[Mesa-dev] [PATCH 0/7] nvc0: various perf improvements for Elemental

[Samuel Pitoiset]

Hi,

This little series tries to improve performance with the Elemental
demo (Unreal) and I actually have +6% FPS on both Fermi/Kepler. It's
not THAT much, but few weeks ago I also improved that demo by +15%.
But this time I looked mostly into the draw path and the invalidation
between compute and 3d instead of writing compiler optimizations.

I didn't see any regressions with full piglit on GK110, but I will
launch a new one on Fermi.

Please review,
Thanks!

Samuel Pitoiset (7):
  nvc0: reduce the number of PUSH_SPACE in draw path
  nvc0: only update primitive restart for indexed draws
  nvc0: simplify draw parameters upload for vertex shaders
  nvc0: be smarter when invalidating shader caches
  nvc0: clean nve4_compute_validate_textures()
  nvc0: only invalidate currently bound tic/tsc
  nvc0: add support for PIPE_CAP_SURFACE_REINTERPRET_BLOCKS
