[Freedreno] [PATCH 0/7] Enable pure integer texture sampling and rendering

[Ilia Mirkin]

This goes through and implements a bunch of the things needed to have actually
working integer texture sampling and rendering. With this, the piglit tests
largely pass.

This patch set has the unfortunate side-effect of exposing EXT_texture_integer
despite the fact that neither EXT_gpu_shader4 nor NV_gpu_shader4 are exposed
by mesa (nor GL3/GLSL130). I'll send a separate patch for mesa to only expose
this when the surrounding API can actually make use of it.

Ilia Mirkin (7):
  freedreno/a3xx: add format to emit info, use to set sint/uint flags
  freedreno/a3xx: remove blend clamp enables from gmem/clears
  freedreno/a3xx: disable blending for integer formats
  freedreno/a3xx: don't use half precision shaders for int/float32
  freedreno: allow each generation to hook into sampler view setting
  freedreno/a3xx: enable sampling from integer textures
  freedreno/a3xx: add missing integer formats and enable rendering
