Linus Torvalds dcb4971018 - Extend the resctrl machinery to support telemetry monitoring on Intel. The
practical usage of this is being able to tell how much energy or how much
   work can be attributed to a group of tasks tracked under a single
   idenitifier. Prepend this work with proper refactoring of resctrl domains
   handling code. Work by Tony Luck
