The performance profile creator seems like it is not supported for clusters that are on ARM architectures 

Always    

1. Label one of the nodes with worker-cnf

2. run oc adm must-gather on the cluster

3. Trying to run the podman command to generate the performance profile file with the must-gather directory

# podman run --entrypoint performance-profile-creator -v /root/mg:/mg:z registry-proxy.engineering.redhat.com/rh-osbs/openshift-ose-cluster-node-tuning-rhel9-operator@sha256:4bfa740bdc3b923e84d9c7ade981d0b54ae4b341b766d9249595ff41bcf7fe6d --must-gather-dir-path /mg --rt-kernel=false --mcp-name worker-cnf --reserved-cpu-count=4 --topology-manager-policy=single-numa-node --power-consumption-mode ultra-low-latency --user-level-networking
