[SOLVED]Mesa-Git - OpenGL 4 not available

Hi everyone, i have hybrid graphics in my laptop computer. I have these graphic cards: Intel HD4000 and Radeon HD7670M. I'm using mesa-git from this repository:

[mesa-git]
Server = http://pkgbuild.com/~lcarlier/$repo/$arch

I'm using only mesa-git and xf86-video-ati-git packages. I'm using normal xf86-video-intel package from Arch repository, because git version causes many lags in display. To switch graphics i'm using PRIME method which is described here:
https://wiki.archlinux.org/index.php/PRIME

So, this is output from command DRI_PRIME=1 glxinfo | grep OpenGL

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD TURKS (DRM 2.43.0, LLVM 3.9.0)
OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.2.0-devel (git-b3340cd)
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 11.2.0-devel (git-b3340cd)
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.2.0-devel (git-b3340cd)
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00
OpenGL ES profile extensions:

As you can see OpenGL version is 3.0. I wonder why, because Radeon should have OpenGL 4 with latest mesa drivers. Steam reports OpenGL version 3.0 too. Intel card isn't support OpenGL4 on Linux, but Radeon should support it. How i can activate OpenGL4?

In normal mesa drivers from Arch repository i don't have OpenGL4 too. I had OpenGL 4 on AMD proprietary drivers, but i want to use open source drivers. Please excuse me mistakes, English isn't my first language.

Re: [SOLVED]Mesa-Git - OpenGL 4 not available

Not all cards supported by mesa r600g/radeonsi driver have OpenGL 4.x .

Your videocard uses the TURKS chipset from the Northern Islands family .

Read http://www.x.org/wiki/RadeonFeature/ , the OpenGL compatiblity line.
Check the foot note mentioned for NI chipsets.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: [SOLVED]Mesa-Git - OpenGL 4 not available

Yeah, you're right. Mesa doesn't support OpenGL4 on my graphics card. I haven't noticed this informations.

Thank you for help. So, 'problem' is solved now.
