		The PTI (Parallel Trace Interface) driver directs
		trace data routed from various parts in the system out
		through an Intel Penwell PTI port and out of the mobile
		device for analysis with a debugging tool (Lauterbach or Fido).

		You should select this driver if the target kernel is meant for
		an Intel Atom (non-netbook) mobile device containing a MIPI
		P1149.7 standard implementation.
