Why This File Exists

Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.

• Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h

Detected Declarations

• struct snd_sof_blk_hdr
• struct snd_sof_mod_hdr
• struct snd_sof_fw_header
• enum snd_sof_fw_blk_type
• enum snd_sof_fw_mod_type

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct snd_sof_blk_hdr`, `struct snd_sof_mod_hdr`, `struct snd_sof_fw_header`, `enum snd_sof_fw_blk_type`, `enum snd_sof_fw_mod_type`.
• Atlas domain: Repository Root And Misc / include.
• 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.
