17	help
18	  Enable the kernel runtime verification infrastructure. RV is a
19	  lightweight (yet rigorous) method that complements classical
20	  exhaustive verification techniques (such as model checking and
21	  theorem proving). RV works by analyzing the trace of the system's
22	  actual execution, comparing it against a formal specification of
23	  the system behavior.

47	  sample monitor that illustrates the usage of per-task monitor.
48	  The model is borken on purpose: it serves to test reactors.

56	depends on RV
57	help
58	  Enables the online runtime verification reactors. A runtime
59	  monitor can cause a reaction to the detection of an exception
60	  on the model's execution. By default, the monitors have
61	  tracing reactions, printing the monitor output via tracepoints,
62	  but other reactions can be added (on-demand) via this interface.

64config RV_REACT_PRINTK
65	bool "Printk reactor"
66	depends on RV_REACTORS
67	default y
68	help
69	  Enables the printk reactor. The printk reactor emits a printk()
70	  message if an exception is found.

77	  Enables the panic reactor. The panic reactor emits a printk()
78	  message if an exception is found and panic()s the system.
