Abstract: An apparatus and method are described for implementing memory management in a graphics processing system. For example, one embodiment of an apparatus comprises: a first plurality of graphics processing resources to execute graphics commands and process graphics data; a first memory management unit (MMU) to communicatively couple the first plurality of graphics processing resources to a system-level MMU to access a system memory; a second plurality of graphics processing resources to execute graphics commands and process graphics data; a second MMU to communicatively couple the second plurality of graphics processing resources to the first MMU; wherein the first MMU is configured as a master MMU having a direct connection to the system-level MMU and the second MMU comprises a slave MMU configured to send memory transactions to the first MMU, the first MMU either servicing a memory transaction or sending the memory transaction to the system-level MMU on behalf of the second MMU.

Abstract: In an embodiment, a system includes a graphics processing unit (GPU) that includes one or more GPU engines, and a microcontroller. The microcontroller is to assign a respective schedule slot for each of a plurality of virtual machines (VMs). When a particular VM is scheduled to access a first GPU engine, the particular VM has exclusive access to the first GPU engine. Other embodiments are described and claimed.
