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.
Share a serial console with kgdb. Sysrq-g must be used to break in initially.
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"
Run the kgdb tests on boot up automatically without the need to pass in a kernel parameter
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.
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.
