Abstract
A system and method for performing dynamic partitioning operations within a data processing system is disclosed. According to one embodiment, the current invention provides a system that allows an unit to be added to an executing data processing partition. The partition may include a shared resource that is receiving requests from other units that are already included within the partition. The inventive system includes means for programmably enabling the unit to the shared resource. Once the unit is so enabled, the system synchronizes the request arbitration being performed by this unit with the arbitration activities occurring within other units requesting access to the shared resource. This synchronization process prevents two units from attempting to simultaneously access the shared resource.
