PROFILE
Lioraguo-wiwynn
Liora Guo developed and maintained firmware for the facebook/OpenBIC repository, focusing on platform reliability, version control, and hardware integration across Sentinel Dome and Wailua Falls BIC platforms. She implemented VR fault clearance and event logging using C and I2C communication, enabling robust fault recovery after power cycling. Liora enhanced firmware versioning processes, ensuring traceable, reproducible releases by updating macros and headers to align with weekly cycles. She also improved system observability by refining interrupt handling and GPIO management, reducing false alerts during power transitions. Her work demonstrated depth in embedded systems, balancing hardware interaction with disciplined release governance and debugging instrumentation.

Feb 1, 2026February 2026 — Reliability and observability improvements for facebook/OpenBIC. Delivered two targeted items: (1) Platform-specific VR sensor access control to prevent false MB_VR alerts during DC power transitions via a GC2-ES vr_access override that polls VR data only after DC power is confirmed on. Commits include 86de62d8be089e888ee1f9003d4fdc20e643c086 with PR #2663. (2) Enhanced SMI interrupt handling for GPIO stuck-low detection: introduced an SMI GPIO interrupt handler that monitors IRQ_SMI_ACTIVE_BMC_N and starts a 90-second timer; if the GPIO remains low, BIC reports an SMI event to the BMC, and deassertion is also reported. Commit c15ec9aa7ed140f27336c8d3f89c330bc620bcdc with PR #2670. These changes reduce false sensor events, improve debugging visibility, and enhance power-state robustness across DC transitions and SMI scenarios.

Sep 1, 2025September 2025 focused on correcting firmware versioning headers for the OpenBIC components Sentinel Dome (sd) and Wailua Falls (wf) to align BIC_FW_WEEK with the 2025 weekly release cycle. Updated version header macros to reflect 2025.36.01 and the 39th week of 2025 across sd/wf, fixing incorrect BIC_FW_WEEK values and ensuring consistent versioning in downstream builds. This work improves build reproducibility, prevents release-header drift, and reduces customer-facing patch risk.

Apr 1, 2025April 2025 - OpenBIC (facebook/OpenBIC): Implemented a VR fault clearance mechanism to improve stability across AC slot cycles. The change adds plat_pldm_sensor_clear_vr_fault to clear VR fault bits via I2C after slot AC cycling, ensuring the VR fault state is reset after power cycling and enabling faster recovery. This work is tracked by commit 657b72dd35ce73407bd4bf514db7d46a23d40d37 (#2321). No major bugs fixed in this scope. Business value: higher reliability during power cycling, reduced field downtime, and clearer fault visibility.
