MSIX interrupt processing method and device, equipment and medium

The invention discloses an MSIX interrupt processing method and device, equipment and a medium, relates to the technical field of computers, is applied to a host of PCIe equipment, and comprises the steps that a request sent by a current virtual driver and used for applying for initial MSIX interrupt resources is received; wherein the number of the initial MSIX interrupt resources corresponds to the maximum interrupt number in the PCIe configuration space of the current virtual driver; recording a mapping relation between the initial MSIX interrupt resource and a global index in an interrupt vector mapping table, and establishing a mapping relation between a memory base address of the interrupt vector mapping table and a virtual function ID; and if the current virtual driver applies for the target interrupt resource from the kernel of the operating system, the hardware determines the virtual function ID and the address offset so as to obtain the target global index, and interrupt read-write operation is perfo
