Hi, I saw that old NVIDIA EGLStream controller protocol is still used only in muffin.
Now recent driver already prefer and use linux-dmabuf, so the old nvidia protocol can be removed, or I'm wrong?

Hi. EGLStream controller is not replaced by linux-dmabuf, it's related to buffer management in driver, and recently Muffin is switching to use GBM by default. But Muffin doesn't contains many many Nvidia-related fixes that Mutter has (one of them #839 which is needed to properly implement drm-syncobj protocol which in turn is very important for Nvidia driver). So I prefer to leave EGLStream controller support in place, until Muffin get all necessary Nvidia pieces.

I think didn't check whether the Wayland (and protocol) versions in meson and d/control need to be updated. d/control doesn't seem to be updated.
Anyway I don't have time now to check all the Wayland protocols and functions currently used in Muffin to see what minimum versions need to be set.
