Abstract
A recursive logical partition real memory map mechanism is provided for use in address translation. The mechanism, which is provided in a data processing system, receives a first address based on an address submitted from a process of a currently active logical partition. The first address is translated into a second address using a recursive logical partition real memory (RLPRM) map data structure for the currently active logical partition. The memory is accessed using the second address. The RLPRM map data structure provides a plurality of translation table pointers, each translation table pointer pointing to a separate page table for a separate level of virtualization in the data processing system with the data processing system supporting multiple levels of virtualization.
