No. First of all, the PCI bus driver will only allocate resources for direct children. It simply passes requests up the tree for grandchildren (this is how ISA devices behind a PCI-ISA bridge request resources). In this case, you will want to allocate resources for your BAR and your interrupt using bus_alloc_resource() during your attach routine. You can then either share the resources directly with your children by returning your resource values in your own bus_alloc_resource() method (see ppc(4) for an example of this) or subdivide your resource to make new resources (the easiest way to do this is probably to create a rman from your resource and then use rman_reserve_resource() to sub-allocate chunks of that to your children). For the interrupt resource you can just return your own resource pointer directly in your bus_alloc_resource() routine.

Ok, that makes things a bit clearer.
Thank you for your help!
