Jan 1, 2026January 2026 (2026-01) monthly summary for facebook/fboss: Delivered two platform-level configuration enhancements to improve BSP compatibility and DVT readiness. Key changes include a BSP kernel modules compatibility upgrade and an SMB versionedSensors update for DVT, with preloading of the fboss_iob_i2c driver to address timing issues. All changes underwent standard validation (linting, JSON validation, and test plans) and passed platform-wide checks on platform_manager and sensor_service. Impact highlights: - Ensured compatibility with BSP 4.0.0-1, reducing risk of ABI/module mismatches and accelerating BSP upgrade readiness. - Introduced SMB versionedSensors v2 3 10 for DVT, expanding hardware coverage and preloading critical driver to prevent startup timing issues, shortening validation cycles. - Improved reliability and stability of the SMB path during device bring-up and testing. Technologies/skills demonstrated: embedded Linux packaging and config management, BSP/kernel module versioning, I2C driver handling, JSON/YAML platform configurations, pre-commit linting, test automation, and cross-team PR integration.

Nov 1, 2025November 2025 development summary for fboss: Key features delivered: - Sensor version 4.2.1 support and enhanced thermal monitoring for the COME sensor: added configuration for v4.2.1, initialization settings for PMBus power bricks, renamed MCB_PU1066_LTC4287_P48V_POUT to MCB_PU1066_LTC4287_P48V_PIN for clarity, and updated platform_manager.json/sensor_service.json accordingly. - Thermal management enhancements: TMP432 high limit raised to 100°C; added new fan RPM thresholds (FAN1-4) and updated related sensor thresholds (SMB_TH6 sensors and COME_inlet/outlet temps). Major bugs fixed: - PMBus driver load failure on new power bricks caused by PMBus page register change; fixed by applying explicit initRegSettings to set PMBus page to 0 during initialization across EVT devices. - Strengthened validation across COME v4.2.1 and v4.2.2 with updated test logs and success checks. Overall impact and accomplishments: - Higher reliability of thermal and power monitoring across hardware revisions; reduced risk of thermal shutdown; easier onboarding of hardware variants. - Improved maintainability through consistent naming and JSON configuration in platform_manager.json and sensor_service.json. Technologies/skills demonstrated: - PMBus initialization and configuration, TMP432 sensor management, thermal design thresholds, JSON config management, hardware validation and testing. Business value: - Reduces thermal-related outages, improves visibility into power and ASIC temperatures, and accelerates deployment of sensor revisions with fewer code changes.
