14 ---help---
15 The CRIS version of gdb can be used to remotely debug a running
16 Linux kernel via the serial debug port. Provided you have gdb-cris
17 installed, run gdb-cris vmlinux, then type
18
19 (gdb) set remotebaud 115200 <- kgdb uses 115200 as default
20 (gdb) target remote /dev/ttyS0 <- maybe you use another port
21
22 This should connect you to your booted kernel (or boot it now if you
23 didn't before). The kernel halts when it boots, waiting for gdb if
24 this option is turned on!

31 If the system locks up without any debug information you can say Y
32 here to make it possible to dump an OOPS with an external NMI.

34 config NO_SEGFAULT_TERMINATION
35 bool "Keep segfaulting processes"
36 help
37 Place segfaulting user mode processes on a wait queue instead of
38 delivering a terminating SIGSEGV to allow debugging with gdb.
