LIS25-132 Rework Energy Aware Scheduling

Technical presentation - 30 minutes (including q&a)

Linux kernel

  • Wednesday, 14 May 15:00 - 15:25
  • Room: Session room 2 | Opala I & II

Following OSPM'25 discussion, we will present the rework of the scheduler related to EAS that is under review on the mailing list. This includes the new push callback mechanism that adds more opportunity to migrate tasks across CPUs and the rework of energy estimation that includes new hints for the selection of CPUs in the same domain. We will also explore the new opportunities given by these changes to extend the CPU selection process to include new hints like the scheduling slice or some latency constraints and how to describe them.
