Hi, perf hackers
I have other question.
As I know, perf also supports RAPL(running average power limit )
for power consumption measurements.
And as I understand, the amount of power consumption is estimated
by using hardware performance counters and I/O models (sure, in
availableintel CPUs).
And I've not found power consumption measurements for ARM (likeCortex-A9)
except for using tools like ARM Energy Probes and Linux EAPTools.
But as I know , The Cortex-A9 Core Platform has dynamic scaling
ofvoltage and frequency.
(Dynamic Voltage and Frequency Scaling (DVFS))
Have you ever tried to measure power consumption on ARM using thingslike
DVFS?
and I also wonder how to use perf to measure power consumption on
available intel CPU.
