Allwinner Mali Information? - KPhillisJr - 01-13-2016 I figured I would start this thread to help gather information about the 3d engine within allwinner devices. I currently know that the latest arm driver release to support the Utgard Micro-architecture is r6p0-01rel0. This driver was released around November 10, 2015. The Mali versions that have possible support for this version are as follows... Mali-200 Mali-300 Mali-400 MP - This is what is in the Allwinner chips. Mali-450 MP Also, That said here is a short list of the Open source parts for this driver... Open Source Mali Utgard GPU Linux Kernel Drivers - kernel drivers. Open Source Mali GPUs UMP User Space Drivers Source Code - libump Open Source Mali GPUs Linux EXA/DRI2 and X11 Display Drivers - Xorg drivers Open Source Mali GPUs Android Gralloc Module - This is the open source portion of android drivers. Now all that is really needed would be to get the user space portions that is compatible with this driver release. I believe the driver that is included is about 4 years old ( r3p2-01rel2 ). RE: Allwinner Mali Information? - hlide - 01-13-2016 I did some research and posted here : http://forum.pine64.org/showthread.php?tid=85&pid=495#pid495 I didn't give the links to download them directly as I don't know whether I can post them here. EDIT: it seems the sources can be retrieved at their websites now unlike at the time I tried. RE: Allwinner Mali Information? - taros - 01-14-2016 There are three solutions for the Mali GPU (by ARM Holdings, not Allwinner). One, write a traditional accelerated graphics driver for Xorg (Xorg is used by almost all Linux distributions nowdays). Two, make an accelerated graphics driver for Wayland and/or Mir (Unity 8). Three, make a somewhat accelerated graphics driver for Xorg using fbturbo (https://github.com/ssvb/xf86-video-fbturbo). The third solution should be the easiest. I think the author of fbturbot (ssvb) is on this forum and can describe what work is missing for the Pine64. It is good to have xf86-video-fbturbo while working on the other solutions. The second solution requires less work than the first.
