During this period, work focused on enhancing the geerlingguy/linux repository with three kernel and driver features targeting video output and memory management for embedded systems. Using C and Device Tree, the developer implemented 60fps interlaced support and timing corrections for the rp1-vec video driver, improving video quality and reliability. They refactored the BCM2712 IOMMU driver to support on-demand translation table allocation and configurable aperture properties, optimizing resource utilization. Additionally, they expanded the IOVA aperture for IOMMU2 to 4GB and introduced PCIe2 QoS map configuration, enabling better throughput and quality of service for high-resolution camera pipelines in Linux environments.
