2018-08-24cpu: Stream/SubstreamID support in TrafficGenGiacomo Travaglini
This patch is adding support for generating memory requests which set the StreamID/SubstreamID field, so that is possible to emulate devices attached to an external IOMMU/SMMU with a Traffic generator.

2018-08-22mem: Add StreamID and SubstreamIDStanislaw Czerniawski
This patch adds StreamID and SubstreamID to Request. These fields can be used by a SMMU/IOMMU model to pick up the correct translation context for each request and they correspond to an ASID in a device. For this reason they have been merged together with the request asid in a union, so that a cpu will set the asid and a device will set the Stream and Substream ID.

The tests were referring to constants defined in the Accellera systemc implementation which identified various log message types. This change replaces those (sometimes quite long) string constants with their actual value. This doesn't make that interface any more fragile since the constant value won't track between the Accellera version and this one, but it does make its fragility more explicit by using the value directly. If in the future we decide to hide the magical nature of those particular string constants, we could make them into our own constants in the implementation.

The systemc spec says that sc_bind, sc_ref and sc_cref macros should expand to boost::bind, boost::ref, and boost::cref respectively, but that it's "use is not mandantory". Unfortunately, the regression tests use those macros without actually including the boost headers for themselves, and so they won't compile without dragging in these boost headers as a dependency. This should be mostly ok to include here since gem5 itself shouldn't include systemc, just the sub headers that systemc brings in. systemc code which includes systemc *will* have a dependency on boost, but that at least contains the new dependency somewhat.

Also it should be noted that the systemc spec is incorrect where it defines these classes. When implemented like they are in the Accellera version, the versions of bind in sc_vector_assembly which take sc_vector<T>::iterator and iterator parameters are different, and so they can overload each other. If implemented as described by the spec however, those types are the same and the code won't compile.

2018-08-15systemc: Make a test stop including an internal path for sc_vector.Gabe Black
The sc_vector class is available through systemc.h already, so there's no reason to include an internal path which is only there on Accellera by coincidence of the implementation.

2018-08-15systemc: Add a script which automates building and running tests.Gabe Black
The only required option for the script is the path to a build directory, for instance build/ARM. It uses that when running scons and when referring to generated files (like the built versions of the tests). It uses the location of the script itself to find source files, like the "golden" version of outputs. This script runs tests in three phases, compilation, running, and then verification. By default, all three phases are run for all tests, but which phases run and how they work can be customized by specifying them explicitly on the command line with the --phase option. Each time the --phase option shows up on the command line, it should be followed by the name of the phase being specified. That both declares that that phase should be run, and also that any subsequent options apply to that phase, at least until the next --phase option. Currently, only the "compile" and "execute" phases are implemented, and only the "compile" phase has been tested at all or has any options defined. The "compile" phase simply takes all the options it was given and pass them on to scons. The "verify" phase simply prints a message which says what it would have verified. The script can list the available tests with the --list option, as determined by the json systemc test manifest file which scons can generate, and which the script can refresh if passed the --update-json option. You can also specify what "flavor" of build you want to do, ie opt, debug, fast, etc., with the --flavor option. Only one flavor can be tested at a time, but that should be the desired behavior most of the time. If multiple flavors need to be tested, the script can be invoked multiple times. Finally, there is a --filter option which accepts a python expression as a string. That expression is evaluated in the namespace of the properties of each test in the json file, and if it returns true then that test is run. For instance, to verify only compile_only tests, you would use: systemc/tests/verify.py build/ARM --filter 'compile_only' To test only compile_only tests named bob, you would run this: systemc/tests/verify.py build/ARM --filter \ 'compile_only && name ="bob"' Also included is a simple config.py which is the beginning of a config which will run the systemc regression tests. Right now, all it knows how to do is run sc_main.
