Embodiments relate to enabling software to interface with a power consumption telemetry system. A process may have tagging instructions that interface with an energy estimation engine. While the energy estimation engine is logging energy consumption by the process, the process may also mark, tag, or otherwise delineate periods of processing during the execution time of the process. The logic of the process may determine how such periods should be labeled and when they being and end. The tagged periods are correlated with energy consumed by the process so that details of what the process was doing during different periods of energy consumption may be understood.

Process-level activity tagging

In a device having a memory accessed as multiple pages, two or more pages of the multiple pages having identical content are identified. While the two or more pages are being identified, other processes running in the device are allowed to use the two or more pages, including being allowed to change cache attributes of each of the two or more pages. The two or more pages are combined into a single combined page (e.g., a newly allocated page of the multiple pages), and a process page record having multiple entries pointing to the multiple pages is updated so that entries that previously pointed to one of the two or more pages instead point to the single page.
