Ah, I was assuming this pcie-hisi-error.c driver was for the same device claimed by pcie-hisi.c. Error drivers like this will have some device-specific knowledge (e.g., which registers to dump), but I guess they'll always be used with the generic acpi/pci_root.c driver, right? It looks like this driver has little or nothing to do with the PCI core directly. It does include drivers/pci/pci.h, but I'm not sure it really needs it. Maybe drivers/pci/controller/ is the best place for it, but I'm not sure. It's a little confusing because it's not really like the other things there. There are some vaguely similar things in drivers/acpi/apei/ and drivers/acpi/nfit/. And of course there are .acpi_match_table uses all over the drivers/ tree. Maybe we need a new subdirectory under drivers/pci? drivers/pci/controller/apei/? Any thoughts, Rafael? Bjorn
