I'm interesting in recording scheduler activity on one machine and then replaying on another. As I can see, replaying x86 perf.data on ARM doesn't work. At least, should it work with a small subset of recorded events (for example, sched:sched_switch, sched:sched_process_exit, sched:sched_process_fork, sched:sched_wakeup and sched:sched_migrate_task) on the same architecture?
