The open-source Lima driver
project that has been working on a reverse-engineered ARM Mali Linux graphics driver is still advancing.
The latest progress on Lima is getting open-source generated shaders for running Quake 3: Arena. This still isn't done on an actual graphics driver but are pre-built shaders for running the dumped game demo through the Limare development tools.
More details on this new work can be found by Luc Verhaegen's blog post
The best news for end-users just wanting an open-source Mali driver that works is at the end of the post... "Now we really have covered all the basics, time to find out how Mesa will play with our plans :)"
