	The following patches had unexpected interactions with the current upstream code and have been reverted for now: e07fd01651f3: power: Add support for power models 831c7f2f9e39: power: Low-power idle power state for idle CPUs 4f749e00b667: power: Add power states to ClockedObject Signed-off-by: Andreas Sandberg <andreas.sandberg@arm.com> --HG-- extra : amend_source : 0b6fb073c6bbc24be533ec431eb51fbf1b269508
2016-04-05	power: Add support for power models	David 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. Finally, the thermal model is updated to use the power usage as input.

	This patch contains a new CPU model named `Minor'. Minor models a four stage in-order execution pipeline (fetch lines, decompose into macroops, decompose macroops into microops, execute). The model was developed to support the ARM ISA but should be fixable to support all the remaining gem5 ISAs. It currently also works for Alpha, and regressions are included for ARM and Alpha (including Linux boot). Documentation for the model can be found in src/doc/inside-minor.doxygen and its internal operations can be visualised using the Minorview tool utils/minorview.py. Minor was designed to be fairly simple and not to engage in a lot of instruction annotation. As such, it currently has very few gathered stats and may lack other gem5 features. Minor is faster than the o3 model. Sample results: Benchmark \| Stat host_seconds (s) ---------------+--------v--------v-------- (on ARM, opt) \| simple \| o3 \| minor \| timing \| timing \| timing ---------------+--------+--------+-------- 10.linux-boot \| 169 \| 1883 \| 1075 10.mcf \| 117 \| 967 \| 491 20.parser \| 668 \| 6315 \| 3146 30.eon \| 542 \| 3413 \| 2414 40.perlbmk \| 2339 \| 20905 \| 11532 50.vortex \| 122 \| 1094 \| 588 60.bzip2 \| 2045 \| 18061 \| 9662 70.twolf \| 207 \| 2736 \| 1036
