Introduction
============
This regression tester is for the McPAT power model.
This tester can compile and runs McPAT on the input contained in the
specified directory, and then compares the output to that of a golden run in
order to ensure that specific power and area calculations do not change.
Nine tests are included in the initial version of this tester in the directories:
$GEM5/ext/mcpat/regression/test-*
In each directory, you will find a regression test input file
(power_region0.xml) and the golden-run output (region0.out.bak).
The tester's output file is saved as region0.out, which is then checked against
region0.out.bak.
Options
=======
--help, -h Show a help message and exit
--build, -b Build McPAT before running tests
--cleanup, -c Clean up the specified regression directory
--force, -f Force run regression even if directory isn't set up
--maketest, -m Set up the specified test directory
--verbose, -v Print verbose output
How to Use
==========
The regression tester must be invoked from the McPAT directory.
% cd $GEM5/ext/mcpat
To run all regression tests:
% ./regression/regression.py ./regression/
To run a particular regression test, specify its directory to the tester:
% ./regression/regression.py ./regression/test-0
Specify the "-v" option to see a diff of the regression output.
