Hi Chirag, As you're probably aware, the open source 3D graphics drivers are a bit behind on OpenGL functionality - we just reached OpenGL 3.3 support, while the latest is OpenGL 4.4. One of the challenges we face when trying to implement new features is that there isn't a good test suite. In order to know that our new driver code works, we first have to write a lot of Piglit tests, which slows down the process considerably. As Anuj mentioned, this usually means looking at OpenGL extension specifications, or new GLSL language versions, and writing tests for the new functionality. It's not extremely glamorous work, but it is very useful. Piglit tests are usually written in C, and are just simple OpenGL programs. Piglit provides a bunch of helpful functionality to make test writing easier (which is in tests/util). --Ken
