[Mesa-dev] [PATCH 0/7] st/mesa: add shader image support

[Ilia Mirkin]

Please note that there is no complete nvc0 implementation backing this
(unlike the SSBO case), so I have not done more complete dEQP tests,
and a number of piglit tests fail.

Furthermore, there's the RGBA vs BGRA format issue that needs to be
resolved somehow. However I feel confident that this code is a good
start, and works as advertised. In all of the image failures I've
looked at, the TGSI always appeared correct.

Please have a look and let me know if this interface seems workable,
and what additional changes need to be done for this to be acceptable
in mesa.

Ilia Mirkin (7):
  gallium: make image views non-persistent objects
  gallium: add PIPE_SHADER_CAP_MAX_SHADER_IMAGES
  tgsi: show textual format representation
  st/mesa: add an image atom for shader images
  st/mesa: allow st_format.h to be included from C++ files
  st/mesa: convert GLSL image intrinsics into TGSI
  st/mesa: enable GL image extensions when backend supports them
