For those interested in DisplayPort MST support on Linux to support the specification's multi-stream transport ability, there is now a revised patch-set providing this support...

Acronyms I didn't know:

HPD: Hot Plug Detection
DPCD: Display Port Configuration Data (describes the receiver?s capabilities and stores the display?s connection status)

has anyone got this going yet?

I seen that there are some MST patches in the 3.16 kernel.. Am waiting for it to compile now, for the long shot of it working!

I can confirm that MST works on Fedora 22 with the following hardware:

- Dell M3800 Laptop
- Dell U2715H (plugged into the laptop's thunderbolt/mini-displayport)
- Dell U2415 (plugged into the MST output of the U2715H)

I haven't tried to use the nvidia card in this laptop, but the intel graphics work great.
