Hi, A repost of the current state of the displayport MST support for i915, mainly targetted the Lenovo docks.
Major changes since last posting: add a path blob property for userspace to use to track topology provide reference counting, locking and lookups for branch and port structs. some DocBook! fix i915 problems with DPMS - ordering of link bring up. aux channel locking - this should be pushed down I think into the aux helpers, TODO: fbcon support: fix non 4 lane 5.4Ghz. fix more of state checker harder. Dave.
