[Mesa-dev] [PATCH v2 00/17] i965 ARB_get_program_binary support

[Jordan Justen]

git://people.freedesktop.org/~jljusten/mesa i965-get-program-binary-v2

v2:
 * GL_MESA_program_binary_formats published in Khronos OpenGL-Registry
 * Drop compression. (Tim)

v1:
 * https://lists.freedesktop.org/archives/mesa-dev/2017-November/176095.html

This series adds i965 support for ARB_get_program_binary with one
supported format. We make use of the glsl program serialization
(introduced with shader cache) along with nir serialization. Later we
can add support for saving the gen binary program as well.
