Title: Apparatus and method for enumeration of processors during hot-plug of a compute node

Abstract: An apparatus and method for enumeration of processors during hot-plug of a compute node are described. The method includes the enumeration, in response to a hot-plug reset, of one or more processors. The enumeration is provided to a system architecture operating system in which a compute node is hot-plugged. Once enumeration is complete, the compute node is started in response to an operating system activation request. Accordingly, once device enumeration, as well as resource enumeration are complete, the one or more processors of the processor memory node are activated, such that the operating system may begin utilizing the processors of the hot-plugged compute node.
