Hi Thomas, Basically, I agree with this patch as PciIoDevice->BusNumberRanges equals Configuration from PciResAlloc->StartBusEnumeration, and according to PI spec "Because the size of ACPI resource descriptors is not fixed, StartBusEnumeration() is responsible for allocating memory for the buffer Configuration".
But I hope Ruiyu can double confirm it. Since Ruiyu is taking leave for some days, could you wait?
