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
<T
> implementations.

zx_status_t GetSegmentMcfgAllocation (size_t segment, McfgAllocation * out)Search the MCFG allocations found earlier for an entry matching a given
segment a host bridge is a part of. Per the PCI Firmware spec v3 table 4-3
note 1, a given segment group will contain only a single mcfg allocation
entry.
