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

• linux/jiffies.h
• linux/mutex.h
• linux/regmap.h
• linux/rtc.h

Detected Declarations

• struct mtk_rtc_data
• struct mt6397_rtc

Annotated Snippet

	u32                     wrtgr;

struct mt6397_rtc {
	struct rtc_device       *rtc_dev;

	/* Protect register access from multiple tasks */
	struct mutex            lock;
	struct regmap           *regmap;
	int                     irq;
	u32                     addr_base;
	const struct mtk_rtc_data *data;

Annotation

• Immediate include surface: `linux/jiffies.h`, `linux/mutex.h`, `linux/regmap.h`, `linux/rtc.h`.
• Detected declarations: `struct mtk_rtc_data`, `struct mt6397_rtc`.
• 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.
