PROFILE
Sri Latha Ayyannagari
SriLatha Ayyannagari enhanced hardware observability and error diagnostics in the Xilinx/XRT repository by developing and refining context health data reporting for hardware-accelerated workflows. She expanded and cleaned up C and C++ data structures to capture detailed runtime health information, introduced robust error handling for diverse hardware configurations, and standardized naming for maintainability. Her work included implementing new diagnostic fields, improving error message clarity, and validating health data integrity, which collectively reduced troubleshooting time and improved reliability. Leveraging skills in embedded systems, driver development, and runtime APIs, SriLatha delivered targeted, maintainable solutions that deepened diagnostic capabilities across multiple NPU generations.

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.
