No decision yet. I'm still waiting for an answer on
https://lore.kernel.org/linux-trace-devel/9ac9a1af-6829-425a-7943-755decf7c273@xxxxxxxxx/
regarding maintenance of different tracepoint revisions. That would be
implicit when keeping the plugin in lock-step with the tracepoints in
the same repo.

But then the question would be how mature the interface lifecycle
management of kernelshark and libs is /wrt external plugins. Those may
need to account for potential changes in those APIs over the time, right?

We will likely pick the path that is least inconvenient.

Makes sense ;)

Seriously: Is there some caption somewhere that explains the meaning of
colors? If so, how to hook into that?

Thanks,
