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.

• 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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h

Detected Declarations

• struct host_queue_header

Annotated Snippet

struct host_queue_header {
	__u64 read_index;
	struct {
		__u16 major;
		__u16 minor;
	} version;
	__u32 capacity; /* Queue capacity, must be power of two. */
	__u64 write_index;
	__u64 data_address; /* The xdna dev addr for payload. */
};

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct host_queue_header`.
• Atlas domain: Driver Families / drivers/accel.
• 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.
