Late last year AMD had released R600/700 3D code
and in late January had then released R600 3D register documentation
to begin work on an open-source driver stack supporting the latest ATI Radeon GPUs with 3D acceleration. One of AMD's partners in this open-source work has been Novell, which wrote an open-source utility to begin sending 3D commands to the GPU in a very primitive form and to analyze the different operations. This utility is called r600_demo, which we explain in full detail here
The key author of r600_demo is Matthias Hopf
, which gave a talk at the FOSDEM X.Org meeting about the work being done on R600/700 3D acceleration. This talk is really geared for developers and those after a technical understanding of AMD's latest GPU architecture for 3D programming.
Matthias had also talked about RandR 1.3
