Cover letter [PATCH v3 0/9] drm/nouveau: Various fixes for GP10B

From: Thierry Reding <[email protected]>

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 has given an Acked-by on the first two patches, so I think it'd be easiest if you picked those up into the Nouveau tree because of the build dependency of subsequent patches on them.

Thierry
