   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 ;).
   9 config FRAME_POINTER
  10         bool
  11         default y
  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.

  26 config DEBUG_WAITQ
  27         bool "Wait queue debugging"
  28         depends on DEBUG_KERNEL

  30 config DEBUG_ERRORS
  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.
