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. -- R. Kevin Oberman, Network Engineer, Retired E-mail: rkoberman@gmail.com
