# Add gfx950 MXFP4 Subtile-based kernel implementation ## Summary This PR is a follow-up to #6499 ([hipblaslt] Add support for gfx950 mxfp4) and adds the **Subtile-based kernel implementation (`UseSubtileImpl=1`)** for hipBLASLt on **gfx950**. It introduces a new tile-decomposed code generation path optimized for **MXFP4** and **BF16** GEMMs, plus the solution-selection plumbing, validation, Origami logic yamls, and unit tests needed to make it production-usable. ## Motivation PR #6499 brought MX data type support online for gfx950, but the existing TensileLite codegen path leaves significant performance on the table for MXFP4-heavy workloads. The Subtile path restructures global-read / local-read / MFMA / store scheduling at a finer granularity, which **greatly improves MXFP4 GEMM performance when using `HIPBLASLT_MATMUL_MATRIX_SCALE_BLK32_UE8M0_32_8_EXT`** (added to the hipBLASLt CHANGELOG). ## What's included ### 1. New Subtile-based kernel components (Tensile) New modules under `projects/hipblaslt/tensilelite/Tensile/Components/`: * `SubtileBasedKernel.py` (~1850 LOC) — entry point and orchestration of the subtile codegen path; replaces large portions of the standard prefetch / unroll / store flow when `UseSubtileImpl=1`. * `SubtileBasedLogicalScheduler.py` (~2415 LOC) — logical scheduler that builds the subtile-grained instruction graph (GR loads, LR offsets, MFMA tiles, scale loads, stores) from kernel parameters. * `SubtileBasedInstructionScheduler.py` (~433 LOC) — converts the logical schedule to an emit order respecting wave / register / hazard constraints. * `SubtileBasedInstructionEmitter.py` (~216 LOC) — instruction emission helpers shared by the subtile components. ### 2. Kernel writer / common changes * **`KernelWriter.py`**, **`KernelWriterAssembly.py`**: integration points for the subtile path — prefetch, GR offset calculation, LR offset calculation, post-loop, MFMA macro accounting, optimized `storeD`, LDS buffer swap, MX FP4 scale emit, `SrdMXSA/B+2` handling, sgpr allocation / overflow guards, computeLoadSrd fix. * **`SolutionStructs/Solution.py`**, **`SolutionStructs/Problem.py`**: introduces the `UseSubtileImpl` parameter, MX-related reject conditions for non-Subtile paths on gfx950, and additional valid GEMM type combinations for MX inputs. * **`Common/ValidParameters.py`**, **`Common/RequiredParameters.py`**, **`Common/GlobalParameters.py`**: `UseSubtileImpl` registration and defaults. * **`Components/StreamK.py`**: subtile-aware StreamK fixup (incl. import union with the `BufferLoadB32` cache-coherence change from #6837). * **`Components/GlobalWriteBatch.py`**: optimized global write batching for the subtile path (~670 LOC of changes). * **`Components/ComputeStoreVgprs.py`**, **`Components/LSU.py`**, **`Components/WorkGroupMappingAlgos.py`**, **`AsmStoreState.py`**, **`KernelWriterModules.py`**: minor adjustments needed by the subtile pipeline. ### 3. rocisa / host / client * **`rocisa/rocisa/include/container.hpp`**: helpers needed by the new emitter. * **`tensile_host.cpp`**, **`include/Tensile/TensorDescriptor.hpp`**: small fixups for the subtile path and gfx950 build. * **`client/include/DataInitialization.hpp`**, **`client/src/DataInitialization.cpp`**, **`client/src/Reference.cpp`**, **`client/src/ReferenceValidator.cpp`**, **`client/include/TypedId.hpp`**: MX scale init and reference paths used by the new tests. * **`clients/common/include/testing_matmul.hpp`**, **`clients/common/include/norm.hpp`**, **`clients/common/include/hipblaslt_datatype2string.hpp`**, **`clients/common/src/mxDataGen.cpp`**: wiring for batched (>1) testing and MX init. ### 4. Origami / solution selection (gfx950 MXFP4) New auto-tuned logic yamls under `projects/hipblaslt/library/.../Tensile/Logic/asm_full/gfx950/gfx950/Origami/` covering the FP4 SS / HS / BS variants in three layouts: * `Origami/` (default) * `Origami/Origami_nta4/` (no-transpose-A FP4) * `Origami/Origami_ntb4/` (no-transpose-B FP4) (9 new `gfx950_Cijk_Alik_Bljk_F4{SS,HS,BS}_MXA32_MXB32_*_UserArgs.yaml` files in total.) ### 5. New tests **End-to-end gfx950 GEMM yamls** in `Tensile/Tests/common/gemm/gfx950/`: * `subtile_bf16.yaml`, `subtile_mxfp4.yaml` * `mx32f4_tn.yaml`, `mx32f8_tn.yaml` * `mxfp4_mxfp4_{fp32,bf16}_tn_act{,_groupgemm}.yaml` * `mxfp4_fp8_{fp32,bf16}_tn_act{,_groupgemm}.yaml` * `fp8_mxfp4_{fp32,bf16}_tn_act{,_groupgemm}.yaml` **StreamK + MX:** `Tensile/Tests/common/streamk/sk_mx32f4_quick.yaml`, `sk_mx32f8_quick.yaml`. **New unit tests** (`Tensile/Tests/unit/`): * `test_SubtileBasedLogicalScheduler.py` (~1735 LOC) * `test_SubtileBasedSchedulerRef.py` (~596 LOC) * `test_gr_lr_roundtrip.py` (~571 LOC) * `test_storeD_roundtrip.py` (~2420 LOC) * `test_graTileAssignment.py` (~354 LOC) * `test_lraTileAssignment.py` (~360 LOC) * `conftest.py`, `gpu_test_helpers.py` shared fixtures (~601 LOC) **New gtest:** `tensilelite/tests/MXScalePadding_test.cpp`. ### 6. Misc / hardening * Reject conditions: gfx950 MX + non-Subtile, DepthU constraints, GroupGEMM not yet supported with StreamK + MX, AssertSummationElementMultiple=256 for subtile MXFP4, missing-mxblock check for non-MX types. * Skip rocRoller for FP4-A/FP4-B with pre-swizzled scale layout (#42). * `forceDenorm=False` in `generateMXInput` (#11). * Several rebase fixes, copyright/year header updates, and review-comment fixes to `KernelWriter` / `KernelWriterAssembly`. ### 7. CHANGELOG Greatly improved MXFP4 GEMM performance when using HIPBLASLT_MATMUL_MATRIX_SCALE_BLK32_UE8M0_32_8_EXT ## How to use Set `UseSubtileImpl: 1` on a gfx950 MX-FP4 solution (see the new `subtile_mxfp4.yaml` / `mx32f4_tn.yaml` for canonical configs). The path is opt-in — non-MX and non-gfx950 kernels are unaffected. ## Backwards compatibility / risk * All new behavior is gated on `UseSubtileImpl=1` and gfx950. Existing solutions on other architectures or non-MX paths are unchanged. * `GroupGEMM + StreamK + MX` is intentionally rejected for now (TODO). * New Origami yamls only add solutions; nothing existing is modified. ## Test plan * New gtests + unit tests run automatically in CI (Tensilelite Python unit suite, `MXDataGen_test`, `MXScalePadding_test`). * New end-to-end gfx950 GEMM and StreamK yamls are added to the common test buckets. * Manual: run the gfx950 MXFP4 subtile suites (`pytest -k gfx950` after building Tensile, plus `tensilelite-client --yaml subtile_mxfp4.yaml` for sanity). ## Notes for reviewers * This branch was rebased onto current `develop` (post-#6499) by skipping the `users/nakajee/gfx950_mx_rebase_merge` history (which #6499 squash-merged) and replaying only the subtile-specific work as a single squashed commit. The actual code changes in this PR are limited to the files listed above (24 added, 56 modified; ~+170k / −2.6k including generated logic yamls). * The largest reviewable diffs are: * `Tensile/Components/SubtileBased{Kernel,LogicalScheduler,InstructionScheduler,InstructionEmitter}.py` (new files) * `Tensile/KernelWriter.py`, `Tensile/KernelWriterAssembly.py` * `Tensile/SolutionStructs/{Problem,Solution}.py` * `Tensile/Components/{GlobalWriteBatch,StreamK}.py` * `clients/common/include/testing_matmul.hpp` * `client/src/DataInitialization.cpp` * Description of all commits that were squashed for this feature branch: Subtile implementation for gfx950 MX FP4 --- 272f88d: Add sample subtile impl --- Author: brianshi <brianshi@amd.com> --- 60ecede: GR Offset calculation (#1) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- be69c1d: Enable post-loop code generation, and add some subroutines --- Author: b-shi <brianshi@amd.com> --- 646d102: LR offset calculation (#2) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- 71f4bca: Add GR load emit logic, and misc fixes (#3) --- Author: b-shi <brianshi@amd.com> --- 1fd0db9: Emit LR + init ACCVGPR (#4) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- 9d406b9: Add loop and ptr update code --- Author: b-shi <brianshi@amd.com> --- b6127bc: Update GR/LR offset calculation to fully support 2x2, 1x4, 4x1 waveConfigs (#7) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- 89ec87c: Account for valuC macro value in SK WS store code --- Author: b-shi <brianshi@amd.com> --- 6edf53d: Rebase fix --- Author: b-shi <brianshi@amd.com> --- 34e79fc: Enable fp4 (#8) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- d5a5c57: [Tensilelite] Add MX FP4 scale offset computation for subtile-based kernel (#6) --- Author: Archana Ramalingam <98564406+archana-ramalingam@users.noreply.github.com> --- 7a8a85a: Add lds buffer swap logic --- Author: b-shi <brianshi@amd.com> --- d24a8fe: Add optimized storeD code (#9) --- Author: b-shi <brianshi@amd.com> --- a45c20c: Fix MX scale tensor initialization: set forceDenorm=false in generateMXInput (#11) --- Author: T.J.

…7008) ## Motivation Several memory leaks were detected in MIOpen gtests using ASan. Some of the tests were blacklisted and others were not. This change looks to fix all of the low hanging fruit, which are the majority of the leaks found. This includes all of the critical leaks (>100MB) that were reported. Some other leaks were identified as needing a larger refactor to resolve. After fixing the w_supertensor.cpp leak, the supertensor tests hit virtual memory area limit errors. These changes are to enable running them with ASan, but only with a subset of the tests in order to not hit limits. The test coverage being lost is fairly negligible and the full tests are still run without ASan enabled. ## Technical Details Here is a summary of the files looked at and the changes made: | File | Status | Notes | |------|--------|-------| | `test/gtest/gpu_mha_forward.cpp` | Fixed | Added `miopenDestroySolution()` loop after using solutions. Fixes MHA forward solution descriptor leaks (report #11, #13). | | `test/gtest/gpu_mha_backward.cpp` | Fixed | Added `miopenDestroySolution()` loop after using solutions. Fixes MHA backward solution descriptor leaks (report #9, #12). | | `test/gtest/mha_find20.cpp` | Fixed | Added `miopenDestroySolution()` loop in both `MhaForward` and `MhaBackward` tests. Fixes MHA Find2.0 solution leak (report #16). | | `test/gtest/gtest_desc_guard.hpp` | Fixed | New shared header introduced by the refactor. Provides a single `DescGuard<DescType, CreateFn, DestroyFn>` template (with `TensorDescGuard`, `ConvDescGuard`, `DropoutDescGuard`, `RNNDescGuard` aliases), a `HandleGuard` RAII wrapper for `miopenHandle_t`, and the `DestroyInternalRnnDropoutDesc(rnnDesc)` helper used by every RNN/LSTM/GRU test to free the internal `DropoutDescriptor` that `miopenCreateRNNDescriptor` allocates and `miopenSetRNNDescriptor*` then leaks. Replaces the per-file ad-hoc guard structs from the initial implementation. | | `test/gtest/w_supertensor.cpp` | Fixed | Switched raw descriptors to the shared `RNNDescGuard` / `TensorDescGuard` from `gtest_desc_guard.hpp`. Added a class-local `DestroyDropoutDesc()` (called from `TearDown` and before `miopenSetRNNDescriptor`) to prevent the `miopenSetRNNDescriptor` overwrite leak. Reduced test parameter space under ASan to avoid OOM. Removed unused `seqLen` parameter and dead `param_dev_out`/`bias_dev_out` allocations. | | `test/gtest/lstm.hpp` | Fixed | Switched `rnnDesc` → `RNNDescGuard`, `DropoutDesc` → `DropoutDescGuard`, and `mio_handle` → `HandleGuard` (which now owns the `miopenDestroy` call), all from the shared `gtest_desc_guard.hpp`. Hoisted `dropout_state_buf` so it can be `hipFree`d at the end of the dropout path. Added `DestroyInternalRnnDropoutDesc(rnnDesc)` before `miopenSetRNNDescriptor*` and (in the non-dropout path only) at end of `Run`, which frees the internal `DropoutDescriptor` that the Set call would otherwise leak. Fixes ~615 MB dropout leaks and ~16.5 KB non-dropout descriptor leaks (report #3, #4, #6, #17-#22). | | `test/gtest/gru_test.cpp` | Fixed | In the GRU test class: switched `rnnDesc` → `RNNDescGuard`, `DropoutDesc` → `DropoutDescGuard`, `mio_handle` → `HandleGuard`, and added `DestroyInternalRnnDropoutDesc(rnnDesc)` before `miopenSetRNNDescriptor*` and (non-dropout path only) at end of `Run` plus `hipFree(dropout_state_buf)` for the dropout path. In the in-file `GRUFwdCPUVerify` / `GRUBwdDataCPUVerify` helpers: converted the raw `dropout_inputTensor` / `dropout_outputTensor` declarations to `TensorDescGuard` (mirroring the `cpu_rnn.hpp` change for the LSTM/RNN helpers). | | `test/gtest/softmax_find20.cpp` | Fixed | Changed `Finalize()` to take the `std::vector<miopenSolution_t>&` and destroy each solution via `miopenDestroySolution()` before destroying the problem. Updated all 6 `TEST(...)` callers to pass the solutions vector. Fixes Find2.0 softmax solution/kernel leaks (report #25-#27). | | `test/gtest/rnn_seq_api.hpp` | Fixed | Hoisted `dropout_state_buf` so the dropout path can `hipFree` it at the end. Added `DestroyInternalRnnDropoutDesc(&rnnDesc)` before `miopenSetRNNDescriptor*` and (non-dropout path only) at end of the run to free the internal `DropoutDescriptor` allocations leaked by `RNNDescriptor` copy-assignment. Same pattern as the LSTM/GRU fixes (report #29-#30). | | `test/cpu_rnn.hpp` | Fixed | Converted 6 raw `miopenTensorDescriptor_t dropout_input/outputTensor` declarations across the LSTM/RNN CPU verification helpers (`LSTMFwdCPUVerify`, `LSTMBwdDataCPUVerify`, `RNNFwdTrainCPUVerify`, `RNNBwdDataCPUVerify`, `GRUFwdCPUVerify`, `GRUBwdDataCPUVerify`) to the shared `TensorDescGuard` from `gtest_desc_guard.hpp`. Removed the redundant `miopenCreateTensorDescriptor` calls and updated 12 `miopen::deref(...)` sites to `.get()`. (Note: the GRU helpers in this header are stale duplicates; the live ones are inside `test/gtest/gru_test.cpp` and were updated there too.) Fixes the LSTM/GRU CPU-verify tensor descriptor leaks (report #1, #2, #14, #15, #32, #33). | | `test/gtest/rnn_vanilla_common.hpp` | Fixed | Added `DestroyInternalRnnDropoutDesc(rnnDesc)` calls before `miopenSetRNNDescriptor*` and (non-dropout path only) at end of the run. The `RNNDescGuard` / `DropoutDescGuard` usage was already in place from an earlier commit and now resolves to the shared definitions in `gtest_desc_guard.hpp`. Same pattern as LSTM/GRU/rnn_seq_api fixes (report #14, #15, #32, #33). | | `test/gtest/graphapi_gtest_common.hpp` | Skipped | File no longer exists in the codebase. The GraphApi test infrastructure has been removed; only the leak report (a stale snapshot) still references it. No fix possible against the current source tree. | | `test/gtest/graphapi_execution_plan.cpp` | Skipped | File no longer exists in the codebase (GraphApi removed). The leak it represented was largely an external hipblaslt bug anyway; the remaining test-side portion is not fixable against the current source. | | `test/gtest/na_train.cpp` / `na_inference.cpp` / `na_*_find2.cpp` | Skipped | Leaks come from the internal MIOpen solver/kernel cache living on the global singleton handle, which is never destroyed. Not easily fixable without redesigning global handle lifecycle. Should be suppressed in the ASan suppression file. | | hipblaslt / rocblaslt (external) | Skipped | `SolutionCache::addKernel` and `preloadCustomKernels` leak via `_rocblaslt_handle` constructor. Called from `miopen::Handle::CreateHipblasLtHandle`. This is an upstream bug in hipblaslt/rocblaslt, not fixable in MIOpen. Affects suites that initialize a handle (report Category 2, Category 7). | | CLR / HIP runtime (external) | Skipped | `amd::Context` and `amd::roc::Device` global initialization leaks from `rocclr/platform/context.cpp`. HIP runtime internals, not fixable in MIOpen. | | `src/hipoc/hipoc_program.cpp` | Skipped | `HIPOCProgramImpl` objects leak during kernel compilation/caching (line ~178). This is an internal MIOpen kernel cache lifecycle issue that requires deeper architectural changes to fix. Contributes small amounts to MHA and Softmax Find2.0 leaks. | | `test/gtest/conv_api.cpp` | Fixed | Already clean against current source — `miopenDestroyConvolutionDescriptor(conv_desc)` call exists (line 24) inside the test loop. ASAN run reports no leaks. The leak report was based on a stale snapshot. The hipblaslt handle init portion is tracked under the external-skipped row. | | `test/gtest/log_test.cpp` (CPU_LOG_TEST_FUSION / CPU_LOG_TEST_NEG) | Fixed | Already clean against current source — `Tensor`, `Conv`, `CreateCBAFusionPlan`, `CreateBNormFusionPlan` all have proper destructors that call the corresponding `miopenDestroy*` APIs in `log.cpp`. ASAN run on `CPU_LOG_TEST_*` (11 tests across log_test.cpp + log_test_neg.cpp) reports no leaks. The hipblaslt handle init portion is tracked separately under the external-skipped row. | | `test/gtest/fusion_test.cpp` (CPU_FusionCreateOpConvForward) | Fixed | File renamed from `fusion.cpp` to `fusion_test.cpp`. Already clean against current source — uses `TensorDescGuard`/`ConvDescGuard` for tensor/conv descriptors and calls `miopenDestroyFusionPlan(fusionPlanDesc)` on the fusion plan (line 195). ASAN run on `CPU_FusionCreateOpConvForward_FP32.*` reports no leaks. | | `test/gtest/deterministic_conv_api.cpp` | Fixed | Already clean against current source — uses `ConvDescGuard` (line 66) for the conv descriptor. ASAN run on `*CPU_DeterministicConvApi*` reports no leaks. | | `test/gtest/fusion_aux.cpp` (GPU_FusionAux) | Fixed | Already clean against current source — uses `ConvDescGuard` plus stack-allocated internal C++ objects (`miopen::TensorDescriptor`, `miopen::FusionPlanDescriptor`) which have proper destructors. The `convoOp` handle is owned by the fusion plan. ASAN run on `*GPU_FusionAux*` reports no leaks. | | `test/gtest/backend_api.cpp` (CPU_BackendApi) | Skipped | File no longer exists in the codebase. The backend API test infrastructure (part of the removed GraphApi suite) was removed; no fix possible against the current source tree. | ### High-level notes New shared infrastructure (test/gtest/gtest_desc_guard.hpp) - DescGuard<DescType, CreateFn, DestroyFn> — a single RAII template parameterized on the descriptor type and its create/destroy entry points. Aliases provide TensorDescGuard, ConvDescGuard, DropoutDescGuard, and RNNDescGuard, replacing the four near-identical guard structs that were copy-pasted across test files in the initial implementation. - HandleGuard — separate RAII wrapper for miopenHandle_t (couldn't reuse the template because miopenCreateWithStream takes an extra hipStream_t argument). Supports lazy create(stream) so callers that only need a handle in the dropout branch can default-construct one and populate it conditionally. - DestroyInternalRnnDropoutDesc(rnnDesc) — frees the internal DropoutDescriptor that miopenCreateRNNDescriptor allocates and that miopenSetRNNDescriptor* then orphans. Replaces the equivalent inline blocks that LSTM/GRU/RNN tests were each carrying. The header documents the two call-sites: before each Set* (always safe) and at end-of-run only on the non-dropout path (the dropout path aliases the user-owned descriptor, so freeing would double-free). Recurring patterns enabled by the refactor - The "leak from Set* overwriting the default-constructed internal dropout descriptor" fix collapsed from per-file code to a one-line helper call, applied uniformly across lstm.hpp, gru_test.cpp, rnn_seq_api.hpp, and rnn_vanilla_common.hpp. - mio_handle ownership in LSTM/GRU is now expressed via HandleGuard rather than a manual miopenDestroy at the end of the dropout branch — eliminates a class of forgotten-cleanup bugs. - dropout_state_buf is consistently hoisted out of the dropout if block so an end-of-run hipFree can release it; deletion of the buffer pairs visibly with its allocation. Notable non-RNN change - softmax_find20.cpp was the only Find2.0 leak fix in this commit: Finalize() now takes the solutions vector and calls miopenDestroySolution() for each before destroying the problem. Same shape applied to all 6 tests in the file. ## Test Plan Run the tests beforehand to observe the ASan leak errors and then again afterward to verify the fixes have resolved the problem. ## Test Result List from ROCM-21512: | #

# Add gfx950 MXFP4 Subtile-based kernel implementation ## Summary This PR is a follow-up to #6499 ([hipblaslt] Add support for gfx950 mxfp4) and adds the **Subtile-based kernel implementation (`UseSubtileImpl=1`)** for hipBLASLt on **gfx950**. It introduces a new tile-decomposed code generation path optimized for **MXFP4** and **BF16** GEMMs, plus the solution-selection plumbing, validation, Origami logic yamls, and unit tests needed to make it production-usable. ## Motivation PR #6499 brought MX data type support online for gfx950, but the existing TensileLite codegen path leaves significant performance on the table for MXFP4-heavy workloads. The Subtile path restructures global-read / local-read / MFMA / store scheduling at a finer granularity, which **greatly improves MXFP4 GEMM performance when using `HIPBLASLT_MATMUL_MATRIX_SCALE_BLK32_UE8M0_32_8_EXT`** (added to the hipBLASLt CHANGELOG). ## What's included ### 1. New Subtile-based kernel components (Tensile) New modules under `projects/hipblaslt/tensilelite/Tensile/Components/`: * `SubtileBasedKernel.py` (~1850 LOC) — entry point and orchestration of the subtile codegen path; replaces large portions of the standard prefetch / unroll / store flow when `UseSubtileImpl=1`. * `SubtileBasedLogicalScheduler.py` (~2415 LOC) — logical scheduler that builds the subtile-grained instruction graph (GR loads, LR offsets, MFMA tiles, scale loads, stores) from kernel parameters. * `SubtileBasedInstructionScheduler.py` (~433 LOC) — converts the logical schedule to an emit order respecting wave / register / hazard constraints. * `SubtileBasedInstructionEmitter.py` (~216 LOC) — instruction emission helpers shared by the subtile components. ### 2. Kernel writer / common changes * **`KernelWriter.py`**, **`KernelWriterAssembly.py`**: integration points for the subtile path — prefetch, GR offset calculation, LR offset calculation, post-loop, MFMA macro accounting, optimized `storeD`, LDS buffer swap, MX FP4 scale emit, `SrdMXSA/B+2` handling, sgpr allocation / overflow guards, computeLoadSrd fix. * **`SolutionStructs/Solution.py`**, **`SolutionStructs/Problem.py`**: introduces the `UseSubtileImpl` parameter, MX-related reject conditions for non-Subtile paths on gfx950, and additional valid GEMM type combinations for MX inputs. * **`Common/ValidParameters.py`**, **`Common/RequiredParameters.py`**, **`Common/GlobalParameters.py`**: `UseSubtileImpl` registration and defaults. * **`Components/StreamK.py`**: subtile-aware StreamK fixup (incl. import union with the `BufferLoadB32` cache-coherence change from #6837). * **`Components/GlobalWriteBatch.py`**: optimized global write batching for the subtile path (~670 LOC of changes). * **`Components/ComputeStoreVgprs.py`**, **`Components/LSU.py`**, **`Components/WorkGroupMappingAlgos.py`**, **`AsmStoreState.py`**, **`KernelWriterModules.py`**: minor adjustments needed by the subtile pipeline. ### 3. rocisa / host / client * **`rocisa/rocisa/include/container.hpp`**: helpers needed by the new emitter. * **`tensile_host.cpp`**, **`include/Tensile/TensorDescriptor.hpp`**: small fixups for the subtile path and gfx950 build. * **`client/include/DataInitialization.hpp`**, **`client/src/DataInitialization.cpp`**, **`client/src/Reference.cpp`**, **`client/src/ReferenceValidator.cpp`**, **`client/include/TypedId.hpp`**: MX scale init and reference paths used by the new tests. * **`clients/common/include/testing_matmul.hpp`**, **`clients/common/include/norm.hpp`**, **`clients/common/include/hipblaslt_datatype2string.hpp`**, **`clients/common/src/mxDataGen.cpp`**: wiring for batched (>1) testing and MX init. ### 4. Origami / solution selection (gfx950 MXFP4) New auto-tuned logic yamls under `projects/hipblaslt/library/.../Tensile/Logic/asm_full/gfx950/gfx950/Origami/` covering the FP4 SS / HS / BS variants in three layouts: * `Origami/` (default) * `Origami/Origami_nta4/` (no-transpose-A FP4) * `Origami/Origami_ntb4/` (no-transpose-B FP4) (9 new `gfx950_Cijk_Alik_Bljk_F4{SS,HS,BS}_MXA32_MXB32_*_UserArgs.yaml` files in total.) ### 5. New tests **End-to-end gfx950 GEMM yamls** in `Tensile/Tests/common/gemm/gfx950/`: * `subtile_bf16.yaml`, `subtile_mxfp4.yaml` * `mx32f4_tn.yaml`, `mx32f8_tn.yaml` * `mxfp4_mxfp4_{fp32,bf16}_tn_act{,_groupgemm}.yaml` * `mxfp4_fp8_{fp32,bf16}_tn_act{,_groupgemm}.yaml` * `fp8_mxfp4_{fp32,bf16}_tn_act{,_groupgemm}.yaml` **StreamK + MX:** `Tensile/Tests/common/streamk/sk_mx32f4_quick.yaml`, `sk_mx32f8_quick.yaml`. **New unit tests** (`Tensile/Tests/unit/`): * `test_SubtileBasedLogicalScheduler.py` (~1735 LOC) * `test_SubtileBasedSchedulerRef.py` (~596 LOC) * `test_gr_lr_roundtrip.py` (~571 LOC) * `test_storeD_roundtrip.py` (~2420 LOC) * `test_graTileAssignment.py` (~354 LOC) * `test_lraTileAssignment.py` (~360 LOC) * `conftest.py`, `gpu_test_helpers.py` shared fixtures (~601 LOC) **New gtest:** `tensilelite/tests/MXScalePadding_test.cpp`. ### 6. Misc / hardening * Reject conditions: gfx950 MX + non-Subtile, DepthU constraints, GroupGEMM not yet supported with StreamK + MX, AssertSummationElementMultiple=256 for subtile MXFP4, missing-mxblock check for non-MX types. * Skip rocRoller for FP4-A/FP4-B with pre-swizzled scale layout (#42). * `forceDenorm=False` in `generateMXInput` (#11). * Several rebase fixes, copyright/year header updates, and review-comment fixes to `KernelWriter` / `KernelWriterAssembly`. ### 7. CHANGELOG Greatly improved MXFP4 GEMM performance when using HIPBLASLT_MATMUL_MATRIX_SCALE_BLK32_UE8M0_32_8_EXT ## How to use Set `UseSubtileImpl: 1` on a gfx950 MX-FP4 solution (see the new `subtile_mxfp4.yaml` / `mx32f4_tn.yaml` for canonical configs). The path is opt-in — non-MX and non-gfx950 kernels are unaffected. ## Backwards compatibility / risk * All new behavior is gated on `UseSubtileImpl=1` and gfx950. Existing solutions on other architectures or non-MX paths are unchanged. * `GroupGEMM + StreamK + MX` is intentionally rejected for now (TODO). * New Origami yamls only add solutions; nothing existing is modified. ## Test plan * New gtests + unit tests run automatically in CI (Tensilelite Python unit suite, `MXDataGen_test`, `MXScalePadding_test`). * New end-to-end gfx950 GEMM and StreamK yamls are added to the common test buckets. * Manual: run the gfx950 MXFP4 subtile suites (`pytest -k gfx950` after building Tensile, plus `tensilelite-client --yaml subtile_mxfp4.yaml` for sanity). ## Notes for reviewers * This branch was rebased onto current `develop` (post-#6499) by skipping the `users/nakajee/gfx950_mx_rebase_merge` history (which #6499 squash-merged) and replaying only the subtile-specific work as a single squashed commit. The actual code changes in this PR are limited to the files listed above (24 added, 56 modified; ~+170k / −2.6k including generated logic yamls). * The largest reviewable diffs are: * `Tensile/Components/SubtileBased{Kernel,LogicalScheduler,InstructionScheduler,InstructionEmitter}.py` (new files) * `Tensile/KernelWriter.py`, `Tensile/KernelWriterAssembly.py` * `Tensile/SolutionStructs/{Problem,Solution}.py` * `Tensile/Components/{GlobalWriteBatch,StreamK}.py` * `clients/common/include/testing_matmul.hpp` * `client/src/DataInitialization.cpp` * Description of all commits that were squashed for this feature branch: Subtile implementation for gfx950 MX FP4 --- 272f88d: Add sample subtile impl --- Author: brianshi <brianshi@amd.com> --- 60ecede: GR Offset calculation (#1) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- be69c1d: Enable post-loop code generation, and add some subroutines --- Author: b-shi <brianshi@amd.com> --- 646d102: LR offset calculation (#2) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- 71f4bca: Add GR load emit logic, and misc fixes (#3) --- Author: b-shi <brianshi@amd.com> --- 1fd0db9: Emit LR + init ACCVGPR (#4) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- 9d406b9: Add loop and ptr update code --- Author: b-shi <brianshi@amd.com> --- b6127bc: Update GR/LR offset calculation to fully support 2x2, 1x4, 4x1 waveConfigs (#7) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- 89ec87c: Account for valuC macro value in SK WS store code --- Author: b-shi <brianshi@amd.com> --- 6edf53d: Rebase fix --- Author: b-shi <brianshi@amd.com> --- 34e79fc: Enable fp4 (#8) --- Author: sebvince <115461989+sebvince@users.noreply.github.com> --- d5a5c57: [Tensilelite] Add MX FP4 scale offset computation for subtile-based kernel (#6) --- Author: Archana Ramalingam <98564406+archana-ramalingam@users.noreply.github.com> --- 7a8a85a: Add lds buffer swap logic --- Author: b-shi <brianshi@amd.com> --- d24a8fe: Add optimized storeD code (#9) --- Author: b-shi <brianshi@amd.com> --- a45c20c: Fix MX scale tensor initialization: set forceDenorm=false in generateMXInput (#11) --- Author: T.J.

…7008) ## Motivation Several memory leaks were detected in MIOpen gtests using ASan. Some of the tests were blacklisted and others were not. This change looks to fix all of the low hanging fruit, which are the majority of the leaks found. This includes all of the critical leaks (>100MB) that were reported. Some other leaks were identified as needing a larger refactor to resolve. After fixing the w_supertensor.cpp leak, the supertensor tests hit virtual memory area limit errors. These changes are to enable running them with ASan, but only with a subset of the tests in order to not hit limits. The test coverage being lost is fairly negligible and the full tests are still run without ASan enabled. ## Technical Details Here is a summary of the files looked at and the changes made: | File | Status | Notes | |------|--------|-------| | `test/gtest/gpu_mha_forward.cpp` | Fixed | Added `miopenDestroySolution()` loop after using solutions. Fixes MHA forward solution descriptor leaks (report #11, #13). | | `test/gtest/gpu_mha_backward.cpp` | Fixed | Added `miopenDestroySolution()` loop after using solutions. Fixes MHA backward solution descriptor leaks (report #9, #12). | | `test/gtest/mha_find20.cpp` | Fixed | Added `miopenDestroySolution()` loop in both `MhaForward` and `MhaBackward` tests. Fixes MHA Find2.0 solution leak (report #16). | | `test/gtest/gtest_desc_guard.hpp` | Fixed | New shared header introduced by the refactor. Provides a single `DescGuard<DescType, CreateFn, DestroyFn>` template (with `TensorDescGuard`, `ConvDescGuard`, `DropoutDescGuard`, `RNNDescGuard` aliases), a `HandleGuard` RAII wrapper for `miopenHandle_t`, and the `DestroyInternalRnnDropoutDesc(rnnDesc)` helper used by every RNN/LSTM/GRU test to free the internal `DropoutDescriptor` that `miopenCreateRNNDescriptor` allocates and `miopenSetRNNDescriptor*` then leaks. Replaces the per-file ad-hoc guard structs from the initial implementation. | | `test/gtest/w_supertensor.cpp` | Fixed | Switched raw descriptors to the shared `RNNDescGuard` / `TensorDescGuard` from `gtest_desc_guard.hpp`. Added a class-local `DestroyDropoutDesc()` (called from `TearDown` and before `miopenSetRNNDescriptor`) to prevent the `miopenSetRNNDescriptor` overwrite leak. Reduced test parameter space under ASan to avoid OOM. Removed unused `seqLen` parameter and dead `param_dev_out`/`bias_dev_out` allocations. | | `test/gtest/lstm.hpp` | Fixed | Switched `rnnDesc` → `RNNDescGuard`, `DropoutDesc` → `DropoutDescGuard`, and `mio_handle` → `HandleGuard` (which now owns the `miopenDestroy` call), all from the shared `gtest_desc_guard.hpp`. Hoisted `dropout_state_buf` so it can be `hipFree`d at the end of the dropout path. Added `DestroyInternalRnnDropoutDesc(rnnDesc)` before `miopenSetRNNDescriptor*` and (in the non-dropout path only) at end of `Run`, which frees the internal `DropoutDescriptor` that the Set call would otherwise leak. Fixes ~615 MB dropout leaks and ~16.5 KB non-dropout descriptor leaks (report #3, #4, #6, #17-#22). | | `test/gtest/gru_test.cpp` | Fixed | In the GRU test class: switched `rnnDesc` → `RNNDescGuard`, `DropoutDesc` → `DropoutDescGuard`, `mio_handle` → `HandleGuard`, and added `DestroyInternalRnnDropoutDesc(rnnDesc)` before `miopenSetRNNDescriptor*` and (non-dropout path only) at end of `Run` plus `hipFree(dropout_state_buf)` for the dropout path. In the in-file `GRUFwdCPUVerify` / `GRUBwdDataCPUVerify` helpers: converted the raw `dropout_inputTensor` / `dropout_outputTensor` declarations to `TensorDescGuard` (mirroring the `cpu_rnn.hpp` change for the LSTM/RNN helpers). | | `test/gtest/softmax_find20.cpp` | Fixed | Changed `Finalize()` to take the `std::vector<miopenSolution_t>&` and destroy each solution via `miopenDestroySolution()` before destroying the problem. Updated all 6 `TEST(...)` callers to pass the solutions vector. Fixes Find2.0 softmax solution/kernel leaks (report #25-#27). | | `test/gtest/rnn_seq_api.hpp` | Fixed | Hoisted `dropout_state_buf` so the dropout path can `hipFree` it at the end. Added `DestroyInternalRnnDropoutDesc(&rnnDesc)` before `miopenSetRNNDescriptor*` and (non-dropout path only) at end of the run to free the internal `DropoutDescriptor` allocations leaked by `RNNDescriptor` copy-assignment. Same pattern as the LSTM/GRU fixes (report #29-#30). | | `test/cpu_rnn.hpp` | Fixed | Converted 6 raw `miopenTensorDescriptor_t dropout_input/outputTensor` declarations across the LSTM/RNN CPU verification helpers (`LSTMFwdCPUVerify`, `LSTMBwdDataCPUVerify`, `RNNFwdTrainCPUVerify`, `RNNBwdDataCPUVerify`, `GRUFwdCPUVerify`, `GRUBwdDataCPUVerify`) to the shared `TensorDescGuard` from `gtest_desc_guard.hpp`. Removed the redundant `miopenCreateTensorDescriptor` calls and updated 12 `miopen::deref(...)` sites to `.get()`. (Note: the GRU helpers in this header are stale duplicates; the live ones are inside `test/gtest/gru_test.cpp` and were updated there too.) Fixes the LSTM/GRU CPU-verify tensor descriptor leaks (report #1, #2, #14, #15, #32, #33). | | `test/gtest/rnn_vanilla_common.hpp` | Fixed | Added `DestroyInternalRnnDropoutDesc(rnnDesc)` calls before `miopenSetRNNDescriptor*` and (non-dropout path only) at end of the run. The `RNNDescGuard` / `DropoutDescGuard` usage was already in place from an earlier commit and now resolves to the shared definitions in `gtest_desc_guard.hpp`. Same pattern as LSTM/GRU/rnn_seq_api fixes (report #14, #15, #32, #33). | | `test/gtest/graphapi_gtest_common.hpp` | Skipped | File no longer exists in the codebase. The GraphApi test infrastructure has been removed; only the leak report (a stale snapshot) still references it. No fix possible against the current source tree. | | `test/gtest/graphapi_execution_plan.cpp` | Skipped | File no longer exists in the codebase (GraphApi removed). The leak it represented was largely an external hipblaslt bug anyway; the remaining test-side portion is not fixable against the current source. | | `test/gtest/na_train.cpp` / `na_inference.cpp` / `na_*_find2.cpp` | Skipped | Leaks come from the internal MIOpen solver/kernel cache living on the global singleton handle, which is never destroyed. Not easily fixable without redesigning global handle lifecycle. Should be suppressed in the ASan suppression file. | | hipblaslt / rocblaslt (external) | Skipped | `SolutionCache::addKernel` and `preloadCustomKernels` leak via `_rocblaslt_handle` constructor. Called from `miopen::Handle::CreateHipblasLtHandle`. This is an upstream bug in hipblaslt/rocblaslt, not fixable in MIOpen. Affects suites that initialize a handle (report Category 2, Category 7). | | CLR / HIP runtime (external) | Skipped | `amd::Context` and `amd::roc::Device` global initialization leaks from `rocclr/platform/context.cpp`. HIP runtime internals, not fixable in MIOpen. | | `src/hipoc/hipoc_program.cpp` | Skipped | `HIPOCProgramImpl` objects leak during kernel compilation/caching (line ~178). This is an internal MIOpen kernel cache lifecycle issue that requires deeper architectural changes to fix. Contributes small amounts to MHA and Softmax Find2.0 leaks. | | `test/gtest/conv_api.cpp` | Fixed | Already clean against current source — `miopenDestroyConvolutionDescriptor(conv_desc)` call exists (line 24) inside the test loop. ASAN run reports no leaks. The leak report was based on a stale snapshot. The hipblaslt handle init portion is tracked under the external-skipped row. | | `test/gtest/log_test.cpp` (CPU_LOG_TEST_FUSION / CPU_LOG_TEST_NEG) | Fixed | Already clean against current source — `Tensor`, `Conv`, `CreateCBAFusionPlan`, `CreateBNormFusionPlan` all have proper destructors that call the corresponding `miopenDestroy*` APIs in `log.cpp`. ASAN run on `CPU_LOG_TEST_*` (11 tests across log_test.cpp + log_test_neg.cpp) reports no leaks. The hipblaslt handle init portion is tracked separately under the external-skipped row. | | `test/gtest/fusion_test.cpp` (CPU_FusionCreateOpConvForward) | Fixed | File renamed from `fusion.cpp` to `fusion_test.cpp`. Already clean against current source — uses `TensorDescGuard`/`ConvDescGuard` for tensor/conv descriptors and calls `miopenDestroyFusionPlan(fusionPlanDesc)` on the fusion plan (line 195). ASAN run on `CPU_FusionCreateOpConvForward_FP32.*` reports no leaks. | | `test/gtest/deterministic_conv_api.cpp` | Fixed | Already clean against current source — uses `ConvDescGuard` (line 66) for the conv descriptor. ASAN run on `*CPU_DeterministicConvApi*` reports no leaks. | | `test/gtest/fusion_aux.cpp` (GPU_FusionAux) | Fixed | Already clean against current source — uses `ConvDescGuard` plus stack-allocated internal C++ objects (`miopen::TensorDescriptor`, `miopen::FusionPlanDescriptor`) which have proper destructors. The `convoOp` handle is owned by the fusion plan. ASAN run on `*GPU_FusionAux*` reports no leaks. | | `test/gtest/backend_api.cpp` (CPU_BackendApi) | Skipped | File no longer exists in the codebase. The backend API test infrastructure (part of the removed GraphApi suite) was removed; no fix possible against the current source tree. | ### High-level notes New shared infrastructure (test/gtest/gtest_desc_guard.hpp) - DescGuard<DescType, CreateFn, DestroyFn> — a single RAII template parameterized on the descriptor type and its create/destroy entry points. Aliases provide TensorDescGuard, ConvDescGuard, DropoutDescGuard, and RNNDescGuard, replacing the four near-identical guard structs that were copy-pasted across test files in the initial implementation. - HandleGuard — separate RAII wrapper for miopenHandle_t (couldn't reuse the template because miopenCreateWithStream takes an extra hipStream_t argument). Supports lazy create(stream) so callers that only need a handle in the dropout branch can default-construct one and populate it conditionally. - DestroyInternalRnnDropoutDesc(rnnDesc) — frees the internal DropoutDescriptor that miopenCreateRNNDescriptor allocates and that miopenSetRNNDescriptor* then orphans. Replaces the equivalent inline blocks that LSTM/GRU/RNN tests were each carrying. The header documents the two call-sites: before each Set* (always safe) and at end-of-run only on the non-dropout path (the dropout path aliases the user-owned descriptor, so freeing would double-free). Recurring patterns enabled by the refactor - The "leak from Set* overwriting the default-constructed internal dropout descriptor" fix collapsed from per-file code to a one-line helper call, applied uniformly across lstm.hpp, gru_test.cpp, rnn_seq_api.hpp, and rnn_vanilla_common.hpp. - mio_handle ownership in LSTM/GRU is now expressed via HandleGuard rather than a manual miopenDestroy at the end of the dropout branch — eliminates a class of forgotten-cleanup bugs. - dropout_state_buf is consistently hoisted out of the dropout if block so an end-of-run hipFree can release it; deletion of the buffer pairs visibly with its allocation. Notable non-RNN change - softmax_find20.cpp was the only Find2.0 leak fix in this commit: Finalize() now takes the solutions vector and calls miopenDestroySolution() for each before destroying the problem. Same shape applied to all 6 tests in the file. ## Test Plan Run the tests beforehand to observe the ASan leak errors and then again afterward to verify the fixes have resolved the problem. ## Test Result List from ROCM-21512: | #
