  • Migrating And Save Restoring A Virtual 3D Graphics Device

    view source
  • US Patent:
    20120056891, Mar 8, 2012
  • Filed:
    Sep 2, 2010
  • Appl. No.:
    12/874235
  • Inventors:
    Parag Chakraborty - Sunnyvale CA,
    Hao Zhang - Sunnyvale CA,
    Pareekshit Singh - Sunnyvale CA,
    Pandele Stanescu - Santa Clara CA,
  • Assignee:
    Microsoft Corporation - Redmond WA
  • International Classification:
    G06T 1/20
  • US Classification:
    345502, 345522
  • Abstract:
    A virtual graphics processing unit within a virtual machine may be restored by causing a reset to the virtual graphics processing unit. The state of the virtual graphics processing unit may not be saved during a migration or save and restore operation, but a reset of the virtual graphics processing unit may cause all applications with processes in the virtual graphics processing unit to re-start and thereby recreate the state of the virtual graphics processing unit. A hypervisor may include a separate graphics processor unit process that may present a virtual graphics processing unit to a virtual machine and communicate with a physical graphics processing unit in hardware. When a virtual machine may be restored after a save or migration, the hypervisor may cause the virtual graphics processor unit to reset and its state to be recreated.

  • US Patent:
    20130181999, Jul 18, 2013
  • Filed:
    Jan 13, 2012
  • Appl. No.:
    13/350246
  • Inventors:
    Meher Prasad Malakapalli - Santa Clara CA,
    Hao Zhang - Sunnyvale CA,
    Lin Tan - Cupertino CA,

  • Assignee:
    MICROSOFT CORPORATION - Redmond WA
  • International Classification:
    G06T 1/20
  • US Classification:
    345506
  • 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.

    20110102443, May 5, 2011
  • Filed:
    Dec 4, 2009
  • Appl. No.:
    12/631662

    Hao Zhang - Sunnyvale CA,

  • Assignee:

  • International Classification:
    G06T 1/00
  • US Classification:
    345522
  • Abstract:
    Methods and systems are disclosed for virtualizing a graphics accelerator such as a GPU. In one embodiment, a GPU can be paravirtualized. Rather than modeling a complete hardware GPU, paravirtualization may provide for an abstracted software-only GPU that presents a software interface different from that of the underlying hardware. By providing a paravirtualized GPU, a virtual machine may enable a rich user experience with, for example, accelerated 3D rendering and multimedia, without the need for the virtual machine to be associated with a particular GPU product.
