Heh, no kidding ...
num_buses =3D pci_mmcfg_config[i].end_bus_number -
pci_mmcfg_config[i].start_bus_number + 1;
res->start =3D pci_mmcfg_config[i].base_address;
res->end =3D res->start + (num_buses << 20) - 1;
res->flags =3D IORESOURCE_MEM | IORESOURCE_BUSY;
insert_resource(&iomem_resource, res);
So if we have 256 busses assigned, then we request 256MB and, well,
there's no room for anyone else. This code was added by Andi in commit
de09bddb9d6f96785be470c832b881e6d72d589f
Hopefully he'll have a good idea how to restrict it. Given your "working"
resource map, it seems like it should be limited to 16MB (and thus 16 busse=
s).
But how to figure that out?
