- 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.
