[PATCH v2 0/5] drm/nouveau: Enable atomic modesetting by default

[Lyude Paul]

Nouveau is one of the very few modern hardware drivers in the kernel that
doesn't have atomic modesetting enabled by default, in part because when it
was originally written by Ben there wasn't much in the way of good atomic
modesetting clients to actually test things out with.

Nowadays however, atomic modesetting is very much the norm - and support in
userspace for non-atomic drivers is starting to bitrot a bit - leading to
its own set of issues. At the same time, many of those issues are fixed by
just turning on atomic in nouveau. Plus, I've been running nouveau with
atomic modesetting on by default for most of the machines I work on, and
I've already fixed quite a number of issues to the point where things seem
quite stable (excluding a single screen flashing bug on my desktop, which I
am not particularly convinced has anything to do with atomic modesetting).

This patch series enables atomic modesetting by default, at least for
NV50 and newer. NV04 is left unchanged, as atomic modesetting was never
implemented for it. This series also enforces leaving atomic modesetting
disabled on <NV50, and adds the value of nouveau.atomic to our kernel
debug output.
