If you say Y here, it will be possible to remotely debug the kernel
|
|
using gdb. This enlarges your kernel ELF image disk size by several
|
|
megabytes and requires a machine with more than 16 MB, better 32 MB
|
|
RAM to avoid excessive linking time. This is only useful for kernel
|
|
hackers. If unsure, say N.

If you say Y here, GDB stub will break into the program as soon as
|

possible, leaving the program counter at the beginning of

start_kernel() in init/main.c.

If you are using GDB for remote debugging over a serial port and
|
|
would like kernel messages to be formatted into GDB $O packets so
|
|
that GDB prints them as program output, say 'Y'.
