class PciRootHost

Defined at line 41 of file ../../src/devices/pci/lib/pci/include/lib/pci/root_host.h

PciRootHost holds references to any platform information on a PCI Root basis, as well as their

protocols. Allocators are shared across PCi Bus Drivers. It provides a common interface that can

be implemented on a given platform and paired with Pciroot

> implementations.
