========================================
SLIT - System Locality Information Table
========================================

The system locality information table provides "abstract distances" between
accessor and memory nodes.  Node without initiators (cpus) are infinitely (FF)
distance away from all other nodes.

The abstract distance described in this table does not describe any real
latency of bandwidth information.

Example ::

    Signature : "SLIT"    [System Locality Information Table]
   Localities : 0000000000000004
 Locality   0 : 10 20 20 30
 Locality   1 : 20 10 30 20
 Locality   2 : FF FF 0A FF
 Locality   3 : FF FF FF 0A

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.
