ftrace_reader: Plumb block_device_ids via metadata

Add the block device id with each inode number to metadata.
Use the stored device id in probes_producer to ensure duplicate
inode numbers are matched correctly.
All our current format files have had dev id and then inode immediately after.
When an inode number is seen, get the most recent dev id and add the pair
to metadata.

Perfetto - Performance instrumentation and logging for POSIX platforms

This project is meant to be built both as part of the Android tree and from a standalone checkout

For internal docs see this page

Supported platforms

Android is the platform targeted in the first milestones. Right now Linux desktop and OSX are maintained best-effort.

Contributing

This project uses Android AOSP Gerrit for code reviews and uses the Google C++ style. Currently targets -std=c++11.

You can use both git cl upload from Chromium depot tools or Android repo to upload patches.

git cl is quite convenient as it supports code auto-formatting via git cl format.

See https://source.android.com/source/contributing for more details about external contributions and CLA signing.

Build instructions

See docs/build_instructions.md

Running Perfetto

See docs/running_perfetto.md

Continuous integration

Continuous build and test coverage is available at perfetto-ci.appspot.com. Trybots: CLs uploaded to gerrit are automatically submitted to TravisCI within one minute and made available on the CI page above. The relevant code lives in the infra/ directory.

Run tests

On the host (Linux / OSX)

$ tools/ninja -C out/default (tracing_unittests | tracing_benchmarks)
$ out/default/tracing_unittests --gtest_help

On Android

Either connect a device in ADB mode or use the bundled emulator.

To start the emulator:
$ tools/run_android_emulator (arm | arm64) &

To run the tests (either on the emulator or physical device):
$ tools/run_android_test out/default tracing_unittests
