config HAVE_ARCH_KGDB bool menuconfig KGDB bool "KGDB: kernel debugger" depends on HAVE_ARCH_KGDB depends on DEBUG_KERNEL && EXPERIMENTAL help 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. if KGDB config KGDB_SERIAL_CONSOLE tristate "KGDB: use kgdb over the serial console" select CONSOLE_POLL select MAGIC_SYSRQ default y help Share a serial console with kgdb. Sysrq-g must be used to break in initially. config KGDB_TESTS bool "KGDB: internal test suite" default n help 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" config KGDB_TESTS_ON_BOOT bool "KGDB: Run tests on boot" depends on KGDB_TESTS default n help Run the kgdb tests on boot up automatically without the need to pass in a kernel parameter config KGDB_TESTS_BOOT_STRING string "KGDB: which internal kgdb tests to run" depends on KGDB_TESTS_ON_BOOT default "V1F100" help This is the command string to send the kgdb test suite on boot. See the drivers/misc/kgdbts.c for detailed information about other strings you could use beyond the default of V1F100. config KGDB_LOW_LEVEL_TRAP bool "KGDB: Allow debugging with traps in notifiers" depends on X86 || MIPS default n help This will add an extra call back to kgdb for the breakpoint exception handler on which will will allow kgdb to step through a notify handler. config KGDB_KDB bool "KGDB_KDB: include kdb frontend for kgdb" default n help KDB frontend for kernel config KDB_KEYBOARD bool "KGDB_KDB: keyboard as input device" depends on VT && KGDB_KDB default n help KDB can use a PS/2 type keyboard for an input device endif # KGDB
