Subject: [PATCH 0/3][RFC v2] tools/power turbostat: Enable accumulated energy consumption for long time sampling

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
