But if you implement all callbacks of the pci-bridge-emul.c for standard PCIe hotplug capability then you do not need this new HOTPLUG_PCI_PCIE_EMUL at all. Existing HOTPLUG_PCI_PCIE driver would work without any issue. I have already implemented DLLSC basics for pci-mvebu.c and pci-aardvark.c controller drivers, patches are on the mailing list. I can help implementing it in other PCIe controller driver.
