2016-10-19stats: Update stats to reflect recent changes to floatsAndreas Hansson
Mostly just splitting out the floats ops and corresponding reads/writes.
2016-10-14config: Make configs/common a Python packageAndreas Hansson
Continue along the same line as the recent patch that made the Ruby-related config scripts Python packages and make also the configs/common directory a package. All affected config scripts are updated (hopefully). Note that this change makes it apparent that the current organisation and naming of the config directory and its subdirectories is rather chaotic. We mix scripts that are directly invoked with scripts that merely contain convenience functions. While it is not addressed in this patch we should follow up with a re-organisation of the config structure, and renaming of some of the packages.

2016-10-13ruby: Fix regressions and make Ruby configs Python packagesAndreas Hansson
This patch moves the addition of network options into the Ruby module to avoid the regressions all having to add it explicitly. Doing this exposes an issue in our current config system though, namely the fact that addtoPath is relative to the Python script being executed. Since both example and regression scripts use the Ruby module we would end up with two different (relative) paths being added. Instead we take a first step at turning the config modules into Python packages, simply by adding a __init__.py in the configs/ruby, configs/topologies and configs/network subdirectories. As a result, we can now add the top-level configs directory to the Python search path, and then use the package names in the various modules. The example scripts are also updated, and the messy path-deducing variations in the scripts are unified.

2016-09-16tests: Add support for functional only testsAndreas Sandberg
Modify the ClassicTest class to only emit a stat verification test unit if there is a reference stat file. This makes it possible to design tests that don't care about stat changes. To generate purely functional tests, we need to be able to create empty test reference directories. This does not work well with many revision control systems. As a workaround, add a file named EMPTY to the list of ignored files in the test harness. This file can be used as a placeholder in otherwise empty test directories.

2016-06-20tests: Add a test command to get test status as an exit codeAndreas Sandberg
Add a "test" command to tests.py that queries a test pickle file and returns different exit codes depending on the outcome of the tests in the file. The following exit codes can currently be returned: * 0: All tests were successful or skipped. * 1: General fault in the script such as incorrect parameters or failing to parse a pickle file. * 2: At least one test failed to run. This is what the summary formatter usually shows as a 'FAILED'. * 3: All tests ran correctly, but at least one failed to verify its output. When displaying test output using the summary formatter, such a test would show up as 'CHANGED'. The command can be invoked like this: ./tests/tests.py test `find build/ARM/tests/opt/ -name status.pickle` Change-Id: I7e6bc661516f38ff08dfda7c4359a1e10bf97864 Signed-off-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com>

2016-06-20mem: Resolve TrafficGen trace relative to the configAndreas Sandberg
The traffic generator currently resolves relative trace paths relative to gem5's current working directory. This can lead to surprising results for relative paths where the expectation would normally be that they are resolved relative to the configuration file. This changeset implements config-relative trace file lookups. The old behavior is kept as a fallback for configs that expect that behavior.

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>

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.
