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.
if INSTRUMENTATION
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 OPROFILE_ARMV6

depends on OPROFILE && CPU_V6 && !SMP

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