New Savage patches

[Felix <fx...@gm...>]

Hi Savage testers,

I uploaded a new set of patches (*_20041114.diff) to
http://freedesktop.org/~fxkuehl/savage/. These patches work for
Savage3D-based cards only at this point. It will not show the expected
results on Savage4-based cards and will most likely lock up. You have
been warned.

My latest experiments with Savage4 showed that the same approach (using
vertex DMA for all rendering) won't work here. It will take major
changes to get good support for Savage4 and later-on for Savage2000.
Since this is likely to involve binary-incompatible interface changes I
don't want to commit anything to CVS yet. However, I won't be able to do
much work in the next two weeks, so here is the current state for people
to play with.

The patches are against CVS HEADs as of about 1 hour ago. Apply the
patches in the respective root directories of the DRM, Mesa and X.org
source trees. This time they should include all changes needed for
compiling. No hand-editing should be needed.

Features:
      * vertex DMA -> slight performance improvement
      * the ShadowStatus option in xorg.conf now also applies to 3D
        rendering
      * all access to the hardware is done by the kernel. This is the
        basis for a secure driver that can be included in X.org, Mesa
        and kernel releases.

It also fixes a couple of bugs. It has been very stable on my Savage IX
here as far as I tested it (quakeforge, quake2, q3demo, torcs, fgfs).
Neverball has some serious texture mapping problems. I'm not sure if
this is a new problem (didn't try with the CVS version of the driver on
Savage IX). I'm not aware of any (other) regressions.

Happy testing,
  Felix
