There are good points on both sides; as a Linux user, I feel the effects of their proprietary drivers and uncooperative approach, while I can also appreciate that they've managed to work with the Gnome and KDE project to have some support under Wayland, and the contributions they've made to the
machine learning communities. Ad a whole, I do think that the former outweighs the latter, and loath the acquisition, but do think that the resources they're packing will bring ARM to new heights for the majority users.
That's because they implemented egl streams, nothing has changed majorly since then. There's been a lot of talk, but no action towards unification. The ball is entirely in Nvidia's court and they continue to work together on this.
The funny thing about GBM vs EGLStreams, though, based on everything I’ve read online, is that there’s broad agreement that EGLStreams is the technically superior approach - and that the reason it’s been rejected by the Linux graphics devs is GBM, while inferior, has broad hardware vendor support. Apparently very few GPU vendors outside the big 3 had decent EGl implementations.
That's not true. EGLStreams would be better suited to Nvidia's proprietary driver design, but it's technically inferior. This is the "broad agreement". No one but Nvidia wants EGLStreams, or we would have implemented it in other drivers.
