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. +Users: |
