====================
Compute Express Link
====================

CXL device configuration has a complex handoff between platform (Hardware,
BIOS, EFI), OS (early boot, core kernel, driver), and user policy decisions
that have impacts on each other.  The docs here break up configurations steps.

Annotation

Atlas domain: Support Tooling And Documentation / Documentation.
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.
