Mesa Gets Two New OpenGL 4.x Support Patch Series

[a user]

Your glxinfo is too old and is only showing the compatibility profile. Newer glxinfo shows core profile as well.

interesting suggestion but this would not explain why the unigine demos all claim the very same OpenGL version and tell me missing geometric shaders:

OpenGL vendor:   Intel Open Source Technology Center
OpenGL renderer: Mesa DRI Intel(R) Haswell Desktop

Yeah, that's usually how things go. Still, with GL 3.3 finished (in terms of Mesa infrastructure), the more difficult things can be tackled with more firepower.

I do believe that the road from GL 3.3 to GL 4.4 is considerably (i.e. many times) easier than the transition from GL 2.1 to GL 3.3.

That's what I thaugth too. Seems to me that GL4.4 with be in Mesa sometime next year. However there's still the Nouveau/Radeon parts that need to be done. I'd gladdly help with Nouveau but I somewhat don't know where to start.

i would be happy to get opengl 3.2 with the current mesa 10 running on my haswell intel. somehow it is still showing opengl 3.0 with missing some improtant extentsions, like geometric shaders.

Not really.

Geometry shaders and tesselation shaders are hard parts.

But Intel OpenSource Team got bigger , and AMD team got bigger, and Nouveau team have a little bit more docs, and there is more contrib from 3rd partys. More man power == faster peace of development.

There is a third.

Probably the easier ones.

8 are done

Phoronix: Mesa Gets Two New OpenGL 4.x Support Patch Series

With Mesa 10.0 that will be released in a few weeks time there is finally OpenGL 3.2 and 3.3 support. But with Mesa still being several years and revisions behind the latest Khronos Group specification, it's still a matter of implementing a lot of new GL4 functionality. Fortunately, there's many developers devoted to this task and on Tuesday there were patches for two new GL extensions...

If I'm not mistaken, both extensions are for GL 4.3, not 4.2.

It's nice to see OpenGL 4 support improving. From 14 items needed for OpenGL 4.0, 8 are done, 2 were started, and 4 are still to tackle.
