9 | If you say N, all options in this submenu will be skipped and | ||

26 | OProfile is a profiling system capable of profiling the | ||
27 | whole system, include the kernel, kernel modules, libraries, | ||
28 | and applications. | ||

36 | help | ||
37 | Kprobes allows you to trap at almost any kernel address and | ||
38 | execute a callback function. register_kprobe() establishes | ||
39 | a probepoint and specifies the callback. Kprobes is useful | ||
40 | for kernel debugging, non-intrusive instrumentation and testing. | ||
41 | If in doubt, say "N". | ||
