Added a parameter (_disk_device) to kernel_disk_workload which allows
users to change the disk device location. get_disk_device() now chooses
between the parameter and, if no parameter was passed, it calls a new
function _get_default_disk_device() which is implemented by each board
and has a default disk device according to each board, eg /dev/hda in
the x86_board. The previous way of setting a disk device still exists as
a default, however, with the new function users can now override this
default
This comment was left in the codebase in error. The
`set_se_binary_workload` function works fine with multi-threaded
applications. This hasn't been a restriction for some time.
- A new abstract BTB class is created to enable different BTB
implementations. The new BTB class gets its own parameter
and stats.
- An enum is added to differentiate branch instruction types.
This enum is used to enhance statistics and BPU management.
- The existing BTB is moved into `simple_btb` as default.
- An additional function is added to store the static instruction in
the BTB. This function is used for the decoupled front-end.
- Update configs to match new BTB parameters.

This enables two things,
- /chosen/stdout-path is now default to uart@10000000, meaning
the linux kernel's boot console will be redirected to uart.
- /chosen/bootargs now contains the boot arguments obtained from
gem5's library. This allows passing the boot arguments to the
linux kernel via the device tree.

I believe the point of this binary was to allow people to use the m5
objects without the entire gem5 binary. However, without adding the
importer call, this did not work. Unfortunately, with the importer call
there is a circular dependence on the original gem5py.cc file.
Therefore, this change creates a new file that has the importer call.
Now, with the `gem5py_m5` binary you can run python code that references
modules in `src/python`. Note that `_m5` is not available, so anything
that depends on the gem5 SimObjects' implementation will not work.
However, this can still be useful for things like getting Resources,
processing stats, etc.
The L3 cache did not work due to argument type mismatch in the call to
the constructor `DMAController`. The second argument is expecting a
`RubySystem` type but the code passes in a `cache_line_size` variable.
After I change the second argument to `self.ruby_system` everything
works.
This patch introduces a new category called "suite".
A suite is a collection of workloads.
Each workload in a SuiteResource has a tag that can be narrowed down
through the function with_input_group.
Also, the set of input groups can be seen through list_input_groups.
Added unit tests to test all functions of SuiteResource class.

By default, the `--stderr-file` and `--stdout-file` arguments were
directing the simulator to output files named "simerr" and "simout"
respectively if an output redirect was requested.
A small annoyance is these files lack an extension meaning programs
refuse to open them, or don't do so withou additional effort. On many
systems they are assumed to scripts.
This patch adds the `.txt` extension to both, thus clearly indicating to
other programs these are text files and can be opened and read as such.
This PR utilizes GitHub Action's matrix's to automatically distribute
the CI testlib gem5 build and test jobs across available GitHub Action
Runners.
The CI tests (the `quick` testlib tests, i.e. those run with `./main.py
run`) are distributed across the runners on a per directory basis ---
all directories under "tests/gem5" are run as their own jobs.
The necessary gem5 builds for each workflow are now automatically
inferred via the introduction of `./main.py list`'s `--build-targets`
flag which returns the gem5 build target for a given test or collection
of tests. E.g., `./main.py list --build-targets` will return the build
targets for all the `quick` testlib tests and `./main.py list
--build-target --uid=<id>` will return the build targets the test suite
`<id>` requires.
Moving from monolithic jobs to fine-grained ones will make the locaiton
of test failures more obvious. Each job has it's own artifact containing
"test/testing-results" for the tests run in that job. In addition,
maintenance of these files should become less burdensome due to less
hardcoding.
- Added mulitline string for print message
- Added get_category_name method instead of having category as variable

This allows us to generate stubs for the modules in gem5. The output
will be a "typings" directory which can be used by Pylance (Python
IntelliSense) to infer typings in Visual Studio Code.
Note: A "typings" directory in the root of the workspace is the default
location for Pylance to look for typings. This can be changed via
`python.analysis.stubPath` in "settings.json".
Usage
=====
```
pip3 install -r requirements.txt
scons build/ALL/gem5.opt -j$(nproc)
./build/ALL/gem5.opt util/gem5-stubgen.py

This allows for a user to specify the exact path they want a resource to
be downloaded to. This differs from 'resource_direcctory' in that a user
may specify the file/directory name of the resource (using just the
'resource_directory' will have the resource as its ID in that directory.

Python 3's `-P` flag, when set, means `sys.path` is not prepended with
potentially unsafe paths:
https://docs.python.org/3/using/cmdline.html#cmdoption-P
This patch allows gem5 to mimic this. This is necesssary when using
`mypy.stubgen` as it expects the Python Interpreter to have the `-P`
flag.

This patch allows a local JSON file to specify a local path
in the JSON object of a Resource, through the "url" field.
Local paths can be entered with the prefix "file:" in "url".
All File URI scheme formats are supported.
This behavior is the same as using specific Resource classes
(ex. BinaryResource) and passing a local_path into the function.
But, the above infrastructure does not allow simultaneous
creation of Resources and Workloads of those Resources.
With this patch, someone can use a local JSON, specify the location
of local Resources and create a Workload from those Resources and
test both together.
Also, this patch adds pyunit tests to check the functionality
of the function used to convert the "url" field into a path.
