Gallium3D Drivers Set To Receive OpenGL 4.3 AoA Support

MESA --
David Airlie has been putting out some ARB_arrays_of_arrays patches this weekend for Mesa that implement this OpenGL 4.3 extension for all Gallium3D drivers supporting GLSL 1.30.

The ARB_arrays_of_arrays support for core Mesa was originally crowd-funded work by developer Timothy Arceri. This "AoA" code finally landed in Mesa last year with initial support for the Intel driver.

Thanks to work by David Airlie, everything is getting squared away so that this OpenGL 4.3 extension can be enabled for all Gallium3D drivers supporting GLSL 1.30. The enablement comes via a set of five patches sent out on Sunday.

This extension is about providing support for multi-dimensional arrays / arrays of arrays. Once this code lands, ARB_compute_shader, ARB_framebuffer_no_attachments, ARB_internalformat_query2, ARB_robust_buffer_access_behavior, ARB_shader_image_size, and ARB_shader_storage_buffer_object (except Nouveau NVC0) are the extensions still need to land in mainline Mesa before there will be OpenGL 4.3 support amongst the Gallium3D drivers. Mesa 11.2 is branching soon and it's looking like OpenGL 4.2 will probably not even be reached in time for this next Mesa version, but hopefully we will get to OpenGL 4.2~4.3 by the summer.
