| 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" | |
