Radeonsi card stuck at software rendering

[pstn]

I think I misconfigured my system but can't find the cause.
My OpenGL is stuck at software

$glxinfo | grep OpenGL
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD PITCAIRN (DRM 2.43.0, LLVM 3.6.2)
OpenGL version string: 2.1 Mesa 11.0.8
OpenGL shading language version string: 1.30

X.log
Full config

Any help is appreciated.

Why do you believe it does rendering in SW? The X.log seems to me like it uses the usual HW rendering.

The OpenGL version is just 2.1 it should be > 3 for radeonsi on mesa 11.0.8. Additionally I think that the vendor string is X.Org for SW rendering, isn't it?

I believe it doesn't do SW rendering. After reading a gentoo comment, I think it shows a lower version because texture floats are disabled. That's so by default because of some patent issues.

You can override the settings by packageOverrides, e.g. as in https://github.com/ttuegel/nixos-config/blob/fc382dcd19e7f2ed2e34157de2c85671138b6665/overrides/mesa_drivers.nix but instead of llvmPackages = ... you put enableTextureFloats = true;.

SW rendering looks more like this:

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)
OpenGL version string: 2.1 Mesa 8.0.1
OpenGL shading language version string: 1.20

Thanks. I was able to successfully build mesa with TextureFloats and have a more recent OpenGL version now.
