ABSTRACT:
In at least one embodiment, an apparatus for providing resources from a plurality of on-board device nodes to a hot-plugged device node in a computer is provided. The apparatus comprises a resource manager configured to receive a resource request over a bus system indicative of a set of desired resources from the hot-plugged device node. The resource manager is further configured to probe a parent device and at least one upper level device node positioned above the parent device node for the set of desired resources. The resource manager is further configured to provide the set of desired resources from the parent device node and one or more nodes of the at least one upper level device node over the bus system for transmission to the hot-plugged device node to enable the hot-plugged device node to operate in the intended manner.
