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 or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `drm/amd_asic_type.h`, `drm/drm_print.h`.
• Detected declarations: `struct amdgpu_ip_block`, `struct amd_ip_funcs`, `enum amd_chip_flags`, `enum amd_apu_flags`, `enum amd_ip_block_type`, `enum amd_clockgating_state`, `enum amd_powergating_state`, `enum PP_FEATURE_MASK`, `enum amd_harvest_ip_mask`, `enum DC_FEATURE_MASK`.
• Atlas domain: Driver Families / drivers/gpu.
• 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.
