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

# SPDX-License-Identifier: GPL-2.0

# Order is important here for the built-in case:
# - 'core' first for fundamental init
# - 'port' before platform root drivers like 'acpi' so that CXL-root ports
#   are immediately enabled
# - 'mem' and 'pmem' before endpoint drivers so that memdevs are
#   immediately enabled
# - 'pci' last, also mirrors the hardware enumeration hierarchy

Annotation

• Atlas domain: Driver Families / drivers/cxl.
• 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.
