Physical-to-logical bus mapping scheme for computer systems having multiple PCI bus configuration |
摘要 |
A Plug-and-Play (PnP) configuration driver initilization routine and PnP configuration utility for use in PCI bus architectures supporting dynamic I/O bus configurations. The PnP configuration driver includes a logical-to-physical PCI bus mapping scheme maintaining a PCI bus mapping table, and creating a logical-to-physical map table at start-of-day. PCI device drivers access devices through the logical bus numbers, thereby avoiding errors resulting when physical bus numbers change as a result of the addition or removal of buses within a computer system supporting dynamic I/O bus configurations.
