In general you want to have two categories: - A debug run with lots of debug switches enabled like lockdep, debug-objects and what not. - A "production" run where all of those expensive debug swiches are off. That "sleeping while atomic" is cheap and could remain enabled. In these two types of config you want to run tests. As mentioned here hackbench, stress-ng, … is a good start. You want also make sure that you "use" all of your hardware that could be used in "production" including disk, i2c, gpio, … and what else might be there. While doing this, you don't want see any warnings in your debug config. In your production config you want also to measure the responsibility/ latency of the system. cyclictest is good and simple but depending on your usecase it might also include the latency of IPC communication, ping-ping of network communication, etc. Sebastian
