Abstract
A processing system includes a processor core for processing instructions and a memory that stores a page table set including an extended page table having an extended page table entry storing extended page table attributes associated with a physical memory page. The system receives a virtual address and translates the virtual address to a physical address for the physical memory page. One or more extended page attributes associated with the physical memory page are retrieved from the extended page table entry based on the virtual address.
