Thanks @lgirdwood will have a look! |

@lgirdwood this looks very promising tested the ARM SIMD instructions on imx8mp with M7 core, looks like the load for simple volume pipeline decreased by at least 30%. Also, looking to borrow an RT to do some more testing. |

Pls rebase as sof static pipeline support is now upstream, we need to use teh upstream infra.

pls make sure this aligns with recent commits like 1fe1b8c for size_t and int usage.

This commit is too large, all the zephyr changes should go to zephyr, this can go to my fork atm and be referenced viw a local west url in this pr.

the tooling should go into sof-utils
… unsigned int Align drc_arm.c helper signatures and local loop/index variables with commit 1fe1b8c ("audio: drc: use size_t for byte, sample and frame counts"): - Use size_t for byte, division frame, and loop indices (nbyte, div_start, count, i, j, inc). - Use unsigned int for channel counts and indices (nch, ch). - Use bool for boolean flags (is_release, is_releasing, is_bad_db, is_2byte).

… builds Allow CONFIG_SOF_FULL_ZEPHYR_APPLICATION targets without CONFIG_USERSPACE (such as single-core ARM Cortex-M microcontrollers) to build cleanly: - Guard generated <zephyr/syscalls/*.h> includes with CONFIG_USERSPACE and map syscall wrappers directly to z_impl_* functions when userspace is disabled. - Set Cortex-M cache line fallback alignment to 32 bytes in rtos/cache.h while preserving 64 bytes for host/POSIX library builds. - Ensure generated sof_versions.h and uuid-registry.h are created and added to include paths before building SOF subdirectories and app. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
Wire up NXP i.MX SAI, S/PDIF, ESAI, and MICFIL DAI types in IPC4/IPC3 DAI lookup and DMA device mapping so Zephyr-based NXP i.MX / i.MX RT platforms can instantiate SAI and S/PDIF Copiers in IPC4 pipelines. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
…ine capture - Add CONFIG_ZEPHYR_DOMAIN_AUDIO_TIMER to drive the Zephyr LL scheduling domain directly from hardware DAI DMA period completion callbacks while suppressing SysTick k_timer ticks when audio is active. - Scope eDMA source/destination address increment setup in dai-zephyr.c to NXP i.MX DAI types. - Allow DAI component state transitions in dai_comp_trigger_internal() when CONFIG_STATIC_PIPELINE is enabled alongside IPC4. - Pass (dma_fmt, local_fmt) instead of (local_fmt, dma_fmt) to pcm_get_conversion_function() for capture streams in set_new_local_buffer(). - Reset static pipelines cleanly on XRUN recovery when host IPC stream structures are absent. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
…ipeline bridge - Add the COMP_USB_AUDIO host endpoint component with lock-free SPSC playback/capture ring buffers and asynchronous USB SOF-to-DAI rate estimation for explicit UAC2 feedback. - Extend upstream static_pipeline_uac2.c to bridge Zephyr UAC2 callbacks with COMP_USB_AUDIO ring buffers, support zero-copy UAC2 capture double- buffer replenishment via static_pipeline_uac2_buf_release(), and query the playback rate adjustment for USB feedback.

Add Sound Open Firmware platform and board support for PJRC Teensy 4.1
(NXP i.MX RT1062 Cortex-M7 @ 600 MHz):
- src/platform/teensy41/: pure SOF platform initialization, clocks, memory
layout, and upstream static_pipeline descriptor graph (USB Audio <->
Volume <-> S/PDIF or SAI1 I2S Copier).
- zephyr/lib/{alloc.c,dma.c}: static SOF heap and eDMA0 registration.
- app/boards/teensy41.{conf,overlay} & app/src/: Zephyr UAC2 composite
device initialization, HalfKay bootloader soft-reboot request (0xFB),
and upstream static_pipeline startup.

Summary
Adds Sound Open Firmware (SOF) platform and USB Audio Class 2.0 (UAC2) bridge support for PJRC Teensy 4.1 (
NXP i.MX RT1062Cortex-M7 @ 600 MHz), built directly on top of upstream SOFstatic_pipelineinfrastructure (CONFIG_STATIC_PIPELINE,CONFIG_STATIC_PIPELINE_UAC2) and ARM Cortex-M SIMD optimizations.Review Updates
