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.

• Immediate include surface: `linux/module.h`, `linux/platform_device.h`, `linux/delay.h`, `linux/types.h`, `linux/errno.h`, `linux/mm.h`, `linux/mman.h`, `linux/fb.h`.
• Detected declarations: `function s1d13xxxfb_readreg`, `function s1d13xxxfb_writereg`, `function s1d13xxxfb_runinit`, `function lcd_enable`, `function crt_enable`, `function s1d13xxxfb_setup_pseudocolour`, `function s1d13xxxfb_setup_truecolour`, `function s1d13xxxfb_set_par`, `function s1d13xxxfb_setcolreg`, `function s1d13xxxfb_blank`.
• Atlas domain: Driver Families / drivers/video.
• 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.
