1088003135 tests: Only run Ruby tests when testing Ruby targets
Limit the test configs to Ruby-only configs when testing a Ruby target
that isn't MI_example. This avoids re-running configs that has already
been tested by the generic (non-Ruby) ISA target. This behavior was
the expected behavior prior to switching to the new test framework.

44e9b81f74 scons: Use the new test framework from scons
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

dbf64aa2c2 tests: Fix incorrect stat.txt ignore when updating refs
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.

71a02f624e mem, config: Selective use of snoop filter
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.

f385adc8af tests: Add test infrastructure as a Python module
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

cabd4768c7 cpu: Fix LLSC atomic CPU wakeup
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.

3840a72f37 stats: more updates due to PCI changes
A couple of the long regressions have been showing as CHANGED

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?).
