Perfetto

An RBLN trace in Perfetto: four ATOM devices, each with its six command tracks busy.

Perfetto is a web-based visualization tool for performance tracing and analysis. It is designed to visualize and debug system performance, and offers a user-friendly interface for analyzing time-based events. Visit the official Perfetto documentation to get detailed information.

You can easily visualize a profiling result by dragging and dropping an output *.pb file generated by the RBLN Profiler onto the Perfetto online trace viewer.
