  • Virtualization of graphics resources and thread blocking
    Patent number: 8373714
    Abstract: Virtualization of graphics resources and thread blocking is disclosed. In one exemplary embodiment, a system and method of a kernel in an operating system including generating a data structure having an identifier of a graphics resource assigned to a physical memory location in video memory, and blocking access to the physical memory location if a data within the physical memory location is in transition between video memory and system memory wherein a client application accesses memory in the system memory directly and accesses memory in the video memory through a virtual memory map.

  • Virtualization of graphics resources
    Patent number: 8094161
    Abstract: Graphics resources are virtualized through an interlace between graphics hardware and graphics clients. The interface allocates the graphics resources across multiple graphics clients, processes commands for access to the graphics resources from the graphics clients, and resolves conflicts for the graphics resources among the clients.
