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 15):
The computing device of  claim 14 , wherein the one or more additional checks further comprise one or more of:\n checking an assigned indicator in the entry to determine whether the entry is marked as being currently in use; checking an identifier in the entry that identifies a previously-accessing virtual machine to determine whether the virtual machine matches the previously-accessing virtual machine; and checking a recorded page size in the entry that indicates a size of a page of memory associated with the system physical address to determine whether a page size indicated in the access request matches the recorded page size, wherein the virtual machine has access to the page of memory when the entry is marked as being currently in use, the virtual machine matches the previously-accessing virtual machine, and the page size matches the recorded page size.
