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:

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:

./generate_perfetto_binaries.py

This script automates some of the build instructions documented here.

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
