    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.
    8 
    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.

   18           Say Y here to enable the extended profiling support mechanisms used
   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.
   29 
   30           If unsure, say N.

   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".

   43 config MARKERS
   44         bool "Activate markers"

   46           Place an empty function call at each marker site. Can be
   47           dynamically changed for a probe function.
