From 154b84f0a54356971ccc29f010e691c36b93f6bf Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 30 Sep 2026 19:54:11 +0100 Subject: [PATCH 01/17] 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 09/17] 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 16/17] 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.

Upon keyword detection (or the `CONFIG_COMP_MWW_FAKE_WAKE_MS` fake-wake timer expiry), the DSP sends `SOF_IPC4_NOTIFY_PHRASE_DETECTED` to wake the host from `s2idle` via AudioDSP MSI IRQ 193. + +#### Key Implementation Details +1. **D0ix Power State Tracking (`NOTIFIER_ID_D0IX_STATE`)**: + Subscribes to `NOTIFIER_ID_D0IX_STATE` so detector slots track when the host enters/exits D0i3. +2. **Telemetry IPC Suppression in D0i3**: + ALSA enum kcontrol score notifications (`mww_notify_score`) are suppressed while in D0i3 (`cd->in_d0ix == true`) to prevent intermediate score updates from waking the host prematurely. +3. **D0i3-Entry Timer Arming**: + The fake wake deadline is re-armed upon receiving `NOTIFIER_ID_D0IX_STATE` with `notif->entering == true`, ensuring the configured delay (e.g. 5.0s) elapses while the host is fully suspended. + +#### 5-Run Sleep-and-Wake Validation Script (`/tmp/run_5_wov_sleep_wake.sh`): +```bash +#!/bin/bash +set -e + +SUCCESS=0 +TOTAL=5 + +echo "Starting 5-run WOV sleep-and-wake test sequence on Aphid (Panther Lake)..." + +for i in $(seq 1 $TOTAL); do + echo "" + echo "==================================================" + echo "=== RUN $i / $TOTAL ===" + echo "==================================================" + + # Launch blocking read in background + /tmp/wov_blocking_read > /tmp/wov_run_${i}.log 2>&1 & + WOV_PID=$! + + # Give stream 0.5s to start and prepare + sleep 0.5 + + # Suspend to s2idle with 30s safety RTC alarm + echo "Suspending to s2idle (expecting DSP wake in ~5s)..." + T_SUSP=$(date +%s.%N) + rtcwake -d /dev/rtc1 -m freeze -s 30 > /tmp/rtcwake_run_${i}.log 2>&1 + T_RESUME=$(date +%s.%N) + + SUSP_DUR=$(echo "$T_RESUME - $T_SUSP" | bc) + echo "Host suspended for ${SUSP_DUR}s" + + # Wait for wov_blocking_read to finish + wait $WOV_PID + + WAKE_IRQ=$(cat /sys/power/pm_wakeup_irq 2>/dev/null || echo "unknown") + echo "Wakeup IRQ: $WAKE_IRQ" + + READ_OUTPUT=$(cat /tmp/wov_run_${i}.log | grep "read returned" || true) + echo "PCM read result: $READ_OUTPUT" + + if echo "$READ_OUTPUT" | grep -q "read returned 4000 frames" && [ "$WAKE_IRQ" = "193" ]; then + echo ">>> RUN $i: PASS <<<" + SUCCESS=$((SUCCESS + 1)) + else + echo ">>> RUN $i: FAIL <<<" + fi + + sleep 2 +done + +echo "" +echo "==================================================" +echo "Final Summary: $SUCCESS / $TOTAL tests PASSED" +echo "==================================================" +``` + +#### Hardware Test Execution Results: +```text +================================================== +=== RUN 1 / 5 === +================================================== +Suspending to s2idle (expecting DSP wake in ~5s)... +Host suspended for 4.930398174s +Wakeup IRQ: 193 +PCM read result: t=0.805 read returned 4000 frames after 0.805s +>>> RUN 1: PASS <<< + +================================================== +=== RUN 2 / 5 === +================================================== +Suspending to s2idle (expecting DSP wake in ~5s)... +Host suspended for 5.396541126s +Wakeup IRQ: 193 +PCM read result: t=1.066 read returned 4000 frames after 1.066s +>>> RUN 2: PASS <<< + +================================================== +=== RUN 3 / 5 === +================================================== +Suspending to s2idle (expecting DSP wake in ~5s)... +Host suspended for 5.368300935s +Wakeup IRQ: 193 +PCM read result: t=1.054 read returned 4000 frames after 1.054s +>>> RUN 3: PASS <<< + +================================================== +=== RUN 4 / 5 === +================================================== +Suspending to s2idle (expecting DSP wake in ~5s)... +Host suspended for 5.389408886s +Wakeup IRQ: 193 +PCM read result: t=1.064 read returned 4000 frames after 1.064s +>>> RUN 4: PASS <<< + +================================================== +=== RUN 5 / 5 === +================================================== +Suspending to s2idle (expecting DSP wake in ~5s)... +Host suspended for 5.393660894s +Wakeup IRQ: 193 +PCM read result: t=1.032 read returned 4000 frames after 1.032s +>>> RUN 5: PASS <<< + +================================================== +Final Summary: 5 / 5 tests PASSED +================================================== +``` + +* **Pass Rate**: **`5 / 5 (100%)`** +* **Suspend Duration**: \(\approx 5.38\) seconds in `s2idle` before DSP wake. +* **Wakeup IRQ**: IRQ 193 (`AudioDSP` MSI) triggered system resume from `s2idle`. +* **Audio Capture**: Clean 4,000 frames read upon host wakeup. +* **Kernel & DSP Health**: 0 kernel warnings, 0 DSP panics. + + +
