Carbon measurement and energy attribution for processes and hardware devices in the Linux kernel

This talk details the recent carbon measurement infrastructure developments in power subsystems in the Linux kernel. The objective is to determine the energy consumption and link it to carbon emissions of hardware devices and software applications (processes). This infrastructure allows the programmers and users to see which hardware devices and processes are responsible for the system's energy consumption and carbon emissions. These statistics are extremely useful for both user-level applications and kernel developers.

Major objectives in this talk would include a detailed discussion on the development of the required infrastructure and multivariate regression models to determine application and hardware device energy consumption. FOSSDEM would be a great platform to present the work done so far to the open-source software developer community and get feedback to further improve and fine-tune models toward better predictions. There are also privacy concerns attached to this data, which need feedback from more developers.
