ASYMMETRIC CO-EXISTENT ADDRESS TRANSLATION STRUCTURE FORMATS

摘要

An address translation capability is provided in which translation structures of different types are used to translate memory addresses from one format to another format. Multiple translation structure formats (e.g., multiple page table formats, such as hash page tables and hierarchical page tables) are concurrently supported in a system configuration. This facilitates provision of guest access in virtualized operating systems, and/or the mixing of translation formats to better match the data access patterns being translated.
