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 "Debug page memory allocations" depends on DEBUG_KERNEL && BROKEN 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. endmenu
