| 2 | |
| 3 | There 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 |
| 6 | when capturing a trace. |
| 7 | |
| 8 | `config/`: This directory contains the configuration passed as input to |
| 9 | various 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 |
| 18 | the Perfetto components (Producer, trace daemon and Consumer(s)). This is |
| 19 | relevant only in some Perfetto build configuration (i.e. in Android but not |
| 20 | in Chrome). |
