There's still one week until the work will be officially announced, but the open-source "Lima" open-source graphics driver project has surfaced. The Lima driver? This is going to be the open-source driver built for ARM's Mali graphics processors. Lima is what the project's being called for the story Phoronix exclusively broke last week, An Open-Source, Reverse-Engineered Mali GPU Driver.
Lima initially is about providing an open-source (OpenGL ES 2.0 supportive) user-space for ARM's Mali 200 and Mali 400 graphics processors, which is the embedded graphics processor being found in more mobile devices. The reverse-engineering and driver writing is being done by Luc Verhaegen and sponsored by Codethink.
The Lima code is to be pushed to this Gitorious project page. "Lima is a free software graphics driver for the ARM Mali GPUs. It aims to provide a free userspace, which will allow for increased flexibility and portability, and a lessened maintenance burden compared to ARM’s binary-only driver. Lima currently supports the Mali-200 and Mali-400 GPUs."
