5 | # RMK wants arm kernels compiled with frame pointers so hardwire this to y. | |
6 | # If you know what you are doing and are willing to live without stack | |
7 | # traces, you can get a slightly smaller kernel by setting this option to | |
8 | # n, but then RMK will have to kill you ;). | |

13 | If you say N here, the resulting kernel will be slightly smaller and | |
14 | faster. However, when a problem occurs with the kernel, the | |
15 | information that is reported is severely limited. Most people | |
16 | should say Y here. | |

18 | config DEBUG_USER | |
19 | bool "Verbose user fault messages" | |
20 | help | |
21 | When a user program crashes due to an exception, the kernel can | |
22 | print a brief message explaining what the problem was. This is | |
23 | sometimes helpful for debugging but serves no purpose on a | |
24 | production system. Most people should say N here. | |

31 | bool "Verbose kernel error messages" | |
32 | depends on DEBUG_KERNEL | |
33 | help | |
34 | This option controls verbose debugging information which can be | |
35 | printed when the kernel detects an internal error. This debugging | |
36 | information is useful to kernel hackers when tracking down problems, | |
37 | but mostly meaningless to other people. It's safe to say Y unless | |
38 | you are concerned with the code size or don't want to see these | |
39 | messages. | |

44 | depends on DEBUG_KERNEL | |
45 | help | |
46 | Say Y here to include definitions of printascii, printchar, printhex | |
47 | in the kernel. This is helpful if you are debugging code that | |
48 | executes before the console is initialized. | |
