Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

• CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h

Detected Declarations

• struct idprom

Annotated Snippet

struct idprom {
	u8		id_format;	/* Format identifier (always 0x01) */
	u8		id_machtype;	/* Machine type */
	u8		id_ethaddr[6];	/* Hardware ethernet address */
	s32		id_date;	/* Date of manufacture */
	u32		id_sernum:24;	/* Unique serial number */
	u8		id_cksum;	/* Checksum - xor of the data bytes */
	u8		reserved[16];
};

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct idprom`.
• Atlas domain: Architecture Layer / arch/m68k.
• 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.
