|

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.

OProfile is a profiling system capable of profiling the
|

whole system, include the kernel, kernel modules, libraries,
|
|
and applications.

If unsure, say N.

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".

Place an empty function call at each marker site. Can be
