| H A D | pcie_pci_bridge.txt | 1 Generic PCI Express to PCI Bridge
6 PCIE-to-PCI bridge is a new method for legacy PCI
9 Previously Intel DMI-to-PCI bridge was used for this purpose.
12 PCIE-to-PCI bridge should now be used for any legacy PCI device usage
13 with PCI Express machine.
15 This generic PCIE-PCI bridge is a cross-platform device,
17 see 'PCIE-PCI bridge hot-plug' section),

27 Guest OSes require extra efforts to enable PCIE-PCI bridge hot-plug.
