Hrm... that's going to be tricky. For example the SR-IOV stuff will not
work for us, we are working on a different implementation, due to some
of "interesting" bridge constraints etc...
It would be nice to get more of the resource survey in common, our
original code was actually completely different and I reconciled it a
lot with x86 in the past few years, but I'm sure we can do better.
However there are still going to be corner cases....
Ben.
