The Lima driver, a project aimed at providing an open source driver for ARM Mali-400 and Mali-200 GPUs, was introduced 4 years ago, and after some reverse engineering work, a Quake 3 demo was showcase later in 2013 with an intermediate version of the Lima drivers. However, the main developer (libv) eventually lost interest or lacked time to further work, and the latest commit was made in June 9, 2013. But another developer (oklas) committed some code to limadriver-ng just a few days ago.
But don’t get too excited, as the modifications are minor with some build fixes, some other Makefile modifications, and only one C file modified with 6 new lines of code. But maybe that’s just the beginning… We’ll see.
Mali-400 GPU is now rather old, so why would somebody work on this? One explanation could be C.H.I.P and Pine A64 boards are both based on Allwinner SoCs with a Mali-400 GPU, but a more likely explanation is that libv invited new developers on limadriver.org:
2015-12-20: this project looking for developers, if you’d like to try, come to our IRC #lima
So we’ll have to see how this all turns out, and if somebody is indeed motivated on working on the port. If so, C.H.I.P and Pine A64 boards, as well as other Mali-400 based platforms, could get open source GPU drivers.
