There are a few useful prerequisites for contributing to Mesa and being efficient: 1) Know OpenGL and GLSL Tutorials: http://ogldev.atspace.co.uk/ You need to know the API one way or another. Eventually, you want to switch to the official OpenGL, GLSL, and extension specifications as your primary source of information. 2) Know the graphics pipeline Articles: https://fgiesen.wordpress.com/2011/07/09/a-trip-through-the-graphics-pipeline-2011-index/ I was surprised about how accurately Z/Stencil optimizations were described in part 7. It seems pretty dense. Oh and BTW, it's about DX11, but I see that as an advantage. The hardware documentation uses DX11 naming conventions, so why not just get to use them now. 3) Know the Mesa code base Knowing the code and the overall architecture is 50% of success. This applies to any project. 4) Know the hardware registers and ISA There is open documentation, but it doesn't contain everything. In such case, the code is the documentation.
