The CRIS version of gdb can be used to remotely debug a running
|
|
Linux kernel via the serial debug port. Provided you have gdb-cris
|
|
installed, run gdb-cris vmlinux, then type
|
|
|
|
(gdb) set remotebaud 115200 <- kgdb uses 115200 as default
|
|
(gdb) target remote /dev/ttyS0 <- maybe you use another port
|
|
|
|
This should connect you to your booted kernel (or boot it now if you
|
|
didn't before). The kernel halts when it boots, waiting for gdb if
|
|
this option is turned on!

If you say Y here the resulting kernel image will include
|
|
debugging info resulting in a larger kernel image.
|
|
Say Y here only if you plan to use gdb to debug the kernel.
|
|
If you don't debug the kernel, you can say N.
|
|
|
|
config FRAME_POINTER
|
|
bool "Compile the kernel with frame pointers"
|
|
help
|
|
If you say Y here the resulting kernel image will be slightly larger
|
|
and slower, but it will give very useful debugging information.
|
|
If you don't debug the kernel, you can say N, but we may not be able
|
|
to solve problems without frame pointers.

config DEBUG_NMI_OOPS

bool "NMI causes oops printout"
|
|
help
|
|
If the system locks up without any debug information you can say Y
|
|
here to make it possible to dump an OOPS with an external NMI.
