IPC: introduce dont_reply flag to avoid useless empty replies This is to avoid wasteful wakeups (and CPU usage) for methods like NotifySharedMemoryUpdate(), where neither the client nor the host have anything meaningful to attach in reply. This allows to reduce our cpu usage, removing one IPC (hence a context switch) in the traced -> traced_probes direction. Change-Id: Id56e124bbad0870c4a29653289bf021cfdbf4c14
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.
