+   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.

+   help
+     OProfile is a profiling system capable of profiling the
+     whole system, include the kernel, kernel modules, libraries,
+     and applications.
+
+     If unsure, say N.

+   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.
