Annotation
- Immediate include surface: `linux/types.h`, `uapi/linux/rpmsg_types.h`.
- Detected declarations: `function rpmsg_is_little_endian`, `function __rpmsg16_to_cpu`, `function __cpu_to_rpmsg16`, `function __rpmsg32_to_cpu`, `function __cpu_to_rpmsg32`, `function __rpmsg64_to_cpu`, `function __cpu_to_rpmsg64`.
- 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.
