  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"
