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 iqs62x_event_data
• struct iqs62x_event_desc
• struct iqs62x_dev_desc
• struct iqs62x_core
• enum iqs62x_ui_sel
• enum iqs62x_event_reg
• enum iqs62x_event_flag

Annotation

• Detected declarations: `struct iqs62x_event_data`, `struct iqs62x_event_desc`, `struct iqs62x_dev_desc`, `struct iqs62x_core`, `enum iqs62x_ui_sel`, `enum iqs62x_event_reg`, `enum iqs62x_event_flag`.
• 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.
