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 apds990x_chip_factors
• struct apds990x_platform_data

/**
 * struct apds990x_platform_data - platform data for apsd990x.c driver

 * @ppcount: number of IR pulses used for proximity estimation
 * @setup_resources: interrupt line setup call back function
 * @release_resources: interrupt line release call back function

 * Proximity detection result depends heavily on correct ppcount, pdrive
 * and cover window.

Annotation

• Detected declarations: `struct apds990x_chip_factors`, `struct apds990x_platform_data`.
• 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.
