So that needs to be clarified in the spec (see the discussion on the workgroup, some people seem to disagree :) I'm happy with this approach however. It matches driver expectations and doesn't require changing the APIs. It will require some churn inside PciBusDxe to make it cope with the offsets but that's less of a problem as the overall APIs to drivers are unaffected and thus it's just a matter of me doing it :) Cheers, Ben. _______________________________________________ edk2-devel mailing list [email protected] https://lists.01.org/mailman/listinfo/edk2-devel
