A Practical Perfetto Introduction for AOSP and Linux Developers
Talkat Open Source Summit India 2026 · on Wednesday, 2026-06-17· at 16:25· Lotus Ballroom 2 (Level 3)·
summary
A hands‑on Perfetto primer that shows how to record traces on Android and embedded Linux using a Yocto tutorial, captures kernel ftrace events and custom Perfetto SDK or ATrace marks, and inspects a 15s Raspberry Pi trace where four I2C loops produce three visible custom slices and 215 µs read events. Demonstrates the trace viewer, built‑in statistics, frame timeline, binder flow counting (81 transactions in 58 ms), and programmatic analysis with the SQL trace processor and stack sampling flame graphs.
