menuconfig KERNEL_TESTS
	bool "Kernel subsystem tests"
	help
	  You can build kernel subsystem specific tests.

if KERNEL_TESTS

config DEBUG_LOCKING_API_SELFTESTS
	bool "Locking API boot-time self-tests"
	depends on DEBUG_KERNEL
	help
	  Say Y here if you want the kernel to run a short self-test during
	  bootup. The self-test checks whether common types of locking bugs
	  are detected by debugging mechanisms or not. (if you disable
	  lock debugging then those bugs wont be detected of course.)
	  The following locking APIs are covered: spinlocks, rwlocks,
	  mutexes and rwsems.

config RCU_TORTURE_TEST
	tristate "torture tests for RCU"
	depends on DEBUG_KERNEL
	default n
	help
	  This option provides a kernel module that runs torture tests
	  on the RCU infrastructure.  The kernel module may be built
	  after the fact on the running kernel to be tested, if desired.

	  Say Y here if you want RCU torture tests to be built into
	  the kernel.
	  Say M if you want the RCU torture tests to build as a module.
	  Say N if you are unsure.

config RCU_TORTURE_TEST_RUNNABLE
	bool "torture tests for RCU runnable by default"
	depends on RCU_TORTURE_TEST = y
	default n
	help
	  This option provides a way to build the RCU torture tests
	  directly into the kernel without them starting up at boot
	  time.  You can use /proc/sys/kernel/rcutorture_runnable
	  to manually override this setting.  This /proc file is
	  available only when the RCU torture tests have been built
	  into the kernel.

	  Say Y here if you want the RCU torture tests to start during
	  boot (you probably don't).
	  Say N here if you want the RCU torture tests to start only
	  after being manually enabled via /proc.

config RT_MUTEX_TESTER
	bool "Built-in scriptable tester for rt-mutexes"
	depends on DEBUG_KERNEL && RT_MUTEXES
	help
	  This option enables a rt-mutex tester.

config LKDTM
	tristate "Linux Kernel Dump Test Tool Module"
	depends on DEBUG_KERNEL
	depends on KPROBES
	depends on BLOCK
	default n
	help
	This module enables testing of the different dumping mechanisms by
	inducing system failures at predefined crash points.
	If you don't need it: say N
	Choose M here to compile this code as a module. The module will be
	called lkdtm.

	Documentation on how to use the module can be found in
	drivers/misc/lkdtm.c

config KPROBES_SANITY_TEST
	bool "Kprobes sanity tests"
	depends on DEBUG_KERNEL
	depends on KPROBES
	default n
	help
	  This option provides for testing basic kprobes functionality on
	  boot. A sample kprobe, jprobe and kretprobe are inserted and
	  verified for functionality.

	  Say N if you are unsure.

config BACKTRACE_SELF_TEST
	tristate "Self test for the backtrace code"
	depends on DEBUG_KERNEL
	default n
	help
	  This option provides a kernel module that can be used to test
	  the kernel stack backtrace code. This option is not useful
	  for distributions or general kernels, but only for kernel
	  developers working on architecture code.

	  Note that if you want to also test saved backtraces, you will
	  have to enable STACKTRACE as well.

	  Say N if you are unsure.
