Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

# N.B. The below cannot be expressed with a single line using
# CONFIG_XEN_PCI_STUB as it always remains in "y" state,
# thus preventing the driver to be built as a module.
# Please note, that CONFIG_XEN_PCIDEV_BACKEND and
# CONFIG_XEN_PCIDEV_STUB are mutually exclusive.

Annotation

• Atlas domain: Driver Families / drivers/xen.
• 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.
