Annotated Snippet

What:		/sys/class/iommu/<iommu>/intel-iommu/address
Date:		June 2014
KernelVersion:	3.17
Contact:	Alex Williamson <alex.williamson@redhat.com>
Description:
		Physical address of the VT-d DRHD for this IOMMU.

Implementation status: atlas-only.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
