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
• i40e_adminq_cmd.h

Detected Declarations

• struct i40e_hw
• struct i40e_diag_reg_test_info
• enum i40e_lb_mode

Annotated Snippet

	u32 offset;	/* the base register */
	u32 mask;	/* bits that can be tested */
	u32 elements;	/* number of elements if array */
	u32 stride;	/* bytes between each element */
};

Annotation

• Immediate include surface: `linux/types.h`, `i40e_adminq_cmd.h`.
• Detected declarations: `struct i40e_hw`, `struct i40e_diag_reg_test_info`, `enum i40e_lb_mode`.
• Atlas domain: Driver Families / drivers/net.
• 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.
