Mar 1, 2026

March 2026 performance-focused delivery for nxp-upstream/zephyr. Implemented an optimization in the kernel work queue to stop yielding when the current work queue is empty, reducing unnecessary scheduling overhead and wakeups. This change improves scheduling efficiency and CPU utilization during low-workload periods, enhancing latency and throughput for queued tasks while preserving correctness. The change was committed in the Zephyr repository as f75db68d03f1050e47ecb5a647875a81b62c9bab.

Dec 1, 2025

December 2025 monthly summary: Delivered NXP Wi‑Fi support for custom host platforms across two repositories, enabling configurable builds and broader hardware compatibility. Implemented and validated the CONFIG_NXP_WIFI_CUSTOM_HOST option, updated HAL NXP revisions to support custom host integration, and resolved a build issue to enable Wi‑Fi/BLE on custom host platforms. This work increases platform coverage, reduces integration time for customers, and provides a more maintainable, configurable build pipeline across the Zephyr-based SDK and HAL layers.

Nov 1, 2025

November 2025: Delivered UDP Upload Clock Compensation feature in nrfconnect/sdk-zephyr to improve timing accuracy when system clock precision is below 1 kHz. Implemented a tick-based compensation mechanism that computes the actual versus expected packet counts every 10 ticks and adjusts delay ticks to align throughput with targets. Safeguards prevent negative delays and roll compensation into the next period; if compensation sums exceed practical bounds, adjustments are disabled for remaining traffic. This change increases UDP throughput reliability and measurement accuracy in low-clock environments, benefiting real-time data transfer and performance benchmarks.
