2016-11-09style: [patch 3/22] reduce include dependencies in some headersBrandon Potter
Used cppclean to help identify useless includes and removed them. This involved erroneously included headers, but also cases where forward declarations could have been used rather than a full include.
2016-06-06sim: Adding support for power modelsDavid Guillen Fandos
This patch adds some basic support for power models in gem5. The power interface is defined so it can interact with thermal models as well. It implements a simple power evaluator that can be used for simple power models that express power in the form of a math expression. These expressions can use stats within the same SimObject (or down its hierarchy) and some magic variables such as "temp" for temperature. In future patches we will extend this functionality to allow slightly more complex expressions. The model allows it to be extended to use other kinds of models.

It implements a simple power evaluator that can be used for simple power models that express power in the form of a math expression. These expressions can use stats within the same SimObject (or down its hierarchy) and some magic variables such as "temp" for temperature. In future patches we will extend this functionality to allow slightly more complex expressions. The model allows it to be extended to use other kinds of models. Finally, the thermal model is updated to use the power usage as input.
2015-05-12sim: Adding thermal model supportDavid Guillen Fandos
This patch adds basic thermal support to gem5. It models energy dissipation through a circuital equivalent, which allows us to use RC networks. This lays down the basic infrastructure to do so, but it does not "work" due to the lack of power models. For now some hardcoded number is used as a PoC. The solver is embedded in the patch.
2014-08-10config: Add SubSystem container for simobjectsGeoffrey Blake
This patch adds the SubSystem container for grouping simobjects together in logical subsystems to facilitate building a larger system from constituent parts. The container is simply a non-abstract empty simobject to hold the components that will be connected as its children. In simulation the object does not participate, its only use is during configuration of the system.
