Key Enhancements and Fixes

This release incorporates numerous fixes and improvements across various components and drivers, including:

1. General Mesa & Core Functionality:
   • Support for GL_EXT_shader_clock has been fixed.
   • The level verification for glTexPageCommitmentARB and glTexturePageCommitmentEXT has been corrected.
   • Fixes have been applied to ensure that base_serialized_nir is always used for draws in mesa/st, and the build with PRINT_RELOCATE_SLOT in nir/opt_varyings.
   • Other notable contributions include:
     • Faith Ekstrand's work on stopping add_languages() calls in subprojects, adding a nak_qmd_size_B() query, allowing for variable-sized QMDs in nak/hw_runner, enabling larger QMDs in nvk, and standardizing QMD versions 4.0 and 5.0 to 384B.
     • Josh Simmons' fix of an out-of-bounds read in BITSET_EXTRACT within the util component.
     • Julia Zhang handled the driver initialization in OnSetup for the pps component.
     • Robert Mader's implementation of setting and counting all extra samplers in gallium, as well as fixing 10/12-bit SW decoder YCbCr formats in nir.
2. Driver-Specific Fixes:
   • Intel (anv, brw): Various fixes have been applied to address issues such as analysis dirtying with pulled constants, uninitialized return values, uniforms from opt_offsets, pipeline barriers with pre-rasterization stages, and more.
   • AMD (radv, radeonsi): Fixes have been made for H264 encode 8x8 transform when CABAC is disabled, HEVC encode cu_qp_delta issues, graphics pipeline hashing when no stages are compiled, and more.
   • Nouveau: Errors related to never-used methods in nak/nouveau have been silenced, and a fix has been applied for the nv_push Rust push_inline_data implementation in nouveau/headers.
   • Freedreno/Qualcomm: A missing line viewport transformation has been fixed.
   • Panfrost/Vulkan (panvk): Disjoint image memory binding has been fixed, and an occlusion query pointer fix has been revised.
   • Intel GFXStream: The guest driver is prevented from using a transitional LFS64 API.
   • Turnip (tu): Size handling for CmdBindTransformFeedbackBuffersEXT has been fixed.
3. Documentation & Release Management:
   • Eric Engestrom has added the SHA sum for the previous release, updated the .pick_status.json file, marked specific commits as denominated, and added release notes for 25.2.2.
   • Eric R. Smith has fixed an off-by-one error in MSRTT handling.
