ABSTRACT:
A computing device has a graphics hardware device employed to display graphics on a display, and is partitioned to include a video services partition (VSP) instantiated at least in part to provide graphics capabilities, and also to include a video client partition (VCP) instantiated at least in part to consume such graphics capabilities. The graphics hardware device is assigned to and controlled by the VSP. A shared video memory module is shared by the VCP and the VSP such that graphics information placed in the pages shared by the video memory module by the VCP is directly available to the VSP for further action such that graphics commands from the VCP are shunted by way of the pages shared by the video memory module across partitions from the VCP to the VSP to be acted upon by the graphics hardware device as controlled by the VSP.
