  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.

  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
  41           faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled,
  42           when a problem occurs with the kernel, the information that is

  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

1171                   Semihosting enables code running on an ARM target to use
1172                   the I/O facilities on a host debugger/emulator through a
1173                   simple SVC call. The host debugger or emulator must have
1174                   semihosting enabled for the special svc call to be trapped
1175                   otherwise the kernel will crash.
1176
1177                   This is known to work with OpenOCD, as well as
1178                   ARM's Fast Models, or any other controlling environment
1179                   that implements semihosting.

1181                   For more details about semihosting, please see

1642           patching and dynamic kernel tracing - and they might also protect
1643           against certain classes of kernel exploits.
