This option enables special console drivers which allow the kernel
|
|
to print messages very early in the bootup process.
|
|
|
|
This is useful for kernel debugging when your machine crashes very
|
|
early before the console code is initialized. For normal operation,
|
|
it is not recommended because it looks ugly on some machines and
|
|
doesn't cooperate with an X server. You should normally say N here,
|
|
unless you want to debug such a crash.

On some platforms, there is currently no way for the boot loader to
|
|
pass arguments to the kernel. For these platforms, you can supply
|
|
some command-line options at build time by entering them here. In
|
|
other cases you can specify kernel args so that you don't have
|
|
to set them up in board prom initialization routines.

This option enables Enable additional debug checks before going into
|
|
CPU idle loop. For details on these checks, see
|
|
arch/mips/kernel/smtc.c. This debugging option result in significant
|
|
overhead so should be disabled in production kernels.

If you say Y here, some debugging macros will do run-time checking.
|
|
If you say N here, those macros will mostly turn to no-ops. See
|
|
arch/mips/include/asm/debug.h for debugging macros.
|
|
If unsure, say N.
