Red Hat Enterprise Linux 9 changes in the context of Red Hat OpenShift workloads
Red Hat Enterprise Linux 9 (RHEL) introduced several interesting changes to the underlying Red Hat OpenShift platform (RHEL Core OS). Most of the workloads should be fine, and the underlying platform will handle the differences, but some advanced workloads might need the extra knowledge that I present here.
Workloads that need to adapt to the changes will typically share some activity patterns, like autodetection of assigned CPUs, dynamic management of thread-to-CPUs assignment, advanced system introspection via cgroups and/or dynamic power management.
