Title:
GLOBAL VARIABLE MIGRATION VIA VIRTUAL MEMORY OVERLAY TECHNIQUE FOR MULTI-VERSION ASYNCHRONOUS DYNAMIC SOFTWARE UPDATE
Document Type and Number:
WIPO Patent Application WO/2018/218848
Kind Code:
A1
Abstract:
System and method for managing migration of global variables on processing system during live program updates, including creating a shared data segment is created in a physical memory of the processing system, binding a logical address space of a first global variable data segment for a first version of a program to a physical address of the shared data segment, and binding a logical address space for a second global variable data segment for an update version of the program to the physical address of the shared data segment. The first global variable data segment and the second global variable data segment exist concurrently and each map to common global variables stored in the shared data segment.
