[Mesa-dev] [PATCH 0/5] First batch of gm45 clipping/interpolation fixes

[Olivier Galibert]

  Hi,

This is the first part of the fixes I've done to make my gm45 work
correctly w.r.t clipping and interpolation.  There's a fair chance
they work for everything gen 4/5, but I have no way to be sure.

[PATCH 1/5] intel gen4-5: fix GL_VERTEX_PROGRAM_TWO_SIDE.
[PATCH 2/5] intel gen4-5: Compute the interpolation status for every
[PATCH 3/5] intel gen4-5: Correctly setup the parameters in the sf.
[PATCH 4/5] intel gen4-5: Correctly handle flat vs. non-flat in the
[PATCH 5/5] intel gen4-5: Make noperspective clipping work.

After this batch every piglit interpolation test involving no clipping
or fixed clipping passes.  Vertex clipping clearly never worked
(VERT_RESULT_CLIP_VERTEX is not used, so...) and clipdistance isn't
implemented.  These will be the topic of the second batch, whenever it
exists.

Best,

  OG.
