I've got a following error during a simple test:

  $ ./perf record -- sleep 1

    Error: sys_perf_event_open() syscall returned with 22 (Invalid argument).
           /bin/dmesg may provide additional information.

    Fatal: No CONFIG_PERF_EVENTS=y kernel support configured?

  sleep: Terminated


Any thoughts?

Thanks,
Namhyung
