PROFILE
Sri Latha Ayyannagari
Over six months, contributed to the Xilinx/XRT repository by developing and refining diagnostic and runtime features for hardware-accelerated workflows. Focused on enhancing error handling and observability, this work included expanding context health data structures, improving runtime diagnostics, and introducing dynamic configuration for emulation environments. Leveraged C and C++ to implement robust data structures, cross-platform compatibility, and targeted error reporting, while maintaining code clarity through refactoring and documentation updates. Addressed both feature development and bug fixes, ensuring reliability across diverse hardware configurations. The engineering approach emphasized maintainability, traceability, and alignment with repository standards, resulting in more actionable diagnostics and streamlined debugging.

Dec 1, 2025In December 2025, delivered a dynamic DDR offset configuration feature for the Xilinx/XRT emulation environment, improving flexibility and cross-platform reliability. Implemented an environment variable-based approach to determine the DDR offset for the emulation device, complemented by comments improvements and Windows build issue resolution to ensure stable, maintainable emulation workflows. These changes enable more accurate emulation scenarios, faster testing cycles, and reduced platform-specific build regressions.

Oct 1, 2025Delivered context health data reporting for AIE4/AIE2PS NPUs in XRT, introducing new data structures and enums, enhanced V1 health reporting with detailed AIE2/AIE4 context information, and added ERT_START_DPU opcode handling. Standardized naming by renaming uc_health_info to ert_uc_health_info for consistency across the codebase. These changes improve observability, error diagnosability, and cross-generation support.

Aug 1, 2025Monthly summary for 2025-08 focusing on Xilinx/XRT deliverables, stability, and impact. Highlights include delivered feature cleanup to simplify health data handling and improved runtime robustness for non-ELF flow across hardware configurations. These efforts reduce maintenance costs, lower risk of misreported health data, and improve reliability on DPU/NPU deployments. The work demonstrates careful refactoring, stronger error handling, and adherence to commit traceability between related components.

Jul 1, 2025July 2025 monthly summary for Xilinx/XRT focusing on observability and runtime diagnostics. Implemented Enhanced Runtime Diagnostics by expanding ert_ctx_health_data to capture new fields (exception types, program counters, and application module details) and updated error message formatting to include these fields. This delivers richer diagnostic context for timeouts and fatal errors, accelerating root-cause analysis and reducing debugging effort for runtime issues. No major bug fixes were filed this month in the XRT scope, with all work tied to this diagnostic enhancement.
