If you say Y here, it will be possible to remotely debug the
|
|
kernel using gdb. It is recommended but not required, that
|
|
you also turn on the kernel config option
|
|
CONFIG_FRAME_POINTER to aid in producing more reliable stack
|
|
backtraces in the external debugger. Documentation of
|
|
kernel debugger is available at http://kgdb.sourceforge.net

|
as well as in DocBook form in Documentation/DocBook/. If
|
|
unsure, say N.

This is a kgdb I/O module specifically designed to test
|
|
kgdb's internal functions. This kgdb I/O module is
|
|
intended to for the development of new kgdb stubs
|
|
as well as regression testing the kgdb internals.
|
|
See the drivers/misc/kgdbts.c for the details about
|
|
the tests. The most basic of this I/O module is to boot
|

a kernel boot arguments "kgdbwait kgdbts=V1F100"
