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

  52           This is the command string to send the kgdb test suite on

  54           information about other strings you could use beyond the
  55           default of V1F100.
