Yesterday's Activity

radv/winsys: allow to submit up to 4 IBs for chips without chaining
Samuel Pitoiset: The SI family doesn't support chaining which means the maximum size in dwords per CS is limited.

gallium/util: Android backtrace support
Stefan Schake: We can't use any of the existing implementations in u_debug_stack.

Other Activity This Week

compiler: Add SYSTEM_VALUE_FIRST_VERTEX and instrinsics
Antia Puentes: This VS system value will contain the value passed as <basevertex> for indexed draw calls or the value passed as <first> for non-indexed draw calls.

radv: Add bound checking workaround for dynamic buffers
Bas Nieuwenhuizen: I have seen a few applications and games do the dynamic buffer bounds incorrectly, this make it easier to work around, e.g.

radv: enable DCC for MSAA 2x textures on VI under an option
Samuel Pitoiset: This can be enabled with RADV_PERFTEST=dccmsaa. DCC for MSAA textures is actually not as easy to implement.

radv: decompress DCC for multisampled source images before resolving
Samuel Pitoiset: Multisampled source images (ie.

radv: add a workaround for fast clears with DCC and MSAA textures
Samuel Pitoiset: This should be fixed at some point in order to improve performance.

radv: implement fast color clear for DCC with MSAA
Samuel Pitoiset: When DCC is enabled with MSAA textures, CMASK should be cleared to 0xCCCCCCCC.

radv: make sure to sync after resolving using the compute path
Samuel Pitoiset: This fixes some random CTS failures:

spirv: Add support for VK_EXT_descriptor_indexing uniform indexing caps
Bas Nieuwenhuizen

radv: Add support for variable descriptor set layouts
Bas Nieuwenhuizen

radv: Keep a global BO list for VkMemory
Bas Nieuwenhuizen: With update after bind we can't attach bo's to the command buffer from the descriptor set anymore, so we have to have a global BO list. I am somewhat surprised this works really well even though we have implicit synchronization in the WSI based on the bo list associations and with the new behavior every command buffer is associated with every swapchain image.

radeonsi: add support for VegaM
Marek Olšák

amd/addrlib: add support for VegaM
Marek Olšák

swr/rast: Optimize late/bindless JIT of samplers
George Kyriazis

swr/rast: minimize codegen redundant work
George Kyriazis

swr/rast: Add shader stats infrastructure (WIP)
George Kyriazis

swr/rast: Add vgather to x86 lowering pass
George Kyriazis: Add support for generic VGATHERPD intrinsic in x86 lowering pass.

swr/rast: add cvt instructions in x86 lowering pass
George Kyriazis: Support generic VCVTPD2PS and VCVTPH2PS in x86 lowering pass.

swr/rast: Change gfx pointers to gfxptr_t
George Kyriazis: Changing type to gfxptr for indices and related changes to fetch and mem builder code.

swr/rast: Add support for setting optimization level
George Kyriazis

swr: add x86 lowering pass to fragment shader
George Kyriazis: Needed because some FP paths (namely stipple) use gather intrinsics that now need to be lowered to x86.

swr/rast: Enable generalized fetch jit
George Kyriazis: Enable generalized fetch jit with 8 or 16 wide SIMD target.

swr/rast: Lower VGATHERPS and VGATHERPS_16 to x86.
George Kyriazis: Some more work to do before we can support simultaneous 8-wide and 16-wide and remove the VGATHERPS_16 version.

swr/rast: Lower PERMD and PERMPS to x86.
George Kyriazis: Add support for providing an emulation callback function for arch/width combinations that don't map cleanly to an x86 intrinsic.

swr/rast: Start refactoring of builder/packetizer
George Kyriazis: Move x86 intrinsic lowering to a separate pass.

swr/rast: Add some archrast counters
George Kyriazis: Hook up archrast counters for shader stats: instructions executed.

swr/rast: Add "Num Instructions Executed" stats intrinsic
George Kyriazis: Added a SWR_SHADER_STATS structure which is passed to each shader.

swr/rast: Add some archrast stats
George Kyriazis: Add stats for degenerate and backfacing primitive counts Wire archrast stats for alpha blend and alpha test.

swr/rast: Add some instructions to jitter
George Kyriazis

meson: Add library versions to swr drivers
Jan Alexander Steffens (heftig): This is for parity with autotools.

meson: add wrap for libdrm
Dylan Baker: Currently this requires libdrm from git, since the version reported by meson is wrong.

spirv: Add a 64-bit implementation of OpIsInf
Neil Roberts: The only change neccessary is to change the type of the constant used to compare against.

radeonsi: implement mechanism for IBs without partial flushes at the end (v6)
Marek Olšák: (This patch doesn't enable the behavior.

radv: don't fast-clear eliminate after resolving a subpass with compute
Samuel Pitoiset: That looks useless, and I think radv_handle_image_transition() will do a fast-clear eliminate because it's called after the resolve.

ac/nir: Make the GFX9 buffer size fix apply to image loads/atomics too
Bas Nieuwenhuizen: No clue how I missed those ...

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

mesa: adds some comments regarding MESA_GLES_VERSION_OVERRIDE usage
Andres Gomez: Fixes: 03fd6704db9 ("mesa: Add support for a new override string MESA_GLES_VERSION_OVERRIDE")

dri3: Fix typo in version check
Daniel Stone: The have-new-DRI3 codepaths would never actually properly trigger, since there was a typo in configure.ac which broke the version check.

freedreno: bump required libdrm version
Christian Gmeiner: Fixes: 26a9321d0a "freedreno: add global_bindings state"

meson: Add script to use VERSION file for getting version
Dylan Baker: Meson has up until this point set it's version in the root meson.build script, while the other build systems read the VERSION file.

mesa: don't use %s for PACKAGE_VERSION macro
Emil Velikov: The macro itself is a well defined string, which cannot cause issues with printf or other printf-like functions. All other places through Mesa already use it directly, so let's update the final two instances.

anv: Add MAX_API_VERSION to anv_extensions.py
Jason Ekstrand: The VkVersion class is probably overkill but it makes it really easy to compare versions in a way that's safe without the caller having to think about patch vs.

docs: add 17.2.0-devel release notes template, bump version

util: import sha1 implementation from OpenBSD
Emil Velikov: At the moment we support 5+ different implementations each with varying amount of bugs - from thread safely problems [1], to outright broken implementation(s) [2] In order to accommodate these we have 150+ lines of configure script and extra two configure toggles.

mesa: Bump the version to 17.0
Jason Ekstrand

Most Popular In The Past Month

i965: add performance query support on CNL
Lionel Landwerlin: v2: Add brw_oa_cnl.

i965: perf: add support for new equation operators
Lionel Landwerlin: Some equations of the CNL metrics started to use operators we haven't defined yet, just add those.

etnaviv: add perfmon query implementation
Christian Gmeiner: Add needed infrastructure to use performance monitor requests for queries.

radv: enable TC-compat HTILE for 16-bit depth surfaces on GFX8
Samuel Pitoiset: The hardware only supports 32-bit depth surfaces, but we can enable TC-compat HTILE for 16-bit depth surfaces if no Z planes are compressed. The main benefit is to reduce the number of depth decompression passes.

mesa: adds some comments regarding MESA_GLES_VERSION_OVERRIDE usage
Andres Gomez: Fixes: 03fd6704db9 ("mesa: Add support for a new override string MESA_GLES_VERSION_OVERRIDE")

i965: Add negative_equals methods
Ian Romanick: This method is similar to the existing ::equals methods.

meson: use dep_libdrm version for pkg-config
Dylan Baker: This corrects pkg-config to use the libdrm version (as computed by the previous patch) instead of using a hardcoded value that may or may not (probably not) be right.

radeonsi: add support for Vega12
Marek Olšák

vbo: Readd the arrays argument to the legacy draw methods
Mathias Fröhlich: The legacy draw paths from back before 2012 contained a gl_vertex_array array for the inputs to be used for draw.
