Abstract:
A computing device that handles address translations is described. The computing device includes a hardware table walker and a memory that stores a reverse map table and a plurality of pages of memory. The table walker is configured to use validated indicators in entries in the reverse map table to determine if page accesses are made to pages for which entries are validated. The table walker is further configured to use virtual machine permissions levels information in entries in the reverse map table determine if page accesses for specified operation types are permitted.

Claim (Index 10):
A computing device, comprising:\n a processor; a hardware table walker; and a memory that stores a reverse map table (RMT), a page table, and a plurality of pages of memory; wherein the table walker is configured to:\n receive, based on an access request from a virtual machine, a request to translate a guest virtual address into a system physical address associated with a page of memory; \n use a guest physical address associated with the guest virtual address to acquire the system physical address from a corresponding entry in the page table; \n perform a permissions check to determine whether an entry in the RMT associated with the system physical address indicates that the virtual machine has permission to perform an operation type indicated in the access request; and \n based on an outcome of the permissions check, selectively provide the system physical address for use in performing the access for the virtual machine.
