PROFILE
Martin Liu
Over a two-month period, contributed to the google/perfetto repository by developing and enhancing memory tracing and profiling features for Android systems. Focused on improving memory observability, the work included refining gralloc memory attribution for more accurate process tracking and extending CMA/KMEM tracing across kernel versions using C++ and Protocol Buffers. Enhanced the Perfetto UI and PixelMemory plugin with unified memory usage analysis, enabling multi-process monitoring and aggregated views. Refactored memory tracking logic for maintainability and ensured stable, idempotent table initialization. Leveraged TypeScript and SQL to deliver robust frontend and backend improvements, supporting faster debugging and comprehensive performance analysis workflows.

Jul 1, 2025July 2025 (google/perfetto): Delivered two memory-tracing enhancements to boost Android memory observability and debugging efficiency. Gralloc memory attribution improvements tighten allocator process-name matching to improve memory tracking accuracy for Android allocations. Enhanced CMA/KMEM memory tracing and parser support adds new ftrace events for CMA and KMEM and updates the parser to support CMA allocation events across kernel versions (v6.1+), enabling detailed memory management tracing. UI enhancements surface CMA allocation/finish information to streamline debugging and visibility into allocation lifecycles.
