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"

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

57 information about other strings you could use beyond the
58 default of V1F100.
