Nouveau - Jun 2017 - Quad buffering support with Opengl and recent cosumer cards

Hello, recent consumer NVidia cards added quad buffering support (I 
tested it with Direct3D and a Geforce 1070 without things like 3dvision 
or 3d tv play)

Are there currently plans to bring quad buffering support for 
stereoscopic rendering over hdmi 1.4 for those cards, or does support 
will need to wait several years?

Of course, it would be about Opengl and Linux.
