6 bool "KGDB: kernel debugger"
7 depends on HAVE_ARCH_KGDB
8 depends on DEBUG_KERNEL && EXPERIMENTAL
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
21 config KGDB_SERIAL_CONSOLE
22 tristate "KGDB: use kgdb over the serial console"
27 Share a serial console with kgdb. Sysrq-g must be used
28 to break in initially.
31 bool "KGDB: internal test suite"
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"
42 config KGDB_TESTS_ON_BOOT
43 bool "KGDB: Run tests on boot"
47 Run the kgdb tests on boot up automatically without the need
48 to pass in a kernel parameter
50 config KGDB_TESTS_BOOT_STRING
51 string "KGDB: which internal kgdb tests to run"
52 depends on KGDB_TESTS_ON_BOOT
55 This is the command string to send the kgdb test suite on
56 boot. See the drivers/misc/kgdbts.c for detailed
57 information about other strings you could use beyond the
60 config KGDB_LOW_LEVEL_TRAP
61 bool "KGDB: Allow debugging with traps in notifiers"
62 depends on X86 || MIPS
65 This will add an extra call back to kgdb for the breakpoint
66 exception handler on which will will allow kgdb to step
67 through a notify handler.
70 bool "KGDB_KDB: include kdb frontend for kgdb"
73 KDB frontend for kernel
76 bool "KGDB_KDB: keyboard as input device"
77 depends on VT && KGDB_KDB
80 KDB can use a PS/2 type keyboard for an input device
82 config KDB_CONTINUE_CATASTROPHIC
83 int "KDB: continue after catastrophic errors"
87 This integer controls the behaviour of kdb when the kernel gets a
88 catastrophic error, i.e. for a panic or oops.
89 When KDB is active and a catastrophic error occurs, nothing extra
90 will happen until you type 'go'.
91 CONFIG_KDB_CONTINUE_CATASTROPHIC == 0 (default). The first time
92 you type 'go', you will be warned by kdb. The secend time you type
93 'go', KDB tries to continue. No guarantees that the
94 kernel is still usable in this situation.
95 CONFIG_KDB_CONTINUE_CATASTROPHIC == 1. KDB tries to continue.
96 No guarantees that the kernel is still usable in this situation.
97 CONFIG_KDB_CONTINUE_CATASTROPHIC == 2. KDB forces a reboot.
98 If you are not sure, say 0.
