Can I force Intel GM45 (OpenGL 2.1 / Mesa 13.0.5) with Gallium/LLVMpipe to OpenGL 3.2+ ?

[Jakub Lach]

Thanks to https://www.mesa3d.org/envvars.html it looks like
only LIBGL_ALWAYS_SOFTWARE=1 was needed. Though default
version is OpenGL 3.0 and rest depends on luck with overriding 
it.

<...>

OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.9, 128 bits)
OpenGL version string: 3.0 Mesa 13.0.5
OpenGL shading language version string: 1.30

<...>

Performance (as in fps) is about 30-60% of Intel GM45.
