Delivered DMA test configuration overlays for the tt-blackhole platform within tenstorrent/tt-zephyr-platforms, enabling upstream DMA tests and configurable DMA channels across scenarios. Added YAML-based configurations and overlay files to support comprehensive DMA validation and upstream readiness, accelerating feedback loops and test coverage.

August 2025 monthly performance summary for tenstorrent/tt-zephyr-platforms. Delivered key platform improvements that enhance boot-time interaction, improve PCIe scanning robustness, and expand firmware power-configuration support. Work focused on aligning components with the new bootfs APIs and adopting efficient directory traversal patterns to improve maintainability and reliability, while removing configuration bottlenecks for higher-performance runs.

July 2025 performance summary: Delivered critical thread-safety fix for the bh_fwtable pseudo-driver and modernized the TT Boot FS API to a stateless design, complemented by expanded testing and device-tree updates. These changes improve boot reliability, enable independent calls to boot filesystem operations, and broaden validation coverage across TT hardware configurations. The work enhances maintainability and reduces risk in production deployments across the tenstorrent/tt-zephyr-platforms stack.

June 2025 highlights: key deliverables span AmbiqMicro/ambiqzephyr and tenstorrent/tt-zephyr-platforms, focusing on reliability, platform readiness, and end-to-end firmware-table support. A critical bug fix ensured correct overflow handling for unsigned accumulators in strtoll, preventing potential data corruption. In parallel, the Tenstorrent Blackhole fwtable feature progressed from concept to a complete integration in Zephyr with a DTS binding, a dedicated fwtable driver, device-tree integration, and tests. The work also includes modernization of the fwtable API by migrating to the new device driver model.
