Hi, this series aims to provide a useful debug aid for running tests on the SCMI
subsystem. As you mentioned, ftrace does report some of these statistics,
however DEBUG_STATISTICS will allow a programatic interface to access the count
of failures, successes and an extended variety of other specific
errors/statistics for automated (or manual) testing.
Hope this clears things up,
Luke
