Just a suggestion but how about adding the header file to the Wiki and anyone who comes up with more info can throw it into it as well.. so everyone works from the same basic register sets...
Dave. so many cool things to do, not enough time :-)
Actually, I am in the process of opening a new project on SF just for R300 and similar development - this will go directly into CVS.
One of the tools (glxtest) has TCL program that converts command stream
into readable forms (by humans and C compiler) and it also autogenerates the register header.

Hi,
while I've had less success (read: hard locks and reboots) with the recently drmtest and r300_demo, I did use glxtest to find out registers of the R300.
Basically, what I did is run a small GL program, get the command buffer, make some small changes and rerun. Often, this results in only a small change in the command buffer (found using diff), which makes it possible to guess register addresses and constants. So while I haven't been able to crosstest my results by _sending_ commands using my new knowledge, I am pretty certain that they are mostly correct (as long as there is no explicit comment stating otherwise).
So far, I have found registers for alpha blending and testing among other things. I have also decoded most of the vertex program instruction set. However, I do not have the registers for vertex program *setup* yet. All I know is that both the program and its environment/parameters (whatever you want to call it) are uploaded via 0x2208.
All my findings are documented in the attached header file.
cu, Nicolai
