Abstract
A system, method, and computer program product are disclosed for invalidating specified pretranslations maintained in a data processing system which maintains decentralized copies of pretranslations. A centralized mapping of virtual addresses to their associated physical addresses is established. The centralized mapping includes a listing of pretranslations of the virtual addresses to their associated physical addresses. Multiple lists of pretranslations are generated. Control of the lists may be passed from one entity to another, such that the lists are not owned by any particular entity. Each one of the lists includes a copy of pretranslations for virtual addresses. A particular one of the physical addresses is specified. Each list that includes a pretranslation of a virtual address to the specified physical addresses is located. The pretranslation of the virtual address to the specified physical address is then invalidated within each one of the lists.
