Abstract

Embodiments include a system for dynamic universal port mode assignment for a general purpose computer system. A host bridge with a mixed mode request router receives requests over a universal peripheral component interconnect express (PCIe) port from PCIe adapters utilizing different operating modes. An aspect includes a general purpose host computer with one or more PCIe universal ports allowing the computer to connect to a wide range of external peripheral devices, such as a local area networks, storage area networks, printers, scanners, graphics controllers, game systems, and so forth. PCIe is a modern universal port protocol for parallel ports that allows peripherals utilizing different operating modes to connect to a standard PCIe parallel port. The mixed mode request router supports converged PCIe adapters, which support multiple functions utilizing different PCIe modes converged onto the same mixed mode adapter.
