I really don't know about Frank and his plans. I didn't take over the DMA part, but that will eventually happen. For now I'm moving all register programming from GL driver to the DRM, but faking DMA at the same time. This will allow to prepare and debug everything very well making the DMA programming much more straightforward. The downside is that the DMA-emulation is very slow. This is taken a greate deal of changes. At this moment I'm trying to debug to make things work barely before I'll make a new branch: mach64-0-0-4-branch. But tommorrow I'll create it anyway, so that others can help on this work as well - I'm thinking on Leif, but Frank is welcome to join to and commit whatever he has done so far. I just don't see point to wait any further for doing this work, as it's the next logic step to take. >> But really nothing prevents someone to work on that subject since it >> can be made in parallel.

Since you don't have a 2nd machine, you must get used to control and add the debug output statements, as they'll be your debugger. About the reading give an overview to the FAQ to get the global picture, so that you'll know where to search when you need more detailed info. And at any time, you can ask any question to here that I'll make my best to answer them. > > Regards, > Felix > José Fonseca _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
