        Hello,

         

        I am trying to implement PCIe pause in our kExt and cannot see a way to test this feature.  I found some documentation on apple.com saying that I need to do:

         

        sudo nvram boot-args="pci=0x200"

         

        Having done this, I still don't see any power state transitions when a new device is attached.  Any clues?

         

        Thank you,
