[Nouveau] [PATCH 1/4] drm/nouveau: dispnv50: Don't create MSTMs for eDP connectors
On the ThinkPad P71, we have one eDP connector exposed along with 5 DP
connectors, resulting in a total of 11 TMDS encoders. Since the GPU on
this system is also capable of MST, we create an additional 4 fake MST
encoders for each DP port. Unfortunately, we also do this for the eDP
port as well, resulting in:
1 eDP port: +1 TMDS encoder
+4 DPMST encoders
5 DP ports: +2 TMDS encoders
+4 DPMST encoders
*5 ports
== 35 encoders
Which breaks things, since DRM has a hard coded limit of 32 encoders.
So, fix this by not creating MSTMs for any eDP connectors. This brings
us down to 31 encoders, although we can do better.
This fixes driver probing for nouveau on the ThinkPad P71.

[Nouveau] [PATCH 2/4] drm/nouveau: dispnv50: Remove nv50_mstc_best_encoder()
When drm_connector_helper_funcs->atomic_best_encoder is defined,
->best_encoder is ignored both by the atomic modesetting helpers. That
being said, this hook is completely broken anyway - it always returns
the first msto for a given mstc, despite the fact it might already be in
use.
So, just get rid of it. We'll need this in a moment anyway, when we make
mstos per-head as opposed to per-connector.

[Nouveau] [PATCH 3/4] drm/nouveau: dispnv50: Use less encoders by making mstos per-head
Currently, for every single MST capable DRM connector we create a set of
fake encoders, one for each possible head. Unfortunately this ends up
being a huge waste of encoders. While this currently isn't causing us
any problems, it's extremely close to doing so.
The ThinkPad P71 is a good example of this. Originally when trying to
figure out why nouveau was failing to load on this laptop, I discovered
it was because nouveau was creating too many encoders. This ended up
being because we were mistakenly creating MST encoders for the eDP port,
however we are still extremely close to hitting the encoder limit on
this machine as it exposes 1 eDP port and 5 DP ports, resulting in 31
encoders.
So while this fix didn't end up being necessary to fix the P71, we still
need to implement this so that we avoid hitting the encoder limit for
valid display configurations in the event that some machine with more
connectors then this becomes available. Plus, we don't want to let good
code go to waste :)
So, use less encoders by only creating one MSTO per head. Then, attach
each new MSTC to each MSTO which corresponds to a head that it's parent
DP port is capable of using. This brings the number of encoders we
register on the ThinkPad P71 from 31, down to just 15. Yay!

[Nouveau] [PATCH 4/4] drm/nouveau: dispnv50: Report possible_crtcs incorrectly on mstos, for now
This commit is seperate from the previous one to make it easier to revert in the future. Basically, while working on making MSTOs per-head as opposed to per-head-per-connector I discovered these lovely issues: https://gitlab.freedesktop.org/xorg/xserver/merge_requests/277 https://gitlab.gnome.org/GNOME/mutter/issues/759 Note as well that Intel already has a temporary workaround for this in their kernel driver. So, unfortunately we need to follow suit to avoid causing a regression in userspace. Once these issues get fixed, this commit should be reverted.

When drm_connector_helper_funcs->atomic_best_encoder is defined,
->best_encoder is ignored by the atomic modesetting helpers. That being
said, this hook is completely broken anyway - it always returns the
first msto for a given mstc, despite the fact it might already be in

So, just get rid of it. We'll need this in a moment anyway, when we make
mstos per-head as opposed to per-connector.
