Worked on the google/perfetto repository to deliver a configurable GPU Render Stages Capture feature, enabling lightweight and flexible GPU tracing. Developed the GpuRenderStagesConfig proto and integrated it into build systems and configuration files using gn and protobuf, allowing granular selection of GPU metrics to trace. This approach reduced tracing overhead and improved overall performance, aligning with hardware vendor optimizations by incorporating Qualcomm’s GPU renderstage changes. The work included updating documentation and collaborating across teams to ensure smooth adoption. Focused on build system configuration, GPU profiling, and performance analysis, the changes positioned Perfetto for more efficient production use and deployment.
