Abstract
Described herein are enhancements for managing multi-host Peripheral Component Interconnect Express (PCIe) switching. In one implementation, a system includes one or more PCIe devices and a PCIe switch configured to receive a first interrupt corresponding to a first interrupt vector from a PCIe device, wherein the first interrupt vector comprises at least a virtual address and a first data value. The switch is further configured to translate the first interrupt vector into a second interrupt vector, wherein the second interrupt vector comprises a second address and a second data value, and transfer a second interrupt using the second interrupt vector to a host of a plurality of hosts that corresponds to the second interrupt vector.
