Mesa 25.2.2 has been released as a bugfix update, featuring a variety of enhancements and fixes for its components and drivers. This update aims to improve performance and address several specific issues, including the addition of support for GL_EXT_shader_clock, corrections to texture page commitment verification, and fixes for pipeline barriers in Intel graphics.
- General Enhancements:
- Resolved support issues for GL_EXT_shader_clock.
- Improved verification for `glTexPageCommitmentARB` and `glTexturePageCommitmentEXT`.
- Ensured the consistent use of `base_serialized_nir` for drawing operations.
- Notable Contributions:
- Faith Ekstrand's contributions include enhancements to QMD queries and standardization of QMD versions.
- Josh Simmons addressed an out-of-bounds read issue, while Julia Zhang improved driver initialization processes.
- Robert Mader's work included improvements in sample handling within Gallium and fixing YCbCr format decoding issues.
- Intel (anv, brw): Resolved multiple issues related to pipeline management and uninitialized return values.
- AMD (radv, radeonsi): Fixed encoding issues and graphics pipeline hashing concerns.
- Nouveau: Silenced errors from unused methods and improved push data handling.
- Freedreno/Qualcomm: Addressed a viewport transformation bug.
- Panfrost/Vulkan (panvk): Fixed issues related to image memory binding and occlusion queries.
- Intel GFXStream: Prevented the use of outdated transitional APIs.
- Turnip (tu): Corrected handling for buffer binding commands.
