Other Activity This Week
- iris: Update fast clear colors on Gen9 with direct immediate writes
Kenneth Graunke: Gen11 stores the fast clear color in an "indirect clear buffer", as a packed pixel value. - glx: Make __glXGetDrawableAttribute return true sometimes
Adam Jackson: Right now it always returns zero, but as of: commit a48a6b8a400e6e92961cf7b7b4c287e8e9875f39 Author: Adam Jackson Date: Tue Nov 14 15:13:05 2017 -0500 glx: Prepare driFetchDrawable for no-config contexts We were hoping it would return true if the drawable could actually be looked up. - scons: define MESA_LLVM_VERSION_STRING like the other build systems do
Eric Engestrom - panfrost: Implement depth range clipping
Alyssa Rosenzweig: This should fix glDepthRangef issues. - nir: Add explicit signs to image min/max intrinsics
Jason Ekstrand: This better matches all the other atomic intrinsics such as those for SSBOs and shared variables where the sign is part of the intrinsic opcode. - pan/decode: Validate swizzles against format
Alyssa Rosenzweig: We want to make sure we don't access a component in the swizzle that doesn't exist in the format, since that is (as far as I know) undefined. - pan/decode: Add static bounds checking utility
Alyssa Rosenzweig: Many structures in the command stream have a GPU address and size determined statically. - i965: Enable OpenGL 4.6 for Gen8+
Alejandro Piñeiro: The last remaining stuff was ARB_gl_spirv and ARB_spirv_extensions. - mesa/version: uncomment SPIR-V extensions
Alejandro Piñeiro: As they are implemented on i965, so we can expose 4. - radv: force enable VK_AMD_shader_ballot for Wolfenstein Youngblood
Samuel Pitoiset: This gives a nice boost, +20% at this time on my Vega 56. - radv: allow to enable VK_AMD_shader_ballot only on GFX8+
Samuel Pitoiset: Scans aren't implemented on SI/CIK. - nir/loop_analyze: Treat do{}while(false) loops as 0 iterations
Danylo Piliaiev: Loops like: - lima/ppir: use ra_get_best_spill_node to select spill node
Erico Nunes: ra_get_best_spill_node is what other users of the mesa register allocator use. - gitlab-ci: Enable the GLES2/3 CTS on softpipe
Eric Anholt: The GLES2 CTS takes about 8 minutes of total runtime (at parallel 4 is ~2 minutes in the test stage if runners are free), while GLES3 takes about 25. - iris: Enable non coherent framebuffer fetch on broadwell
Sagar Ghuge - iris: Add infrastructure to support non coherent framebuffer fetch
Sagar Ghuge: Create separate SURFACE_STATE for render target read in order to support non coherent framebuffer fetch on broadwell. - iris: Add render target read entry in binding table
Sagar Ghuge: This will be used in next patches for supporting non coherent framebuffer fetch on Broadwell. - panfrost: Add madvise support to BO cache
Rob Herring: The kernel now supports madvise ioctl to indicate which BOs can be freed when there is memory pressure. - panfrost: Sync UAPI header from kernel
Rob Herring: Sync the panfrost_drm.h UAPI header with the latest from the kernel. - mesa: add ext_dsa GetMultiTexLevelParameterEXT
Pierre-Eric Pelloux-Prayer - radv: Add Renoir support
Bas Nieuwenhuizen: Took the freedom to enable dfsm even though I don't have benchmark results yet, but it seems Raven-like. - etnaviv: rs: add support for 64bpp clears
Christian Gmeiner: Starting with HALTI2 the RS supports 64bpp clears. - pan/midgard: Compute liveness per-block
Alyssa Rosenzweig: Rather than using a regalloc based on live internals, computed hastily with repeated invocations of a forward-analysis pass, we switch to compute liveness information on a per-block basis. Within a given basic block, we compute liveness backwards with a linear-time algorithm; for common shaders, this may help RA terminate quicker. Across blocks, we use a work list (really a work set) and check if we're making progress. - pan/midgard: Add mir_foreach_predecessor utility
Alyssa Rosenzweig: It's ugly, but c'est la vie.
Mesa Release Tags
- scons: define MESA_LLVM_VERSION_STRING like the other build systems do
Eric Engestrom - lima/ppir: use ra_get_best_spill_node to select spill node
Erico Nunes: ra_get_best_spill_node is what other users of the mesa register allocator use. - radv: consider MESA_VK_VERSION_OVERRIDE when setting the api version
Eleni Maria Stea: Before setting the physical device API version, we should check if the MESA_VK_VERSION_OVERRIDE environment variable is set and take it into account. - simplify LLVM version string printing
Eric Engestrom: Figure it out once in the build system, then just use that all over the place. - freedreno: fix release tarball
Rob Clark: Fixes: b4476138d5a freedreno: move drm to common location - freedreno: more fixing release tarball
Rob Clark: Fixes: aa0fed10d35 freedreno: move ir3 to common location - vulkan/utils: s/VERSION/PACKAGE_VERSION/
Eric Engestrom: Everything else uses PACKAGE_VERSION, so let's be consistent, and - build: stop defining unused VERSION
Eric Engestrom: Scons and autotools don't define it, and as of last commit nothing uses it. - autotools, meson: bump up required VA version
Juan A. Suarez Romero: Due using a new VP9 config we use, required VA API 0.39 - mesa: simplify MESA_GL_VERSION_OVERRIDE behavior of API override
Marek Olšák: v2: - Provide a correct explanation on the envvars documentation (Ian). - Provide a more correct explanation on the function comments (Andres). v3: - Homogenize documentation and inline comments (Emil). - Correct a typo (Emil). Fixes: 2599b92eb97 ("mesa: allow forcing >=3.1 compatibility contexts with MESA_GL_VERSION_OVERRIDE") Cc: Jordan Justen Cc: Ian Romanick Cc: Eric Engestrom Cc: Emil Velikov
Most Popular In The Past Month
- meson: bump required version to 0.46
Eric Engestrom: 0.45 has a few annoying bugs (like the one in !358 [1]), and 0.46 is well over a year old by now, so let's move to it. - nir: add access to image_deref intrinsics
Lionel Landwerlin: SPIRV added the ability to access variables and have expressions non dynamically uniform and because spirv_to_nir generates deref instructions, we'll need to have that access there. - nir: Optimize umod lowering
Sagar Ghuge: We don't have calculate final quotient in order to calculate unsigned modulo result. - panfrost: Add support for decoding gl_FrontFacing
Alyssa Rosenzweig - etnaviv: rs: add support for 64bpp clears
Christian Gmeiner: Starting with HALTI2 the RS supports 64bpp clears. - etnaviv: add alternative NIR compiler
Jonathan Marek - amd: add support for Arcturus
Marek Olšák - panfrost: Add MALI_ATTR_IMAGE value
Alyssa Rosenzweig: Images are implemented (in part) as special attributes, so include support for decoding this. - radeonsi: add support for compute-only chips
Marek Olšák - panfrost: Implement transform feedback
Alyssa Rosenzweig: Midgard has no hardware support for transform feedback, so we simulate it in software.
