I'm not sure who > originally was driving this (my google fu doesn't give me the mailing > list proposal ATM). It is getting a bit off the topic, but this it isn't really a problem with mesa. But rather that we have non-gallium closed src drivers from the GPU vendors in the ARM space, which only support GLES. And most/all of the desktop stuff packaged in fedora (in particular, gnome-shell) is requiring GL. The desktop gallium mesa drivers, and also the intel mesa driver, all seem to support both GL and GLES reasonably well.. >From a hw standpoint, while they may lack some features compared to desktop GPU, I think all the current mobile GPUs should support enough features in hardware to get gnome-shell running (possibly with some driver tricks, for example in freedreno I have to emulate quads with triangles). It wouldn't be enough for passing any GL compliance suite, but the requirements for gnome-shell are fairly basic.
