But I looked at Systemtap before, and as I remember, it is very flexible, but it only traces function calls. (or am I missing something?) I also need this scheduler-tracer, besides for fully fledged X86 systems, also for ARM based boards also with a very minimal userland, and limited flash. So, it has to be lightweight also. I can only use cross-compilers to build the tools... (something Systemtap is not good at as I remember...) So, I am missing something here, or it is unfortunately not what I am looking for...
