2019-06-19python: Add support for exporting static class methods from c++Nikos Nikoleris
This change adds support for exporting static methods in a c++ SimObject from the coressponsing python wrapper class. This will allow us to define and use c++ methods without the need to instantiate an object of the corresponding class.

2019-02-20config: Make parameter conversion handle integers in other bases.Gabe Black
Python's float() function/type can't handle hexadecimal notation, but int() can. Since there are also cases where converting to a float and then back to an int (or long) can cause rounding error, this change splits toFloat and toInteger apart and makes them call a worker function which accepts a conversion function which does the work of converting a numeric string into an actual number. in the case of toFloat, it still uses the standard float(), and in the case of toInteger it uses a lambda which wraps int(x, 0).

Note to not import both the pyfdt and fdthelper in the same namespace (but generally fdthelper is all you need, because it supplies the same classes even when they are not extended in any way) Also, this patch lays out the primary functionality for generating a device tree, where every SimObject gets an empty generateDeviceTree method and ArmSystems loop over their children in an effort to merge all the nodes. Devices are implemented in other patches.

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.

2015-12-15misc: Add secondary dot output for DVFS domainsSascha Bischoff
This patch adds a secondary dot output file which shows the DVFS domains. This has been done separately for now to avoid cluttering the already existing diagram. Due to the way that the clock domains are assigned to components in gem5, this output must be generated after the C++ objects have been instantiated. This further motivates the need to generate this file separately to the current dot output, and not to replace it entirely.

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.
