I thought perf can also exploit Intel processor trace?


It can! You can read more about how to do that yourself here: https://perf.wiki.kernel.org/index.php/Perf_tools_support_fo....

magic-trace uses perf. If you want, you can think of it as a mere "alternative frontend" for the Intel PT decoding offered by perf.


Ah okay, I misunderstood magic-trace to be an alternative to perf.
