June 2026 monthly summary for sonic-buildimage focusing on device compatibility and stable link bring-up. Key activities include cleaning up legacy Ethernet configuration to fix device compatibility across Nokia-IXR7220-H6-O256 and H6-P128, and adding per-port TX FIR coefficients and input-EQ targets for the H6-128 to enable reliable 100G links. Both changes achieved Azure CI green across impacted areas and received design approvals, reducing test fragility and accelerating integration.

In April 2026, expanded hardware SKU validation in sonic-net/sonic-utilities by adding Nokia TH6 HWSKUs support to GCU field operation validators. Implemented a new TH6 ASIC entry (Nokia-IXR7220-H6-64, -P128, -O256) and accompanying unit tests for validation and name-resolution. This work strengthens validation coverage for Nokia TH6 devices, reducing field incidents and accelerating onboarding for new HW SKUs. The changes align with generic_config_updater workflow to ensure maintainability and future scalability. Tech stack: Python, unit testing, Broadcom ASIC mapping, GCU validator framework.

April 2025: Nokia ASIC platform detection test coverage added for get_asic_name in sonic-utilities, covering Nokia platforms (th3/th4/th5/td4/j2c+/q2c+) by mocking subprocess.Popen and sonic_py_common.device_info.get_sonic_version_info. This work, tied to commit ed1ab68f976092c96bb8f02bb0490191e7be47e1, enhances platform detection accuracy, improves QA coverage, and reduces downstream issues in Nokia devices.
