[PATCH 2/3] drm/dp_mst: Don't show connectors as connected before probing available PBN
...e in a moment), and I also played around with a couple
of different hubs and have a much better understanding of how this should work
now.
So: first off tl;dr available_pbn is absolutely not what we want in basically
any scenario, we actually want to use the full_pbn field that we get when
sending ENUM_PATH_RESOURCES. Second, full_pbn represents the _smallest_ bandwidth limitation encountered in the path between the root MSTB and each connected sink. Remember that there's technically a DisplayPort link trained between each branch device going down the topology, so that bandwidth limitation basically equates...
