Head commit for run: 73e38d3f4447aa507cf795542aeffcc0948368b5 / Bohan Hou <[email protected]> [TIRx][CUDA] Add register and cluster launch controls (#20159) ## Summary - add a `tirx.max_registers` PrimFunc attribute and lower it to CUDA 13 `__maxnreg__` - reject combinations of the register cap with CUDA launch-bounds attributes - enable non-portable CUDA cluster sizes when a launch requests more than eight CTAs - keep launch attributes in fixed local storage and add CUDA codegen coverage ## Motivation SM100 TIRx kernels need an explicit register cap to preserve source-level occupancy and instruction scheduling. Large reduction kernels can also require 16-CTA clusters, which the CUDA driver rejects unless the non-portable cluster-size attribute is enabled. ## Impact TIRx kernels can opt into an exact CUDA register budget while retaining the existing launch-bounds path for other specializations. CUDA launches with cluster dimensions above eight are enabled only for kernels that request them; existing launch behavior remains unchanged. ## Validation - `cmake --build build --parallel` - `python -m pytest tests/python/tirx/codegen/test_codegen_cuda.py -q` (`201 passed`) - `pre-commit run --files include/tvm/tirx/function.h src/backend/cuda/codegen/codegen_cuda.cc src/backend/cuda/runtime/cuda_module.cc src/tirx/transform/split_host_device.cc tests/python/tirx/codegen/test_codegen_cuda.py` Report URL: https://github.com/apache/tvm/actions/runs/32556288920 With regards, GitHub Actions via GitBox --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
