Abstract
A method and system for hot-plugging a processor subsystem to a system bus of a data processing system while said data processing system is active, where the system bus comprises multiple positions for supporting hot-pluggable processor subsystems, where each processor subsystem includes a processor and associated voltage regulator module. Power is applied to a processor subsystem in response to an indication that the processor subsystem has been added to the system bus of the data processing system. Initialization routines are performed on the processor within the processor subsystem through a controller which transmits initialization data to the processor independent of the system bus, such that additional processor subsystems are integrated into the data processing system with minimal effect on any existing processors operating on the system bus.
