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

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

Detected Declarations

• struct __raw_tickets

Annotated Snippet

struct __raw_tickets {
#ifdef __ARMEB__
			u16 next;
			u16 owner;
#else
			u16 owner;
			u16 next;
#endif
		} tickets;
	};
} arch_spinlock_t;

#define __ARCH_SPIN_LOCK_UNLOCKED	{ { 0 } }

typedef struct {
	u32 lock;
} arch_rwlock_t;

#define __ARCH_RW_LOCK_UNLOCKED		{ 0 }

#endif

Annotation

• Detected declarations: `struct __raw_tickets`.
• Atlas domain: Architecture Layer / arch/arm.
• 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.
