  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.

  21         help
  22           Kprobes allows you to trap at almost any kernel address and
  23           execute a callback function.  register_kprobe() establishes
  24           a probepoint and specifies the callback.  Kprobes is useful
  25           for kernel debugging, non-intrusive instrumentation and testing.
  26           If in doubt, say "N".

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

  44           If you say Y here, GDB stub will break into the program as soon as
  45           possible, leaving the program counter at the beginning of

  53           would like kernel messages to be formatted into GDB $O packets so
  54           that GDB prints them as program output, say 'Y'.
