I think the problem here is that the PCI BAR is bigger and spans the region reported by ACPI:
Ok, then it doesn't help that it's not busy.
In that case, the only real fix is to simply do the ACPI reservations *after* PCI probing. Which is what it should have done to begin with.
We can easily add more BIOSes to the PNP quirk.
No. Don't add quirks just because the basic ordering is shit.
I really don't want to use the earlier quirk that scanned PCI devices from a PNP quirk. I think that's just wrong because PNP (which conceptually includes ACPI) is what tells us about PCI root bridges.
So? Do the bridge listing separately from resource marking. Why tie the two together? They have absolutely *nothing* to do with each other.
The fact is, scanning devices should happen first. And AFTER the device tree is scanned, we can then safely add all the special resources that don't show up as normal devices.
