31 UTC 2016
Implement support for power based sensors, reporting units in
milli-watts and watts.
Also, minor cleanup - change the related if block to a switch.
Tested with two different power sensors, including the nouveau
'power1' sensors on a GTX950 card.
