[CK] Fix warp tile combination selection in absence of a GPU (#5213) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Motivation The `get_gpu_name_by_id()` function in `gemm_streamk_validation_utils.py` relies on `rocminfo` to detect the GPU architecture at runtime. However, __`rocminfo` fails in CI/build environments__ where: - No physical GPU is present - ROCm tools are not installed - The build is running in a container without GPU access In any of these environments, the problem manifests itself in incorrect kernel validation and will generate template instantiations that do not exist: ``` [composable_kernel] FAILED:

Technical Details ### Changes Made: #### 1. __gemm_streamk_validation_utils.py__ - Added module-level storage: `_configured_gpu_targets` - Added `set_gpu_targets(targets: List[str])` to configure fallback GPU targets - Added `get_configured_gpu_targets() -> List[str]` to retrieve configured targets - Enhanced `get_gpu_name_by_id()` to: - First try `rocminfo` (existing behavior) - If `rocminfo` fails, fall back to first configured GPU target - Extract base gfx name (e.g., "gfx90a" from "gfx90a:xnack+") - Log debug messages when using fallback #### 2. __gemm_streamk_instance_builder.py__ - Added `--gpu_targets` command-line argument - Automatically calls `set_gpu_targets()` when `--gpu_targets` is provided - Parses semicolon-separated GPU target list from CMake #### 3. __test/ck_tile/gemm_streamk_tile_engine/CMakeLists.txt__ - Modified both `--list_kernels` and `--gen_single` invocations to pass `--gpu_targets "${SUPPORTED_GPU_TARGETS}"` - GPU targets are now automatically wired from CMake to Python scripts ### How It Works: 1. __CMake Configuration__: `SUPPORTED_GPU_TARGETS` is determined from `GPU_TARGETS` or defaults 2. __CMake → Python__: CMake passes targets via `--gpu_targets` argument to Python scripts 3. __Python Configuration__: Scripts call `set_gpu_targets()` to configure the fallback 4. __Fallback Mechanism__: When `rocminfo` fails, `get_gpu_name_by_id()` uses the first configured target 5. __Target Parsing__: Extracts clean gfx name (e.g., "gfx90a" from "gfx90a:xnack+") ## Test Plan Confirm that only the appropriate kernels are selected and that CI passes. ## Test Result 1. Waiting on CI 2. Compilation succeeded locally and the kernel list does not contain the 16x16x8 kernel for gfx942 anymore: ``` (.venv) bhargrea@ctr-cx66-mi300x-02:~/github/TheRock$ cat build/ml-libs/composable_kernel/build/test/ck_tile/gemm_streamk_tile_engine/fp16/rcr/streamk_atomic_smoke_tests_config_fp16/gemm_kernel_list.txt gemm_fp16_rcr_compv3_cshuffle_intrawave_Atomic_False_False_False_True_256x256x32_2x2x1_16x16x16|256x256x32_2x2x1_16x16x16|compv3_cshuffle_intrawave_atomic_False_False_False_True gemm_fp16_rcr_compv3_cshuffle_intrawave_Atomic_False_False_False_False_256x256x32_2x2x1_16x16x16|256x256x32_2x2x1_16x16x16|compv3_cshuffle_intrawave_atomic_False_False_False_False gemm_fp16_rcr_compv3_cshuffle_intrawave_Atomic_False_False_False_True_256x256x32_2x2x1_16x16x32|256x256x32_2x2x1_16x16x32|compv3_cshuffle_intrawave_atomic_False_False_False_True gemm_fp16_rcr_compv3_cshuffle_intrawave_Atomic_False_False_False_False_256x256x32_2x2x1_16x16x32|256x256x32_2x2x1_16x16x32|compv3_cshuffle_intrawave_atomic_False_False_False_False gemm_fp16_rcr_compv3_cshuffle_intrawave_Atomic_False_False_False_True_256x256x32_2x2x1_32x32x8|256x256x32_2x2x1_32x32x8|compv3_cshuffle_intrawave_atomic_False_False_False_True gemm_fp16_rcr_compv3_cshuffle_intrawave_Atomic_False_False_False_False_256x256x32_2x2x1_32x32x8|256x256x32_2x2x1_32x32x8|compv3_cshuffle_intrawave_atomic_False_False_False_False gemm_fp16_rcr_compv3_cshuffle_intrawave_Atomic_False_False_False_True_256x256x32_2x2x1_32x32x16|256x256x32_2x2x1_32x32x16|compv3_cshuffle_intrawave_atomic_False_False_False_True gemm_fp16_rcr_compv3_cshuffle_intrawave_Atomic_False_False_False_False_256x256x32_2x2x1_32x32x16|256x256x32_2x2x1_32x32x16|compv3_cshuffle_intrawave_atomic_False_False_False_False ``` ## Submission Checklist - [ x ] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.
