Apparatus and method for display virtualization using mapping between virtual and physical display planes

A method comprising:

• rendering one or more graphics images on a set of graphics processing resources for executing graphics commands and rendering graphics images;
• and
• storing data related to a current set of virtual display planes and virtual display pipes within one or more registers, the virtual display pipes to process images to render on the one of the one or more virtual display planes;
• and
• assigning a first virtual machine (VM) to one or more of the virtual display planes and to maintain a mapping between the one or more virtual display planes and at least one physical display plane, wherein maintaining the mapping comprises a page walk using a requestor identifier (RID), and wherein the page walk comprises generating an index value from a plane identifier index data structure by performing a lookup using a plane identifier (ID) and generating the requestor identifier (RID) from a walker information data structure responsive to the index value.

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

• rendering one or more graphics images on a set of graphics processing resources for executing graphics commands and rendering graphics images to memory allocated to a specific RID;
• and
• storing data related to a current set of virtual display planes and virtual display pipes within one or more registers, the virtual display pipes to process images to render on the one of the one or more virtual display planes;
• and
• assigning a first virtual machine (VM) to one or more of the virtual display planes and to maintain a mapping between the one or more virtual display planes and at least one physical display plane, wherein maintaining the mapping comprises a page walk using a requestor identifier (RID), and wherein the page walk comprises generating an index value from a plane identifier index data structure by performing a lookup using a plane identifier (ID) and generating the requestor identifier (RID) from a walker information data structure responsive to the index value.
