Abstract:
A method for assigning system resources to an adapter circuit for a hot insertion of the adapter circuit to a computer bus of a computer system comprising:determining a lowest assigned value assigned to a device on the computer bus of a system resource reserved for the computer bus; determining a required quantity of the system resource required by the adapter circuit; determining whether the system resource reserved for the computer bus has an adequate assignable capacity for the required quantity below the lowest assigned value; assigning to the adapter circuit a portion of the system resource located below the lowest assigned value if the system resource reserved for the computer bus is determined to have an adequate assignable capacity; wherein the lowest assigned value is located in an aperture of the system resource reserved for the computer bus, wherein the determining whether the system resource reserved for computer bus has an adequate assignable capacity further includes determining whether the aperture has an adequate assignable capacity for the required quantity; wherein the determining whether the system resource reserved for computer bus has an adequate assignable capacity for the required quantity further includes: determining, if the aperture does not have an adequate assignable capacity, whether a second aperture of the system resource reserved for the computer bus located below the aperture has an adequate assignable capacity.
