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.

Yesterday's Activity
- gitlab-ci: bump piglit checkout commit
Mesa - Timothy Arceri: Part-of: < - iris: Implement buffer-local memory barrier based on cache coherency matrix
Mesa - Francisco Jerez: This takes advantage of the previously introduced cache tracking infrastructure in order to define a multi-purpose barrier operation that allows the caller to order memory operations with respect to previous operations performed on the same buffer from any other cache domain. - iris: Add infrastructure to partition batch into sync boundaries
Mesa - Francisco Jerez: This introduces some minimalistic infrastructure which will be used in order to partition the batch into a series of sections, each one with a unique, monotonically-increasing sequence number. - iris: Add batch-local synchronization book-keeping to iris_bo
Mesa - Francisco Jerez: The purpose of this is to represent the cache coherency state of a buffer as a vector of integers (AKA seqnos), one for each incoherent caching domain of the GPU. - meson: add lcms2 dependency to cms-colord
Weston - Guillaume Champagne: cms-colord uses cms-helper functions which require lcms2. - radv: enable zero VRAM for Doom Eternal
Mesa - Samuel Pitoiset: That fixes some rendering issues. - intel/compiler: Extract control barriers from scoped barriers
Mesa - Boris Brezillon: Add a lowering pass extracting all control barriers embedded in scoped barriers into proper control barriers so we can get rid of the logic inserting control barriers when an SpvOpControlBarrier with WorkGroup scope is parsed in spirv_to_nir(). - pan/mdg: Allow f2u8 and friends thru
Mesa - Alyssa Rosenzweig: Now that we can handle destination sizes directly, this keeps us from needing to chew through so many conversions. - iris: Annotate all BO uses with domain and sequence number information
Mesa - Francisco Jerez: Probably the most annoying patch to review from the whole series --Mark every buffer object use as accessed through some caching domain with the sequence number of the current synchronization section of the batch. - iris: Introduce cache coherency matrix for batch-local memory ordering
Mesa - Francisco Jerez: This introduces a representation of the cache coherency status of the GPU at any point in the batch.
This Week's Activity
- ci: bare-metal: make it possible to use a script for serial
Mesa - Christian Gmeiner: Makes it possible to use e.g. - radv/aco: Always enable subgroup shuffle
Mesa - Timur Kristóf: It is now supported by both backends on all hw. - aco: Implement subgroup shuffle on GFX6-7.
Mesa - Timur Kristóf: GFX6 and GFX7 don't have the ds_bpermute (or permute) instruction, but we would like to support subgroup shuffle on these old GPUs. - ac/nir: support v2f16 derivatives
Mesa - Marek Olšák - glsl: handle int16 and uint16 types and add instructions for mediump
Mesa - Marek Olšák: v2: add more changes to ir_validate. - glsl: lower mediump integer types to int16 and uint16
Mesa - Marek Olšák - gallium: add shader caps INT16 and FP16_DERIVATIVES
Mesa - Marek Olšák - drm-backend: add --continue-without-input command line option to DRM-backend
Weston - Leandro Ribeiro: In the test suite we may want to run a DRM-backend test on a non-default seat, which may not have a input device associated. - pan/mdg: Enable out-of-order execution after texture ops
Mesa - Alyssa Rosenzweig: We don't make great use of it (due to the scheduler not being aware yet), but we can pack for it regardless and maybe pick up some win. - pan/mdg: Add pack_unorm_4x8 via 8-bit
Mesa - Alyssa Rosenzweig: More efficient than the 32-bit version in NIR.
