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

• asm/errno.h
• linux/uuid.h
• linux/cper.h
• asm/smp_plat.h

Detected Declarations

• struct atl_err
• function ras_userspace_consumers
• function ras_debugfs_init
• function log_non_standard_event
• function log_arm_hw_error
• function amd_retire_dram_row

Annotation

• Immediate include surface: `asm/errno.h`, `linux/uuid.h`, `linux/cper.h`, `asm/smp_plat.h`.
• Detected declarations: `struct atl_err`, `function ras_userspace_consumers`, `function ras_debugfs_init`, `function log_non_standard_event`, `function log_arm_hw_error`, `function amd_retire_dram_row`.
• 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.
