Ah sorry, I meant to look at your email in more details and respond but
it fell through the cracks.
I'm happy to have a look at your work and see how it applies to me, you
can see my powernv code which also supports translation for devices
behind bridges here (but doesn't do as much caching as q35 does):
https://github.com/ozbenh/qemu/commit/4e0ed1002f98fd97aa7ca3a48c74933d0343dd42
Which depends on:
https://github.com/ozbenh/qemu/commit/facedeba8811985ca20ac3dbad5d07e1a10ea9b2
(Which I think Michael merged recently, I haven't checked).
Cheers,
Ben.
