If you say N here, the resulting kernel will be slightly smaller and
|
||
|
|
faster. However, when a problem occurs with the kernel, the
|
||
|
|
information that is reported is severely limited. Most people
|
||
|
|
should say Y here.

|

|
|
When a user program crashes due to an exception, the kernel can
|
||
|
|
print a brief message explaining what the problem was. This is
|
||
|
|
sometimes helpful for debugging but serves no purpose on a
|
||
|
|
production system. Most people should say N here.

This option controls verbose debugging information which can be
|
||
|
|
printed when the kernel detects an internal error. This debugging
|
||
|
|
information is useful to kernel hackers when tracking down problems,
|
||
|
|
but mostly meaningless to other people. It's safe to say Y unless
|
||
|
|
you are concerned with the code size or don't want to see these
|
||
|
|
messages.

Say Y here to include definitions of printascii, printchar, printhex
|
||
|
|
in the kernel. This is helpful if you are debugging code that
|
||
|
|
executes before the console is initialized.
