2026-03 monthly summary for facebook/OpenBIC: delivered a critical reliability improvement in the OpenBIC KCS driver by fixing OEM POST command handling. Corrected NetFn OEM request comparison by applying a left shift (NETFN_OEM_REQ << 2) in the comparison, ensuring proper detection of OEM POST Start/End commands and returning the correct completion code to the host, thus preventing BIOS retries. The patch was implemented in the KCS input buffer handling and validated on the Yv4-sd platform with mfg-tool logs showing expected Host7 lifecycle events. Result: reduced BIOS retry churn, shorter POST latency, and improved host-to-BIC reliability. Demonstrated low-level driver debugging, NetFn protocol handling, and end-to-end hardware validation; collaboration with Pat Lin (Co-authored-by).
