This is actually an exact duplicate of this SO question which unfortunately does not have any answer. Is it possible to get a proper callgraph on ARM? I'm using oprofile 0.9.6 on an ARM926 which does not have performance counters so oprofile defaults to using the timer interrupt, I've set the --callgraph option and my app is compiled with the proper flags. I'm not trying to profile the kernel but I was wondering if I have to compile also the kernel with "framepointer" enabled in order to get a proper callgraph from my app.
Thanks
