-	  DMA remapping (DMAR) devices support enables independent address

-	  Expose Intel IOMMU internals in Debugfs.

-config INTEL_IOMMU_DEFAULT_ON
-	def_bool y
-	prompt "Enable Intel DMA Remapping Devices by default"
-	depends on INTEL_IOMMU
-	help
-	  Selecting this option will enable a DMAR device at boot time if
-	  one is found. If this option is not selected, DMAR support can
-	  be enabled by passing intel_iommu=on to the kernel.

-config INTEL_IOMMU_BROKEN_GFX_WA
-	bool "Workaround broken graphics drivers (going away soon)"
-	depends on INTEL_IOMMU && BROKEN && X86
-	help
-	  Current Graphics drivers tend to use physical address
-	  for DMA and avoid using DMA APIs. Setting this config
-	  option permits the IOMMU driver to set a unity map for
-	  all the OS-visible memory. Hence the driver can continue
-	  to use physical addresses for DMA, at least until this
-	  option is removed in the 2.6.32 kernel.
-
-config INTEL_IOMMU_FLOPPY_WA
-	def_bool y
-	depends on INTEL_IOMMU && X86
-	help
-	  Floppy disk drivers are known to bypass DMA API calls
-	  thereby failing to work when IOMMU is enabled. This
-	  workaround will setup a 1:1 mapping for the first
-	  16MiB to make floppy (an ISA device) work.

-config INTEL_IOMMU_SCALABLE_MODE_DEFAULT_ON
-	bool "Enable Intel IOMMU scalable mode by default"
-	depends on INTEL_IOMMU
-	help
-	  Selecting this option will enable by default the scalable mode if
-	  hardware presents the capability. The scalable mode is defined in
-	  VT-d 3.0. The scalable mode capability could be checked by reading
-	  /sys/devices/virtual/iommu/dmar*/intel-iommu/ecap. If this option
-	  is not selected, scalable mode support could also be enabled by
-	  passing intel_iommu=sm_on to the kernel. If not sure, please use
-	  the default value.
