Hi Rahul,

Add cmdline boot option "pci=on" to enable/disable the PCI init during
boot.

I read this as "PCI" will be either disabled/enabled for the platform.Whereas, I think it will be used to decide whether Xen discover PCI andPCI passthrough is supported or not.


Can you also clarify why a user would want to select "pci=off"?

Cheers,
