""" This utility can be used to debug and tune the performance of the
intel_pstate driver. This utility can be used in two ways:
- If there is Linux trace file with pstate_sample events enabled, then
this utility can parse the trace file and generate performance plots.
- If user has not specified a trace file as input via command line parameters,
then this utility enables and collects trace data for a user specified interval
and generates performance plots.
Prerequisites:
Python version 2.7.x
gnuplot 5.0 or higher
gnuplot-py 1.8
(Most of the distributions have these required packages. They may be called
gnuplot-py, phython-gnuplot. )
HWP (Hardware P-States are disabled)
Kernel config for Linux trace is enabled
