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"
