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/errno.h
• linux/types.h

Detected Declarations

• struct asus_hid_listener
• enum asus_ally_mcu_hack
• enum asus_hid_event
• function set_ally_mcu_hack
• function asus_wmi_get_devstate_dsts
• function asus_wmi_evaluate_method
• function asus_hid_register_listener
• function asus_hid_unregister_listener

Annotation

• Immediate include surface: `linux/errno.h`, `linux/types.h`.
• Detected declarations: `struct asus_hid_listener`, `enum asus_ally_mcu_hack`, `enum asus_hid_event`, `function set_ally_mcu_hack`, `function asus_wmi_get_devstate_dsts`, `function asus_wmi_evaluate_method`, `function asus_hid_register_listener`, `function asus_hid_unregister_listener`.
• 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.
