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

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

Detected Declarations

• struct si4713_platform_data
• struct si4713_rnl

Annotated Snippet

struct si4713_platform_data {
	bool is_platform_device;
};

/*
 * Structure to query for Received Noise Level (RNL).
 */
struct si4713_rnl {
	__u32 index;		/* modulator index */
	__u32 frequency;	/* frequency to perform rnl measurement */
	__s32 rnl;		/* result of measurement in dBuV */
	__u32 reserved[4];	/* drivers and apps must init this to 0 */
};

/*
 * This is the ioctl number to query for rnl. Users must pass a
 * struct si4713_rnl pointer specifying desired frequency in 'frequency' field
 * following driver capabilities (i.e V4L2_TUNER_CAP_LOW).
 * Driver must return measured value in the same structure, filling 'rnl' field.

Annotation

• Detected declarations: `struct si4713_platform_data`, `struct si4713_rnl`.
• 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.
