Intel's Mesa DRI Driver Now Supports Shader Subroutines

This week Mesa development is very exciting with OpenGL 4.0~4.1 support being reached and the open-source hardware drivers now just filling in their gaps. Intel's Mesa i965 DRI driver is getting ready to declare OpenGL 4.0 compliance.

David Airlie at Red Hat had filled in the last bits for ARB_shader_subroutine, which is needed for OpenGL 4.0, with the Intel DRI driver. He committed, "This just adds some missing pieces to nir/i965, it is lightly tested on my Haswell."

This just leaves the Intel driver to land its ARB_gpu_shader_fp64 and ARB_tessellation_shader patches for GL4 and ARB_vertex_attrib_64bit for OpenGL 4.1. Let's hope that this support can be squared away ahead of the branching for Mesa's next release in September.
