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

• uapi/asm/bootinfo.h
• uapi/asm/setup.h

Detected Declarations

• struct m68k_mem_info

Annotated Snippet

struct m68k_mem_info {
	unsigned long addr;		/* physical address of memory chunk */
	unsigned long size;		/* length of memory chunk (in bytes) */
};

extern int m68k_num_memory;		/* # of memory blocks found (and used) */
extern int m68k_realnum_memory;		/* real # of memory blocks found */
extern struct m68k_mem_info m68k_memory[NUM_MEMINFO];/* memory description */
#endif

#endif /* _M68K_SETUP_H */

Annotation

• Immediate include surface: `uapi/asm/bootinfo.h`, `uapi/asm/setup.h`.
• Detected declarations: `struct m68k_mem_info`.
• 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.
