there is something which happened almost unnoticed by the community.

SoC-side drivers have been open source by TI for a long time for OMAP3/4/5
and other SoC, but the SGX/PVR documentation has just been:

	http://web.archive.org/web/20170923050320/http://powervr.gnu.org.ve/doku.php

(it looks as if the original website went down end of september - you may
speculate about reasons yourself).

But I just found this morning:

	https://community.imgtec.com/developers/powervr/documentation/

This looks to be very important (dated 07 Apr 2017):

	http://cdn.imgtec.com/sdk-documentation/PowerVR+Instruction+Set+Reference.pdf

I haven't spent time to look through the other material, but it looks as
if IMG has become much more open!

Maybe this material is already sufficient to write an open source firmware
for the PVR and assembler/compiler for shaders but this is something for
3D/GPU experts (you know I am hardware expert and still struggle with Linux
kernels :).

BR,
Nikolaus
