Add a monitor for checking that real-time tasks do not go to sleep in a manner that may cause undesirable latency. Also change RV depends on TRACING to RV select TRACING to avoid the following recursive dependency: error: recursive dependency detected! symbol TRACING is selected by PREEMPTIRQ_TRACEPOINTS symbol PREEMPTIRQ_TRACEPOINTS depends on TRACE_IRQFLAGS symbol TRACE_IRQFLAGS is selected by RV_MON_SLEEP symbol RV_MON_SLEEP depends on RV symbol RV depends on TRACING Cc: John Ogness <john.ogness@linutronix.de> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Link: https://lore.kernel.org/75bc5bcc741d153aa279c95faf778dff35c5c8ad.1752088709.git.namcao@linutronix.de Reviewed-by: Gabriele Monaco <gmonaco@redhat.com> Signed-off-by: Nam Cao <namcao@linutronix.de> Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org>

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.
