| 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. |

| help |
| 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". |

| help |
| Place an empty function call at each marker site. Can be |
| dynamically changed for a probe function. |
