Sri Latha Ayyannagari enhanced the Xilinx/XRT repository by developing advanced runtime diagnostics and context health data reporting for hardware-accelerated workflows. She introduced new C and C++ data structures and enums to capture detailed health metrics, expanded error handling for AIE and DPU/NPU flows, and implemented environment-variable-driven configuration for emulation devices. Her work included targeted code refactoring, improved cross-platform compatibility, and robust validation guards to prevent processing malformed data. By focusing on embedded systems, driver development, and runtime API design, Sri Latha delivered features that improved observability, reduced troubleshooting time, and increased reliability across diverse hardware and software environments.
In 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.

Delivered 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.

Monthly 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.

July 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.
