Alex,

First I'd like to look into the problem I am having, without AtomBIOS VGA monitor is at 1600x1050 instead of 1920x1200 (xrandr + logs say it is at 1920x1200, but it isn't).  With AtomBIOS DVI monitor is very flickerly, goes black for a second then back to X then black etc. etc.  I have raised a bug, but I do understand that there are lots of bugs to fix and lots of features to add and far too little time to do either.  Since I have done some lowlevel programming in the past I thought I might try and help.  I guess this is mode setting and from what I understand I can't fix the AtomBIOS case since the mode settings are from the BIOS.

In both the atom and non-atom cases, the bugs are likely in the driver. The atombios problems are most likely an ordering issue or a problem with the parameters passed to the command tables rather than a problem with the tables themselves.

Secondly, I'd like to look into UVD, however, it might be that Gallium3D provides this kind of acceleration, not 100% sure.

Acceleration related things like video decoding would be handled in mesa or a separate backend lib for the API you want to accelerate. We have not released any documentation yet for the UVD block, however, video decode can be accelerated using the 3D engine. Alex

Scott.

Thanks for the link, another question, should I be concentrating on the case when the driver is using AtomBIOS (Option "AtomBIOS" "True" in xorg) or without it ?

It depends what you are interested in working on. Using atom or not relates to mode setting, but is irrelevant for things like acceleration.

All,

I'd like to help in the development of this driver how do I get involved ?  Are there docs from AMD/ATI about the different cards and how to program them ?  how do I get hold of them ?

The asic documentation is linked from this page: http://wiki.x.org/wiki/DataSheets
