Abstract
A method for tagging cache entries to support context switching for virtual machines and for operating systems. The method includes, storing a plurality of entries within a cache of a CPU of a computer system, wherein each of the entries includes a context ID, handling a first portion of the entries as local entries when the respective context IDs indicate a local status, and handling a second portion of the entries as global entries when the respective context IDs indicate a global status.
