Abstract

The invention discloses a PCIE card management method, which comprises the following steps: when a target PCIE card is pulled out, receiving a non-in-place signal reported by a port where the target PCIE card is located, and triggering PCIE hot plug interruption for the target PCIE card; verifying whether an event that the PCIE external plug-in card is pulled out occurs by detecting the state value of the register; and if yes, sending PCIE hot plug interruption to a kernel mode service corresponding to the target PCIE card so as to enable the kernel mode service to perform a removal operation of the target PCIE card, and notifying a user mode service corresponding to the target PCIE card through the kernel mode service so as to enable the user mode service to terminate the current task. By applying the scheme of the invention, the hot plug of the PCIE card is supported. The invention discloses a PCIE card management system, equipment and a storage medium, which have corresponding technical effects.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a management method, system, equipment and storage medium of a PCIE card. Background technique [0002] At present, more and more devices communicate using the PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) bus protocol. For example, in the era of cloud computing, massive data needs to be written and written between different host devices. Data exchange generally uses FC (Fibre Channel, Fiber Channel) networks or Ethernet networks, which have high bandwidth, high reliability, and high stability. , can resist electromagnetic interference, and is easy to build large-scale data transmission and communication networks. When constructing these networks, the PCIE bus protocol is usually used to realize data transmission between the CPU and the FC network or the Ethernet network. [0003] When the PICE card is running for ...
