  10          If you say Y here, it will be possible to remotely debug the
  11          kernel using gdb.  It is recommended but not required, that
  12          you also turn on the kernel config option
  13          CONFIG_FRAME_POINTER to aid in producing more reliable stack
  14          backtraces in the external debugger.  Documentation of
  15          kernel debugger is available at http://kgdb.sourceforge.net
  16          as well as in DocBook form in Documentation/DocBook/.  If
  17          unsure, say N.

  34          This is a kgdb I/O module specifically designed to test
  35          kgdb's internal functions.  This kgdb I/O module is
  36          intended to for the development of new kgdb stubs
  37          as well as regression testing the kgdb internals.
  38          See the drivers/misc/kgdbts.c for the details about
  39          the tests.  The most basic of this I/O module is to boot
  40          a kernel boot arguments "kgdbwait kgdbts=V1F100"
