| 5 | Description: /sys/kernel/iommu_groups/ contains a number of sub- |
| 6 | directories, each representing an IOMMU group. The |
| 7 | name of the sub-directory matches the iommu_group_id() |
| 8 | for the group, which is an integer value. Within each |
| 9 | subdirectory is another directory named "devices" with |
| 10 | links to the sysfs devices contained in this group. |
| 11 | The group directory also optionally contains a "name" |
| 12 | file if the IOMMU driver has chosen to register a more |
| 13 | common name for the group. |
