+         On some platforms where no separate I/O space exists, there are I/O
+         hosts which can not be accessed in MMIO mode. Using the logical PIO
+         mechanism, the host-local I/O resource can be mapped into system
+         logic PIO space shared with MMIO hosts, such as PCI/PCIe, then the
+         system can access the I/O devices with the mapped-logic PIO through
+         I/O accessors.
+
+         This way has relatively little I/O performance cost. Please make
+         sure your devices really need this configure item enabled.
+
+         When in doubt, say N.
