June 2026 monthly summary for sonic-net/sonic-buildimage focused on enhancing thermal management for NH-5010 by updating over-temperature thresholds across multiple sensors. Delivered a single, traceable feature with documented commit and sign-offs. No separate bug fixes recorded this month; work centers on preventive stabilization to improve device reliability and uptime.

May 2026 performance-focused contributions in sonic-buildimage focused on improving runtime efficiency and scalability of the poll_wait path. Delivered a targeted optimization to reduce CPU usage and prevent tight-loop spinning, benefiting the xcvrd workflow and overall system stability. The changes were implemented in NH's pddf_custom_fpga_algo module with a concise, review-ready commit.

Monthly summary for 2026-04: Delivered key NH-5010 network interface enhancements in sonic-buildimage, enabling MSI and NAPI and initializing bcm0/bcm1 at boot to improve network performance and boot-time readiness. The changes include the commit 0262fef541b61a43d0b33715bdce73b8e9fdc265 titled '[Nexthop] Enable msi and napi on NH-5010 (#26206)'. This work reduces interrupt overhead, improves throughput, and sets foundation for future driver optimizations. Sign-offs: Roy Wen; co-authored by Saravanan Sellappa.

March 2026: Focused on NH-5010 platform robustness and test coverage. Delivered a robustness fix for the PDDF PSU driver VOUT_MODE fallback to prevent failures when hardware does not support the requested mode. Completed NH-5010 platform enhancements (Parts 5-6) including 100% disk usage allocation for the root-overlay, xcvr_lpmode settings fix, thermal PID tuning, corrected PSU EEPROM driver usage, and DPM/DCDC version tracking; added CMIS support and EEPROM prioritization, plus extra debug scripts and miscellaneous improvements. Expanded sonic-mgmt chassis API tests to validate multiple vendor extension TLVs for system EEPROM information. Addressed initialization and debugging gaps by fixing a thermalctld KeyError and reducing recirc port warnings in nh-led-control. Overall, these changes improve platform stability, vendor interoperability, and deploy readiness, delivering tangible business value through higher reliability, reduced field fixes, and faster NH-5010 onboarding.

February 2026 monthly summary for sonic-buildimage: Delivered NH-5010 Platform Support Enhancement, incorporating FEC configuration updates, FIPS enablement, sensor threshold adjustments, and ASIC device ID reflection across configuration files; enhanced boot stability with PMON start-limit tuning; merged changes via PR 25177.

January 2026: Delivered two targeted updates in sonic-buildimage with clear traceability to commits. The FPGA CLI now robustly supports Click 8.0, including type checks for integer and tuple inputs. Enhanced thermal management capabilities through PddfAsicThermal and PddfChassis changes, enabling accurate position tracking via a new offset parameter and proper propagation through construction.

December 2025 monthly summary for sonic-buildimage: Delivered NH-5010 Platform Compatibility Enhancement enabling broader NH-5010 support with thermal compatibility updates, port alias adjustments, and removal of outdated test cases to streamline the codebase. The change set includes updates to nh-4010 for thermal changes and removal of nh-4220 test cases, as reflected in commit be886c08bc714dc20039ff0cf4565158c8b97f86 ([Nexthop] NH-5010 Platform Support [Part 2]).

Month: 2025-10 — Focused on enabling NH-5010 platform support in sonic-buildimage, with targeted stability improvements, pipeline cleanups, and test updates to ensure smooth onboarding of new hardware. Key outcomes include delivery of device directory scaffolding, enhancements to sonic-platform-modules-nexthop, and alignment of build/test artifacts with NH-5010 requirements. This work lays groundwork for robust hardware support, reduces onboarding time for new platforms, and demonstrates strong collaboration across teams.
