In both cases, the changes occur under the hiearchy: Scope (\_SB) { Scope (PCI0) { which leads me to believe that the change to the DSDT was needed due to the introduction of the ERST PCI device. And is explained in detail by Ani Sinha: I have convinced myself of the changes we see in the DSDT tables. On i440fx side, we are adding a non-hotpluggable pci device on slot 3. So the changes we see are basically replacing an empty hotpluggable slot on the pci root port with a non-hotplugggable device. On q35, bsel on pcie root bus is not set (its not hotpluggable bus), so the change basically adds the address enumeration for the device.
