Phoronix: RadeonSI Gallium3D Is Now One Extension Away From OpenGL 4.4 Compliance

Landing over night in Mesa Git is support for the RadeonSI Gallium3D driver with the ARB_query_buffer_object extension. Now on Mesa Git that means there is just one extension away before this AMD GCN OpenGL driver supports the 4.4 specification...

Great improvment on numbers, 2D supertux2 goes sometimes to 20 fps

When amdgpu will? It's still 3.0 on polaris11 (RX 460).

AMDGPU already support OpenGL 4.3, if you have latest mesa-git.
instead on mesa 11.2 (Ubuntu 16.04) you have OpenGL 4.1

@twice, 4.1 here (limited by LLVM version, would be 4.3 otherwise, as noted by Dea1993):

Mesamatrix is greening up. Nice! Though r600 seems to fall a bit back (relatively seen).

If you look at the GL Core version level, it's probably higher than 3.0. Mesa currently has no plans to support higher compatibility profiles than what it already does. But the Core version should keep going up until it hits the latest GL release.

Yeah I've noticed that. I wonder if there's a hardware restriction? A lot of the "red spots" for r600 also apply to nv50, which to my knowledge has those red spots because the hardware is incompatible. Maybe I'm wrong though, I didn't really look into it that much.

Not really, at least GL 4.4 can be done with some pre-GCN cards, and if I recall correctly even GL4.5 can be supported. The r600 driver doesn't have many developers working on it though. I think airlied has some WIP branches for some extensions, but I'm guessing he's busy being distracted by radv.

you should be excited, its main developer is working on radv
