SYNCHRONIZATION BETWEEN TRANSLATION LOOK-ASIDE BUFFER AND EXTENSION PAGING TABLE

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of performing efficient address conversion in a virtual machine.

SOLUTION: A processor 318 includes logic 322 for executing an instruction for synchronizing mapping stored in a translation look-aside buffer (TLB) 323 from system guest physical address (guest physical address) based on virtualization up to system host physical address (host physical address) based on virtualization with corresponding mapping stored in a system extension paging table (EPT) 328 based on virtualization.
