Had a discussion with RH folks, summary follows:
1. To align with the current spec description pointed by Jonathan, we first do
a separate object instance per GI node as suggested by Jonathan. i.e.
a acpi-generic-initiator would only link one node to the device. To
associate a set of nodes, those number of object instances should be
created.
2. In parallel, we work to get the spec updated. After the update, we switch
to the current implementation to link a PCI device with a set of NUMA
nodes.
Alex/Jonathan, does this sound fine?
