Instrumentation
        Support
       
       

Profiling
                support (EXPERIMENTAL) PROFILING
       
Say
Y here to enable the extended profiling support mechanisms used
by
profilers such as Oprofile.

OProfile
                        system profiling (EXPERIMENTAL) OPROFILE
               
OProfile
is a profiling system capable of profiling the
whole
system, include the kernel, kernel modules, libraries,
and
applications.
                If
unsure, say N.

Kprobes
                (EXPERIMENTAL) KPROBES
       
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".
