help
Write kernel log output directly into the VGA buffer or to a serial
port.
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 and doesn't cooperate
with klogd/syslogd or the X server. You should normally N here,
unless you want to debug such a crash.
config DEBUG_STACKOVERFLOW
bool "Check for stack overflows"
depends on DEBUG_KERNEL
help
This option will cause messages to be printed if free stack space
drops below a certain limit.
config 16KSTACKS
bool "Use 16Kb for kernel stacks instead of 8Kb"
help
If you say Y here the kernel will use a 16Kb stacksize for the
kernel stack attached to each process/thread. The default is 8K.
This increases the resident kernel footprint and will cause less
threads to run on the system and also increase the pressure
on the VM subsystem for higher order allocations.
