Basically, NVIDIA has come out and said that they don't want to be in the business of supporting window systems, they just want to be in the business of providing modesetting and direct rendering. They're proposing new things into EGL like the new EGLDevice abstraction and EGLStreams so that NVIDIA can tie less into Wayland and simply allow people to do cool stuff with their driver.
They're not going to support KMS immediately, as it's too simplistic for the full range of stuff that they would need to do (complicated modes, stereo support, etc.). The FOSS driver people are working on atomic modeset and atomic pageflip, which NVIDIA will investigate the API and see if it fits their needs.
They're also happy to support this stuff if we give them an API that ties into their driver and allows them to drop some of their code, but we first need to do that, with their feedback. The community is actively working on that.
