Hi guys, for anyone still interested i this topic I have started a small scale campaign to do some Mesa development. In an effort to better understand if crowd sourcing Mesa development would work I have setup a small project on Indiegogo with the Goal of implementing the GL_KHR_debug extension (OpenGL 4.3). As a stretch goal I aiming to create a bit of a guide to get started with the basics of Mesa development based on my experience. Please feel free to ask me any questions, comment on my idea or in good old Phoronix fashion flame me for whatever your reasons my be.
To view my campaign just go to indiegogo and search for Mesa.
