[PATCH v2 0/9] drm/nouveau: Various fixes for GP10B

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Thierry
