nit: I'm guessing this is from:
64.0/(1024.0*1024.0) = 6.103515625e-05
and for reference:
64.0/(1000.0*1000.0) = 6.3999999999999997e-05
should the unit be MiB?
https://en.wikipedia.org/wiki/Kibibyte
Searching around I only see knightslanding using MiB but it seems to
be using it in the 1000^2 case which probably means it should be MB:
knightslanding/uncore-memory.json: "ScaleUnit": "6.4e-05MiB"
Given there is some confusion I wonder if it makes sense to just make
this 0.015625B and then we have a utility function that selects the
best unit for "bytes" with config options similar to --big-num?
Thanks,
Ian
