H A DMathExprPowerModel.py11527:9007a9729815 Mon Jun 06 12:16:00 EDT 2016 David Guillen Fandos <david.guillen@arm.com> sim: Adding support for power models

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.

This makes those files more consistent with other headers in gem5. The
top level headers (tlm and tlm.h) and the tlm_utils headers were left
alone since the user might reasonably expect those to have a well known
name. The tlm_core headers by comparison are an implementation detail,
and users shouldn't include them directly by name.

This patch adds explicit overrides as this is now required when using

where "override" is added. The latter should be enough of an
indication.

As part of this patch, a few minor issues that clang >= 3.5 complains
about are also resolved (unused methods and variables).

The void * type is for pointers which point to an unknown type. We
should use that when handling anonymous buffers in the PortProxy
functions, instead of uint8_t * which points to bytes.

Importantly, C/C++ doesn't require you to do any casting to turn an
arbitrary pointer type into a void *. This will get rid of lots of
tedious, verbose casting throughout the code base.
