Abstract
Managing translation invalidation includes: in response to determining that a first invalidation message (IM) applies to a subset of virtual addresses (VAs) consisting of fewer than all VAs associated with a first set of translation context (TC) values, searching VA-indexed structure(s) to find and invalidate any entries that correspond to a VA in the subset; in response to determining that a second IM applies to all VAs associated with a second set of TC values and that no entry exists in invalidation-tracking structure(s) corresponding to the second set, bypassing searching any VA-indexed structure(s); and in response to determining that a third IM applies to all VAs associated with a third set of TC values and that at least one entry exists in the invalidation-tracking structure(s) corresponding to the third set, storing invalidation information in the invalidation-tracking structure(s) to invalidate the third set and delaying searching any VA-indexed structure(s).
