Worked on the ROCm/rocm-systems repository to deliver a runtime trap handler feature and a critical bug fix over a two-month period. Updated the second-level trap handler in Assembly and C++ to maintain ABI compatibility with ROCr-runtime, removed unsupported architecture-specific code, and ensured accurate debugger communication by patching the r_debug structure. Addressed a porting regression in gfx11 trap handling by correcting s_trap detection logic, restoring stability for GPU workloads. Demonstrated expertise in low-level programming, debugging, and driver development, with careful attention to code quality, traceability, and maintainability throughout the process to improve runtime reliability and cross-platform support.

Apr 1, 2025April 2025 (2025-04) monthly summary for ROCm/rocm-systems: Delivered the ROCr-runtime Trap Handler ABI Compatibility and Debugger Communication feature. Updated the second-level trap handler to align with ROCr-runtime changes, maintained trap handler ABI version, removed unsupported architecture-specific parts, and patched the r_debug structure to ensure the debugger sees the correct ABI version. The change is traced to SWDEV-517078 and commit 7b72c1b7868d5f992fb562bd30db49225caacab2. This work enhances runtime stability, improves cross-debugger compatibility, and reduces maintenance risk across ROCm platforms.
