Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/acpi.h
• linux/fwnode.h
• linux/irqdomain.h

Detected Declarations

• function iort_msi_map_id
• function iort_msi_xlate
• function iort_its_translate_pa
• function iort_pmsi_get_msi_info
• function acpi_configure_pmsi_domain
• function iort_iommu_configure_id
• function iort_iommu_get_resv_regions

Annotation

• Immediate include surface: `linux/acpi.h`, `linux/fwnode.h`, `linux/irqdomain.h`.
• Detected declarations: `function iort_msi_map_id`, `function iort_msi_xlate`, `function iort_its_translate_pa`, `function iort_pmsi_get_msi_info`, `function acpi_configure_pmsi_domain`, `function iort_iommu_configure_id`, `function iort_iommu_get_resv_regions`.
• Atlas domain: Core OS / Core Kernel Interface.
• Implementation status: source implementation candidate.

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.
