PCI Express Port Bus Configuration


  • Option: PCIEPORTBUS
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) PCI Express support
    • depends on PCI
      This automatically enables PCI Express Port Bus support. Users can choose Native Hot-Plug support, Advanced Error Reporting support, Power Management Event support and Virtual Channel support to run on PCI Express Ports (Root or Switch).
Include service Kconfig here


  • Option: HOTPLUG_PCI_PCIE
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) PCI Express Hotplug driver
    • depends on HOTPLUG_PCI && PCIEPORTBUS
      Say Y here if you have a motherboard that supports PCI Express Native Hotplug
      To compile this driver as a module, choose M here: the module will be called pciehp.
      When in doubt, say N.


  • Option: HOTPLUG_PCI_PCIE_POLL_EVENT_MODE
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Use polling mechanism for hot-plug events (for testing purpose)
    • depends on HOTPLUG_PCI_PCIE
      Say Y here if you want to use the polling mechanism for hot-plug events for early platform testing. When in doubt, say N.
