Detailed Description
Interface for PCI bridges.Defines everything a machine (or annother bridge) needs to know about its (inner) bridge.
Member Function Documentation
| virtual int pci_bridge::register_device | ( | pci_device * | device | ) | [pure virtual] |
Registers the PCI device at this bridge.
Registered devices are automatically freed when the bridge is destroyed.
Implemented in pci_bridge_base.
| virtual const search_result pci_bridge::search_ioregion | ( | enum pci_ioregion::type | type, | |
| l4_gpa_t | base, | |||
| l4_gpa_t | size = 1 | |||
| ) | const [pure 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.
Implemented in pci_bridge_base.
