Add a per-cpu monitor as part of the sched model:
* opid: operations with preemption and irq disabled
Monitor to ensure wakeup and need_resched occur with irq and
preemption disabled or in irq handlers.

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

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