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

Claim 14:
15. A command information transmission apparatus, comprising:
a memory, configured to store a computer program; and
at least one processor, configured to execute the computer program 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 at least one processor is configured to execute the computer program 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.
