    FWIW:
    I'm posting this since it took me more than one webpage to learn by myself :)

    Way of checking PPIN of an Intel CPU (some Xeons):
    1. Enable this feature in BIOS
    2. Instal msr-tools (at least this is the package name on arch linux)
    3. Run the code (omitting sudo stuff for simplicity)
      Code:
      # rdmsr 0x4f
    4. Check output ;-)
    5. Disable the feature in BIOS ;-)
