---help---
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!

depends on DEBUG_KERNEL
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.
config NO_SEGFAULT_TERMINATION
bool "Keep segfaulting processes"
help
Place segfaulting user mode processes on a wait queue instead of
delivering a terminating SIGSEGV to allow debugging with gdb.
