I think we have similar goals here. I'm doing this to hopefully make reverse engineering a bit easier, and also to improve my knowledge of Radeon and R300. I haven't yet tried my tool on R500 or above because I don't have an R500 card yet... I'll probably end up waiting for the work that Jerome Glisse et al are doing on R500 to become public. I think my tool should work there, too. > I just started reading the X code about 6 months ago, and the learning > curve has been steep.

I'm not an expert, but I can do my best. :) I'm sure that I could get some of the more experienced people to look over it, too. I guess this should probably be done on the Freedesktop Wiki. I could help on the ring buffer and indirect buffer packet format; I think I have a pretty good handle on this now. I intend to look into the vert/frag prog stuff, too, but I haven't done this yet. > > Cheers, > --Phil > > Example: > ./bitfield ati_regs.example I think that rules-ng is a better solution for me anyway. You can read about it at http://nouveau.cvs.sourceforge.net/nouveau/rules-ng/. I just have to integrate it into my tool. Pekka Paalanen already modified mmio-parse to add support for rules-ng, so I'll probably look at this for ideas. By the way, you should probably CC dri-devel too. I'm forwarding my replies dri-devel but you're just sending your emails directly to me. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
