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.
• Defines an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• 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.

Annotation

• Immediate include surface: `otx2_cpt_common.h`, `otx2_cptvf.h`, `otx2_cptlf.h`, `otx2_cptvf_algs.h`, `cn10k_cpt.h`, `rvu_reg.h`.
• Detected declarations: `function cptvf_enable_pfvf_mbox_intrs`, `function cptvf_disable_pfvf_mbox_intrs`, `function cptvf_register_interrupts`, `function cptvf_pfvf_mbox_init`, `function cptvf_pfvf_mbox_destroy`, `function cptlf_work_handler`, `function cleanup_tasklet_work`, `function init_tasklet_work`, `function free_pending_queues`, `function alloc_pending_queues`.
• Atlas domain: Driver Families / drivers/crypto.
• Implementation status: pattern 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.
