[Mesa-dev] [PATCH 0/7] Anv: Border color fixes for Haswell

[Lionel Landwerlin]

Hi,

This is another attempt at fixing the border colors on Haswell. Patch 1 is
probably a genuine fix, the rest implements a workaround for the integer
formats.

The idea is the following, store the border colors and wrapping information
for all the samplers as well as some additional information about the
texture format last bound to a sampler into a UBO. When a shader tries to
access a sampler with integer format, do some bounds checking and load the
border color from the UBO if needed.

Thanks,

Lionel Landwerlin (7):
  anv: Fix border colors with normalized formats on gen7/gen75
  anv: sampler: store border color & wrapping modes on Gen7.5
  anv: descriptorSetLayout: allocate additional space for a hidden ubo
  anv: descriptorPool: allocate additional space for a hidden ubo
  anv: descriptorSet: allocate hidden ubo for border colors
  anv: descriptorSet: write sampler border colors on update
  anv: add nir pass to insert border color workaround
