The RAPL Joule Counter is 32 bit, turbostat would only print a *star* instead of printing the actual energy consumed due to the overflow of RAPL register.
Introduce the accumulated RAPL mechanism to avoid the possible overflow.
Chen Yu (3): tools/power turbostat: Make the energy variable to be 64 bit tools/power turbostat: Introduce functions to accumulate RAPL consumption tools/power turbostat: Enable accumulate RAPL display
