Abstract
Embodiments of an invention using cached dirty bits for context switch consistency checks are disclosed. In one embodiment, a processor includes control logic and a cache. The control logic is to cause a consistency check to be performed on a subset of a plurality of state components during a first context switch. The cache is to store a dirty entry for each state component to indicate whether the corresponding state component is included in the subset.
