Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A command information transmission method, wherein the method is applied to a Physical Function (PF) port and comprises:
parsing a received interrupt request to obtain a target Virtual Function (VF) port;
determining a target physical-side interrupt handler corresponding to the target VF port;
obtaining 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 the PF port and each VF port in a host address space by a device memory overlap mapping technology; and
switching to the target physical-side interrupt handler, and performing a response operation on the target command information;
wherein the parsing a received interrupt request to obtain a target VF port comprises:
obtaining 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
determining the target VF port according to the target interrupt enabled status bit.
