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.

	  Host System Management Port (HSMP) interface is a mailbox interface
	  between the x86 core and the System Management Unit (SMU) firmware.
	  The driver provides a way for user space tools to monitor and manage
	  system management functionality on EPYC and MI300A server CPUs
	  from AMD.

	  This option supports ACPI based probing.
	  You may enable this, if your platform BIOS provides an ACPI object
	  as described in amd_hsmp.rst document.

	  If you choose to compile this driver as a module the module will be
	  called hsmp_acpi.

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.
