Classification: CPC G | IPC G

Claim 15:
16. A non-transitory computer-readable storage medium, storing a computer program that is executed by at least one processor, wherein upon execution by the at least one processor, the computer program is configured to cause the at least one processor to:
parse a received interrupt request to obtain a target Virtual Function (VF) port;
determine a target physical-side interrupt handler corresponding to the target VF port;
obtain target command information corresponding to the target physical-side interrupt handler in a device memory overlap region, wherein the device memory overlap region is an overlap region obtained by performing memory mapping on a Physical Function (PF) port and each VF port in a host address space by a device memory overlap mapping technology; and
switch to the target physical-side interrupt handler, and perform a response operation on the target command information;
wherein the computer program is configured to cause the at least one processor to:
obtain a target interrupt enabled status bit in a first memory overlap partition that is only read by a PF port and only written by a VF port in the device memory overlap region; and
determine the target VF port according to the target interrupt enabled status bit.
