==== TGSI ====
{{Main|Tungsten Graphics Shader Infrastructure}}
The Tungsten Graphics Shader Infrastructure (TGSI) was introduced in 2008 by Tungsten Graphics. All Gallium3D-style UMDs ingest TGSI.
NIR is now Main development area, so TGSI is only for older driver like r300g default infrastructure and will be deprecated in some years.

GLSL-To-TGSI code will be deleted in Mesa 22.2. Default is newer NIR-to-TGSI with GLSL-to-NIR for all native NIR drivers. Some older TGSI drivers are supported with this NIR Code path. Later NIR-To-TGSI will be deprecated for native NIR drivers only.<ref>{{cite web | url=https://www.phoronix.com/scan.php?page=news_item&px=Mesa-Stripping-GLSL-To-TGSI | title=Mesa Prepares to Drop Old GLSL-To-TGSI - Big Code Removal, Win for Performance & Fixes }}</ref>
