"Kernel debugging" select "KGDB: kernel debugging with remote gdb".
+ It is advised, but not required that you turn on the
+ CONFIG_FRAME_POINTER kernel option. This option inserts code to
+ into the compiled executable which saves the frame information in
+ registers or on the stack at different points which will allow a
+ debugger such as gdb to more accurately construct stack back traces
+ while debugging the kernel.

+
+ If the architecture that you are using supports the kernel option
+ CONFIG_DEBUG_RODATA, you should consider turning it off. This
+ option will prevent the use of software breakpoints because it
+ marks certain regions of the kernel's memory space as read-only.
+ If kgdb supports it for the architecture you are using, you can
+ use hardware breakpoints if you desire to run with the
+ CONFIG_DEBUG_RODATA option turned on, else you need to turn off
+ this option.

Next you should choose one of more I/O drivers to interconnect debugging
host and debugged target. Early boot debugging requires a KGDB
I/O driver that supports early debugging and the driver must be
