15 | ---help--- |
| 16 | The CRIS version of gdb can be used to remotely debug a running | |
| 17 | Linux kernel via the serial debug port. Provided you have gdb-cris | |
| 18 | installed, run gdb-cris vmlinux, then type | |
| 19 | ||
| 20 | (gdb) set remotebaud 115200 <- kgdb uses 115200 as default | |
| 21 | (gdb) target remote /dev/ttyS0 <- maybe you use another port | |
| 22 | ||
| 23 | This should connect you to your booted kernel (or boot it now if you | |
| 24 | didn't before). The kernel halts when it boots, waiting for gdb if | |
| 25 | this option is turned on! | |

| 31 | help | |
| 32 | If the system locks up without any debug information you can say Y | |
| 33 | here to make it possible to dump an OOPS with an external NMI. | |

| 38 | Place segfaulting user mode processes on a wait queue instead of | |
| 39 | delivering a terminating SIGSEGV to allow debugging with gdb. | |
