Bertrand, can you share `lspci -t` output, and also `lspci -vvs 80:00.0` ? Having read this

I think I somewhat understand what your machine is showing here.
Yes, my PCH is a Intel 800 Series WM880.
The CPU itself has integrated PCI host bridge, and then there's a further hostbridge provided by the 800 series chipset
In sysfs on your machine do you see multiple dir entries at
/sys/devices/pciNNNN.NN
??? If so, that's how we can identify the root complexes, regardless of the unexpectedly missing host bridge at 0000:80:00.0
Yes I have /sys/devices/pci0000:00 and /sys/devices/pci0000:80. Bertrand
