Virtual memory system

An information handling system (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a virtual memory engine that includes a Basic Input/Output System (BIOS) and a runtime service and that is configured to:
• create, during an initialization process and in a virtual memory database using a first global unique identifier, virtual memory by mapping a continuous virtual memory address range to interleaved physical memory device address ranges that are provided across a plurality of physical memory devices;
• define, in the virtual memory database using a second global unique identifier, a virtual memory device namespace in the virtual memory that includes a first continuous subset of the continuous virtual member address range, wherein the BIOS is configured to define the virtual memory namespace identifier during the initialization process and in the virtual memory database using the second global unique identifier, and wherein the runtime service is configured to define the virtual memory namespace subsequent to the initialization process and during runtime in the virtual memory database using the second global unique identifier;
• and
• provide, during runtime, read and write block mode access to the plurality of physical memory devices via the virtual memory device namespace defined in the virtual memory database.

A method for providing virtual memory, comprising:

• creating, by a computing device during an initialization process and in a virtual memory database using a first global unique identifier, virtual memory by mapping a continuous virtual memory address range to interleaved physical memory device address ranges that are provided across a plurality of physical memory devices;
• defining, by the computing device in the virtual memory database using a second global unique identifier, a virtual memory device namespace in the virtual memory that includes a first continuous subset of the continuous virtual member address range, wherein the defining includes:
• defining, by a Basic Input/Output System (BIOS) in the computing device during the initialization process, the virtual memory namespace in the virtual memory database using the second global unique identifier;
• and
• defining, by a runtime service in the computing device subsequent to the initialization process and during runtime, the virtual memory namespace in the virtual memory database using the second global unique identifier;
• and
• providing, by the computing device during runtime, read and write block mode access to the plurality of physical memory devices via the virtual memory device namespace defined in the virtual memory database.
