      * Previously, the `tuned` profile reported a `Degraded` condition after `PerformanceProfile` was applied. The profile had attempted to set a `sysctl` value for the default Receive Packet Steering (RPS) mask, but the mask was already configured with the same value using an `/etc/sysctl.d` file. With this update, the `sysctl` value is no longer set with the `tuned` profile and the issue has been resolved. (link:https://issues.redhat.com/browse/OCPBUGS-24638[*OCPBUGS-24638*])

      If we see in rdpmc-patch-master tuned:

      NAMESPACE                                NAME                                          TUNED                APPLIED   DEGRADED   AGE

openshift-cluster-node-tuning-operator   master2    rdpmc-patch-master   True      True       5d

      We are configuring below in rdpmc-patch-master tuned:

      $ oc get tuned rdpmc-patch-master -n openshift-cluster-node-tuning-operator -oyaml |less
spec:
  profile:
  - data: |
      [main]
      include=performance-patch-master
      [sysfs]
      /sys/devices/cpu/rdpmc = 2
    name: rdpmc-patch-master
  recommend:

      Below in Performance-patch-master which is included in above tuned:

      spec:
  profile:
  - data: |
      [main]
      summary=Custom tuned profile to adjust performance
      include=openshift-node-performance-master-profile
      [bootloader]
      cmdline_removeKernelArgs=-nohz_full=${isolated_cores}

      Below(which is coming in error) is in openshift-node-performance-master-profile included in above tuned:

      net.core.rps_default_mask=${not_isolated_cpumask}
