bool "System profiling support"
config ETRAX_KGDB
bool "Use kernel GDB debugger"
---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!
config DEBUG_INFO
bool "Compile the kernel with debug info"
help
If you say Y here the resulting kernel image will include
debugging info resulting in a larger kernel image.
Say Y here only if you plan to use gdb to debug the kernel.
If you don't debug the kernel, you can say N.
config FRAME_POINTER
bool "Compile the kernel with frame pointers"
help
If you say Y here the resulting kernel image will be slightly larger
and slower, but it will give very useful debugging information.
If you don't debug the kernel, you can say N, but we may not be able
to solve problems without frame pointers.
config DEBUG_NMI_OOPS
bool "NMI causes oops printout"
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.
