Mesa
Mesa is an open-source 3D graphics library that provides the commonly-used DRI and Gallium3D open-source Linux graphics drivers.
Today's Activity
- nir: Add a bool to int32 lowering pass
Jason Ekstrand: We also enable it in all of the NIR drivers. - nir: Add support for 1-bit data types
Jason Ekstrand: This commit adds support for 1-bit Booleans and integers. - nir/algebraic: Make an optimization more specific
Jason Ekstrand: Later in this series, bool is not going to imply 32-bit. - nir: Drop support for lower_b2f
Jason Ekstrand: This was originally added for the out-of-tree Mali driver but I think we've all agreed it's easy enough for them to just do in their back-end.
Other Activity This Week
- pci_ids: add new vega10 pci ids
Alex Deucher - freedreno: debug GEM obj names
Rob Clark - freedreno/drm: sync uapi and enable softpin
Rob Clark: Pull in updated UAPI and use kernel API version to enable softpin. - mesa/st: Expose compute shaders when NIR support is advertised
Eric Anholt: We have a NIR path, and V3D doesn't have TGSI input for compute (only what TTN can handle for the various gallium-internal shaders). - i965: Enable nir_opt_idiv_const for 32 and 64-bit integers
Jason Ekstrand: The pass should work for all bit sizes but it's less clear that the extra instructions are worth it on small integers. - nir: Add a pass for lowering integer division by constants
Jason Ekstrand: It's a reasonably well-known fact in the world of compilers that integer divisions by constants can be replaced by a multiply, an add, and some shifts. - nir/lower_int64: Add support for [iu]mul_high
Jason Ekstrand - radv: allow to skip DCC decompressions with the new predicate
Samuel Pitoiset: Feral games aren't affected because they don't decompress DCC. - radv: add a predicate for reflecting DCC decompression state
Samuel Pitoiset: It's somehow similar to the FCE predicate. - nir: detect more induction variables
Timothy Arceri: This allows loop analysis to detect inductions variables that are incremented in both branches of an if rather than in a main loop block. - radv: bump reported version to 1.1.90
Samuel Pitoiset: After going through the spec changelog, it looks like RADV is up to date. - virgl: force linear texturing support
Erik Faye-Lund: When I made sure that half-float texture-filtering was required for ES3, I didn't realize that virgl doesn't report support for this correctly. - anv: Advertise support for MinLod on Skylake+
Jason Ekstrand: These are usually used for dealing with sparse resources but there's no reason why we can't hook them up before we have sparse. - intel/fs: Support min_lod parameters on texture instructions
Jason Ekstrand: We have to lower some shadow instructions because they don't exist in hardware and we have to lower txb+offset+clamp because the message gets too big and we run into the sampler message length limit of 11 regs. - nir/lower_tex: Add lowering for some min_lod cases
Jason Ekstrand - spirv: Add support for MinLod
Jason Ekstrand - freedreno: Add .dir-locals to the common directory
Neil Roberts: The commit aa0fed10d35 moved a bunch of Freedreno code to a common directory.
Mesa Release Tags
- 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 - 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.
Most Popular In The Past Month
- build: stop defining unused VERSION
Eric Engestrom: Scons and autotools don't define it, and as of last commit nothing uses it. - v3d: Add renderonly support
Eric Anholt: I've been using this with the kmsro series to test v3d on VKMS without my old KMS hack in the v3d kernel driver. - radv: implement fast HTILE clears for depth or stencil only on GFX9
Samuel Pitoiset: This allows to fast clear the depth part (or the stencil part) of a depth+stencil surface when HTILE is enabled. - drirc: enable glthread for Talos Principle
Marek Olšák: Ryzen 1700X, Vega 56, 1600x900, 4xAA: improvement +4.4% - i965: Add support for and expose EXT_texture_sRGB_R8
Gert Wollny: Emulate MESA_FORMAT_R_SRGB8 by using L8_UNORM_SRGB. - loader: Factor out the common driver opening logic from each loader
Eric Anholt: I copied the code from egl_dri2.c, but the functionality was equivalent between all the loaders other than their particular environment variables. v2: Drop the logging function equivalent to loader_default_logger() (requested by Eric, Emil). - glx: make xf86vidmode mandatory for direct rendering
Emil Velikov: Currently we detect the module and if missing, the glXGetMsc* API is effectively a stub, always returning false. - virgl: Clean up fences commit
Robert Foss: Remove a dead variable, a int->bool conversion and some whitespace changes. - r600: clean up the GS ring buffers when the context is destroyed
Gert Wollny: This fixes two memory leaks reported by ASAN: - nir: Make nir_lower_clip_vs optionally work with variables
Kenneth Graunke: The way nir_lower_clip_vs() works with store_output intrinsics makes a ton of assumptions about the driver_location field. In i965 and iris, I'd rather do this lowering early and work with variables.
