From: Thierry Reding <treding@xxxxxxxxxx> Hi Ben, here's a revised subset of the patches I had sent out a couple of weeks ago. I've reworked the BAR2 accesses in the way that you had suggested, which at least for GP10B turned out to be fairly trivial to do. I have not looked in detail at this for GV11B yet, but a cursory look showed that BAR2 is accessed in more places, so the equivalent for GV11B might be a bit more involved. Other than that, not a lot has changed since then. I've added a couple of precursory patches to add IOMMU helper dummies for the case where IOMMU is disabled (as suggested by Ben Dooks). Joerg, it'd be great if you could give an Acked-by on those two patches so that Ben can pick them both up into the Nouveau tree. Alternatively I can put them both into a stable branch and send a pull request to both of you. Or yet another alternative would be for Joerg to apply them now and Ben to wait for v5.5-rc1 until he picks up the rest. All of those work for me.
