The fact is that in the case of MMCONFIG overlap with PCI BARs, which
one takes priority is completely undefined. In the case of this Intel
chipset, clearly the PCI Express device connected to the northbridge had
higher decode priority than the MMCONFIG aperture.
can you relocate the MMCONFIG above RAM range? for example 512G...
On some chipsets that might be possible, however I think that on the
Intel ones it's not possible to move it above 4G. And in any case this
would require chipset-specific knowledge, which we would rather not have
to need.
