Perfetto replaces systrace and runs on Android and Linux; Android devices (Android 9/10+) have Perfetto and Tracebox installed so tracing works out of the box, while Yocto provides a recipe that lags mainline and contains a simple typo bug you must patch. Recording uses tracebox auto-start or the record_android_trace helper and stores raw traces on the device then pulls them to host. Analysis uses trace_processor SQL, the web UI with pin tracks and visual binder flow linking to correlate IPC and CPU scheduling.
