PROFILE
Richard_kuo
Over three months, this developer enhanced thermal management and fan control across the edge-core/sonic-buildimage repository, focusing on cross-platform reliability and precision. They delivered a dynamic fan speed tolerance feature, refactored platform-specific control logic, and introduced configurable thresholds to improve system stability under varying thermal policies. Using C and Python, they implemented robust state-change detection based on fan telemetry, resolving issues where manual adjustments blocked policy updates. Their work included firmware-level duty cycle calculations, device driver refinements, and dynamic attribute handling for per-fan thresholds, resulting in more accurate, scalable, and maintainable backend systems for embedded hardware environments.

Jan 1, 2026January 2026 (2026-01) focused on stabilizing thermal policy behavior in edge-core/sonic-buildimage. Implemented fan-speed-based state-change detection to replace reliance on the policy state, addressing issues where manual fan-speed adjustments prevented policy updates and improving reliability across platform modules. This change delivers more robust thermal policy updates and smoother platform integration, reducing operational risk and support overhead.

Dec 1, 2025December 2025 monthly summary for edge-core/sonic-buildimage focused on delivering a cross-platform thermal management enhancement: Dynamic Fan Speed Tolerance under Thermal Policy. The work introduces a configurable tolerance flag for fan speed adjustments, updates fan control logic across platforms to dynamically adjust speeds while respecting tolerances, and improves system stability and predictability under thermal changes. The changes are anchored to JIRA-ONSBUSWI-3489 and implemented through a feature commit that refactors platform-specific fan control paths, uses get_target_speed() to compute ori_duty_cycle, and adds a platform-name helper and a dedicated fan activation pathway.
