[Mesa-dev] [PATCH 0/8] Implement GL_ARB_sample_shading on Intel hardware

[Anuj Phogat]

Patches listed below implement the GL_ARB_sample_shading extension
on Intel hardware >= gen6. I verified the implementation with a
number of piglit tests, currently under review on piglit mailing
list. Observed no piglit, gles3 CTS regressions with these patches
on SNB & IVB. 
These patches can also be found at my github branch:
https://github.com/aphogat/mesa.git branch: sample-shading-5

Anuj Phogat (8):
  mesa: Add infrastructure for GL_ARB_sample_shading
  mesa: Add new functions and enums required by GL_ARB_sample_shading
  mesa: Pass number of samples as a program state variable
  glsl: Add new builtins required by GL_ARB_sample_shading
  i965: Implement FS backend for ARB_sample_shading
  i965/gen6: Enable the features required for GL_ARB_sample_shading
  i965/gen7: Enable the features required for GL_ARB_sample_shading
  i965: Enable ARB_sample_shading on intel hardware >= gen6
