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

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.

Today's Activity

libdrm: add drm syncobj create/destroy/import/export
libdrm - Dave Airlie: These ioctls are now in drm next so add the first set of libdrm APIs.

ac/nir: Make intrinsic_name buffer long enough
Mesa - James Legg: When using cmpswap on an image, it was being trunctated to lvm.amdgcn.image.atomic.cmpswa, with the coords type missing entirely.

i965/dri: Support R8G8B8A8 and R8G8B8X8 configs
Mesa - Chad Versace: The Android framework requires support for EGLConfigs with HAL_PIXEL_FORMAT_RGBX_8888 and HAL_PIXEL_FORMAT_RGBA_8888. Even though all RGBX formats are disabled on gen9 by brw_surface_formats.c, the new configs work correctly on Broxton thanks to _mesa_format_fallback_rgbx_to_rgba(). On GLX, this creates no new configs, and therefore breaks no existing apps.

mapi: Enable assembly language API acceleration for PPC64LE (V2)
Mesa - Ben Crocker: Implement assembly language API acceleration for PPC64LE, analogous to long-standing implementations for X86 and X86-64.

Yesterday's Activity

nir: add support for 64-bit in SmoothStep function
Mesa - Juan A. Suarez Romero: According to GLSL.std.450 spec, SmoothStep expects input to be a floating-point type, but it does not restrict the bitsize.

mesa: fix clip plane enable breakage
Mesa - Marek Olšák: Broken by:

radeon/vcn: enable h264 decode entension support
Mesa - Leo Liu

i965: Add a RGBX->RGBA fallback for glEGLImageTextureTarget2D()
Mesa - Chad Versace: This enables support for importing RGBX8888 EGLImage textures on Skylake. Chrome OS needs support for RGBX8888 EGLImage textures because because the Android framework produces HAL_PIXEL_FORMAT_RGBX8888 winsys surfaces, which the Chrome OS compositor consumes as dma_bufs.

This Week's Activity

mesa: add no error support to copyteximage()
Mesa - Timothy Arceri

blorp/clear: Add a binding-table-based CCS resolve function
Mesa - Nanley Chery: v2: - Do layered resolves.

anv/blorp: Add a surface-state-based CCS resolve function
Mesa - Nanley Chery: This will be used in the next patch.

etnaviv: add support for snorm textures
Mesa - Christian Gmeiner: Based on a patch from Wladimir J.

etnaviv: add R8G8 texture support
Mesa - Christian Gmeiner: Passes texwrap GL_ARB_texture_rg piglit (with faked full texture rg support).

etnaviv: add support for swizzled texture formats
Mesa - Christian Gmeiner: Passes all ext_texture_swizzle piglits.

r600/asm: add support for other GDS operations
Mesa - Dave Airlie: This adds support for the GDS operations needed to do atomic counters.

r600: add support for vertex fetches via texture cache
Mesa - Dave Airlie: On evergreen we can route vertex fetches via the texture cache, and this is required for some images support.

mesa/glthread: switch to u_queue and redesign the batch management
Mesa - Marek Olšák: This mirrors exactly how u_threaded_context works.

mesa/glthread: add glthread "perf" counters and pass them to gallium HUD
Mesa - Marek Olšák: for HUD integration in following commits.

This Month's Activity

st/xvmc: deal with drivers wanting different texture formats
Mesa - Ilia Mirkin: Previously, texture formats were being used unconditionally without checking.

dix: Remove extension aliases
X.Org Server - Adam Jackson: This appears to be essentially unused.

vc4: Allow VBOs to be mapped during execution
Mesa - Eric Anholt: There's no reason we can't -- the mappings we expose are basically equivalent to persistent/coherent, already.

radeonsi: update all resident texture descriptors when needed
Mesa - Samuel Pitoiset: To avoid useless DCC fetches when DCC is disabled, descriptors have to be updated in order to reflect this change.

intel: common: add flag to identify platforms by name
Mesa - Lionel Landwerlin: The perf infrastructure needs to identify specific platforms, not just generations.

intel: common: add number of thread per eu
Mesa - Lionel Landwerlin: This will be used by to normalize OA counters.

i965/gen4: Add support for single layer in alignment workaround
Mesa - Topi Pohjolainen: On gen < 6 one doesn't have level or layer specifiers available for render and depth targets.

radeonsi: add a workaround for inexact SNORM8 blitting again
Mesa - Marek Olšák: GFX9 is affected.

glsl: gl_Max{Vertex,Fragment}UniformComponents exist in all desktop GL versions
Mesa - Iago Toral Quiroga: The current implementation assumed that these were replaced in GLSL >= 4.10 by gl_Max{Vertex,Fragment}UniformVectors, however this is not true: both built-ins should be produced from GLSL 4.10 onwards.

svga: add new num-failed-allocations HUD query
Mesa - Brian Paul: This counter is incremented if we fail to allocate memory for
