Month: May 2026 – Zephyr AMD ACP TDM support delivered. Delivered TDM DAI driver for AMD Audio Co-Processor 7.0 with I2S format, including ACP 7.0 register definitions, device-tree bindings, and build integration (Kconfig/CMake). Also delivered TDM DMA driver for ACP 7.0, enabling memory-to-device and device-to-memory transfers, with associated device-tree node and build integration. No major bugs recorded for this scope; work emphasizes feature delivery and hardware enablement. Overall impact: Enables Zephyr-based audio paths for AMD ACP 7.0 TDM, expanding hardware support, reducing OEM integration effort, and laying groundwork for future performance enhancements in audio capture/playback. Technologies/skills demonstrated: kernel driver development (DAI and DMA), I2S/TDM, device-tree bindings, kernel build integration (Kconfig/CMake), collaboration and clear commit documentation.

April 2026 monthly summary for thesofproject/sof highlighting targeted feature delivery and platform readiness improvements. This period focused on enabling SOF ACP 7.0 platform support by aligning the Zephyr RTOS integration with native ACP 7.0 drivers. The changes are captured in a single, well-documented commit and associated West/YAML revision update.

March 2026 monthly summary for zephyrproject-rtos/zephyr focused on enabling AMD ACP 7.0 support for Xtensa HiFi5. Delivered comprehensive SoC and board definitions along with essential build artifacts (defconfig, Kconfig options, linker script, and register/memory headers) to bring up ACP 7.0 DSP on supported hardware. Work is tied to commit fbfa44d8f40ae1c792bb5f566bbf353450d5e53f and reflects a strong feature bring-up with clear future integration paths. No separate bug fixes were documented for this month; the primary effort was feature development and integration groundwork.

February 2026: Delivered end-to-end AMD ACP platform integration across two repositories (thesofproject/sof and zephyrproject-rtos/zephyr). Implemented ACP 7.0 native Zephyr support with SoundWire DAI, platform/build/config cleanups, and Xtensa/defconfig refinements; added ACP 6.0 non-native Zephyr support with alignment changes. Also delivered AMD ACP 7.0 DSP hardware integration in Zephyr (device tree, DMA/SDW DMA, interrupt controller, and SoundWire DAI) and completed board defconfig alignment for ACP 6.0. These changes reduce integration effort, accelerate deployment, and improve audio reliability in Zephyr environments. Technologies demonstrated include Zephyr RTOS integration, SoundWire and DAI driver development, DMA and interrupt controller tooling, device-tree bindings, and cross-repo collaboration.

May 2025 monthly summary for zephyrproject-rtos/sdk-ng: Delivered Xtensa AMD-ACP AdSP Zephyr-ELF Architecture Support with architecture-specific configurations and extensive opcode decoding; no major bugs fixed. Focused on delivering business value and technical readiness for Zephyr on AMD-ACP platforms.
