11 | Say Y here if you want to show the kernel pagetable layout in a | |
12 | debugfs file. This information is only useful for kernel developers | |
13 | who are working in architecture specific areas of the kernel. | |
14 | It is probably not a good idea to enable this feature in a production | |
15 | kernel. | |
16 | If in doubt, say "N" | |

26 | help |
27 | If you say N here, the resulting kernel will be slightly smaller and | |
adf8b37b CM |
28 | faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled, |
29 | when a problem occurs with the kernel, the information that is | |
30 | reported is severely limited. | |

36 | help | |
37 | This option enables stack unwinding support in the kernel | |
38 | using the information automatically generated by the | |
39 | compiler. The resulting kernel image is slightly bigger but | |
40 | the performance is not affected. Currently, this feature | |
41 | only works with EABI compilers. If unsure say Y. | |

49 | bool "Verbose user fault messages" | |
50 | help | |
51 | When a user program crashes due to an exception, the kernel can | |
52 | print a brief message explaining what the problem was. This is | |
53 | sometimes helpful for debugging but serves no purpose on a | |
54 | production system. Most people should say N here. | |
55 | ||
56 | In addition, you need to pass user_debug=N on the kernel command | |
57 | line to enable this feature. N consists of the sum of: | |
58 | ||
59 | 1 - undefined instruction events | |
60 | 2 - system calls | |
61 | 4 - invalid data aborts | |
62 | 8 - SIGSEGV faults | |
63 | 16 - SIGBUS faults | |

1218 | bool "Kernel low-level debugging via ARM Ltd PL01x Primecell UART" | |
1219 | help | |
1220 | Say Y here if you wish the debug print routes to direct | |
1221 | their output to a PL01x Primecell UART. You can use | |
1222 | this option to provide the parameters for the UART | |
1223 | rather than selecting one of the platform specific | |
1224 | options above if you know the parameters for the port. | |
1225 | ||
1226 | This option is preferred over the platform specific | |
1227 | options; the platform specific options are deprecated | |
1228 | and will be soon removed. | |

1588 | This option influences the normal decompressor output for | |

1631 | This option helps catch unintended modifications to loadable | |

1635 | against certain classes of kernel exploits. | |
