This is fantastic, attempting to figure out what is happening at any point in time is quite hard, but showing that visually is so useful. I can't wait to use this. Troubleshooting stalls and other complaints, yay! Thank you Arjan!

Btw. While Ftrace is interesting, if you're trying to debug what happens
in the whole system, at the moment LTT and its visualizer are much more
useful: http://lttng.org/.

This short paper describes the differences between LTT and ftrace:

(Disclaimer: I'm a satisfied LTT user, and have used it before there even
was ftrace.)
