   5           Say Y here to get to see options related to performance measurement,
   6           system-wide debugging, and testing. This option alone does not add any
   7           kernel code.

   9           If you say N, all options in this submenu will be skipped and
  10           disabled. If you're trying to debug the kernel itself, go see the
  11           Kernel Hacking menu.

  19           by profilers such as OProfile.

  26           OProfile is a profiling system capable of profiling the
  27           whole system, include the kernel, kernel modules, libraries,
  28           and applications.

  36         help
  37           Kprobes allows you to trap at almost any kernel address and
  38           execute a callback function.  register_kprobe() establishes
  39           a probepoint and specifies the callback.  Kprobes is useful
  40           for kernel debugging, non-intrusive instrumentation and testing.
  41           If in doubt, say "N".

  46           Place an empty function call at each marker site. Can be
