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.

	  Select this option to enable the AMD Heterogeneous Core Hardware
	  Feedback Interface. If selected, hardware provides runtime thread
	  classification guidance to the operating system on the performance and
	  energy efficiency capabilities of each heterogeneous CPU core. These
	  capabilities may vary due to the inherent differences in the core types
	  and can also change as a result of variations in the operating
	  conditions of the system such as power and thermal limits.

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.
