Worked on the ROCm/rocm-systems repository to improve reliability and correctness in kernel parameter handling for system programming tasks. Focused on driver development using C++ and low-level programming techniques, the main contribution involved strengthening error handling within the KernelParameters::capture path. By ensuring that the absence of a device sampler now returns CL_INVALID_CONTEXT, the update prevents invalid kernel parameter capture and mitigates potential downstream failures during kernel launches. This targeted bug fix enhances overall system stability and aligns with established ROCm code quality practices, demonstrating a careful, defensive approach to error handling and clear commit traceability throughout the development process.
