so PCI_BUS_FLAGS_SUPPORTS_IO will never get set.
excellent catch. Unfortunately, I don't know how to make it
work with the reversed flag. The idea here was that the flag
propagates from parent to child. This makes sense for an
"it doesn't work" flag to be inherited from the child,
but not for an "it works" flag.
also would be better if we can add has_ioport in hostbridge instead.
like has_mem64 in https://patchwork.ozlabs.org/patch/500926/
and use
to_pci_host_bridge(bus->bridge)->has_ioport
to replace pci_root_has_io_resource()
Is there a function to get the root bus ? Otherwise I still need to
find the root bus first.
