Intel's Mesa Driver Now Officially Exposes OpenGL 4.3

[chrisr]

Brilliant example of why such overrides need to be limited per-app

Happy to oblige...

[nanonyme]

Oops! I remember now... I think I might have set "MESA_GL_VERSION_OVERRIDE=3.3COMPAT" so that World of Warcraft will run...
(WoW crashes if something in OpenGL >= 3.2 isn't available in the core profile).

You must have overrides set somewhere. Your core profile mask says "compatibility profile", and your non-core info says OpenGL 3.3 and GLSL 4.30, also with a compatibility profile mask. But this is impossible, mesa doesn't support compatibility profiles. So the core profile mask should say "core profile", and the non-core info should say OpenGL 3.0 and GLSL 1.3 and no profile mask.

So yeah, check for overrides.

The only thing that comes to mind is --enable-texture-float

Hmm, that's not it :-(

autogen.sh --prefix=$HOME/Programs/local-mesa --libdir=$HOME/Programs/local-mesa/lib64 --with-dri-drivers=i965 --with-gallium-drivers= --enable-driglx-direct --enable-glx-tls --enable-texture-float --with-egl-platforms=drm,x11

Does the fp64 support need anything special?

The only thing that comes to mind is --enable-texture-float

I've tried building Mesa from Git for my gen8 Broadwell laptop, but although I'm seeing GLSL 4.3 I'm still only seeing Open GL 3.3. By the looks of things, none of the fp64 functions are being advertised. I'm guessing that the fp64 functionality isn't being built, although I can't see anything obviously missing in the configure output. Does the fp64 support need anything special?

And why not ? Its the principle of democracy.

Open source is not about democracy. For unpaid developers it's mostly about "what interests me most" and for paid developers it's mostly "what's most interesting to my company" that decides what gets done first.

The opengl 4.3 (4.5) doesn't matter much as intel is not for games and is very slow, is for internet browsing at most,

IMO 4.3 matters more on newer chips that are able to run low to medium graphics intensive games. In this particular case though it looks like the decision was simply made because the newer generations have a different achitecture in that area which makes an implementation easier/more elegant.

the point is disinformation of this article.

I don't see disinformation in this case. Not even in the headline. Only people unfamiliar with both Mesa and Phoronix could misinterpret it to mean "all done". None of the platforms that enabled 4.3 before Intel have support for all chips that are 4.3 capable. If anything, the developers enabling of GL 4.3 could be called misleading, as the drivers failed 4.3 tests in hundrets of cases. Still, developers enabled it and are now very active deciding which tests matter and getting the important and interesting ones fixed fist.

If you use lowest settings you can often get playable framerates with 720p or more - even with Haswell. It's not optimal but you can compare it to GT 630. With OpenGL 4.3 support you should need less overrides to start the games at least for Broadwell/Skylake. It's not made for pure gamers but certainly enough for casual players. Source engine games and older UE 2.5/3 games often work fine.
