are there any thoughts on how much of the perf.data is portable and how much it should be? 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?
Endianness issues? ARM EB? There are some patches by Jiri Olsa that may help you if that is the case.
latest version sent today, there's description of tests I did: http://marc.info/?l=linux-kernel&m=133715172512742&w=2
Each time I run new sort of test, another endianity issue is hit. so, tracepoints.. I'll check ;)
