From 154b84f0a54356971ccc29f010e691c36b93f6bf Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 30 Sep 2026 19:54:11 +0100 Subject: [PATCH 01/34] cmake: microwakeword: dynamic toolchain, libc shim, and compiler discovery Support building microWakeWord with external or dynamic toolchain configurations where libc.a / libm.a archive layouts differ between Xtensa toolchain versions. Specifically: - Check for XTENSA_SYSTEM libc archive path when not found in standard Zephyr paths. - Check libc archive member names to extract either Newlib (lib_a-*.o) or standard libc/libm members into the shim archive. - Run mww_shim_flatten.py to flatten .text.* and .literal.* sections into .text and .literal to prevent CALL8 out-of-range relocation overflows. - Enable -mlongcalls and -mtext-section-literals on Xtensa architecture builds. - Conditionally include ibuffer_allocator.cc when present in the TFLM tree.

Also emit WOV_ARB_CMD_RESUME to unpause detectors. - Drain Streaming: ensure the arbiter only produces data when an active slot is triggered, leaving the host PCM idle/blocked during low-power listening so the platform can enter D0i3. - Update wov_arbiter README documentation.

From 094710e6bbea1919fb7bf0b855c9621e47e6e836 Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 30 Sep 2026 19:55:25 +0100 Subject: [PATCH 09/34] audio: microwakeword: use static storage for op resolver and interpreter to fix heap leak TFLite Micro defines TF_LITE_REMOVE_VIRTUAL_DELETE on MicroMutableOpResolver, which expands to a no-op 'void operator delete(void* p) {}'. Consequently, calling 'delete inst->op_resolver' in MWW_Free() never returned the memory to the heap, leaking ~600 bytes per slot on every stream open/close cycle. Across multi-slot configurations (3 detector slots), repeated stream cycles exhausted the DSP system heap, failing on run 10 with -ENOMEM in MWW_InitOps() and returning -22 (IPC4_INVALID_REQUEST) to snd_pcm_start(). Eliminate heap allocations from MWW model initialization by allocating both MwwOpResolver and MicroInterpreter in aligned static storage using placement new and explicit destructor invocation. Verified with 10 consecutive D0i3 sleep-and-wake test cycles on Panther Lake hardware (Aphid), achieving 10/10 passes with zero errors.

HcmV?d00001 From cec57e87baea2572d5f95f1d1eedbf1654fb9266 Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 30 Sep 2026 19:57:16 +0100 Subject: [PATCH 16/34] tools: wov_capture: add blocking read utilities and S0/D0i3 test runner Add test utilities for verifying Wake-on-Voice capture pipelines: - wov_blocking_read.c: alsa-lib utility that opens the WoV capture PCM in blocking read mode with SND_PCM_NO_IRQ_WAITEVENT or mmap to ensure the driver does not generate periodic IRQs during listening. - wov_blocking_read_tinyalsa.c: TinyALSA version of the blocking reader. -

System Dependencies & Prerequisites + +To reproduce this test case, both the host Linux kernel and the SOF DSP firmware must include the required IPC4 and PCM wakeup enhancements: + +#### A. Linux Kernel Subsystem (`sound/soc/sof`) +* **Repository**: `git@github.com:lgirdwood/linux.git` +* **Branch**: `wov-ipc4-d0i3` +* **Required Kernel Patches**: + 1. `ASoC: SOF: Intel: hda-pcm: support NO_PERIOD_WAKEUP and ignore suspend for WoV capture` ([`hda-pcm.c`](file:///home/lrg/work/linux-ptl/sound/soc/sof/intel/hda-pcm.c)): + - Advertises `SNDRV_PCM_INFO_NO_PERIOD_WAKEUP` on `d0i3_compatible` capture streams. This permits user space to disable ALSA's internal period wakeup timer, allowing `snd_pcm_readi()` to block indefinitely waiting for a wake phrase rather than timing out with `-EIO` after \(\sim 1.1 \times \text{buffer\_duration}\) seconds of silence. + - Sets `rtd->dai_link->ignore_suspend = 1` while the WOV capture stream is open, preventing generic ASoC DAPM from destroying active DSP pipeline widgets during system suspend. + 2. `ASoC: SOF: ipc4: handle phrase detected notification to wake WoV capture stream` ([`ipc4.c`](file:///home/lrg/work/linux-ptl/sound/soc/sof/ipc4.c)): + - Catches `SOF_IPC4_NOTIFY_PHRASE_DETECTED` notifications dispatched by the DSP and calls `snd_sof_pcm_period_elapsed()` on the capture substream, unblocking the waiting userspace `read()` thread. + +#### B. SOF DSP Firmware (`sof`) +* **Repository**: `git@github.com:lgirdwood/sof.git` +* **Branch**: `wcl-uaol-wov-002` +* **Required Firmware Patches**: + 1. `audio: kpb: support multi-sink topology binding and synchronous reset on IPC4` ([`kpb.toml`](file:///home/lrg/work/work-extra/sof-wcl/sof/src/audio/kpb.toml), [`kpb.c`](file:///home/lrg/work/work-extra/sof-wcl/sof/src/audio/kpb.c)): + - Declares 2 sink pins (Pin 0 = `sel_sink` real-time detector feed, Pin 1 = `host_sink` drain) so the drain path can be bound from topology. + - Guards asynchronous `-EBUSY` resets with `#if !CONFIG_IPC_MAJOR_4` so IPC4 pipeline resets execute synchronously. + 2. `ipc4: handler: add D0ix state notifier and handle COMP_STATE_PREPARE in pipeline ops` ([`handler-user.c`](file:///home/lrg/work/work-extra/sof-wcl/sof/src/ipc/ipc4/handler-user.c)): + - Handles `COMP_STATE_PREPARE` as a valid no-op state for `RUNNING` and `RESET` pipeline transitions, preventing spurious error 7 (`IPC4_INVALID_REQUEST`) during back-to-back stream restart. + 3. `audio: wov_arbiter: notify host on detection and handle KPB drain streaming` ([`wov_arbiter.c`](file:///home/lrg/work/work-extra/sof-wcl/sof/src/audio/wov_arbiter/wov_arbiter.c)): + - Dispatches `SOF_IPC4_NOTIFY_PHRASE_DETECTED` to the host upon detection and periodically every 320 frames during audio drain. + - Keeps sink silent during listening (`WOV_ARB_NO_ACTIVE`) so the host PCM stays blocked in `read()` and allows platform D0i3 entry. + 4. `audio: microwakeword: add fake wake test aid and improve stream lifecycle` ([`mww.c`](file:///home/lrg/work/work-extra/sof-wcl/sof/src/audio/microwakeword/mww.c), [`Kconfig`](file:///home/lrg/work/work-extra/sof-wcl/sof/src/audio/microwakeword/Kconfig)): + - Adds `CONFIG_COMP_MWW_FAKE_WAKE_MS` to synthesize keyword detections after a configured delay for test automation. + - Arms fake-wake deadlines on `mww_prepare()` so S0-only tests fire reliably, and separates one-time model initialization from stream state. + +#### C.

[PATCH 21/34] mww: align IPC4 microWakeWord slot ID with reverse DAPM instance allocation In IPC4, the Linux kernel assigns module instance IDs sequentially as it traverses DAPM widgets. Because widgets are stored in a LIFO linked list (list_add), the widgets in pipelines 101, 102, 103 are instantiated in reverse order: - mww.103.1 -> instance 0 - mww.102.1 -> instance 1 - mww.101.1 -> instance 2 Previously, mww.c derived slot_id as (IPC4_INST_ID(dev->ipc_config.id) % 3), which assigned slot 0 to mww.103.1 and slot 2 to mww.101.1. When the host triggered wovdebug_101, the arbiter received slot 2 and set wov_active_slot to 3 ('Slot 3'), inverting slots 1 and 3. Align with detect_test.c by computing: cd->wov_slot_id = (uint8_t)(2 - (IPC4_INST_ID(dev->ipc_config.id) % 3)); This ensures: - wovdebug_101 (Pipeline 101) -> slot 0 -> wov_active_slot = 1 ('Slot 1') - wovdebug_102 (Pipeline 102) -> slot 1 -> wov_active_slot = 2 ('Slot 2') - wovdebug_103 (Pipeline 103) -> slot 2 -> wov_active_slot = 3 ('Slot 3') Also update wov_blocking_read.c and run_wov_10x.py: - wov_blocking_read queries wov_active_slot upon receiving audio frames and asserts that triggered active_slot matches the expected slot. - run_wov_10x.py logs and validates trig_slot == slot for each iteration. - Validated on Aphid hardware across 10x S0 and 10x D0i3 runs (20/20 PASS).

On 4-mic platforms (e.g. sof-adl-max98357a-rt5682-wov-multi) the NHLT only carries 4ch DMIC blobs, so the kernel fails to start the ECNS capture with: no matching blob for sample rate: 16000 sample width: 16 channels: 2 Add DMIC_WOV_DAI_CHANNELS (default 2) and set it to 4 in dmic-generic when NUM_DMICS is 4.

The LL copy of a pipeline starts from a single source component (ipc_get_ppl_comp() -> pipeline_copy()) and walks downstream, so only mixout.115.1 was ever copied. mixout.115.2 never moved data, ECNS pin 0 stayed empty and nothing reached the KPB or the detectors, while the dmic16k DMA overran. Drop both mixin/mixout pairs (mixin.119.1/mixout.115.2 and mixin.110.1/mixout.115.1) and bind the dmic16k and dmic01 DAI copiers in pipelines 119 and 110 straight to ECNS input pins 0 and 1.

In wov_arb_copy(), simplify active source buffer discovery, compute copy frames using MIN(src_frames, dst_frames) with exact audio_stream_frame_bytes(), and add buffer_stream_invalidate() / buffer_stream_writeback() for cache coherency. Remove synthetic silence insertion (fill_bytes), which injected zero frames when the source momentarily had fewer frames than the sink had free space, corrupting continuous audio data streams.
