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 ;-)
