Hmm, so I'm looking at builtin-stat.c::print_interval() and since
it gets the perf_evsel counters and you can deduce the counter name
from it, you probably could match the rapl counters and do the Watts
conversion above as a special case.
I dunno, it is much better than having some naked numbers for which
people have to go stare at the sources + CPU vendor docs as to what they
actually mean.
Thanks.
