Subject: [PATCH 0/3][RFC v2] tools/power turbostat: Enable accumulated energy consumption for long time sampling
Date: Tue, 14 Apr 2020 20:56:21 +0800 [thread overview]
Message-ID: <cover.1586782089.git.yu.c.chen@intel.com> (raw)
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
