| 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. |

| 37 | Place segfaulting user mode processes on a wait queue instead of |
| 38 | delivering a terminating SIGSEGV to allow debugging with gdb. |
