Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

• Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `cxgbit.h`, `net/dcbevent.h`, `cxgb4_dcb.h`.
• Detected declarations: `struct cxgbit_dcb_work`, `function _cxgbit_free_cdev`, `function cxgbit_set_mdsl`, `function cxgbit_close_conn`, `function cxgbit_detach_cdev`, `function cxgbit_uld_state_change`, `function cxgbit_process_ddpvld`, `function cxgbit_lro_add_packet_rsp`, `function cxgbit_copy_frags`, `function cxgbit_lro_add_packet_gl`.
• Atlas domain: Driver Families / drivers/target.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
