Mesa 25.3 Lands SPIR-V Shader Replacement Support
Merged to Mesa 25.3-devel on Monday is SPIR-V shader replacement support as a new feature for helping Mesa's Vulkan drivers in testing and debugging issues.
The latest code added to Mesa allows dumping Vulkan (SPIR-V) shaders to an arbitrary directory for capturing. This documentation patch outlines all the details around the SPIR-V Shader Replacement support for Mesa Vulkan drivers and the new MESA_SPIRV_DUMP_PATH / MESA_SPIRV_READ_PATH environment variables. This merge goes into more details on the SPIR-V Shader Replacement support for the common Mesa code.
