Annotation
- Immediate include surface: `linux/types.h`.
- Detected declarations: `struct hdsp_peak_rms`, `struct hdsp_config_info`, `struct hdsp_firmware`, `struct hdsp_version`, `struct hdsp_mixer`, `struct hdsp_9632_aeb`, `enum HDSP_IO_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.
