| 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 ;). |

| 12 | help |
| 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. |

| 41 | # These options are only for real kernel hackers who want to get their hands dirty. |
| 42 | config DEBUG_LL |
| 43 | bool "Kernel low-level debugging functions" |
| 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. |
