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.

Annotation
- Immediate include surface: `fifo_monitor_public.h`, `gp_device.h`, `device_access.h`, `assert_support.h`.
- Detected declarations: `function fifo_switch_set`, `function fifo_switch_get`, `function fifo_monitor_reg_store`, `function fifo_monitor_reg_load`.
- Atlas domain: Driver Families / drivers/staging.
- 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.
