[Mesa-dev] [PATCH 00/16] Enable OpenGLES 3.1 on Haswell

[Jordan Justen]

git://people.freedesktop.org/~jljusten/mesa hsw-es31-v1

Since gen7 doesn't support sampling from a stencil buffer, we copy the
stencil texture to an R8_UINT texture, and sample from it instead.

This allows us to enable ARB_stencil_texturing and OpenGLES 3.1 on
Haswell.

Ivy Bridge and Baytrail require additional (in progress) work to fix
some integer border color sampling issues.

Jordan Justen (16):
  main: Add MESA_VERBOSE=api support for glTexImage
  main: Add MESA_VERBOSE=api support for glClearStencil
  i965/hsw: Don't advertise more than 64 threads for compute shaders
  i965/hsw: Adjust uploading default color for stencil surfaces
  i965: Fix assert with multisampling and cubemaps
  i965/gen7: Add R8_UINT stencil miptree copy for sampling
  i965: Track that the stencil data was updated when clearing
  i965: Track that the stencil data was updated when rendering
  i965: Track that the stencil data was updated when using Tex*Image
  i965: Add function to copy a stencil miptree to an R8_UINT miptree
  i965/gen7: Copy stencil when sampling the stencil texture
  i965/gen7: Use R8_UINT stencil copy when sampling the stencil texture
  i965: Enable ARB_stencil_texturing for Haswell
  i965: Enable ARB_texture_stencil8 for Haswell
  i965: Enable OpenGLES 3.1 for Haswell
