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 an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/device.h
• linux/irq.h
• linux/irqdomain.h
• linux/mutex.h

Detected Declarations

• struct moxtet
• struct moxtet_irqpos
• struct moxtet_driver
• struct moxtet_device
• enum turris_mox_cpu_module_id
• enum turris_mox_module_id
• function moxtet_unregister_driver
• function to_moxtet_device

Annotation

• Immediate include surface: `linux/device.h`, `linux/irq.h`, `linux/irqdomain.h`, `linux/mutex.h`.
• Detected declarations: `struct moxtet`, `struct moxtet_irqpos`, `struct moxtet_driver`, `struct moxtet_device`, `enum turris_mox_cpu_module_id`, `enum turris_mox_module_id`, `function moxtet_unregister_driver`, `function to_moxtet_device`.
• Atlas domain: Core OS / Core Kernel Interface.
• Implementation status: pattern 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.
