config IUCV
	depends on S390
	def_tristate y if S390
	prompt "IUCV support (S390 - z/VM only)"
	help
	  Select this option if you want to use inter-user communication
	  under VM or VIF. If you run on z/VM, say "Y" to enable a fast
	  communication link between VM guests.

config AFIUCV
	depends on S390
	def_tristate m if QETH_L3 || IUCV
	prompt "AF_IUCV Socket support (S390 - z/VM and HiperSockets transport)"
	help
	  Select this option if you want to use AF_IUCV socket applications
	  based on z/VM inter-user communication vehicle or based on
	  HiperSockets.

Annotation

• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• 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.
