Handling interrupts from a virtual function in a system with a Multi-Die reconfigurable processor

A method of operating a system that comprises a communication link, a runtime processor that is operatively coupled to the communication link, and a reconfigurable processor comprising a package, first and second dies that are arranged in the package, wherein the first die comprises first arrays of coarse-grained reconfigurable units and a first communication link interface that couples the first die to the runtime processor via the communication link, and wherein the second die comprises second arrays of coarse-grained reconfigurable units and a second communication link interface that couples the second die to the runtime processor via the communication link, the method comprising:

• configuring, with the runtime processor, the first and second communication link interfaces to provide access to the first and second arrays of coarse-grained reconfigurable units from first and second physical function drivers and from at least one virtual function driver;
• generating, with the reconfigurable processor, an interrupt in response to a predetermined event;
• and
• routing, with the reconfigurable processor, the interrupt to one of the first physical function driver or the second physical function driver and to a virtual function driver of the at least one virtual function driver.

A non-transitory computer-readable storage medium including instructions that, when executed by a processing unit, cause the processing unit to operate a system that comprises a communication link, a runtime processor that is operatively coupled to the communication link, and a reconfigurable processor comprising a package, first and second dies that are arranged in the package, wherein the first die comprises first arrays of coarse-grained reconfigurable units and a first communication link interface that couples the first die to the runtime processor via the communication link, and wherein the second die comprises second arrays of coarse-grained reconfigurable units and a second communication link interface that couples the second die to the runtime processor via the communication link, the instructions comprising:

• configuring the first and second communication link interfaces to provide access to the first and second arrays of coarse-grained reconfigurable units from first and second physical function drivers and from at least one virtual function driver;
• generating an interrupt in response to a predetermined event;
• and
• routing the interrupt to one of the first physical function driver or the second physical function driver and to a virtual function driver of the at least one virtual function driver.
