Hi Len, I tested out these patches on an IvyBridge system and see the new Watts fields. They look like reasonable numbers to me. I ran with the system idle and then with lookbusy -c 50 and saw the Watts increase. Is there anything else to do to validate the numbers? In one case I saw that the Pkg_W for the system was off by .01, e.g. socket 0 was 28.33 and socket 1 was 29.74 and the system total was 58.08 instead of 58.07. That is probably fine and just rounding up. -Betty
