The following chapters contain the most notable changes to kernel between RHEL 9 and RHEL 10.

15.1. Notable changes to kernel

The CFS Scheduler is replaced with EEVDF

The CFS Scheduler is replaced with a new scheduler, EEVDF.

This includes changes:

  • sched_min_granularity is now sched_base_slice and it uses the same unit.
  • sched_wakeup_granularity is unused in EEVDF and therefore it is removed.
