Developed and integrated System Companion Processor (SCP) firmware for the MediaTek MT8189 SoC within the NVIDIA/linux-firmware repository, enabling hardware-accelerated video encoding and decoding through a RISC-V SCP. Focused on firmware development using binary languages, the work established a robust packaging and loading path for SCP firmware, laying the groundwork for future enhancements. This integration offloaded media processing tasks from the main CPU, reducing power consumption and improving system responsiveness on MT8189-based platforms. The contribution provided a technical foundation for future SCP-based features, emphasizing efficient firmware delivery and maintainability within the existing Linux firmware infrastructure for MediaTek devices.
