But 6 PCIe slots is still a good number :-) If you look at the cover letter of the PATCHv3, you'll see the output of lspci -vvv. It shows that I create one PCI-to-PCI bridge for each PCIe interface, regardless of whether the link is here or not. And for those where there is nothing behind the bridge, no address space reservation occurs, so I am not allocating address decoding windows for those unused PCIe interfaces.
