| When a user program crashes due to an exception, the kernel can |
| print a brief message explaining what the problem was. This is |

| production system. Most people should say N here. |
| |
| In addition, you need to pass user_debug=N on the kernel command |
| line to enable this feature. N consists of the sum of: |
| |
| 1 - undefined instruction events |

| help |
| Say Y here if you want the debug print routines to direct |

| co-processor 14. This is known to work on the ARM9 style ICE |
| channel and on the XScale with the PEEDI. |

| config DEBUG_SEMIHOSTING |
| bool "Kernel low-level debug output via semihosting I/O" |
| help |
| Semihosting enables code running on an ARM target to use |
| the I/O facilities on a host debugger/emulator through a |
| simple SVC call. The host debugger or emulator must have |
| semihosting enabled for the special svc call to be trapped |
| otherwise the kernel will crash. |
| |
| This is known to work with OpenOCD, as well as |
| ARM's Fast Models, or any other controlling environment |
| that implements semihosting. |
| |
| For more details about semihosting, please see |

| This option influences the normal decompressor output for |

| decompressor output because it is not possible to know where to |
