[Mesa-dev] [PATCH 0/2] Implement INTEL_fragment_shader_ordering

[kevin.rogovin at intel.com]

From: Kevin Rogovin <kevin.rogovin at intel.com>

INTEL_fragment_shader_ordering provides the ability for shaders
to issue a call to gaurnantee memory write operation ordering
of overlapping pixels or samples. In contrast to
ARB_fragment_shader_interlock, INTEL_fragment_shader_ordering
instead of defining a critical region (which must be in main() and
under no flow control) provides a single function that acts like
a memory barrier that can be called under any control flow.

Kevin Rogovin (2):
  mesa: Add GL/GLSL plumbing for INTEL_fragment_shader_ordering.
  i965: Add INTEL_fragment_shader_ordering support.
