GLSL/TGSI On-Disk Shader Cache Lands In Mesa For R600g/RadeonSI

Timothy Arceri who has been working on the Mesa on-disk shader cache for months and most recently began working for Valve on the AMD Linux driver stack has landed support in Mesa 17.1-devel for the GLSL/TGSI on-disk shader cache for the R600g and RadeonSI Gallium3D drivers.

With the latest Git activity today, the GLSL/TGSI on-disk shader cache has landed after being signed off by upstream AMD Linux developers. This will help in reducing load times for shader-heavy games and in making the Radeon gaming process more fluid for games that dynamically load OpenGL shaders when needed. Shadow of Mordor should be among the Linux games benefiting from this support.

This shader cache support makes use of previously-landed Mesa GLSL shader cache support and is also wired in through the Mesa state tracker so could be utilized too by other Gallium3D drivers that choose to.

I'll work on some benchmarks shortly to see if it ends up making much of a difference in our performance tests.
