ABSTRACT:
A system and method for extending the use of the cross-memory descriptor in a server partition environment such that it may be used to describe another partition's memory, e.g., a client partition's memory (referred to hereafter as a “remote” memory), are provided. With the system and method, when an operating system in a logically partitioned computing system is initialized, operating system kernel services are invoked that examine a device tree of the computing system and generate an extended cross-memory descriptor that describes the local memory of another logical partition, which is a remote memory to the present logical partition. When an access to a remote memory is required to perform an operation, the operating system of the server partition uses the stored extended cross-memory descriptor to perform the remote memory access.
