Method, System, and Apparatus for Dynamic Reconfiguration of Resources
First Claim
1. A method for on-line addition of an individual resource comprising:
- setting up physical and logical information for the individual resource;
defining serial links between a running system(RS) and the individual resource;
setting a path to a firmware;
running self test and initialization on the individual resource;
indicating to firmware execution on the RS that the individual resource is ready to join at least one partition; and
indicates to an operating system (OS) on the RS that the individual resource is ready to join at least one partition.

Abstract
A dynamic reconfiguration to include on-line addition, deletion, and replacement of individual modules of to support dynamic partitioning of a system, interconnect (link) reconfiguration, memory RAS to allow migration and mirroring without OS intervention, dynamic memory reinterleaving, CPU and socket migration, and support for global shared memory across partitions is described. To facilitate the on-line addition or deletion, the firmware is able to quiesce and de-quiesce the domain of interest so that many system resources, such as routing tables and address decoders, can be updated in what essentially appears to be an atomic operation to the software layer above the firmware.
