OK. Any documentation on what this is supposed to tell me? Some of it makes
perfect sense and some baffles me.

I see C-states of C1 and C6 when on AC and C1, C3, and C7 when on battery
(and, of course, C0). FREQ vs. AFREQ look interesting, but I'm not sure I
really understand the implications. The last few lines, from " PHYSICAL
CORE IPC", are particularly mysterious to me. I can understand the words,
but I think that they carry more significance than is obvious, at least to
me. I'm not a hardware guy.
