Yes, xcall is an event powertop should report, currently xcall dtrace probe doesn't take the function as an argument, that prevents us getting the caller easily. Is it possible to change the current probe? execname may be acceptable, but we should exclude execname=powertop, what do you think? Thanks, -Aubrey
