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

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".
