Apparatus and method for pattern-driven page table shadowing for graphics virtualization

A system comprising:

• a memory to store data and program code;
• a central processing unit (CPU) comprising an instruction cache for caching a portion of the program code and a data cache for caching a portion of the data, the CPU further comprising execution logic to execute the program code and responsively process the data, at least a portion of the program code comprising graphics commands;
• a graphics processing unit (GPU) to process the 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.
