Abstract:
1. A computer implemented method for retrieving location information in a data processing system, the computer implemented method comprising: booting a first at least one service processor controlling at least one Peripheral Component Interconnect Express (PCIe) card in an I/O unit; booting a second at least one service processor located in a processor unit, wherein the processor unit and the I/O unit are interconnected using functional path conductors, wherein functional path conductors are according to Peripheral Component Interconnect Express (PCIe) standard; reading location information from the first at least one service processor, wherein the location information is reported for each PCIe card in the I/O unit prior to initializing a functional path to the PCIe card, wherein reading is at the second at least one service processor; responsive to reading location information, sending location information from the second at least one service processor to a system controller; responsive to collecting location information, initializing the PCIe card and a hub card of the processor unit in order to initialize a functional path; and configuring the I/O unit by communicating configuration commands over the functional path connected to the PCIe card.
