| 14 | If you say Y here you will confirm the start and the end of | |
| 15 | decompressing Linux seeing "Uncompressing Linux... " and | |
| 16 | "Ok, booting the kernel.\n" on console. | |

| 22 | help | |
| 23 | If you say Y here the kernel will execute a list of misaligned memory | |
| 24 | accesses to make sure the misalignment handler deals them with | |
| 25 | correctly. If it does not, the kernel will throw a BUG. | |

27 | config KPROBES |
| 28 | bool "Kprobes" | |
| 29 | depends on DEBUG_KERNEL | |
| 30 | help | |
| 31 | Kprobes allows you to trap at almost any kernel address and | |
| 32 | execute a callback function. register_kprobe() establishes | |
| 33 | a probepoint and specifies the callback. Kprobes is useful | |
| 34 | for kernel debugging, non-intrusive instrumentation and testing. | |
| 35 | If in doubt, say "N". | |

| 42 | help | |
| 43 | If you say Y here, it will be possible to remotely debug the kernel | |
| 44 | using gdb. This enlarges your kernel ELF image disk size by several | |
| 45 | megabytes and requires a machine with more than 16 MB, better 32 MB | |
| 46 | RAM to avoid excessive linking time. This is only useful for kernel | |
| 47 | hackers. If unsure, say N. | |

| 52 | help | |
| 53 | If you say Y here, GDB stub will break into the program as soon as | |
| 54 | possible, leaving the program counter at the beginning of | |
| 55 | start_kernel() in init/main.c. | |

| 60 | help | |
| 61 | If you are using GDB for remote debugging over a serial port and | |
| 62 | would like kernel messages to be formatted into GDB $O packets so | |
| 63 | that GDB prints them as program output, say 'Y'. | |

| 69 | This causes debugging messages to be displayed at various points | |
| 70 | during execution of the GDB stub routines. Such messages will be | |
| 71 | displayed on ttyS0 if that isn't the GDB stub's port, or ttySM0 | |
