PROFILE
Roman Mazurak
Worked on the zephyrproject-rtos/trusted-firmware-m repository to enhance FPU context management for ARMv8m main architecture, focusing on partition safety and reliable FPU state preservation during context switches and FLIH mode interrupts. Addressed a potential MemManage fault by ensuring lazy stacked FPU registers are flushed before partition boundary switches, reducing the risk of faults during interrupt handling. Implemented these changes in C, leveraging expertise in ARM architecture, embedded systems, and low-level programming. Delivered maintainable and auditable firmware improvements that support multi-partition workloads, with clear commit traceability and a focus on robust interrupt handling and extended FPU state management across contexts.
