Baiqiaosen contributed to the arceos-hypervisor/arceos repository by developing two core features over two months, focusing on system-level enhancements in Rust. He improved SMP task scheduling and CPU ID management, refactoring the codebase to enable conditional multi-processor features and streamline atomic operations for clarity and efficiency. In addition, he designed and integrated ext4 filesystem support, creating an ext4fs module and connecting it with existing storage abstractions to enable mounting and interaction with ext4-formatted devices. His work demonstrated depth in concurrency, embedded systems, and filesystem development, delivering maintainable, well-integrated solutions that broadened storage interoperability and system reliability.

Sep 1, 20252025-09 Monthly Summary: Ext4 filesystem support delivered for the arceos hypervisor, enabling mounting and interaction with ext4-formatted storage devices. Implemented an ext4fs module and integrated it with existing components (axfs and axfeat). Added concrete implementations: Ext4FileSystem and FileWrapper, enabling seamless access to ext4 storage across the virtualization stack. Updated dependencies to support ext4 integration and groundwork for further FS features. Key business value: broadens storage interoperability, enabling customers to deploy widely-used Linux file systems on virtual environments with minimal configuration. This reduces friction for new deployments and opens up new use-case opportunities (e.g., standard Linux VMs and container storage backends) while aligning with roadmap goals for filesystem versatility and reliability. Overall accomplishments: Delivered a cohesive FS extension end-to-end, including module design, API integration, and dependency management. Demonstrated careful coordination with existing storage abstractions (axfs, axfeat) and adherence to the project’s conventions for versioned commits and maintainability. Note: No critical bug fixes reported this month; focus was on feature delivery and code quality, setting the stage for future enhancements (e.g., performance tuning, advanced ext4 features).
