摘要：
A PCI control manager provides address translation protection tables in switches in a PCI fabric. The PCI control manager discovers the fabric and provides a virtual tree for each root complex. A system administrator may then remove endpoints that do not communicate with the root complex to configure the PCI fabric. The PCI control manager then provides updated ATPT tables to the switches. When a host or adapter is added, the master PCM goes through the discovery process and the ATPT tables and adapter routing tables are modified to reflect the change in configuration. The master PCM can query the ATPT tables and adapter routing tables to determine what is in the configuration. The master PCM can also destroy entries in the ATPT tables and adapter routing tables when a device is removed from the configuration and those entries are no longer valid.
