PROFILE
Yong Wu
Worked on the zephyrproject-rtos/trusted-firmware-a repository to deliver a power-managed SMMU driver for the MT8196 platform, focusing on robust power domain access for both Multimedia and APU SMMUs. Implemented reference counting to coordinate power management commands from Linux (EL1) and the hypervisor (EL2), ensuring efficient resource handling. Addressed build system continuity by adding stub implementations for the Mediatek MMinfra driver, allowing builds to complete even when prebuilt libraries were unavailable. Utilized C and Makefile expertise alongside skills in embedded systems and driver development to remove integration blockers and support platform bring-up readiness for Trusted Firmware A on MT8196.
