12 Linux has a comprehensive PCI subsystem to support PCI controllers that
13 operates in Root Complex mode. The subsystem has capability to scan PCI bus,
15 vendor ID, device ID), support other services like hot-plug, power management,
19 either in Root Complex mode or Endpoint mode. PCI Endpoint Framework will
20 add endpoint mode support in Linux. This will help to run Linux in an
22 validation, co-processor accelerator, etc.
