PROFILE
Guangjie Song
Guangjie Song developed foundational power management drivers for the zephyrproject-rtos/trusted-firmware-a repository, focusing on the MT8196 platform. Over two months, Guangjie implemented a Dynamic Clock Management driver that dynamically slows or gates clocks during CPU and bus idle states, reducing idle power consumption while maintaining active performance. He also delivered an MTCMOS driver enabling safe, configurable power sequencing for UFS and its PHY, including bus protection and state acknowledgment routines. Working primarily in C and Makefile, Guangjie applied expertise in driver development, embedded systems, and low-level programming to enhance baseline power efficiency and reliability in the trusted firmware stack.
