@ -84,6 +84,11 @@ per run to a respective 64-bit counter. The kernel thread starts
running during probe, wakes up every 100secs and stops running
when driver is removed.
Frequency of the accumulator thread is set during the probe
based on the chosen energy unit resolution. For example
A. fine grain (1.625 micro J)
B. course grain (0.125 milli J)
A socket and core energy read would return the current register
value added to the respective energy accumulator.
