Subject: [PATCH 002/423] Support dim_order in CoreML (#12985)

Add support for dim_order op in CoreML.

Currently, the dim_order op is skipped. This occasionally leads to
lowering / runtime errors, so often you have a better experience by
setting _skip_dim_order=True.

This will fix the CI failure in trunk / test-models-macos-coreml
(emformer_transcribe) / macos-job

Subject: [PATCH 004/423] [ET-VK] Migrate off of xnnpack_quantizer_utils
 (#12998)

# Context

Eventually as the vulkan_quantizer file expands, we will need to migrate into a custom utils file and stop depending on the xnnpack_quantizer_utils. We migrate only the minimal amount of functions necessary to ensure the vulkan_quantizer works.

# Changes

We create a new file `vulkan_quantizer_utils.py` and migrate off of `xnnpack_quantizer_utils.py` in `vulkan_quantizer`. There are no specific modifications necessary to work separate from xnnpack utils except bits_to_range to allow not needing to specify the ranges everytime.

 /*
- * QUANTIZATION PARAMETER COMPUTATION SHADER (BUFFER STORAGE)
- *
- * This shader computes quantization parameters (scale and zero_point) for converting
- * floating-point tensors to n-bit integer representations while preserving the
- * original data range as much as possible.
- *
- * ALGORITHM:
- * 1. Find global min/max values across tensor elements using parallel reduction
- * 2. Use tree reduction with shared memory for efficient min/max computation
- * 3. Calculate scale = (max - min) / (quant_max - quant_min)
- * 4. Calculate zero_point to map floating-point zero to integer value
- *
- * WORKGROUP CONFIGURATION:
- * - Per-Tensor Mode:
- *   - Global WG Size: {1, 1, 1} (single workgroup processes entire tensor)
- *   - Local WG Size: {64, 1, 1} (matches NWORKERS for shared memory)
- * - Per-Token Mode:
- *   - Global WG Size: {num_tokens, 1, 1} (one workgroup per token)
- *   - Local WG Size: {64, 1, 1} (matches NWORKERS for shared memory)
- *
- * SUPPORTED CONFIGURATIONS:
- * - Buffer Storage: Uses simple linear indexing through buffer elements
- * - No axis mapping or packing considerations - processes elements sequentially
- * - Works with any tensor layout since it accesses buffer data linearly
- *
- * TREE REDUCTION VISUALIZATION FOR MIN/MAX FINDING:
- * For 8 threads processing elements [10, 1, 8, 1, 0, 2, 3, 5]:
- *
- * Initial shared_min/shared_max arrays populated by each thread:
- * shared_min:  | 10 | 1 | 8 | 1 | 0 | 2 | 3 | 5 |
- * shared_max:  | 10 | 1 | 8 | 1 | 0 | 2 | 3 | 5 |
- * Thread:      |  0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |

+  Quantization Parameter Computation Shader (Buffer Storage)
+    This shader computes quantization parameters (scale and zero_point) for converting
+    floating-point tensors to n-bit integer representations while preserving the
+    original data range as much as possible. The computed parameters enable efficient
+    quantization by mapping the continuous floating-point range to discrete integer values.
+
+  Important Considerations:
+    (+) The input tensor is assumed to be WIDTH_PACKED (i.e., contiguous in the last dimension)
+
+  Workgroup Configuration:
+  - choose_qparams_per_tensor
+      This mode computes a single set of quantization parameters for the entire tensor.
+      Uses parallel reduction across all threads to find global min/max values.
+
+    (*) global_wg_size: {1, 1, 1} (single workgroup processes entire tensor)
+    (*) local_wg_size: {64, 1, 1} (matches NWORKERS for shared memory)
+
+  - choose_qparams_per_token
+      This mode computes separate quantization parameters for each token in the tensor.
+      Each workgroup processes one token independently to find token-specific min/max.
+
+    (*) global_wg_size: {num_tokens, 1, 1} (one workgroup per token)
+    (*) local_wg_size: {1, 1, 1} (single thread per token)
+
+  - choose_qparams_block_wise
+      This mode computes quantization parameters for each block of elements, allowing
+      fine-grained control over quantization granularity within the tensor. Each block
+      is processed independently to find its own min/max values and compute corresponding
+      scale and zero_point parameters.
+
+    (*) global_wg_size: {nBlocks, 1u, 1u} (one workgroup per block)
+    (*) local_wg_size: {1, 1, 1} (single thread per block)
+
+    Block-wise quantization supports multiple mapping types for scale/zero_point calculation:
+
+    - mapping_type = 0 (ASYMMETRIC):
+        Uses asymmetric quantization where the full floating-point range [min, max] is
+        mapped to the quantized range [quant_min, quant_max]. This preserves the original
+        data distribution but may not center zero optimally.
+
+        Calculation:
+        scale = (max - min) / (quant_max - quant_min)
+        zero_point = quant_min - round(min / scale)
+
+        Example: For range [-3.5, 10.2] mapping to int4 [-8, 7]:
+        scale = (10.2 - (-3.5)) / (7 - (-8)) = 13.7 / 15 = 0.913
+        zero_point = -8 - round(-3.5 / 0.913) = -8 - (-4) = -4
+
+    - mapping_type = 1 (SYMMETRIC):
+        Uses symmetric quantization where the range is centered around zero. The scale
+        is computed based on the maximum absolute value, ensuring zero is exactly
+        representable in the quantized domain.
+
+        Calculation:
+        max_abs = max(abs(min), abs(max))
+        scale = max_abs / ((quant_max - quant_min) / 2)
+        zero_point = (quant_max + quant_min + 1) / 2  // midpoint
+
+        Example: For range [-3.5, 10.2] mapping to int4 [-8, 7]:
+        max_abs = max(3.5, 10.2) = 10.2
+        scale = 10.2 / ((7 - (-8)) / 2) = 10.2 / 7.5 = 1.36
+        zero_point = (-8 + 7 + 1) / 2 = 0
+
+    - mapping_type = 2 (SYMMETRIC_NO_CLIPPING_ERR):
+        A variant of symmetric quantization that minimizes clipping errors by computing
+        separate scales for positive and negative ranges, then using the maximum. This
+        reduces quantization error on the dominant range while ensuring no values are
+        clipped.
+
+        Calculation:
+        smin = abs(min) / abs(quant_min)  // scale for negative range
+        smax = max / quant_max            // scale for positive range
+        scale = max(smin, smax)           // use larger scale to avoid clipping
+        zero_point = (quant_max + quant_min + 1) / 2  // midpoint
+
+        Example: For range [-3.5, 10.2] mapping to int4 [-8, 7]:
+        smin = 3.5 / 8 = 0.4375
+        smax = 10.2 / 7 = 1.457
+        scale = max(0.4375, 1.457) = 1.457  // use smax to avoid clipping positives
+        zero_point = (-8 + 7 + 1) / 2 = 0
+
+  Tree Reduction Algorithm for Min/Max Finding:
+    The shader uses a parallel tree reduction algorithm to efficiently find minimum and
+    maximum values across multiple threads. This approach reduces the number of memory
+    accesses and synchronization points compared to sequential scanning.
+
+    Example with 8 threads processing values [10, 1, 8, 1, 0, 2, 3, 5]:
+
+    Step 1 - Initial Population:
+    Each thread loads its assigned value into shared memory arrays.
+    shared_min:  | 10 | 1 | 8 | 1 | 0 | 2 | 3 | 5 |
+    shared_max:  | 10 | 1 | 8 | 1 | 0 | 2 | 3 | 5 |
+    Thread ID:   |  0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
+
+    Step 2 - Stride 1 (Compare Adjacent Pairs):
+    Threads 0,2,4,6 compare with threads 1,3,5,7 respectively.
+    shared_min:  |  1 |   | 1 |   | 0 |   | 3 |   |  (min(10,1), min(8,1), min(0,2), min(3,5))
+    shared_max:  | 10 |   | 8 |   | 2 |   | 5 |   |  (max(10,1), max(8,1), max(0,2), max(3,5))
+    Active:      |  0 |   | 2 |   | 4 |   | 6 |   |
+
+    Step 3 - Stride 2 (Compare Pairs of Pairs):
+    Threads 0,4 compare with threads 2,6 respectively.
+    shared_min:  |  1 |   |   |   | 0 |   |   |   |  (min(1,1), min(0,3))
+    shared_max:  | 10 |   |   |   | 5 |   |   |   |  (max(10,8), max(2,5))
+    Active:      |  0 |   |   |   | 4 |   |   |   |
+
+    Step 4 - Stride 4 (Final Comparison):
+    Thread 0 compares with thread 4 to get final result.
+    shared_min:  |  0 |   |   |   |   |   |   |   |  (min(1,0) = 0)
+    shared_max:  | 10 |   |   |   |   |   |   |   |  (max(10,5) = 10)
+    Active:      |  0 |   |   |   |   |   |   |   |
+
+    Final Result: global_min = 0, global_max = 10 (stored in shared_min[0], shared_max[0])
+
+    The tree reduction completes in log_2(N) steps where N is the number of threads,
+    providing O(log N) time complexity instead of O(N) for sequential reduction.
+
+  Quantization Parameter Calculation:
+    Once min/max values are determined, the shader computes:
+    - scale = (max - min) / (quant_max - quant_min)
+    - zero_point = quantization offset to map floating-point zero to integer range
+
+  Mode-Specific Behavior:
+  - Per-Tensor: Single workgroup with strided access across entire tensor
+  - Per-Token: Multiple workgroups, each processing one token independently
+  - Block-Wise: Each thread processes assigned blocks using nested loops over block dimensions

+  Quantization Parameter Computation Shader (Buffer Storage)
+    This shader computes quantization parameters (scale and zero_point) for converting
+    floating-point tensors to n-bit integer representations while preserving the
+    original data range as much as possible. The computed parameters enable efficient
+    quantization by mapping the continuous floating-point range to discrete integer values.
+
+  Important Considerations:
+    (+) The input tensor is assumed to be WIDTH_PACKED (i.e., contiguous in the last dimension)
+
+  Workgroup Configuration:
+  - choose_qparams_per_tensor
+      This mode computes a single set of quantization parameters for the entire tensor.
+      Uses parallel reduction across all threads to find global min/max values.
+
+    (*) global_wg_size: default
+    (*) local_wg_size: default
+
+  - choose_qparams_per_token
+      This mode computes separate quantization parameters for each token in the tensor.
+      Each workgroup processes one token independently to find token-specific min/max.
+
+    (*) global_wg_size: default
+    (*) local_wg_size: {1, 1, 1}
+
+  - choose_qparams_block_wise
+      This mode computes quantization parameters for each block of elements, allowing
+      fine-grained control over quantization granularity within the tensor. Each block
+      is processed independently to find its own min/max values and compute corresponding
+      scale and zero_point parameters.
+
+      NOTE: This mode currently only supports buffer storage for the output.
+
+    (*) global_wg_size: {nBlocks, 1u, 1u} (one workgroup per block)
+    (*) local_wg_size: {1, 1, 1} (single thread per block)
+
+  Tree Reduction Algorithm for Min/Max Finding:
+    The shader uses a parallel tree reduction algorithm to efficiently find minimum and
+    maximum values across multiple threads. This approach reduces the number of memory
+    accesses and synchronization points compared to sequential scanning.
+
+    Example with 8 threads processing values [10, 1, 8, 1, 0, 2, 3, 5]:
+
+    Step 1 - Initial Population:
+    Each thread loads its assigned value into shared memory arrays.
+    shared_min:  | 10 | 1 | 8 | 1 | 0 | 2 | 3 | 5 |
+    shared_max:  | 10 | 1 | 8 | 1 | 0 | 2 | 3 | 5 |
+    Thread ID:   |  0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
+
+    Step 2 - Stride 1 (Compare Adjacent Pairs):
+    Threads 0,2,4,6 compare with threads 1,3,5,7 respectively.
+    shared_min:  |  1 |   | 1 |   | 0 |   | 3 |   |  (min(10,1), min(8,1), min(0,2), min(3,5))
+    shared_max:  | 10 |   | 8 |   | 2 |   | 5 |   |  (max(10,1), max(8,1), max(0,2), max(3,5))
+    Active:      |  0 |   | 2 |   | 4 |   | 6 |   |
+
+    Step 3 - Stride 2 (Compare Pairs of Pairs):
+    Threads 0,4 compare with threads 2,6 respectively.
+    shared_min:  |  1 |   |   |   | 0 |   |   |   |  (min(1,1), min(0,3))
+    shared_max:  | 10 |   |   |   | 5 |   |   |   |  (max(10,8), max(2,5))
+    Active:      |  0 |   |   |   | 4 |   |   |   |
+
+    Step 4 - Stride 4 (Final Comparison):
+    Thread 0 compares with thread 4 to get final result.
+    shared_min:  |  0 |   |   |   |   |   |   |   |  (min(1,0) = 0)
+    shared_max:  | 10 |   |   |   |   |   |   |   |  (max(10,5) = 10)
+    Active:      |  0 |   |   |   |   |   |   |   |
+
+    Final Result: global_min = 0, global_max = 10 (stored in shared_min[0], shared_max[0])
+
+    The tree reduction completes in log_2(N) steps where N is the number of threads,
+    providing O(log N) time complexity instead of O(N) for sequential reduction.
+
+  Quantization Parameter Calculation:
+    Once min/max values are determined, the shader computes:
+    - scale = (max - min) / (quant_max - quant_min)
+    - zero_point = quantization offset to map floating-point zero to integer range
+
+  Mode-Specific Behavior:
+  - Per-Tensor: Single workgroup with strided access across entire tensor
+  - Per-Token: Multiple workgroups, each processing one token independently

+  Quantization Shader (Buffer Storage)
+    This shader converts floating-point tensor values to n-bit integer representations
+    using pre-computed quantization parameters (scale and zero_point). The quantization
+    maps floating-point values to a discrete integer range while preserving the original
+    data distribution as much as possible.
+
+  Important Considerations:
+    (+) All input tensors are assumed to be WIDTH_PACKED (i.e., contiguous in the last dimension)
+    (+) The axis map layout is assumed to be a standard layout for scales and zero_points
+    (++) The scale and zero_point tensors must be implemented as buffers
+
+  Workgroup Configuration:
+  - quantize_per_tensor
+      This mode applies uniform quantization across the entire tensor using a single scale
+      and zero_point value.
+
+    (*) global_wg_size: default
+    (*) local_wg_size: default
+
+  - quantize_per_token
+      This mode applies quantization individually to each token (or element) in the input,
+      using separate scale and zero_point values for each token. For instance if we have
+      a tensor of shape [B, S, H] then we have B*S tokens (and s+zp pairs) of H elements each.
+
+    (*) global_wg_size: default
+    (*) local_wg_size: default
+
+  - quantize_per_channel
+      This mode applies quantization separately to each channel of the input tensor, using
+      distinct scale and zero_point values for each channel. For example, if the tensor shape
+      is [B, C, H, W] and axis = 1, quantization parameters are computed per channel C, allowing
+      each channel to be quantized independently.
+
+    (*) global_wg_size: default
+    (*) local_wg_size: default
+
+  - quantize_block_wise
+      This mode applies quantization in blocks or groups of elements, allowing different scale
+      and zero_point values for each block. It is equivalent to quantize_affine, where quantization
+      parameters are affine transformations applied per block. For example, if the tensor shape
+      is [6, 9, 4] and blockSize = [3, 3, 2], then we have 12 blocks each with 18 elements.
+
+    (*) global_wg_size: default
+    (*) local_wg_size: default

Subject: [PATCH 009/423] Add torchao kernels to xcframework (#10963)

### Summary

In accordance with the following
[ticket](https://github.com/pytorch/executorch/issues/10694), we want to
enable building the torchao kernel through the main ExecuTorch
CMakeLists.txt. This PR should cover all the necessary steps required to
build low-bit kernels on the iOS app.

#### List of changes
- Provide an optional flag `EXECUTORCH_BUILD_KERNELS_TORCHAO` that
enables building torchao through the CMakeLists.txt.
- Update the apple framework script to include the torchao build.
- Updated the apple framework defaults to include torchao.

### Test plan
- Code has been successfully tested on the iPhone 16 simulator

+    This class is responsible for representing and managing the set of valid tensor
+    representations that may be used for all input and output tensors of an operator.
+    It is also responsible for maintaining synchronization rules between tensors
+    participating in the computation.
+
+    Currently, three synchronization rules exist:
+    1. All input tensors must use the same representation (e.g. binary ops)
+    2. The "primary" input and output tensors must use the same representation
+       (e.g. group norm; the output is a tuple of out, mean, rstd; out must be the same
+       representation as the first input x, but mean and rstd may use different
+       representations as out)
+    3. All output tensors must use the same representation (e.g. choose qparams)
+
+    Note that "primary" input and output tensor refers to the first non-weight input
+    tensor and the first output tensor. Note that Some operators (such as arange) do not
+    have any tensor inputs.
+
+    Currently, the above three synchronization rules are sufficient to describe the
+    representation requirements of all ET-VK operators.
+
+    This class also provides utilities to constrain the repsets; when applying the
+    constraints, the synchronization rules will be maintained.

+  #
+  # Currently, the convention used by Vela and the Ethos-U driver is that the

+  # Region 1 for traffic of of the intermediate Read/Write buffers required for
+  # the computation Region 2 for traffic of of the cache in Dedicated_Sram
+  # memory mode(not applicable in Sram_Only or Shared_Sram)

+  # NOTE: The above convention is determined by the Vela compiler and the
+  # Ethos-U driver and can change in the future.
+  #

+  # model for Dedicated_Sram, the memory traffic for Region 0 should pass via

-# The REGIONCFG registers of the Ethos-U control whether the NPU

-# By default, the Ethos-U driver provides REGIONCFG configuration for Shared Sram memory mode.
-# For Sram_Only and Dedicated_Sram memory modes, we need to change the settings for optimal performance.
-#
-# Currently, the convention used by Vela and the Ethos-U driver is that the NPU uses:
-# Region 0 for traffic of the Read-Only data(weights & biases)
-# Region 1 for traffic of of the intermediate Read/Write buffers required for the computation
-# Region 2 for traffic of of the cache in Dedicated_Sram memory mode(not applicable in Sram_Only or Shared_Sram)
-#
-# NOTE: The above convention is determined by the Vela compiler and the Ethos-U driver and can change in the future.
-#
-# Common definitions:
-# For Ethos-U55/U65/U85, region configs are set as:
-#   0 or 1 = AXI0 (Ethos-U55 or Ethos-U65) or AXI_SRAM(Ethos-U85)
-#   2 or 3 = AXI1 (Ethos-U55 or Ethos-U65) or AXI_EXT(Ethos-U85)
-#
-# When we compile a model for Sram_Only, the memory traffic for Region 0 and Region 1 should pass via the SRAM(hence regioncfg = 1)
-# When we compile a model for Dedicated_Sram, the memory traffic for Region 0 should pass via the external memory(3),
-# the memory traffic of Region 1 should pass via the external memory(3) and the traffic for Region 2 should pass via the SRAM(0)

Subject: [PATCH 015/423] Arm backend: Eliminate one memory copy in executor
 runner (#12992)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prior to this patch, temporary tensors/buffers were used to hold the
input data which was then copied over to the actual input tensors for
running the inference. This patch removes this copying by instead
writing the input data directly to the input tensors.

Subject: [PATCH 017/423] Arm backend: support list-of-tensors args in
 FuseConstantArgsPass (#13037)

FuseConstantArgsPass is changed so that it no longer unpacks lists or
tuples in node.args and node.kwargs. Those sequences are now preserved
when the operator is invoked. That means ops like aten::cat, which
expect their first argument to be a `List[Tensor]`, still get exactly
that. Previously, the pass would flatten the list into separate tensor
arguments, leading to this runtime error:

[WARNING 2025-07-24 11:37:13,749 fuse_constant_ops_pass.py:133] Failed
to fuse constant op aten_cat_default due to exception: aten::cat()
Expected a value of type 'List[Tensor]' for argument 'tensors' but
instead found type 'Tensor'.

Subject: [PATCH 028/423] Do not use BNNS copy when dtypes differ in CoreML
 (#13018)

BNNS copy crashes the process when the dtypes differ
(https://github.com/pytorch/executorch/issues/11714).

With the example in this PR
(https://github.com/pytorch/executorch/issues/11714), we crash the
process on main. Here is the stack trace from LLDB:

Subject: [PATCH 038/423] Fix installation that causes torch conflict (#13074)

Looking into resolving this:
https://github.com/pytorch/pytorch/issues/159599

A package in requirements-examples.txt had a dependency on torchvision,
and we ended up installing stable release from standard pypi package.
And transitively we ended up installing stable torch and uninstalling
existing torch nightly.

We just need to swap the installation (first install domain libraries
and torch) and then necessary examples packages.

Test Plan:

`python ./install_requirements.sh --example`

Outputs

```
(executorch_test_9) mnachin@mnachin-mbp executorch % pip freeze | grep torch
pytorch_tokenizers @ file:///Users/mnachin/executorch/extension/llm/tokenizers
torch==2.9.0.dev20250725
torchao @ file:///Users/mnachin/executorch/third-party/ao
torchaudio==2.8.0.dev20250725
torchdata==0.11.0
torchsr==1.0.4
torchtune==0.6.1
torchvision==0.24.0.dev20250725
```

Subject: [PATCH 050/423] Arm backend: Add arm-baremetal CMake preset (#13042)

- Executorch may be cross compiled for arm-baremetal targets using
'cmake --preset arm-baremetal'
- Adds a new flag EXECUTORCH_BUILD_ARM_ETDUMP used in the preset to easy
enabling of ET_DUMP.
- backend/arm/scripts/build_executorch.sh is updated to use the new
preset with same behaviour as before.

Subject: [PATCH 051/423] NXP backend: Add model input and output quantization
 (#12586)

### Summary

With this change the NeutronConverter can quantize the input and output
tensors (i.e. Input and Output placeholder nodes). There is also a pass
added to consequently remove the Q/DQ nodes for the placeholders, making
the model fully quantized.

### Test plan
Unit tests were updated with respect to newly introduced changes.

Subject: [PATCH 052/423] Add CoreML CI jobs for optimum-executorch models
 (#12870)

This PR:
* Bumps the optimum-executorch pin in our CI
* Adds a new script .ci/scripts/test_huggingface_optimum_model.py to
test optimum-executorch models
* Adds a new trunk job to run CoreML models

Currently the following models are added:
* qwen3 (quantized)
* smollm (quantized)
* llama3 (quantized)
* olmo (quantized)

The following models can run for me locally with the script
.ci/scripts/test_huggingface_optimum_model.py, but are not running in CI
(requires investigation):
* bert (quantized)
* roberta (quantized)
* distilbert (quantized)
* vit

This CI job complements the other CI script .ci/scripts/test_model.sh
that is based on the ExecuTorch examples repo.

### Summary

- Enable Perplexity Evaluation on device with `llama.py`
- Evaluate perplexity after qdq cpu
- Enable quantization to use simple_eval as calibration dataset.
- Enable UT to check perplexity for QWEN, which should be more reliable
than checking the string output.

Will have a follow up PR to address:
- External CI enablement for qwen on x86 (If it does not take too long).
- Hide Logits scale/offset to metadata in model

 ### Additional Configs when running the script
+
+#### Compile Only
 If you would like to compile the model only, we have provided the flag `--compile_only`. Taking LLAMA3.2 as an example:
 ```bash
 python examples/qualcomm/oss_scripts/llama/llama.py -b build-android -m ${SOC_MODEL} --ptq 16a4w --checkpoint consolidated.00.pth --params params.json --tokenizer_model tokenizer.model --llama_model llama3_2 --model_mode hybrid --prefill_ar_len 32 --max_seq_len 128 --prompt "what is 1+1" --compile_only
 ```
 
+#### Pre Generated PTE
 On the other hand, if you already have a pre-compiled .pte model, you can perform inference by providing the flag `--pre_gen_pte` and specifying the folder that contains the .pte model. Taking LLAMA3.2 as an example:
 ```bash
 python examples/qualcomm/oss_scripts/llama/llama.py -b build-android -s ${SERIAL_NUM} -m ${SOC_MODEL} --ptq 16a4w --checkpoint consolidated.00.pth --params params.json --tokenizer_model tokenizer.model --llama_model llama3_2 --model_mode hybrid --prefill_ar_len 32 --max_seq_len 128 --prompt "what is 1+1" --pre_gen_pte ${FOLDER_TO_PRE_GEN_PTE}

 You can enable MaskedSoftmax feature by providing the flag `--enable_masked_softmax`. It is designed to optimize the LLMs accuracy and performance executed on HTP backend. MaskedSoftmax is used to replace the Softmax(Add(In, Mask)) structure in attention block in LLMs during backend optimization. For more details, please refer to QNN documents.
 Note that it is only supported starting from QNN 2.35.
+
+#### Perplexity Evaluation
+This script supports perplexity evaluation and is capable of assessing perplexity scores across 3 phases: prepare_pt2e(CPU FP), convert_pt2e(CPU QDQ), QNN on device.
+
+To evaluate the perplexity across all 3 phases, users should provide the `--eval_perplexity` flag and specify the evaluation task. Please notice when this flag is provided, the `--prompt ${PROMPT}` will be ignored.
+
+For example, using the Qwen model and 1 wikitext sample as the evaluation task, users can assess all 3 phases perplexity score in a single run by including the appropriate configuration:
+```bash
+python examples/qualcomm/oss_scripts/llama/llama.py -b build-android -s ${SERIAL_NUM} -m ${SOC_MODEL} --prompt "What is 1+1?" --temperature 0 --model_mode kv --max_seq_len 1024 --ptq 16a8w --decoder_model qwen2_5 --eval_perplexity --tasks wikitext --limit 1
+```
+
+For the example 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.
+Example:
+```bash
+# 1st run to compile with --limit 1
+python examples/qualcomm/oss_scripts/llama/llama.py -b build-android -s ${SERIAL_NUM} -m ${SOC_MODEL} --prompt "What is 1+1?" --temperature 0 --model_mode kv --max_seq_len 1024 --ptq 16a8w --decoder_model qwen2_5 --eval_perplexity --tasks wikitext --limit 1 --compile_only
+```
+```bash
+# 2nd run to perform QNN device execution with --limit 3
+python examples/qualcomm/oss_scripts/llama/llama.py -b build-android -s ${SERIAL_NUM} -m ${SOC_MODEL} --prompt "What is 1+1?" --temperature 0 --model_mode kv --max_seq_len 1024 --ptq 16a8w --decoder_model qwen2_5 --eval_perplexity --tasks wikitext --limit 3 --pre_gen_pte ${PATH_TO_ARTIFACT_IN_1ST_RUN} --quant_attrs_path ${PATH_TO_ARTIFACT_IN_1ST_RUN}/kv_llama_qnn_quant_attrs.json
+```
+
+#### Tasks quantization calibration
+If `--tasks ${TASK}` is not provided, the program will use `--prompt ${PROMPT}` as the dataset for quantization calibration.
+Regardless of whether `--eval_perplexity` is provided, as long as `--tasks ${TASK}` is specified, the specified tasks will be used for model quantization calibration instead of the prompt.

Subject: [PATCH 056/423] Change default minimum_deployment_target to None and
 support CoreML models with no inputs (#13053)

This PR changes the default minimum_deployment_target in CoreML from the
fixed iOS15 to None. This will automatically select the minimum
deployment target required to export the model.

A warning occurs after export telling the user the deploymnet target
selected, and directing them to specify a specific target if that is
what they need.

This is more in line with how CoreML standalone works.

In addition, this PR allows running CoreML models with no user inputs,
which requires CoreML deployment target iOS18 or higher.

This addresses:

Subject: [PATCH 064/423] Arm backend: Import executorch deps using
 find_package (#13060)

- Renames portable_ops_lib to arm_portable_ops_lib to not conflict with
the op_lib from the executorch_package regestring all ops.
- Adds install target to the ethos_u_delegate to make it findable using
find_package.
- Removes the --whole-archive arg for quantized_ops_lib to avoid
re-registiring runtime error.

Subject: [PATCH 067/423] Arm backend: Move quant util functions to closer to
 usage (#13094)

The following functions are only used in quantization_annotator and can
therefore be moved from arm_quantizer_utils.py to
quantization_annotator.py:

    * is_large_scalar
    * is_non_float_tensor
    * get_node_target

Additionally, is_ok_for_quantization is removed. It combined the
is_large_scalar and is_non_float_tensor checks into one, which is now
done directly where is_ok_for_quantization was used.

Subject: [PATCH 074/423] Qualcomm AI Engine Direct - Runtime Option (#12297)

### Summary
Supporting following options that can be set during both AOT and
runtime:

- Log Level
- Performance Mode
- Profiling Level

### Test plan

- Log Level: Check `debug` message prefix exists.
- Performance Mode: Ensure QNN SDK prints config log for performance,
and ensure burst is faster than high power saver.
- Profiling Level: Turn profiling off in compile spec and add profiling
flag in runtime, ensure profiler gets expected number of events.

+Outputs are returned in two ways:
+- As an array of `Value`s, letting you inspect and cast results yourself.

If the output doesn’t match the expected type (e.g. multiple Values returned when a single object is expected, or a tensor data type mismatch), an invalid type error is thrown.

Subject: [PATCH 084/423] Use temp allocator for kernel registry (#13012)

Summary: When indexing to the registry to get the op, memory is
allocated from the method allocator to instantiate some TensorMeta and
included objects. This memory is only used for that purpose and is not
needed for the entire lifetime of the Method. Thus, we can instead use
temp allocator which can later be reset and free up memory as needed.

Adds ability to specify model_dir to optimum test script. This is
convinient if you want the pte file for local debugging. If no model_dir
is specified, a temp directory is created.

Subject: [PATCH 091/423] [ET-VK][BE] Remove usage of `vTensorPtr` and
 `get_tensor` (#13167)

Note that although the volume of changes in this diff are very high, the changes themselves are extremely mechanical. This diff was written almost entirely with a LLM, but I have looked through each file and validated the changes.

## Changes


This diff updates callsites using `graph->get_tensor(value_ref)` in favor of just using the `ValueRef` directly.

A simple example (and the vast majority of changes in this diff) is a change such as:

```
vTensorPtr tensor = graph->get_tensor(tensor_ref);

some_fn(tensor->sizes());
```

To instead be

```
std::vector<int64_t> tensor_sizes = graph->sizes_of(tensor_ref);
some_fn(tensor_sizes);
```

or

```
some_fn(graph->sizes_of(tensor_ref));
```

## Motivation

Overall, the goal is to make the `get_tensor()` API protected so that it can only be used in specific situations.

In addition to the primary motivation of improving the consistency of API usage throughout the codebase, there is a practical benefit as well. `get_tensor` has a limitation that no values can be added to the graph while the `vTensorPtr` is in scope. Also, forcing tensor modifications via functions like `virtual_resize()` to go through the `ComputeGraph` will allow the graph to track changes for the purposes of determining when a command buffer re-encode or resize propagation is necessary, which will result in performance benefits.

Subject: [PATCH 092/423] [ET-VK][ez] Make `get_tensor()` API protected
 (#13168)

## Changes

As title; make the `get_tensor()` API protected.

## Motivation

See the below diff/PR in the stack. The goal is to encourage operator authors to go through the `ComputeGraph` to access/modify tensors so that the activity can be tracked.

Subject: [PATCH 093/423] Cleaned up Wasm cmake (#13106)

### Summary
Before, if dependencies for the API were not enabled in the cmake
command, you would get linking errors when trying to compile. Now, if
EXECUTORCH_BUILD_WASM is turned on, an error will occur during configure
stage if dependencies were not enabled.

Also changed the API to use executorch_kernels rather than hardcoding in
portable_ops_lib.

For the unit tests, changed the libraries to PRIVATE instead of PUBLIC
and to use `--pre-js` instead of `--post-js` as that is the recommended
way of interfacing with the Embind Module.

### Test plan
```bash
bash scripts/build_wasm_tests.sh
cd cmake-out-wasm/extension/wasm/test/
npm test # after installing Jest
```

+# ExecuTorch Wasm Extension
+
+This directory contains the source code for the ExecuTorch Wasm extension. The extension is a C++ library that provides a JavaScript API for ExecuTorch models. The extension is compiled to WebAssembly and can be used in JavaScript applications.
+
+## Installing Emscripten
+
+[Emscripten](https://emscripten.org/index.html) is necessary to compile ExecuTorch for Wasm. You can install Emscripten with these commands:
+
+```bash
+# Clone the emsdk repository
+git clone https://github.com/emscripten-core/emsdk.git
+cd emsdk
+
+# Download and install version 4.0.10 of the SDK
+./emsdk install 4.0.10
+./emsdk activate 4.0.10
+
+# Add the Emscripten environment variables to your shell
+source ./emsdk_env.sh
+```
+
+## Building ExecuTorch for Wasm
+
+To build ExecuTorch for Wasm, make sure to use the `emcmake cmake` command and to have `EXECUTORCH_BUILD_WASM` enabled. For example:
+
+```bash
+# Configure the build with the Emscripten environment variables
+emcmake cmake . -DEXECUTORCH_BUILD_WASM=ON \
+    -DCMAKE_BUILD_TYPE=Release \
+    -Bcmake-out-wasm
+
+# Build the Wasm extension
+cmake --build cmake-out-wasm --target executorch_wasm -j32
+```
+
+To reduce the binary size, you may also use the selective build options found in the [Kernel Library Selective Build guide](../../docs/source/kernel-library-selective-build.md). You may also use optimized kernels with the `EXECUTORCH_BUILD_KERNELS_OPTIMIZED` option. Portable kernels are used by default.
+
+### Building for Web
+
+In your CMakeLists.txt, add the following lines:
+
+```cmake
+add_executable(executorch_wasm_lib) # Emscripten outputs this as a JS and Wasm file
+target_link_libraries(executorch_wasm_lib PRIVATE executorch_wasm)
+target_link_options(executorch_wasm_lib PRIVATE ...) # Add any additional link options here
+```
+
+You can find the Emscripten link options in the [emcc reference](https://emscripten.org/docs/tools_reference/emcc.html).
+
+Building this should output `executorch_wasm_lib.js` and `executorch_wasm_lib.wasm` in the build directory. You can then use this file in your page.
+
+```html
+<script>
+  // Emscripten calls Module.onRuntimeInitialized once the runtime is ready.
+  var Module = {
+    onRuntimeInitialized: function() {
+      const et = Module; // Assign Module into et for ease of use
+      const model = et.Module.load("mv2.pte");
+      // ...
+    }
+  }
+</script>
+<script src="executorch_wasm_lib.js"></script>
+```
+
+### Building for Node.js
+
+While the standard way to import a module in Node.js is to use the `require` function, doing so does not give you access to the [Emscripten API](https://emscripten.org/docs/api_reference/index.html) which would be stored in the globals. For example, you may want to use the [File System API](https://emscripten.org/docs/api_reference/Filesystem-API.html) in your unit tests, which cannot be done if the library is loaded with `require`. Instead, you can use the `--pre-js` option to prepend your file to the start of the JS output and behave similarly to the example in the [Web build](#building-for-web).
+
+```cmake
+add_executable(my_project) # Emscripten outputs this as a JS and Wasm file
+target_link_libraries(my_project PRIVATE executorch_wasm)
+target_link_options(my_project PRIVATE --pre-js my_code.js) # Add any additional link options here
+```
+
+The output `my_project.js` should contain both the emitted JS code and the contents of `my_code.js` prepended.
+
+## JavaScript API
+
+### Module
+- `static load(data)`: Load a model from a file or a buffer.
+- `getMethods()`: Returns the list of methods in the model.
+- `loadMethod(methodName)`: Load a method from the model.
+- `getMethodMetadata(methodName)`: Get the metadata of a method.
+- `execute(methodName, inputs)`: Execute a method with the given inputs.
+- `forward(inputs)`: Execute the forward method with the given inputs.
+- `delete()`: Delete the model from memory.
+
+### Tensor
+- `static zeroes(shape, dtype=ScalarType.Float)`: Create a tensor of zeros with the given shape and dtype.
+- `static ones(shape, dtype=ScalarType.Float)`: Create a tensor of ones with the given shape and dtype.
+- `static full(shape, value, dtype=ScalarType.Float)`: Create a tensor of the given value with the given shape and dtype
+- `static fromArray(shape, array, dtype=ScalarType.Float, dimOrder=[], strides=[])`: Create a tensor from a JavaScript array.
+- `static fromIter(shape, iter, dtype=ScalarType.Float, dimOrder=[], strides=[])`: Create a tensor from an iterable.
+- `delete()`: Delete the tensor from memory.
+- `scalarType`: The scalar type of the tensor.
+- `data`: The data buffer of the tensor.
+- `sizes`: The sizes of the tensor.
+
+### MethodMeta
+- `name`: The name of the method.
+- `inputTags`: The input tags of the method.
+- `inputTensorMeta`: The input tensor metadata of the method.
+- `outputTags`: The output tags of the method.
+- `outputTensorMeta`: The output tensor metadata of the method.
+- `attributeTensorMeta`: The attribute tensor metadata of the method.
+- `memoryPlannedBufferSizes`: The memory planned buffer sizes of the method.
+- `backends`: The backends of the method.
+- `numInstructions`: The number of instructions in the method.
+- These are value types and do not need to be manually deleted.
+
+### TensorInfo
+- `sizes`: The sizes of the tensor.
+- `dimOrder`: The dimension order of the tensor.
+- `scalarType`: The scalar type of the tensor.
+- `isMemoryPlanned`: Whether the tensor is memory planned.
+- `nBytes`: The number of bytes in the tensor.
+- `name`: The name of the tensor.
+- These are value types and do not need to be manually deleted.
+
+### ScalarType
+- Only `Float` and `Long` are currently supported.
+- `value`: The int constant value of the enum.
+- `name`: The `ScalarType` as a string.
+
+### Tag
+- `value`: The int constant value of the enum.
+- `name`: The `Tag` as a string.
+
+Emscripten's JavaScript API is also avaiable, which you can find more information about it in their [API Reference](https://emscripten.org/docs/api_reference/index.html).

Subject: [PATCH 095/423] Correct the Windows cross-compiling commands (#13071)

### Summary

During the cross-compilation using Clang on Ubuntu for Windows, there
are several commands that are executed on the host and they are failing.

Add the guarding condition which checks for `CMAKE_CROSSCOMPILING` and
picks the Linux alternative.

### Test plan

This adds palletization support for embedding/linear layers in CoreML

Note, this needs to wait for https://github.com/pytorch/ao/pull/2648 to
land in ao + a pin bump in ET before landing.

Subject: [PATCH 098/423] [ET-VK] Add 2D Reduction to Vulkan Backend (#12860)

Summary: This change adds 2D reduction to the Vulkan delegate. Prior to
this change, only 1D reduction was implemented. Models like MobileNetV3
and ResNet do 2D reduction, and their performance was being negatively
impacted by the lack of a 2D reduction Vulkan implementation.

Subject: [PATCH 101/423] Updates to Arm Zephyr CI Add Model Test (#13115)

### Summary
Previously, the `test-models-arm-zephyr` CI job ran the Add model to
test and verify the flow for running ExecuTorch models on a simulated
device running Zephyr RTOS. The original test relied on hard coded paths
and artifacts that made the test unusable for other models. Now, the
test has been templatized so that adding models can be done easily (and
will follow in a future PR).

### Test plan
Manually tested the commands, and the CI job will confirm that the test
still passes.

Subject: [PATCH 105/423] Arm Backend: Improve VGF runtime and update MLSDK
 setup (#13155)

* Adds portability extensions to instance_info
 * Explicitly sets poolSizes in descriptor pool
* Update Arm MLSDK manifest url to default to newly publish repo during
setup.sh
 * Add new exports to setup_path.sh for mlsdk components

Subject: [PATCH 106/423] Arm backend: Remove submodule serialization_lib
 (#13178)

Remove the git submodule serialization_lib since its pointing to an old
0.80 tag and is not used by the arm backend.

Instead this library is now cloned part of the tosa-reference-module
when needed.

Subject: [PATCH 107/423] Arm backend: Move QuantArgs to its own file in
 _passes/ (#13124)

The is part of an effort to reduce the number of functions/classes in
utility files. This class has no reason being in a utility file when it
has a clear purpose on its own.

Subject: [PATCH 109/423] Arm backend: Add index_tensor/index_select to
 unsupported u55 operators (#13176)

index_tensor and index_select both become a GATHER Tosa operators, which
is not support on U55.

Add test cases for U55 for these operators. The test cases verify that
the ops do not get delegated.

 runner (#13177)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ET_NUM_INFERENCES macro can now be set to specify a number of
inferences to run with Arm executor runner.

The StopMeasurements function is also given a new argument, int
num_inferences, in order to display data per inference.

Subject: [PATCH 111/423] [ET-VK] Fix Build Errors in Vulkan Backend (#13170)

This change fixes build issues that arose from the addition of 2D
reduction to the Vulkan backend:

https://github.com/pytorch/executorch/commit/112a09f9b9a6efd8cc8c0959072766bd82d0929e

```get_tensor()``` was moved to be a protected member of ComputeGraph a few minutes before the above commit got merged.

This change also slightly modifies op_registry.py to have a more conservative approach of allowing 2D reduction to be delegated.

Subject: [PATCH 113/423] Default Export for Mv2 with Real Image Input (#13019)

### Summary
When testing executorch inference runners on real MCUs, it's helpful if
the default export of the model includes a real input (rather than just
filled with random values or all 1.0s). This PR does this for the
mobilenet_v2 model, following the steps from the tutorial
[here](https://pytorch.org/hub/pytorch_vision_mobilenet_v2/).


### Test plan
Ran `python -m examples.portable.scripts.export --model_name="mv2"` and
saw the PTE now contains values associated with the `dog.jpg` image.

Subject: [PATCH 115/423] Typo Fix for Default Example Inputs to MobilenetV2
 Export (#13206)

### Summary
[PR](https://github.com/pytorch/executorch/pull/13019) forgot to change
the return example input to use the default samoyed dog image when using
real inputs. This PR fixes that typo.

### Test plan
Now the example runners that use the `mv2` export contain the dog image
in the pte by default.

Subject: [PATCH 116/423] Enabling Dtype Selective Build for Zephyr CI Add
 Model Test (#13191)

### Summary
In the baseline version of this test, only operator selective build is
used. A CMake command line option was created to pass in an exported
model's PTE file via command line so that the model API for data type
selective build can be used. Adding verbose error checking to make logs
more informative.

### Test plan
Ran with and without the flag set, and saw that enabling data type
selective build reduces memory footprint. Specifically for the example
add model, operator library shrinks from ~127KB to ~83KB.

Subject: [PATCH 118/423] Adding Models to Test Matrix for Zephyr CI Test
 (#13193)

### Summary
Previously, only the example Add model was included in the matrix of
models that the Zephyr CI job tests. The Add model isn't very
representative of real-world models, and may give a false sense of
security on the functionality of incorporating ExecuTorch with Zephyr.
This PR adds the simple `Softmax` and `Mobilenet V2` models to the test
matrix. While the `Softmax` model is like the `Add` model (a toy
example), `Mobilenet V2` includes using an image from the `imagenet`
validation set, and verifies that the top predicted label matches
expectation (i.e. predict "Samoyed" as best label). All three of these
tests show example of this flow can be extend further for other models.
Thus this PR integrates these test to ensure compatibility between
ExecuTorch and Zephyr is maintained.

Verified that these models work with the Zephyr ecosystem manually in a
separate docker image.

Subject: [PATCH 122/423] Arm backend: Remove instance checks for Tosa_1.00
 (#13219)

With tosa 0.80 removed there's no need to check which tosa version's
being used.

Subject: [PATCH 124/423] Fix for Type Check in Quantized CPU op_dequantize
 (#13174)

### Summary
When quantizing a model (without delegating to a specific backend), an
exported model relies on the operator library in
`kernels/quantized/cpu/`. Specifically, the essential operation of
`op_dequantize` is performing:

`out = (in - offset) * scale`

where the offset is an integer type. While initially, this offset is
assumed to be an `uint64_t` (see
[here](https://github.com/pytorch/executorch/blob/a44e4aca7cddf91e8ed7282a70d6c40493a50883/kernels/quantized/cpu/op_dequantize.cpp#L426)),
when it is used to perform the operation above, it is cast down to a
`uint32_t` (see
[here](https://github.com/pytorch/executorch/blob/a44e4aca7cddf91e8ed7282a70d6c40493a50883/kernels/quantized/cpu/op_dequantize.cpp#L463)).
It seems an implicit assumption is that the quantization offset is a
`uint32_t` value, and the `uint64_t` declaration is simply safeguarding
for future proofing. In any event, the type check for the offset should
allow the offset to be either `uint32_t` or uint64_t`. This PR allows
for that change.

### Test plan
Tested with mobilenet V2 on Arm backend. Quantized model runner
initially crashed do to this check only allowing the offset to be
`uint64_t`. When examining the values, none were larger than
`UINT32_MAX`, so it should be safe to permit the offset to have
`uint32_t` values. When this change was made, the mobilenet V2 runner
was able to complete.

Subject: [PATCH 126/423] Qualcomm AI Engine Direct - BC CI Fix and Custom
 Annotation Fix (#13212)

### Summary

- This PR will fix BC CI to use the right tokenizer, initially 260k
accidently use 110m tokenizer during runtime.
- Fix custom annotation where conv has bias node.

### Test plan

Subject: [PATCH 133/423] Add deprecation warning for to_edge + to_backend
 workflow in XnnpackPartitioner (#13209)

### Summary
This PR adds a deprecation warning in the XnnpackPartitioner to guide
users away from the deprecated to_edge() + to_backend() workflow and
toward the recommended to_edge_transform_and_lower() flow. We inspect
the call stack in the partitioner to detect when the partitioner is
called from the deprecated workflow and then print out a warning
statement. This helps prevent issues that can arise from the deprecated
workflow.

### Test plan
Added tests testing the deprecation warning functionality in
test_xnnpack_partitioner.py. Tests verify that the warning appears when
using to_edge() + to_backend() and does not appear when using
to_edge_transform_and_lower().

Subject: [PATCH 135/423] Flash Attention Texture Compute Shader for Vulkan
 Backend Delegate (#12982)

Summary: Built flash attention compute shader for Vulkan backend
delegate. The current implementation is not fully optimized, but is
functional. This shader should speed up the SDPA process in the
attention block of transformer inferencing as the previous
implementation used many i/o operations. The implementation includes
proper multi-query attention support for models like LLaMA, uses tiled
block processing to reduce memory usage, and replaces multiple separate
operations (matmul, softmax, masking) with a single efficient compute
shader.

Subject: [PATCH 136/423] Update install_requirements.py to include
 TORCH_NIGHTLY_URL for requirement-examples.txt (#13110)

For failing mosh test,
https://hud.pytorch.org/hud/pytorch/executorch/main/1?per_page=50&name_filter=test-moshi-linux&mergeEphemeralLF=true

First, ./install_executorch.sh correctly installs PyTorch nightly:
Successfully installed torch-2.9.0.dev20250725+cpu

Then processes requirements-examples.txt which contains timm==1.0.7
When installing timm, pip detects a dependency conflict and downgrades
PyTorch to 2.4.1

Let's try adding --extra-index-url

Subject: [PATCH 139/423] [ET-VK] Allow `aten.cat.default` to handle any number
 of input tensors (#13252)

## Context

Previously, I updated the implementation of `aten.cat.default` in D76305343 (#11508) since the original implementation had a bug. The new implementation only supported up to 3 input tensors, but several models require the need for up to 6 input tensors.

This diff updates the capabilities of the `concat` op so that any arbitrary number of input tensors may be accepted.

## Changes

* Update implementation of the concat shader to be able to be called repeatedly, allowing support for any number of input tensors.

Subject: [PATCH 140/423] [ET-VK][ez] Fix registration for convolution operator
 (#13253)

## Context

Update the registration of the convolution operator to indicate that the weight tensor is prepacked and should not undergo normal texture limits checking. The current registration may cause valid convolution operators to not be partitioned since the export logic will think the weight tensor is non representable using channels packed textures. An example weight size would be something like [256, 256, 1, 1] which would result in a texture with extents [1, 1, 16384] which may exceed texture limits on some machines.

Subject: [PATCH 141/423] [ET-VK] 8/n Split dispatches between multiple command
 buffers. This diff adds a config to limit the maximum number of command
 buffers created when splitting execution between multiple command buffers.
 (#13204)

This diff adds a config to limit the maximum number of command buffers created when splitting execution between multiple command buffers."

This diff introduces a new configuration option, `execute_max_cmds`, to limit the maximum number of command buffers created when splitting execution between multiple command buffers. This feature allows for more efficient management of command buffers, particularly in scenarios where the number of nodes in the graph is large.

- * The macro expansion uses __VA_ARGS__ to accept any number of arguments and

- * ET_INTERNAL_CHECK_OK_OR_RETURN_ERROR_SELECT which takes the arguments and

- * matches this sequence to the correct number of arguments provided.
- *
- * If two arguments are passed, ET_INTERNAL_CHECK_OK_OR_RETURN_ERROR_2 is
- * selected, suitable for cases where an error code and a custom message are
- * provided. If only one argument is passed,
- * ET_INTERNAL_CHECK_OK_OR_RETURN_ERROR_1 is selected, which is used for cases
- * with just an error code.
- *
- * Usage:
- * ET_CHECK_OK_OR_RETURN_ERROR(error_code); // Calls v1
- * ET_CHECK_OK_OR_RETURN_ERROR(error_code, "Error message", ...); // Calls v2

Subject: [PATCH 143/423] Require setting all inputs before execution. (#13207)

Summary: Method never cared to check all the inputs were properly set
before execution and basically used some default allocated memory for
unset inputs. Here we introduce a safety check to guarantee users don't
forget to set all inputs explicitly.

Subject: [PATCH 146/423] Fix temp memory allocation issue in torch.topk
 operations (#12810)

Summary: Fixes issue https://github.com/pytorch/executorch/issues/8700

changed the temp_allocator_ from a
MemoryAllocator with null buffer to a MallocMemoryAllocator that can
 dynamically allocate memory as needed.

Test plan: To verify the fix, a new end-to-end test suite has been added
(`test/end2end/test_temp_allocator_fix.py`). This suite includes tests
for `torch.topk` both with and without the `out` parameter, as well as a
test with a larger input to ensure the allocator can handle more
significant memory requirements. These tests now pass with the
implemented fix. I will now write the PR description.

Subject: [PATCH 149/423] Arm backend: Generate kernel registration lib from
 .pte (#13220)

- Moves the arm_portable_op_lib target into the executor_runner
CMakeLists.txt
- Use the OPS_FROM_MODEL arg to generate the arm_portable_op_lib if
possible
- Adds possibility of setting EXECUTORCH_ENABLE_DTYPE_SELECTIVE_BUILD
when building the executor_runner.
- Makes cortex_m targets findeable using find_package to avoid
rebuilding.

-The `--portable_kernels` flag can be used to set the build flag `EXECUTORCH_SELECT_OPS_LIST` when running `backends/arm/scripts/build_portable_kernels.sh` that will decide the number of portable operators included in the build and are available at runtime. It must match with `.pte` file's requirements, otherwise you will get `Missing Operator` error at runtime.
-
-For example, there  in the command line above, to run SoftmaxModule, you only included the softmax CPU operator. Similarly, to run AddModule in a non-delegated manner you will need add op and so on. As you might have already realized, for the delegated operators, which will be executed by the Arm backend delegate, you do not need to include those operators in this list. This is only for *non-delegated* operators.

+Note, you have to generate a new `executor-runner` binary if you want to change the model or the `.pte` file. This constraint is from the constrained bare-metal runtime environment you have for Corstone-300/Corstone-320 platforms. The build also generates a kernel registration library for the relevant operators which could not be delegated to the EthosU, see the [Kernel Library Selective Build documentation](https://docs.pytorch.org/executorch/stable/kernel-library-selective-build.html).
 
 This step is executed by the build_executor_runner.sh script, which is invoked from the run.sh in the backends/arm/scripts folder.

Subject: [PATCH 151/423] Arm backend: Use bucket approach in
 fuse_equal_placeholder_pass (#13271)

Verified to catch same dupes as before in lstm and mv2.

Instead of comparing all placeholders to each other, compute a hash use
as key in dictionary. Equal placeholder -> equal key. If an entry in the
dictionary has multiple values, we have duplicates.

This is a ~O(N) algorithm compared to earlier O(N^2). This can be seen
by measuring the speedup for lstm vs. mv2

lstm: 120 placeholders (116 dupes) 0.4s -> 0.3s

mv2: 318 placeholders (98 dupes) ~15s -> 0.5s

Subject: [PATCH 156/423] Add cmake-format linter (#12868)

This uses the adapter I added to lintrunner-adapters in
https://github.com/justinchuby/lintrunner-adapters/pull/117, which was
released in the newest lintrunner-adapters release.

Subject: [PATCH 158/423] Always run build-presets workflow on PRs/pushes
 (#13243)

The build-presets workflow currently runs only when the workflow file
itself is updated. As we update docs to recommend using presets, we
should run this job on all PRs.

Note that the Windows preset is currently reporting success despite
failing to actually build. I'm intending to resolve that shortly as a
follow-up.

Subject: [PATCH 159/423] Add _clone_dim_order portable kernel (#12974)

### Summary
This is PR 1 of 3 implementing a dim order aware clone op.

Currently, clone ops are removed during export as no-ops, causing memory
layout (dim order) changes to be lost. This can cause backend failures,
incorrect outputs when ops expect specific layouts, and performance
degradation. This set of PRs introduces a dim order aware clone op,
`_clone_dim_order`, which preserves memory layout changes by explicitly
storing dim order information. This is implemented by replacing standard
clone ops with this variant during export and updating the clone removal
transform to preserve clones that change layout.

This PR adds the portable CPU kernel for the `_clone_dim_order` op,
implementing a clone variant that preserves dim order at runtime. The
portable kernel validates dtype and layout compatibility, resizes the
output tensor if needed, and performs an element wise clone of the
tensors.

Note: A future PR will add the ATen kernel for `_clone_dim_order`.

Related PRs:
- PR 2: [#12971](https://github.com/pytorch/executorch/pull/12971) -
Register `_clone_dim_order` op and map `aten.clone`
- PR 3: [#12976](https://github.com/pytorch/executorch/pull/12976) -
Update RemoveCloneOpsTransform to be dim_order aware

Fixes #12645

### Test plan
Added kernel runtime tests to verify:
- Tensors of all real dtypes are cloned correctly.
- Failure when input and output tensor shapes mismatch.
- Failure with unsupported memory formats.
- Failure when `non_blocking=true` since the portable kernel only
supports blocking data transfer.
- Dynamic shape outputs are cloned with correct values.
- Layout conversions are cloned correctly for `contiguous` to
`channels_last`, `channels_last` to `contiguous`, and `channels_last` is
preserved.

All runtime tests pass via:
`build-ninja/kernels/test/portable_kernels_test`

 Instead of needing to manually write code to call torch.export(), use ExecuTorch's assortment of lowering APIs, or even interact with TorchAO quantize_ APIs for quantization, we have provided an out of box experience which performantly exports a selection of supported models to ExecuTorch.
 
+## Prerequisites
+
+The LLM export functionality requires the `pytorch_tokenizers` package. If you encounter a `ModuleNotFoundError: No module named 'pytorch_tokenizers'` error, install it from the ExecutorTorch source code:
+
+```bash
+pip install -e ./extension/llm/tokenizers/
+```
+
+## Supported Models
+
 As of this doc, the list of supported LLMs include the following:
 - Llama 2/3/3.1/3.2
 - Qwen 2.5/3

 library by default (#12257)

Other targets seem to just use whatever the default configuration is.
Make this one work the same.

Subject: [PATCH 166/423] Arm backend: Use padding for the base64 coded ETDump
 string (#13276)

This fix "base64: invalid input" errors you got sometimes when
converting it to a file.

This change also avoid using ' ', '\r', and '\n' in the base64 string
for a cleaner string.

Subject: [PATCH 172/423] Arm backend: Remove function getNodeArgs (#13316)

The function was only used in one place and it was only a couple of
lines so the logic was moved to where the function was originally
called, which is in process_node.py.

Subject: [PATCH 181/423] [Backend Tester] Add Qualcomm tester and register
 flow (#12739)

Add a tester class implementation for Qualcomm and register the test
flow with the backend tester.

Note that QNN pybindings are planned but not yet functional.

Subject: [PATCH 182/423] [Backend Tester] Add CSV report generation (#12741)

Add some initial CSV report generation, detailing results and parameters
for each individual test. Delegation statistics and such will come next.
I've also added a basic test for the report generation, which I will
expand upon in this stack.

Here's some sample output from running add tests for XNNPACK:
```
Test ID,Test Case,Backend,Flow,Result,Dtype
test_add_dtype_float32_xnnpack,test_add_dtype,xnnpack,xnnpack,Success (Delegated),torch.float32
test_add_dtype_float32_xnnpack_static_int8,test_add_dtype,xnnpack,xnnpack_static_int8,Success (Delegated),torch.float32
test_add_f32_alpha_xnnpack,test_add_f32_alpha,xnnpack,xnnpack,Fail (Quantize),
test_add_f32_alpha_xnnpack_static_int8,test_add_f32_alpha,xnnpack,xnnpack_static_int8,Fail (Quantize),
test_add_f32_bcast_first_xnnpack,test_add_f32_bcast_first,xnnpack,xnnpack,Success (Delegated),
test_add_f32_bcast_first_xnnpack_static_int8,test_add_f32_bcast_first,xnnpack,xnnpack_static_int8,Success (Delegated),
test_add_f32_bcast_second_xnnpack,test_add_f32_bcast_second,xnnpack,xnnpack,Success (Delegated),
test_add_f32_bcast_second_xnnpack_static_int8,test_add_f32_bcast_second,xnnpack,xnnpack_static_int8,Success (Delegated),
test_add_f32_bcast_unary_xnnpack,test_add_f32_bcast_unary,xnnpack,xnnpack,Success (Delegated),
test_add_f32_bcast_unary_xnnpack_static_int8,test_add_f32_bcast_unary,xnnpack,xnnpack_static_int8,Success (Delegated),
```

Subject: [PATCH 183/423] Update build from source docs (#13210)

### Summary
Overhaul the "Building from Source" doc page. The primarily intent of
these changes is to document CMake presets and the various build options
that we expose. However, I also did a pass on the existing contents of
the file to improve formatting and clarity.

I've re-organized the page to clearly delineate environment setup,
python install, and native build. It should flow better and be easier to
read.

### Test plan
I have built the docs locally to inspect the contents for formatting and
correctness.

Preview page:

-
-
-Linux (x86_64)
-- CentOS 8+
-- Ubuntu 20.04.6 LTS+
-- RHEL 8+

-### Software
+ExecuTorch is tested on the following systems, although it should also work in similar environments.
+
+ * Linux (x86_64)
+    * CentOS 8+
+    * Ubuntu 20.04.6 LTS+
+    * RHEL 8+
+ * macOS (x86_64/ARM64)
+    * Big Sur (11.0)+
+ * Windows (x86_64)
+    * Windows Subsystem for Linux (WSL) with any of the Linux options
+    * Windows 10+ with Visual Studio 2022+ (experimental)
+
+### Software Requirements
 * `conda` or another virtual environment manager
-  - We recommend `conda` as it provides cross-language
+  - `conda` is recommended as it provides cross-language
     support and integrates smoothly with `pip` (Python's built-in package manager)
   - Otherwise, Python's built-in virtual environment manager `python venv` is a good alternative.
 * `g++` version 7 or higher, `clang++` version 5 or higher, or another
   C++17-compatible toolchain.
 * `python` version 3.10-3.12
+* `Xcode Command Line Tools` (macOS only)
 * `ccache` (optional) - A compiler cache that speeds up recompilation
 
+Additional dependencies will be installed automatically when running the [Python installation](#building-the-python-package).
 Note that the cross-compilable core runtime code supports a wider range of
 toolchains, down to C++17. See the [Runtime Overview](runtime-overview.md) for
 portability details.
 
 ## Environment Setup

-   ```
+## Building the Python package
+  To build and install the ExecuTorch Python components, used for PTE creation and Python runtime bindings, run the following command.
+  This will install the ExecuTorch python package and its dependencies into the active Python environment.
 
-## Install ExecuTorch pip package from source
    ```bash
-   # Install ExecuTorch pip package and its dependencies, as well as
-   # development tools like CMake, and backend support for XNNPACK and CoreML.
-   # If developing on a Mac, make sure to install the Xcode Command Line Tools first.
-   # Intel-based macOS systems require building PyTorch from source (see below)
+   # Install ExecuTorch pip package and its dependencies.
    ./install_executorch.sh
    ```
 
-   See the [PyTorch instructions](https://github.com/pytorch/pytorch#installation) on how to build PyTorch from source.

-   Use the [`--use-pt-pinned-commit` flag](../../install_executorch.py) to install ExecuTorch with an existing PyTorch build:
+  * `--clean`: Removes build artifacts.
+  * `--editable`: Install the ExecuTorch python package in editable mode (see [Editable Install](#editable-install)).
+  * `--minimal`: Install only the minimal set of dependencies required to run ExecuTorch. Do not install dependencies for examples.
+  * `--use-pt-pinned-commit`: Install the pinned PyTorch commit. When not specified, the latest PyTorch nightly build is installed.
 
-   ```bash
-   ./install_executorch.sh --use-pt-pinned-commit

-   For Intel-based macOS systems, use the [`--use-pt-pinned-commit --minimal` flags](../../install_executorch.py):
-   ```bash
-   ./install_executorch.sh --use-pt-pinned-commit --minimal
-   ```
+  For Intel-based macOS systems, use `--use-pt-pinned-commit --minimal`. As PyTorch does not provide pre-built binaries for Intel Mac, installation requires building PyTorch from source. Instructions can be found in [PyTorch Installation](https://github.com/pytorch/pytorch#installation).

-  operator/kernel definitions or backend definitions.
-- `libportable_kernels.a`: The implementations of ATen-compatible operators,

-- `libportable_kernels_bindings.a`: Generated code that registers the contents
-  of `libportable_kernels.a` with the runtime.
-  - NOTE: This must be linked into your application with a flag like
-    `-Wl,-force_load` or `-Wl,--whole-archive`. It contains load-time functions
-    that automatically register the kernels, but linkers will often prune those
-    functions by default because there are no direct calls to them.
-- `executor_runner`: An example tool that runs a `.pte` program file using all
-  `1` values as inputs, and prints the outputs to stdout. It is linked with
-  `libportable_kernels.a`, so the program may use any of the operators it
-  implements.
+## Building the C++ Runtime

+### Building
 
-### CMake build options
+Build all targets with `cmake --build`.
 
-The release build offers optimizations intended to improve performance and reduce binary size. It disables program verification and executorch logging, and adds optimizations flags.

+> **_TIP:_** For faster rebuilds, consider installing ccache (see [Compiler Cache section](#compiler-cache-ccache) above). On first builds, ccache populates its cache. Subsequent builds with the same compiler flags can be significantly faster.
+
+### Build Presets
+
+ExecuTorch provides fine-grained control over what is built, as described in [Build Options](#build-options). These options are grouped into CMake presets to cover common scenarios, while providing the ability to override individual options. Presets can be specified when configuring CMake by specifying `--preset [name]` when configuring.
+
+Preset values for common scenarios are listed below. Using a platform preset is recommended to avoid needing to specify many fine-grained build options.
+
+ * `arm-baremetal` - Build for bare-metal ARM targets.
+ * `ios` - Build features and backends common for iOS targets.
+ * `macos` - Build features and backends common for Mac targets.
+ * `linux` - Build features and backends for Linux targets.
+ * `llm` - Build Large Language Model-specific features.
+ * `profiling` - Build the ExecuTorch runtime with profiling enabled.
+ * `zephyr` - Build for Zephyr RTOS.
+
 ```bash
--DCMAKE_BUILD_TYPE=Release \
--DEXECUTORCH_OPTIMIZE_SIZE=ON
+# Configure the build with the ios preset.
+cmake .. --preset ios
+```
+
+### CMake Targets and Libraries
+
+To link against the ExecuTorch framework from CMake, the following top-level targets are exposed:
+
+ * `executorch::backends`: Contains all configured backends.
+ * `executorch::extensions`: Contains all configured extensions.
+ * `executorch::kernels`: Contains all configured kernel libraries.
+
+The backends, extensions, and kernels included in these targets are controlled by the various `EXECUTORCH_` CMake options specified by the build. Using these targets will automatically pull in the required dependencies to use the configured features.
+
+### Running an Example Model
+
+The example `executor_runner` binary can be used to run a model and sanity-check the build. Run the following commands to generate and run a simple model.
+You should see the message "Model executed successfully" followed by the output values.

+ * `EXECUTORCH_BUILD_MPS` - Build the Apple Metal Performance Shader backend.
+ * `EXECUTORCH_BUILD_NEURON` - Build the MediaTek Neuron backend.
+ * `EXECUTORCH_BUILD_OPENVINO` - Build the Intel OpenVINO backend.
+ * `EXECUTORCH_BUILD_QNN` - Build the Qualcomm AI Engine backend.
+ * `EXECUTORCH_BUILD_VGF` - Build the ARM VGF backend.
+ * `EXECUTORCH_BUILD_VULKAN` - Build the Vulkan GPU backend.
+ * `EXECUTORCH_BUILD_XNNPACK` - Build the XNNPACK CPU backend.
 
-To generate a simple model file, run the following command from the ExecuTorch directory. It
-will create a file named "add.pte" in the current directory.
-```
-python -m examples.portable.scripts.export --model_name="add"

+ExecuTorch extensions provide optional functionality outside of the core runtime. As the core runtime is designed to run in constrained environments, these features are typically disabled by default. Extensions include higher-level APIs (Module and Tensor), multi-threading support (Threadpool), training, and more.

- * `executorch::extensions`: Contains all configured extensions.
- * `executorch::kernels`: Contains all configured kernel libraries.
+#### Logging
 
-The backends, extensions, and kernels included in these targets are controlled by the various `EXECUTORCH_` CMake options specified by the build.
+Logging is enabled by default in debug builds and disabled in release. When enabled, the default log level is Info. Both log enable and level can be overriden with options. See [Logging](using-executorch-runtime-integration.md#logging). Disabling logging and decreasing log verbosity will reduce binary size by stripping unused strings from the build.

+With the NDK installed, the `build_android_library.sh` script will build the ExecuTorch Java AAR. This file contains the ExecuTorch Java bindings
+and native code. See [Using the AAR File](using-executorch-android.md#using-aar-file) for usage.
 
-#### Create and activate the conda environment:
 ```bash

-conda activate et
+export ANDROID_ABIS=arm64-v8a
+export BUILD_AAR_DIR=aar-out
+mkdir -p $BUILD_AAR_DIR
+sh scripts/build_android_library.sh
 ```
 
-### Check Symlinks
-Set the following environment variable to enable symlinks:
-```bash
-git config --global core.symlinks true
-```
+### Building the Example Runner
 
-### Set up ExecuTorch
-Clone ExecuTorch from the [official GitHub repository](https://github.com/pytorch/executorch).
+The native executor runner can be cross-compiled for android and deployed via ADB. This step is intended as
+an example of CMake cross compilation and is not necessary for integration into an app.
 
 ```bash
-git clone --recurse -submodules https://github.com/pytorch/executorch.git
-```
+# Run the following lines from the `executorch/` folder
+./install_executorch.sh --clean

+cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake  -DANDROID_ABI=arm64-v8a ..
 
-### Run the Setup Script
+cd  ..
+cmake --build  cmake-android-out  -j9
 
-Currently, there are a lot of components that are not buildable on Windows. The below instructions install a very minimal ExecuTorch which can be used as a sanity check.

-#### Move into the `executorch` directory
-```bash
-cd executorch
+adb shell  "/data/local/tmp/executorch/executor_runner --model_path /data/local/tmp/executorch/add.pte"
 ```

+
+## Cross-Compiling for iOS
+
+For iOS, we'll build [frameworks](https://developer.apple.com/documentation/xcode/creating-a-multi-platform-binary-framework-bundle) instead of static libraries. The frameworks contain the compiled ExecuTorch runtime and public headers.
+
+### Pre-requisites
+
+* Install Xcode from the
+[Mac App Store](https://apps.apple.com/app/xcode/id497799835) and install
+the Command Line Tools using the terminal.
+
 ```bash
-./install_executorch.bat --clean
+xcode-select --install
 ```
 
-#### Run the setup script.
-You could run the .bat file or the python script.
+### Building
+
+1. Build the frameworks:
+
 ```bash
-./install_executorch.bat
-# OR
-# python install_executorch.py
+./scripts/build_apple_frameworks.sh
 ```
 
-### Export MobileNet V2
+Run the above command with `--help` flag to learn more on how to build additional backends
+(like [Core ML](backends-coreml.md), [MPS](backends-mps.md) or XNNPACK), etc.
+Note that some backends may require additional dependencies and certain versions of Xcode and iOS.
+See backend-specific documentation for more details.
 
-Create the following script named export_mv2.py
+2. Copy over the generated `.xcframework` bundles to your Xcode project, link them against
+your targets and don't forget to add an extra linker flag `-all_load`.
 
-```bash
-from torchvision.models import mobilenet_v2
-from torchvision.models.mobilenetv2 import MobileNet_V2_Weights

+> **_NOTE_** `$miniconda_dir` is the directory where you installed miniconda. This is `“C:\Users\<username>\AppData\Local”` by default.
 
-### Android
+### Running an Example Model
 
-#### Building executor_runner shell binary
-- Prerequisite: [Android NDK](https://developer.android.com/ndk), choose one of the following:
-  - Option 1: Download Android Studio by following the instructions to [install ndk](https://developer.android.com/studio/projects/install-ndk).
-  - Option 2: Download Android NDK directly from [here](https://developer.android.com/ndk/downloads).
+To validate the installation by running a model, create a file named export_mv2.py. Then, run the powershell commands to export and run the model.
+The expected output is a tensor of size 1x1000, containing class scores.
 
-Assuming Android NDK is available, run:
-```bash
-# Run the following lines from the `executorch/` folder
-./install_executorch.sh --clean
-mkdir cmake-android-out && cd cmake-android-out
-
-# point -DCMAKE_TOOLCHAIN_FILE to the location where ndk is installed
-cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake  -DANDROID_ABI=arm64-v8a ..
-
-cd  ..
-cmake --build  cmake-android-out  -j9
-
-adb shell mkdir -p /data/local/tmp/executorch
-# push the binary to an Android device
-adb push  cmake-android-out/executor_runner  /data/local/tmp/executorch
-# push the model file
-adb push  add.pte  /data/local/tmp/executorch
+```py
+# export_mv2.py

-```
+mv2 = mobilenet_v2(weights=MobileNet_V2_Weights.DEFAULT).eval()
+example_inputs = (torch.randn((1, 3, 224, 224)),)
 
-#### Building AAR for app integration from source
-- Prerequisite: Android NDK from the previous section, and Android SDK (Android Studio is recommended).
+program = to_edge_transform_and_lower(
+  torch.export.export(model, example_inputs)
+).to_executorch()
 
-Assuming Android NDK and SDK is available, run:
-```bash
-export ANDROID_ABIS=arm64-v8a
-export BUILD_AAR_DIR=aar-out
-mkdir -p $BUILD_AAR_DIR
-sh scripts/build_android_library.sh
+with open("mv2_xnnpack.pte", "wb") as file:
+    executorch_program.write_to_file(file)
 ```
 
-This script will build the AAR, which contains the Java API and its corresponding JNI library. Please see
-[this documentation](using-executorch-android.md#using-aar-file) for usage.
-
-### iOS
-
-For iOS we'll build [frameworks](https://developer.apple.com/documentation/xcode/creating-a-multi-platform-binary-framework-bundle) instead of static libraries, that will also contain the public headers inside.
-
-1. Install Xcode from the
-[Mac App Store](https://apps.apple.com/app/xcode/id497799835) and then install
-the Command Line Tools using the terminal:
-
 ```bash
-xcode-select --install
+python .\\export_mv2.py
+.\\cmake-out\\backends\\xnnpack\\Release\\xnn_executor_runner.exe --model_path=.\\mv2_xnnpack.pte
 ```
 
-2. Build the frameworks:
-
 ```bash
-./scripts/build_apple_frameworks.sh
+Output 0: tensor(sizes=[1, 1000], [
+  -0.50986, 0.30064, 0.0953904, 0.147726, 0.231205, 0.338555, 0.206892, -0.0575775, … ])
 ```
 
-Run the above command with `--help` flag to learn more on how to build additional backends
-(like [Core ML](backends-coreml.md), [MPS](backends-mps.md) or XNNPACK), etc.
-Note, some backends may require additional dependencies and certain versions of Xcode and iOS.

Subject: [PATCH 186/423] [Backend Tester] Add tensor error statistic reporting
 (#12809)

Report various error statistics for the test outputs, including SQNR,
mean absolute error (MAE), and L2 norm. These are saved in the detail
report per test case.

As an example, here is the output from Core ML running MobileNet V2
(roughly formatted from csv -> sheets -> markdown):
```
Output 0 Error Max	Output 0 Error MAE	Output 0 Error MSD	Output 0 Error L2	Output 0 SQNR
0.0005887411535		0.0001199183663		2.32E-06		0.004750485188		41.28595734

Subject: [PATCH 187/423] [Backend Tester] Report quantization and lowering
 times (#12838)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Track and report the time taken to quantize and lower in the backend
test flow. Include this information in the generated report for each
test case.

Example output (from testing add operator):
Test ID | Test Case | Backend | Flow | Result | Quantize Time (s) |
Lowering Time (s)
-- | -- | -- | -- | -- | -- | --
test_add_dtype_float32_coreml | test_add_dtype | coreml | coreml |
Success (Delegated) |   | 0.69
test_add_dtype_float32_coreml_static_int8 | test_add_dtype | coreml |
coreml_static_int8 | Success (Delegated) | 8.73 | 0.88

Subject: [PATCH 188/423] Added ETDump to Wasm (#13304)

### Summary
Turning on the `EXECUTORCH_ENABLE_EVENT_TRACER` option will enable event
tracing in the Wasm module API. The results can be obtained with the
`etdump()` method.

### Test plan
Added two tests depending on whether `EXECUTORCH_ENABLE_EVENT_TRACER` is
turned on or not. Added the `--enable-etdump` option to
`scripts/build_wasm_tests.sh` which turns on the above option.

Added configurations to the `unittest-wasm-bindings` CI test to run with
and without `--enable-etdump`.

Subject: [PATCH 191/423] [ET-VK] Add optional blocklist and allowlist to
 vulkan partitioner to aid debugging (#13326)

Summary:
## Changes

* Add `operator_allowlist` and `operator_blocklist` optional arguments
to `VulkanPartitioner`
* `operator_blocklist` will prevent operators in the block list to be
lowered to Vulkan
* `operator_allowlist` will only allow operators in the allow list to be
lowered to Vulkan
* `operator_allowlist` takes precedence over `operator_blocklist`

## Context

When debugging models, it is useful to be able to prevent certain
operators from being lowered to Vulkan, or to only allow certain
operators from being lowered to Vulkan. This can help isolate which ops
are causing model output to be incorrect.

Test Plan:
## Test Plan

Tested this feature locally while debugging example models.

Subject: [PATCH 192/423] [ET-VK][ez] Fix `vulkan_schema` interface and link
 Vulkan to pybindings (#13327)

Summary:
## Changes

First, small update to `vulkan_schema` interface in the
`CMakeLists.txt`, which fixes a build error like:

```
  CMake Error in backends/vulkan/CMakeLists.txt:
    Target "vulkan_schema" INTERFACE_INCLUDE_DIRECTORIES property contains
    path:

      "/pytorch/executorch/pip-out/temp.linux-x86_64-cpython-310/cmake-out/schema/include"

    which is prefixed in the build directory.
```

Then, make the pybindings link against to the vulkan backend if it is
built. This allows model testing through Python via
`_load_for_executorch_from_buffer`.

Test Plan:
CI

+# Vulkan Delegate Export Examples
+
+This directory contains scripts for exporting models with the Vulkan delegate in ExecuTorch. Vulkan delegation allows you to run your models on devices with Vulkan-capable GPUs, potentially providing significant performance improvements over CPU execution.
+
+## Scripts
+
+- `export.py`: Basic export script for models to use with Vulkan delegate
+- `aot_compiler.py`: Advanced export script with quantization support
+
+## Usage
+
+### Basic Export
+
+```bash
+python -m executorch.examples.vulkan.export -m <model_name> -o <output_dir>
+```
+
+### Export with Quantization (Experimental)
+
+```bash
+python -m executorch.examples.vulkan.aot_compiler -m <model_name> -q -o <output_dir>
+```
+
+### Dynamic Shape Support
+
+```bash
+python -m executorch.examples.vulkan.export -m <model_name> -d -o <output_dir>
+```
+
+### Additional Options
+
+- `-s/--strict`: Export with strict mode (default: True)
+- `-a/--segment_alignment`: Specify segment alignment in hex (default: 0x1000)
+- `-e/--external_constants`: Save constants in external .ptd file (default: False)
+- `-r/--etrecord`: Generate and save an ETRecord to the given file location
+
+## Examples
+
+```bash
+# Export MobileNetV2 with Vulkan delegate
+python -m executorch.examples.vulkan.export -m mobilenet_v2 -o ./exported_models
+
+# Export MobileNetV3 with quantization
+python -m executorch.examples.vulkan.aot_compiler -m mobilenet_v3 -q -o ./exported_models
+
+# Export with dynamic shapes
+python -m executorch.examples.vulkan.export -m mobilenet_v2 -d -o ./exported_models
+
+# Export with ETRecord for debugging
+python -m executorch.examples.vulkan.export -m mobilenet_v2 -r ./records/mobilenet_record.etrecord -o ./exported_models
+```
+
+## Supported Operations
+
+The Vulkan delegate supports various operations including:
+
+- Basic arithmetic (add, subtract, multiply, divide)
+- Activations (ReLU, Sigmoid, Tanh, etc.)
+- Convolutions (Conv1d, Conv2d, ConvTranspose2d)
+- Pooling operations (MaxPool2d, AvgPool2d)
+- Linear/Fully connected layers
+- BatchNorm, GroupNorm
+- Various tensor operations (cat, reshape, permute, etc.)
+
+For a complete list of supported operations, refer to the Vulkan delegate implementation in the ExecuTorch codebase.
+
+## Debugging and Optimization
+
+If you encounter issues with Vulkan delegation:
+
+1. Use `-r/--etrecord` to generate an ETRecord for debugging
+2. Check if your operations are supported by the Vulkan delegate
+3. Ensure your Vulkan drivers are up to date
+4. Try using the export script with `--strict False` if strict mode causes issues
+
+## Requirements
+
+- Vulkan runtime libraries (libvulkan.so.1)
+- A Vulkan-capable GPU with appropriate drivers
+- PyTorch with Vulkan support

Subject: [PATCH 196/423] [Backend Tester] Add portable test flow (#13250)

Add a portable tester flow to the backend tester. This is mainly
intended to help validate the test suite and to get baseline numbers to
compare against delegated results.

Subject: [PATCH 205/423] Arm backend: Run pytest model tests in parallell
 (#13322)

Reduces time of pytest model jobs with ~50%. Upstream ci tested
successfully 4 times, and easy to revert if it turns out to be flaky.

Subject: [PATCH 209/423] Arm backend: Remove submodule serialization_lib
 (#13182)

Remove the git submodule serialization_lib since its pointing to an old
0.80 tag and is not used by the arm backend.

Instead this library is now cloned part of the tosa-reference-module
when needed.

Subject: [PATCH 211/423] Fix torchao deps (#13107)

This PR

* Renames EXECUTORCH_BUILD_TORCHAO to EXECUTORCH_BUILD_KERNELS_TORCHAO
to be more in line with other kernel options (e.g.,
EXECUTORCH_BUILD_KERNELS_OPTIMIZED)
* Fixes torchao lowbit kernel dependencies in xcframeworks
* Adds torchao lowbit kernels to the swift package

+(If you'd like lowbit to use KleidiAI when available, you can instead install with `EXECUTORCH_BUILD_KERNELS_TORCHAO=1 TORCHAO_BUILD_KLEIDIAI=1 python install_executorch.py`.)

 Also note that low-bit quantization often requires QAT (quantization-aware training) to give good quality results.

Subject: [PATCH 212/423] Revert "Add TorchAO wrapper config to allow filter_fn
 for quantize_ (#13264)" and "Add coreml quant recipes (#13265)" (#13374)

This reverts commit 0a7cea8ca6bc78f42353fba6b0e7b791ff31b992 and
310a05d395e640d95f0f6e4cde4701a22e796ca5. It appears that #13264 broke
unittest jobs and #13265 depends on it.

Subject: [PATCH 215/423] Support for Running Arm Zephyr Toolchain on aarch64
 Host Machines (#13335)

### Summary
When testing ExecuTorch with Arm devices running Zephyr, only the
toolchain download path for the x86-64 host was included. This PR adds
the path for a aarch64 machine, so that that Zephyr flows can be run and
validated on aarch64 machines.

Subject: [PATCH 216/423] [ET-VK] Better work group sizes for matmul (#13378)

## Context

Currently `default_pick_local_wg_size()` (which internally calls `ComputeGraph::create_local_wg_size`) is used to select the local work group size for matrix multiplication ops. However, these functions currently bias the size of the local work group towards the largest dim of the global work group producing local wg sizes like

for matrix multiplication shaders. This behaviour was introduced in D64418632 / #6409.

However, through experimental testing a "square" work group size of `{8, 8, 1}` works a lot better for matrix multiplication shaders. The theoretical analysis for this behaviour is that the local work group size determines the memory locations that need to be loaded to compute the overall work group. For a work group with size `{W, H, 1}` the data required to compute the output would be `W * OUTPUT_TILE_W` columns of the weight tensor and `H * OUTPUT_TILE_H` rows of the input tensor. Note that all work group items in the same W index will be requesting the same columns from the weight tensor, and all work group items in the same H index will be requesting the same rows from the input tensor.

If `H==W`, then that "balances" the amount of data needed to loaded from each input tensor and may result in better data sharing behaviour among all work group items. Assuming `OUTPUT_TILE_W == OUTPUT_TILE_H == 1`, a local work group of size `{64, 1, 1}` would require 1 unique row from the input tensor an 64 unique columns to be loaded from the weight tensor, resulting in `(1 + 64) * K = 65K` elements to be loaded in total, where K is the size of the shared reduction dim. Conversely, a local work group of size `{8, 8, 1}` would require 8 unique rows / 8 unique columns resulting in only `(8 + 8) * K = 16K` unique elements to be loaded.

This highlights the need to use dedicated logic to compute work group sizes for matrix multiplication shaders.

## Changes

* Introduce `pick_hw_square_wg_size`
* Use the new local work group size determination function for Quantized Linear, Matmul, and Linear

Subject: [PATCH 217/423] [ET-VK] Add mechanism to trigger command buffer
 re-encode only when necessary (#13379)

## Context

Dynamic shape models currently will require the command buffer to be re-encoded every inference. However, this introduces a significant overhead when running models that require dynamic shapes.

The reality is that a command buffer  re-encode may not be needed every frame. A command buffer re-encode will only be needed when:

1. Shader dispatch parameters change; i.e. new tensor sizes require a completely different compute shader, require new local work group sizing, or require new work group grid size (i.e. global work group size / local work group size)
2. Push constants containing tensor metadata need to be updated

This diff aims to reduce the overhead of triggering tensor shape change by detecting when a command buffer re-encode is actually needed.

## Changes

`ComputeGraph`:
* Introduce `requires_reencode` flag to `ComputeGraph` to indicate when a command buffer re-encode is needed.
* Introduce a `std::set<ValueRef>` tracking which values were updated when propagating tensor sizes
  * "update" can be one of two things: 1) tensor sizes changed 2) symint value changed

`DispatchNode`:
* When propagating new tensor sizes, only execute the resize function if any of the values participating in the computation have been updated
* Mark `requries_reencode` if any push constants associated with tensor metadata need to be udpated

`DynamicDispatchNode`:
* Only recompute compute shader dispatch params if any of the values participating in the computation have been updated
* Mark `requires_reencode` if 1) a new compute shader is required, 2) local work group size changed, 3) work group grid size changed

Subject: [PATCH 219/423] [Backend Tester] Clean up a few test issues (#13258)

There are a few broken tests that need cleaning up. Some are failing due
to missing portable kernels. These tests are now skipped if any
unsupported portable ops remain post-delegation. I also fixed a few
other small issues and bumped the element-wise tolerance to reduce false
positives. SNR should hopefully catch most blatant correctness issues.
The fp16 and quantized tests can generate occasional high element-wise
error but still have decent SNR (~60+).

Subject: [PATCH 220/423] [Backend Tester] Clean up report output (#13306)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update the report output to be a bit cleaner. I've made the following
changes:
 * Round decimal values to 3 decimal places.
* Remove mean signed deviation and L2 norm. We have SNR, mean absolute
error, and max element-wise error. I think that's sufficient.
* Rename SQNR to SNR. Not all tests are quantized and we're using it as
a general measure of tensor-wise error.
* Split out the result column into pass/skip/fail and a detailed reason.
This should be easier to parse at a glance.

Example output (not sure markdown formatting is weird here...):

Test ID | Test Case | Flow | Params | Result | Result Detail | Delegated
| Quantize Time (s) | Lower Time (s) | Delegated Nodes | Undelegated
Nodes | Delegated Ops | Undelegated Ops | PTE Size (Kb) | Output 0 Error
Max | Output 0 Error MAE | Output 0 SNR | Output 1 Error Max | Output 1
Error MAE | Output 1 SNR

Subject: [PATCH 221/423] [Backend Tester] Write report progressively (#13308)

Append to the report file line by line after each test, rather than all
at the end. This ensures that report data is available if the test run
is aborted or hit with an unrecoverable native crash.

Subject: [PATCH 222/423] create and validate build_variables.bzl (#8326)

First step of #8268 -- we are moving from buck-extracted filelist to
using one shared filelist, and the first step is to create the shared
filelist and validate it against the buck generation.

+# WARNING: the contents of this file must BOTH be valid Starlark (for Buck) as well as

+# (as they are not recognized by Python). If you want to fix this, figure out how run
+# this file from cmake with a proper Starlark interpreter as part of the default OSS
+# build process. If you need some nontrivial Starlark features, make a separate bzl
+# file. (Remember that bzl files are not exported via ShipIt by default, so you may also
+# need to update ExecuTorch's ShipIt config.)

+# This file contains srcs lists that are shared between our Buck and CMake build
+# systems. We had three choices for listing src files:
+# 1) List them in Buck and use buck query to get them in CMake. This was our setup for a
+# long time; the problem is that OSS users would prefer not to have to deal with Buck at
+# all.
+# 2) List them in both Buck targets.bzl files and CMake's CMakeLists.txt files. This is
+# unnecessary duplication, and people will invariably forget to update one or the other.
+# 3) List them somewhere CMake and Buck can both get at them; that's this file. Buck
+# files can load() it, and our CMake build evaluates it with Python. (See
+# executorch_append_filelist in build/Codegen.cmake.)
+#
+# Inconveniently, the Buck target layout is much more granular than the CMake library
+# layout, leading to several complications:
+# 1) Single-file Buck targets will just list the one src file they contain. Nothing to
+# share with CMake in that case, and that src will be in a list in this file that does
+# not map directly to that particular Buck target.
+# 2) Multi-file Buck targets should have a list below that corresponds exactly to their
+# `srcs`. There should then be simple Python code that combines those lists into lists
+# that map 1:1 to the CMake library layout.

Subject: [PATCH 224/423] [Backend Tester] Reduce log verbosity / spam (#13312)

When running tests, deprecation warnings for export_for_training and
"internal consistency verification was requested but not available"
create a large amount of spam in the CLI and drown out actual test info
during the run. Neither warning is particularly useful. I've suppressed
the the export_for_training warning in the backend tester only and
switched the tester to not request internal consistency verification
since it's not compiled into pybindings by default. This gives much
cleaner CLI output.

Before:
```

Subject: [PATCH 227/423] Qualcomm AI Engine Direct - Static Decoder Runner
 Support 16bit KV IO (#13127)

### Summary

- Support 16bit KV IO for runner. (Capable to run either 8bit or 16bit)
- Adding README for script to run Qwen2.5 0.5B
- Improving the PPL score for Qwen2.5 0.5B from 18->12.
- Fixing BC CI bug.

Sample Script
`python examples/qualcomm/oss_scripts/llama/llama.py -b build-android -s
$DEVICE -m SM8750 --prompt "What is 1+1?" --temperature 0 --model_mode
kv --max_seq_len 1024 --ptq 16a8w --decoder_model qwen2_5
--eval_perplexity --tasks wikitext --limit 1 --artifact
./16bit_qwen_1024 --enable_masked_softmax --r3`

#### Stats with QNN2.37.0 on SM8750
Accuracy: 12ppl (Align with prepare_pt2e and convert_pt2e)
Token Rate:  ~130tok/sec, depending on seq_len.

Subject: [PATCH 229/423] Bump Zephyr SDK Version in CI Image from v0.16.0 ->
 v0.17.2 (#13380)

### Summary
Previously, the CI docker image that was used for the Zephyr tests
downloaded and used the v0.16.0 version of the Zephyr SDK. Zephyr has
updated their documentation to recommend user to use v0.17.2. This PR
makes the needed change so that the CI job that runs the Zephyr tests
pulls the v0.17.2 version of the SDK.

### Test Plan
Tested on local repro of Docker image, and all support models (`add`,
`softmax`, and `mv2`) still pass.

Subject: [PATCH 230/423] [Backend Tester] Seed based on test name (#13313)

Set a manual seed for pytorch based on the test base name (test case not
including flow / etc.). This makes test results stable between runs and
between backends/flows. This is useful for comparing accuracy between
backends, for example.

I validated this change by running convolution tests for xnnpack twice.
I validated that the output accuracy statistics were identical.

Subject: [PATCH 233/423] Set a doc build variable for executorch version
 (#13351)

### Summary
Now in docs we can use `${executorch_version}` to represent executorch
version.

It's defined in docs/source/executorch_custom_versions.py
`EXECUTORCH_VERSION = "0.7.0"`

### Test plan

In
https://docs-preview.pytorch.org/pytorch/executorch/13351/getting-started.html#id1,
the version is correct:
```
implementation("org.pytorch:executorch-android:0.7.0")
```

Subject: [PATCH 239/423] Arm backend: Generate ETRecord from arm_aot_compiler
 (#13273)

An ETRecord file is generated if ETDump or BundleIO is used. This also
adds tests for --bundleio and --etdump to make sure it works.

Subject: [PATCH 242/423] [Backend Tester] Add test flow CLI arg (#13360)

Add a CLI arg to filter by test flow. We have a backend filter, but this
allows for selecting only a quantized flow, for example.

Verified with the following. Only the (unquantized) CoreML flow was run.
```
python -m executorch.backends.test.suite.runner operators --filter test_add --flow coreml
```

-# ExecuTorch Arm/TOSA Delegate
+# ExecuTorch Arm&reg; Delegate for TOSA devices
 
 This subtree contains the Arm(R) Delegate implementation for ExecuTorch.
 
 This delegate is structured to, over time, support a number of different Arm devices
 through an AoT flow which targets multiple Arm IP using the TOSA standard.
 
-The expected flow is:
- * torch.nn.module -> TOSA -> command_stream for fully AoT flows e.g. embedded.
- * torch.nn.module -> TOSA for flows supporting a JiT compilation step.
-
-Current backend support is being developed for TOSA to Ethos(TM)-U55/65/85 via the
-ethos-u-vela compilation stack. which follows the fully AoT flow.
-
-## Layout
+For more information on TOSA see https://www.mlplatform.org/tosa/tosa_spec.html
+
+**The expected flows are:**
+* torch.nn.module -> TOSA for development and validation of model export
+* torch.nn.module -> TOSA/VGF for flows supporting a JiT compilation step.
+* torch.nn.module -> TOSA -> command_stream for fully AoT flows e.g. embedded.
+
+**Currently device support is for:**
+* TOSA to Ethos&trade;-U55/65/85 via the ethos-u-vela compilation stack.
+  * This is cross-compiled to the appropriate target CPU
+  * There is a separate arm_executor_runner for bare-metal platforms
+* TOSA to VGF via the model-converter for devices supporting the ML SDK for Vulkan&reg;
+  * The VGF graph represents TOSA directly in a SPIR-V&trade; standardized form.
+  * As the VGF delegate runs on Vulkan, it's required to be built with the Vulkan delegate also present.
+
+**Currently supported development platforms are:**
+* For ahead of time tooling
+  * Linux aarch64
+  * Linux x86_64
+  * macOS with Apple silicon
+* Bare metal builds For the Ethos-U target and Cortex-M targets
+  * Full testing is available in tree for the Corstone&trade; FVPs
+  * This is a reference implementation for porting to silicon targets
+* Linux target support For VGF capable targets
+  * This flow re-uses the common executor_runner
+
+## Layout of key components

-There are currently 3 ways we unit test our code.
-1. TOSA main inference. These tests are using non-quantized data and ops. Edge IR representation of the module is lowered to a TOSA flatbuffer, which is tested for numerical correcteness using the ```tosa_reference_model``` tool.
-2. TOSA base inference. Same as above, but data and ops are quantized.
-3. Ethos-U55. These tests use quantized data and ops (aka TOSA base inference). Edge IR is lowered to a TOSA flatbuffer, which is fed into the Vela compiler. Theses tests are functional tests and do not test numerical correctness, since that should be guaranteed by TOSA.

 # Arm Backend Architecture
 
 The broad principle with the Arm backend implemention for ExecuTorch is to support multiple Arm devices and device configurations through a largely Homogeneous flow with maximal sharing of class logic.
-The EthosUBackend is currently the one user facing API that target the Ethos-U55 and Ethos-U85 hardware IP. It is using the TOSABackend under the hood to share code and functionality, but also to separate testing possibilities to the TOSA flow itself.
+The EthosUBackend and VgfBackend are the user facing targets available for the the Ethos-U55 and Ethos-U85 hardware IP, and VGF targets. It is using the TOSABackend under the hood to share compiler passes and legalisation, along with other code and functionality, but also to enable separate testing for the TOSA flow itself.
 
 In practice for compilation, this means that the flow goes via [Arm TOSA](https://www.mlplatform.org/tosa/tosa_spec.html) to produce a common IR and quantization behaviour compatible with our various IP, and typically, device-specific backends to further lower to a device specific binary which can happen ahead of time (within the Python development flow) or at runtime (during a JIT compilation stage).
 
-In practice for the runtime, this means we will share common runtime backend functionality, with the aim for features like debugging to be available through common tooling.

 ## Arm Backend Status and Maturity
 
-The Arm EthosU Backend should be considered a prototype quality at this point, likely subject to significant change and improvement, and with a limited coverage of functionality. We are actively developing this codebase.
+The Arm EthosU Backend should be considered reasonable quality at this point, supporting a large number of operators and major networks.
+The Arm VGF Backend should be considered of Alpha quality, likely subject to significant change and improvement, and with a limited coverage of functionality.
+We are actively developing the codebase for both targets.
 
 ## Current flows
 
-The EthosUBackend has a two stage process,
-- Compile to TOSA to rationalise the graph into known hardware support profiles. Currently this is to v1.0 TOSA INT with specific concern to a subset which gives support on Ethos-U55 and Ethos-U85, the target of the initial prototype efforts. This calls into the TOSABackend.
-- Lower via the ethos-u-vela compilation flow which takes TOSA v1.0 as an input and produces a low level commandstream for the hardware which is then passed via the delegate to the ethos-u-core-driver for direct execution.
+The Arm backends have a two stage process,
+1. Compile to TOSA to by applying FX passes and legalizing the graph into supported TOSA profiles. Currently this is to v1.0 TOSA INT/FP, this is via calls into the TOSABackend.
+1. Lower via the target compilation flow which takes TOSA v1.0 as an input and produces a lower level format for the hardware
+  * For Ethos-U this is a hardware command stream that is possible to directly execute on hardware
+  * For VGF this is a SPIR-V representation of TOSA to enable JiT compilation on the target platform
 
-The EthosUPartitioner is currenly used to ensure the operations converted are Ethos-U compatible, but will be extended to offer spec-correct TOSA Base inference and TOSA Main Inference generation in future.
+All targets provide a partitioner to enable the standard partially delegated flow offered by ExecuTorch.
 
-There is also a generic TOSABackend with accompanying TOSAPartitioner and TOSAQuantizer, which are used by the EthosUBackend and friends. The Arm TOSA Backend can be used by it's own to verify the lowering to the TOSA representation of the model (refer to the unit tests in backends/arm/test which uses the TOSA backend in the test suites).
+There is also a generic TOSABackend with accompanying TOSAPartitioner and TOSAQuantizer, these can be used directly to verify the lowering to the TOSA representation of the model (refer to the unit tests in backends/arm/test which uses the TOSA backend in the test suites).
 
 ### Controlling compilation
 
 It is possible to control the compilation flow to aid in development and debug of both networks and the code itself.
 
-Configuration of the EthosUBackend export flow is controlled by CompileSpec information (essentially used as compilation flags) to determine which of these outputs is produced. In particular this allows for use of the tosa_reference_model to run intermediate output to check for correctness and quantization accuracy without a full loop via hardware implemntation.
-
-As this is in active development see the EthosUBackend for accurate information on [compilation flags](https://github.com/pytorch/executorch/blob/29f6dc9353e90951ed3fae3c57ae416de0520067/backends/arm/arm_backend.py#L319-L324)
+Configuration of the export flow is controlled by CompileSpec information (essentially used as compilation flags) to determine which of these outputs is produced. In particular this allows for compilation flags, capturing intermediate forms during lowering, and use of the tosa_reference_model to run intermediate output to check for correctness and quantization accuracy without a full loop via hardware implemntation.
 
 ## Model specific and optional passes
 The current TOSA version does not support int64. However, int64 is commonly used in many models. In order to lower the operators with int64 inputs and/or outputs to TOSA, a few passes have been developed to handle the int64-related issues. The main idea behind these passes is to replace the uses of int64 with int32 where feasible.

+### Software
 
-To generate software which can be run on an embedded platform (real or virtual), we will need a tool chain for cross-compilation and an Arm Ethos-U software development kit, including the Vela compiler for Ethos-U NPUs.
+First, you will need to install ExecuTorch. Please follow the recommended tutorials if you haven't already, to set up a working ExecuTorch development environment. For the VGF backend it's recommended you [install from source](https://docs.pytorch.org/executorch/stable/using-executorch-building-from-source.html), or from a [nightly](https://download.pytorch.org/whl/nightly/executorch/).

+It is possible to install both sets of dependencies if you omit the disable options.
 
-Next we will walk through the steps performed by the `setup.sh` script to better understand the development setup.
-
-### Download and Set Up the Corstone-300 and Corstone-320 FVP
 
-Fixed Virtual Platforms (FVPs) are pre-configured, functionally accurate simulations of popular system configurations. Here in this tutorial, we are interested in Corstone-300 and Corstone-320 systems. We can download this from the Arm website.
+### Notes:
 
-```{note}
- By downloading and running the FVP software, you will be agreeing to the FVP [End-user license agreement (EULA)](https://developer.arm.com/downloads/-/arm-ecosystem-fvps/eula).
+```{warning}

-
-### Download and Install the Arm GNU AArch32 Bare-Metal Toolchain
-
-Similar to the FVP, we would also need a tool-chain to cross-compile ExecuTorch runtime, executor-runner bare-metal application, as well as the rest of the bare-metal stack for Cortex-M55/M85 CPU available on the Corstone-300/Corstone-320 platform.
-
-These toolchains are available [here](https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads). We will be using GCC 13.3.rel1 targeting `arm-none-eabi` here for our tutorial. Just like FVP, `setup.sh` script will down the toolchain for you. See `setup_toolchain` function.
-
-### Setup the Arm Ethos-U Software Development
-
-This git repository is the root directory for all Arm Ethos-U software. It is to help us download required repositories and place them in a tree structure. See `setup_ethos_u` function of the setup script for more details.

+## Running on the VGF backend with the standard executor_runner for Linux

+Follow typical [Building ExecuTorch with CMake](using-executorch-building-from-source.md) flow to build the linux target, ensuring that the VGF delegate is enabled.
+
+```bash
+-DEXECUTORCH_BUILD_VGF=ON

 ## Takeaways
 In this tutorial you have learnt how to use the ExecuTorch software to both export a standard model from PyTorch and to run it on the compact and fully functioned ExecuTorch runtime, enabling a smooth path for offloading models from PyTorch to Arm based platforms.

Subject: [PATCH 263/423] Improve optimum coverage in ET (more models, xnnpack
 on mac) (#13400)

### Summary
Improves CI coverage of Optimum in ET:
- More model coverage
- Add XNNPack coverage for mac
- Adds perplexity checks for causal LM tests instead of just printing
output
- Refactors all Optimum CI to use the same testing modules.

### Test plan
Run trunk tests

```

This happens when there are non-placeholder nodes that appear before the
last placeholder nodes in `exported_program.graph.nodes`; in this case
the pass will try to access an input spec outside the bounds of the
graph signature.

## Fix

Instead of tracking the index of the the current node being processed,
track the number of placeholder nodes observed. This will ensure that
the input spec being accessed will match the current placeholder node
being processed.

Subject: [PATCH 268/423] Arm backend: Add missing using-declaration in
 VGFBackend.cpp (#13460)

The PR https://github.com/pytorch/executorch/pull/13004 moved `EValue`
to the `Span` namespace but did not add the corresponding
using-declaration in VGFBackend.cpp.

Adds the missing using-declaration to fix the build.

Subject: [PATCH 280/423] [ET-VK] Move rotary embedding custom op to be handled
 via graph pass instead of source transform (#13465)

## Motivation

Be able to test Vulkan lowering via optimum-executorch.

## Context

Currently, ET-VK implements rotary embeddings via a custom op. This op is currently inserted into Transformer models by replacing Rotary Embedding modules with a custom module that executes the custom op via a source transform.

The source transform approach makes it cumbersome to lower LLMs to Vulkan, since it requires the export logic to apply the source transform before calling `torch.export()`. This in turn makes it difficult to integrate Vulkan lowering into optimum-executorch, which tries to use a common export + lowering logic for all lowering paths.

As an alternative, leverage `SubgraphMatcher` to detect fusable patterns and fuse the rotary embedding graph pattern into the custom op as part of the Vulkan delegate's graph passes. This removes the requirement to apply a custom source transform just for Vulkan.

## Changes

* Introduce the `backends/vulkan/patterns` folder to store fusable graph patterns
* Introduce a fusable graph pattern for rotary positional embeddings
* Update partitioner logic to automatically include nodes that are part of a fusable graph pattern
* Introduce a pass to fuse known patterns into custom ops / custom op sequence

Subject: [PATCH 282/423] [ET-VK] Enable IntxWeightOnlyConfig (#13466)

## Motivation

Be able to test Vulkan lowering via optimum-executorch.

## Context

Very similar to the below PR, Int4 weight only quantization is currently enabled in Vulkan via a custom source transform quantizer that replaces linear layers with a custom linear layer that calls a custom weight only quantized linear op.

This diff aims to make it so that no Vulkan specific source transforms need to be applied by adding a fusion pattern for weight only quantized linear.


## Changes

* Introduce a fusable graph pattern for weight only quantized linear
* Add fusion logic for weight only quantized linear in the fuse patterns pass
* Add `4w` qmode to the export llama script

Subject: [PATCH 283/423] Add aten::_upsample_bilinear2d_aa.out (#13458)

Summary:

Trying to resolve https://github.com/pytorch/executorch/issues/7031

Vibe-coded using the existing non-alias version in ET and Aten
implementation in pytorch as reference, along with reference unittests
in pytorch core

Test Plan:

1. Run
https://gist.github.com/mergennachin/9b02aee4feb5acc83e71d8f902f5cca1
And then call `./cmake-out/executor_runner minicpmv_preprocessor.pte`

2. https://gist.github.com/mergennachin/a24e4509804de99caf906c9b79ea45fc

Subject: [PATCH 288/423] Arm backend: Add example linkerscripts for U55/U85
 (#13404)

Add linkerscripts for exector_runner targeting U55/U85 in examples/arm
instead of using the linkerscripts from core_platform and then applying
patches.

The patches are deleted since they are no longer needed.

-Subject: [PATCH] Move the portable kernels to the BRAM
-
-On the Corstone-300, we have 512KB of ITCM and by default,
-the .text section lives in the ITCM. However, as we build more
-portable kernels, we sometimes overflow and the .text section
-no longer fits in the ITCM. This patch moves the portable kernels
-to the BRAM as we have 1MB of BRAM

+    Decomposes cumsum into a 1D convolution with a kernel of ones.
+
+    For example, the cumsum of an input tensor [1, 1] is [1, 1 + 1] = [1, 2].
+    To decompose this, take the input tensor and pre-padded with len(input)-1 zeros and
+    slided over with a kernel [1,1], of length len(input):
+
+    Input:  [0, 1, 1]
+    Kernel: [1, 1]       = [1]
+               [1, 1]    = [2]
+
+    Since pytorch only supports symmetric padding, in reality the result will have
+    an additional 1 calculated at the end, which leads to an required extra slice op.
+
+    To extend this to higher dimensions, the input is reshaped to [N, C, H, W] with

+       C = 1

From: Yufeng Shi <yufeng.shi@arm.com>
Date: Mon, 18 Aug 2025 13:19:02 +0100
Subject: [PATCH 290/423] Arm backend: Add partial vulkan runtime support for
 VgfPipeline (#13471)

- Add XfailIfNoVKMLEmulationLayer for VGF unit tests
- Introduce run_target_board() to unify FVP and VKML execution paths
- Implement run_vkml_emulation_layer() with NotImplementedError for
output parsing, as the VGF runtime doesn't dump the output tensors in a
usable format at the moment.

Subject: [PATCH 295/423] NXP backend: Improve target support checks. (#13367)

### Summary
Improve target specific checks for operator support on Neutron.

### Test plan
Almost all tests utilize the updated functionality, and some unit-tests
were updated to reflect the new implementation.

Date: Mon, 18 Aug 2025 12:30:51 -0700
Subject: [PATCH 297/423] Switch non-top-level ExecuTorch builds (size test,
 examples, etc.) from executorch_srcs.cmake to build_variables.bzl (#13391)

Had to make some minor fixes for compatibility with non-top-level-build
context.

Subject: [PATCH 301/423] [ET-VK][ez] Move execute node threshold calculation
 from `prepare_pipelines()` to `prepare()` (#13497)

Title says it all; `prepare()` is a more appropriate place for this action than `prepare_pipelines()`.

## Motivation

Fix potential floating point exception (divide-by-zero) during tests.

Some tests don't call `prepare_pipelines()`, which means `execute_threshold_node_count_` is unititialized, causing a divide by zero in execute when trying to modulo with `execute_threshold_node_count_`

Subject: [PATCH 302/423] [ET-VK] Runtime support for NamedDataMap (#13498)

Summary:

Allow VulkanBackend to load constant tensors from the NamedDataMap instead of the constant data section of the delegate blob.

## Motivation

This enables several key results:

* Unblocks delegate retargetability with other backends
* Allows reducing peak memory usage when loading models by freeing constant weight data as it gets moved to the GPU

## Changes

* Allow `TensorRef` to be constructed with a `FreeableBuffer` rvalue
* Add ability to load constant data from `NamedDataMap` in `VulkanBackend.cpp`
* When prepacking, free the constant data pointer once it's been copied to the staging buffer

Test Plan:
CI

Validate results by collecting memory measurements in the next few diffs.

Subject: [PATCH 303/423] [ET-VK][AOT] Serialize constant tensors via
 NamedDataMap (#13499)

Summary:
When exporting models to Vulkan backend, save constant tensors in the NamedDataMap instead of the constant data section of the delegate header.

## Motivation

Prevent screen blackout (Llama 3.2 1B) / device crash (Llama 3.2 3B) when running Llama 3.2 models on Samsung Galaxy S24. This behaviour is related to high peak memory usage when loading the model. For more information, see the top diff/PR in the stack.

## Context

This change is based on the equivalent change D70315207/#9153 in XNNPACK.

Test Plan:


## Memory Comparison with/without NamedDataMap

Measured VmRss using

```
uint64_t getVmRssInKB() {
  std::ifstream statusFile("/proc/self/status");
  std::string l, num;
  while (std::getline(statusFile, l)) {
    if (l.substr(0, 5) == "VmRSS") {
      size_t pos = l.find_first_of("0123456789");
      num = l.substr(pos);
      break;
    }
  }
  uint64_t vmRssInKB = std::stoi(num);
  return vmRssInKB;
}
```

Subject: [PATCH 304/423] [ET-VK] Allocate memory for weight and activation
 tensors lazily (#13501)

Summary:
* Allocate memory for weight tensors right before the prepacking shader is dispatched, rather than while building the graph
* Move allocation of shared objects (i.e. memory for intermediate tensors) to occur after prepacking

## Motivation

Prevent screen blackout (Llama 3.2 1B) / device crash (Llama 3.2 3B) when running Llama 3.2 models on Samsung Galaxy S24. This behaviour is related to high peak memory usage when loading the model.

## Full Context

During model loading, Vulkan delegate needs to store 3 copies of constant data in memory at various points:

* source data obtained from loading the model
* staging buffer
* GPU texture/buffer

The general rationale of this change is to allocate memory for each copy only when necessary to minimize the "overlap" when all 3 exist at once.

### Current Order of operations

Legend:
* `W` represents total weight nbytes
* `w` represents weight nbytes for one tensor
* `A` represents total activations nbytes
* `M` represents approximation of total memory footprint

First, model file is loaded

Then, when building compute graph, for each weight tensor:
1. Weight data is loaded from NamedDataMap (`M = W`)
2. GPU texture/buffer for weight is initialized + memory allocated (`M = 2W`)
3. After building the graph, `graph->prepare()` is called which currently allocates memory for the activation tensors as well (`M = 2W + A`)

Then, during the prepacking stage for each weight tensor, each weight tensor is copied individually:
1. Staging buffer initialized (`M = 2W + A + w`)
2. Copy CPU weight data to staging + CPU Weight data is freed (`M = 2W + A`)
3. Compute shader dispatch to copy staging to GPU texture/buffer + free staging buffer (`M = 2W + A - w`)

The peak usage in mainline will be `M = 2W + A + w`

### Revised order of operations

This change revises the order of operations:

1. Weight data is loaded from NamedDataMap (`M = W`)
2. GPU texture/buffer for weight is initialized, but **memory is not allocated** (`M = W`)

Then, during the prepacking stage for each weight tensor, each weight tensor is copied individually:
1. Staging buffer initialized (`M = W + w`)
2. **Memory allocated for GPU texture/buffer** (`M = W + 2w`)
3. Copy CPU weight data to staging + CPU Weight data is freed (`M = W + w`)
4. Compute shader dispatch to copy staging to GPU texture/buffer + free staging buffer (`M = W`)

**Then, after all prepacking operations complete, only then is Activation memory allocated** (`M = W + A`)

Under this scheme, peak memory is reduced to `M = W + A` (or alternatively `M = W + 2w` if `2w > A`) which is (or at least very close to) the theoretical minimum.

Test Plan:
## Logging Memory Usage

Using

```
uint64_t getVmRssInKB() {
  std::ifstream statusFile("/proc/self/status");
  std::string l, num;
  while (std::getline(statusFile, l)) {
    if (l.substr(0, 5) == "VmRSS") {
      size_t pos = l.find_first_of("0123456789");
      num = l.substr(pos);
      break;
    }
  }
  uint64_t vmRssInKB = std::stoi(num);
  return vmRssInKB;
}

uint64_t getVmaStatsInKB() {
  auto stats =
      vkcompute::api::context()->adapter_ptr()->vma().get_memory_statistics();
  uint64_t vmaBlockInKB = stats.total.statistics.blockBytes >> 10;
  return vmaBlockInKB;
}
```

to log memory footprint at various points of inference when running the llama_runner binary with Llama 3.2 1B, we can compare the memory footprint with and without these changes.

Memory usage at end of execute: 1363636 KB (VmRSS), 2330528 KB (VMA)
```

It is evident how peak memory can be reduced with these changes, as VMA footprint gradually increases while loading the model while VmRss gradually decreases. Without these changes, VMA footprint will reach its peak after initializing the graph.

Visually, it can also be verified that Samsung Galaxy S24's screen no longer blacks out while loading the model.

Subject: [PATCH 308/423] Stop validating that build_variables.bzl matches
 buck-generated executorch_srcs.cmake (#13392)

The previous PR switched to build_variables.bzl as the source of truth.
We can land this PR when we are happy to stop requiring Buck.

Subject: [PATCH 310/423] Stop looking for buck2 in the top-level ExecuTorch
 build (#13393)

We should no longer require buck for the main build. (Note that
scripts/build_apple_frameworks.sh still requires it for a custom script,
and the following PR will attempt to clean up mentions of BUCK2 from
scripts.)

Subject: [PATCH 312/423] Add a generic multimodal runner (#13166)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
This diff adds a generic multimodal runner for Executorch. It includes
changes to the `image_prefiller.h` file, which adds a `prefill` method
that takes an `Image` object and returns the next token of the LLM
module after prefill. It also includes changes to the
`multimodal_runner.cpp` file, which implements the `MultimodalRunner`
class for multimodal input and text output LLMs. The `MultimodalRunner`
class uses the `ImagePrefiller`, `TextPrefiller` classes to prefill the
KV cache of the model, then uses `TextTokenGenerator` to run the
autoregressive generation loop.

See diagram:

+# LLM Runner Framework for ExecutorTorch
+
+This directory contains the LLM Runner framework for ExecutorTorch, providing high-level C++ APIs for running Large Language Models with both text-only and multimodal capabilities.
+
+## Overview
+
+The LLM Runner framework provides two main runner classes:
+
+- **TextLLMRunner**: For text-only language models (e.g., Llama, GPT, etc.)
+- **MultimodalRunner**: For multimodal models that can process text, images, and audio (e.g., LLaVA, CLIP-based models)
+
+Both runners are built on a modular architecture with dependency injection, providing clean separation of concerns and efficient resource management.
+
+## Architecture Overview
+
+## MultimodalRunner Architecture
+
+The MultimodalRunner supports mixed inputs (text, images, audio) and generates text outputs:

+
+int main() {
+    // Load tokenizer and create runner
+    auto tokenizer = load_tokenizer("tokenizer.bin");
+    auto runner = create_text_llm_runner("model.pte", std::move(tokenizer));
+
+    // Configure generation
+    GenerationConfig config;
+    config.max_new_tokens = 100;
+    config.temperature = 0.7f;
+    config.echo = true;
+
+    // Set up callbacks
+    auto token_callback = [](const std::string& token) {
+        std::cout << token << std::flush;
+    };
+
+    // Generate text
+    auto error = runner->generate(
+        "Hello, how are you?",  // prompt
+        config,                 // configuration
+        token_callback         // token callback
+    );
+
+    return error == executorch::runtime::Error::Ok ? 0 : 1;
+}

+
+    // Create multimodal inputs
+    std::vector<MultimodalInput> inputs;
+    inputs.emplace_back(make_text_input("What do you see in this image?"));
+
+    // Load and add image
+    Image image = load_image("photo.jpg");  // Your image loading function
+    inputs.emplace_back(make_image_input(std::move(image)));
+
+    // Configure generation
+    GenerationConfig config;
+    config.max_new_tokens = 150;
+    config.temperature = 0.7f;
+    config.echo = true;
+
+    // Set up callbacks
+    auto token_callback = [](const std::string& token) {

+
+    auto stats_callback = [](const Stats& stats) {
+        std::cout << "\nGenerated " << stats.num_generated_tokens << " tokens" << std::endl;
+    };
+
+    // Generate text

+
+## Helper Functions
+
+The framework provides utility functions in `llm_runner_helper.h`:
+
+### load_tokenizer()
+```cpp
+std::unique_ptr<tokenizers::Tokenizer> load_tokenizer(
+    const std::string& tokenizer_path,
+    std::unique_ptr<std::vector<std::string>> special_tokens = nullptr,
+    std::optional<std::string> pattern = std::nullopt,
+    size_t bos_token_index = 0,
+    size_t eos_token_index = 1
+);
+```
+
+### create_text_llm_runner()
+```cpp
+std::unique_ptr<TextLLMRunner> create_text_llm_runner(
+    const std::string& model_path,
+    std::unique_ptr<::tokenizers::Tokenizer> tokenizer,
+    std::optional<const std::string> data_path = std::nullopt,
+    float temperature = -1.0f
+);
+```
+
+### create_multimodal_runner()
+```cpp
+std::unique_ptr<MultimodalRunner> create_multimodal_runner(
+    const std::string& model_path,
+    std::unique_ptr<::tokenizers::Tokenizer> tokenizer,
+    std::optional<const std::string> data_path = std::nullopt,
+    float temperature = 0.8f
+);
+```
+
+### get_llm_metadata()
+```cpp
+std::unordered_map<std::string, int64_t> get_llm_metadata(
+    tokenizers::Tokenizer* tokenizer,
+    Module* module
+);
+```
+
+## Configuration and Tuning
+
+### Generation Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `max_new_tokens` | `int32_t` | `-1` | Maximum new tokens to generate (-1 = use available context) |
+| `seq_len` | `int32_t` | `1024` | Total sequence length including prompt |
+| `temperature` | `float` | `0.8f` | Sampling temperature (0.0 = deterministic, 1.0+ = creative) |
+| `echo` | `bool` | `true` | Whether to echo the input prompt |
+| `num_bos` | `int8_t` | `1` | Number of beginning-of-sequence tokens |
+| `num_eos` | `int8_t` | `1` | Number of end-of-sequence tokens |
+| `warming` | `bool` | `false` | Whether this is a warmup run |
+
+### Performance Tuning
+
+**Memory Optimization**:
+- Use KV cache for efficient autoregressive generation
+- Enable parallel prefill for faster prompt processing
+- Set appropriate `seq_len` based on available memory
+
+**Sampling Strategies**:
+- Low temperature (0.1-0.3) for factual, deterministic output
+- High temperature (0.7-1.0) for creative, diverse output
+- Set `max_new_tokens` to prevent runaway generation
+
+**Monitoring**:
+```cpp
+auto stats_callback = [](const Stats& stats) {
+    std::cout << "Model load time: "
+              << (stats.model_load_end_ms - stats.model_load_start_ms) << "ms" << std::endl;
+    std::cout << "Inference time: "
+              << (stats.inference_end_ms - stats.inference_start_ms) << "ms" << std::endl;
+    std::cout << "Tokens/second: " << stats.tokens_per_second() << std::endl;
+};
+```
+
+## Supported Models
+
+### TextLLMRunner
+- **Llama family**: Llama 2, Llama 3, Code Llama
+- **GPT models**: GPT-2, GPT-3.5, GPT-4 (compatible architectures)
+- **Phi models**: Phi-3-mini and variants
+- **Custom models**: Any transformer-based text generation model
+
+### MultimodalRunner
+
+**Note**: The MultimodalRunner currently supports **EarlyFusion** model architectures only. EarlyFusion is a type of fused model architecture where pretrained encoder(s) are combined with a pretrained decoder (LLM) at the model input and not in internal layers. This is a popular architecture for multimodal models, with a full overview available in [The Evolution of Multimodal Model Architectures](https://arxiv.org/abs/2405.17927). This module works both for decoders in which the encoder tokens are inside the vocab and outside the vocab.
+
+**Supported EarlyFusion Models**:
+- **LLaVA**: Large Language and Vision Assistant
+- **CLIP-based models**: Contrastive Language-Image Pre-training
+- **Gemma3 4B**: Multimodal variant with vision capabilities
+- **Voxtral**: Audio-text multimodal models
+- **Custom EarlyFusion models**: Any model with separate encoders that fuse at the input level
+
+**DeepFusion Models (Not Currently Supported)**:
+DeepFusion is another popular model architecture type where a pretrained encoder is combined with a pretrained decoder (LLM) in the internal decoder layers. A common deep fusion architecture is to fuse the encoder input into the decoder with interspersed cross-attention layers. DeepFusion models are currently out of scope because they require significant model definition rewrites to work with torch.export.
+
+**Examples of DeepFusion models (not supported)**:
+- **Llama 3.2 Vision**: Uses cross-attention layers for vision-text fusion
+- **Other cross-attention based multimodal models**
+
+For DeepFusion support, consider using the model's native inference framework or wait for future ExecutorTorch updates that may include DeepFusion architecture support.

+ * MultimodalRunner - A runner for multimodal input and text output LLMs
+ *
+ * This class is designed for Large Language Models that can process multimodal
+ * inputs (text, images, audio) and generate text outputs. It supports models
+ * like LLaVA, CLIP-based vision-language models, and speech-to-text models.
+ *
+ * Supported Model Architecture see README.md
+ *
+ * Key Features:
+ * - Supports mixed multimodal inputs in any order via
+ * std::vector<MultimodalInput>
+ * - Encoder handles non-text modalities (images, audio) → embeddings
+ * - Text tokenizer converts text tokens → embeddings
+ * - Embeddings are stitched together based on input ordering
+ * - Text decoder performs autoregressive generation with KV cache
+ * - Internal pos_ state tracks KV cache position across calls
+ * - GenerationConfig provides comprehensive control over generation parameters
+ *
+ * Usage:
+ *   std::vector<MultimodalInput> inputs;
+ *   inputs.emplace_back(make_text_input("Describe this image:"));
+ *   inputs.emplace_back(make_image_input(std::move(image)));
+ *
+ *   GenerationConfig config;
+ *   config.max_new_tokens = 100;
+ *   config.temperature = 0.7f;
+ *
+ *   runner->generate(inputs, config, token_callback, stats_callback);

Subject: [PATCH 317/423] Wrap LLM runner tests in anonymous namespace (unbreak
 unittest-release) (#13524)

This prevents our test classes from colliding with other
global-namespace classes. The specific cause was MockModule being
(apparently) the name of a class in gmock or gtest, but I went ahead and
did all the tests in this directory to be safe.

-"""Extracts source lists from the buck2 build system and writes them to a file.
-
-The config file is in TOML format and should contains one or more
-`[targets.<target-name>]` entries, along with an optional `[target_base]` entry.
-
-All of these may have the following lists of strings:
-- buck_targets: The list of buck targets that map to `<target-name>`.
-- deps: A list of other `<target-name>` entries that this target depends on.
-  Used to prune sources that are provided by those other targets.
-- filters: A list of regular expressions. This tool will only emit source files
-  whose relative paths match all entries.
-- excludes: A list of regular expressions. This tool will not emit source files
-  whose relative paths match any entry.
-
-The special `[target_base]` entry provides default lists that are inherited by
-the `[target.<target-name>]` entries. When the `[target.<target-name>]` entry defines
-a key that is already present in `[target_base]`, the target-specific entries are
-appended to the base list.

Subject: [PATCH 319/423] [Backend Tester] Add nightly CI job for XNNPACK
 (#13390)

Set up a nightly CI job to run the backend model and operator tests for
xnnpack (unquantized and static int8 per channel). This is the first
step in setting up continuous coverage using the new suite. I've chosen
nightly as the initial run cadence as some of the larger test suites are
very long. In the medium-term, I'd like to run a subset of these tests
on pull or trunk, but we can start with this.

Subject: [PATCH 320/423] Add Model Profiling Automation Script (#13493)

### Summary
Added profile_model.sh to automate the ExecutorTorch model profiling
workflow. The script streamlines building executor_runner with profiling
enabled, running model inference with ETDump collection, and generating
CSV profiling reports. It accepts model and ETDump paths as arguments
with sensible defaults, consolidating what was previously a multi-step
manual process into a single executable script.

### Test plan
Manually ran script on llama3.pte and confirmed csv and dump generation

Subject: [PATCH 327/423] Remove other extensions' source files from
 EXTENSION_TRAINING_SRCS and TRAIN_XOR_SRCS (#13433)

Looks like this was an artifact of improperly specified deps in (now
deleted) cmake_deps.toml. extension/training/CMakeLists.txt already has
the relevant dependencies, so we should be able to just remove these.

Subject: [PATCH 329/423] Qualcomm AI Engine Direct - Remove input_list
 dependencies (#13411)

### Summary
- Current SimpleADB push logic require each script to prepare
input_list, and the name must follow the logic. Remove all these
dependencies.

### Test plan
All existing unit tests should already cover this change.

Subject: [PATCH 331/423] Remove pinning to ET commit for Zephyr CI job 
 (#13388)

### Summary
Currently, the CI jobs responsible for running the Zephyr tests checkout
a past version of ExecuTorch, but runs install_executorch.sh with the
pinned pytorch commit. Ideally, we would resolve this with resolving the
cmake errors that arise from using the most up-to-date version of
executorch, but for now, we can just keep the ExecuTorch and PyTorch
checkouts consistent for CI. This should prevent the Zephyr CI tests
from failing spuriously on unrelated PRs.

### Test plan
[PLEASE REMOVE] How did you test this PR? Please write down any manual
commands you used and note down tests that you have written if
applicable.

Subject: [PATCH 334/423] Fix Olmo trunk test and skip XNNPack trunk tests on
 mac (#13528)

Unblock trunk to advance `viable/strict`

Intermittent segmentation faults on all of the XNNPack Optimum mac
tests. Described in more detail
[here](https://github.com/pytorch/executorch/pull/13530) where the
segmentation fault happens consistently, but interestingly enough this
is before the pin bump and it is only happening intermittently.

Subject: [PATCH 337/423] Arm backend: Remove get_output_nodes from
 runner_utils. (#13417)

A graph has only one output node containing a list of output tensors.
Remove the use of this function to better reflect this.

-## ExecuTorch on ARM Cortex-M55 + Ethos-U55
+## ExecuTorch for Arm backends Ethos-U, VGF and Cortex-M
 
-This dir contains scripts to help you prepare setup needed to run a PyTorch
-model on an ARM Corstone-300 platform via ExecuTorch. Corstone-300 platform
-contains the Cortex-M55 CPU and Ethos-U55 NPU.
+This project contains scripts to help you setup and run a PyTorch
+model on a Arm backend via ExecuTorch. This backend supports Ethos-U and VGF as 
+targets (using TOSA) but you can also use the Ethos-U example runner as an example
+on Cortex-M if you do not delegate the model.
+
+The main scripts are `setup.sh`, `run.sh` and `aot_arm_compiler.py`.
+
+`setup.sh` will install the needed tools and with --root-dir <FOLDER> 
+you can change the path to a scratch folder where it will download and generate build
+artifacts. If supplied, you must also supply the same folder to run.sh with
+--scratch-dir=<FOLDER> If not supplied both script will use examples/arm/ethos-u-scratch
+
+`run.sh` can be used to build, run and test a model in an easy way and it will call cmake for you
+and in cases you want to run a simulator it will start it also. The script will call `aot_arm_compiler.py`
+to convert a model and include it in the build/run.
+
+Build and test artifacts are by default placed under the folder arm_test folder
+this can be changed with --et_build_root=<FOLDER>
+
+`aot_arm_compiler.py` is used to convert a Python model or a saved .pt model to a PTE file and is used by `run.sh`
+and other test script but can also be used directly.
+
+If you prefer to use the ExecuTorch API, there is also the `ethos_u_minimal_example.ipynb` notebook example.
+This shows the workflow if you prefer to integrate a python torch.export and ExecuTorch flow directly into your
+model codebase. This is particularly useful if you want to perform more complex training, such as quantization
+aware training using the ArmQuantizer.
+
+## Create a PTE file for Arm backends
+
+There is an easy to use example flow to compile your PyTorch model to a PTE file for the Arm backend called `aot_arm_compiler.py`
+that you can use to generate PTE files, it can generate PTE files for the supported targets `-t` or even non delegated (Cortex-M)
+using different memory modes and can both use a python file as input or just use the models from examples/models with `--model_input`.
+It also supports generating Devtools artifacts like BundleIO BPTE files, and ETRecords. Run it with `--help` to check its capabilities.
+
+You point out the model to convert with `--model_name=<MODELNAME/FILE>` It supports running a model from examples/models or models
+from a python file if you just specify `ModelUnderTest` and `ModelInput` in it.
+
+```
+$ python3 -m examples.arm.aot_arm_compiler --help
+```
+
+This is how you generate a BundleIO BPTE of a simple add example
+
+```
+$ python3 -m examples.arm.aot_arm_compiler --model_name=examples/arm/example_modules/add.py --target=ethos-u55-128 --bundleio
+```
+
+The example model used has added two extra variables that is picked up to make this work.
+
+`ModelUnderTest` should be a `torch.nn.module` instance.
+
+`ModelInputs` should be a tuple of inputs to the forward function.
+
+
+You can also use the models from example/models directly by just using the short name e.g.
+
+```
+$ python3 -m examples.arm.aot_arm_compiler --model_name=mv2 --target=ethos-u55-64
+```
+
+
+The `aot_arm_compiler.py` is called from the scripts below so you don't need to, but it can be useful to do by hand in some cases.
+
+
+## ExecuTorch on Arm Ethos-U55/U65 and U85
+
+This example code will help you get going with the Corstone&trade;-300/320 platforms and
+run on the FVP and can be used a a starting guide in your porting to your board/HW
 
 We will start from a PyTorch model in python, export it, convert it to a `.pte`
 file - A binary format adopted by ExecuTorch. Then we will take the `.pte`
 model file and embed that with a baremetal application executor_runner. We will
 then take the executor_runner file, which contains not only the `.pte` binary but
 also necessary software components to run standalone on a baremetal system.
-Lastly, we will run the executor_runner binary on a Corstone-300 FVP Simulator
-platform.
+The build flow will pick up the non delegated ops from the generated PTE file and 
+add CPU implementation of them. 
+Lastly, we will run the executor_runner binary on a Corstone&trade;-300/320 FVP Simulator platform.
+
 
 ### Example workflow
 
-There are two main scripts, setup.sh and run.sh. Each takes one optional,
-positional argument. It is a path to a scratch dir to download and generate
-build artifacts. If supplied, the same argument must be supplied to both the scripts.
+Below is example workflow to build an application for Ethos-U55/85. The script below requires an internet connection:
 
-To run these scripts. On a Linux system, in a terminal, with a working internet connection,
 ```
 # Step [1] - setup necessary tools
 $ cd <EXECUTORCH-ROOT-FOLDER>
-$ executorch/examples/arm/setup.sh --i-agree-to-the-contained-eula [optional-scratch-dir]
+$ ./examples/arm/setup.sh --i-agree-to-the-contained-eula
+
+# Step [2] - Setup path to tools, The `setup.sh` script has generated a script that you need to source every time you restart you shell.
+$ source  examples/arm/ethos-u-scratch/setup_path.sh
+
+# Step [3] - build and run ExecuTorch and executor_runner baremetal example application
+# on a Corstone(TM)-320 FVP to run a simple PyTorch model from a file.
+$ ./examples/arm/run.sh --model_name=examples/arm/example_modules/add.py --target=ethos-u85-128
+```
+
+The argument `--model_name=<MODEL>` is passed to `aot_arm_compiler.py` so you can use it in the same way
+e.g. you can also use the models from example/models directly in the same way as above.
+
+```
+$ ./examples/arm/run.sh --model_name=mv2 --target=ethos-u55-64
+```
+
+The runner will by default set all inputs to "1" and you are supposed to add/change the code
+handling the input for your hardware target to give the model proper input, maybe from your camera
+or mic hardware.
+
+While testing you can use the --bundleio flag to use the input from the python model file and
+generate a .bpte instead of a .pte file. This will embed the input example data and reference output
+in the bpte file/data, which is used to verify the model's output. You can also use --etdump to generate
+an ETRecord and a ETDump trace files from your target (they are printed as base64 strings in the serial log).
 
-# Step [2] - Setup Patch to tools, The `setup.sh` script has generated a script that you need to source everytime you restart you shell. 
-$ source  executorch/examples/arm/ethos-u-scratch/setup_path.sh
+Just keep in mind that CPU cycles are NOT accurate on the FVP simulator and it can not be used for
+performance measurements, so you need to run on FPGA or actual ASIC to get good results from --etdump.
+As a note the printed NPU cycle numbers are still usable and closer to real values if the timing
+adaptor is setup correctly.
 
-# Step [3] - build + run ExecuTorch and executor_runner baremetal application
-# suited for Corstone FVP's to run a simple PyTorch model.
-$ executorch/examples/arm/run.sh --model_name=mv2 --target=ethos-u85-128 [--scratch-dir=same-optional-scratch-dir-as-before]
 ```
+# Build + run with BundleIO and ETDump
+$ ./examples/arm/run.sh --model_name=lstm --target=ethos-u85-128 --bundleio --etdump
+```

+## ExecuTorch on ARM Cortex-M
+
+For Cortex-M you run the script without delegating e.g `--no_delegate` as the build flow already supports picking up
+the non delegated ops from the generated PTE file and add CPU implementation of them this will work out of the box in
+most cases.

-   * - Inf and NaN values in the inputs should become Inf and NaN values after
-   * conversion to the single-precision number. Therefore, if the biased
-   * exponent of the half-precision input was 0x1F (max possible value), the
-   * biased exponent of the single-precision output must be 0xFF (max possible
-   * value). We do this correction in two steps:
-   *   - First, we adjust the exponent by (0xFF - 0x1F) = 0xE0 (see exp_offset
-   * below) rather than by 0x70 suggested by the difference in the exponent bias
-   * (see above).
-   *   - Then we multiply the single-precision result of exponent adjustment by
-   * 2**(-112) to reverse the effect of exponent adjustment by 0xE0 less the
-   * necessary exponent adjustment by 0x70 due to difference in exponent bias.
-   *     The floating-point multiplication hardware would ensure than Inf and
-   * NaN would retain their value on at least partially IEEE754-compliant
-   * implementations.
-   *
-   * Note that the above operations do not handle denormal inputs (where biased
-   * exponent == 0). However, they also do not operate on denormal inputs, and
-   * do not produce denormal results.

-
-// c10::complex is an implementation of complex numbers that aims
-// to work on all devices supported by PyTorch
-//
-// Most of the APIs duplicates std::complex
-// Reference: https://en.cppreference.com/w/cpp/numeric/complex
-//
-// [NOTE: Complex Operator Unification]
-// Operators currently use a mix of std::complex, thrust::complex, and
-// c10::complex internally. The end state is that all operators will use
-// c10::complex internally.  Until then, there may be some hacks to support all
-// variants.
-//
-//
-// [Note on Constructors]
-//
-// The APIs of constructors are mostly copied from C++ standard:
-//   https://en.cppreference.com/w/cpp/numeric/complex/complex
-//
-// Since C++14, all constructors are constexpr in std::complex
-//
-// There are three types of constructors:
-// - initializing from real and imag:
-//     `constexpr complex( const T& re = T(), const T& im = T() );`
-// - implicitly-declared copy constructor
-// - converting constructors
-//
-// Converting constructors:
-// - std::complex defines converting constructor between float/double/long
-// double,
-//   while we define converting constructor between float/double.
-// - For these converting constructors, upcasting is implicit, downcasting is
-//   explicit.
-// - We also define explicit casting from std::complex/thrust::complex
-//   - Note that the conversion from thrust is not constexpr, because
-//     thrust does not define them as constexpr ????
-//
-//
-// [Operator =]
-//
-// The APIs of operator = are mostly copied from C++ standard:
-//   https://en.cppreference.com/w/cpp/numeric/complex/operator%3D
-//
-// Since C++20, all operator= are constexpr. Although we are not building with
-// C++20, we also obey this behavior.
-//
-// There are three types of assign operator:
-// - Assign a real value from the same scalar type
-//   - In std, this is templated as complex& operator=(const T& x)
-//     with specialization `complex& operator=(T x)` for float/double/long
-//     double Since we only support float and double, on will use `complex&
-//     operator=(T x)`
-// - Copy assignment operator and converting assignment operator
-//   - There is no specialization of converting assignment operators, which type
-//   is
-//     convertible is solely dependent on whether the scalar type is convertible
-//
-// In addition to the standard assignment, we also provide assignment operators
-// with std and thrust
-//
-//
-// [Casting operators]
-//
-// std::complex does not have casting operators. We define casting operators
-// casting to std::complex and thrust::complex
-//
-//
-// [Operator ""]
-//
-// std::complex has custom literals `i`, `if` and `il` defined in namespace
-// `std::literals::complex_literals`. We define our own custom literals in the
-// namespace `c10::complex_literals`. Our custom literals does not follow the
-// same behavior as in std::complex, instead, we define _if, _id to construct
-// float/double complex literals.
-//
-//
-// [real() and imag()]
-//
-// In C++20, there are two overload of these functions, one it to return the
-// real/imag, another is to set real/imag, they are both constexpr. We follow
-// this design.
-//
-//
-// [Operator +=,-=,*=,/=]
-//
-// Since C++20, these operators become constexpr. In our implementation, they
-// are also constexpr.
-//

-// [Unary operator +-]

-// Since C++20, they are constexpr. We also make them expr

+   *   - Then we multiply the single-precision result of exponent adjustment by

+   * necessary exponent adjustment by 0x70 due to difference in exponent bias.
+   *     The floating-point multiplication hardware would ensure than Inf and
+   * NaN would retain their value on at least partially IEEE754-compliant
+   * implementations.
+   *

+// to work on all devices supported by PyTorch
+//
+// Most of the APIs duplicates std::complex
+// Reference: https://en.cppreference.com/w/cpp/numeric/complex
+//
+// [NOTE: Complex Operator Unification]
+// Operators currently use a mix of std::complex, thrust::complex, and
+// c10::complex internally. The end state is that all operators will use
+// c10::complex internally.  Until then, there may be some hacks to support all
+// variants.
+//
+//
+// [Note on Constructors]
+//
+// The APIs of constructors are mostly copied from C++ standard:
+//   https://en.cppreference.com/w/cpp/numeric/complex/complex
+//
+// Since C++14, all constructors are constexpr in std::complex
+//
+// There are three types of constructors:
+// - initializing from real and imag:
+//     `constexpr complex( const T& re = T(), const T& im = T() );`
+// - implicitly-declared copy constructor
+// - converting constructors
+//
+// Converting constructors:
+// - std::complex defines converting constructor between float/double/long
+// double,
+//   while we define converting constructor between float/double.
+// - For these converting constructors, upcasting is implicit, downcasting is
+//   explicit.
+// - We also define explicit casting from std::complex/thrust::complex
+//   - Note that the conversion from thrust is not constexpr, because
+//     thrust does not define them as constexpr ????
+//
+//
+// [Operator =]
+//
+// The APIs of operator = are mostly copied from C++ standard:
+//   https://en.cppreference.com/w/cpp/numeric/complex/operator%3D
+//
+// Since C++20, all operator= are constexpr. Although we are not building with
+// C++20, we also obey this behavior.
+//
+// There are three types of assign operator:
+// - Assign a real value from the same scalar type
+//   - In std, this is templated as complex& operator=(const T& x)
+//     with specialization `complex& operator=(T x)` for float/double/long
+//     double Since we only support float and double, on will use `complex&
+//     operator=(T x)`
+// - Copy assignment operator and converting assignment operator
+//   - There is no specialization of converting assignment operators, which type
+//   is
+//     convertible is solely dependent on whether the scalar type is convertible
+//
+// In addition to the standard assignment, we also provide assignment operators
+// with std and thrust
+//
+//
+// [Casting operators]
+//
+// std::complex does not have casting operators. We define casting operators
+// casting to std::complex and thrust::complex
+//
+//
+// [Operator ""]
+//
+// std::complex has custom literals `i`, `if` and `il` defined in namespace
+// `std::literals::complex_literals`. We define our own custom literals in the
+// namespace `c10::complex_literals`. Our custom literals does not follow the
+// same behavior as in std::complex, instead, we define _if, _id to construct
+// float/double complex literals.
+//
+//
+// [real() and imag()]
+//
+// In C++20, there are two overload of these functions, one it to return the
+// real/imag, another is to set real/imag, they are both constexpr. We follow
+// this design.
+//
+//
+// [Operator +=,-=,*=,/=]
+//
+// Since C++20, these operators become constexpr. In our implementation, they
+// are also constexpr.
+//
+// There are two types of such operators: operating with a real number, or
+// operating with another complex number. For the operating with a real number,
+// the generic template form has argument type `const T &`, while the overload
+// for float/double/long double has `T`. We will follow the same type as
+// float/double/long double in std.
+//
+// [Unary operator +-]
+//
+// Since C++20, they are constexpr. We also make them expr
+//
+// [Binary operators +-*/]
+//
+// Each operator has three versions (taking + as example):
+// - complex + complex
+// - complex + real
+// - real + complex
+//
+// [Operator ==, !=]
+//
+// Each operator has three versions (taking == as example):
+// - complex == complex
+// - complex == real
+// - real == complex
+//
+// Some of them are removed on C++20, but we decide to keep them
+//
+// [Operator <<, >>]
+//
+// These are implemented by casting to std::complex
+//
+//
+//
+// TODO(@zasdfgbnm): c10::complex<c10::Half> is not currently supported,
+// because:
+//  - lots of members and functions of c10::Half are not constexpr

Subject: [PATCH 347/423] Link QNN backend to pybinding lib when built (#13467)

This change makes it possible to run QNN models with pybindings, when
enabled. It does still require the environment setup described in the
docs.

I validated this change locally by running install_executorch.sh with
CMAKE_ARGS="-DEXECUTORCH_BUILD_QNN=ON", and then lowering and running a
simple add model. The CI set up further in this stack also leverage this
feature and test it extensively.

Subject: [PATCH 349/423] Fix sigmoid operator to support boolean tensor inputs
 (#13515)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR fixes the issue where boolean tensors were rejected by the
`sigmoid` operator in ExecuTorch.
Specifically, it removes the rejection check for boolean tensors in
`op_sigmoid.cpp` and adds proper conversion logic:

* `true` → `1.0` → `sigmoid(1.0) ≈ 0.731059`
* `false` → `0.0` → `sigmoid(0.0) = 0.5`

This resolves the failure reported in **#13492**, where a boolean tensor
with shape `(4, 7, 1, 1, 7, 2)` could not be processed by
`sigmoid.default`.

### Changes

* Removed boolean rejection check in `op_sigmoid.cpp`.
* Added boolean-to-float conversion logic (`true -> 1.0`, `false ->
0.0`) before applying sigmoid.
* Added comprehensive boolean tensor tests in `op_sigmoid_test.cpp`.

### Fixes

Fixes #13492

### Test Plan

* Added new unit tests in `op_sigmoid_test.cpp` to validate behavior
with boolean tensors.
* Verified that boolean tensors now produce correct sigmoid outputs
without rejection.

Subject: [PATCH 350/423] Fix method meta error in wasm build (#13496)

### Summary
An error would occur when trying to get the metadata for a method
containing an input or output that isn't a tensor. This occurs because
there wasn't a check for the input/output tag when generating the list
of tensor metadata.

Now the list of tensor metadata will have `undefined` if the
input/output in that index is not a tensor.

### Test plan
Added unit tests to test the method metadata for a method that has ints
in its input and outputs.
Added unit test to check if getMethod works if the module has multiple
methods.

Unit tests are in the CI but can be ran with
```
bash scripts/build_wasm_tests.sh
cd cmake-out-wasm/extension/wasm/test/
npm test # after installing Jest
```

Subject: [PATCH 353/423] [Backend Tester] Add markdown summary in CI (#13535)

Add a nice markdown summary in the GitHub actions job. This will show up
when clicking on the run on a PR. It's intended to give an easy way to
see the results without needing to download the job artifact.

See https://github.com/pytorch/executorch/actions/runs/17090546309 for
example output.

Subject: [PATCH 368/423] Create stale.yml workflow to label stale PRs (#13565)

The behavior is:
- If a PR is not labeled stale, after 60 days inactivity label the PR as
stale and comment about it.
- If a PR is labeled stale, after 30 days inactivity close the PR.
- `high priority` and `no-stale` PRs are exempt.

Subject: [PATCH 376/423] [ET-VK][ez] Fix partitioner logic of finding keepdim
 arg of reduce ops (#13598)

Stack from [ghstack](https://github.com/ezyang/ghstack) (oldest at
bottom):
* #13597
* #13596
* #13595
* #13594
* #13593
* #13600
* #13599
* __->__ #13598

Title says it all. For reduce ops, their signature are not all alike so
some extra legwork needs to be done to identify specific arguments that
need to be checked.

Also included a small update to partitioner logging to improve
debuggability.

Subject: [PATCH 384/423] [Core ML] Improve asset management (#13560)

## Fix asset management issues in CoreML delegate

- Do not use the temporary directory for asset storage.
- Use the staging directory for storing temporary assets, and ensure it
is cleaned up after use.
- Perform aggressive cleanup of the temporary directory to avoid
leftovers.
- Guarantee proper cleanup of staging directories after operations to
prevent stale files.

Subject: [PATCH 387/423] NXP backend: Add support for the `aten.cat` operator.
 (#13505)

### Summary
Add delegation of `aten.cat` to Neutron, and a
`CustomDelegationOptions` class allowing delegation rules
to be overridden.

The CustomDelegationOption is introduced to allow force delegation of aten.cat operator, opportunistically, in cases when the constaint on number of channels cannot be determined automatically.

### Test plan
Unit tests provided in
`backends/nxp/tests/ir/converter/node_converter/test_cat_converter.py`.

Subject: [PATCH 389/423] Arm backend: Dont try to fuse const for TOSA ops
 (#13575)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

### Summary
The TOSA ops doesn't have any backed reference implementation, so avoid
trying to fuse constant ops and leave for the backend compiler to do the
work.

### Test plan
Tested through unit tests.

Subject: [PATCH 391/423] Cortex_m backend: Loosen edge op check. (#13550)

The pass checked that all ops were edge ops to detect if the pass was
ran before lowering to edge. However, there are cases where aten ops
survive after edge lowering, notably torch.ops.tensor_scalar. This
shouldn't crash the pass. Instead, only check that q/dq ops are edge
ops.

### Test plan
Unit tests provided.

Subject: [PATCH 393/423] Fix aten.amax lowering issue (#13381)

Summary:
There was an error when lowering amax around this line `input_tensor =
self.get_tensor(input_node, node)` and the issue is that we're trying to
permute the tensor inside node_visitors, op_node.meta[QCOM_AXIS_ORDER]
is (0, 1), however, tensor.shape is (1, 980, 49).

Rollback Plan:

Subject: [PATCH 395/423] Add check_for_installed_private_headers_in_cmake_out
 (#13485)

This adds a test that will run in CI as part of unittest jobs to make
sure that we don't install private headers.

I fixed the existing places where we were installing private headers;
reviewers, please confirm that we are OK with this technical break of
source-level backward compatibility.

Subject: [PATCH 398/423] Added JS bindings for tokenizers library (#13566)

### Summary
Added JavaScript bindings for the tokenizer library so that we can use
them to run LLMs in a web browser.

### Test plan
I will add end to end tests later.

+# Tokenizers JavaScript Bindings
+
+This directory contains the JavaScript bindings for the [LLM Tokenizers](../../llm/README.md#tokenizer) library.
+
+## Building
+
+To build Tokenizers for Wasm, make sure to use the `emcmake cmake` command and to have `EXECUTORCH_BUILD_TOKENIZERS_WASM` and `EXECUTORCH_BUILD_EXTENSION_LLM` enabled. For example:
+
+```bash
+# Configure the build with the Emscripten environment variables
+emcmake cmake . -DEXECUTORCH_BUILD_TOKENIZERS_WASM=ON \
+    -DEXECUTORCH_BUILD_EXTENSION_LLM=ON \
+    -DCMAKE_BUILD_TYPE=Release \
+    -Bcmake-out-wasm
+
+# Build the Wasm extension
+cmake --build cmake-out-wasm --target tokenizers_wasm -j32
+```
+
+Emscripten modules are loaded into the global `Module` object by default. This means you cannot have multiple modules in the same page. If you are also using the ExecuTorch Wasm bindings, it is recommended to use the `MODULARIZE` option to avoid conflicts.
+
+In your CMakeLists.txt, add the following lines:
+
+```cmake
+add_executable(tokenizers_wasm_lib) # Emscripten outputs this as a JS and Wasm file
+target_link_libraries(tokenizers_wasm_lib PRIVATE tokenizers_wasm)
+target_link_options(tokenizers_wasm_lib PRIVATE -sMODULARIZE=1 -sEXPORT_NAME=loadTokenizers) # If EXPORT_NAME is not set, the default is Module, which will conflict with ExecuTorch
+```
+
+You can then access the module with `mod = await loadTokenizers();` or `loadTokenizers().then(mod => { /* ... */ });`.
+
+For example, to load the module in a HTML file, you can use the following:
+
+```html
+<script src="tokenizers_wasm_lib.js"></script>
+<script>
+  var Module = {
+    onRuntimeInitialized: async function() {
+      // Load Tokenizers Module after ExecuTorch Module is initialized
+      const tokenizersModule = await loadTokenizers();
+      const sp = new tokenizersModule.SpTokenizer();
+      // ...
+    }
+  }
+</script>
+<script src="executorch_wasm_lib.js"></script>
+```
+
+You can read more about Modularized Output in the [Emscripten docs](https://emscripten.org/docs/compiling/Modularized-Output.html).
+
+## JavaScript API
+
+### Supported Tokenizers
+- `HFTokenizer`
+- `SpTokenizer`
+- `Tiktoken`
+- `Llama2cTokenizer`
+
+### Tokenizer API
+- `load(data)`: Load tokenizer data from a file or a buffer.
+- `encode(text, bos=0, eos=0)`: Encode a string into a list of tokens with the number of bos tokens to prepend and eos tokens to append to the result.
+- `decode(tokens)`: Decode a list of tokens into a string.
+- `vocabSize`: The number of tokens in the vocabulary.
+- `eosTok`: The end-of-sequence token.
+- `bosTok`: The begining-of-sequence token.
+- `isLoaded`: Whether the tokenizer is loaded.

-In the [Running an ExecuTorch Model in C++ Tutorial](running-a-model-cpp-tutorial.md), we explored the lower-level ExecuTorch APIs for running an exported model. While these APIs offer zero overhead, great flexibility, and control, they can be verbose and complex for regular use. To simplify this and resemble PyTorch's eager mode in Python, we introduce the `Module` facade APIs over the regular ExecuTorch runtime APIs. The `Module` APIs provide the same flexibility but default to commonly used components like `DataLoader` and `MemoryAllocator`, hiding most intricate details.

 ```bash
-python examples/qualcomm/oss_scripts/llama/llama.py -b build-android -s ${SERIAL_NUM} -m ${SOC_MODEL} --prompt "What is 1+1?" --temperature 0 --model_mode kv --max_seq_len 1024 --ptq 16a8w --decoder_model qwen2_5 --eval_perplexity --tasks wikitext --limit 1

 ```
 
 For the example 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.
 Example:
 ```bash
 # 1st run to compile with --limit 1

Subject: [PATCH 406/423] Qualcomm AI Engine Direct - Improve GA Static
 Phi-4-mini accuracy (#13573)

Summary:

- Refactor custom annotation for R3
- Fix warning message in quantization
- Add phi-4-mini setting into README
- Fixed segmemtation fault when run the model with sharding
- Add a test case for phi-4 in test_qnn_delegate.py
- Add new parameter "group_size" in llama.py to set block size in block
quantization

## Sample Script
```
python examples/qualcomm/oss_scripts/llama/llama.py -b build-android -s ${SERIAL_NUM} -m ${SOC_MODEL} \
--ptq 16a4w_block --group_size 16 --checkpoint consolidated.00.pth --params params.json --num_sharding 4 \
--tokenizer_model tokenizer.model --decoder_model phi_4_mini --model_mode hybrid --prefill_ar_len 128 \
--max_seq_len 1024 --prompt "I would like to learn python, could you teach me with a simple example?"
```

## Result
Stats with QNN2.37.0 on SM8750
Accuracy: 10.82
Token Rate: 22.727273
Results:
--prompt "I would like to learn python, could you teach me with a simple
example?"
```
<|user|>I would like to learn python, could you teach me with one simple program?<|end|><|assistant|>Of course! Let's get started with a simple Python program. We'll create a simple program that asks for your name and then greets you.

```python
# Ask for the user's name
name = input("Please enter your name: ")

# Greet the user
print(f"Hello, {name}! Welcome to the world of Python.")
```

To run this program, you would need to copy the code into a Python environment (like an IDE or a Python interpreter). When you run the program, it will prompt you to enter your name, and then it will greet you by name. Enjoy learning Python!<|end|>
```

## Test plan
Added E2E test to test_qnn_delegate.py

Subject: [PATCH 408/423] Fix error reporting in Windows preset build job
 (#13247)

Update the Windows preset build job to accurately report failure.
Previously, it was silently failing.

I've updated the script to explicitly check the last exit code. I'm not
entirely sure why ErrorActionPreference=Stop isn't doing this. I played
around with the escaping a bit and also added
PSNativeCommandUseErrorActionPreference = True, but haven't gotten it to
fail on exit code. It might be possible to make this work, but I'm just
adding an explicit check for now.

Subject: [PATCH 409/423] Fix devtools CMake build failure on Windows (#13251)

Update the devtools bundled program build to work on Windows by using
the non build interface string to create the directory. I'm not entirely
sure why this was working on Mac/Linux, but looking at the other
devtools cases where a directory was created at configuration time(?),
it was using the non build interface path variable
(DEVTOOLS_INCLUDE_DIR_NO_BUILD_INTERFACE), so this would appear to be
the correct behavior.

Note that the Windows pybind job is still failing on this PR, but is
failing later. Without this change, the CMake configuration step fails.
Now, it fails in the actual build - one step closer.

Subject: [PATCH 410/423] Create Windows CMake preset (#13257)

Create a CMake preset for Windows, based on what is currently buildable.
Add to CI. A lot of things are currently broken, including portable
kernels and XNNPACK. I've disabled these (and more) to allow setting up
the initial preset and CI. These build issues will be resolved further
in this stack.

I've also disabled the pybind preset on Windows for now, as it does not
build yet.

Subject: [PATCH 420/423] Arm backend: Use cmake for building in Ethos-U
 jupyter example (#13630)

Building the example application using cmake is now straight forward
enough to not need any helper scripts.

Additionally simplify the the example + path setup in the executor
runner cmake script and make the default path match the example.
