        bool "Instrumentation Support"
        default y
        ---help---
          Say Y here to get to see options related to performance measurement,
          system-wide debugging, and testing. This option alone does not add any
          kernel code.

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

        help
          Say Y here to enable the extended profiling support mechanisms used
          by profilers such as OProfile.

        tristate "OProfile system profiling (EXPERIMENTAL)"

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

          If unsure, say N.

config KPROBES
        bool "Kprobes"

        depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32
        help
          Kprobes allows you to trap at almost any kernel address and
          execute a callback function.  register_kprobe() establishes
          a probepoint and specifies the callback.  Kprobes is useful
          for kernel debugging, non-intrusive instrumentation and testing.
          If in doubt, say "N".

config MARKERS
        bool "Activate markers"
        help
          Place an empty function call at each marker site. Can be
          dynamically changed for a probe function.
