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.

Wayland and its related components are tracked here.

X.Org

The X.Org Server projects and other X.Org projects are tracked via this sub-channel.

This Week's Activity

freedreno/a6xx: Turn on texture tiling by default
Mesa - Kristian H. Kristensen: The color swap isn't available for tiled formats and it's not needed either.

anv: Implement VK_EXT_conditional_rendering for gen 7.5+
Mesa - Danylo Piliaiev: Conditional rendering affects next functions:- vkCmdDraw, vkCmdDrawIndexed, vkCmdDrawIndirect, vkCmdDrawIndexedIndirect- vkCmdDrawIndirectCountKHR, vkCmdDrawIndexedIndirectCountKHR- vkCmdDispatch, vkCmdDispatchIndirect, vkCmdDispatchBase- vkCmdClearAttachments

intel/fs: Don't touch accumulator destination while applying regioning alignment rule
Mesa - Jason Ekstrand: In some shaders, you can end up with a stride in the source of a SHADER_OPCODE_MULH.

anv/allocator: Add support for non-userptr
Mesa - Rafael Antognolli: If softpin is supported, create new BOs for the required size and add the respective BO maps.

anv/allocator: Enable snooping on block pool and anv_bo_pool BOs
Mesa - Rafael Antognolli: We are not going to use userptr for anv block pool BOs anymore.

anv/allocator: Add padding information
Mesa - Rafael Antognolli: It's possible that we still have some space left in the block pool, but we try to allocate a state larger than that state.

anv/allocator: Rework chunk return to the state pool
Mesa - Rafael Antognolli: This commit tries to rework the code that split and returns chunks back to the state pool, while still keeping the same logic. The original code would get a chunk larger than we need and split it into pool->block_size.

anv: Split code to add BO dependencies to execbuf
Mesa - Rafael Antognolli: This part of the anv_execbuf_add_bo() code is totally independent of the BO being added.

anv/allocator: Add support for a list of BOs in block pool
Mesa - Rafael Antognolli: So far we use only one BO (the last one created) in the block pool.

anv/allocator: Add getter for anv_block_pool
Mesa - Rafael Antognolli: We will need the anv_block_pool_map to find the map relative to some BO that is not at the start of the block pool.

This Month's Activity

nir/gcm: Support deref instructions
Mesa - Jason Ekstrand: Even though no one's been brave enough to ever use this pass, I like to keep it functionally working.

spirv: Emit switch conditions on-the-fly
Mesa - Jason Ekstrand: Instead of emitting all of the conditions for the cases of a switch statement up-front, emit them on-the-fly as we emit the code for each case.

glsl/nir: keep bool types when native_integers=false
Mesa - Jonathan Marek: With the new handling of bool types, the conversion to float in glsl_to_nir should not apply to bool types anymore.

blorp: Add blorp_get_surface_address to the driver interface
Mesa - Kenneth Graunke: Currently, BLORP expects drivers to provide two functions for dealing with buffers: blorp_emit_reloc and blorp_surface_reloc.

glsl: Make invariant outputs in ES fragment shader not to cause error
Mesa - Danylo Piliaiev: In all GLSL ES versions output variables in fragment shader are allowed to be invariant.

anv/pipeline_cache: Add support for caching NIR
Mesa - Jason Ekstrand

anv/pipeline: Cache the pre-lowered NIR
Mesa - Jason Ekstrand: This adds a second level of caching for the pre-lowered NIR that's only based off of the shader module, entrypoint and specialization constants.

i965: Compile fp64 funcs only if we do not have 64-bit hardware support
Mesa - Matt Turner: Brown bag fix.

radv: enable variable pointers
Mesa - Samuel Pitoiset: The Vulkan spec 1.1.97 says: "variablePointers specifies whether the implementation supports the SPIR-V VariablePointers capability.

llvmpipe: Always return some fence in flush (v2)
Mesa - Tomasz Figa: If there is no last fence, due to no rendering happening yet, just create a new signaled fence and return it, to match the expectations of the EGL sync fence API. Fixes random "Could not create sync fence 0x3003" assertion failures from Skia on Android, coming from the following code:

Recent Releases

vulkan/utils: s/VERSION/PACKAGE_VERSION/
Mesa - Eric Engestrom: Everything else uses PACKAGE_VERSION, so let's be consistent, and

build: stop defining unused VERSION
Mesa - Eric Engestrom: Scons and autotools don't define it, and as of last commit nothing uses it.
