Somewhat less ugly patch for Mesa 7.8
When upgrading to mesa 7.8 I had to update my patch to get it to apply. 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.
