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! Signed-off-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
