If you set hugepages without setting defaultHugepagesSize, the template creates a broken template

    1. Apply the following PerformanceProfile spec:
  spec:
    additionalKernelArgs:
    - rcupdate.rcu_normal_after_boot=0
    - efi=runtime
    - vfio_pci.enable_sriov=1
    - vfio_pci.disable_idle_d3=1
    - module_blacklist=irdma
    hugepages:
      pages:
      - count: 32
        size: 1G

    2. Check the system after reboot, looking for the additionalKernelArgs
    3. 
    

    The additional args should be in /proc/cmdline

    They are not.

Root cause looks to be the PerformanceProfile template which assumes that if you set any hugepages you would have also set defaultHugepagesSize, and if not it produces a profile which confuses the tuned engine.
