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.

• 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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/kernel_stat.h`, `linux/completion.h`, `linux/workqueue.h`, `linux/spinlock.h`, `linux/device.h`, `linux/export.h`, `linux/module.h`, `linux/timer.h`.
• Detected declarations: `function EADM_LOG_HEX`, `function orb_init`, `function eadm_subchannel_start`, `function eadm_subchannel_clear`, `function eadm_subchannel_timeout`, `function eadm_subchannel_set_timeout`, `function eadm_subchannel_irq`, `function eadm_start_aob`, `function eadm_subchannel_probe`, `function eadm_quiesce`.
• Atlas domain: Driver Families / drivers/s390.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
