| 12 | ---help--- |
| 13 | The CRIS version of gdb can be used to remotely debug a running |
| 14 | Linux kernel via the serial debug port. Provided you have gdb-cris |
| 15 | installed, run gdb-cris vmlinux, then type |
| 16 | |
| 17 | (gdb) set remotebaud 115200 <- kgdb uses 115200 as default |
| 18 | (gdb) target remote /dev/ttyS0 <- maybe you use another port |
| 19 | |
| 20 | This should connect you to your booted kernel (or boot it now if you |
| 21 | didn't before). The kernel halts when it boots, waiting for gdb if |
| 22 | this option is turned on! |

| 27 | help |
| 28 | If you say Y here the resulting kernel image will include |
| 29 | debugging info resulting in a larger kernel image. |
| 30 | Say Y here only if you plan to use gdb to debug the kernel. |
| 31 | If you don't debug the kernel, you can say N. |

| 33 | config FRAME_POINTER |
| 34 | bool "Compile the kernel with frame pointers" |
| 35 | help |
| 36 | If you say Y here the resulting kernel image will be slightly larger |
| 37 | and slower, but it will give very useful debugging information. |
| 38 | If you don't debug the kernel, you can say N, but we may not be able |
| 39 | to solve problems without frame pointers. |

| 43 | help |
| 44 | If the system locks up without any debug information you can say Y |
| 45 | here to make it possible to dump an OOPS with an external NMI. |
