5 config DEBUG_STACKOVERFLOW
6 bool "Check for stack overflows"
7 depends on DEBUG_KERNEL
9 This option will cause messages to be printed if free stack space
10 drops below a certain limit.
12 config DEBUG_STACK_USAGE
13 bool "Stack utilization instrumentation"
14 depends on DEBUG_KERNEL
16 Enables the display of the minimum amount of free stack which each
17 task has ever had available in the sysrq-T and sysrq-P debug output.
19 This option will slow down process creation somewhat.
21 config DEBUG_PAGEALLOC
22 bool "Debug page memory allocations"
23 depends on DEBUG_KERNEL && BROKEN
25 Unmap pages from the kernel linear mapping after free_pages().
26 This results in a large slowdown, but helps to find certain types
27 of memory corruptions.
30 bool "Compile the kernel with frame pointers"
32 If you say Y here the resulting kernel image will be slightly larger
33 and slower, but it will give very useful debugging information.
34 If you don't debug the kernel, you can say N, but we may not be able
35 to solve problems without frame pointers.
