  • Patent number: 9069622
    Abstract: Exemplary techniques for balancing 3D graphical processor unit use among virtual machines are herein disclosed. In an exemplary embodiment, a virtualization platform can load an instance of a graphics rendering module for a virtual machine; select a GPU for the graphics rendering module to run on; and configure the virtual machine to render to the selected GPU. In addition to the foregoing, other aspects are described in the detailed description, claims, and figures.

  • Patent number: 8941671
    Abstract: The present invention extends to methods, systems, and computer program products for providing domain, hull, and geometry shaders in a para-virtualized environment. As such, a guest application executing in a child partition is enabled use a programmable GPU pipeline of a physical GPU. A vGPU (executing in the child partition) is presented to the guest application. The vGPU exposes DDIs of a rendering framework. The DDIs enable the guest application to send graphics commands to the vGPU, including commands for utilizing a domain shader, a hull shader, and/or a geometric shader at a physical GPU. A render component (executing within the root partition) receives physical GPU-specific commands from the vGPU, including commands for using the domain shader, the hull shader, and/or the geometric shader. The render component schedules the physical GPU-specific command(s) for execution at the physical GPU.
