In linux kernel since version 3.10 (release Date: 2013-06-30)  
Process Address Space Identifiers (PASIDs) can be used by PCI devices
to access more than one IO address space at the same time. To make
use of this feature an IOMMU is required which also supports PASIDs.
Select this option if you have such an IOMMU and want to compile the
driver for it into your kernel.

If unsure, say N.
