| # Perfetto Protobuf definitions |
| |
| There are three groups of protos in the respective perfetto/X directories: |
| |
| `trace/`: This directory contains all protos that are output-ed by Perfetto |
| when capturing a trace. |
| |
| `config/`: This directory contains the configuration passed as input to |
| various parts of Perfetto, such as: |
| * (i) the whole trace config that the Consumer sends to the Perfetto trace |
| daemon. |
| * (ii) the per-data-source config that the trace daemon relays to each |
| Producer. |
| * (iii) the per-data-source descriptor that each Producer advertises to the |
| trace daemon when registering. |
| |
| `ipc/`: This directory contains the definition of the IPC surface between |
| the Perfetto components (Producer, trace daemon and Consumer(s)). This is |
| relevant only in some Perfetto build configuration (i.e. in Android but not |
| in Chrome). |
