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.
