PINE64

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 ).

I did some research and posted here : http://forum.pine64.org/showthread.php?t...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.

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.
