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/bitops.h`, `linux/delay.h`, `linux/module.h`, `linux/slab.h`, `linux/interrupt.h`, `linux/input.h`, `linux/serio.h`, `linux/init.h`.
• Detected declarations: `function psmouse_report_standard_buttons`, `function psmouse_report_standard_motion`, `function psmouse_report_standard_packet`, `function psmouse_process_byte`, `function __psmouse_set_state`, `function psmouse_set_state`, `function psmouse_handle_byte`, `function psmouse_handle_oob_data`, `function psmouse_pre_receive_byte`, `function psmouse_receive_byte`.
• Atlas domain: Driver Families / drivers/input.
• 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.
