[Mesa-dev] [PATCH v4 00/11] st/mesa: add shader buffer support

[Ilia Mirkin]

I believe I've addressed the various feedback people had. There's the
outstanding point of how to expose the atomic buffer bindings, but
this is a larger issue and largely tangential to the actual code
changed in this series.

No one has commented on my glsl_to_tgsi bits, which I sort of
expected. Unless I hear outcry to the contrary, I'm just going to push
those unreviewed once everything else is good -- nobody knows that
code particularly well, and I've run the dEQP tests, which leads me to
believe it's at least mostly good.

Ilia Mirkin (11):
  tgsi: add MEMBAR opcode to handle memoryBarrier* GLSL intrinsics
  glsl: always initialize image_* fields, copy them on interface init
  glsl: keep track of ssbo variable being accessed, add access params
  mesa: add PROGRAM_IMMEDIATE, PROGRAM_BUFFER
  st/mesa: add atomic counter support
  st/mesa: add support for SSBO binding and GLSL intrinsics
  st/mesa: use RESQ to find buffer size
  st/mesa: add support for memory barrier intrinsics
  st/mesa: add shader buffer barrier bit
  st/mesa: enable ARB_shader_storage_buffer_object when supported
  trace: add support for set_shader_buffers
