| # Perfetto <-> Ftrace interoperability |
| |
| *** note |
| **This doc is WIP**, stay tuned. |
| <!-- TODO(primiano): write ftrace doc. --> |
| *** |
| |
| This doc should: |
| - Describe the ftrace trace_pipe_raw -> protobuf translation. |
| - Describe how we deal with kernel ABI (in)stability and ftrace fields changing |
| over kernel versions (we process `event/**/format files on-device`). |
| - Describe how to generate ftrace protos (`tools/pull_ftrace_format_files.py`, |
| `tools/udate_protos.py`) |
| - Describe how session multiplexing works. |
| |
| Code lives in [/src/traced/probes/ftrace](/src/traced/probes/ftrace/). |
