This should be fixed in 4.12, which has acceleration support for GP10x cards.
Ah, nice thanks, I thought 4.11.x was including needed fixes (well, I only need nouveau support to try to make my HDMI output work with reverse PRIME). I guess I will need to wait a bit more then :) See you

Ignore that "failed to create kernel channel" error.
OK, I will then try to focus on why xorg server is crashing for me each time I try to effectively get the reverse prime to work ;) Best regards!
