Abstract
Embodiments include techniques for using a zone-SDID mapping for translation lookaside buffer (TLB) purges, the embodiments include receiving a zone purge request, including zone attribute information, and searching for matching zone attribute information in a zone register using the zone purge request. Embodiments also include computing, based at least in part on the search, a state descriptor identifier (SDID) vector for each matching zone of the zone register, and reading TLB entries referenced in the zone purge request. Embodiments include comparing an SDID of the TLB entry against an SDID specified in the SDID vector, and purging the TLB entries based on the comparison.
