      Yes.
      Thanks. From this post it sounded like they only focused in EGL.

        Also, if you look at Nvidia's introductory post on the mailing list, it contains this:

        we also needed extended functionality for EGLStreams and EGLOutput consumers provided by following extensions:

        - EGL_NV_stream_attrib

        - EGL_EXT_stream_acquire_mode

        - EGL_NV_output_drm_flip_event


        I don't know about you, but two _vendor_ extensions don't exactly scream "system-agnostic" to me.
        they're NV because they prototyped and implemented them first. If they ever get adopted they're probably going to go EXT.
        I think nvidia has to also think about other OSes (rather than just linux), and my guess is that (and their driver
        being a binary blob) is why they proposed this.
        If they only needed to care about linux, i'm sure they'd have implemented mesa-compatible GBM a long time ago, their
        engineers aren't dumb or lazy.

          Hope AMD can do the same soon.

            I don't know, wikipedia seems to disagree: https://en.wikipedia.org/wiki/Mesa_%...fer_Management
            And I really mean I don't know, wikipedia can be wrong. I just have two contradicting statements here.

              It has a Vulkan section as well, but that doesn't mean Vulkan is Mesa-specific ...

                Though, honestly it doesn't matter (if I understand correctly what GBM is or not). The reality is whatever Nvidia has released does not work out of the box with Weston. Hopefully that will change.

                  Do what ? AFAIK Wayland/Weston has been running on AMD drivers for a long time now...

                    Yes it works with mesa. But the support for this methods is implemented in amdgpu-pro? Or the implementation for that is not related to mesa and OpenGL, and is implemented in the amdgpu kernel module? I don't know if I'm misunderstanding something... (Very good news if wayland works with amdgpu-pro!)

                      I thought the discussion here was about adding modesetting functions to EGL, which our drivers (all-open and hybrid/pro) don't need because they both support native mode-setting in the drm/driver IOCTLs.

                      My impression was that the pro driver exposed all of the required bits to run Weston but I'm not sure if there has been any testing, so it's a good question.
