System resource assignment for a hot inserted device
A hot insertion system for assigning system resources of a computer system to a hot inserted adapter circuit such as a device mounted on a PCI adapter card. The adapter circuit is hot inserted to the computer system via a connector such as a slot connector. Apertures of a system resource such as I/O address space, memory address space, and interrupt numbers, are reserved for each computer bus of the computer system. The devices located on the computer bus are assigned portions of each system resource aperture in a top down configuration. A system resource assignment routine finds the lowest assigned address of a system resource aperture to determine whether the aperture has enough assignable capacity for a hot inserted adapter circuit. If enough assignable capacity exists, then the system resource assignment routine assigns a portion of each system resource aperture located below lowest assigned address to the adapter circuit.
