PROFILE
Sung-hun Kim
Sfoon Kim focused on enhancing profiling reliability for RISC-V64 systems within the google/perfetto repository. Addressing a persistent stack unwinding failure, Sfoon analyzed the RISC-V64 calling conventions and adjusted stack pointer retrieval logic in C and C++ to align with architectural requirements. This targeted fix improved the completeness and accuracy of profiling data, reducing the need for post-processing corrections and supporting more robust cross-architecture profiling. Drawing on expertise in compiler internals, debugging, and performance profiling, Sfoon’s work demonstrated a deep understanding of system programming and contributed to sustained platform support for RISC-V64 within the perfetto codebase.
