Graphics Render C-State
Render C-State (RC6) is a technique designed to optimize the average power to the
graphics render engine during times of idleness of the render engine. Render C-state is
entered when the graphics render engine, blitter engine and the video engine have no
workload being currently worked on and no outstanding graphics memory transactions.
When the idleness condition is met, the integrated graphics will program the graphics
VR into a low voltage state through the GFX_VID signals.
