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
