| This directory provides a stub implementation of perfetto. | |
| Perfetto backs libchrome tracing. Disabling tracing creates divergence between | |
| libchrome and Chromium. But we would prefer not to have tracing really enabled | |
| at this momenet. | |
| So we introduced a stub implementation of perfetto, so we can enable tracing on | |
| libchrome but it doesn't do anything underlying. |
