Problems solved by technology

A process running in the server system can read data in a device connected to CPU 1 through CPU 1. When there is a problem with the device itself, such as damage to the device or a problem with the interface slot into which the device is inserted , CPU 1 will time out when reading data on the device (transaction timeout), CPU 1 generates an internal error event (IERR error), and this IERR error event will be broadcast to all CPUs in the server system, which in turn will cause the entire server to reboot

Abstract

The invention discloses a data processing method and electronic equipment. The data processing method comprises the steps that when a first processor breaks down for obtaining data from first equipment, a fault is analyzed through a first operating system, so that a fault source causing the fault is obtained; when the first operating system determines that the fault source of the fault is a device associated with the first equipment, a first target progress is determined, the first target progress is controlled to be closed, and the first target progress is a progress for triggering the first processor to obtain data from the first equipment. The data processing method and the electronic equipment can at least reduce restart probability, and avoid unnecessary restart.

Description

technical field [0001] The invention relates to data processing technology, in particular to a data processing method and electronic equipment. Background technique [0002] In a server with multiple CPUs, each CPU has a certain number of interfaces such as PCIE (Peripheral Component Interconnect Express) interfaces, and each interface can be connected to a corresponding device. A process running in the server system can read data in a device connected to CPU 1 through CPU 1. When there is a problem with the device itself, such as a damaged device or a problem with the interface slot into which the device is inserted , CPU 1 will time out when reading data on the device (transaction timeout), CPU 1 generates an internal error event (IERR error), and this IERR error event will be broadcast to all CPUs in the server system, which in turn will cause the entire server to reboot. How to avoid the restart of the whole server when there is a problem with the device that the CPU a...
