145 subsystems

Top-level groups under drivers/. Counts cover all 2,028 leaf directories in the corpus (across the 145 subsystems below) — 2,028 probed dossiers + 0 Phase 1 stubs. Click into any subsystem to see its register; mega-subsystems (drm/amd, iwlwifi, nvme, intel/mellanox/broadcom net, staging, …) are present here as stub-only listings — see methodology.

Counts: 2,028 directories = 2,028 dossiers + 0 stubs. Cell number is total in that subsystem; the split shows dossier/stub when both are present.
