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/pci.h
• linux/netdevice.h
• linux/types.h
• linux/workqueue.h

Detected Declarations

• struct qedr_dev
• struct qed_dev
• struct qede_dev
• struct qede_rdma_event_work
• struct qedr_driver
• enum qede_rdma_event
• function qede_rdma_dev_add
• function qede_rdma_dev_event_open

Annotation

• Immediate include surface: `linux/pci.h`, `linux/netdevice.h`, `linux/types.h`, `linux/workqueue.h`.
• Detected declarations: `struct qedr_dev`, `struct qed_dev`, `struct qede_dev`, `struct qede_rdma_event_work`, `struct qedr_driver`, `enum qede_rdma_event`, `function qede_rdma_dev_add`, `function qede_rdma_dev_event_open`.
• 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.
