[Nouveau] [PATCH 00/44] drm/nouveau: display rework to support GSP-RM

[Ben Skeggs]

From: Ben Skeggs <bskeggs at redhat.com>

The primary issue being tackled here is that, for historical reasons (we
didn't know any better / couldn't make it work reliably otherwise), some
operations (SOR routing, DP link training) were performed during the 2nd
HW supervisor interrupt.

We don't have control of the display supervisor when running on top of
RM, so this needed to be untangled and fixed - which, is one of the main
aims of this patch series.

The ordering of this series is pretty important, so take care if/when
backporting patches from it.

Beyond that main goal, various other interfaces have been added or
extended to provide the information that RM will need for its version of
similar interfaces.
