Apparatus and method for efficient localdisplay sharing for a virtualized graphics processor

A method comprising:

• executing host instructions to implement a host and a virtualized execution environment comprising a plurality of virtual machines (VMs);
• executing graphics instructions by graphics execution circuitry to render framebuffers on behalf of each VM, each framebuffer associated with a virtual function (VF);
• dynamically mapping a framebuffer to one or more display planes of a display engine, wherein dynamically mapping comprises generating a framebuffer object with framebuffer information required by a physical function (PF) of the host to update the one or more display planes.

A machine-readable medium having program code stored thereon which, when executed by a machine, causes the machine to perform the operations of:

• executing host instructions to implement a host and a virtualized execution environment comprising a plurality of virtual machines (VMs);
• executing graphics instructions by graphics execution circuitry to render framebuffers on behalf of each VM, each framebuffer associated with a virtual function (VF);
• dynamically mapping a framebuffer to one or more display planes of a display engine, wherein dynamically mapping comprises generating a framebuffer object with framebuffer information required by a physical function (PF) of the host to update the one or more display planes.
