ATI R200 Documentation Coming Too
Phoronix: ATI R200 Documentation Coming Too
In the Phoronix Forums following Friday's release of the (NDA-free) ATI R300 3D register information, AMD's John Bridgman has confirmed that he is looking to release documentation going back to the ATI Radeon 8500 era graphics processors. Years ago ATI had released this R200 documentation to the open-source driver developers at the time, but it was encumbered by legal restrictions. John doesn't believe these R200 documents will be of any use to the xf86-video-ati developers for improving the Radeon 8500 to 9250 open-source support, but that it will help assist new open-source developers in beginning to understand graphics programming...
If I have to say, it appears that they're really pulling out all the stops here when it comes to the OSS effort.
Any hope for r128 docs?
Is there any hope of having r128 documentation released? Phoronix Forum member Svartalf mentioned that he has an NDA-ed version of RagePRO docs. Perhaps they can also be released?
I too would like to see the r128 docs released. I found copies of NDA'd version a long time ago. If I can find them, I would have to imagine that ATI could find them in their archives.

rr47003oemp.pdf - Rage Mobility M3 Register Reference Guide (OEM)
It will be great if they will release specifications for PowerPlay, as today support for PowerPlay on my mobility radeon with FOSS drivers is very limited.

still works fine.
Obviously the R600/R700 push is number one priority currently, but where do we stand on the release of R200 and Rage 128 docs?
Aren't the Rage 128 docs already out there?
Also, I believe most of the information in the docs has already been put to use in the drivers, so I'm not sure how much it would help for these models.
