OK, I am glad to test them after you post them out. At least, the 'struct gen_pci' pointer can be put in driver data of the platform_device now, which may remove dependency on pci_sysdata in this driver. But ARCH's pcibios code still may access 'pci_sysdata', do you have patches or solution to handle this issue? Do you think it is doable to introduce a option(from module parameter, or device tree, ...) to let the driver and PCI core ignore/bypass all pcibios handling for the generic bus? If that is OK, it can provide an approach to reach the goal a bit easy. In reality, generic host controller should be only used by VM, and VM's firmware shouldn't be very complicated and I think the option can meet most of demands.
