source "lib/Kconfig.debug"
config DEBUG_STACK_USAGE
bool "Enable 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 KPROBES
bool "Kprobes"
depends on DEBUG_KERNEL
help
Kprobes allows you to trap at almost any kernel address and
execute a callback function. register_kprobe() establishes
a probepoint and specifies the callback. Kprobes is useful
for kernel debugging, non-intrusive instrumentation and testing.
If in doubt, say "N".
config DEBUG_DCFLUSH
bool "D-cache flush debugging"
depends on DEBUG_KERNEL
config STACK_DEBUG
depends on DEBUG_KERNEL
bool "Stack Overflow Detection Support"
config DEBUG_BOOTMEM
depends on DEBUG_KERNEL
bool "Debug BOOTMEM initialization"
config DEBUG_PAGEALLOC
bool "Page alloc debugging"
depends on DEBUG_KERNEL && !SOFTWARE_SUSPEND
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.
