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. | |

35 | This is a kgdb I/O module specifically designed to test | |
36 | kgdb's internal functions. This kgdb I/O module is | |
37 | intended to for the development of new kgdb stubs | |
38 | as well as regression testing the kgdb internals. | |
39 | See the drivers/misc/kgdbts.c for the details about | |
40 | the tests. The most basic of this I/O module is to boot | |
41 | a kernel boot arguments "kgdbwait kgdbts=V1F100" | |

88 | This integer controls the behaviour of kdb when the kernel gets a | |

91 | will happen until you type 'go'. | |
92 | CONFIG_KDB_CONTINUE_CATASTROPHIC == 0 (default). The first time | |
93 | you type 'go', you will be warned by kdb. The secend time you type | |
94 | 'go', KDB tries to continue. No guarantees that the | |
95 | kernel is still usable in this situation. | |

97 | No guarantees that the kernel is still usable in this situation. | |
