menu "Kernel hacking"
source "lib/Kconfig.debug"
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 DEBUG_STACK_USAGE
bool "Stack utilization instrumentation"
depends on DEBUG_KERNEL
help
Enables the display of the minimum amount of free stack which each
task has ever had available in the sysrq-T and sysrq-P debug output.
This option will slow down process creation somewhat.
config DEBUG_PAGEALLOC
bool "Page alloc debugging"
depends on DEBUG_KERNEL
help
Unmap pages from the kernel linear mapping after free_pages().
This results in a large slowdown, but helps to find certain types
of memory corruptions.
config FRAME_POINTER
bool "Compile the kernel with frame pointers"
help
If you say Y here the resulting kernel image will be slightly larger
and slower, but it will give very useful debugging information.
If you don't debug the kernel, you can say N, but we may not be able
to solve problems without frame pointers.
