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

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

Detected Declarations

• struct device
• struct dsa_chip_data

Annotated Snippet

struct dsa_chip_data {
	/*
	 * Reference to network devices
	 */
	struct device	*netdev[DSA_MAX_PORTS];

	/* set to size of eeprom if supported by the switch */
	int		eeprom_len;

	/*
	 * The names of the switch's ports.  Use "cpu" to
	 * designate the switch port that the cpu is connected to,
	 * "dsa" to indicate that this port is a DSA link to
	 * another switch, NULL to indicate the port is unused,
	 * or any other string to indicate this is a physical port.
	 */
	char		*port_names[DSA_MAX_PORTS];

Annotation

• Detected declarations: `struct device`, `struct dsa_chip_data`.
• 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.
