Add signal-based synchronization for persistent GEMM kernels where
input data becomes available incrementally. Uses modulo wraparound
(like PyTorch's AsyncMM) for chunk index calculation:
chunk_idx = ((tile_idx + tile_idx_pivot) / tiles_per_chunk) % num_chunks
Key components:
- PersistentAsyncInputScheduler struct with tiles_per_chunk_m,
chunk_signals, tile_idx_pivot_m, and num_chunks fields
- wait_eq_wave method using __builtin_amdgcn_s_sleep for power efficiency
- IsSupportedArgument validation for scheduler parameters
- Example demonstrating async input scheduling with simulated producer
- GTest unit tests covering all layout combinations

* Add support to fp16 + compute fp16 and bf16 + compute bf16 contractions
Enables hipTensor to access the WMMA HW functionalities
for these combinations of datatype on gfx11 and gfx12.
* Fix change to contraction scale tests
* Fix clang-format
[ROCm/composable_kernel commit: 7d8bca7ddc]
This change improves the clang-format CI check to be faster and not
depend on git being available in the build environment.
Changes:
- Use `find` instead of `git ls-files` (no git dependency)
- Check all C++ files: *.h, *.hpp, *.cpp, *.h.in, *.hpp.in, *.cpp.in, *.cl
- Exclude build/ and include/rapidjson directories
- Use parallel processing with 8 cores (-P 8) for ~8x speedup
- Show only errors with unified diff format (-u)
- Clear error messages: "ERROR: <file> needs formatting"
- Preserve original logic: run clang-format only when RUN_CPPCHECK=false,
or run both clang-format and cppcheck when RUN_CPPCHECK=true
Performance:
- Sequential processing: ~93 seconds for 5,899 files
- Parallel with 8 cores: ~12 seconds for 5,899 files
- Per-file processing time: ~15ms
This reduces CI time while maintaining code formatting standards.

* Fix large case init bounds
* Revert "Fix large case init bounds"
This reverts commit 1abca05c6f.
* Restore CPU initialization for do_verification != 2
[ROCm/composable_kernel commit: 3f735c127b]
1. Added `-DCK_EXPERIMENTAL_BUILDER=OFF` to the `setup_args` to explicitly disable the experimental builder
2. Added a detailed comment explaining why this is necessary:
- SLES15 is a legacy platform with limited C++20 ecosystem support
- While the ROCm compiler supports C++20, the older system libraries and standard library implementation on SLES15 does not reliably support all C++20 features required by the experimental CK Builder
[ROCm/composable_kernel commit: 2d233c838a]
* Factor helpers out of conv_traits.hpp
* Create a non-templated conv_traits struct
* Migrate to new instance-specific instance_to_conv_traits functions
* Clean up reflection concepts
* Clean up ConvTraits helpers
* Update testing for convolution traits
This is a lot of cleanup on tests to have verbose coverage of feature
extraction, explicit tests for each supported device kernel, and
simple, readable test code.
* Address reviewer comments and resolve merge conflict
[ROCm/composable_kernel commit: 5122637215]
This is mostly adjustments to enum values so that the docs align correctly with the current code.
Also updated the calendar scope of the project to extend through March 2026.
[ROCm/composable_kernel commit: df7ee270a6]
The test_ck_tile_streamk_reduction test suite seems to have transient
failures; hence, we are disabling these tests for now. We will re-enable
them once the bug is resolved.
