Well, heres my source that they are planning to do this. Nvidia hasn’t exactly been loud about this, but judging by that, it will be easy for MIR to tap into the new EGL implementation even without any specific attention from Nvidia. I believe their goal is making something that will work regardless of what display server you’re using instead of being dependent on X11 like all former implementations.
It seems that we have had this non-x11 EGL support since version 346.xx (as stated in that article), I noticed I am running 346.xx myself and could confirm the presence of new egl files in /usr/lib/nvidia/, so as blackout24 said, I agree they’re probably cooking up something big for 347 or 350 (or whatever the hell their next version will be). The problem is that this new EGL implementation we’ve got doesn’t have proper KMS support yet (which is of course required for running wayland) judging by how long it’s been since we’ve had a beta driver.
I’m hoping we’ll see something in the next release judging by this. It’s the obvious next step to add in full kms and wayland support, Mir won’t be far behind if this is the case. But in the end, this is all speculation :(
