(speaking for myself here) One of the cooler things about Google is getting just the slightest glimpse of the power of some of the tooling your wizard coworkers use.

https://perfetto.dev/ is one of those very cool tools. It's like kernel shark, but has really powerful SQL capabilities. It's well configured for use with Android and CrOS, but with classic Linux environments it can be a little daunting. So here are my notes on using it for upstream kernel development: https://gist.github.com/johnstultz-work/0ec4974e0929c4707bfd89c876ae4735

It's been really helpful to me recently in being able to demonstrate and root cause a number of problems with the upstream kernel.

I'm not savvy enough to be able to do all the SQL magic others know how to do, but even so I find it terribly useful. (And, again speaking personally) I really think it is an underutilized tool in the larger kernel community.

@jstultz I'll check all tracing tools and debuggers as they come by :-) QA is fun!
