Problems solved by technology

The number and attributes of the devices are statically set and cannot be modified online. If a VF is modified, all VFs under the same PF will be affected, which cannot meet the requirement of the ECBMS for the dynamic configuration of PCIe devices to take effect immediately.

Abstract

The present invention provides a system and method for dynamically configuring PCIe terminal equipment. The system includes: a PCIe virtualization module, an external debugger and an embedded processor. By simulating a PCIe switch device, further simulating multiple devices connected to its downstream ports Terminal equipment, and provide external debuggable, internal programmable development support, realize dynamic configuration and unified management of PCIe terminal equipment through the simulation of PCIe switches; external debugging interface, internal embedded processor and programmable state machine, The joint control method of stages and tasks is adopted to effectively meet the needs of debugging, application, update, comprehensive, flexible, real-time response and processing of PCIe transaction layer messages under abnormal conditions; IO processing in the PCIe virtualization module The corresponding functional design in the module supports two IO operation modes of device IO and host IO, which improves the efficiency of IO operation.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a system and method for dynamically configuring PCIe terminal equipment. Background technique [0002] In current data center application scenarios, elastic bare metal servers gradually occupy more proportions, and users rent physical servers in an elastic manner similar to cloud services. Different from the traditional server leasing model, while providing complete I / O resources, ECS Bare Metal Server also has the flexibility and configurability of cloud services. The user's dynamic configuration of IO resources such as network devices, storage devices, and computing acceleration devices will take effect immediately and be reflected on the rented elastic bare metal server. [0003] The multiplexing of PCIe terminal devices mostly adopts the SR-IOV (Single Root I / O Virtualization) method, using a PF (Physical Functions, physical function) as a template to virtualize multiple VFs (...
