| What: /sys/kernel/iommu_groups/ |
| Contact: Alex Williamson <alex.williamson@redhat.com> |
| 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. |
