| 4 | ---help--- | |
| 5 | Say Y here to get to see options related to performance measurement, | |
| 6 | system-wide debugging, and testing. This option alone does not add any | |
| 7 | kernel code. | |
| 8 | ||
| 9 | If you say N, all options in this submenu will be skipped and | |
| 10 | disabled. If you're trying to debug the kernel itself, go see the | |
| 11 | Kernel Hacking menu. | |

| 25 | OProfile is a profiling system capable of profiling the | |
| 26 | whole system, include the kernel, kernel modules, libraries, | |
| 27 | and applications. | |

| 29 | If unsure, say N. | |

| 49 | help | |
| 50 | Kprobes allows you to trap at almost any kernel address and | |
| 51 | execute a callback function. register_kprobe() establishes | |
| 52 | a probepoint and specifies the callback. Kprobes is useful | |
| 53 | for kernel debugging, non-intrusive instrumentation and testing. | |
| 54 | If in doubt, say "N". | |
