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.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

- Thermal support.

- Bifrost support:
  - DT bindings (Neil, WIP)
  - MMU page table format and address space setup
  - Bifrost specific feature and issue handling
  - Coherent DMA support

- Support userspace controlled GPU virtual addresses. Needed for Vulkan. (Tomeu)

- Compute job support. So called 'compute only' jobs need to be plumbed up to
  userspace.

- Support core dump on job failure

Annotation

• Atlas domain: Driver Families / drivers/gpu.
• Implementation status: atlas-only.

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.
