David Airlie http://lca2015.linux.org.au/schedule/... Displayport is a VESA standard for transporting video/audio/other data between devices, it is used on lots of laptop and monitors. The Displayport 1.2 standard introduced a new technology called multi-stream transport (MST), and a number of laptop dock manufacturers (Lenovo, Dell) started using this technology to provide the output ports on the dock. However nobody told the Linux community this was coming or at least nobody in the community noticed in time!
So armed with a dock and shiny Lenovo laptop provided by the Red Hat IT department, David descended into the murky world of MST. This talk is his tale. From the laptop docks with Intel graphics, he migrated to the world of 32" monitors with MST requirements and hubs. He diverged into looking at ATI support, and nagged nouveau team members into looking at nvidia support.
