- DMA remapping (DMAR) devices support enables independent address
- translations for Direct Memory Access (DMA) from devices.
- These DMA remapping devices are reported via ACPI tables
- and include PCI device scope covered by these DMA
- remapping devices.

- DO NOT ENABLE THIS OPTION UNLESS YOU REALLY KNOW WHAT YOU ARE DOING!!!
-
- Expose Intel IOMMU internals in Debugfs.
-
- This option is -NOT- intended for production environments, and should
- only be enabled for debugging Intel IOMMU.

- Shared Virtual Memory (SVM) provides a facility for devices
- to access DMA resources through process address space by
- means of a Process Address Space ID (PASID).

- 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.
