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