[CK_TILE] Separate PermuteN epilogue from CShuffle epilogue into standalone file (#5863) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Motivation The PermuteN epilogue was previously embedded within cshuffle_epilogue.hpp, despite having fundamentally different behaviour. Coupling these two independent strategies in one file introduced unnecessary complexity, SFINAE guards, and a dual operator() overload selected at compile time via TiledMMAPermuteN_ template parameter. This PR separates PermuteN into its own standalone file(pertmuten_epilogue.hpp), simplifying both implementations and making the codebase easier to maintain and extend independently. ## Technical Details **New file: permuten_epilogue.hpp:** contains PermuteNEpilogueProblem and PermuteNEpilogue, extracted from the permuteN code path in cshuffle_epilogue.hpp. **Cleanup of cshuffle_epilogue.hpp:** - Removed the TiledMMAPermuteN_ template parameter from [CShuffleEpilogueProblem] - Removed the SFINAE-guarded permuteN operator() overload - Removed the EnablePermuateN_ SFINAE alias - CShuffle now only contains CShuffle logic; EightWave support (independent feature) is retained **Consumer migration :** All consumer files now use compile-time epilogue selection via [std::conditional_t] `using GemmEpilogue = std::conditional_t< TiledMMAPermuteN, PermuteNEpilogue<PermuteNEpilogueProblem<...>>, CShuffleEpilogue<CShuffleEpilogueProblem<...>>>;` **Files modified:** - flatmm_basic.cpp, moe_flatmm.cpp, a16w4_moe_flatmm.cpp, mixed_prec_flatmm.cpp, mx_flatmm_instance.hpp — flatmm examples - run_gemm_quant_example.inc — block-scale GEMM example - gemm_weight_preshuffle_invoker.hpp — weight preshuffle invoker - test_gemm_quant_fixtures.hpp, test_gemm_persistent_async_input.cpp, test_gemm_pipeline_util.hpp — test utilities - universal_gemm_invoker.hpp — universal GEMM invoker - epilogue.hpp — add header updated to include permuten_epilogue.hpp ## Submission Checklist - [x] Look over the contributing guidelines at https://github.com/ROCm/ROCm/blob/develop/CONTRIBUTING.md#pull-requests.
