1# Perfetto Protobuf definitions 2 3There are three groups of protos in the respective perfetto/X directories: 4 5`trace/`: This directory contains all protos that are output-ed by Perfetto 6when capturing a trace. 7 8`config/`: This directory contains the configuration passed as input to 9various parts of Perfetto, such as: 10 * (i) the whole trace config that the Consumer sends to the Perfetto trace 11 daemon. 12 * (ii) the per-data-source config that the trace daemon relays to each 13 Producer. 14 * (iii) the per-data-source descriptor that each Producer advertises to the 15 trace daemon when registering. 16 17`ipc/`: This directory contains the definition of the IPC surface between 18the Perfetto components (Producer, trace daemon and Consumer(s)). This is 19relevant only in some Perfetto build configuration (i.e. in Android but not 20in Chrome). 21
