Another set of AMD RadeonSI Gallium3D driver improvements were committed on Wednesday for Mesa.

Marek Olšák spearheaded -- along with some contributions by David Airlie and others -- another batch of RadeonSI and Gallium3D improvements yesterday with some of the new enablements including:

- ARB_texture_gather and GLSL 4.00 Gather functions. All the related Piglit tests now pass and this is a step ahead for RadeonSI compared to R600g.

- ARB_texture_query_levels is now supported by all Gallium3D drivers that advertise GLSL 1.30 support.

- Passing ARB_conservative_depth parameters to the hardware.

- Implementing ARB_texture_query_lod, another OpenGL 4.0 extension not currently supported by R600g.

- Other common improvements to Gallium3D and the Mesa state tracker.

The current state of the Mesa/Gallium3D driver support for the OpenGL 4.0 specification (and other GL revisions) can be found via the Mesa GL3+ documentation in Git.
