  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"

  58           default of V1F100.
