CONFIG_PCIE_DPC: PCI Express Downstream Port Containment support

General informations

The Linux kernel configuration item CONFIG_PCIE_DPC has multiple definitions:

PCI Express Downstream Port Containment support found in drivers/pci/pcie/Kconfig

The configuration item CONFIG_PCIE_DPC:

• prompt: PCI Express Downstream Port Containment support
• type: bool
• depends on: CONFIG_PCIEPORTBUS && CONFIG_PCIEAER
• defined in drivers/pci/pcie/Kconfig
• found in Linux kernels: 4.18–4.20, 5.0–5.19, 6.0–6.12
• modules built: pcie-dpc

Help text

This enables PCI Express Downstream Port Containment (DPC) driver support. DPC events from Root and Downstream ports will be handled by the DPC driver. If your system doesn't have this capability or you do not want to use this feature, it is safe to answer N.
