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 tools/power/x86/turbostat/Makefile | 2 +- tools/power/x86/turbostat/turbostat.c | 292 ++++++++++++++++++++++---- 2 files changed, 248 insertions(+), 46 deletions(-)
