  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
  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"

  55          This is the command string to send the kgdb test suite on
  56          boot.  See the drivers/misc/kgdbts.c for detailed
  57          information about other strings you could use beyond the
  58          default of V1F100.
