Key:

Chip	the chip, or chip family, associated with this row of data
Driver	Linux driver(s)
NCQ	Supports FPDMA
DMA++	DMA engine is more advanced than standard PCI IDE BMDMA engine.
hotplug	Supports interrupt-driven device hotplug and hot unplug. Note that hotplug can often be "hacked" via polling, even if hardware does not natively support it.
PMP	Supports SATA port multipliers. "FIS" is FIS-based context switching, the greatly preferred technology. "cmd" is command-based context switching, much slower. "no" means no support at all.
