4.5 Integrated Graphics Power Management

4.5.1 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.
