System Memory Management Unit Architecture For Consolidated Management Of Virtual Machine Stage 1 Address Translations
Abstract:
Various aspects include computing device methods for managed virtual machine memory access. Various aspects may include receiving a memory access request from a managed virtual machine having a virtual address, retrieving a first physical address for a stage 2 page table for a managing virtual machine, in which the stage 2 page table is stored in a physical memory space allocated to a hypervisor, retrieving a second physical address from an entry of the stage 2 page table for a stage 1 page table for a process executed by the managed virtual machine, in which the second physical address is for a physical memory space allocated to the managing virtual machine and the stage 1 page table is stored in that physical memory space, and retrieving a first intermediate physical address from an entry of the stage 1 page table for a translation of the virtual address.
