- PnP/ACPI resource allocation *after* it, but before driver loading (which wll cause new resources to be allocated). This could be fs_initcall, or whatever (that's what things like "acpi_event_init" already do).
If we put the PNP system driver here, we can easily do a quirk that ignores PNP resources that overlap PCI resources.
No, you don't need any quirks: you just do an "insert_resource()" and ignore the error return. If the (bogus) PnP resource clashes with the (correct) hardware PCI resource, the insert will simply fail. No quirks needed.
But it's kind ofugly to have the ACPI PCI root driver early and other PNP drivers later because they're basically similar animals.
No they are not.
If one does just device enumeration, and the other does resource registrations, then they ARE NOT similar animals at all. Don't claim that they are.
