Selecting this option will enable a DMAR device at boot time if

one is found. If this option is not selected, DMAR support can

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

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.

Selecting this option will enable the performance monitoring

infrastructure in the Intel IOMMU. It collects information about

key events occurring during operation of the remapping hardware,

processors which support Intel VT-d 4.0 and later.
