STARTUP CONTROL METHOD, APPARATUS AND DEVICE FOR PCI DEVICES IN ARM SERVER

This present disclosure discloses a startup control method, apparatus and device for PCI devices in an ARM server and a non-transitory computer-readable storage medium. During boot-up, segment numbers corresponding to PCI devices and PCI link bridge bus serial numbers corresponding to the PCI devices in PCI device drivers for the PCI devices connected to the ARM server are checked. The segment number corresponding to each of the PCI link bridge bus serial numbers in an advanced configuration and power management interface protocol is configured according to the segment number and the PCI link bridge bus serial number corresponding to each of the PCI devices. System resources are allocated to the PCI devices according to the configured segment numbers.
