PROFILE
Kai Liang
Over a two-month period, contributed to the zephyrproject-rtos/trusted-firmware-a repository by developing foundational CPU power management features for the MT8196 platform. Delivered a centralized power management framework, including modules for CPC, MCDI idle-state handling, MCUSYS, and PWR_CTRL, all implemented in C with Makefile integration. This work enabled fine-grained control over CPU power states, improving energy efficiency and platform performance. Subsequently, introduced a CPU Power Topology Module that established structured power-domain coordination and topology initialization, supporting scalable configurations through new headers and build rules. Focused on embedded systems, ARM architecture, and low-level programming, the work strengthened platform power management readiness.

Dec 1, 20242024-12 monthly summary for trusted-firmware-a: Delivered MT8196 CPU Power Management Framework, consolidating CPU power management across the MT8196 platform with CPC (centralized power control), an MCDI idle-state driver, MCUSYS power management modules, and a dedicated PWR_CTRL module. This enables finer-grained CPU power state management, improving energy efficiency and platform performance. No additional major bug fixes reported within this scope. Demonstrated technologies include kernel driver development in C, power management subsystems, and modular software architecture. Business impact: reduced energy consumption, improved battery life and performance consistency on MT8196 deployments, and a solid foundation for dynamic power optimization across workloads.
