menu "Kernel hacking" source "lib/Kconfig.debug" 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
