+Description: /sys/kernel/iommu_groups/ contains a number of sub-
+ directories, each representing an IOMMU group. The
+ name of the sub-directory matches the iommu_group_id()
+ for the group, which is an integer value. Within each
+ subdirectory is another directory named "devices" with
+ links to the sysfs devices contained in this group.
+ The group directory also optionally contains a "name"
+ file if the IOMMU driver has chosen to register a more
+ common name for the group.
