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.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• 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.

• Immediate include surface: `linux/module.h`, `linux/netdevice.h`, `linux/ethtool.h`, `linux/mutex.h`, `linux/list.h`, `linux/rculist.h`, `linux/spinlock.h`, `linux/pci.h`.
• Detected declarations: `struct bnxt_re_dcb_work`, `function bnxt_re_set_db_offset`, `function bnxt_re_set_drv_mode`, `function bnxt_re_destroy_chip_ctx`, `function bnxt_re_setup_chip_ctx`, `function bnxt_re_get_sriov_func_type`, `function bnxt_re_limit_pf_res`, `function bnxt_re_limit_vf_res`, `function bnxt_re_set_resource_limits`, `function bnxt_re_vf_res_config`.
• Atlas domain: Driver Families / drivers/infiniband.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.
• IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
