CONFIG_PCIEPORTBUS: PCI Express Port Bus support

General informations

The Linux kernel configuration item CONFIG_PCIEPORTBUS has multiple definitions:

PCI Express Port Bus support found in drivers/pci/pcie/Kconfig

The configuration item CONFIG_PCIEPORTBUS:

• prompt: PCI Express Port Bus support
• type: bool
• depends on: CONFIG_USB4
• defined in drivers/pci/pcie/Kconfig
• found in Linux kernels: 3.12–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12

Help text

This enables PCI Express Port Bus support. Users can then enable support for Native Hot-Plug, Advanced Error Reporting, Power Management Events, and Downstream Port Containment.

PCI Express support found in drivers/pci/pcie/Kconfig

The configuration item CONFIG_PCIEPORTBUS:

• prompt: PCI Express support
• type: bool
• depends on: CONFIG_PCI
• defined in drivers/pci/pcie/Kconfig
• found in Linux kernels: 2.6.11–2.6.39, 3.0–3.11

Help text

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).
