Description

For quite a while, MST doesn't work stably. As DisplayPort version 2.0 having MST as the default transmission method, MST is no longer just a specific scenario. Thus, we must have our MST support much more stable and robust than before.

Besides the requirements from new technique, it's also a reasonable demand for laptop user to use multiple external disaplays. As the trend for laptop nowadays is having less output ports, USB Type-C is embraced by the industry which not only can transmit data but also video streams. User can leverage MST via type-c to send out video streams for the requirement of multiple external monitors.

AMD has spended lots of effort recently on solving MST relevant issues and pushed to support DP2.0 128/132b encoding. At the same time, we also address dsc over mst relevant issues to have scenario of transmitting high resolution streams by MST more solid. Thanks to the help from many contributors, we now have MST into better stabilized status.
