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.
