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.

# Unicode table for IBM Codepage 437. Note that there are many more
# substitutions that could be conceived (for example, thick-line
# graphs probably should be replaced with double-line ones, accented
# Latin characters should replaced with their nonaccented versions,
# and some upper case Greek characters could be replaced by Latin), however,
# I have limited myself to the Unicodes used by the kernel ISO 8859-1,
# DEC VT, and IBM CP 437 tables.

- Atlas domain: Driver Families / drivers/tty.
- 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.
