This repo run ops on Apple ANE in NPU register with pure python and numpy on M1 Asahi Linux. No Espresso, No CoreML, no metal, no .mlmodels file, no .hwx file, no ANEcompiler, no private Apple API, no anecc, nothing. Even numpy is optional.
The Orion GPT-2 text-generation port reads cached Hugging Face
weights, regenerates ANE tile-packed coefficients into the external cache,
and includes tokenization, KV caching, a CPU backend, and an M1 ANE replay backend with
first-run numerical checks. Start with gpt2/first-run.sh. On base M1 Asahi,
all 24 decode kernels and full generation parity passed. After reducing output
copies and defaulting OpenBLAS to one thread, four 32-token runs measured
58.18 generated tokens/s combined; warmed decode measured 70.18 steps/s
for the two-token prompt. See the
Asahi measurements for timing scope.
Mirai Qwen3.5-0.8B-M now has a packed W4 CPU runtime,
an independent Uzu BF16 reference check, and experimental Linux M1 ANE
projections. Start with qwen35/first-run.sh setup, then verify or
generate. Separate prefill and decode measurements
now cover short, 128-token and 512-token prompts on CPU and ANE. CPU SDOT
matched every saved token choice. The corrected ANE policy scales and
compensates FP16 projections using spare batch rows, with one hardware
submission per projection. Three matched runs now passed all 576 decode
choices with maximum full-logit NRMSE 0.381%, down from 17.30%. Paired
ANE decode fell from 17.38 to 11.57 tok/s. The CPU path is the default.
Active desktop load and paging limit speed comparisons. No new macOS dump was used.
For a separate macOS Core ML comparison, see the Core ML Qwen3.5 notes. They record graph-lowering and placement lessons from an upstream ANEMLL port; this repository's runtime remains the direct-register Asahi implementation described here.
Whisper now runs trained tiny.en on this Asahi M1 using
the existing matrix stream for 24 encoder projections, with other operations
and decoding on CPU. No new macOS dump was used. All 80 captured raw logit
argmaxes match CPU and the independent HF model across three clips, with
maximum full-logit NRMSE 0.333% versus HF. Host and CPU kernel optimizations
reduced ANE encode time from 721.41 to 345.80 ms.
The Asahi warm table measures 468.18 ms
to transcribe the 11-second JFK clip using ANE projections, versus 417.49 ms
on CPU. The macOS table measures five routes;
its full-encoder ANE + CPU decoder took 68.37 ms. The graph and CPU backends
differ, and the Linux hybrid is currently slower.
PR ANEForge fast encoder speed reference on M1 (2026-10-08). These runs use multilingual tiny/base/small, the full 1,500-position audio context and four threads. Encoder time includes input staging, the full ANE encoder and CPU cross-attention K/V; compilation and decoding are excluded.
| Model | macOS: ANE + Accelerate BLAS measured | macOS: ANE + OpenBLAS NEON measured | Asahi: ANE + OpenBLAS measured |
|---|---|---|---|
| tiny | 17.17 ms | 28.65 ms | 32.13 ms |
| base | 36.69 ms | 63.30 ms | 72.70 ms |
| small | 142.51 ms | 334.71 ms | 282.32 ms |
All three ran on Asahi with the unchanged Mac timing harness: two persistent contexts, two excluded warmups and five measurements each. The ten measured calls ranged 31.98–32.48 / 72.35–75.57 / 281.02–288.75 ms for tiny/base/small. Native blocking ANE dispatch medians were 14.24 / 30.22 / 106.86 ms, and readback medians were 1.33 / 1.81 / 2.71 ms. Each model's zero-mel encoder output matched its Mac hash byte for byte on all 23 calls of a separate three-warmup/twenty-measurement replay, including small's two coefficient banks. Compared with saved Mac OpenBLAS medians, tiny/base took 12.1% / 14.8% longer and small took 15.7% less time. The libraries differ (Fedora OpenBLAS 0.3.29 versus Mac 0.3.34), clocks were not controlled, and small's Mac samples ranged 297–406 ms; these results do not isolate the source of the difference. These are encoder timing comparisons with exact Mac zero-input output agreement. Separate local speech checks now measure maximum encoder relative L2 error against an independent FP32 reference of 3.63% / 1.87% / 2.66% for tiny/base/small. The corresponding strict numerical checks fail, while all 81/84/90 raw token argmaxes match. These are local numerical results, separate from the exact Mac zero-mel replay comparison and the encoder timing boundary. See the tiny, base and small accuracy receipts. The latest tiny run also profiles the loaded driver at its original 1-us poll setting: the last native call in each context spent about 14.21 ms waiting for completion and 0.009 ms draining IRQ events. These are driver wall times, with no ANE clock or hardware-duration counter available. See Asahi receipts for tiny profiled rerun, base and small, Mac measured runs, benchmark details and checkpoint repacking/native replay. Large weights and HWX dumps remain ignored; Asahi rebuilds them from external safetensors or lossless F16/F32 GGUF using the compact packing recipes.
Accuracy-qualified tiny.en paired control. Native Asahi whisper.cpp now reuses the macOS C++ packing and FP32 combination arithmetic with a Linux DRM transport. All 80 full-vocabulary decoder vectors pass NRMSE < 0.005 versus CPU and independent HF, with matching histories/raw argmaxes. Worst paired/HF NRMSE is 0.408%; repeated mel, encoder outputs and complete decoder traces are byte identical on all three clips. Each encode uses 24 submissions / 32 hardware tasks and four existing graph workers.
| Tiny.en, 11-second JFK clip | Encoder + cross-K/V | Decoder total | Whole transcription |
|---|---|---|---|
| macOS FP32 CPU + Apple BLAS — saved | 252.24 ms | 85.94 ms | 369.01 ms |
| macOS paired ANE + Apple BLAS — saved | 366.88 ms | 87.14 ms | 483.76 ms |
| Asahi FP32 CPU + OpenBLAS — measured | 216.57 ms | 72.95 ms | 307.35 ms |
| Asahi paired ANE + OpenBLAS — measured | 624.32 ms | 78.79 ms | 723.42 ms |
Each backend has two persistent contexts, two excluded warmups and ten measurements per clip per context, four workers and a full 30-second encoder context. The paired path remains slower than CPU and macOS. Linux readback takes 379.37 ms for 332.66 MB of padded FP16 products, versus 13.34 ms in blocking ioctl. The buffers use the driver's write-combined mapping; packing and combining take 10.43 / 12.50 ms. CPU BLAS libraries and frontends differ across hosts, and clocks were not fixed. This validates native accuracy on local matching inputs; exact Mac speech arrays and E5RT executable identity remain unverified. The original fused fast graph still fails its separate strict accuracy gate. Native Asahi receipt, saved Mac receipt and shared preparation/run commands.
GPT-2 training on Asahi replays the captured forward and backward kernels through the same driver. A full 124M parameter run completed ten Adam updates on this machine; its fixed-batch loss fell from 4.42788 to 0.000207. The transformer runs on ANE, with the vocabulary head, loss and optimizer on CPU.
The unrestricted rerun receipt records the latest hardware results after the execution sandbox was removed. The initial follow-up receipt retains the earlier restricted attempts. Capture and replay commands retain the measurement boundaries and remaining native Asahi checks.
The subsequent review verified macOS MUL execution through private MIL compilation: both 64-value cases pass exactly. ANEForge's private E5RT path also works. Our custom HWX dumps are assigned to guarded Asahi replay; standalone macOS loading is a retained historical rejection control. The runtime scope records that boundary. Replay validation now rejects empty fixtures and changed gates before device access; benchmark observations bracket process start and exit. Earlier timing classifications retain their sampled scope.
The macOS CPU results cover 18 Qwen3.5 runs and the GPT-2 package, CPU parity and warmed decode checks. All 97 retained artifact hashes and the evidence archive hash were rechecked. The current GPT-2 inference/training and Qwen projection shapes already have validated templates; their existing replay paths do not need fresh HWX dumps.
| Follow-up | Result | Remaining work |
|---|---|---|
| Qwen BF16 Uzu layer captures for arithmetic prefixes 3–23 | Completed on macOS: native BF16 matches independent Uzu at all 23 tokens, 552 layer vectors and 5,711,360 logits. Both Mac implementations differ from the retained Asahi arithmetic logits. | Compare independent all-token captures on Asahi using the retained Cargo lock; keep the original exact fixtures. |
| Quiet, repeated CPU measurements | Three phases completed: 54/54 numerical runs passed. Thirteen passed the sampled host-activity gates; 41 timings were affected. The unrestricted phase passed 18/18 with complete host queries, including five timings passing the sampled gates. | All attempts are retained; these same-boot phases do not establish an isolated OS comparison. |
| Longer-context and free-generation numerical checks | Completed CPU checks: 1K/2K contexts and four shorter prompts, 384/384 decode choices; four independent greedy streams, 256/256 choices. All full-logit errors passed the unchanged 0.5% gate. | Floating traces and an accurate-ANE invocation are retained for native Asahi replay. |
| Static HWX compile-options investigation | Seven variants exported identical one-task MUL structures. Historical custom-HWX macOS loading controls failed; the MUL computes exactly through private E5RT and daemon-compiled MIL. | Custom exported HWX execution belongs on Asahi. Standalone macOS loading is removed from pending work; option recognition and native Asahi replay remain separate questions. |
| Whisper trained encoder and more audio | The original fast 1,779-task graph is freshly recaptured as a 149 KiB package, with native input strides and byte-exact external-weight repacking. Warm 11-second transcription takes 15.83 ms encode / 66.81 ms whole. All three encoder outputs and 80 raw token choices match; the 1,783-task wrapper remains a slower baseline. | The original fast graph also fails the strict full-logit gate on Mac. New original-package Linux replay and matching stage profiles remain pending; see the review. Constructed clips do not establish diverse-corpus accuracy or WER. |
| 64-token training | All 27 templates exported with actual ANE output fixtures. Independent loss/gradient gates and three updates passed, with 580 actual ANE dispatches per update; loss fell from 3.271003 to 0.428595. Replay guards pass. | Native Asahi fixture replay and model-level training validation. |
| Fused Qwen recurrence | All 16 real-input cases pass on ANE after compensated scaling and explicit exponential SiLU. Maximum state/output NRMSE is 0.294%/0.317%, below the unchanged 0.5% gate. Four programs export with actual ANE fixtures and pass replay guards. | Native Asahi replay remains pending; this layer-0 probe does not enable a fused full-model decoder. |
The Qwen follow-up details describe
the numerical gates and required reference captures. The separate
mlx-ane-sd/task.md capture remains assigned to the other session and is
excluded from this review. GPT-2 CoreML/Orion/MLX comparisons already have
retained macOS reports; repeating them adds value when testing a changed
implementation or making a more controlled performance comparison.
The newly added Whisper measurements
already cover five macOS routes on one short clip. The new follow-up adds
Core ML inference and three constructed durations. Its unrestricted ANE,
Metal and Core ML results are recorded separately from the historical
restricted attempts and the earlier warm-context measurements.

TODO
- mac12 run hwx
- Convert whisper on MacOS v12
- Intergrate ANE to tinygrad like my fork on RK3588 NPU
- Continue eiln effort to merge ANE kmd to mainline
- Add ANE support to mesa, which NPU baseline work has been merged by Tomeu Vizoso
- Add MacOS 13+ support to anecc, I have reversed the firmware with GhidraMCP. One extracted parseTD function at parseTD.cpp
- Complet the Register Programming Guide
- borrow maderix/ANE ideas to train LLM in ANE but with pure register programing
For base M1 (T8103), the runtime overlay and loadable KMD
can supply the missing ANE device tree nodes without rebuilding the kernel or
changing boot files. Build with make -C kmod, install with
sudo make -C kmod install, then load with sudo modprobe ane.
Revalidated on a base M1 MacBook Air after upgrading to Fedora Asahi Remix 44
and booting 7.1.13+: all ten operation checks, runtime autosuspend, driver
unload/reload, and kernel fault checks passed with the runtime overlay. GPT-2
ANE inference also passed all 49 reference kernels and a fresh 32-token
generation; see the inference results. See the linked
instructions for kernel requirements, permissions and hardware validation.
This replaces the incomplete old libane/ane-overlay.dts recipe; do not apply
that old overlay to the boot device tree.
The earlier Asahi Linux Fedora 6.14.8 overlay setup worked once, but its boot installation steps were not reproducible. Use the documented runtime path above for the new overlay work.
✅ Tested on Asahi Linux fedora 6.19.11+ built from my fork of fairy-dust branch of asahi linux
The kernel build below describes the earlier setup and the optional Type-C display work. Base M1 users can use kmod for ANE without this kernel rebuild.

# Note monitor suport only on one blessed typec port on M1An existing ~/linux build can reuse its object files only when the source,
compiler, linker, flags and relevant configuration remain unchanged. The
current 7.1.13+ tree recorded GCC 15.2.1 and GNU binutils in its build
configuration. Set the paths below to that exact compiler and linker. Kbuild
rebuilds all C objects when the compiler version differs, so do not use generic
gcc or ld after a Fedora upgrade without checking them. If the matching
toolchain is unavailable, use the fresh LLVM build above. Keep the existing
.config, .o and .cmd files for this incremental path.
Rust support can work with GCC for compatible configurations. The current ARM64 configuration has no LTO, KASAN or randstruct enabled and has the BTF language-exclusion support required by Rust. Check toolchain availability and the resolved configuration before building:

generate the initramfs and register the boot entry. Check that installation
finishes successfully before rebooting. This build retains release 7.1.13+,
so installation replaces the existing entry for that release.
Reboot into the updated kernel, then run sudo modprobe asahi and check
ls -l /dev/dri/renderD*. The running Rust-disabled kernel cannot load the
new Rust driver by itself. Rebuild and reinstall the ANE runtime overlay
and KMD against the updated kernel before loading ANE.
Do not run make clean or make mrproper for this incremental path.
Kernel Rust toolchain requirements describe GCC configuration limits; a complete LLVM build remains the best supported alternative if the GCC build encounters a toolchain limitation.

- Kernel: 1×1 pointwise (ConvCfg kw=1, kh=1), all 9 weights = 2.0
- Output: each channel = 1×2 + 2×2 + 3×2 = 12 ✓
Bug fix: The original kernel_hex had 12 extra leading zero bytes, shifting all 9 weight positions by 6 fp16. This caused the KDMA to read zeros instead of the actual 2.0 weights. The fix uses the compiled .ane file which has the kernel data in the proper format.
Which one is the reference? conv_from_hwx.py is the original HWX-parsed version (loads firmware from hwx/tinygrad/conv.hwx). conv_from_relu.py was derived by adapting the relu structure with conv register values. Both use the same firmware + kernel data and produce identical results.
Common pitfalls:
- The kernel hex must be byte-exact to the reference (wrong kernel weight positions caused channels 1 and 2 to show ~0 instead of 6.0 and 12.0)
- Both files require the conv.hwx firmware file at
hwx/tinygrad/conv.hwx - The input data layout uses STRIDE=32 between channels, matching the firmware's expected layout

Relu uses TileDMA source + conv pipeline (Family 2). Three examples demonstrate different approaches:
1. Raw firmware (examples/relu.py): Uses the relu.hwx firmware as-is with TileDMA source registers. Works standalone with no L2 priming.

2. From add (experimental/relu_from_add.py): Derived from the add.py firmware structure, uses an alternative L2-style register layout where L2Cfg=0x6c013800 acts as a stream header redirecting to TileDMA Src bank. Works standalone.

3. L2-source standalone (examples/relu_l2.py): Uses L2 cache controller for input data sourcing instead of TileDMA. The SrcStream header at host 0x168 is re-routed from ANE 0x13800 (TileDMA Src) to ANE 0x04800 (L2). No firmware modules loaded. PE/NE disabled — the conv pipeline naturally clamps negative inputs to zero (ReLU behavior is in hardware, not software). The np.maximum in the Python script only computes the expected output for comparison.

The L2's SourceCfg/SourceBase/SourceRowStride registers (placed at the re-routed TileDMA Src region 0x16C-0x1AC) handle input data sourcing. No firmware modules are loaded (all-zero FW DMA context at 0x2C). PE and NE are fully disabled — the conv pipeline naturally clamps negative inputs to zero without NE activation.
| Aspect | TileDMA (relu.py) |
L2 (relu_l2.py) |
|---|---|---|
| Firmware loaded | Yes (DMA_ACTIVE entries) | None (all-zero KDMA) |
| Pipeline stages | TileDMA→Conv→PE→NE→L2→Dst | L2→Conv→Dst |
| Startup time | Longer (firmware init) | Instant |
| NE ReLU | Hardware via MACCfg bit 16 | Conv pipeline clamps negatives |
| Code complexity | 320 lines, structured registers | 113 lines, hex blob |
| Flexibility | Multi-input, advanced strides | Single sequential source |
L2 is better for simple pass-through ops (relu, identity) — no firmware loading, shorter pipeline, fewer registers. The conv pipeline naturally clamps negatives to zero without NE.
TileDMA is better for complex ops (conv, gemm, concat) needing multi-input, kernel weights, or advanced addressing patterns.
There is no elementwise_l2.py — elementwise add needs PE/NE active for actual computation (summing two inputs), which defeats the purpose of the L2 approach. The L2 vs TileDMA comparison is fully demonstrated by relu.py vs relu_l2.py.
Cin=512, Cout=512, uses TileDMA source + KDMA kernel weights. The __TEXT.__const section in the original .hwx has all-zero weights (generated with np.zeros for pipeline testing). With injected non-zero weights, GEMM produces correct output:

The zero-weight bug: The original gemm.hwx from tinygrad has __TEXT.__const full of zeros (524288 bytes, 0 non-zero fp16 out of 262144). Generate a new one on macOS with real weights:
# In gen_mlmodel.py:
K = 512
weights = np.random.randn(K, K).astype(np.float32) # non-zero!
builder.add_inner_product(name='ip_layer', W=weights, ...)Or inject weights directly (as gemm.py does) — no macOS needed for this approach.

NOTE: GEMM kernel weights are all zero in tinygrad modelInput: 512 elements at STRIDE=32 (SrcRowStride=0x40=64 bytes). Without real weights, any input gives 0.
Root cause: The gemm.hwx Mach-O __TEXT.__const section (524288 bytes = 512×512 weight matrix) is all zeros. The tinygrad model file was generated for ANE pipeline testing without actual trained weights.
Follow the same process as Section 1 "Generate hwx", but modify gen_mlmodel.py:
For GEMM (inner_product):
# In gen_mlmodel.py, uncomment the inner_product line:
K = 512
weights = np.zeros((K, K)) + 3.0 # non-zero weights!
# or: weights = np.random.randn(K, K).astype(np.float32)
bias = np.ones(K)
builder.add_inner_product(name='ip_layer', W=weights, b=bias,
input_channels=K, output_channels=K, has_bias=True,
input_name='image', output_name='probs')For CONCAT:
input_features = [('image', datatypes.Array(16)), ('image2', datatypes.Array(16))]
output_features = [('probs', datatypes.Array(32))]
builder = NeuralNetworkBuilder(input_features+input_features2, output_features)
builder.add_elementwise(name='concat', input_names=['image', 'image2'],
output_name='probs', mode='CONCAT')Then on macOS:
python gen_mlmodel.py # generates test.mlmodel
./coreml2hwx ./test.mlmodel # ANE compiles and dumps .hwx
cp /tmp/hwx_output/test/model.hwx ./gemm.hwx # or concat.hwxCan GitHub Actions work? Yes, for weighted ops. GH Actions only has macOS 14 runners, but:
- Weighted ops (GEMM, Conv, Sigmoid):
CoeffDMAConfig=0x81in our gemm.hwx proves macOS 14 correctly generates real KDMA. The existing zero weights come fromnp.zerosingen_mlmodel.py, not from macOS version. Changing to non-zero weights on GH Actions will produce correct.hwxfiles. - Elementwise ops (Add, Mul, Relu): macOS 14 adds spurious
CoeffDMAConfig=0x80entries (all 16 channels) that macOS 12 doesn't. Thehwx2py --no-cleanflag preserves them, or use--use-aneccwhich strips them automatically. The KDMA data in__TEXT.__constis zero anyway for elementwise ops (no weights needed), so the spurious entries don't affect correctness — they just add noise.
macOS 12 Monterey (real machine or VM) is only strictly needed for clean elementwise hwx files without any spurious KDMA entries.
Cin=16, Cout=16, TileDMA source, 2 inputs (16 + 16384 → 16400 output). Loads kernel data from compiled .ane file — anecc handles the KDMA kernel region setup properly.
Concat is the only multi-tile example — all others (add, relu, conv, gemm, sigmoid) use td_count=1. Concat chains 2 task descriptors via W7=0x300 (next_ptr) and requires td_count=2 with tsk_size=0x574 (total size of both tiles) in the submit call. Using td_count=1 causes tile 2 to be silently skipped.

[[5.]]]] -
Add PASS/FAIL validation with tolerance instead of just printing: match = np.allclose(output, expected, atol=0.1) print(f"{'PASS' if match else 'FAIL'}")
-
Add a batch test mode (--all flag or mode="all") that runs all ops and reports results, like the RKNPU version's loop.
-
Add SUB support — the ANE PE can do a - b = a + (-b), achievable by negating the L2 source for the second operand.
-
Use np.allclose for comparison instead of printing arrays side-by-side — makes pass/fail obvious at a glance.
