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

20 | ---help--- | |
21 | If this option is disabled, you allow userspace (root) access to all | |
22 | of memory, including kernel and userspace memory. Accidental | |
23 | access to this is obviously disastrous, but specific access can | |
24 | be used by people debugging the kernel. | |
25 | ||
26 | If this option is switched on, the /dev/mem file only allows | |
27 | userspace access to memory mapped peripherals. | |
28 | ||
29 | If in doubt, say Y. | |

40 | If you say N here, the resulting kernel will be slightly smaller and | |
adf8b37b CM |
41 | faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled, |
42 | when a problem occurs with the kernel, the information that is | |

49 | help | |
50 | This option enables stack unwinding support in the kernel | |
51 | using the information automatically generated by the | |
52 | compiler. The resulting kernel image is slightly bigger but | |
53 | the performance is not affected. Currently, this feature | |
54 | only works with EABI compilers. If unsure say Y. | |

63 | help | |
64 | When a user program crashes due to an exception, the kernel can | |
65 | print a brief message explaining what the problem was. This is | |
66 | sometimes helpful for debugging but serves no purpose on a | |
67 | production system. Most people should say N here. | |
68 | ||
69 | In addition, you need to pass user_debug=N on the kernel command | |
70 | line to enable this feature. N consists of the sum of: | |
71 | ||
72 | 1 - undefined instruction events | |
73 | 2 - system calls | |
74 | 4 - invalid data aborts | |
75 | 8 - SIGSEGV faults | |

1152 | This option influences the normal decompressor output for | |
1153 | multiplatform kernels. Normally, multiplatform kernels disable | |
1154 | decompressor output because it is not possible to know where to | |
1155 | send the decompressor output. | |
1156 | ||
1157 | When this option is set, the selected DEBUG_LL output method | |
1158 | will be re-used for normal decompressor output on multiplatform | |
1159 | kernels. | |

1202 | This option helps catch unintended modifications to loadable | |
1203 | kernel module's text and read-only data. It also prevents execution | |
1204 | of module data. Such protection may interfere with run-time code | |
1205 | patching and dynamic kernel tracing - and they might also protect | |
1206 | against certain classes of kernel exploits. | |
1207 | If in doubt, say "N". | |
