    perf tools: Add a per tracepoint counter attribute to get raw sample · 3a9f131f
    Frederic Weisbecker authored
    Add a new flag field while opening a tracepoint perf counter:
    
    	-e tracepoint_subsystem:tracepoint_name:flags
    
    This is intended to be generic although for now it only supports the
    r[e[c[o[r[d]]]]] flag:
    
    	./perf record -e workqueue:workqueue_insertion:record
    	./perf record -e workqueue:workqueue_insertion:r
    
    will have the same effect: enabling the raw samples record for
    the given tracepoint counter.
    
    In the future, we may want to support further flags, separated
    by commas.
