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/firmware/imx/ipc.h
• linux/firmware/imx/svc/misc.h
• linux/firmware/imx/svc/pm.h
• linux/firmware/imx/svc/rm.h

Detected Declarations

• function imx_scu_soc_init
• function imx_scu_enable_general_irq_channel
• function imx_scu_irq_register_notifier
• function imx_scu_irq_unregister_notifier
• function imx_scu_irq_group_enable
• function imx_scu_irq_get_status

Annotation

• Immediate include surface: `linux/firmware/imx/ipc.h`, `linux/firmware/imx/svc/misc.h`, `linux/firmware/imx/svc/pm.h`, `linux/firmware/imx/svc/rm.h`.
• Detected declarations: `function imx_scu_soc_init`, `function imx_scu_enable_general_irq_channel`, `function imx_scu_irq_register_notifier`, `function imx_scu_irq_unregister_notifier`, `function imx_scu_irq_group_enable`, `function imx_scu_irq_get_status`.
• 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.
