Developed the Boot Argument Access API for the arceos-hypervisor/arceos repository, focusing on early access to boot-time device tree blob addresses during system initialization. Leveraged Rust to implement the get_bootarg interface, utilizing a LazyInit storage pattern to support early initialization flows within the hypervisor boot sequence. This approach reduced friction in boot-time debugging and established a foundation for future enhancements to the boot process. The work centralized boot argument access, improving code maintainability and enabling faster configuration during startup. Demonstrated expertise in embedded systems, low-level development, and system programming, with a feature-focused delivery and no externally reported critical bugs.
