source "lib/Kconfig.debug"
# RMK wants arm kernels compiled with frame pointers so hardwire this to y.
# If you know what you are doing and are willing to live without stack
# traces, you can get a slightly smaller kernel by setting this option to
# n, but then RMK will have to kill you ;).
config FRAME_POINTER
bool
default y
help
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.
config DEBUG_USER
bool "Verbose user fault messages"
help
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.
config DEBUG_WAITQ
bool "Wait queue debugging"
depends on DEBUG_KERNEL
config DEBUG_ERRORS
bool "Verbose kernel error messages"
depends on DEBUG_KERNEL
help
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.
# These options are only for real kernel hackers who want to get their hands dirty.
config DEBUG_LL
bool "Kernel low-level debugging functions"
depends on DEBUG_KERNEL
help
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.
