<span class="quote">> It's measuring 60mW which would be close to idle non-rc6 power. (Estimating

For measurement solution:
The GFXWatt got from turbostat tool is a kind of RAPL(Running Average Power
Limit) power measurement solution, which should be reliable test method.
For workload:
My expected result is we should get different power consumption when I load
some workload comparing with idle scenario. I encountered problem is GFXwatt no
change whatever idle or other gfx workload. Pls correct and educate me if my
understanding is wrong, thanks!</pre>
