(#19636) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is done for conv, depthwise conv, transpose conv, and bmm. Add scratch tensors to the operator signatures, which are then assigned exir.memory.alloc. These allocs are automatically memory planned by ExecuTorch. Introduce `required_cmsis_buffer_size`which computes the buffer size from node properties + the Cortex-M configuration. The function uses functions registered by target in backends/cortex_m/passes/scratch_buffer_sizes.py This is used to set the size of the allocs in ConvertToCortexMPass Finally, modify the kernels to use the new scratch tensor instead of allocating temporary memory. Add a new macro CORTEX_M_ENABLE_RUNTIME_CHECKS to do a safety check that the aot computed buffer size is equal to the buffer size computed at runtime. Use this when testing. cc @psiddh @AdrianLundell @digantdesai @rascani @freddan80 @per @zingo @oscarandersson8218 @mansnils @Sebastian-Larsson @robell --------- Signed-off-by: Erik Lundell Co-authored-by: Måns Nilsson --- backends/arm/scripts/build_executorch.sh | 8 + backends/cortex_m/CMakeLists.txt | 9 + .../ops/op_quantized_batch_matmul.cpp | 35 +-- backends/cortex_m/ops/op_quantized_conv2d.cpp | 34 +-- .../ops/op_quantized_depthwise_conv2d.cpp | 31 +- .../ops/op_quantized_transpose_conv2d.cpp | 44 +-- backends/cortex_m/ops/operators.py | 28 +- backends/cortex_m/ops/operators.yaml | 9 +- backends/cortex_m/passes/__init__.py | 1 + .../passes/convert_to_cortex_m_pass.py | 64 ++++- .../cortex_m/passes/scratch_buffer_sizes.py | 266 ++++++++++++++++++ backends/cortex_m/test/build_test_runner.sh | 4 +- 12 files changed, 451 insertions(+), 82 deletions(-) create mode 100644 backends/cortex_m/passes/scratch_buffer_sizes.py diff --git a/backends/arm/scripts/build_executorch.sh b/backends/arm/scripts/build_executorch.sh index 54d2091d1f4..5ac2674f964 100755 --- a/backends/arm/scripts/build_executorch.sh +++ b/backends/arm/scripts/build_executorch.sh @@ -7,6 +7,7 @@ # Optional parameter: # --build_type= "Release" | "Debug" | "RelWithDebInfo" | "UndefinedSanitizer" | "AddressSanitizer" # --etdump build with devtools-etdump support +# --cmake-args= Additional arguments passed to cmake configure set -eu @@ -24,6 +25,7 @@ build_type="Release" build_devtools=OFF build_with_etdump=OFF is_linux_musl=0 +extra_cmake_args=() target_cpu="" help() { @@ -33,6 +35,7 @@ help() { echo " --build_type= Build with Release, Debug, RelWithDebInfo, UndefinedSanitizer or AddressSanitizer, default is ${build_type}" echo " --devtools Build Devtools libs" echo " --etdump Adds Devtools etdump support to track timing, etdump area will be base64 encoded in the log" + echo " --cmake-args= Additional arguments passed to cmake configure" echo " --toolchain= Toolchain can be specified (arm-none-eabi-gcc, arm-zephyr-eabi-gcc, aarch64-linux-musl-gcc).

This PR focuses on removing the hardcode dtype for them. #### Key changes - Remove template parameter from KVManager, LhdTokenGenerator, MultimodalPromptProcessor, and related runner classes - Detect kv_cache and attention_mask dtypes dynamically from MethodMeta at construction time instead of compile-time bitwidth detection - Switch to std::byte* pointer arithmetic with getDtypeSize() for all buffer offsets; add fill_mask() helper for multi-dtype attention mask filling - Update spec_prop pass for custom llama op for sharding case greater than 1 ### Test plan ``` python

The Cortex-M kernels are registered through generated wrappers, so cppcheck cannot see direct call sites for the exported *_out entry points and reports them as unused. Keep narrow unusedFunction suppressions for those registration-visible functions. The scratch buffer context header is linted as a standalone header but currently exposes helper API without in-tree call sites, so suppress unusedFunction at file scope there instead of dropping Cortex-M header coverage. Keep the quantize and dequantize context parameters non-const to match the generated kernel ABI; changing them to const changes the mangled symbols used by registration.

It doesn't add Yolo on baremetal, but it at least makes sure that it works using Portable Kernels and XNNPACK backends. ### Test plan It's only adding a model to CI, so the CI is the test plan. --- .github/workflows/riscv64.yml | 31 ++++++++++++++++--------------- examples/riscv/aot_riscv.py | 33 +++++++++++++++++++++++++++++++++ examples/riscv/requirements.txt | 1 + examples/riscv/setup.sh | 5 ++++- 4 files changed, 54 insertions(+), 16 deletions(-) diff --git a/.github/workflows/riscv64.yml b/.github/workflows/riscv64.yml index 14b9ad62047..a7a5273e2b0 100644 --- a/.github/workflows/riscv64.yml +++ b/.github/workflows/riscv64.yml @@ -28,21 +28,22 @@ jobs: strategy: fail-fast: false matrix: - include: - - { model: add, xnnpack: false, quantize: false } - - { model: add, xnnpack: true, quantize: false } - - { model: mv2, xnnpack: false, quantize: false } - - { model: mv2, xnnpack: true, quantize: false } - - { model: mv2, xnnpack: true, quantize: true } - - { model: mobilebert, xnnpack: false, quantize: false } - - { model: mobilebert, xnnpack: true, quantize: false } - - { model: mobilebert, xnnpack: true, quantize: true } - - { model: llama2, xnnpack: false, quantize: false } - - { model: llama2, xnnpack: true, quantize: false } - - { model: llama2, xnnpack: true, quantize: true } - - { model: resnet18, xnnpack: false, quantize: false } - - { model: resnet18, xnnpack: true, quantize: false } - - { model: resnet18, xnnpack: true, quantize: true } + model: + - add + - mv2 + - mobilebert + - llama2 + - resnet18 + - yolo26 + xnnpack: [true, false] + quantize: [true, false] + exclude: + # We only enable quantization with XNNPACK + - xnnpack: false + quantize: true + # We don't test quantization for Yolo26 + - model: yolo26 + quantize: true permissions: id-token: write contents: read diff --git a/examples/riscv/aot_riscv.py b/examples/riscv/aot_riscv.py index 529e2b1e767..edc30c2653b 100644 --- a/examples/riscv/aot_riscv.py +++ b/examples/riscv/aot_riscv.py @@ -114,12 +114,45 @@ def build_resnet18(): return model, example_inputs, test_inputs, False +def build_yolo26(): + # Mirrors examples/models/yolo26/export_and_validate.py: predict() once + # to materialise the predictor state Ultralytics expects pre-export. + import numpy as np + from ultralytics import YOLO + + input_h, input_w = 320, 320 + yolo = YOLO("yolo26n") + yolo.predict( + np.ones((input_h, input_w, 3)), + imgsz=(input_h, input_w), + device="cpu", + ) + + class Wrapper(torch.nn.Module): + def __init__(self): + super().__init__() + self.model = yolo.model.to(torch.device("cpu")).eval() + + def forward(self, x): + # yolo.model emits (predictions, feature_maps) in eval; keep the + # predictions tensor so BundledIO sees a single tensor output. + out = self.model(x) + return out[0] if isinstance(out, (tuple, list)) else out + + model = Wrapper().eval() + torch.manual_seed(0) + example_inputs = (torch.randn(1, 3, input_h, input_w),) + test_inputs = [example_inputs] + return model, example_inputs, test_inputs, False + + MODELS = { "add": build_add, "mv2": build_mv2, "mobilebert": build_mobilebert, "llama2": build_llama2, "resnet18": build_resnet18, + "yolo26": build_yolo26, } diff --git a/examples/riscv/requirements.txt b/examples/riscv/requirements.txt index 273e7156a1d..649696ae65c 100644 --- a/examples/riscv/requirements.txt +++ b/examples/riscv/requirements.txt @@ -1,2 +1,3 @@ torchvision transformers +ultralytics diff --git a/examples/riscv/setup.sh b/examples/riscv/setup.sh index 955c8ca3386..48d5ed27642 100755 --- a/examples/riscv/setup.sh +++ b/examples/riscv/setup.sh @@ -33,7 +33,10 @@ ${SUDO} apt-get install -y --no-install-recommends \ cmake \ file \ ca-certificates \ - qemu-user-static + qemu-user-static \ + libglib2.0-0t64 \ + libxcb1 \ + libgl1 if [[ -n "${GCC_VERSION+x}" ]]; then ${SUDO} update-alternatives --install /usr/bin/riscv64-linux-gnu-gcc riscv64-linux-gnu-gcc /usr/bin/riscv64-linux-gnu-gcc${GCC_VERSION:+-${GCC_VERSION}} 100 From 6128a45130a0e6504c48b8bbdf01259f28ad964c Mon Sep 17 00:00:00 2001 From: Hansong Zhang <107070759+kirklandsign@users.noreply.github.com> Date: Tue, 26 May 2026 09:29:07 -0700 Subject: [PATCH 020/317] Convert minibench Java files to Kotlin (#19760) Convert BenchmarkActivity, BenchmarkMetric, LlmBenchmark, LlmModelRunner, and ModelRunner from Java to Kotlin.

charset=UTF-8 Content-Transfer-Encoding: 8bit ### Summary Extend the Cortex-M cross-CPU build pipeline to Armv6-M by patching two upstream issues that block the Corstone-300 target source and the CMSIS Cortex DFP from building for `cortex-m0plus`: * `core_platform/0003-*.patch` guards the `HardFault_Handler` in `targets/corstone-300/target.cpp`. The handler uses an `ite eq` IT-block in inline asm and dereferences the SCB CFSR/BFAR/MMFAR fault-status registers; both are Armv7-M / Armv8-M Mainline only. The patch wraps the rich handler in `__ARM_ARCH_7M__ / 7EM / 8M_MAIN / 8_1M_MAIN` and falls back to a minimal stub on Armv6-M / Armv8-M Baseline (M0/M0+/M23). * `core_software/0002-*.patch` fixes `cmsis.cmake`'s handling of the M0+ device. The Cortex DFP names the device directory and headers `ARMCM0plus` (lowercase suffix), while the device sources (`startup_ARMCM0plus.c`, `system_ARMCM0plus.c`) gate their implementations on the `ARMCM0P` preprocessor macro — three different spellings. The previous `string(TOUPPER ...)` produced `ARMCM0PLUS`: the include path lookup failed and the source files hit their `#error device not specified!` guard. Override `ARM_CPU` to `ARMCM0plus` for the directory + filename and introduce a separate `CMSIS_DEVICE_CPU_DEFINE` set to `ARMCM0P` for the cmsis_startup and cmsis_system compile-definitions; all other cores still drive both paths from the uppercased default. Both patches are layered via the existing `patch_repo` mechanism; the `corstone_utils.cmake` TODO is updated so the deletion plan for 0002 and 0003 is documented together. ### Test Plan Locally validated end-to-end on the Corstone-300 FVP with the `qadd` model: `cortex-m0plus` build links a runner that includes `startup_ARMCM0plus.c` / `system_ARMCM0plus.c` and the patched `target.cpp`, and the FVP run prints `TEST: BundleIO index[0] Test_result: PASS` with all error stats zero. The bundled `libcmsis-nn.a` reports `Tag_CPU_arch: v6S-M` and `Tag_THUMB_ISA_use: Thumb-1` with zero DSP / MVE / saturating instructions, confirming the scalar code path was exercised.

This package provides Java bindings for running ExecuTorch models on Android. Use these - * classes to load a {@code .pte} model file and run inference directly from your Java or Kotlin - * Android app — no C++ required. - * - *

Quick Start

- * - *

Step 1. Add the dependency to your {@code app/build.gradle.kts}: - * - * 

{@code
- * dependencies {
- *     implementation("org.pytorch:executorch-android:${executorch_version}")
- * }
- * }
- * - *

Step 2. Load your model and run inference: - * - * 

{@code
- * import org.pytorch.executorch.EValue;
- * import org.pytorch.executorch.Module;
- * import org.pytorch.executorch.Tensor;
- *
- * // Load your exported .pte model file
- * Module module = Module.load("/data/local/tmp/model.pte");
- *
- * // Build an input tensor  e.g. a 1x3x224x224 image
- * float[] inputData = new float[1 * 3 * 224 * 224];
- * Tensor inputTensor = Tensor.fromBlob(inputData, new long[]{1, 3, 224, 224});
- *
- * // Run inference
- * EValue[] output = module.forward(EValue.from(inputTensor));
- *
- * // Read the result
- * float[] scores = output[0].toTensor().getDataAsFloatArray();
- * }
- * - *

This was intended to reduce random tolerance flakes, but didn't actually do so in practice. This is because the parallel test runners don't guarantee any ordering, so random state is unstable between runs. I've updated it to set the seed per-test. This should hopefully make the random state invariant of test execution order. --- backends/cadence/aot/tests/test_replace_ops_passes.py | 2 ++ conftest.py | 8 ++++++-- 2 files changed, 8 insertions(+), 2 deletions(-) diff --git a/backends/cadence/aot/tests/test_replace_ops_passes.py b/backends/cadence/aot/tests/test_replace_ops_passes.py index 170da6deb09..a73ef02c996 100644 --- a/backends/cadence/aot/tests/test_replace_ops_passes.py +++ b/backends/cadence/aot/tests/test_replace_ops_passes.py @@ -1250,6 +1250,7 @@ def test_replace_conv1d_with_linear(self) -> None: inputs, "ReplaceTrivialConvWithLinear", rtol=2e-5, + atol=5e-6, ) # Assert that conv1d is trivially converted to linear @@ -1294,6 +1295,7 @@ def test_replace_conv2d_with_linear(self) -> None: inputs, "ReplaceTrivialConvWithLinear", rtol=2e-5, + atol=5e-6, ) # Assert that conv2d is trivially converted to linear diff --git a/conftest.py b/conftest.py index 19d777a74e0..be0e6e4ea3d 100644 --- a/conftest.py +++ b/conftest.py @@ -1,3 +1,4 @@ +import hashlib import sys import torch @@ -13,5 +14,8 @@ "backends/apple/**", ] -# Seed the run -torch.manual_seed(42) + +def pytest_runtest_setup(item): + # Set a stable seed for each test based on a hash of the test name. + seed = int(hashlib.sha256(item.nodeid.encode()).hexdigest(), 16) % (2**32) + torch.manual_seed(seed) From b4d62edb4b1f941e84d9a3d675e2a082bd09c2a6 Mon Sep 17 00:00:00 2001 From: Hansong Zhang <107070759+kirklandsign@users.noreply.github.com> Date: Tue, 26 May 2026 16:24:48 -0700 Subject: [PATCH 028/317] Collapse Experimental.kt annotation onto a single line to satisfy linter Differential Revision: D106430647 Pull Request resolved: https://github.com/pytorch/executorch/pull/19790 --- .../java/org/pytorch/executorch/annotations/Experimental.kt | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/extension/android/executorch_android/src/main/java/org/pytorch/executorch/annotations/Experimental.kt b/extension/android/executorch_android/src/main/java/org/pytorch/executorch/annotations/Experimental.kt index 1a38bb13b99..42a5980d6ba 100644 --- a/extension/android/executorch_android/src/main/java/org/pytorch/executorch/annotations/Experimental.kt +++ b/extension/android/executorch_android/src/main/java/org/pytorch/executorch/annotations/Experimental.kt @@ -15,5 +15,4 @@ package org.pytorch.executorch.annotations * This status is not permanent, and APIs marked with this annotation will need to be either made * more robust or removed in the future. */ -@Retention(AnnotationRetention.BINARY) -annotation class Experimental +@Retention(AnnotationRetention.BINARY) annotation class Experimental From 034b044382d95894eab62f1a258fc2fec6f3a34a Mon Sep 17 00:00:00 2001 From: Ethan Ng Date: Tue, 26 May 2026 17:15:16 -0700 Subject: [PATCH 029/317] Handle out_dtype in ReplacePT2DequantWithCadenceDequantPass (#19743) Differential Revision: D105630451 Pull Request resolved: https://github.com/pytorch/executorch/pull/19743 --- backends/cadence/aot/replace_ops.py | 23 ++++++++++++++++++++--- 1 file changed, 20 insertions(+), 3 deletions(-) diff --git a/backends/cadence/aot/replace_ops.py b/backends/cadence/aot/replace_ops.py index 4b60feb2121..50112a4eb66 100644 --- a/backends/cadence/aot/replace_ops.py +++ b/backends/cadence/aot/replace_ops.py @@ -162,14 +162,31 @@ def targets(self) -> list[EdgeOpOverload]: def maybe_remove_or_replace(self, node: torch.fx.Node) -> bool: ns = exir_ops.edge if isinstance(node.target, EdgeOpOverload) else torch.ops + out_dtype = node.kwargs.get("out_dtype") + kwargs = {k: v for k, v in node.kwargs.items() if k != "out_dtype"} with node.graph.inserting_before(node): new_node = node.graph.call_function( ns.cadence.dequantize_per_tensor.default, args=node.args, - kwargs=node.kwargs, + kwargs=kwargs, ) - new_node.meta = node.meta - node.replace_all_uses_with(new_node) + new_node.meta = node.meta.copy() + if ( + out_dtype is not None + and out_dtype != torch.float32 + and "val" in new_node.meta + ): + new_node.meta["val"] = new_node.meta["val"].to(torch.float32) + if out_dtype is not None and out_dtype != torch.float32: + with node.graph.inserting_after(new_node): + cast_node = node.graph.call_function( + ns.aten.to.dtype, + args=(new_node, out_dtype), + ) + cast_node.meta = node.meta.copy() + node.replace_all_uses_with(cast_node) + else: + node.replace_all_uses_with(new_node) return True From 79fe3a30148d4cebbff9a2f89254469787e74256 Mon Sep 17 00:00:00 2001 From: Daisuke Majima Date: Wed, 27 May 2026 09:25:09 +0900 Subject: [PATCH 030/317] Add coreml_compute_plan.py: report which CoreML ops dispatch to ANE / GPU / CPU (#19252) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ### Summary CoreML decides at compile/load time which device each MIL operation will execute on, and coremltools 9.0+ exposes that through `MLComputePlan`. The recurring question on the issue tracker is *"why isn't my model running fully on the ANE?"* — for example: - #4091 — `llama model is not fully lowered to ANE` - #11541 — `CoreML model is crashing on iPhone GPU, but not on iPhone CPU or macOS GPU` - #8439 — `ANE compile OOMs on certain input shapes` - #8445 — `CPU Overhead After ANE Execution` Today the only way for an ExecuTorch user to answer it is to break out Swift / Xcode. This PR adds a Python wrapper around `MLComputePlan` so the answer is one shell command: ``` $ python coreml_compute_plan.py --model_path my_model.mlpackage \ --compute_units cpu_and_ne --show_non_ane === my_model.mlpackage === ANE: 412 / 480 ( 85.8%) CPU: 68 / 480 ( 14.2%) Non-ANE op types: 32 ios17.cast 18 ios17.gather 12 ios17.reshape 6 ios17.constexpr_blockwise_shift_scale ``` Inputs supported: | Input | Behavior | |---|---| | `.pte` | Extract every Core ML partition into a tempdir, then analyze each. | | `.mlpackage` | Compile to `.mlmodelc` in a tempdir, then analyze. | | `.mlmodelc` | Analyze directly. | The PTE path reuses the same JSON/named-data extraction logic that `extract_coreml_models.py` uses, and is inlined into the script so it can be run against a plain CoreML model without depending on the executorch package. ### Test plan Added `test_coreml_compute_plan.py` covering: - `_device_name(...)` for `None` and a stub `MLNeuralEngineComputeDevice`. - `_COMPUTE_UNIT_CHOICES` mapping (`cpu_and_ne` / `all`). - `analyze_one(...)` end-to-end on a tiny `relu(x @ x.T) + x.sum()` mlpackage built with `coremltools.convert(...)`: returns rows for every dispatched op, with a `main` function and the expected MIL op types (`matmul`, `relu`, `add`, `reduce_sum`). ``` $ python -m pytest examples/apple/coreml/scripts/test_coreml_compute_plan.py -v ============================== 7 passed in 3.68s =============================== ``` I also ran the script against a few hand-built `.mlpackage` and `.mlmodelc` files on macOS 26 with coremltools 9.0 and verified the output matches what `MLComputePlan` returns directly.

This removes duplicate shape constants. This improvement is model dependent. Models with few repeated literal shapes will not see any meaningful change, but some models can benefit from it notably.

When the macro is invoked at function scope and again inside a nested block in the same function (for example `Program::load` invokes it at the top of the function and then again inside `check_header` / `verify_internal_consistency` blocks), `-Wshadow` fires and the build fails. Fixed by token-pasting `__LINE__` so each invocation gets a unique identifier. No caller changes required. 2. `to_string(Error)` in `runtime/core/error.h` is a switch statement covering every enum value with a trailing `return "Error::Unknown"` fallback after the switch. Apple's toolchain promotes `-Wswitch-default` to an error and rejects switches that lack an explicit `default:` arm. Folded the trailing fallback into a `default:` arm inside the switch. Both issues only surfaced under the Apple toolchain; fbcode toolchain does not promote these warnings to errors, so devserver / Linux builds continued to pass.

That path is already supported through CloneDimOrderConfig. Some XNNPACK export flows use skip_dim_order=True, where aten.clone.default stays as aten.clone.default and is not selected by the partitioner. Adds CloneConfig for dim-order-preserving aten.clone.default nodes so this path is partitioned directly. This reduces delegate splits in the EdgeTAM mask decoder, where profiling exports use skip_dim_order=True. cc @digantdesai @freddan80 @per @zingo @oscarandersson8218 @Sebastian-Larsson @robell @rascani Signed-off-by: Måns Nilsson --- backends/xnnpack/operators/op_clone.py | 19 +++++++++--- backends/xnnpack/partition/config/__init__.py | 3 ++ .../partition/config/generic_node_configs.py | 21 +++++++++++++ backends/xnnpack/test/ops/test_clone.py | 30 ++++++++++++++++++- 4 files changed, 68 insertions(+), 5 deletions(-) diff --git a/backends/xnnpack/operators/op_clone.py b/backends/xnnpack/operators/op_clone.py index e4ddf187ecc..c36d750148c 100644 --- a/backends/xnnpack/operators/op_clone.py +++ b/backends/xnnpack/operators/op_clone.py @@ -1,5 +1,6 @@ # Copyright (c) Meta Platforms, Inc. and affiliates. # All rights reserved. +# Copyright 2026 Arm Limited and/or its affiliates. # # This source code is licensed under the BSD-style license found in the # LICENSE file in the root directory of this source tree. @@ -13,6 +14,7 @@ NodeVisitor, register_node_visitor, ) +from executorch.backends.xnnpack.operators.quant_params import QuantParams from executorch.backends.xnnpack.serialization.xnnpack_graph_schema import ( XNNCopy, XNNGraph, @@ -25,9 +27,6 @@ class CloneVisitor(NodeVisitor): target = "aten.clone.default" - def __init__(self, *args) -> None: - super().__init__(*args) - def define_node( self, node: torch.fx.Node, @@ -35,7 +34,19 @@ def define_node( vals_to_ids: Dict[torch.fx.Node, int], debug_handle: int, ) -> None: - self.define_nodes_tensor_inputs_outputs(node, xnn_graph, vals_to_ids) + self.define_tensor( + node, + xnn_graph, + vals_to_ids, + quant_params=QuantParams.from_outputs(node), + ) + input_node = get_input_node(node, 0) + self.define_tensor( + input_node, + xnn_graph, + vals_to_ids, + quant_params=QuantParams.from_inputs(input_node, self._exported_program), + ) # Sanity check that the input and output dim order are the same.

ConstraintBasedSymShapeEvalPass concretizes TensorSpec metadata, but ToOutVarPass was still building memory.alloc nodes from symbolic FakeTensor/tensor_meta shapes. That let symbolic dims leak into the generated ExecuTorch GraphModule and caused runtime failures when the lowered module was executed in Python. Build memory.alloc specs from concrete upper-bounded integer shapes instead. If an alloc shape is still not concretely bounded, raise a clear error. Add an EXIR regression test that exports a dynamic-shape model, runs ConstraintBasedSymShapeEvalPass + ToOutVarPass, and verifies that memory.alloc shapes are concrete integers. cc @digantdesai @freddan80 @per @zingo @mansnils @Sebastian-Larsson @robell @rascani --------- Signed-off-by: Oscar Andersson --- .../arm/test/models/test_torch_functions.py | 4 -- exir/passes/__init__.py | 28 +++++++---- exir/tests/test_passes.py | 49 +++++++++++++++++++ 3 files changed, 67 insertions(+), 14 deletions(-) diff --git a/backends/arm/test/models/test_torch_functions.py b/backends/arm/test/models/test_torch_functions.py index 0ca8d3ac091..c6a4c5580dc 100644 --- a/backends/arm/test/models/test_torch_functions.py +++ b/backends/arm/test/models/test_torch_functions.py @@ -97,8 +97,6 @@ def forward(self, *args): "test_data", test_parameters, xfails={ - "nonzero": "torch.fx.experimental.symbolic_shapes.GuardOnDataDependentSymNode: Could not guard on data-dependent expression Eq(u4, 0).

Three areas of change: GGUF loader (gguf_loader.py): - Add MLX backend support alongside CUDA - Keep embedding quantized for MLX (QuantizedEmbeddingHandler supports quantized gather natively, unlike CUDA's Int4Tensor) - Fix stale docstring references to Int4TilePackedTo4dTensor/tinygemm MLX backend (op_helpers.py, patterns.py): - Accept group_size=16 in parse_dequant_node for GGUF Q6_K tensors - For group_size < 32, emit DequantizeNode + TransposeNode + AddmmNode instead of QuantizedMatmulNode, since MLX Metal kernels are only instantiated for group_size >= 32. Weights stay packed as int8 in the .pte file and are dequantized on-device at runtime — same strategy CUDA/Inductor uses (separate Triton dequant + cuBLAS mm). Packer (pack_mlx.py): - Add 16 to supported group sizes so Q6_K IntxUnpackedToInt8Tensor passes through to export unchanged Tests (test_ops.py): - Add group_size=16 configs for int8, int4, and no-bias variants Test Plan: Export and run this model https://huggingface.co/unsloth/gemma-4-31B-it-GGUF/blob/main/gemma-4-31B-it-Q4_K_M.gguf On M1 32GB machine (exported on Linux A100) ``` (executorch_dev) mnachin@mnachin-mbp executorch % ./cmake-out/examples/models/gemma4_31b/gemma4_31b_runner \ --model_path /Users/mnachin/repos/models/gemma-4-31B-it-GGUF/model.pte \ --tokenizer_path /Users/mnachin/repos/models/gemma-4-31B-it-HQQ-INT4/tokenizer.json \ --prompt "Tell me a joke about RAM usage" \ --max_new_tokens 128 \ --temperature 0.8 I tokenizers:regex.cpp:27] Registering override fallback regex WARNING: All log messages before absl::InitializeLog() is called are written to STDERR E0000 00:00:1779926968.603672 54889180 re2.cc:237] Error parsing '((\|ool\|\>1\x00\x00\ �\|\|\<\|tool_response\>|\<\|think\|\>|\x0...': invalid UTF-8 I tokenizers:re2_regex.cpp:27] Re2 failed to compile regex: ((\|ool\|\>1\x00\x00\ �\|\|\<\|tool_response\>|\<\|think\|\>|\x00\x00\\\<|\|\|\<\|\"\|\>|all\|\>j\x00\x00\\|\|\<\|turn\>|\|\<\|image\>|\<\|$ I tokenizers:regex_lookahead.cpp:27] Creating PCRE2 regex I tokenizers:pcre2_regex.cpp:48] PCRE2 UTF-8 validation failed at offset 27: UTF-8 error: byte 2 top bits not 0x80.

The default hook returns true, preserving existing behavior for ArmPass subclasses. Introduce ArmOpTargetedPass for passes that only transform a known set of operator targets. It implements should_run_pass() by scanning the current graph and nested GraphModules for matching target operators. If no matching target operator is found, the pass returns an unmodified PassResult. For passes that already gate transformations with allowed_to_transform(), allow the target pre-scan to apply the same check before deciding whether the pass needs to run. This avoids running TFA passes when all matching target nodes are marked as disallowed. The should_run_pass() hook and ArmOpTargetedPass pre-scan avoid rebuilding graphs for decomposition and rewrite passes that cannot affect the current graph. The speedup is most visible on large models.

The exact string match in `propose_ghstack_orig_pr.py` no longer matched, causing every ghstack_land workflow run to fail since May 14. Use `startswith("Stack from [ghstack]")` instead to be resilient to URL changes.

Add TurboQuant TQ4 KV cache to the MLX backend, exposed on gemma4_31b via --turboquant. Compresses full-attention KV cache from bf16 to a 4-bit codebook + per-vector norms, letting Gemma 4 31B-IT scale to very long contexts. Sliding-window layers are unchanged. What's in the PR New cache subclass: - backends/mlx/llm/turboquant_cache.py: MLXTurboQuantKVCache, a drop-in subclass of TurboQuantKVCache. Three custom ops + Metal kernels: - mlx::tq4_compress (model_ops/tq4_compress.py): bucketize + cast(uint8) + nibble-pack in one kernel. - mlx::tq_norm (model_ops/tq_norm.py): L2 norm with simd_sum cross-lane reduction in fp32 registers; bf16 in / bf16 out. - mlx::tq_dequant (model_ops/tq_dequant.py): unpack + centroid gather + multiply-by-norm in one kernel. Per-op tests: - test_tq4_compress.py, test_tq_norm.py, test_tq_dequant.py Wiring: - examples/models/gemma4_31b/mlx_source_transformations.py: - examples/models/gemma4_31b/export.py: --turboquant CLI flag - examples/models/gemma4_31b/README.md: TurboQuant subsection. Perf on M4 Max 64GB Ram: ``` 2K prompt: bf16 cache: prefill 189.7 tok/s, decode 17.4 tok/s TurboQuant cache: prefill 187.7 tok/s, decode 16.9 tok/s 8K prompt: bf16 cache: prefill 170.0 tok/s, decode 17.1 tok/s TurboQuant cache: prefill 166.0 tok/s, decode 11.9 tok/s ``` For TQ, max context length is set to 64K.

The feature works by replacing all torch.nn.Linear submodules inside a graph by a custom implemented MXFP counterpart: `MXFPLinearOp`. A new user API called `to_mxfp` has been added to enable this feature (located in backends/arm/ao_ext/mxfp.py). The API is tagged as experimental for now. An eager CPU and fake implementation is added to the new custom op, but lowering it TOSA is handled in a later patch. To summarize, this patch enables the following flow: ```python m = MyModule() to_mxfp(m, MXFPOpConfig()) m.forward(x) ``` Signed-off-by: Martin Lindström Co-authored-by: Sebastian Larsson --- backends/arm/TARGETS | 27 ++- backends/arm/__init__.py | 6 + backends/arm/ao_ext/__init__.py | 12 + backends/arm/ao_ext/mxfp.py | 64 +++++ backends/arm/ao_ext/mxfp_tosa_lib.py | 11 + backends/arm/ao_ext/mxfp_transform.py | 24 ++ backends/arm/ao_ext/ops/__init__.py | 10 + backends/arm/ao_ext/ops/mxfp_linear_op.py | 179 ++++++++++++++ backends/arm/operators/op_view.py | 16 +- backends/arm/test/misc/test_mxfp_linear_ao.py | 46 ++++ backends/arm/test/ops/test_mxfp_linear.py | 226 ++++++++++++++++++ backends/arm/test/targets.bzl | 3 + .../arm/test/tester/analyze_output_utils.py | 32 ++- 13 files changed, 639 insertions(+), 17 deletions(-) create mode 100644 backends/arm/ao_ext/__init__.py create mode 100644 backends/arm/ao_ext/mxfp.py create mode 100644 backends/arm/ao_ext/mxfp_tosa_lib.py create mode 100644 backends/arm/ao_ext/mxfp_transform.py create mode 100644 backends/arm/ao_ext/ops/__init__.py create mode 100644 backends/arm/ao_ext/ops/mxfp_linear_op.py create mode 100644 backends/arm/test/misc/test_mxfp_linear_ao.py create mode 100644 backends/arm/test/ops/test_mxfp_linear.py diff --git a/backends/arm/TARGETS b/backends/arm/TARGETS index c3e2251bb11..a63237fe2c9 100644 --- a/backends/arm/TARGETS +++ b/backends/arm/TARGETS @@ -1,4 +1,4 @@ -# Copyright 2025 Arm Limited and/or its affiliates. +# Copyright 2025-2026 Arm Limited and/or its affiliates. # # This source code is licensed under the BSD-style license found in the # LICENSE file in the root directory of this source tree. @@ -15,6 +15,31 @@ runtime.python_library( "//executorch/exir/dialects:lib", ], ) +runtime.python_library( + name = "ao_ext", + srcs = glob([ + "ao_ext/*.py", + "ao_ext/ops/*.py", + ]), + deps = [ + "//caffe2:torch", + "//executorch/exir:_warnings", + "//pytorch/ao:torchao", + ], +) + +runtime.python_library( + name = "lib", + srcs = [ + "__init__.py", + ], + deps = [ + ":ao_ext", + ":ethosu", + ":vgf", + "//executorch/backends/arm/quantizer:lib", + ], +) runtime.python_library( name = "common", srcs = glob(["common/*.py"]), diff --git a/backends/arm/__init__.py b/backends/arm/__init__.py index fcbafa717ce..7c0b61457d0 100644 --- a/backends/arm/__init__.py +++ b/backends/arm/__init__.py @@ -14,6 +14,10 @@ import importlib from typing import Any +# Register Arm-specific torch.library ops and MXFP transforms at package +# import time. +import executorch.backends.arm.ao_ext # noqa: F401 + # Public for tooling (manifest generation and API validation).

Both fields are nullable in the schema, and the function is called from `Method::parse_external_constants` before `parseTensor` (which does null-check both) runs. Under the default `Verification::Minimal`, a corrupted `.pte`/`.ptd` with either field null causes a SIGSEGV instead of a clean error return. This PR adds the two missing null guards. Same pattern as #19267 and #17131, which hardened the same function. **Error code:** used `InvalidExternalData` to match the other checks inside `validateTensorLayout`. ### Test result ```bash ./test/run_oss_cpp_tests.sh lintrunner runtime/executor/tensor_parser_exec_aten.cpp \ runtime/executor/test/tensor_parser_test.cpp ``` Result: `0 tests failed out of 82`.

CI behavior changes: * macOS jobs in pull.yml / trunk.yml now skip on pushes that don't touch their paths and aren't in the sample * A new viable-strict-gate workflow runs on every push to main/release/* and fails when the commit isn't a sampled full-run. * update-viablestrict now requires the gate workflow → viable/strict advances ~every 4 commits instead of every commit. * Maintainers can force a full run on any main/release commit by running the new "Promote commit to viable/strict" workflow from the Actions tab * Sampling rule lives in one place: _ci-run-decision.yml; change the rate or rule there. --- .github/workflows/_ci-run-decision.yml | 91 +++++++++++ .github/workflows/_get-changed-files.yml | 76 +++++++-- .github/workflows/mlx.yml | 48 +++++- .../workflows/promote-to-viable-strict.yml | 145 ++++++++++++++++++ .github/workflows/pull.yml | 23 ++- .github/workflows/trunk.yml | 78 +++++++--- .github/workflows/update-viablestrict.yml | 4 +- .github/workflows/viable-strict-gate.yml | 51 ++++++ 8 files changed, 472 insertions(+), 44 deletions(-) create mode 100644 .github/workflows/_ci-run-decision.yml create mode 100644 .github/workflows/promote-to-viable-strict.yml create mode 100644 .github/workflows/viable-strict-gate.yml diff --git a/.github/workflows/_ci-run-decision.yml b/.github/workflows/_ci-run-decision.yml new file mode 100644 index 00000000000..99413f17d05 --- /dev/null +++ b/.github/workflows/_ci-run-decision.yml @@ -0,0 +1,91 @@ +name: CI Run Decision + +# Single source of truth for "should this commit force-run all CI jobs +# regardless of path filter?".

Since `coremldelegate` is included through `executorch_backends`, `executor_runner` could force-load both `portable_ops_lib` and `optimized_native_cpu_ops_lib`. Their generated static initializers register overlapping ATen kernels, causing `executor_runner` to abort before `main()` with a duplicate registration error. This removes the CoreML-side ops-lib link and removes the obsolete `EXECUTORCH_COREML_BUILD_EXECUTOR_RUNNER` preset option. The CoreML executor runner under `examples/apple/coreml/executor_runner` is not a CMake target, so this option was not actually building that runner. ### Compatibility The `coreml_executor_runner` built by `examples/apple/coreml/scripts/build_executor_runner.sh` is unaffected. That script builds the relevant CMake targets, then stages `libportable_ops_lib.a` and `libportable_kernels.a` into `examples/apple/coreml/executor_runner/libraries/`. The Xcode project links those archives directly, independent of `libcoremldelegate.a`'s internal link list, so the Xcode-built runner keeps working through its own link line. Other CMake consumers of `coremldelegate` already select an ops registration library independently before force-loading `coremldelegate`, so they are unaffected by removing the private portable-kernel link from the delegate. Non-Apple platforms do not build `coremldelegate` because `backends/apple/coreml/CMakeLists.txt` is gated by `if(APPLE)`. The iOS and iOS-simulator presets never set the removed option. ### Test plan ```bash cmake --preset macos cmake --build cmake-out --target executor_runner --config Debug -j ./cmake-out/Debug/executor_runner cmake --build cmake-out --target coremldelegate --config Debug -j ``` Verified the `executor_runner` link line no longer contains `libportable_ops_lib.a` or unprefixed `libportable_kernels.a`. `liboptimized_native_cpu_ops_lib.a` is still force-loaded. `liboptimized_portable_kernels.a` is still present, which is expected because it is one of `optimized_native_cpu_ops_lib`'s kernel libraries. Running without `--model_path` now reaches `main()`, resets the threadpool, and fails only on the expected missing `model.pte` path instead of aborting during static kernel registration.

This has the positive side effect that new files would be included in the linting and the exclude list can have a nice sorting and comments why things have ended up there. The end goal should of course be a empty exclude_patterns list.

The new fake ops preserve the reduced axis in the output shape and validate input rank, axis bounds, supported dtypes, profile and extension gating, and NaN propagation mode where required by the TOSA spec.

Two changes to `ConvertInt64OutputOpsToInt32Pass`. ## 1. argmin support `ConvertInt64OutputOpsToInt32Pass` inserts an `int64 → int32` cast after `aten.argmax` nodes so that the index output (TOSA has no int64) becomes int32 and downstream consumers can be delegated. `aten.argmin` returns int64 identically but was not handled — the committer explicitly deferred it as a future extension: > *"Future extensions may include operators that return int64 outputs by default (e.g., `argmin`) …"* ```mermaid flowchart LR subgraph before["Before"] direction LR A1["argmin\nint64"]:::cpu --> B1["mul\nint64"]:::blocked --> C1["add\nint64"]:::blocked end subgraph after["After"] direction LR A2["argmin\nint64"]:::cpu --> T["to_int32"]:::cpu T --> B2["mul\nint32"]:::delegated --> C2["add\nint32"]:::delegated end before ~~~ after classDef cpu fill:#f5c542,stroke:#b8962e,color:#000 classDef blocked fill:#e05c5c,stroke:#a33,color:#fff classDef delegated fill:#4caf7d,stroke:#2d7a54,color:#fff ``` **Changes:** Mirror the existing argmax registration to cover argmin. Rename the cast helper — it operates on the node's output dtype, not the op name, so the old name was misleading once argmin was added. --- ## 2. int32 overflow guard The pass previously had an open TODO: ```python # TODO: Add range check based on the input tensor shape before casting the output ``` `argmax`/`argmin` return an index in `[0, size)` where `size` is the number of elements searched. If `size > INT32_MAX`, casting to int32 silently truncates, producing a wrong index with no error. **Changes:** Add a compile-time shape check (`shape[dim]` or `numel()` for the no-dim form) and an `on_overflow` constructor param (`"raise"` / `"warn"` / `"skip"`, default `"raise"`). A compile-time error is preferable to a silent wrong result at runtime. --- ## Tests ```bash $ python -m pytest backends/arm/test/passes/test_convert_int64_output_ops_to_int32.py -v 9 passed # 5 existing + 2 parametrized [argmax]/[argmin] delegation + 4 overflow (raise/warn/skip/invalid) $ lintrunner backends/arm/_passes/convert_int64_output_ops_to_int32.py \ backends/arm/test/passes/test_convert_int64_output_ops_to_int32.py ok No lint issues. ``` The argmax and argmin delegation cases are unified into a single `@pytest.mark.parametrize` test.

The example implement an executorch runner for the ESP32 platform and a project that executes a simple network. The example does not use ops optimized for ESP32 platform but demonstrate feasibility. ### Test plan This example was tested on a ESP32-S3 development platform. The project compiles and when loaded on the platform show the expected log trace. cc @psiddh @AdrianLundell @digantdesai --------- Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> Co-authored-by: RJ Ascani --- CMakePresets.json | 8 + examples/espressif/README.md | 272 ++++ examples/espressif/build.sh | 110 ++ .../espressif/executor_runner/CMakeLists.txt | 315 +++++ .../executor_runner/esp_executor_runner.cpp | 1240 +++++++++++++++++ .../executor_runner/esp_executor_runner.h | 98 ++ .../executor_runner/esp_memory_allocator.cpp | 36 + .../executor_runner/esp_memory_allocator.h | 35 + .../espressif/executor_runner/esp_pal.cpp | 95 ++ .../executor_runner/esp_perf_monitor.cpp | 100 ++ .../executor_runner/esp_perf_monitor.h | 18 + .../executor_runner/pte_to_header.py | 98 ++ examples/espressif/project/CMakeLists.txt | 27 + .../espressif/project/main/CMakeLists.txt | 12 + examples/espressif/project/main/main.cpp | 36 + examples/espressif/project/partitions.csv | 5 + examples/espressif/project/sdkconfig.defaults | 50 + .../project/sdkconfig.defaults.esp32s3 | 42 + extension/threadpool/threadpool.cpp | 2 +- tools/cmake/preset/esp_baremetal.cmake | 20 + 20 files changed, 2618 insertions(+), 1 deletion(-) create mode 100644 examples/espressif/README.md create mode 100755 examples/espressif/build.sh create mode 100644 examples/espressif/executor_runner/CMakeLists.txt create mode 100644 examples/espressif/executor_runner/esp_executor_runner.cpp create mode 100644 examples/espressif/executor_runner/esp_executor_runner.h create mode 100644 examples/espressif/executor_runner/esp_memory_allocator.cpp create mode 100644 examples/espressif/executor_runner/esp_memory_allocator.h create mode 100644 examples/espressif/executor_runner/esp_pal.cpp create mode 100644 examples/espressif/executor_runner/esp_perf_monitor.cpp create mode 100644 examples/espressif/executor_runner/esp_perf_monitor.h create mode 100644 examples/espressif/executor_runner/pte_to_header.py create mode 100644 examples/espressif/project/CMakeLists.txt create mode 100644 examples/espressif/project/main/CMakeLists.txt create mode 100644 examples/espressif/project/main/main.cpp create mode 100644 examples/espressif/project/partitions.csv create mode 100644 examples/espressif/project/sdkconfig.defaults create mode 100644 examples/espressif/project/sdkconfig.defaults.esp32s3 create mode 100644 tools/cmake/preset/esp_baremetal.cmake diff --git a/CMakePresets.json b/CMakePresets.json index 91848565067..6ddea5fd69c 100644 --- a/CMakePresets.json +++ b/CMakePresets.json @@ -313,6 +313,14 @@ "CMAKE_TOOLCHAIN_FILE": "${sourceDir}/examples/arm/ethos-u-setup/aarch64-linux-musl-toolchain.cmake" } }, + { + "name": "esp-baremetal", + "displayName": "Build ExecuTorch for ESP baremetal", + "inherits": ["common"], + "cacheVariables": { + "EXECUTORCH_BUILD_PRESET_FILE": "${sourceDir}/tools/cmake/preset/esp_baremetal.cmake" + } + }, { "name": "riscv64-linux", "displayName": "Build ExecuTorch for riscv64 Linux (cross-compile)", diff --git a/examples/espressif/README.md b/examples/espressif/README.md new file mode 100644 index 00000000000..025bdf94094 --- /dev/null +++ b/examples/espressif/README.md @@ -0,0 +1,272 @@ +# ExecuTorch Executor Runner for Espressif ESP32/ESP32-S3 + +> **Warning:** This example is not tested in CI.

If the Python installer failed but git config succeeded, the final command overwrote the nonzero status and CI continued into pytest with the stale editable install left in env/. Enable shell errexit so install_executorch.sh stops as soon as the Python installer fails. Successful installs still continue to configure git hooks, and hook setup failures still surface as wrapper failures.

These are supported via a new segment type and intermediate resources and required a fairly large refactoring of the VGF runtime to accomodate per-segment state. The changes cover: Various bugfixes/improvements found when adding segment support Add VGF custom shader runtime tests Add single-segment compute support in VGF runtime Add per-segment VGF runtime state for multi-segment support Support intermediate VGF resources between segments Add image and sampler support to VGF runtime for shaders Add shared alias backing for VGF resources (VGF schema changes) Add image/tensor alias layouts for VGF resources Broaden VGF aliasing barriers for graph and compute Specifically for users: Add custom operator VGF tutorial Define incoming tensor ABI/layout rules for shaders Fix VGF grid_sampler NHWC lowering and tests Defn. channel order for custom ops and passes due to https://github.com/pytorch/executorch/commit/1bb039ff3335b834aea67b4feb5eaf256a2a641e: Signed-off-by: Rob Elliott [Robert.Elliott@arm.com](mailto:Robert.Elliott@arm.com) Change-Id: Ie13e5561197ac141eee9d596a74993107933f921 TESTING: For testing, there are new tests which are currently disabled until dependencies are packaged into new releases. For now the newer functionality for shaders and samplers and resource aliases are xfailed on the current release hash of model-converter. When the hash is bumped they will run and should pass. For provenance the additional tests with a newer model-converter and vgf-lib produce: pytest backends/arm/test/passes/test_custom_op_rewrite.py backends/arm/test/misc/test_custom_shader_payloads.py

Wired into the test-arm-cortex-m-size-test job only — the existing ls -la threshold check is untouched. Other size jobs will be wired up in follow-up PRs in this stack; later PRs add the sticky PR comment and replace the coarse byte threshold with per-bucket gating. ### Test Plan CI artifact creation Authored with Claude. --- .github/scripts/bloaty_diff.py | 270 +++++++++++++++++++++++++++++++++ .github/workflows/pull.yml | 28 ++++ test/bloaty/executorch.bloaty | 72 +++++++++ 3 files changed, 370 insertions(+) create mode 100755 .github/scripts/bloaty_diff.py create mode 100644 test/bloaty/executorch.bloaty diff --git a/.github/scripts/bloaty_diff.py b/.github/scripts/bloaty_diff.py new file mode 100755 index 00000000000..763c6240923 --- /dev/null +++ b/.github/scripts/bloaty_diff.py @@ -0,0 +1,270 @@ +#!/usr/bin/env python3 +# Copyright (c) Meta Platforms, Inc. and affiliates. +# All rights reserved. +# +# This source code is licensed under the BSD-style license found in the +# LICENSE file in the root directory of this source tree. + +"""Bloaty binary-size reports for CI.""" + +import argparse +import csv +import io +import json +import os +import shlex +import subprocess +import sys +from dataclasses import asdict, dataclass, field +from pathlib import Path +from typing import Dict, List, Optional + +REPO_ROOT = Path(__file__).resolve().parent.parent.parent +BLOATY_CONFIG = REPO_ROOT / "test" / "bloaty" / "executorch.bloaty" +BLOATY_CMD = shlex.split(os.environ.get("BLOATY", "bloaty")) + +# Buckets considered "ExecuTorch source code" for the summary table.

The shader mirrors the Vulkan implementation (`backends/vulkan/runtime/graph/ops/impl/RmsNorm.cpp`, `backends/vulkan/runtime/graph/ops/glsl/rms_norm_buffer.glsl`); indexing assumes contiguous fp32 inputs. The handler fails loud (throws, mirroring Vulkan's `VK_CHECK_COND`) on invalid shape/dtype/dispatch-limit conditions, and defaults `eps` to the float32 machine epsilon. The weight constant is uploaded via the named-data path added in the parent diff. ghstack-source-id: 389206169 @exported-using-ghexport Differential Revision: [D106887028](https://our.internmc.facebook.com/intern/diff/D106887028/) --- backends/webgpu/CMakeLists.txt | 41 +++- .../webgpu/runtime/ops/rms_norm/RmsNorm.cpp | 195 ++++++++++++++++++ .../webgpu/runtime/ops/rms_norm/rms_norm.wgsl | 75 +++++++ .../runtime/ops/rms_norm/rms_norm_wgsl.h | 98 +++++++++ backends/webgpu/test/native/test_rms_norm.cpp | 173 ++++++++++++++++ backends/webgpu/test/ops/rms_norm/__init__.py | 0 .../webgpu/test/ops/rms_norm/test_rms_norm.py | 191 +++++++++++++++++ backends/webgpu/test/test_build_webgpu.sh | 28 ++- backends/webgpu/test/test_webgpu_native.cpp | 2 + 9 files changed, 796 insertions(+), 7 deletions(-) create mode 100644 backends/webgpu/runtime/ops/rms_norm/RmsNorm.cpp create mode 100644 backends/webgpu/runtime/ops/rms_norm/rms_norm.wgsl create mode 100644 backends/webgpu/runtime/ops/rms_norm/rms_norm_wgsl.h create mode 100644 backends/webgpu/test/native/test_rms_norm.cpp create mode 100644 backends/webgpu/test/ops/rms_norm/__init__.py create mode 100644 backends/webgpu/test/ops/rms_norm/test_rms_norm.py diff --git a/backends/webgpu/CMakeLists.txt b/backends/webgpu/CMakeLists.txt index ab2da24a569..972518f1399 100644 --- a/backends/webgpu/CMakeLists.txt +++ b/backends/webgpu/CMakeLists.txt @@ -26,9 +26,13 @@ if(NOT TARGET vulkan_schema) endif() set(WEBGPU_SRCS - runtime/WebGPUBackend.cpp runtime/WebGPUGraph.cpp - runtime/WebGPUDelegateHeader.cpp runtime/WebGPUDevice.cpp - runtime/ops/OperatorRegistry.cpp runtime/ops/add/BinaryOp.cpp + runtime/WebGPUBackend.cpp + runtime/WebGPUGraph.cpp + runtime/WebGPUDelegateHeader.cpp + runtime/WebGPUDevice.cpp + runtime/ops/OperatorRegistry.cpp + runtime/ops/add/BinaryOp.cpp + runtime/ops/rms_norm/RmsNorm.cpp ) add_library(webgpu_backend ${WEBGPU_SRCS}) @@ -116,4 +120,35 @@ if(EXECUTORCH_BUILD_WEBGPU_TEST) target_compile_options(webgpu_native_test PRIVATE -fexceptions) set_property(TARGET webgpu_native_test PROPERTY CXX_STANDARD 17) + + add_executable(webgpu_rms_norm_test test/native/test_rms_norm.cpp) + + target_include_directories( + webgpu_rms_norm_test PRIVATE $ + "${WGPU_NATIVE_DIR}/include" + ) + + target_link_libraries( + webgpu_rms_norm_test + PRIVATE webgpu_backend + wgpu_native + executorch_core + extension_module_static + extension_data_loader + extension_tensor + portable_kernels + portable_ops_lib + ) + + if(APPLE) + target_link_libraries( + webgpu_rms_norm_test PRIVATE "-framework Metal" "-framework QuartzCore" + "-framework CoreGraphics" + ) + else() + target_link_libraries(webgpu_rms_norm_test PRIVATE dl m pthread) + endif() + + target_compile_options(webgpu_rms_norm_test PRIVATE -fexceptions) + set_property(TARGET webgpu_rms_norm_test PROPERTY CXX_STANDARD 17) endif() diff --git a/backends/webgpu/runtime/ops/rms_norm/RmsNorm.cpp b/backends/webgpu/runtime/ops/rms_norm/RmsNorm.cpp new file mode 100644 index 00000000000..3820c9fa2bd --- /dev/null +++ b/backends/webgpu/runtime/ops/rms_norm/RmsNorm.cpp @@ -0,0 +1,195 @@ +/* + * Copyright (c) Meta Platforms, Inc. and affiliates. + * All rights reserved. + * + * This source code is licensed under the BSD-style license found in the + * LICENSE file in the root directory of this source tree. + */ + +#include +#include +#include + +#include + +#include +#include +#include +#include + +namespace executorch::backends::webgpu { + +namespace { + +// Uniform layout matching the WGSL Params struct (16-byte aligned). +struct RmsNormParams { + uint32_t num_rows;

Two fixes were needed for SwiftShader's downlevel limits: request the adapter's full `requiredLimits` at device creation (software adapters default storage-buffer limits to 0), and make the `add` op's workgroup size dynamic instead of a hardcoded constant. The WGSL now declares a pipeline-overridable `override wg_size: u32 = 256` and the host clamps it to the device's `maxComputeInvocationsPerWorkgroup` (256 on real GPUs and lavapipe, 128 on SwiftShader), so SwiftShader's 128-invocation cap no longer forces a smaller workgroup size on real hardware. This mirrors the dynamic-workgroup-sizing approach in D107259348 and opens the door to selecting device/algorithm-optimal sizes later. The `add` op also validates its 1D dispatch count before allocating any GPU objects, against the device's queried `maxComputeWorkgroupsPerDimension` (falling back to the WebGPU spec-default floor of 65535 only when the limit query fails). Per Stephen's review, the workgroup-size clamp and the dispatch-count computation are factored into reusable `inline` helpers in `runtime/WebGPUUtils.h` (`clamp_workgroup_size` and `compute_1d_workgroup_count`, mirroring the Vulkan delegate's `utils::div_up`) so the other ops can share them rather than re-inlining the logic. The editable CMake build additionally marks the `vulkan_schema` subdirectory `EXCLUDE_FROM_ALL` so the WebGPU `ALL` build does not pull in targets that need glslc. ghstack-source-id: 389636486 @exported-using-ghexport Differential Revision: [D107288999](https://our.internmc.facebook.com/intern/diff/D107288999/) --- .ci/scripts/setup-webgpu-linux-deps.sh | 30 +++++++++ .ci/scripts/test_backend.sh | 8 +++ .github/workflows/test-backend-webgpu.yml | 27 ++++++++ CMakeLists.txt | 4 ++ backends/test/suite/flow.py | 7 ++ backends/test/suite/flows/webgpu.py | 20 ++++++ backends/webgpu/CMakeLists.txt | 2 +- backends/webgpu/__init__.py | 5 ++ backends/webgpu/runtime/WebGPUDevice.cpp | 6 ++ backends/webgpu/runtime/WebGPUUtils.h | 51 +++++++++++++++ backends/webgpu/runtime/ops/add/BinaryOp.cpp | 18 +++-- .../webgpu/runtime/ops/add/binary_add.wgsl | 4 +- .../webgpu/runtime/ops/add/binary_add_wgsl.h | 4 +- backends/webgpu/test/TARGETS | 27 ++++++++ backends/webgpu/test/ops/add/test_add.py | 2 +- backends/webgpu/test/tester.py | 65 +++++++++++++++++++ 16 files changed, 272 insertions(+), 8 deletions(-) create mode 100644 .ci/scripts/setup-webgpu-linux-deps.sh create mode 100644 .github/workflows/test-backend-webgpu.yml create mode 100644 backends/test/suite/flows/webgpu.py create mode 100644 backends/webgpu/__init__.py create mode 100644 backends/webgpu/runtime/WebGPUUtils.h create mode 100644 backends/webgpu/test/TARGETS create mode 100644 backends/webgpu/test/tester.py diff --git a/.ci/scripts/setup-webgpu-linux-deps.sh b/.ci/scripts/setup-webgpu-linux-deps.sh new file mode 100644 index 00000000000..8ece5899489 --- /dev/null +++ b/.ci/scripts/setup-webgpu-linux-deps.sh @@ -0,0 +1,30 @@ +#!/bin/bash +# Copyright (c) Meta Platforms, Inc. and affiliates. +# All rights reserved. +# +# This source code is licensed under the BSD-style license found in the +# LICENSE file in the root directory of this source tree. + +set -ex + +# SwiftShader: software Vulkan adapter for GPU-less CI (LunarG SDK not needed). +install_swiftshader() { + _https_amazon_aws=https://ossci-android.s3.amazonaws.com + _swiftshader_archive=swiftshader-abe07b943-prebuilt.tar.gz + _swiftshader_dir=/tmp/swiftshader + mkdir -p $_swiftshader_dir + + _tmp_archive="/tmp/${_swiftshader_archive}" + + curl --silent --show-error --location --fail --retry 3 --retry-all-errors \ + --output "${_tmp_archive}" "$_https_amazon_aws/${_swiftshader_archive}" + + tar -C "${_swiftshader_dir}" -xzf "${_tmp_archive}" + + export VK_ICD_FILENAMES="${_swiftshader_dir}/swiftshader/build/Linux/vk_swiftshader_icd.json" + export LD_LIBRARY_PATH="${_swiftshader_dir}/swiftshader/build/Linux/:${LD_LIBRARY_PATH}" + export ETVK_USING_SWIFTSHADER=1 +} + +install_swiftshader +bash backends/webgpu/scripts/setup-wgpu-native.sh diff --git a/.ci/scripts/test_backend.sh b/.ci/scripts/test_backend.sh index a7f89f820b2..fe9b564a18f 100755 --- a/.ci/scripts/test_backend.sh +++ b/.ci/scripts/test_backend.sh @@ -57,6 +57,14 @@ if [[ "$FLOW" == *vulkan* ]];

Default to all three: `QcomCosineSimilarityComparator(threshold=0.9)`, `QcomMSEComparator(threshold=0.1)`, and `QcomSQNRComparator(threshold=10.0)` (SQNR is in dB, larger is better) unless the user specifies otherwise. + - Calls `qnn_intermediate_debugger.generate_results(title=..., path=args.artifact, output_format=OutputFormat.SVG_GRAPH | CSV_FILE, comparator=...)` for each comparator/format combination wanted. + +6. **Wire the callback into `adb.pull_debug_output`**: + ```python + adb.pull_debug_output(args.artifact, args.artifact, callback=validate_intermediate_tensor) + ``` + +7. **Preserve the user's downstream eval logic** (top-k accuracy, IPC client back to a remote, etc.) but it's now running on a single sample — note that in a comment so the user isn't surprised by degenerate metrics. + +8. **Assert `dump_intermediate_outputs` at startup** — match the demo's `__main__` block: + ```python + assert args.dump_intermediate_outputs, ( + "In order to use intermediate tensor debugger, please provide " + "the flag --dump_intermediate_outputs when executing." + ) + ``` + +### 5. Tell the user how to run it + +Construct the run command from the original command they gave you in step 1. **Do not print a generic template** — return the exact command they will copy-paste. Transformation rules: + +1. **Swap the script target** — replace the path / module of their original script with the path / module of the generated debug script. + - If they ran `python -m examples.qualcomm.scripts.foo ...`, change the module to wherever you saved the debug script (e.g. `python -m examples.qualcomm.util_scripts.foo_debug ...`). + - If they ran `python examples/qualcomm/scripts/foo.py ...`, change the path the same way. +2. **Keep every flag the user had** — `-H`, `-s`, `-m`, `-b`, `-d`, `-a`, any model-specific flags, etc. The debug script reuses `setup_common_args_and_variables`, so they all still apply. +3. **Add `--dump_intermediate_outputs` if it is not already present.** If they already had it, leave it once — don't duplicate. +4. **Auto-detect required env vars from the current shell** — do not ask the user. + - Check `QNN_SDK_ROOT`, `LD_LIBRARY_PATH`, and `PYTHONPATH` via the Bash tool (`echo $QNN_SDK_ROOT`, etc.). + - If a variable is already set in the shell, the user's existing process inherits it — do **not** prepend it to the command (it would be redundant and noisy). + - If a variable is **unset** but is required for the QNN flow (typically `QNN_SDK_ROOT`), prepend it inline only if you can determine a sensible value (e.g. from a previous build invocation in this conversation). Otherwise call it out as a prerequisite the user needs to export themselves rather than hardcoding a guess. +5. **Format on multiple lines with `\` continuations** for readability when the command is long. + +Present the result as a fenced bash block, prefixed by a one-line note of what changed vs. their original. Example output: + +> Here's the command — same as your original, with the script swapped to the new debug file and `--dump_intermediate_outputs` added: +> +> ```bash +> python -m examples.qualcomm.util_scripts.my_model_debug \ +> -H $HOST -s $DEVICE_SERIAL -m $SOC_MODEL -b build-android \ +> -d /path/to/dataset -a ./my_model_debug \ +> --dump_intermediate_outputs +> ``` + +If the user did not give you a runnable original command in step 1 (e.g. they pasted only the script path), do **not** fabricate values for `-H` / `-s` / `-m` / `-b` / `-a` / `-d`. Stop and ask before printing — wrong device or SoC values waste a full export + on-device run. + +After the command runs, the artifact dir will contain SVG / CSV reports — green nodes pass, red nodes fail the comparator threshold. That's the first place to look for the layer that introduces the gap. + +--- + +## Comparators — defaults and customization + +Out-of-the-box (from `qcom_numerical_comparator_sample.py`): +- `QcomCosineSimilarityComparator(threshold=0.9)` — flag if cosine drops below 0.9 +- `QcomMSEComparator(threshold=0.1)` — flag if MSE exceeds 0.1 +- `QcomSQNRComparator(threshold=10.0)` — flag if SQNR (dB) drops below 10. Backed by `torchao.quantization.utils.compute_error`. Larger is better; 10 dB is a permissive baseline for INT8 quantized graphs — tighten for FP16. + +If the user wants something else (e.g. max abs diff, custom logit-space metric), point them at `QcomNumericalComparatorBase` and stub out a derived class. The base handles QNN dequantization + layout transform via `preprocessing` — they only implement `metric_name()`, `is_valid_score()`, and `element_compare()`. Do **not** override `preprocessing`; the base intentionally locks it down. + +--- + +## Handling model outputs (highest-risk part of generation) + +The nn.Module-vs-edge sanity check looks innocent in the demo (Inception V3 returns a single tensor) but breaks silently the moment a real model returns anything else. Before writing this block, **inspect what the user's model and edge graph actually return** — don't assume it's a single tensor. The same care applies to both sides; the eager `nn.Module` and `edge_ep.module()` may return different shapes/structures even from the same source model. + +### Common output shapes and how to handle them + +| Eager model returns | What you must do | +|---|---| +| Single `Tensor` | `out.flatten()` directly. | +| `tuple` / `list` of tensors (e.g. classifier + aux head, encoder hidden states) | Compare **every** element pairwise. Don't pick `[0]` and call it done — the user is debugging accuracy, hidden divergence in the dropped outputs is exactly what they're trying to find. | +| Custom dataclass / `ModelOutput` (HuggingFace style — `BaseModelOutput`, `CausalLMOutputWithPast`, etc.) | Extract the tensor field(s) explicitly (`out.logits`, `out.last_hidden_state`, etc.). Field name varies by model — read the user's model definition or the eager output's `.__dataclass_fields__` to confirm. | +| `dict` of tensors | Iterate over keys; sanity-check both sides have the same key set first. | +| Tensors with different dtypes between eager and edge | Cast to a common dtype (typically `float32`) before similarity. | + +### Required generation behavior + +1. **Compute eager and edge outputs first**, then branch on their actual structure. Don't hardcode `result.flatten()` — write a small adapter that inspects the type and pulls tensors out. +2. **Compare every output**, not just `[0]`. For a multi-output model, emit one similarity score per output and label them (e.g. `output[0]: cos=0.998`, `logits: cos=0.92`). +3. **Match what the model's `forward` actually accepts.** `qnn_intermediate_debugger.sample_input` is what the debugger was constructed with — verify that calling `source_model(*sample_input)` and `edge_ep.module()(*sample_input)` both work with the user's signature. Some users pass kwargs, some pass a single tensor without unpacking, some pass a tuple. Mirror exactly what their existing script does. +4. **If the eager and edge outputs structurally differ** (e.g. eager returns a dataclass but edge returns a tuple after `torch.export`), normalize both into the same shape (typically a flat list of tensors in declared order) before comparing. +5. **If anything is ambiguous after reading the model, stop and ask the user.** Wrong handling here silently invalidates the entire downstream comparison and is the most likely way for this generated script to mislead the user. + +### Sketch (for a single-tensor model) + +```python +edge_result = qnn_intermediate_debugger.edge_ep.module()(*qnn_intermediate_debugger.sample_input) +with torch.no_grad(): + source_result = source_model(*qnn_intermediate_debugger.sample_input) +score = torch.nn.functional.cosine_similarity( + edge_result.flatten().to(torch.float32), + source_result.flatten().to(torch.float32), + dim=0, +).item() +print(f"Cosine similarity (nn.Module vs edge CPU): {score:.6f}") +``` + +### Sketch (for a multi-output / dataclass model — adapt to actual structure) + +```python +def _to_tensor_list(out): + if isinstance(out, torch.Tensor): + return [out] + if isinstance(out, (list, tuple)): + return [t for t in out if isinstance(t, torch.Tensor)] + # Dataclass / ModelOutput — pick the fields the user actually cares about + return [getattr(out, name) for name in ("logits", "last_hidden_state") if hasattr(out, name)] + +edge_tensors = _to_tensor_list(qnn_intermediate_debugger.edge_ep.module()(*qnn_intermediate_debugger.sample_input)) +with torch.no_grad(): + source_tensors = _to_tensor_list(source_model(*qnn_intermediate_debugger.sample_input)) + +assert len(edge_tensors) == len(source_tensors), ( + f"Output count mismatch: edge={len(edge_tensors)} vs eager={len(source_tensors)}" +) +for i, (e, s) in enumerate(zip(edge_tensors, source_tensors)): + score = torch.nn.functional.cosine_similarity( + e.flatten().to(torch.float32), s.flatten().to(torch.float32), dim=0 + ).item() + print(f"Cosine similarity[{i}] (nn.Module vs edge CPU): {score:.6f}") +``` + +The exact field names in `_to_tensor_list` are placeholders — replace with what the user's model actually returns.

Always reduce dataset to a single sample. +2. **No partial delegation.** If their model has CPU fallbacks, the comparator graph may be incomplete or wrong. Verify full delegation first (see `model_enablement.md` step 3). +3. **No LLM models.** +4. **No multi-method graphs.** +5. **Custom runners must implement etdump.** If the user wrote their own runner instead of using `qnn_executor_runner`, point them at the [etdump tutorial](https://pytorch.org/executorch/stable/etdump.html). Without etdump, no `etdump.etdp` is produced and the inspector has nothing to compare. +6. **`--dump_intermediate_outputs` is required.** Otherwise QNN doesn't dump per-layer tensors and the entire pipeline collapses. + +If any of 2–4 apply, tell the user this skill's output won't help them and stop — don't generate a script that will silently produce garbage. + +--- + +## Common pitfalls when generating + +- **Forgetting to slice the dataset to one sample** — script will run multiple times, debug output is undefined. +- **Using `inputs[0]` as `sample_input` when `inputs` is a list of tuples** — `QNNIntermediateDebugger(sample_input=...)` expects the same shape that the model's `forward` accepts. Match what the user's existing script passes to `model(*inputs)`. +- **Reusing the user's `dataset=inputs` after slicing** — `build_executorch_binary` wants the *original* (calibration) dataset for quantization; only the post-build inference path is sliced. Slice after `build_executorch_binary`, before `adb.push`. +- **Overriding `preprocessing` on a custom comparator** — base class raises `TypeError` in `__init_subclass__`. Don't try. +- **Skipping the nn.Module-vs-edge cosine check** — per-layer comparisons compare QNN against the edge CPU graph, not against eager. If the edge graph already differs from eager (quant calibration, pass transform), every "failure" downstream may be a red herring.

It checks that the TOSA serializer and ML SDK model converter are available and that the converter can be launched. Use `--runtime` when debugging Python runtime availability. It checks whether the ExecuTorch runtime backend registry reports VgfBackend as available. Use `--host-emulator` before host-based emulator runs. It checks runtime availability plus Vulkan SDK and ML emulation layer environment variables. Use `--source-build --build-dir ` when debugging a source build. It checks for VGF runtime build prerequisites such as `libvgf` and CMake options including `EXECUTORCH_BUILD_VGF` and `EXECUTORCH_BUILD_VULKAN`.

The no-quant mixed INT+FP profile does not run that pipeline, so the original ops can reach the partitioner and be rejected because they are absent from TOSA_PRO_INT_SupportList. However, these ops can still be supported by decomposition passes in the backend pipeline. Add a mixed INT support list that extends TOSA_PRO_INT_SupportList with backend-decomposable integer ops for mixed-profile partitioning. Include slice_scatter in that extension and remove the corresponding VGF no-quant xfails Change-Id: I0ccc5484dc8c8311cefb069df9e2a4878bd98c9a cc @digantdesai @freddan80 @per @zingo @oscarandersson8218 @mansnils @Sebastian-Larsson @robell @rascani Signed-off-by: Yufeng Shi --- .../tosa_profile_supported_op_lists.py | 17 +++++++++++++++++ .../tosa_supported_operators.py | 3 ++- backends/arm/test/ops/test_slice_scatter.py | 6 ------ 3 files changed, 19 insertions(+), 7 deletions(-) diff --git a/backends/arm/operator_support/tosa_profile_supported_op_lists.py b/backends/arm/operator_support/tosa_profile_supported_op_lists.py index c96f966a2e2..fab4e6c60c1 100644 --- a/backends/arm/operator_support/tosa_profile_supported_op_lists.py +++ b/backends/arm/operator_support/tosa_profile_supported_op_lists.py @@ -131,6 +131,22 @@ } +# Extra integer ops for the mixed INT+FP support list.

Each job now uploads a bloaty- artifact with metadata.json + full.txt + head_only.txt and emits a per-bucket markdown table to its GitHub Actions step summary. No gate change. The existing `ls -la` threshold checks are untouched and will be replaced by per-bucket gating in a later PR in this stack. ### Test plan Validate remaining size jobs now have step summaries and bloaty artifacts.

From 5baf3f9a136c0eaf34bd62b09277b4e61e81b21d Mon Sep 17 00:00:00 2001 From: zhaoxul-qti Date: Thu, 4 Jun 2026 23:28:28 +0800 Subject: [PATCH 170/317] Qualcomm AI Engine Direct - Support MSVC-compatible code (#19686) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary ### 1. Remove the **designated initializers** for C++ Why it compiles on Linux but not on Windows MSVC? - Designated initializers for C++ aggregates were standardized in C++20. GCC and Clang have supported them as a C++11/14/17 extension — they silently accept the syntax even when compiling in `-std=c++17` mode. MSVC is strictly conformant: it only accepts designated initializers when `/std:c++20` (or `/std:c++latest`) is active. ### 2. Remove the **GNU statement expressions** Why it compiles on Linux but not on Windows MSVC? - The GNU statement expression is a GNU C / GNU C++ language extension that lets you treat a block of statements as if it were a single expression that produces a value. It is not part of standard C or C++, but it is widely supported by GCC and Clang. MSVC does not support it. ### 3. Replace `constexpr` inside the lambda `[&]` - `ET_INTERNAL_SWITCH` wraps the `NAME` in `[&] { ... }()`. The `[&]` capture means the lambda captures all local variables by reference, including `NAME`. - However, inside the lambda `[&]`, `NAME` is accessed via the closure's implicit `this` pointer — it is `(*this).name` in the closure's internal representation to capture variables by reference. Dereferencing `this` is not a constant expression because `this` is a runtime pointer to the closure object, which is not a constant expression and only exists at runtime. Why it compiles on Linux but not on Windows MSVC? - GCC and Clang are more permissive here. They apply a special rule: if the captured variable is itself `constexpr` and its value is a compile-time constant, they allow it to be used as a constant expression inside the lambda, effectively treating the capture as a constant propagation rather than a runtime dereference. This is a quality-of-implementation extension beyond what the standard strictly requires. ### 4. Replace the `__attribute__((visibility("default")))` with corresponding MSVC-compatible syntax - Use Microsoft-specific C/C++ extensions `__declspec(dllexport)` and `__declspec(dllimport)` to control symbol visibility when working with Windows DLLs. --- .../aot/wrappers/QuantizeParamsWrapper.h | 6 +- .../qualcomm/aot/wrappers/TensorWrapper.h | 9 ++- backends/qualcomm/runtime/QnnExecuTorch.h | 20 ++++-- backends/qualcomm/runtime/QnnManager.cpp | 1 + examples/models/llama/main.cpp | 4 +- .../runner/attention_sink_rope_runner.cpp | 6 +- .../llama/runner/lhd_token_generator.cpp | 5 +- .../multimodal_lhd_token_generator.cpp | 5 +- .../multimodal_runner/multimodal_runner.cpp | 25 ++++--- .../oss_scripts/llama/runner/runner.cpp | 28 ++++---- .../llama/runner/token_generator.cpp | 5 +- .../qualcomm/oss_scripts/llama/runner/utils.h | 1 + .../qualcomm/oss_scripts/t5/runner/runner.cpp | 5 +- .../oss_scripts/whisper/runner/runner.cpp | 5 +- .../qaihub_scripts/llama/runner/io_memory.cpp | 3 +- extension/llm/runner/util.h | 25 +++---- .../core/exec_aten/util/scalar_type_util.h | 2 +- runtime/core/result.h | 67 +++++++++---------- 18 files changed, 127 insertions(+), 95 deletions(-) diff --git a/backends/qualcomm/aot/wrappers/QuantizeParamsWrapper.h b/backends/qualcomm/aot/wrappers/QuantizeParamsWrapper.h index 86d137723aa..f22f3dbf618 100644 --- a/backends/qualcomm/aot/wrappers/QuantizeParamsWrapper.h +++ b/backends/qualcomm/aot/wrappers/QuantizeParamsWrapper.h @@ -70,9 +70,9 @@ class UndefinedQuantizeParamsWrapper final : public QuantizeParamsWrapper { } Qnn_QuantizeParams_t CreateQuantizeParams() override { - Qnn_QuantizeParams_t rval = { - .encodingDefinition = GetEncodingDefinition(), - .quantizationEncoding = GetQuantizationEncoding()}; + Qnn_QuantizeParams_t rval; + rval.encodingDefinition = GetEncodingDefinition(); + rval.quantizationEncoding = GetQuantizationEncoding(); return rval; } }; diff --git a/backends/qualcomm/aot/wrappers/TensorWrapper.h b/backends/qualcomm/aot/wrappers/TensorWrapper.h index d8661acc492..98f59532afb 100644 --- a/backends/qualcomm/aot/wrappers/TensorWrapper.h +++ b/backends/qualcomm/aot/wrappers/TensorWrapper.h @@ -130,9 +130,12 @@ class TensorWrapper { std::unique_ptr owned_data_; bool created_{false}; - Qnn_Tensor_t tensor_ = { - .version = QNN_TENSOR_VERSION_2, - .v2 = QNN_TENSOR_V2_INIT}; + Qnn_Tensor_t tensor_ = []() noexcept { + Qnn_Tensor_t t{}; + t.version = QNN_TENSOR_VERSION_2; + t.v2 = QNN_TENSOR_V2_INIT; + return t; + }(); }; // base function for Create TensorWrapper std::shared_ptr CreateTensorWrapper( diff --git a/backends/qualcomm/runtime/QnnExecuTorch.h b/backends/qualcomm/runtime/QnnExecuTorch.h index 9699e5b4735..e046bbf6364 100644 --- a/backends/qualcomm/runtime/QnnExecuTorch.h +++ b/backends/qualcomm/runtime/QnnExecuTorch.h @@ -27,6 +27,16 @@ #define QNN_RUNTIME_LPAI_CORE_SELECTION "qnn_runtime_lpai_core_selection" #define QNN_RUNTIME_HEAP_PROFILING_PATH "qnn_runtime_heap_profiling_path" +#if defined(_MSC_VER) +#if defined(QNN_EXECUTORCH_BUILDING_DLL) +#define QNN_EXECUTORCH_EXPORT __declspec(dllexport) +#else +#define QNN_EXECUTORCH_EXPORT __declspec(dllimport) +#endif +#else +#define QNN_EXECUTORCH_EXPORT __attribute__((__visibility__("default"))) +#endif + #ifdef __cplusplus extern "C" { #endif // __cplusplus @@ -69,18 +79,18 @@ struct CustomMemTensorInfo { /// alignment as MemoryAllocator::kDefaultAlignment. /// See runtime/core/memory_allocator.h.

Instead this lowers standalone aten.sigmoid / aten.tanh / aten.silu to a single cortex_m.quantized_activation(input, lut) op backed by a 256-entry int8 LUT precomputed at AoT from the input/output qparams and the activation function. The kernel is a single byte-indexed lookup loop -- shape-agnostic, activation-agnostic, and free of any runtime requantization. Encoding the activation in the LUT bytes rather than a kind enum keeps the kernel surface to one op. For SiLU specifically, the LUT can encode `x * sigmoid(x)` directly, so the naive sigmoid-plus-elementwise-mul decomposition is unnecessary. aten.silu is added to the to_edge preserve_ops list so it doesn't decompose to sigmoid+mul before the lowering pass sees it; this is set globally because no per-test opt-out exists today. LUT-build numerics deliberately mirror the existing cortex_m CMSIS-NN conventions. Sigmoid/silu use a sign-branched stable form that always exponentiates a non-positive value, so the LUT build can't trip OverflowError for unusually wide input qparams. The final fp → int8 quantize uses round-half-away-from-zero, matching the rounding requantize_cmsis applies after its right-shift in passes_utils. ### Test plan In Silero VAD the final `sigmoid(final_conv(x))` now lowers; the 3 remaining sigmoids and 2 tanhs are LSTMCell gates and stay in aten because PyTorch export captures nn.LSTMCell as a single high-level op -- the quantizer never sees the gates and can't annotate them, and to_edge only decomposes the cell after the quantizer has run. test_lstm_cell.py captures the expected end-state as an xfail that will flip green once a pre-annotation decompose pass lands; that work is tracked as a separate follow-up. Other activations (GELU for KWT, Mish, ELU, Softplus) plug in as a few additional entries in passes_utils._ACTIVATION_FNS plus matching quantizer patterns. The generic op + LUT design carries them with no kernel changes. --------- Co-authored-by: Claude --- backends/cortex_m/CMakeLists.txt | 1 + .../cortex_m/ops/op_quantized_activation.cpp | 133 +++++++++++++++ backends/cortex_m/ops/operators.py | 29 ++++ backends/cortex_m/ops/operators.yaml | 6 + backends/cortex_m/ops/targets.bzl | 1 + .../passes/convert_to_cortex_m_pass.py | 43 ++++- backends/cortex_m/passes/passes_utils.py | 61 +++++++ .../cortex_m/quantizer/pattern_checkers.py | 19 +++ .../cortex_m/quantizer/quantizer_support.py | 8 + .../cortex_m/test/models/test_silero_vad.py | 20 ++- .../test/ops/test_activation_quant.py | 152 ++++++++++++++++++ backends/cortex_m/test/tester.py | 8 + 12 files changed, 475 insertions(+), 6 deletions(-) create mode 100644 backends/cortex_m/ops/op_quantized_activation.cpp create mode 100644 backends/cortex_m/test/ops/test_activation_quant.py diff --git a/backends/cortex_m/CMakeLists.txt b/backends/cortex_m/CMakeLists.txt index 627406c1935..f88a6306fed 100644 --- a/backends/cortex_m/CMakeLists.txt +++ b/backends/cortex_m/CMakeLists.txt @@ -81,6 +81,7 @@ set(_cortex_m_kernels__srcs ${CMAKE_CURRENT_SOURCE_DIR}/ops/op_minimum.cpp ${CMAKE_CURRENT_SOURCE_DIR}/ops/op_pad.cpp ${CMAKE_CURRENT_SOURCE_DIR}/ops/op_quantize_per_tensor.cpp + ${CMAKE_CURRENT_SOURCE_DIR}/ops/op_quantized_activation.cpp ${CMAKE_CURRENT_SOURCE_DIR}/ops/op_quantized_add.cpp ${CMAKE_CURRENT_SOURCE_DIR}/ops/op_quantized_avg_pool2d.cpp ${CMAKE_CURRENT_SOURCE_DIR}/ops/op_quantized_batch_matmul.cpp diff --git a/backends/cortex_m/ops/op_quantized_activation.cpp b/backends/cortex_m/ops/op_quantized_activation.cpp new file mode 100644 index 00000000000..d985c8484c9 --- /dev/null +++ b/backends/cortex_m/ops/op_quantized_activation.cpp @@ -0,0 +1,133 @@ +/* + * Copyright (c) Meta Platforms, Inc. and affiliates. + * All rights reserved. + * + * This source code is licensed under the BSD-style license found in the + * LICENSE file in the root directory of this source tree. + */ + +#include "cortex_m_ops_common.h" + +#include + +#if defined(__ARM_FEATURE_MVE) && (__ARM_FEATURE_MVE & 1) +#include +#define HAS_HELIUM_SIMD 1 +#endif + +#if defined(ARM_MATH_DSP) && !defined(HAS_HELIUM_SIMD) +#include +#define HAS_DSP_PACKED_LUT 1 +#endif + +namespace cortex_m { +namespace native { + +#if defined(HAS_DSP_PACKED_LUT) +// Local 4-byte read/write helpers.

Note that the timestamp-query measurements will be printed out and not included into `.etdp`. + +So, in this case the command is: + +```bash +EXECUTORCH_VGF_ENABLE_TIMESTAMP_QUERIES=1 \ +./cmake-out-vgf/executor_runner \ + --model_path vgf_mobilenetv2_out/mobilenet_v2_vgf_int8.pte \ + --num_executions 10 \ + --etdump_path ./etdumps/vgf_timestamps.etdp \ + --print_output none +``` + ## Help & Improvements If you have problems or questions, or have suggestions for ways to improve the Arm backend, please reach out diff --git a/backends/arm/runtime/VGFBackend.cpp b/backends/arm/runtime/VGFBackend.cpp index c7375c58b4c..0f6893d1dec 100644 --- a/backends/arm/runtime/VGFBackend.cpp +++ b/backends/arm/runtime/VGFBackend.cpp @@ -6,6 +6,9 @@ */ #include +#include +#include + using namespace std;

Previously, we were running calibration directly on the graph shaped for lowering (with fixed AR-N constraints). That forced us into an autoregressive loop (AR1 per step), which was both inefficient and slow since we never saw the full sequence context in a single pass. With this update, calibration is done once during the prefill stage using the full tokens chunk. This gives us much better coverage in a single run and completely removes the need for iterative decoding during calibration. After quantization, we take the KV cache encodings from the output, override the input KV cache encodings, and then propagate those into the graph that will later be lowered. This keeps everything consistent without needing to recalibrate on that graph.

The pybind _portable_lib thin-LTO link aborts with `LLVM gold plugin has failed to create LTO module: Invalid value (Producer: 'LLVM21.1.3-rust-1.92.0-stable' Reader: 'LLVM 12.0.1')`. Root cause: with `-DEXECUTORCH_BUILD_WEBGPU=ON` the backend static-links the prebuilt Rust `libwgpu_native.a`, whose objects embed LLVM-21 `.llvmbc` bitcode (377 of 487 archive members), into the thin-LTO'd pybind extension that pybind11 builds with the CI image's clang-12. LLVM-12's gold plugin cannot parse LLVM-21 bitcode, so the link fails before any test runs. Fix: link the prebuilt shared `libwgpu_native.so` (already downloaded by `setup-wgpu-native.sh`) instead of the static `.a`. The `.so` carries no `.llvmbc`, so no foreign bitcode enters the LTO link. This mirrors how the QNN/CoreML/OpenVINO backends consume prebuilt native deps (shared, runtime-loaded) rather than static-linking foreign objects. Also flips the setup-script idempotency check to the `.so`.

The op uses two or three execute nodes per dtype path that share a 6-binding descriptor set layout: a GEMM `DynamicDispatchNode` that self-gates to `{0,0,0}` at M==1, and an adaptive nc-coop GEMV sibling `DynamicDispatchNode` that self-gates to `{0,0,0}` at M!=1. The fp16 path adds a transpose preprocess that also self-gates at M==1. Decode-time `virtual_resize` correctly routes M==1 through the nc-coop GEMV after a prefill M>1 set up the graph. Existing serialized models that reference `et_vk.linear_q4gsw.default` are routed to the same forwarder so the cutover requires no graph-level changes; the old `QuantizedLinear.cpp::linear_q4gsw` body is deleted. Production shaders under `runtime/graph/ops/glsl/`: - `q4gsw_linear_gemm__w_4x8_nc` — fp32 GEMM, 4M x 8N per-thread tile, 8x8 LWG, reads the raw `[M, K]` activation directly. The per-k4 weight tile loads as a single `ivec4` covering 2 consecutive 4x4 N-blocks (one 16B aligned LSU read replaces two 8B reads). Aliases the same buffer the prepack writes. - `q4gsw_linear_gemm__tin__w_4x8_nc` — fp16 GEMM, transposed-input path, 8x4 per-thread tile, 1x128 LWG, reads the pre-transposed vec4 activation produced by the transpose preprocess. Nibble dequant stays in int16 end-to-end before the fp16 FMA, saving one fp32 register and lifting AOC fiber occupancy from 37% to 50% on Adreno 750 (validated at M=256 K=4096 N=4096: 6135.92 us -> 5637.20 us, -8.1% wall-clock). - `q4gsw_linear_gemv_coop__w_4x8_nc_buffer_{g1w64,g4w16,g8w8}` — cooperative-reduction GEMV reading the same nc-buffer weight payload as the GEMM shaders, with three (NUM_GROUPS, WORKERS_PER_GROUP) decompositions chosen at dispatch time by the production picker based on output N. All keep total threads/WG = 64; each WG produces NUM_GROUPS * 8 outputs, and the K-loop strides by WORKERS_PER_GROUP. Prepack: `pack_q4_linear_weight__w_4x8_nc_buffer` produces an int SOA nibble buffer; one `ivec4` covers a 4K x 8N block. The fp32 GEMM shader views the buffer as `ivec4`; the fp16 tin GEMM shader reads it as `ivec2`; the nc-coop GEMV shader rebinds the same bytes as scalar int arrays. Scales use a single `prepack_q4_scales` (dtype-matched vec4) for GEMM; GEMV rebinds the same bytes as a gvec2 via `vec_size=2`. The shared nc-buffer payload means prefill and decode both consume one prepack — no dual-format weight memory cost. Dispatch structure: - fp32 (`add_q4gsw_linear_w_4x8_node`): two nodes. The GEMM dispatch binds `q4gsw_linear_gemm__w_4x8_nc` unconditionally; its gated global WG gates the dispatch to `{0,0,0}` at M==1. The nc-coop GEMV sibling owns the decode. - fp16 (`add_q4gsw_linear_tin_w_4x8_node`): three nodes. The transpose preprocess self-gates `{0,0,0}` when M==1 (no-op); the GEMM dispatch binds `q4gsw_linear_gemm__tin__w_4x8_nc` and its gated global WG returns `{0,0,0}` at M==1; the nc-coop GEMV sibling handles M==1. - nc-coop GEMV picker (`add_q4gsw_linear_nc_coop_gemv_node`): shape-adaptive dispatch that self-gates `{0,0,0}` when M!=1. Heuristic on output N: * N <= 1024 -> `q4gsw_linear_gemv_coop__w_4x8_nc_buffer_g1w64` LWG (1, 1, 64) * N <= 4096 -> `q4gsw_linear_gemv_coop__w_4x8_nc_buffer_g4w16` LWG (1, 4, 16) * N > 4096 -> `q4gsw_linear_gemv_coop__w_4x8_nc_buffer_g8w8` LWG (1, 8, 8) The adaptive picker replaces sg-GEMV at decode. Cross-device sweep on Galaxy S24 (Adreno 750), S25 (Adreno 830), and Pixel 9 Pro XL (Mali-G715) shows shape-adaptive nc-coop beats sg-GEMV on every LLM-decode shape by 3-56%, with the largest wins at small-N (47-56% at K=2048 N=512 across both Adreno devices). The adaptive picker also unblocks Mali, where sg-GEMV cannot dispatch (subgroupSize=16 != required 64). The op is registered under both `et_vk.q4gsw_linear.default` and `et_vk.linear_q4gsw.default` for backward compatibility. Also extends `validate_against_reference` in `test/custom_ops/utils.cpp` to handle fp16 tensors. Demonstration shaders under `test/custom_ops/glsl/` (not linked into the production shader library): - `q4gsw_linear_gemv__w_4x8_nc{,_nosg}` — sg / nosg GEMV variants from earlier iterations. The sg variant pins subgroupSize to 64 via `VK_EXT_subgroup_size_control` and uses `subgroupBroadcast`; the nosg variant has every thread load its own activation. Both are dispatched by the `test_fpa_q4gsw_linear` benchmark binary's forced-shader selectors `GEMV_W_4X8` and `GEMV_W_4X8_NOSG` (selectors 1 and 2). Retained as a demonstration of the single-thread-per-output GEMV layout the adaptive nc-coop now supersedes at decode. Buffer-padding fix (latent OOB read on N % 8 != 0): The fp32 GEMM's 16B ivec4 weight load spans two consecutive (k4, n4) ivec2 tiles along N. Pad the SOA weight buffer's row stride to next-even N4 (no-op for the canonical N % 8 == 0 shapes); the prepack shader's existing `(n < N)` branch fills the OOB tiles with the bias-zero nibble pattern (0x88888888u). Adds GEMM accuracy coverage for N=12 and N=20. ghstack-source-id: 390109017 @exported-using-ghexport Differential Revision: [D107447239](https://our.internmc.facebook.com/intern/diff/D107447239/) --- .../glsl/pack_q4_linear_weight__w_4x8.glsl | 179 ++++ .../glsl/pack_q4_linear_weight__w_4x8.yaml | 22 + .../glsl/q4gsw_linear_gemm__tin__w_4x8.glsl | 333 +++++++ .../glsl/q4gsw_linear_gemm__tin__w_4x8.yaml | 34 + .../ops/glsl/q4gsw_linear_gemm__w_4x8.glsl | 316 +++++++ .../ops/glsl/q4gsw_linear_gemm__w_4x8.yaml | 29 + .../glsl/q4gsw_linear_gemv_coop__w_4x8.glsl | 324 +++++++ .../glsl/q4gsw_linear_gemv_coop__w_4x8.yaml | 41 + .../transpose_cast_contig_to_vectorized.glsl | 67 ++ .../transpose_cast_contig_to_vectorized.yaml | 26 + ...anspose_cast_contig_to_vectorized_4x4.glsl | 89 ++ ...anspose_cast_contig_to_vectorized_4x4.yaml | 25 + .../runtime/graph/ops/impl/Preprocess.cpp | 117 +++ .../runtime/graph/ops/impl/Preprocess.h | 29 + .../runtime/graph/ops/impl/Q4gswLinear.cpp | 682 ++++++++++++++ .../runtime/graph/ops/impl/Q4gswLinear.h | 120 +++ .../graph/ops/impl/QuantizedLinear.cpp | 31 - .../vulkan/runtime/graph/ops/impl/Staging.cpp | 2 +- .../vulkan/runtime/graph/ops/impl/Staging.h | 6 + .../runtime/graph/ops/impl/Transpose.cpp | 6 +- .../glsl/q4gsw_linear_gemv__w_4x8.glsl | 371 ++++++++ .../glsl/q4gsw_linear_gemv__w_4x8.yaml | 40 + .../custom_ops/impl/TestFpaQ4gswLinear.cpp | 867 ++++++++++++++++++ backends/vulkan/test/custom_ops/targets.bzl | 1 + .../test/custom_ops/test_fpa_q4gsw_linear.cpp | 548 +++++++++++ backends/vulkan/test/custom_ops/utils.cpp | 8 +- 26 files changed, 4274 insertions(+), 39 deletions(-) create mode 100644 backends/vulkan/runtime/graph/ops/glsl/pack_q4_linear_weight__w_4x8.glsl create mode 100644 backends/vulkan/runtime/graph/ops/glsl/pack_q4_linear_weight__w_4x8.yaml create mode 100644 backends/vulkan/runtime/graph/ops/glsl/q4gsw_linear_gemm__tin__w_4x8.glsl create mode 100644 backends/vulkan/runtime/graph/ops/glsl/q4gsw_linear_gemm__tin__w_4x8.yaml create mode 100644 backends/vulkan/runtime/graph/ops/glsl/q4gsw_linear_gemm__w_4x8.glsl create mode 100644 backends/vulkan/runtime/graph/ops/glsl/q4gsw_linear_gemm__w_4x8.yaml create mode 100644 backends/vulkan/runtime/graph/ops/glsl/q4gsw_linear_gemv_coop__w_4x8.glsl create mode 100644 backends/vulkan/runtime/graph/ops/glsl/q4gsw_linear_gemv_coop__w_4x8.yaml create mode 100644 backends/vulkan/runtime/graph/ops/glsl/transpose_cast_contig_to_vectorized.glsl create mode 100644 backends/vulkan/runtime/graph/ops/glsl/transpose_cast_contig_to_vectorized.yaml create mode 100644 backends/vulkan/runtime/graph/ops/glsl/transpose_cast_contig_to_vectorized_4x4.glsl create mode 100644 backends/vulkan/runtime/graph/ops/glsl/transpose_cast_contig_to_vectorized_4x4.yaml create mode 100644 backends/vulkan/runtime/graph/ops/impl/Preprocess.cpp create mode 100644 backends/vulkan/runtime/graph/ops/impl/Preprocess.h create mode 100644 backends/vulkan/runtime/graph/ops/impl/Q4gswLinear.cpp create mode 100644 backends/vulkan/runtime/graph/ops/impl/Q4gswLinear.h create mode 100644 backends/vulkan/test/custom_ops/glsl/q4gsw_linear_gemv__w_4x8.glsl create mode 100644 backends/vulkan/test/custom_ops/glsl/q4gsw_linear_gemv__w_4x8.yaml create mode 100644 backends/vulkan/test/custom_ops/impl/TestFpaQ4gswLinear.cpp create mode 100644 backends/vulkan/test/custom_ops/test_fpa_q4gsw_linear.cpp diff --git a/backends/vulkan/runtime/graph/ops/glsl/pack_q4_linear_weight__w_4x8.glsl b/backends/vulkan/runtime/graph/ops/glsl/pack_q4_linear_weight__w_4x8.glsl new file mode 100644 index 00000000000..f70b5a70e33 --- /dev/null +++ b/backends/vulkan/runtime/graph/ops/glsl/pack_q4_linear_weight__w_4x8.glsl @@ -0,0 +1,179 @@ +/* + * Copyright (c) Meta Platforms, Inc. and affiliates. + * All rights reserved. + * + * This source code is licensed under the BSD-style license found in the + * LICENSE file in the root directory of this source tree. + */ + +#version 450 core + +#define PRECISION ${PRECISION} + +#define STORAGE ${STORAGE} + +layout(std430) buffer; + +// Output: W_4X8 block-packed nibble weight, written as 4K x 8N blocks.

That misclassified files with includes such as arm_neon.h as having an Arm header, then failed them when the current Arm year was absent. Match the actual Arm copyright line instead so non-Arm headers are skipped while real Arm headers still get the year check.

From: Oscar Andersson <87121123+oscarandersson8218@users.noreply.github.com> Date: Fri, 5 Jun 2026 12:18:49 +0200 Subject: [PATCH 191/317] Arm backend: Complete TOSA dialect shape ops (#20062) Add fake-kernel support for the remaining TOSA shape operators: SLICE_SHAPE, EXP2_SHAPE, LOG2_CEIL_SHAPE, LOG2_FLOOR_SHAPE, MAX_SHAPE, MIN_SHAPE, DIV_CEIL_SHAPE, and ASSERT_EQUAL_SHAPE. Tighten shape-op validation to better match the TOSA spec. DIM now validates supported dtypes and rejects non-positive dimensions, and EXP2_SHAPE enforces MAX_LOG2_SIZE including the 8k-level bound. Make ASSERT_EQUAL_SHAPE use ShapeEnv bounds to reject provably mismatched symbolic dimensions without relying on SymBool truthiness. Add regression coverage for invalid CONCAT_SHAPE inputs, DIM dtype and zero-dimension failures, EXP2_SHAPE bound checks, disjoint symbolic ASSERT_EQUAL_SHAPE mismatches, CONST_SHAPE on non-shape specs, and bounded-symbolic SLICE_SHAPE behavior. cc @digantdesai @freddan80 @per @zingo @mansnils @Sebastian-Larsson @robell @rascani Signed-off-by: Oscar Andersson ---

Each header embeds the shader verbatim (`inline constexpr const char* kWGSL = R"(...)";` plus the workgroup-size constants) and a `// wgsl-sha256:` of the source; `--check` (wired into `test_build_webgpu.sh` and the `webgpu_backend` CMake build) and the unit tests fail the build if any committed header drifts. `workgroup_size` is parsed for all three dims (WGSL allows 1-3; y and z default to 1), emitting `kWorkgroupSizeX/Y/Z` so future 2D/3D shaders need no codegen change; the two current 1D consumers read `...X`. The X/Y/Z naming and `uint32_t`-per-axis mirror Vulkan's `utils::WorkgroupSize` (`backends/vulkan/runtime/utils/VecUtils.h`); WGSL `workgroup_size` is compile-time, so the value is parsed from the shader rather than set via runtime spec-constants as in Vulkan. The drift check compares the full rendered header (not just the shader sha), so a generator-logic change is also detected/regenerated. The parser accepts the spaced form `workgroup_size (n)` and suffix-typed literals (`64u`). Regenerates the two existing committed op headers: `binary_add_wgsl.h` and `rms_norm_wgsl.h` gain the `...X/Y/Z` constants (X = the 1D size, Y=Z=1); `rms_norm.wgsl` also drops its now-obsolete 3-line "keep in sync by hand" note (codegen + `--check` make it false). The shader code itself is unchanged. This change was authored with assistance from Claude.

Those two macros are used as expressions in 100+ call sites across fbcode/xplat/arvr, so that change broke many unrelated targets. This instead: - Keeps the MSVC fixes from #19686 (designated initializers, __declspec, statement-expression removal in Qualcomm code, etc.). - Restores ET_UNWRAP (result.h) and ET_UNWRAP_TOKENIZER (extension/llm/runner/ util.h) to their original expression forms, so existing call sites are unchanged. - Adds portable, MSVC-safe statement macros ET_ASSIGN_OR_RETURN and ET_ASSIGN_OR_RETURN_TOKENIZER for code that must build under MSVC. - Points the Qualcomm oss_scripts runner sites at the new macros.

A runner built for one target could therefore be used to run another target's program, silently producing wrong results. Build each target's runner into a target-suffixed directory and resolve the ELF by the test's target. The Arm Serialize/runner_utils ELF lookup gains an optional, defaulted build_dir_suffix so existing Arm-backend corstone tests are unaffected; CortexMSerialize passes the target's canonical cortex-m string. A target whose runner has not been built now fails with a clear FileNotFoundError naming the missing directory instead of running on a mismatched binary. ### Test plan ``` ./backends/cortex_m/test/build_test_runner.sh --target=cortex-m0plus ./backends/cortex_m/test/build_test_runner.sh --target=cortex-m7 ``` Authored with Claude Code. cc @digantdesai @freddan80 @per @zingo @oscarandersson8218 @mansnils @Sebastian-Larsson @robell --- backends/arm/test/runner_utils.py | 19 ++++++++++++++----- backends/arm/test/tester/serialize.py | 9 ++++++++- backends/cortex_m/target_config.py | 8 +++++++- backends/cortex_m/test/build_test_runner.sh | 2 +- backends/cortex_m/test/tester.py | 15 ++++++++++++--- examples/arm/run.sh | 8 ++++---- 6 files changed, 46 insertions(+), 15 deletions(-) diff --git a/backends/arm/test/runner_utils.py b/backends/arm/test/runner_utils.py index e41cfdbd810..13d42e222a4 100644 --- a/backends/arm/test/runner_utils.py +++ b/backends/arm/test/runner_utils.py @@ -892,7 +892,7 @@ def _elf_search_roots() -> list[Path]: def _elf_path_candidates( - target_board: str, use_portable_ops: bool = False + target_board: str, use_portable_ops: bool = False, build_dir_suffix: str = "" ) -> list[Path]: if target_board not in VALID_TARGET: raise ValueError(f"Unsupported target: {target_board}") @@ -901,11 +901,14 @@ def _elf_path_candidates( if target_board in ("corstone-300", "corstone-320"): build_dir = Path( "arm_test", - f"arm_semihosting_executor_runner_{portable_ops_str}{target_board}", + f"arm_semihosting_executor_runner_" + f"{portable_ops_str}{target_board}{build_dir_suffix}", ) binary_name = "arm_executor_runner" else: - build_dir = Path("arm_test", f"arm_executor_runner_{portable_ops_str}vkml") + build_dir = Path( + "arm_test", f"arm_executor_runner_{portable_ops_str}vkml{build_dir_suffix}" + ) binary_name = "executor_runner" candidates: list[Path] = [] @@ -950,9 +953,15 @@ def _resolve_existing_elf_path(elf_candidates: Iterable[Path]) -> Path: ) -def get_elf_path(target_board: str, use_portable_ops: bool = False) -> str: +def get_elf_path( + target_board: str, use_portable_ops: bool = False, build_dir_suffix: str = "" +) -> str: elf_path = _resolve_existing_elf_path( - _elf_path_candidates(target_board, use_portable_ops=use_portable_ops) + _elf_path_candidates( + target_board, + use_portable_ops=use_portable_ops, + build_dir_suffix=build_dir_suffix, + ) ) return str(elf_path) diff --git a/backends/arm/test/tester/serialize.py b/backends/arm/test/tester/serialize.py index 5cb511c9d79..d1a53ce004f 100644 --- a/backends/arm/test/tester/serialize.py +++ b/backends/arm/test/tester/serialize.py @@ -34,6 +34,7 @@ def __init__( module: Optional[torch.nn.Module], use_portable_ops: bool = False, timeout: int = 120, + build_dir_suffix: str = "", ): """ Args: @@ -41,6 +42,9 @@ def __init__( module: Original Module to be used for serialization.

For example, Torch-TensorRT's `output_format="executorch"` uses ExecuTorch only to export and runs the result with its own runtime. The minimal wheel: - omits runtime pybindings, kernels, backend packages, headers, examples, and devtools; - declares only the dependencies the export path needs (`flatbuffers`, `numpy`, `packaging`, `pyyaml`, `ruamel.yaml`, `sympy`, `tabulate`, `typing-extensions`) instead of the full set (`coremltools`, `scikit-learn`, `pandas`, `hydra-core`, `omegaconf`, and so on), so a normal install stays small; - produces byte-identical `.pte` output to the full wheel. The default (non-minimal) wheel is unchanged: its dependencies move from static `pyproject.toml` to a dynamic `install_requires` in `setup.py`, but the declared set is identical. Build from source and bundle it: ``` EXECUTORCH_BUILD_MINIMAL=1 pip wheel . --no-deps # or: EXECUTORCH_BUILD_MINIMAL=1 pip install . ``` A redistributor (e.g. NVIDIA, for a Torch-TensorRT container) can build the slim wheel at a pinned ExecuTorch version and ship it. `torch` is consumer-provided in both modes. CI (`test-minimal-wheel-linux`) builds the minimal wheel, asserts the excluded runtime/backend content and heavy deps are absent, installs it in a clean venv with full dependency resolution (no `--no-deps`), runs the bundled `flatc`, and exports MobileNetV2 to a `.pte`. Local result: minimal Linux x86_64 wheel ~2.1 MiB compressed vs ~15 MiB for the full wheel; MobileNetV2 `.pte` is 13,995,880 bytes, byte-identical to the published 1.3.1 wheel. --------- Co-authored-by: shoumikhin --- .ci/scripts/test_minimal_wheel.sh | 165 ++++++++++ .github/workflows/pull.yml | 30 ++ README-wheel.md | 10 + exir/_serialize/_flatbuffer.py | 48 +-- pyproject.toml | 32 +- setup.py | 487 ++++++++++++++++++++---------- 6 files changed, 571 insertions(+), 201 deletions(-) create mode 100755 .ci/scripts/test_minimal_wheel.sh diff --git a/.ci/scripts/test_minimal_wheel.sh b/.ci/scripts/test_minimal_wheel.sh new file mode 100755 index 00000000000..6c11cfc983f --- /dev/null +++ b/.ci/scripts/test_minimal_wheel.sh @@ -0,0 +1,165 @@ +#!/bin/bash +# Copyright (c) Meta Platforms, Inc. and affiliates. +# All rights reserved. +# +# This source code is licensed under the BSD-style license found in the +# LICENSE file in the root directory of this source tree. + +set -euxo pipefail + +PYTHON_EXECUTABLE="${PYTHON_EXECUTABLE:-python}" +REPO_ROOT="$(cd "$(dirname "${BASH_SOURCE[0]}")/../.." && pwd)" +BUILD_VENV="${REPO_ROOT}/.venv-minimal-build" +TEST_VENV="${REPO_ROOT}/.venv-minimal-test" + +rm -rf "${BUILD_VENV}" "${TEST_VENV}" "${REPO_ROOT}/dist" "${REPO_ROOT}/pip-out" + +"${PYTHON_EXECUTABLE}" -m venv "${BUILD_VENV}" +source "${BUILD_VENV}/bin/activate" +python -m pip install --upgrade pip +python -m pip install \ + "cmake>=3.24,<4.0.0" \ + "numpy>=2.0.0" \ + packaging \ + pyyaml \ + setuptools \ + wheel \ + zstd \ + certifi \ + torch \ + torchvision \ + --index-url https://download.pytorch.org/whl/cpu \ + --extra-index-url https://pypi.org/simple + +( + cd "${REPO_ROOT}" + EXECUTORCH_BUILD_MINIMAL=1 python setup.py bdist_wheel +) + +WHEEL_FILE="$(find "${REPO_ROOT}/dist" -maxdepth 1 -name 'executorch-*.whl' | head -1)" +test -n "${WHEEL_FILE}" + +python - "${WHEEL_FILE}" <<'PY' +import re +import sys +import zipfile + +wheel_file = sys.argv[1] +with zipfile.ZipFile(wheel_file) as wheel: + names = wheel.namelist() + metadata_name = next( + (name for name in names if name.endswith(".dist-info/METADATA")), None + ) + if metadata_name is None: + raise AssertionError(f"{wheel_file} has no METADATA") + metadata_text = wheel.read(metadata_name).decode("utf-8") + +for forbidden in ( + "executorch/backends/", + "executorch/examples/", + "executorch/kernels/", + "executorch/runtime/", + "executorch/devtools/", + "executorch/extension/pybindings/", +): + matches = [name for name in names if name.startswith(forbidden)] + if matches: + raise AssertionError(f"{wheel_file} unexpectedly contains {matches[:5]}") + +extensions = [ + name + for name in names + if name.endswith((".so", ".dylib", ".dll", ".pyd")) and "flatc" not in name +] +if extensions: + raise AssertionError(f"{wheel_file} unexpectedly contains extensions: {extensions}") + + +def _dist_name(requirement): + name = re.split(r"[ ;\[<>=!~(]", requirement.strip(), maxsplit=1)[0] + return re.sub(r"[-_.]+", "-", name).lower() + + +# Only the core (non-extra) Requires-Dist entries define what a plain +# "pip install" pulls; ignore the optional extras (cortex_m, vgf, ...). +declared = { + _dist_name(line.split(":", 1)[1]) + for line in metadata_text.splitlines() + if line.startswith("Requires-Dist:") and "extra==" not in line.replace(" ", "") +} +# The minimal wheel must declare EXACTLY this core set and nothing else -- the +# same names as `keep` in setup.py:_minimal_dependencies().

0881b22b84628a2d1d0229fd25ab800171730a36 Mon Sep 17 00:00:00 2001 From: Martin Pavella Date: Mon, 8 Jun 2026 13:42:10 +0200 Subject: [PATCH 205/317] NXP backend: Update eIQ Neutron SDK to 3.1.2 (#19938) ### Summary This PR updates the Neutron SDK to the most recent version (3.1.2). This version removes the old conversion flow and forces the use of the new MLIR flow. This change is reflected in ExecuTorch NXP backend by the removal of the `use_new_flow_neutron_c` flag. ### Test plan Tested by all NXP backend tests. cc @robert-kalmar @JakeStevens @digantdesai @rascani --- .../ops_converters/abs_converter.py | 14 +- .../adaptive_avg_pool_2d_converter.py | 29 +- .../ops_converters/add_tensor_converter.py | 39 +-- .../ops_converters/avg_pool_2d_converter.py | 21 +- .../ops_converters/clamp_converter.py | 27 +- .../constant_pad_nd_converter.py | 36 +- .../ops_converters/leaky_relu_converter.py | 22 +- .../max_pool2d_with_indices_converter.py | 56 +--- .../ops_converters/mean_dim_converter.py | 81 ++--- .../ops_converters/mul_tensor_converter.py | 47 +-- .../ops_converters/sigmoid_converter.py | 23 +- .../ops_converters/slice_tensor_converter.py | 85 +---- .../ops_converters/sub_tensor_converter.py | 39 +-- .../ops_converters/tanh_converter.py | 17 +- .../upsample_bilinear2d_converter.py | 60 ++-- .../upsample_nearest2d_converter.py | 47 +-- .../nxp/backend/neutron_converter_manager.py | 5 -

Larger windows were more +expensive in runtime and stalled in our experiments, while smaller windows were +easier to validate earlier but produced weaker prompts and less representative +perplexity results. This branch also does not use KV-cache decoding, so every +generated token recomputes attention across the whole window and larger sequence +lengths become even more costly. If KV-cache support is added later, it should +reduce the incremental decode cost, but it is not the direct reason seq32 was +chosen here. + +## 0.

This + is the current validated path for meaningful output in this example. +- `max_seq_length=32` and `calibration_seq_length=32` are kept equal so the + quantizer observes the same token-window shape that the runtime will execute. + Keeping them aligned avoids calibrating a shape that the deployed runner never + uses. +- `calibration_limit=62` is the current fuller-calibration setting for this + README. With the newer full-logits calibration path, larger limits are now + practical enough to use by default. For quicker iteration, `calibration_limit=2` + is the fast validation setting discussed later in this document. + +## 3. Export the generation artifact + +This command produces the full-logits PTE used for the generation smoke test and optional perplexity evaluation.

They are simply the validated pool +sizes for this example's seq32 embedded-PTE runner. Start with them unless you +are actively changing the export shape or runtime integration. + +## 5. Run a generation smoke test + +Use `generate_sampled.py` to tokenize the prompt on the host, write the input +tensor file expected by the semihosting runner, launch FVP, read back the +output logits, and decode the generated token IDs into text: + +```bash +python examples/arm/smollm2_example_ethos_u/generate_sampled.py \ + --fvp examples/arm/arm-scratch/FVP-corstone320/models/Linux64_GCC-9.3/FVP_Corstone_SSE-320 \ + --runner smollm2_ethosu_seq32_w8a16_wikitext_full_logits/cmake-out/arm_executor_runner \ + --embedded-pte \ + --tokenizer data/tokenizers/smollm2/tokenizer.json \ + --prompt "Once upon a time in a small village," \ + --window 32 \ + --max-new-tokens 2 \ + --full-logits \ + --temperature 0 \ + --top-p 0.9 \ + --repetition-penalty 1.1 +``` + +How to interpret the main options: + +- `--embedded-pte` tells the script not to copy a separate `program.pte`, + because the runner already contains the model. +- `--window 32` must match the exported `max_seq_length`. If these differ, the + runner will reject the input tensor shape. +- `--max-new-tokens 2` keeps the smoke test short. The goal here is to show the + end-to-end path works, not to benchmark long decoding. +- `--full-logits` tells `generate_sampled.py` to select the last valid prompt + row from the `[window, vocab]` output. This matches the calibrated static + non-KV export path and avoids sampling from padded positions. +- `--temperature 0` switches to greedy decoding, which is the most stable way + to compare short smoke runs. +- `--top-p 0.9` is kept for consistency with the broader sampling interface, + but it does not affect greedy decoding when `--temperature 0`. +- `--repetition-penalty 1.1` still matters in greedy mode because it modifies + the logits before `argmax`. + +## 6.

Lower this value + when you want a quicker but noisier local check. + +The evaluator script compares two runners, which is why it asks for both +`--runner-w8a8` and `--runner-w8a16`. In this simplified `w8a16`-only flow, it +is acceptable to pass the same runner to both options when you only want one +number from the validated artifact. + +## 7. Additional notes + +### Why padding is needed for full-logits evaluation + +The full-logits export returns one logits row per position in the fixed window. +Short prompts therefore need padding so the runtime still receives a tensor with +exactly 32 token slots. For perplexity, the evaluator right-pads the prompt so +the real tokens stay at the front of the causal window and each target token is +scored against the matching row. This preserves the usual left-to-right causal +ordering even though the deployed runtime works with fixed-size inputs. + +### What `full` quantization scope means + +`quantization.quantize_scope=full` asks the export stack to quantize more than +just the linear layers. That path exists for experimentation, but it is not the +validated path in this README because the linear-only setup is the one that +currently produces the clearest end-to-end result on Ethos-U FVP. + +### Can calibration be faster? + +Yes. The quickest way to iterate is to lower `--calibration_limit`. The tradeoff +is that you are collecting activation statistics from fewer samples, which can +hurt perplexity and generation quality. Keep `--calibration_seq_length` aligned +with `--max_seq_length`; if they differ, the calibration run is no longer +measuring the same tensor shapes that the deployed model will execute. In the +older non-KV path, calibration was especially slow because it often replayed +many partial prefixes position by position. The newer full-logits path can +observe a whole 32-token window in one pass, so larger limits are now much more +practical. + +In the saved seq32 runs in this branch, `--calibration_limit=62` is now +bearable as the fuller-calibration setting, while `--calibration_limit=2` +remains the fast validation option. On the 100-prompt perplexity check, `2` +scored best, but `62` was still competitive and is the more conservative +default when export turnaround is less important than fuller calibration. + +### Historical seq8 artifacts + +Earlier experiments in this directory used smaller seq8 exports and separate +included-PTE runners. They are useful as implementation history, but they are +not the main path for this README because they add options without improving the +clarity of the validated seq32 `w8a16` workflow. + +### Clean-checkout checklist + +If the example fails on a clean checkout, the most common missing pieces are: + +- `huggingface_hub[cli]` for the `hf download` command. +- `datasets` for rebuilding Wikitext prompts in the perplexity script. +- `pytorch_tokenizers`, installed from `./extension/llm/tokenizers/`. +- `backends/arm/scripts/build_executorch.sh`, which populates the default + `arm_test` build root used by the runner wrappers. diff --git a/examples/arm/smollm2_example_ethos_u/build_executor_runner_fvp.sh b/examples/arm/smollm2_example_ethos_u/build_executor_runner_fvp.sh new file mode 100644 index 00000000000..b28bdafbaa8 --- /dev/null +++ b/examples/arm/smollm2_example_ethos_u/build_executor_runner_fvp.sh @@ -0,0 +1,76 @@ +#!/usr/bin/env bash +# Copyright 2026 Arm Limited and/or its affiliates. +# +# This source code is licensed under the BSD-style license found in the +# LICENSE file in the root directory of this source tree. + +set -euo pipefail + +script_dir=$(cd -- "$( dirname -- "${BASH_SOURCE[0]}" )" &> /dev/null && pwd) +repo_root=$(cd "${script_dir}/../../.." && pwd) + +pte_file="" +et_build_root="${repo_root}/arm_test" +output_dir="" +toolchain="arm-none-eabi-gcc" +target="ethos-u85-256" +system_config="Ethos_U85_SYS_DRAM_High" +memory_mode="Dedicated_Sram_512KB" + +usage() { + cat <&2 + usage + exit 1 + ;; + esac +done + +if [[ -z "${pte_file}" ]]; then + echo "--pte is required" >&2 + exit 1 +fi + +cmd=( + bash "${repo_root}/backends/arm/scripts/build_executor_runner.sh" + --et_build_root=${et_build_root} + --pte=${pte_file} + --build_type=Release + --target=${target} + --system_config=${system_config} + --memory_mode=${memory_mode} + --extra_build_flags=-DET_ARM_BAREMETAL_SCRATCH_TEMP_ALLOCATOR_POOL_SIZE=0x02000000 + --ethosu_tools_dir=${repo_root}/examples/arm/arm-scratch + --toolchain=${toolchain} +) + +if [[ -n "${output_dir}" ]]; then + cmd+=(--output=${output_dir}) +fi + +cd "${repo_root}" +"${cmd[@]}" diff --git a/examples/arm/smollm2_example_ethos_u/build_executor_runner_semihosting.sh b/examples/arm/smollm2_example_ethos_u/build_executor_runner_semihosting.sh new file mode 100644 index 00000000000..1ed42eed14f --- /dev/null +++ b/examples/arm/smollm2_example_ethos_u/build_executor_runner_semihosting.sh @@ -0,0 +1,78 @@ +#!/usr/bin/env bash +# Copyright 2026 Arm Limited and/or its affiliates. +# +# This source code is licensed under the BSD-style license found in the +# LICENSE file in the root directory of this source tree. + +set -euo pipefail + +script_dir=$(cd -- "$( dirname -- "${BASH_SOURCE[0]}" )" &> /dev/null && pwd) +repo_root=$(cd "${script_dir}/../../.." && pwd) + +et_build_root="${repo_root}/arm_test" +output_dir="${repo_root}/cmake-out-smollm2-ethosu-semi" +toolchain="arm-none-eabi-gcc" +pte_file="" +target="ethos-u85-256" +system_config="Ethos_U85_SYS_DRAM_High" +memory_mode="Dedicated_Sram_512KB" +method_pool_size="0x00800000" +scratch_pool_size="0x00400000" +input_file_pool_size="0x00100000" + +usage() { + cat <&2 + usage + exit 1 + ;; + esac +done + +cd "${repo_root}" +pte_arg="semihosting" +if [[ -n "${pte_file}" ]]; then + pte_arg="${pte_file}" +fi + +bash "${repo_root}/backends/arm/scripts/build_executor_runner.sh" \ + --et_build_root="${et_build_root}" \ + --output="${output_dir}" \ + --pte="${pte_arg}" \ + --build_type=Release \ + --target="${target}" \ + --system_config="${system_config}" \ + --memory_mode="${memory_mode}" \ + --extra_build_flags="-DSEMIHOSTING=ON -DFETCHCONTENT_UPDATES_DISCONNECTED=ON -DFETCHCONTENT_FULLY_DISCONNECTED=ON -DET_ARM_BAREMETAL_METHOD_ALLOCATOR_POOL_SIZE=${method_pool_size} -DET_ARM_BAREMETAL_SCRATCH_TEMP_ALLOCATOR_POOL_SIZE=${scratch_pool_size} -DET_ARM_BAREMETAL_SEMIHOSTING_FILE_ALLOCATOR_POOL_SIZE=${input_file_pool_size}" \ + --ethosu_tools_dir="${repo_root}/examples/arm/arm-scratch" \ + --toolchain="${toolchain}" diff --git a/examples/arm/smollm2_example_ethos_u/default_prompts.txt b/examples/arm/smollm2_example_ethos_u/default_prompts.txt new file mode 100644 index 00000000000..1322f0dfe8f --- /dev/null +++ b/examples/arm/smollm2_example_ethos_u/default_prompts.txt @@ -0,0 +1,9 @@ +Once upon a time in a small village, +The future of artificial intelligence is +To solve climate change, we need to +In the year 2050, humanity will +The most important lesson I learned was +Write a short story about a robot: +Explain quantum computing in simple terms: +List three benefits of renewable energy: +What's the capital of France?

Mirrored in fbcode and xplat. Also replaces the two device-transfer helpers `clone_tensor_ptr_to_device` and `clone_tensor_ptr_to_cpu` with a single `clone_tensor_ptr_to(tensor, target)` keyed on the target device. The direction (host-to-device or device-to-host) is inferred from the source and target, which removes the asymmetry where one helper named the device and the other inferred it, and removes the footgun where `clone_tensor_ptr_to_device(t, CPU)` aborted. CPU-to-CPU and device-to-device are rejected with clear messages; `clone_tensor_ptr` remains the same-device copy and the `make_tensor_ptr` device tag is unchanged. This mirrors ATen's single `to(device)` and keeps the public surface minimal. The `extension-tensor.md` guide and its ATen equivalence table are updated to match. This also fixes a pre-existing portable-build break: the aliasing `make_tensor_ptr(const Tensor&)` overload passed `device_type()` and `device_index()` as two separate arguments to a primary factory that takes a single `Device`, so the non-`USE_ATEN_LIB` build did not compile; it now wraps them in a `Device`.

charset=UTF-8 Content-Transfer-Encoding: 8bit Summary: `AotiPartitioner.partition` tagged every `call_function` node, including `executorch_call_delegate` calls already lowered by an earlier partitioner. So when `CudaPartitioner` runs as a second partitioner — e.g. after a TensorRT partition in a stacked `.pte` where TensorRT lowers the ops it can and the CUDA backend handles the rest — it tried to re-delegate the foreign delegate node, producing a malformed nested delegate. This is the blocker to composing the two backends in one `.pte`. Tag only the non-lowered nodes, reusing the existing `get_non_lowered_nodes` helper (which already excludes `executorch_call_delegate` calls and their output getitems), so the partitioner claims just the remaining ops and composes cleanly after another backend. In the single-partitioner case there are no delegate nodes, so `get_non_lowered_nodes` returns every `call_function` and behavior is unchanged. The same composition gap existed for constants: the final loop tagged every untagged param/buffer/lifted constant with this partition's tag, including ones consumed only by the foreign delegate. Backend lowering rejected those, since it requires every user of a tagged constant to share that tag while the foreign delegate's call keeps the prior one. Now only genuinely unused constants are tagged here — `tag_constant_data` already claims the ones this partition uses, and a constant feeding only a prior delegate is left untagged. Mirrored in fbcode and xplat.

Also shrinks the exported `.pte` (and its in-memory footprint) by de-duplicating repeated kernel source blobs. **New custom kernel ops** (`backends/mlx/custom_kernel_ops/gguf/`) The `gguf/` package is organized as format routers over per-format implementations, so new GGUF formats (e.g. Q4_K) can be added without touching the op definitions: - `gguf/linear.py` / `gguf/embedding.py`: thin **format routers** — each owns the op identity (`mlx::gguf_linear` / `mlx::gguf_embedding`: custom op, fake, and lowering registration) and dispatches on the `format` arg. Only `"q6k"` is supported today; other formats raise `NotImplementedError`. - `gguf/q6k/common.py`: shared Q6_K primitives — constants, the pure-torch `dequantize_q6_k` reference, and the Metal header (`block_q6_K` struct + dequant helpers). Lightweight (no builder import), re-exported from `gguf/q6k/__init__.py`. - `gguf/q6k/linear.py`: `out = x @ dequant(weight)^T (+bias)` against a raw GGUF `block_q6_K` blob (no repacking). Emits two Metal kernels — a fused mat-vec for decode (`M==1`, ported from llama.cpp `kernel_mul_mv_q6_K_f32_impl`) and a tiled simdgroup mat-mat for prefill (`M>1`). For dynamic/symbolic `M`, both chains are emitted and selected at runtime via a new `IfNode`. - `gguf/q6k/embedding.py`: gather counterpart that dequantizes Q6_K rows directly. **Runtime / schema** New `IfNode` in `schema.fbs` (runtime conditional selecting one of two instruction chains on an integer condition) plus `exec_if` dispatch in `MLXInterpreter.h`. **Serialization: smaller `.pte` + lower load-time RAM** - Serializer de-duplicates identical strings into a single FlatBuffer offset (shared-string emission in the generated serializers / `generate.py` / `mlx_graph_serialize.py`). The big repeated `MetalKernelNode` source/header blobs are now written once. On Gemma 4 31B this cut the MLX graph metadata from ~1.23 MiB to ~0.47 MiB (~62%). - Loader interns those shared blobs into one `std::shared_ptr` keyed by the FlatBuffer string pointer (`StringPool` in `MLXLoader.{h,cpp}.tmpl`; `MLXInterpreter.h` derefs the handle), so a newly-produced `.pte` also uses less RAM at runtime. - Fully backward-compatible: no schema/format change. Old `.pte` files load unchanged (just without the dedup). **Gemma 4 31B GGUF loader** (`examples/models/gemma4_31b/`) - `iter_gguf_tensors` now yields the tensor's quant type and can emit Q6_K tensors as the raw `(N, n_blocks*210)` uint8 blob (`q6k_raw`); added `_raw_q6_k` helper and made `_unpack_q6_k` accept an already-materialized tensor. - New `mlx_gguf_linear.py` carrier modules (`GGUFLinear`/`GGUFEmbedding`) and `_handle_mlx_q6k` routing: Linear weights → `gguf_linear`, token embedding → `gguf_embedding`, tied lm_head reuses the embedding blob via `gguf_linear`, with a quantized-tensor fallback for any other Q6_K module. - Removed the `ET_MLX_ALLOW_NON_FUSED_QUANTIZED_OPS` env-var workaround in `export.py` since the fused path no longer needs it. **Refactor** - Renamed `backends/mlx/model_ops/` → `backends/mlx/custom_kernel_ops/` (with a `test/` subpackage) and updated all imports (`turboquant_cache.py`, `qwen3_5_moe/mlx_source_transformations.py`). ### Test plan - New/updated unit tests: `custom_kernel_ops/gguf/test/test_linear.py`, `test_embedding.py`; `backends/mlx/test/test_serialization_dedup.py` (asserts identical source/header are written once); `examples/models/gemma4_31b/quant/tests/test_gguf.py` and `examples/models/gemma4_31b/tests/test_mlx_pipeline.py`. - CI (`.github/workflows/mlx.yml`) discovers op tests recursively (`custom_kernel_ops/**/test/test_*.py`) so per-format subpackage tests run with no per-op CI edit. Run locally: ```bash # Build the op runner once (per CI): cmake --preset mlx-release -DEXECUTORCH_BUILD_TESTS=ON -DEXECUTORCH_MLX_ENABLE_SANITIZERS=OFF cmake --build cmake-out --target op_test_runner

charset=UTF-8 Content-Transfer-Encoding: 8bit ### Summary Introduce a backend-aware pass manager infrastructure for the Qualcomm backend. The monolithic QnnPassManager is refactored into a base class with overridable classmethods (`get_annotation_passes`, `get_export_passes`, `get_preprocess_passes`, etc.), enabling per-backend pass customization through inheritance. Three backend subclasses pass manager are added: - HTP / GPU — add `DecomposeReciprocal` (neither supports ElementWiseUnary with reciprocal operation) - LPAI — add `DecomposeReciprocal` + new `DecomposeHardsigmoid` pass, swap `FoldQDQ` for `LpaiFoldQDQ` (preserves I/O Q/DQ to avoid v6 accuracy drop) All call sites now use `get_qnn_pass_manager_cls(backend_type)()` to get the correct pass manager instance. ### Test plan - `python -m pytest backends/qualcomm/tests/test_passes.py::TestPasses::test_decompose_hardsigmoid_backend_aware -xvs` - `python -m pytest

Bonus small fix: Moves yolo import into test to avoid download at test collection time --------- Signed-off-by: Adrian Lundell --- backends/cortex_m/passes/BUCK | 4 +- backends/cortex_m/passes/__init__.py | 2 +- .../cortex_m/passes/aten_to_cortex_m_pass.py | 621 ++++++++++++++++++ .../passes/convert_to_cortex_m_pass.py | 572 ---------------- .../cortex_m/passes/cortex_m_pass_manager.py | 4 +- backends/cortex_m/test/models/test_yolo11.py | 12 +- backends/transforms/aten_to_dialect_pass.py | 22 +- .../test/test_aten_to_dialect_pass.py | 25 - 8 files changed, 634 insertions(+), 628 deletions(-) create mode 100644 backends/cortex_m/passes/aten_to_cortex_m_pass.py delete mode 100644 backends/cortex_m/passes/convert_to_cortex_m_pass.py diff --git a/backends/cortex_m/passes/BUCK b/backends/cortex_m/passes/BUCK index f1b7b9a201d..58a705ea3c6 100644 --- a/backends/cortex_m/passes/BUCK +++ b/backends/cortex_m/passes/BUCK @@ -29,8 +29,8 @@ fbcode_target(_kind = runtime.python_library, name="cortex_passes", srcs=[ "activation_fusion_pass.py", + "aten_to_cortex_m_pass.py", "clamp_hardswish_pass.py", - "convert_to_cortex_m_pass.py", "cortex_m_pass.py", "cortex_m_pass_manager.py", "decompose_hardswish_pass.py", @@ -45,8 +45,10 @@ fbcode_target(_kind = runtime.python_library, "//executorch/backends/cortex_m/ops:ops", "//executorch/backends/cortex_m/passes:passes_utils", "//executorch/backends/cortex_m/passes:replace_quant_nodes_pass", + "//executorch/backends/transforms:aten_to_dialect_pass", "//executorch/backends/transforms:remove_getitem_op", "//executorch/backends/transforms:replace_scalar_with_tensor", + "//executorch/backends/transforms:utils", "//executorch/exir:lib", "//executorch/exir:pass_base", "//executorch/exir:pass_manager", diff --git a/backends/cortex_m/passes/__init__.py b/backends/cortex_m/passes/__init__.py index c379461949f..cd1f2892de2 100644 --- a/backends/cortex_m/passes/__init__.py +++ b/backends/cortex_m/passes/__init__.py @@ -35,8 +35,8 @@ def _ensure_cortex_m_dependencies() -> None: from .cortex_m_pass import CortexMPass #

(#19974) ### Summary This PR updates the support for the `permute_copy` operator in the NXP backend to reflect the requirements of the new Neutron MLIR flow. In short, Neutron now supports all possible permutations without any restrictions. ### Test plan Unit tests provided. cc @robert-kalmar @JakeStevens @digantdesai @rascani --- backends/nxp/backend/edge_helper.py | 70 ++- .../nxp/backend/edge_program_converter.py | 9 +- backends/nxp/backend/ir/conversion_context.py | 9 +- .../ops_converters/getitem_converter.py | 15 +- .../ops_converters/permute_copy_converter.py | 114 +--- .../qdq_dequantize_converter.py | 41 +- .../ops_converters/qdq_quantize_converter.py | 10 +- .../prune_transpose_operators.py | 3 + .../nxp/backend/neutron_operator_support.py | 52 +- .../test_neutron_backend_executor.py | 164 +----- .../nxp/tests/generic_tests/test_quantizer.py | 2 +- .../test_avg_pool2d_converter.py | 6 +- .../node_converter/test_cat_converter.py | 15 +- .../node_converter/test_clone_converter.py | 5 +- .../test_max_pool_2d_converter.py | 4 +- .../node_converter/test_mean_dim_converter.py | 16 +- .../test_permute_copy_converter.py | 524 ++++++------------ .../test_view_copy_converter.py | 71 +-- .../tests/ir/edge_passes/test_edge_passes.py | 28 +- .../test_remove_io_quant_ops_pass.py | 3 + backends/nxp/tests/ops_aliases.py | 4 + 21 files changed, 366 insertions(+), 799 deletions(-) diff --git a/backends/nxp/backend/edge_helper.py b/backends/nxp/backend/edge_helper.py index 1ea86f589ac..c4c4e984f2d 100644 --- a/backends/nxp/backend/edge_helper.py +++ b/backends/nxp/backend/edge_helper.py @@ -8,27 +8,45 @@ import torch -from executorch.exir.dialects._ops import ops as exir_ops +from executorch.backends.nxp.tests.ops_aliases import ( + AddTensor, + Cat, + Clone, + CloneDimOrder, + DequantizePerChannel, + DequantizePerTensor, + MulTensor, + PermuteCopy, + QuantizePerChannel, + QuantizePerTensor, + SubTensor, + ViewCopy, +) from torch.fx import GraphModule, Node from torch.fx.node import Argument from torch.nn import Parameter QUANTIZE_OPERATORS = [ - exir_ops.edge.quantized_decomposed.quantize_per_channel.default, - exir_ops.edge.quantized_decomposed.quantize_per_tensor.default, + QuantizePerChannel, + QuantizePerTensor, + torch.ops.quantized_decomposed.quantize_per_tensor.default, + torch.ops.quantized_decomposed.quantize_per_channel.default, ] DEQUANTIZE_OPERATORS = [ - exir_ops.edge.quantized_decomposed.dequantize_per_channel.default, - exir_ops.edge.quantized_decomposed.dequantize_per_tensor.default, + DequantizePerChannel, + DequantizePerTensor, + torch.ops.quantized_decomposed.dequantize_per_tensor.default, + torch.ops.quantized_decomposed.dequantize_per_channel.default, ] # A set of operators which could possibly be no-ops in certain conditions.

They split the bias and input_offset×sum(weight) offset term between two inputs, in incompatible conventions: * MVE: reads `ctx.buf` as a precomputed kernel_sum that must already include `input_offset × sum(weight)` and the bias contribution. The `bias` argument is `(void)bias;` — ignored. * DSP / scalar: read the `bias` argument directly and fold the input_offset contribution at runtime. `ctx.buf` (kernel_sum) is `(void)kernel_sum;` — ignored. `ConvertToCortexMPass._get_linear_replacement` previously emitted only the MVE shape (kernel_sum populated, bias=None). On any non-MVE build the DSP/scalar path started the int32 accumulator at 0 instead of at `bias + input_offset × sum(weight)`, dropping both the bias and the offset contribution. The accumulator wound up much smaller than intended, requantization collapsed it to the output zero point, and every classifier with a deep, narrow tail produced essentially uniform near-zero outputs on non-MVE Cortex-M builds. Use the target-ISA plumbing added by the CortexMTargetConfig PR (#19470) to dispatch the right input shape at AOT time: on MVE targets emit kernel_sum with bias folded in (bias=None); on DSP and scalar targets emit the raw int32 bias directly (kernel_sum=None). The CMSIS-NN runtime then matches exactly what it expects. Update `quantized_linear_impl` in `operators.py` to mirror the same contract: dispatch off whichever of kernel_sum / bias is non-None. Threading happens automatically via `CortexMPassManager`'s signature injection of `target_config` into the pass's `__init__`. ### Test Plan Add `backends/cortex_m/test/misc/test_quantized_linear_small_magnitude.py` as a regression. A tiny `nn.Linear(512, 10)` on uniform[0, 0.002] input is the minimal reproducer for the small-magnitude regime where the missing offset terms dominate. The dialect test parametrizes over MVE/DSP/scalar target configs; the implementation test runs against whatever path the runner build matches. The DSP & Scalar tests will need #19520 for CI testing.

The kernel hardcoded `cmsis_ctx.buf = nullptr`, which worked on Cortex-M55 because the MVE variant ignores `ctx` entirely, but failed on any DSP-class core (e.g. Cortex-M7). The AoT scratch-buffer planning system introduced for conv/depthwise-conv/transpose-conv/bmm missed `quantized_avg_pool2d`; this extends it to cover that op. The `quantized_avg_pool2d` and `.out` schemas gain a `Tensor scratch` parameter. A new `cmsis_nn_avgpool_buffer_size` size function is registered, and avg_pool2d's lowering moves out of `QuantizedOpFusionPass` (which cannot create `exir.memory.alloc` nodes because it routes through `ExportPass.call_operator`) into `ConvertToCortexMPass`, alongside conv2d/bmm. The `count_include_pad` decomposition into an explicit `cortex_m::pad` node carries over to the new location. The kernel reads `scratch.nbytes()` and `scratch.mutable_data_ptr()` to wire `cmsis_nn_context`, with a `CORTEX_M_ENABLE_RUNTIME_CHECKS`-guarded assertion that the AoT and runtime buffer sizes agree — matching the conv2d pattern. The Python `_NHWC_DIM_ORDER` / `to_physical_order` helper that both passes need moves into `passes_utils.py` to avoid duplication. ### Test plan ``` examples/arm/run.sh --model_name=mv2 --target=cortex-m7 --bundleio ``` A new dialect test exercises the `ceil_mode=True` fallback so that future refactors do not silently change which path it takes.

Fix: Add a small thread-local handshake to the CUDA backend's stream layer in `backends/aoti/slim/cuda/guard`: `CallerStreamGuard`, an RAII scope that records (for the calling thread) the CUDA stream the backend should run on and restores the previous choice when it goes out of scope, and `getCallerStream()`, which returns that stream or nothing if no guard is active. The CUDA/AOTI backend now consults it: when a caller stream is set, `execute()` runs the kernels and the input and output copies on that stream; when none is set, it uses its own stream exactly as before, so existing behavior is unchanged. CUDA graph capture and replay is refused while a caller stream is set, because a captured graph is bound to its own stream. The handshake lives next to the existing stream registry and device guards in the same `guard` unit, so the delegate uses it without taking on a new dependency.

The handshake is a process-wide thread-local: the caller records the stream it wants, and each backend reads it. That only works if there is exactly one copy of the thread-local in the process. If the library were static and linked into two shared objects (for example the CUDA backend and a TensorRT delegate, each whole-archived for backend registration), each shared object would get its own copy, so the caller would write one and the backend would read the other and silently ignore the caller's stream. Building `extension_cuda` as SHARED gives one definition that every consumer references. It must be linked PUBLIC and never whole-archived. The two public functions are exported through a visibility macro (`extension/cuda/export.h`, mirroring `backends/aoti/export.h`) while the thread-local stays internal to the library. The C++ API is used directly: `getCallerStream()` returns `std::optional`, a trivially copyable pointer and bool that does not depend on the libstdc++ CXX11 ABI, so no C ABI is needed. The header is installed so an external project (such as a TensorRT delegate) can include it.

Enable VGF in pybind build if directed by env var. - Use VGF pybind in the wheel builds, based on package availability. ### Summary This adds VGF runtime delegate to end pip installs, and gives the option for ./install_executorch.sh to include it for developer side. This tidies up vgf with runtime installation further to the following: 1. developer flows: ./examples/arm/setup.sh --enable-mlsdk-deps; export EXECUTORCH_PYBIND_ENABLE_VGF=ON; ./install_executorch.sh --editable --optional-dependency vgf 3. wheel builds: # will invoke .ci/scripts/wheel/pre_build_script.sh which installs the build dependency # suitable platforms have EXECUTORCH_PYBIND_ENABLE_VGF=ON set 4. end users: pip install executorch[vgf] # published wheels contain runtime delegate on supported platforms cc @digantdesai @freddan80 @per @zingo @oscarandersson8218 @mansnils @Sebastian-Larsson @rascani --------- Signed-off-by: Rob Elliott --- .ci/scripts/wheel/pre_build_script.sh | 14 ++++++++++++++ CMakeLists.txt | 4 ++++ backends/arm/CMakeLists.txt | 3 +++ backends/arm/requirements-arm-vgf-runtime.txt | 8 ++++++++ backends/arm/requirements-arm-vgf.txt | 1 - backends/arm/scripts/setup-mlsdk-from-source.sh | 2 +- backends/arm/test/misc/test_vgf_check_env.py | 16 ++++++++++++++++ backends/arm/vgf/check_env.py | 12 +++++++----- examples/arm/setup.sh | 10 ++++++++-- tools/cmake/preset/pybind.cmake | 15 +++++++++++++++ 10 files changed, 76 insertions(+), 9 deletions(-) create mode 100644 backends/arm/requirements-arm-vgf-runtime.txt diff --git a/.ci/scripts/wheel/pre_build_script.sh b/.ci/scripts/wheel/pre_build_script.sh index 365398d27a4..5ad57f3c710 100755 --- a/.ci/scripts/wheel/pre_build_script.sh +++ b/.ci/scripts/wheel/pre_build_script.sh @@ -2,6 +2,8 @@ # Copyright (c) Meta Platforms, Inc. and affiliates. # All rights reserved. # +# Copyright 2026 Arm Limited and/or its affiliates. +# # This source code is licensed under the BSD-style license found in the # LICENSE file in the root directory of this source tree. @@ -57,6 +59,18 @@ fi "${GITHUB_WORKSPACE}/${REPOSITORY}/install_requirements.sh" --example +# Enable VGF in pybind wheel builds when the platform-specific build input is +# available from pip. +if [[ "$UNAME_S" == "Linux" || "$UNAME_S" == "Darwin" ]]; then + if python3 -m pip install -r \ + "${GITHUB_WORKSPACE}/${REPOSITORY}/backends/arm/requirements-arm-vgf-runtime.txt"; then + export EXECUTORCH_PYBIND_ENABLE_VGF=ON + echo "EXECUTORCH_PYBIND_ENABLE_VGF=ON" >> "${GITHUB_ENV}" + else + echo "VGF build dependency unavailable on this platform; building without VGF" + fi +fi + # Download Qualcomm QNN SDK on Linux x86_64 so the wheel build can include the # QNN backend.

script above, 1 wikitext sample is used to evaluate all 3 phases. However, there are cases where a user may want to use one sample for quantization calibration and multiple samples for perplexity evaluation. In this case, the process should be split into two runs. In the 1st run, the model is compiled using one sample. In the 2nd run, the user can provide a different configuration for QNN device execution.

Since it is using its own tool chain, some of the C/C++ files or functions are not accessible. For example, in this PR, `extension/data_loader/mman.h` uses some MACRO that is not no Hexagon toolchain. Due to this reason, mainline often breaks direct-build when someone included functions that's not supported by Hexagon tool chain. To prevent this to happen, this PR added: 1. direct-build to CI test to ensure changes doesn't break direct build 2. Ensure the direct build artifact size is smaller than 200kb ### Test plan Passing `test-qnn-direct-build-linux` under `pull.yml` --- .ci/scripts/build-qnn-direct-sdk.sh | 33 +++++++++ .github/workflows/pull.yml | 19 +++++ CMakeLists.txt | 23 +++--- backends/qualcomm/scripts/build.sh | 1 + backends/qualcomm/scripts/build_utils.sh | 16 ++-- backends/qualcomm/scripts/install_qnn_sdk.sh | 77 ++++++++++++++++++++ backends/qualcomm/scripts/qnn_config.sh | 8 ++ extension/data_loader/mman.h | 7 ++ 8 files changed, 167 insertions(+), 17 deletions(-) create mode 100755 .ci/scripts/build-qnn-direct-sdk.sh diff --git a/.ci/scripts/build-qnn-direct-sdk.sh b/.ci/scripts/build-qnn-direct-sdk.sh new file mode 100755 index 00000000000..4eccd0115f4 --- /dev/null +++ b/.ci/scripts/build-qnn-direct-sdk.sh @@ -0,0 +1,33 @@ +#!/bin/bash +# Copyright (c) Qualcomm Innovation Center, Inc. +# All rights reserved +# +# This source code is licensed under the BSD-style license found in the +# LICENSE file in the root directory of this source tree. + +set -eux + +source "$(dirname "${BASH_SOURCE[0]}")/../../backends/qualcomm/scripts/install_qnn_sdk.sh" + +setup_android_ndk +install_qnn +install_hexagon_sdk + +bash backends/qualcomm/scripts/build.sh \ + --build_direct_mode 3 --soc_model SM8750 \ + --skip_x86_64 --skip_linux_android \ + --release + +ARTIFACT="build-direct/backends/qualcomm/libqnn_executorch_backend.so" +if [ ! -f "${ARTIFACT}" ]; then + echo "ERROR: direct-mode build did not produce ${ARTIFACT}" >&2 + exit 1 +fi + +MAX_SIZE_BYTES=$((200 * 1024)) +ARTIFACT_SIZE=$(stat -c%s "${ARTIFACT}") +if [ "${ARTIFACT_SIZE}" -gt "${MAX_SIZE_BYTES}" ]; then + echo "ERROR: ${ARTIFACT} is ${ARTIFACT_SIZE} bytes, exceeds ${MAX_SIZE_BYTES}-byte (200 KiB) limit" >&2 + exit 1 +fi +echo "PASSED: direct-mode build produced ${ARTIFACT} (${ARTIFACT_SIZE} bytes, under ${MAX_SIZE_BYTES}-byte limit)" diff --git a/.github/workflows/pull.yml b/.github/workflows/pull.yml index 3ead9e6a49c..0ecab2c11b5 100644 --- a/.github/workflows/pull.yml +++ b/.github/workflows/pull.yml @@ -948,6 +948,25 @@ jobs: PYTHON_EXECUTABLE=python bash .ci/scripts/build-qnn-sdk.sh PYTHON_EXECUTABLE=python bash .ci/scripts/test_model.sh ${{ matrix.model }} "cmake" "qnn" + test-qnn-direct-build-linux: + name: test-qnn-direct-build-linux + uses: pytorch/test-infra/.github/workflows/linux_job_v2.yml@main + permissions: + id-token: write + contents: read + with: + runner: linux.2xlarge + docker-image: ci-image:executorch-ubuntu-22.04-qnn-sdk + submodules: 'recursive' + ref: ${{ github.event_name == 'pull_request' && github.event.pull_request.head.sha || github.sha }} + timeout: 30 + script: | + # The generic Linux job chooses to use base env, not the one setup by the image + CONDA_ENV=$(conda env list --json | jq -r ".envs | .[-1]") + conda activate "${CONDA_ENV}" + PYTHON_EXECUTABLE=python bash .ci/scripts/setup-linux.sh --build-tool cmake + PYTHON_EXECUTABLE=python bash .ci/scripts/build-qnn-direct-sdk.sh + test-qnn-testsuite-linux: name: test-qnn-testsuite-linux permissions: diff --git a/CMakeLists.txt b/CMakeLists.txt index 51b0b6107cb..abd032e3e30 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -49,17 +49,6 @@ cmake_minimum_required(VERSION 3.24) set(EXECUTORCH_ROOT ${CMAKE_CURRENT_SOURCE_DIR}) -# Hexagon toolchain with release build complains about code in third party -# libraries. -if("${CMAKE_SYSTEM_PROCESSOR}" MATCHES "Hexagon" AND "${CMAKE_BUILD_TYPE}" - STREQUAL "Release" -) - add_compile_options( - -Wno-error=format -Wno-error=implicit-int-conversion - -Wno-error=unused-variable -Wno-error=unused-function - ) -endif() - # --- ExecuTorch Version --- # Parse version from version.txt (single source of truth) file(READ "${EXECUTORCH_ROOT}/version.txt" ET_VERSION_STRING) @@ -90,6 +79,18 @@ project(executorch VERSION "${ET_VERSION_MAJOR}.${ET_VERSION_MINOR}.${ET_VERSION_PATCH}" ) +# Hexagon toolchain with release build complains about code in third party +# libraries.

The trunk job opts in to `["cortex-m55", "cortex-m7"]`; the nightly job (and any future caller that doesn't pass `targets`) falls back to the M55-only default and keeps its current shape. Cortex-M7 is the first non-MVE variant to enter CI. It exercises the DSP-class CMSIS-NN kernel paths (selected via `__ARM_FEATURE_DSP`), covering the build plumbing that threads `-mcpu=cortex-m7` through to both the runner and the core libraries. `pull.yml`'s `test-mcu-cortex-m-backend` is intentionally left at M55-only — per-PR coverage is deferred until the trunk M7 leg demonstrates stability over a few cycles. ### Test plan CI Authored with Claude. --- .ci/scripts/test_cortex_m_e2e.sh | 5 +++-- .github/workflows/_test_cortex_m_e2e.yml | 10 ++++++++-- .github/workflows/trunk.yml | 1 + 3 files changed, 12 insertions(+), 4 deletions(-) diff --git a/.ci/scripts/test_cortex_m_e2e.sh b/.ci/scripts/test_cortex_m_e2e.sh index ac6e6d46550..9586dbb51c1 100755 --- a/.ci/scripts/test_cortex_m_e2e.sh +++ b/.ci/scripts/test_cortex_m_e2e.sh @@ -14,13 +14,14 @@ set -eu MODEL=$1 +TARGET=${2:-cortex-m55} script_dir=$(realpath "$(dirname "${BASH_SOURCE[0]}")") et_root_dir=$(realpath "${script_dir}/../..") -# Quantization is the default for the cortex-m55 target; run.sh's +# Quantization is the default for cortex-m targets; run.sh's # arg parser only recognizes --no_quantize, so we omit any explicit flag. export ARM_FVP_INSTALL_I_AGREE_TO_THE_CONTAINED_EULA=True bash "${et_root_dir}/examples/arm/run.sh" \ --model_name="${MODEL}" \ - --target=cortex-m55 \ + --target="${TARGET}" \ --bundleio diff --git a/.github/workflows/_test_cortex_m_e2e.yml b/.github/workflows/_test_cortex_m_e2e.yml index 6b0398ca998..3feffad571e 100644 --- a/.github/workflows/_test_cortex_m_e2e.yml +++ b/.github/workflows/_test_cortex_m_e2e.yml @@ -11,6 +11,11 @@ on: description: 'JSON array of model names to run on the Corstone-300 FVP, e.g. ["mv2", "mv3"]' required: true type: string + targets: + description: 'JSON array of cortex-m target CPUs to build the runner for, e.g. ["cortex-m55", "cortex-m7"]' + required: false + type: string + default: '["cortex-m55"]' timeout: description: 'Per-matrix-entry timeout in minutes' required: false @@ -23,9 +28,10 @@ jobs: strategy: matrix: model: ${{ fromJSON(inputs.models) }} + target: ${{ fromJSON(inputs.targets) }} fail-fast: false with: - job-name: ${{ matrix.model }} + job-name: ${{ matrix.model }}-${{ matrix.target }} runner: linux.2xlarge.memory docker-image: ci-image:executorch-ubuntu-22.04-arm-sdk submodules: 'recursive' @@ -44,4 +50,4 @@ jobs: source examples/arm/arm-scratch/setup_path.sh # Export and run model on FVP (run.sh internally builds the test runner). - bash .ci/scripts/test_cortex_m_e2e.sh ${{ matrix.model }} + bash .ci/scripts/test_cortex_m_e2e.sh "${{ matrix.model }}" "${{ matrix.target }}" diff --git a/.github/workflows/trunk.yml b/.github/workflows/trunk.yml index 03732fa35e2..2f97b49ae9d 100644 --- a/.github/workflows/trunk.yml +++ b/.github/workflows/trunk.yml @@ -1075,3 +1075,4 @@ jobs: uses: ./.github/workflows/_test_cortex_m_e2e.yml with: models: '["mv2", "mv3"]' + targets: '["cortex-m55", "cortex-m7"]' From 8e10687838d66801bc0e2e09e698ddd92648700e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Per=20=C3=85strand?= Date: Fri, 27 Mar 2026 12:14:43 +0100 Subject: [PATCH 251/317] Arm backend: Bump to 2026.05 release of tosa-tools MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bump the release to 2026.05 and enable the compatibility flag for the serialization to make current and older versions of model-converter being able to deserialize the resulting flatbuffer file.

Generalize the guard to all GCC variants so gcc14, gcc15, and future additions get the same protection. Images that set SKIP_PYTORCH (gcc9-nopytorch, cuda-windows) are unaffected because the existing SKIP_PYTORCH guard excludes them.

Keep those parser suppressions local to prim_ops instead of adding inline suppressions throughout the file.

The trunk job opts in to `["cortex-m55", "cortex-m0plus"]`; the nightly job (and any future caller that doesn't pass `targets`) falls back to the M55-only default and keeps its current shape. Cortex-M0+ is the first scalar-class (Armv6-M) variant to enter CI. It exercises the pure-C CMSIS-NN kernel path (`__ARM_FEATURE_DSP` and `__ARM_FEATURE_MVE` both undefined), covering the M0+ enablement patches that fix the Armv6-M HardFault handler and the `ARMCM0plus` directory-case mismatch in the Cortex DFP.

From 45190368d8d54247833f9dd7fbf427730c4e3ad1 Mon Sep 17 00:00:00 2001 From: Siddartha Pothapragada Date: Wed, 10 Jun 2026 13:53:31 -0400 Subject: [PATCH 259/317] Route Module.loadMethod through makeExecutorchException for native log enrichment (#20191) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Summary: `Module.loadMethod` directly constructs `ExecutorchRuntimeException`, bypassing the `makeExecutorchException` factory that enriches error details with the native log tail (added in D107196396). As a result, the high-volume SceneX XNNPACK 0x12 `loadMethod` failures (`[ExecuTorch Error 0x12] Invalid argument: Failed to load method: forward`) never capture native diagnostic context — `nativeLog=` never appears in Scuba/QPL data. Route the throw through the factory so these failures get the native log tail for triage. The change is applied to both the `xplat` and `fbcode` copies of `Module.kt` to keep them in sync, mirroring how D107196396 edited both copies of `ExecutorchRuntimeException.kt`. For error code 0x12 (`INVALID_ARGUMENT`), `makeExecutorchException` returns `ExecutorchInvalidArgumentException`, a subclass of `ExecutorchRuntimeException` that carries the same `errorCode`, so existing `catch (ExecutorchRuntimeException)` and `getErrorCode()` consumers are unaffected. The enrichment runs only on the failure path (not per-call) and uses the static `readLogBufferStatic` JNI read, which takes a separate native mutex, so it does not re-enter the `mLock` held by `loadMethod`. The change is additive: when no native logs are available the message is byte-identical to today's. This was authored with assistance from Claude.

This avoids stalling the whole queue and only waits for the work submitted by the backend. Create the execution fence once during VGF setup and reuse it across execute_vgf() calls by resetting it before each submission.

charset=UTF-8 Content-Transfer-Encoding: 8bit Summary: Adds a standalone microbenchmark for the ImageProcessor reuse APIs and a companion script to diff two runs, so kernel/pipeline changes (e.g. the NEON deinterleave switch) can be measured reproducibly. New directory xplat/executorch/extension/image/benchmark/: * image_processor_benchmark.cpp (cxx_binary) — times process_into (BGRA/RGBA) and process_yuv_into (NV12/NV21) over a sweep of common input sizes × target sizes. Per cell it runs variants covering execution path (CPU / GPU / size-default), resize mode (stretch / letterbox), orientation (upright + 90°), cropped ROI, and the allocating process() vs process_into(). Each row reports mean/median/p95/stddev over 100 iters (10 warmup) on a synthetic gradient input; a row that fails is reported as ERROR rather than timed. * Flags (all optional): --format=bgra|rgba|nv12|nv21, --unit=cpu|gpu|default (both default to all), --out=PATH (writes a clean results table; the input-size sweep and rotation always run). Output is grouped under === API-section banners with a column legend, and --- per-cell separators. * compare_benchmarks.py (python_binary, stdlib-only) — matches rows by (API section, input→target cell, variant) and prints per-row base / new speedup plus a summary bucketed by execution path (CPU / GPU / default). * README.md — usage, the build-mode caveat, and the capture→compare workflow. * BUCK / TARGETS / targets.bzl — build defs. Note: benchmark only with an optimized build (-c cxx.extra_cxxflags=-Os); the default buck2 run is -O0 and unrepresentative.
