“While the RadeonHD developers have been busy working on Radeon
HD 3200 / 780 Series support and other features for this
open-source ATI R500/600+ driver, the DRM (Direct Rendering
Manager) support has been lagging behind. Earlier this month
Matthias Hopf was successful in getting DRM working on an RS690 GPU
and he has published RadeonHD DRM code into his personal
development tree, but no code has yet to reach master. Meanwhile,
as the xf86-video-ati driver is using AtomBIOS, they are able to
spend more time working on the 3D features and other areas and less
time ‘banging on registers’ or even waiting on register
documentation to arrive. David Airlie has been working on the R500
3D support along with Alex Deucher and Corbin Simpson. The trio has
been making some great headway towards open-source 3D goodness for
Radeon X1000 and HD 2000/3000 GPUs. Their most recent efforts have
focused around the R500 fragment program code and today they have
reached a monumental milestone…”
