  • Patent number: 10572434
    Abstract: A mechanism for enumerating Peripheral Component interconnect (PCI) Express (PCIe) devices within a data processing system is provided. Responsive to a reset of the data processing system, Peripheral Component interconnect (PCI) enumeration information for a set of PCIe devices coupled to the data processing system is read from a processor register. The PCI enumeration information is stored in an address space. PCI enumeration of the PCIe devices is skipped and the PCI enumeration information stored in the address space is presented to the operating system (OS) of the data processing system in order that the OS maintaining the PCIe devices using the PCI enumeration information.
