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

• common.h

Detected Declarations

• struct davinci_id

Annotated Snippet

struct davinci_id {
	u8	variant;	/* JTAG ID bits 31:28 */
	u16	part_no;	/* JTAG ID bits 27:12 */
	u16	manufacturer;	/* JTAG ID bits 11:1 */
	u32	cpu_id;
	char	*name;
};

/* Can use lower 16 bits of cpu id  for a variant when required */
#define	DAVINCI_CPU_ID_DA850		0x08500000

Annotation

• Immediate include surface: `common.h`.
• Detected declarations: `struct davinci_id`.
• 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.
