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/types.h
• linux/virtio_ids.h
• linux/virtio_config.h

Detected Declarations

• struct virtio_pmem_config
• struct virtio_pmem_resp
• struct virtio_pmem_req

Annotated Snippet

struct virtio_pmem_config {
	__le64 start;
	__le64 size;
};

#define VIRTIO_PMEM_REQ_TYPE_FLUSH      0

struct virtio_pmem_resp {
	/* Host return status corresponding to flush request */
	__le32 ret;
};

struct virtio_pmem_req {
	/* command type */
	__le32 type;
};

Annotation

• Immediate include surface: `linux/types.h`, `linux/virtio_ids.h`, `linux/virtio_config.h`.
• Detected declarations: `struct virtio_pmem_config`, `struct virtio_pmem_resp`, `struct virtio_pmem_req`.
• 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.
