Abstract

The invention discloses an equipment exception detection method and device. The method comprises the following steps: monitoring the capacity of a PCIe link storage data packet of PCIe terminal equipment through the flow control characteristic of a high-speed serial computer extension bus PCIe; under the condition that the capacity of the data packet reaches a preset threshold value, controlling the PCIe link to be closed, and triggering an error report message, the error report message being an error report message triggered by an error report mechanism of PCIe; and triggering the driver to detect the state of the PCIe terminal device through the error report message so as to determine whether the PCIe terminal device is abnormal or not. According to the method and the device, the technical problem that the downtime risk of the host machine caused by hardware cannot be processed and repaired in time due to slow response of the AER drive program in related technologies is solved.

Description

technical field [0001] The invention relates to the field of equipment detection, in particular to a method and device for detecting equipment abnormality. Background technique [0002] When heterogeneous computing products provide computing services, GPU / FPGA resource sales are provided to virtual machines in a direct way. However, once such hardware itself or the hardware error triggered by improper handling of these hardware inside the virtual machine will cause the PCIe interface to be unavailable. Therefore, the stability, reliability, and security isolation of heterogeneous computing products have always been the top priority. However, in some specific cases, GPU computing service or FPGA service may not respond to the access to GPU / FPGA pass-through device hardware due to hardware instability and unpredictable reasons, and then cause serious system errors. Due to the slow response of the AER driver, it is too late to process the repair The downtime risk of the host ...
