Abstract:
A processing system includes a processing core to execute a virtual machine (VM) comprising a guest operating system (OS) and a memory management unit, communicatively coupled to the processing core, comprising a storage device to store an extended page table entry (EPTE) comprising a mapping from a guest physical address (GPA) associated with the guest OS to an identifier of a memory frame, a first plurality of access right flags associated with accessing the memory frame in a first page mode referenced by an attribute of a memory page identified by the GPA, and a second plurality of access right flags associated with accessing the memory frame in a second page mode referenced by the attribute of the memory page identified by the GPA.
