2016-05-31scons: Use the new test framework from sconsAndreas Sandberg
Rewrite the SCons script responsible for launching tests to use the new test framework. The biggest visible change after this changeset is that SCons no longer produces a "status" file in test build directories. Instead, it creates a status.pickle file. That file can be inspected using the new tests.py script. Another visible change is that timed out tests are now reported as failed rather than a using a separate summary message. Since the pickle file will remain in the build directory after running tests, it's now possible to convert the test results into other formats. For example: ./tests/tests.py show --format junit -o junit.xml \ `find build/ -name status.pickle` To better facilitate running outside of scons, there is now a set of targets that generate test listings that can be used by the test script. There are currently three targets, quick.list, long.list, and all.list. For example: scons build/ARM/tests/opt/all.list for F in `cat build/ARM/tests/opt/all.list`; do ./tests/tests.py run build/ARM/gem5.opt $F done Change-Id: I2c0f8ca0080d7af737362e198eda4cb3a72e6c36 Signed-off-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com>
2016-05-31tests: Fix incorrect stat.txt ignore when updating refsAndreas Sandberg
ClassicTest was incorrectly ignoring stats.txt when updating reference statistics. This was caused by ignore rules being applied too aggressively when listing reference files. This changeset splits the ignore rules into two different lists: 1) diff_ignore_files that lists the files that shouldn't be diff:ed using the normal diff tool, and 2) ref_ignore_files which lists files that should be ignored by the test system.

2016-05-27mem, config: Selective use of snoop filterStephan Diestelhorst
Disable the default snoop filter in the SystemXBar so that the typical membus does not have a snoop filter by default. Instead, add the snoop filter only when there are caches added to the system (with the caches / l2cache options). The underlying problem is that the snoop filter grows without bounds (for now) if there are no caches to tell it that lines have been evicted. This causes slow regression runs for all the atomic regressions. This patch fixes this behaviour. --HG-- extra : source : f97c20511828209757440839ed48d741d02d428f
2016-05-26tests: Add test infrastructure as a Python moduleAndreas Sandberg
Implement gem5's test infrastructure as a Python module and a run script that can be used without scons. The new implementation has several features that were lacking from the previous test infrastructure such as support for multiple output formats, automatic runtime tracking, and better support for being run in a cluster environment. Tests consist of one or more steps (TestUnit). Units are run in two stages, the first a run stage and then a verify stage. Units in the verify stage are automatically skipped if any unit run stage wasn't run. The library currently contains TestUnit implementations that run gem5, diff stat files, and diff output files. Existing tests are implemented by the ClassicTest class and "just work". New tests can that don't rely on the old "run gem5 once and diff output" strategy can be implemented by subclassing the Test base class or ClassicTest. Test results can be output in multiple formats. The module currently supports JUnit, text (short and verbose), and Python's pickle format. JUnit output allows CI systems to automatically get more information about test failures. The pickled output contains all state necessary to reconstruct a tests results object and is mainly intended for the build system and CI systems. Since many JUnit parsers parsers assume that test suite names look like Java package names. We currently output path-like names with slashes separating components. Test names are translated according to these rules: * '.' -> '-" * '/' -> '.' The test tool, tests.py, supports the following features: * Test listing. Example: ./tests.py list arm/quick * Running tests. Example: ./tests.py run -o output.pickle --format pickle \ ../build/ARM/gem5.opt \ quick/se/00.hello/arm/linux/simple-timing * Displaying pickled results. Example: ./tests.py show --format summary *.pickle Change-Id: I527164bd791237aacfc65e7d7c0b67b695c5d17c Signed-off-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com> Reviewed-by: Joel Hestness <jthestness@gmail.com>
2016-05-09tests: Enable test running outside of gem5's source treeAndreas Sandberg

2016-05-07tests: update EIO ref stats for removed cache statsSteve Reinhardt
Complaints about changes in EIO tests were due to reference files that still have removed cache stats from cset 11454:e55afadc4e19.
2016-04-28tests: Remove stale reference output filesAndreas Sandberg
Remove test reference files that are not generated any more: * chair.cook.ppm: This file should be generated by eon and not mcf, so it shouldn't be included as an output from mcf. * system.pc.terminal: The terminal device has been renamed so this file is no longer generated.

2015-07-19cpu: Fix LLSC atomic CPU wakeupKrishnendra Nathella
Writes to locked memory addresses (LLSC) did not wake up the locking CPU. This can lead to deadlocks on multi-core runs. In AtomicSimpleCPU, recvAtomicSnoop was checking if the incoming packet was an invalidation (isInvalidate) and only then handled a locked snoop. But, writes are seen instead of invalidates when running without caches (fast-forward configurations). As as simple fix, now handleLockedSnoop is also called even if the incoming snoop packet are from writes.

2016-01-17stats: update SPARC FS statsSteve Reinhardt
The fs/80.solaris-boot/sparc/solaris/t1000-simple-atomic test was broken for so long that, now that it's working again, the stats output is out of date. This changeset updates the outputs, on the assumption that the stats changes are all valid differences due to other changes made while it was broken.
2015-12-30stats: more updates due to PCI changesSteve Reinhardt
A couple of the long regressions have been showing as CHANGED since 11244:a2af58a06c4e despite the updates in 11245:1c5102c0a7a9. The x86 regression looks like it was just missed, but it's not clear why the ARM one is giving different results (perhaps a non-determinism between zizzer and wherever the updated results were run?).
