Perfetto (https://perfetto.dev/) is a system profiling, app tracing and trace analysis framework. We started using Perfetto for studying a few performance-related problems for OpenBMC-based systems (both the BMC and the host) and we feel it would be good if Perfetto is included into OpenEmbedded, since embedded systems are usually expected to have predictable performance characteristics, and having a good set of performance analysis tools would make this work easier.
