[PCM] pcm-pcie utility

      Would you please document what pcm-pcie is actually reporting? I'd like to understand how DDIO is impacting my system.



pcm-pcie outputs help on the counted metrics if run without parameters. It counts PCIE transfer events and outputs them, optionally with a bandwidth estimation per socket (-B flag). Non-zero PCIeItoM event counts indicate DDIO is active.
