Say Y here if your target has the gdb-sh-stub
|
||
|
|
package from www.m17n.org (or any conforming standard LinuxSH BIOS)
|
||
|
|
in FLASH or EPROM. The kernel will use standard BIOS calls during
|
||
|
|
boot for various housekeeping tasks (including calls to read and
|
||
|
|
write characters to a system console, get a MAC address from an
|
||
|
|
on-board Ethernet interface, and shut down the hardware). Note this
|
||
|
|
does not work with machines with an existing operating system in
|
||
|
|
mask ROM and no flash (WindowsCE machines fall in this category).

If unsure, say N.

Say Y here to redirect kernel printk messages to the serial port
|
||
|
|
used by the SH-IPL bootloader, starting very early in the boot
|
||
|
|
process and ending when the kernel's serial console is initialised.
|
||
|
|
This option is only useful porting the kernel to a new machine,
|
||
|
|
when the kernel may crash or hang before the serial console is
|
||
|
|
initialised. If unsure, say N.

Include in-kernel hooks for kgdb, the Linux kernel source level

debugger. See <http://kgdb.sourceforge.net/> for more information.

Unless you are intending to debug the kernel, say N here.

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.
