Re: [Xen-devel] [v5][PATCH 0/5] xen: add Intel IGD passthrough support

OK, so how about doing this: either for the ISA
bridge, or for the VGA card itself:

    set subsystem vendor id to PCI_VENDOR_ID_XEN,
    set subsystem device id to PCH device id

That would work, but the same problem would then arise for the MCH. The driver there is banging at random places in the configuration space.

This is why I asked for a solution that is future-proof, and since you can make one that works for both MCH and PCH it is nice to do the work just once.
