Steve,

Was the kernel trace events infrastructure designed with that in mind? I.e. cross analysis? I must be missing something here, still ENOCOFFEE :-\

Yes, the libparsevents library was design for this from day one. That's why trace-cmd data file can be run on an ARM and read on x86, or PPC, or whatever. I did all my development testing against 32bit, 64bit and big and little endian. This was the case from the beginning.

When doing cross arch event analisys I tested:

    PERF_TYPE_HARDWARE                      = 0,
    PERF_TYPE_SOFTWARE                      = 1,
    PERF_TYPE_HW_CACHE                      = 3,

Not:

    PERF_TYPE_TRACEPOINT                    = 2,
    PERF_TYPE_RAW                           = 4,
    PERF_TYPE_BREAKPOINT                    = 5,
