- 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.
