2019-03-19python: Switch to the new getPort mechanism to connect ports.Gabe Black
This retrieves ports using the getPort method, and connects them using the bind method on the ports themselves. Any smarts as far as what type of peers are allowed to connect or how they connect is left up to the individual bind methods.

2019-02-20python: Fix Param initialization issue in Python 3Andreas Sandberg
When initializing a param with a SimObject NULL pointer, convert() checks if the 'ptype' attribute has been created and whether the value is NULL. In that case, it assumes that the object is being initizalized as a part of SimObject initialization and defers the conversion. This check is implemented using hasattr() which in turn is implemented using the __getattr__ implementation that asserts because all SimObjects haven't been initialized yet. Implement the check using a lookup in the object's dictionary instead to prevent the SimObject lookup.

The appropriate value seems to depend on why some other bit of code is checking if there's a parent in the first place.

2017-05-31python: Fix unproxing of VectorParamsNikos Nikoleris
Previously proxy vector parameters would resolve correctly only for Parent.all. Any other proxy such as Parent.any, or exact ones such as Parent.addr_range would resolve to a *vector* of the right value resulting into a vector of a vector. For example if we set: DirectoryController0.addr_range = [0x100000-0x1fffff, 0x200000-0x2fffff] DirectoryMemory0.addr_range = Parent.addr_range where DirectoryController0 is the parent SimObject of DirectoryMemory0 after unproxying the Parent.addr_range VectorParam we would get DirectoryMemory0.addr_range = [[0x100000-0x1fffff, 0x200000-0x2fffff]] This change unifies handling of all three proxies to the same correct unproxy mechanism.

2017-05-02python: Use PyBind11 instead of SWIG for Python wrappersAndreas Sandberg
Use the PyBind11 wrapping infrastructure instead of SWIG to generate wrappers for functionality that needs to be exported to Python. This has several benefits: * PyBind11 can be redistributed with gem5, which means that we have full control of the version used. This avoid a large number of hard-to-debug SWIG issues we have seen in the past. * PyBind11 doesn't rely on a custom C++ parser, instead it relies on wrappers being explicitly declared in C++. The leads to slightly more boiler-plate code in manually created wrappers, but doesn't doesn't increase the overall code size. A big benefit is that this avoids strange compilation errors when SWIG doesn't understand modern language features. * Unlike SWIG, there is no risk that the wrapper code incorporates incorrect type casts (this has happened on numerous occasions in the past) since these will result in compile-time errors. As a part of this change, the mechanism to define exported methods has been redesigned slightly. New methods can be exported either by declaring them in the SimObject declaration and decorating them with the cxxMethod decorator or by adding an instance of PyBindMethod/PyBindProperty to the cxx_exports class variable. The decorator has the added benefit of making it possible to add a docstring and naming the method's parameters. The new wrappers have the following known issues: * Global events can't be memory managed correctly. This was the case in SWIG as well.

2014-10-16config: Add the ability to read a config file using C++ and PythonAndreas Hansson
This patch adds the ability to load in config.ini files generated from gem5 into another instance of gem5 built without Python configuration support. The intended use case is for configuring gem5 when it is a library embedded in another simulation system. A parallel config file reader is also provided purely in Python to demonstrate the approach taken and to provided similar functionality for as-yet-unknown use models. The Python configuration file reader can read both .ini and .json files. C++ configuration file reading: A command line option has been added for scons to enable C++ configuration file reading: --with-cxx-config There is an example in util/cxx_config that shows C++ configuration in action. util/cxx_config/README explains how to build the example. Configuration is achieved by the object CxxConfigManager. It handles reading object descriptions from a CxxConfigFileBase object which wraps a config file reader. The wrapper class CxxIniFile is provided which wraps an IniFile for reading .ini files. Reading .json files from C++ would be possible with a similar wrapper and a JSON parser. After reading object descriptions, CxxConfigManager creates SimObjectParam-derived objects from the classes in the (generated with this patch) directory build/ARCH/cxx_config CxxConfigManager can then build SimObjects from those SimObjectParams (in an order dictated by the SimObject-value parameters on other objects) and bind ports of the produced SimObjects. A minimal set of instantiate-replacing member functions are provided by CxxConfigManager and few of the member functions of SimObject (such as drain) are extended onto CxxConfigManager. Python configuration file reading (configs/example/read_config.py): A Python version of the reader is also supplied with a similar interface to CxxConfigFileBase (In Python: ConfigFile) to config file readers. The Python config file reading will handle both .ini and .json files. The object construction strategy is slightly different in Python from the C++ reader as you need to avoid objects prematurely becoming the children of other objects when setting parameters. Port binding also needs to be strictly in the same port-index order as the original instantiation.

As part of this renaming, the code has also been clean up slightly, making use of range-based for loops and tidying up some comments. The only changes outside the bus/crossbar code is due to the delay variables in the packet. --HG-- rename : src/mem/Bus.py => src/mem/XBar.py rename : src/mem/coherent_bus.cc => src/mem/coherent_xbar.cc rename : src/mem/coherent_bus.hh => src/mem/coherent_xbar.hh rename : src/mem/noncoherent_bus.cc => src/mem/noncoherent_xbar.cc rename : src/mem/noncoherent_bus.hh => src/mem/noncoherent_xbar.hh rename : src/mem/bus.cc => src/mem/xbar.cc rename : src/mem/bus.hh => src/mem/xbar.hh

This patch 'completes' .json config files generation by adding in the SimObject references and String-valued parameters not currently printed. TickParamValues are also changed to print in the same tick-value format as in .ini files. This allows .json files to describe a system as fully as the .ini files currently do. This patch adds a new function config_value (which mirrors ini_str) to each ParamValue and to SimObject. This function can then be explicitly changed to give different .json and .ini printing behaviour rather than being written in terms of ini_str.

2013-08-19power: Add voltage domains to the clock domainsAkash Bagdia
This patch adds the notion of voltage domains, and groups clock domains that operate under the same voltage (i.e. power supply) into domains. Each clock domain is required to be associated with a voltage domain, and the latter requires the voltage to be explicitly set. A voltage domain is an independently controllable voltage supply being provided to section of the design. Thus, if you wish to perform dynamic voltage scaling on a CPU, its clock domain should be associated with a separate voltage domain. The current implementation of the voltage domain does not take into consideration cases where there are derived voltage domains running at ratio of native voltage domains, as with the case where there can be on-chip buck/boost (charge pumps) voltage regulation logic. The regression and configuration scripts are updated with a generic voltage domain for the system, and one for the CPUs.

This patch removes the multiplication operator support for Clock parameters as this functionality is now achieved by creating derived clock domains. Nate, this one is for you.
