SYSTEM SUPPORTING MULTIPLE PARTITIONS WITH DIFFERING TRANSLATION FORMATS

摘要

A system configuration is provided with multiple partitions that supports different types of address translation structure formats. The configuration may include partitions that use a single level of translation and those that use a nested level of translation. Further, differing types of translation structures may be used. The different partitions are supported by a single hypervisor.

1. A computer program product for facilitating memory access, said computer program product comprising:
a non-transitory computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
providing a first partition within a system configuration, the first partition configured to support an operating system (OS) designed for a first address translation architecture, wherein configuration of the first partition to support the OS designed for the first address translation architecture is indicated in a configuration data structure, and wherein the first partition is not configured, as indicated in the configuration data structure, to support an OS designed for a second address translation architecture; andproviding a second partition within the system configuration, the second partition configured to support the OS designed for the second address translation architecture, the second partition not configured to support the OS designed for the first address translation architecture, wherein the first address translation architecture is structurally different from the second address translation architecture.
