Apparatus and method for pattern-driven page table shadowing for graphics virtualization
Abstract:
An apparatus and method are described for pattern driven page table updates. For example, one embodiment of an apparatus comprises a graphics processing unit (GPU) to process graphics commands and responsively render a plurality of image frames; a hypervisor to virtualize the GPU to share the GPU among a plurality of virtual machines (VMs); a first guest page table managed within a first VM, the first guest page table comprising a plurality of page table entries; a first shadow page table managed by the hypervisor and comprising page table entries corresponding to the page table entries of the first guest page table; and a command parser to analyze a current working set of commands submitted from the first VM to the GPU, the command parser to responsively update the first shadow page table responsive to determining a set of page table entries predicted to be used based on the analysis of the working set of commands.
