| # Perfetto Binaries |
| |
| The source code for several perfetto binaries lives in the `external/perfetto` |
| project in the AOSP source tree. These binaries enable unbundled perfetto |
| tracing, and on-device trace processing. |
| |
| To set up the perfetto repository for the first time: |
| |
| ```bash |
| git clone https://android.googlesource.com/platform/external/perfetto/ perfetto_repo |
| perfetto_repo/tools/install-build-deps --android |
| ``` |
| |
| To build stripped binaries from the local repository: |
| |
| ```bash |
| ./generate_perfetto_binaries.py |
| ``` |
| |
| This script automates some of the build instructions documented |
| [here](https://perfetto.dev/docs/contributing/build-instructions). |
| |
| Some important things handled are: |
| - binary stripping (drastically reduces binary size) |
| - sets `monolithic_binaries = true` (important for unbundled usage) |
| - handles all architectures supported by macrobenchmark |
