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

	help
	  Say Y here to include support for Intel "High Definition
	  Audio" (Azalia) and its compatible devices.

	  This option enables the HD-audio controller.  Don't forget
	  to choose the appropriate HD-audio codec options.

	  To compile this driver as a module, choose M here: the module
	  will be called snd-hda-intel.

	help
	  Say Y here to support the HDA controller present in NVIDIA
	  Tegra SoCs

	  This options enables support for the HD Audio controller
	  present in some NVIDIA Tegra SoCs, used to communicate audio
	  to the HDMI output.

	  To compile this driver as a module, choose M here: the module
	  will be called snd-hda-tegra.

	  present in some CIX SoCs.

	  To compile this driver as a module, choose M here: the module
	  will be called snd-hda-cix-ipbloq.

config SND_HDA_ACPI
	tristate "HD Audio ACPI"
	depends on ACPI
	select SND_HDA
	help
	  Say Y here to include support for Azalia-compatible HDA controllers
	  which are advertised via ACPI objects.

Atlas domain: Driver Families / sound/hda.
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.
