Lima is an open source graphics driver which supports Mali Utgard (Mali-4xx) embedded GPUs from ARM.
It’s a reverse-engineered, community-developed driver.
At XDC 2019 there was a presentation about Lima, which happened not long after its initial inclusion in upstream.
At that time, it was still missing some important features to be a complete driver.
Most of those have been addressed since then and the situation now is notably more stable.
This talk aims to provide a status update on Lima, a review of the more relevant recent work on it, and some possible paths going forward.
