Omar Elfouly
Contributed to the google/perfetto repository by developing and standardizing memory analysis workflows, enhancing trace symbolization, and improving CI infrastructure. Over three months, migrated memory snapshot tables to the Perfetto SQL standard library, integrated the LLVM symbolizer for richer debugging, and expanded Electronic Trace Macrocell (ETM) support for more accurate trace processing and visualization. Leveraged C++, Python, and SQL to implement dynamic linking, build system safeguards, and new SQL functions, while refining test automation and profiling tools. These efforts improved data quality, debugging efficiency, and release reliability, establishing a more maintainable and extensible foundation for performance analysis within Perfetto.

Jul 1, 2025July 2025 — google/perfetto: Focused on CI reliability, symbolization enhancements, and ETM trace support. Delivered three features that improve testing workflow, profiling capabilities, and trace symbolization, while maintaining a lightweight surface area for future enhancements. Major bugs fixed: No discrete major bugs recorded for this month. Overall impact and accomplishments: Strengthened CI infrastructure to support llvm-dev-dependent tests, expanded symbolization options with a dedicated LLVM symbolizer, and added ETM-level metadata extraction to improve symbolization accuracy for ETM traces. These changes reduce debugging time, improve profiling fidelity, and accelerate engineers' ability to diagnose performance issues in complex workloads. Technologies/skills demonstrated: Docker/CI configuration (sandbox CI), LLVM tooling and dynamic linking, building a C API wrapper, build system changes, unit tests, and Perfetto SQL extension development.

Jun 1, 2025June 2025 performance summary focused on advancing memory analysis standardization within the Perfetto trace processor. Delivered a cohesive migration to the Perfetto SQL standard library for memory snapshot tables, including the creation of new views for intrinsic tables and corresponding updates to SQL view definitions and Python table configurations to align with the new standard library. This work establishes a standardized memory analysis workflow and reduces fragmentation across memory-related trace processing.
