Today's Activity

iris: make the TFB result visible to others
Andrii Simiklit: OpenGL 4.6 Spec: "5.3.3 Rules Note: “Updates” via rendering or transform feedback are treated consistently with updates via GL commands.

iris: Some tidying for preemption support
Kenneth Graunke: Just enable it during init_render_context on Gen10+, and move the Gen9 state tracking into iris_genx_state so it only exists on Gen9.

radeonsi: remove dirty slot masks from scissor and viewport states
Marek Olšák: All registers in the array need to be updated if any of them is changed.

radeonsi: add radeonsi_sync_compile option
Nicolai Hähnle: Force the driver thread to sync immediately with a compiler thread (but compilation still happens in a separate thread).

radeonsi: add si_debug_options for convenient adding/removing of options
Nicolai Hähnle: Move the definition of radeonsi_clear_db_cache_before_clear there, as well as radeonsi_enable_nir. This removes the AMD_DEBUG=nir option. We currently still have two places for options: the driconf machinery and AMD_DEBUG/R600_DEBUG.

radeonsi: add BOs after need_cs_space
Marek Olšák: need_cs_space may clear the buffer list.

Yesterday's Activity

iris: enable preemption support for gen10
Mike Blumenkrantz

intel/fs: Fix D to W conversion in opt_combine_constants
Ian Romanick: Found by GCC warning: src/intel/compiler/brw_fs_combine_constants.cpp: In function ‘bool needs_negate(const fs_reg*, const imm*)’: src/intel/compiler/brw_fs_combine_constants.cpp:306:34: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] return ((reg->d & 0xffffu) < 0) != (imm->w < 0); ~~~~~~~~~~~~~~~~~~~^~~ The result of the bit-and is a 32-bit value with the top bits all zero.

panfrost/midgard: Remove assembler
Alyssa Rosenzweig: This code is outdated and unused; now that the compiler is mature, there's no point keeping it around in-tree (or at all).

panfrost: Adds Bifrost shader disassembler utility
Ryan Houdek: This code is stable and can live upstream independently while the rest of the Bifrost stack comes up.

panfrost/midgard: Implement copy propagation
Alyssa Rosenzweig: Most copy prop should occur at the NIR level, but we generate a fair number of moves implicitly ourselves, etc...

panfrost/midgard: Implement indirect loads of varyings/UBOs
Alyssa Rosenzweig: This adds preliminary support for indirect loads of varying arrays and uniform arrays, bringing a few new tests in shader.

Other Activity This Week

vulkan/wsi: Add X11 adaptive sync support based on dri options
Bas Nieuwenhuizen: The dri options are optional.

radv: Add support for driconf
Bas Nieuwenhuizen: This includes 0 options.

gallium: Remove the ondemand pipebuffer manager
Eric Anholt: I couldn't find any uses in the tree since its introduction.

gallium: Remove the pool pipebuffer manager
Eric Anholt: Noticed while trying to decide if pipebuffer was of any use to me, and found that nothing has used it in the last 10 years at least.

freedreno: a2xx: enable batch reordering
Jonathan Marek: Batch reordering on a2xx is now tested and functional.

svga: add new ATC formats to the format conversion table
Jonathan Marek: Fixes the static assertion error.

st/mesa: add ATC support
Jonathan Marek

llvmpipe, softpipe: no support for ATC textures
Jonathan Marek

gallium: add ATC format support
Jonathan Marek

iris: Replace buffer backing storage and rebind to update addresses
Kenneth Graunke: This implements PIPE_CAP_INVALIDATE_BUFFER and invalidate_resource(), as well as the PIPE_TRANSFER_DISCARD_WHOLE_RESOURCE flag.

intel/fs: Add a lowering pass for linear interpolation
Rafael Antognolli: On gen11, instead of using a PLN instruction, we convert FS_OPCODE_LINTERP to 2 or 4 multiply adds.

intel/fs: Move the scalar-region conversion to the generator
Rafael Antognolli: Move the scalar-region conversion from the IR to the generator, so it doesn't affect the Gen11 path.

i965: Ignore uniform storage for samplers or images, use binding info
Kenneth Graunke: gl_nir_lower_samplers_as_deref creates new top level sampler and image uniforms which have been split from structure uniforms.

drirc: Add workaround for Epic Games Launcher
Danylo Piliaiev: Epic Games Launcher could be launched in opengl mode with "-opengl" option.

iris: Add mechanism for iris-specific driconf options
Kenneth Graunke: Based on Nicolai's 0f8c5de8690e7c87aa2e24383065efaca7e6fe78.

anv,radv: Update release notes for newly implemented extensiosn
Jason Ekstrand: A lot has happened in those two drivers since the 19.0 release and we keep forgetting to update release notes.

intel/fs: Add support for bindless image load/store/atomic
Jason Ekstrand

anv: Use bindless textures and samplers
Jason Ekstrand: This commit changes anv to put bindless handles and sampler pointers into the descriptor buffer and use those instead of bindful when we run out of binding table space.

intel/fs: Add support for bindless texture ops
Jason Ekstrand: We add two new texture sources for bindless surface and sampler handles.

anv: Implement SSBOs bindings with GPU addresses in the descriptor BO
Jason Ekstrand: This commit adds a new way for ANV to do SSBO bindings by just passing a GPU address in through the descriptor buffer and using the A64 messages to access the GPU address directly.

anv: Lower some SSBO operations in apply_pipeline_layout
Jason Ekstrand: In order to avoid the potential overhead of A64 operations on all SSBO ops, we look for those SSBO ops where we can get to the descriptor set from the SSBO access operation and lower those to a binding-table approach.

anv: Make all VkDeviceMemory BOs resident permanently
Jason Ekstrand: We spend a lot of time in the driver adding things to hash sets to track residency.

lima: enable nir fsign lowering in ppir
Erico Nunes: The mali utgard pp doesn't support a sign instruction.

nir/algebraic: add lowering for fsign
Erico Nunes: The mali utgard pp doesn't support a sign instruction.
