Multi-host peripheral component interconnect express (PCIe) switching based on interrupt vector from PCIe device

A system comprising:

• one or more Peripheral Component Interconnect Express (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;
• 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.

An apparatus comprising:

• means for receiving 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;
• means for translating the first interrupt vector into a second interrupt vector, wherein the second interrupt vector comprises a second address and a second data value;
• and
• means for transferring a second interrupt using the second interrupt vector to a host of a plurality of hosts that corresponds to the second interrupt vector.
