PROFILE
Nick Hollinghurst
Nick Hollinghurst enhanced the geerlingguy/linux repository by developing and refining Linux kernel drivers for video hardware and memory management. He implemented 60fps interlaced support in the rp1-vec driver, introducing field-based buffer flips via interrupt service routines and correcting timing issues to improve video fidelity. For the BCM2712 IOMMU, Nick refactored translation table allocation to be on-demand and added Device Tree properties for flexible aperture configuration, optimizing resource use. He also expanded the IOVA aperture for IOMMU2 and configured PCIe2 QoS mapping, supporting higher-resolution camera pipelines. His work leveraged C, Device Tree, and embedded systems expertise for robust subsystem improvements.
