Renfeng developed a configurable GPU Render Stages Capture feature for the google/perfetto repository, enabling lightweight and flexible GPU tracing. By introducing the GpuRenderStagesConfig proto and integrating it into the build system using gn and protobuf, Renfeng provided granular control over which GPU metrics are traced, reducing overhead and improving performance analysis. The work included aligning with Qualcomm’s hardware optimizations by merging vendor-specific changes, which enhanced capture fidelity and stability. Renfeng also updated build and configuration documentation to support adoption and collaborated across teams to ensure smooth integration. This feature positions Perfetto for more efficient production GPU profiling workflows.
