menuconfig INSTRUMENTATION

        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.

config PROFILING

        bool "Profiling support (EXPERIMENTAL)"

        help

          Say Y here to enable the extended profiling support mechanisms used

          by profilers such as OProfile.

config OPROFILE

        tristate "OProfile system profiling (EXPERIMENTAL)"

        depends on PROFILING && !UML

        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 KALLSYMS && MODULES && !UML

        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.
