displayport doesnt work with nouveau with GM200 (MMIO write FAULT)

Hi,

displayport doesnt work with nouveau (mesa 18.2.1-1, with GM200). I only get a blank/black screen.

dmesg:

Is there anything I can do/try from Arch-side or should I report a bug directly to freedesktop.org?

Re: displayport doesnt work with nouveau with GM200 (MMIO write FAULT)

Afaik GM200 support in nouveau is still highly experimental at best. But yes, likely a freedesktop bugreport if anything.
