  13        help
  14          If you say Y here you will confirm the start and the end of
  15          decompressing Linux seeing "Uncompressing Linux... " and
  16          "Ok, booting the kernel.\n" on console.

  20        depends on DEBUG_KERNEL
  21        default n
  22        help
  23          If you say Y here the kernel will execute a list of misaligned memory
  24          accesses to make sure the misalignment handler deals them with
  25          correctly.  If it does not, the kernel will throw a BUG.

  27config KPROBES
  28        bool "Kprobes"
  29        depends on DEBUG_KERNEL
  30        help
  31          Kprobes allows you to trap at almost any kernel address and
  32          execute a callback function.  register_kprobe() establishes
  33          a probepoint and specifies the callback.  Kprobes is useful
  34          for kernel debugging, non-intrusive instrumentation and testing.
  35          If in doubt, say "N".

  42        help
  43          If you say Y here, it will be possible to remotely debug the kernel
  44          using gdb. This enlarges your kernel ELF image disk size by several
  45          megabytes and requires a machine with more than 16 MB, better 32 MB
  46          RAM to avoid excessive linking time. This is only useful for kernel
  47          hackers. If unsure, say N.

  53          If you say Y here, GDB stub will break into the program as soon as
  54          possible, leaving the program counter at the beginning of
  55          start_kernel() in init/main.c.

  61          If you are using GDB for remote debugging over a serial port and
  62          would like kernel messages to be formatted into GDB $O packets so
  63          that GDB prints them as program output, say 'Y'.

  69          This causes debugging messages to be displayed at various points
  70          during execution of the GDB stub routines. Such messages will be
  71          displayed on ttyS0 if that isn't the GDB stub's port, or ttySM0
  72          otherwise.
