ftrace_reader: Plumb metadata from CpuReader We want to neatly communicate some information (such as inode and pids) seen in the raw ftrace buffer to ProbesProducer where it can be used to gather aditional information on the inode/process. This CL plumbs an additional argument (FtraceMetadata) into the OnBundleComplete callback. FtraceMetadata is a container for 'out-of-band' information about the events in the bundle. For now this is just the number of overwritten events and the set of observed inodes. On the ProbesProducer side we wire this argument up to a log statement.

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