  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.

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

  30           If in doubt, say Y.

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

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

1168                   their output to the EmbeddedICE macrocell's DCC channel using
1169                   co-processor 14. This is known to work on the ARM9 style ICE
1170                   channel and on the XScale with the PEEDI.
1171
1172                   Note that the system will appear to hang during boot if there
1173                   is nothing connected to read from the DCC.

1178                   Semihosting enables code running on an ARM target to use
1179                   the I/O facilities on a host debugger/emulator through a
1180                   simple SVC call. The host debugger or emulator must have
1181                   semihosting enabled for the special svc call to be trapped
1182                   otherwise the kernel will crash.
1183
1184                   This is known to work with OpenOCD, as well as
1185                   ARM's Fast Models, or any other controlling environment
1186                   that implements semihosting.

1650           against certain classes of kernel exploits.
