Release of Mesa 26.3, a free implementation of OpenGL and Vulkan

After three months of development, a release of the open-source implementation of the Vulkan, OpenGL, OpenGL ES, and OpenCL APIs — Mesa 26.3.0 — has been published. The first release of the Mesa 26.3.0 branch is experimental; a stable version 26.3.1 will be released following final code stabilization.

Mesa 26.3 features support for the Vulkan 1.4 graphics API in the ANV drivers for Intel GPUs, RADV for AMD GPUs, NVK for NVIDIA GPUs, HoneyKrisp (hk) for Apple GPUs, Turnip for Qualcomm GPUs, PanVK for ARM Mali GPUs, in the lavapipe (lvp) software rasterizer and in emulator mode (vn). The v3dv drivers (Broadcom VideoCore GPU for Raspberry Pi 4+) and dzn (Vulkan implementation on top of Direct3D 12) support Vulkan 1.0, the kk driver (KosmicKrisp, Vulkan on top of Metal) supports Vulkan 1.1, and the pvr driver (Imagination PowerVR GPU) supports Vulkan 1.2.

Mesa also provides full support for OpenGL 4.6 in the iris drivers (Intel Gen 8+ GPUs), radeonsi (AMD), Crocus (older Intel Gen4-Gen7.5 GPUs), AMD (r600), zink, llvmpipe, virgl (virtual GPU Virgil3D for QEMU/KVM), freedreno (Qualcomm Adreno), d3d12 (layer for running OpenGL on top of DirectX 12), and asahi (AGX GPU used in Apple M1 and M2 chips). OpenGL 4.5 support is available for NVIDIA GPUs (nvc0). OpenGL 3.3 support is present in the softpipe (software rasterizer) and nv50 (NVIDIA NV50) drivers. The panfrost (ARM Mali GPU) and v3d (Broadcom VideoCore GPU) drivers support OpenGL 3.1.

Key innovations:

• Rules for AI assistants have been added stating that Mesa fosters a community of people, so AI agents should not open pull requests or publish comments. For commits made by people but created using AI, it is required to explicitly indicate the tag 'Generated-by: LLM' or 'Assisted-by: LLM'. Separate restrictions on AI use have been introduced for the asahi, nouveau, panfrost, imagination, jay, and poly drivers.
