Sergei Trofimov	485ba419b3	energy_model: set matplotlib backent to AGG ... Matplotlib defautls to the GTK backend. This can cause problems when running in a headless session (e.g. over SSH). Since energy_model istrument generates PNG plots, rather than rendering directly to UI, it doesn't actually need GTK; set backend to AGG so that energy_model works in headless environments.	2015-05-11 12:12:41 +01:00
Sergei Trofimov	68ae8b9277	energy_model: added energy_metric ... It is now possible to specify energy_metric instead of power_metric for cases where continuous power is not available but energy can be measured.	2015-05-11 12:12:41 +01:00
Sergei Trofimov	9d5e0cdc00	Fixing pylint false positives in energy_model ... The new version of pylint is throwing up a couple of new false positives that the earlier versions did not seem to flag.	2015-05-11 12:12:41 +01:00
Sergei Trofimov	841bd784d9	Fix: correctly set measured/measuring cores.	2015-05-11 12:12:41 +01:00
Sergei Trofimov	47ce9db383	Updating energy model instrument to be able to accumulate multiple power rails for each cluster.	2015-05-11 12:12:40 +01:00
Sergei Trofimov	c52d562411	Adding energy_model instrument. ... This instrument can be used to generate an energy model for a device based on collected power and performance measurments. The instrument produces a C file with an energy model and an accompanying HTML report. This instrument is very different from other instrumentation, as it actually generates the run queue on the fly based on the operating frequencies and idle states it discovers on the device. The agenda needs only to contain the single "base" spec that defines the workload to be used for performance measurement.	2015-05-11 12:12:40 +01:00
