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.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/bitops.h
• linux/module.h
• crypto/aes.h
• tegra-se.h

Detected Declarations

• function tegra_keyslot_alloc
• function tegra_keyslot_free
• function tegra_key_prep_ins_cmd
• function tegra_key_in_kslt
• function tegra_key_insert
• function tegra_key_invalidate
• function tegra_key_invalidate_reserved
• function tegra_key_submit_reserved
• function tegra_key_submit

Annotated Snippet

			dev_dbg(se->dev, "failed to allocate key slot\n");
			return -ENOMEM;
		}
	}

	ret = tegra_key_insert(se, key, keylen, *keyid, alg);
	if (ret)
		return ret;

	return 0;

Annotation

• Immediate include surface: `linux/bitops.h`, `linux/module.h`, `crypto/aes.h`, `tegra-se.h`.
• Detected declarations: `function tegra_keyslot_alloc`, `function tegra_keyslot_free`, `function tegra_key_prep_ins_cmd`, `function tegra_key_in_kslt`, `function tegra_key_insert`, `function tegra_key_invalidate`, `function tegra_key_invalidate_reserved`, `function tegra_key_submit_reserved`, `function tegra_key_submit`.
• Atlas domain: Driver Families / drivers/crypto.
• Implementation status: source 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.
