Abstract
Mechanisms are provided for implementing a multi-root PCI manager (MR-PCIM) in a multi-root I/O virtualization management partition (MR-IMP) to control the shared functionality of an multi-root I/O virtualization (IOV) enabled switch fabric and multi-root IOV enabled I/O adapter (IOA) through the base functions (BF) of the switches and IOAs. A hypervisor provides device-independent facilities to the code running in the I/O Virtualization Management Partition (IMP), Multi-Root (MR)-IMP and client partitions. The MR-IMP may include device specific code without the hypervisor needing to sacrifice its size, robustness, and upgradeability. The hypervisor provides the virtual intermediary functionally for the sharing and control of the switch and IOA's control functions.
