Abstract:
A mechanism is provided, in a data processing system, for accessing memory based on an effective address submitted by a process of a partition. The mechanism may translate the effective address into a virtual address using a segment look-aside buffer. The mechanism may further translate the virtual address into a partition real address using a page table. Moreover, the mechanism may translate the partition real address into a system real address using a logical partition real memory map for the partition. The system real address may then be used to access the memory.
