Android phones use Surface Flinger, which is a compositor that has nothing to do with either Wayland or X11. But we could say it’s kinda similar to Wayland in the fact that it’s composited and uses something similar to GBM and GEMM for managing buffers.
Android drivers don’t even use the same “semantics” as Linux drivers (android uses explicit sync, while Linux is implicit, but they are working on supporting explicit sync because Nvidia and because it’s better). It’s only in the last few years that you can use Linux drivers in android, plus some synchronization stuff.
Surface flinger code has some X11 code, I didn’t say it ran X11, I said it just had some of it’s base, GBM and GEMM have been only appeared in the new versions of Surface flinger.
Well it’s slightly harder to spot if it’s in a different position or orientation. (Or at least that is my assumption based on the limited number of “tests” like that one that I’ve seen.
There’s the Nvidia Shield tablet and some old Google Nexus that runs on tegra. Also if you are one of the unlucky People that bought a Windows RT tablet expecting it to run any program at all, you might have a tegra. Also the Nintendo Switch has one.
Fun fact: if I’m not mistaken, the Nexuses used nouveau.
Strangely topical for me. I wasted yesterday telling myself I was smart enough to make SwayWM on Wayland work well with my 1070. Should have trusted the warnings in the documentation; hubris cost me a weekend day!
