Debuggability and Tracing

One Line Summary

Chase that bug ...


2016 year can be easily called as a year of RDMA.

It has steady stream of new comers into the subsystem. Despite the fact that kernel provides a lot of built-in functionality for debugs and traces, most of such new drivers are not using them.

It is time to discuss:
1. Which services should IB core provide to decrease the current printks flood?
2. What can be commonized?
3. Do we want/need to extend kernel perf?
4. Which paths (hot/cold) do we want to instrument?
5. Do we want general error handling?
