Why This File Exists

Networking stack implementation surface: socket APIs, protocol dispatch, packet flow, routing, filtering, and network namespaces.

• Networking stack implementation surface: socket APIs, protocol dispatch, packet flow, routing, filtering, and network namespaces.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

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

Detected Declarations

• struct shm_channel

Annotated Snippet

struct shm_channel {
	struct device *dev;
	void __iomem *base;
};

void mana_smc_init(struct shm_channel *sc, struct device *dev,
		   void __iomem *base);

int mana_smc_setup_hwc(struct shm_channel *sc, bool reset_vf, u64 eq_addr,
		       u64 cq_addr, u64 rq_addr, u64 sq_addr,
		       u32 eq_msix_index);

int mana_smc_teardown_hwc(struct shm_channel *sc, bool reset_vf);

Annotation

• Detected declarations: `struct shm_channel`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• Implementation status: source implementation candidate.
• IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
