9 | If this option is disabled, you allow userspace (root) access to all | |
10 | of memory, including kernel and userspace memory. Accidental | |
11 | access to this is obviously disastrous, but specific access can | |
12 | be used by people debugging the kernel. | |
13 | ||
14 | If this option is switched on, the /dev/mem file only allows | |
15 | userspace access to memory mapped peripherals. | |
16 | ||
17 | If in doubt, say Y. | |

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

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

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

75 | Note that selecting this option will limit the kernel to a single |
76 | UART definition, as specified below. Attempting to boot the kernel | |
77 | image on a different platform *will not work*, so this option should | |
78 | not be enabled for kernels that are intended to be portable. | |

832 | Semihosting enables code running on an ARM target to use |
833 | the I/O facilities on a host debugger/emulator through a | |
62194bda | 834 | simple SVC call. The host debugger or emulator must have |
b0df8986 RK |
835 | semihosting enabled for the special svc call to be trapped |
836 | otherwise the kernel will crash. | |
650e3f0d | 837 | |
62194bda | 838 | This is known to work with OpenOCD, as well as |
b0df8986 RK |
839 | ARM's Fast Models, or any other controlling environment |
840 | that implements semihosting. | |

1144 | config PID_IN_CONTEXTIDR |
1145 | bool "Write the current PID to the CONTEXTIDR register" | |
1146 | depends on CPU_COPY_V6 | |
1147 | help | |
1148 | Enabling this option causes the kernel to write the current PID to | |
1149 | the PROCID field of the CONTEXTIDR register, at the expense of some | |
1150 | additional instructions during context switch. Say Y here only if you | |
1151 | are planning to use hardware trace tools with this kernel. | |
