Detailed Description
Base class implementing the PCI bridge interface.Defines everything needed to handle several PCI devices (or to act as a container of PCI devices).
Member Function Documentation
| virtual int pci_bridge_base::register_device | ( | pci_device * | device | ) | [inline, virtual] |
Registers the PCI device at this bridge.
Registered devices are automatically freed when the bridge is destroyed.
Implements pci_bridge.
References device_container< DeviceT >::register_device().
| virtual const search_result pci_bridge_base::search_ioregion | ( | enum pci_ioregion::type | type, | |
| l4_gpa_t | base, | |||
| l4_gpa_t | size = 1 | |||
| ) | const [inline, virtual] |
Searchs an I/O region and returns it in a search_result struct.
base & size are I/O space addresses (ports) or guest physical addresses depending on the type to search for.
Implements pci_bridge.
