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/types.h

Detected Declarations

• struct device
• struct irq_domain
• struct gpio_chip

Annotated Snippet

#ifndef GPIO_REG_H
#define GPIO_REG_H

#include <linux/types.h>

struct device;
struct irq_domain;

struct gpio_chip;

struct gpio_chip *gpio_reg_init(struct device *dev, void __iomem *reg,
	int base, int num, const char *label, u32 direction, u32 def_out,
	const char *const *names, struct irq_domain *irqdom, const int *irqs);

int gpio_reg_resume(struct gpio_chip *gc);

#endif /* GPIO_REG_H */

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct device`, `struct irq_domain`, `struct gpio_chip`.
• 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.
