-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
- depends on HAVE_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.

-config KPROBES
- bool "Kprobes"
- depends on KALLSYMS && MODULES && !UML
- depends on HAVE_KPROBES
- 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.
