PROFILE

Wenbo Hou

Wenbo Hou focused on stabilizing and enhancing low-level firmware and input handling in the microsoft/mu_plus and microsoft/mu_basecore repositories over a four-month period. He addressed complex bugs in event handling, keyboard LED synchronization, and touchscreen HID reporting, using C and Rust to improve reliability across embedded systems and UEFI environments. His work included refining input method switching between touch and keyboard, ensuring accurate LED state initialization during boot, and preventing division-by-zero errors in touchscreen drivers. By validating recovery paths in the Fault Tolerant Write module, Wenbo strengthened firmware update resilience, demonstrating depth in driver development, firmware integration, and robust debugging.

May 2025 performance summary for microsoft/mu_basecore: Strengthened FTW recovery robustness in the variable store by validating FtwWorkSpaceHeader and enabling recovery from a spare block. This reduces recovery failures when the primary FTW store is erased or corrupted and improves resilience of firmware update/restore paths. The work was implemented via a cherry-picked patch to MdeModulePkg FaultTolerantWriteDxe with commit 4b640d6c142650824dc8a3dd38ec55597b26d2dd.
