I’ve written some other posts on Wayland recently, and it’s time for another one! Feel free to skip it it you aren’t interested in a discussion of Wayland and platforms. Many may …
All of Wayland is based on EGL. What you are referring to are EGLStreams vs GBM which are both libraries using EGL. Nvidia drivers now support GBM for all supported GPUs via a support library that comes with the driver (libnvidia-egl-gbm https://download.nvidia.com/XFree86/Linux-x86_64/510.39.01/README/gbm.html). There should be no difference in the GPU generation used.
