During February 2025, work focused on enhancing RISC-V capability detection within the openssl/openssl repository. The developer delivered a feature that integrated dl_hwcap to improve detection of ZVK* vector instruction features, enabling more accurate runtime hardware capability reporting for RISC-V architectures. This involved implementing new definitions and logic in C to determine vector instruction availability, supporting optimized code paths in OpenSSL builds. The approach demonstrated skills in embedded systems, low-level programming, and system programming, with attention to cross-architecture testing. No major bugs were addressed during this period, as efforts concentrated on expanding feature detection and hardware reporting functionality.
