I took the opportunity to see if I could clean up the patch while I was at it. Essentially I tried to find what current code was the equivalent to the old code my patch re-introduced, and modify that instead. The new patch is still no beauty, but much better than the old one and now weights at a somewhat more modest 372 lines (removing 97 lines and adding 77 lines) Trying to analyse the changes I find three major ones, as well as some minor ones following from those, but as I'm no expert on Mesa I don't fully understand what impact they have, other than what I see on screen (Sauerbraten starting to work). 1) With the patch applied r700TryDrawPrims is called as a first stage of r600_pipeline instead of being called through the vbo_context(ctx)->draw_prims callback from the other stages. 2) In several places the patch replaces use of context->stream_desc with use of context->radeon.tcl.aos. 3) After doing the other changes, r700RunRenderPrimitiveImmediate have to use data from vb->Elts when calling R600_OUT_BATCH() or the graphic cards borks and requires a restart to output anything. I hope this work will help someone more knowledgeable to figure out how to fix the problem properly. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
