Graphics
The Graphics channel is devoted to topics concerning Linux/BSD open-source graphics (GPU) hardware drivers, graphics rendering APIs, display servers, and related graphics/display projects.
Beignet
Beignet is an open-source OpenCL implementation for Intel graphics cores on Linux.
Cairo
Cairo is a vector graphics drawing API that offers multiple hardware and software-accelerated back-ends. Cairo is used by a variety of projects from X.Org to Mozilla and WebKit.
GLVND
The libglvnd project by NVIDIA is an attempt to create an OpenGL venture-neutral dispatch library for Linux systems. Advertised as the new Linux OpenGL ABI, GLVND is designed to make it easier for multiple GPU drivers to co-exist on the same system.
Mesa 3D Graphics Library
This sub-channel is devoted to everything Mesa, including Gallium3D drivers.
Pixman
Pixman is a pixel manipulation and rendering library.
POCL
POCL is the Portable Computing Language and most notably provides an open-source OpenCL library implementation.
Video Acceleration
Projects concerning video acceleration and video playback on graphics adapters are found within this sub-channel.

The X.Org Server projects and other X.Org projects are tracked via this sub-channel.
This Week's Activity
- lima/ppir: implement full liveness analysis for regalloc
Mesa - Erico Nunes: The existing liveness analysis in ppir still ultimately relies on a single continuous live_in and live_out range per register and was observed to be the bottleneck for register allocation on complicated examples with several control flow blocks. - radv: implement Vulkan 1.1 features and properties
Mesa - Samuel Pitoiset - radv: implement Vulkan 1.2 features and properties
Mesa - Samuel Pitoiset - radv: enable Vulkan 1.2
Mesa - Samuel Pitoiset: This bumps the Vulkan version to 1. - turnip: Pretend to support Vulkan 1.2
Mesa - Jason Ekstrand: It doesn't really support any Vulkan properly yet so why not claim 1. - anv: Implement the new core version feature queries
Mesa - Jason Ekstrand: Vulkan 1.2 introduces some new structures to get the properties and features of a device from extensions that were promoted to core in 1.1 and 1.2. - anv: Implement the new core version property queries
Mesa - Jason Ekstrand: Vulkan 1.2 introduces some new structures to get the properties and features of a device from extensions that were promoted to core in 1.1 and 1.2. - gitlab-ci: Stop using manual jobs for merge requests
Mesa - Michel Dänzer: They were causing trouble with Marge Bot: The project settings require that the pipeline succeeds before a merge request (MR) can be merged, otherwise Marge doesn't wait for the pipeline to succeed before merging an MR assigned to her. - radeonsi: make sure fmask expand is done if needed
Mesa - Pierre-Eric Pelloux-Prayer: Closes: - radv/gfx10: enable all CUs if NGG is never used
Mesa - Samuel Pitoiset: Ported from RadeonSI.
This Month's Activity
- meta: Add cleanup function for Bitmap
Mesa - Yevhenii Kolesnikov: Buffer object and temporary texture were never freed, causing memory leaks. - intel/nir: Add a memory barrier before barrier()
Mesa - Jason Ekstrand: Our barrier instruction does not implicitly do a memory fence but the GLSL barrier() intrinsic is supposed to. - tests/amdgpu: Proper format for "-l"
libdrm - Luben Tuikov: Proper format for command line option "-l", listing the supported and unsupported tests: - radeonsi: remove TGSI
Mesa - Marek Olšák - gitlab-ci: Switch LAVA jobs to use shared dEQP runner
Mesa - Tomeu Vizoso: Take one step towards sharing code between the LAVA and non-LAVA jobs, with the goals of reducing maintenance burden and use of computational resources. - panfrost: Implement sRGB blend shaders
Mesa - Alyssa Rosenzweig: We use the lowering in nir_format_convert. - panfrost: Support rendering to non-zero Z/S layers
Mesa - Alyssa Rosenzweig: Fixes abort in STK's shadow implementation. - anv: Only enable EWA LOD algorithm when doing anisotropic filtering
Mesa - Kenneth Graunke: Updated documentation renames "Anisotropic Algorithm" to "LOD Algorithm" and adds a note for Gen9+ saying "The EWA Algorithm should only be enabled for Anisotropic Filtering modes. - blorp: Stop whacking Z24 depth to BGRA8
Mesa - Jason Ekstrand: The shader code required to do this is int(sat(x) * UINT24_MAX) which isn't really worth all the effort to avoid. - gallium/tgsi_from_mesa: Add 'extern "C"' to be able to include from C++
Mesa - Gert Wollny: The r600/nir backend is in C++ and needs to include this file.
