Oct 1, 2025Monthly summary for 2025-10 focusing on stabilizing hardware control interfaces in facebook/fboss. Key work included LED bug fixes in BSP 3.4.0 with platform_manager.json version updates, and enabling user-space MDIO C45 transactions by introducing MDIO data types in fbiob-ioctl.h. These changes improve hardware reliability, enable richer user-space control, and align with the BSP roadmap.

May 1, 2025May 2025 performance summary for facebook/fboss: Focused on Darwin-specific BSP integration and governance changes to support a BSP-based migration path. Key outcomes include a BSP version upgrade and access-control hardening in Darwin configuration to enable a safe BSP migration. By upgrading BSP to pull latest Darwin fixes and restricting access to SCD transceiver control registers until the CSPqs bsp migration completes, the work reduces production risk, improves stability, and sets up a clear path for ongoing BSP adoption.
