PROFILE
Gordon-nexthop
Worked on the sonic-net/sonic-buildimage repository to deliver hardware enablement and configuration enhancements for next-generation networking devices. Over three months, developed features including expanded YANG model support for 1.6T port speeds, NH-4220 platform integration, and dynamic PMBus PSU management for multi-PSU systems. Leveraged C, JSON, and YAML to implement device configuration, data modeling, and driver development, focusing on robust I2C communication and safe code practices. The work enabled seamless hardware upgrades, improved compatibility with new platforms, and scalable power management, providing customers with flexible deployment options and aligning configuration models with evolving hardware requirements in embedded networking environments.

Jan 1, 2026Month 2026-01: Delivered Dynamic PMBus PSU support for sonic-buildimage, enabling an arbitrary number of PMBus-compliant PSUs per device with dynamic fan speed management. Implemented driver enhancements to dynamically determine PMBus block data length and expanded coverage with Nexthop examples for multi-PSU configurations. Achieved code quality and safety improvements including semgrep conformance, removal of attr_len constraints for PSU attributes, and refactoring to use strscpy instead of strncpy. Result: improved hardware compatibility for multi-PSU deployments, more reliable PMBus interactions, and clearer guidance for customers deploying larger PSU configurations.

Oct 1, 2025Monthly summary for 2025-10 focused on sonic-buildimage repository work. Delivered a key capability expansion by updating the YANG model to support higher port speeds, aligning with next-generation hardware roadmaps. The change increases the maximum supported speed for the port speed leaf and the port-speed union from 800 Gbps to 1600 Gbps, enabling 1.6T port configurations and smoother upgrades for customers. The work was implemented in a single core commit and integrated into the sonic-buildimage repo for immediate enablement in deployments.
