Abstract

The embodiment of the invention provides a method and a device for processing system crash. The method comprises the following steps: the system starts to perform a crash processing flow after system crash; in the performing process of the crash processing flow, whether the crash processing flow is performed correctly is judged according to a preset policy; if the crash processing flow is performed correctly, a dog feeding operation is performed on a watchdog so that the crash processing flow can be completed; if the crash processing flow is not performed correctly, the watch dog is triggered to reset the system so that the performing of the crash processing flow can be terminated. According to the method for processing system crash, when the crash processing flow is performed correctly, the crash processing flow can be performed completely; when the crash processing flow is not performed correctly, the watchdog is triggered to reset the system so that the reliability of the system cannot be affected.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer systems, and in particular to a method and device for dealing with system crashes. Background technique [0002] In a computer system, in order to enable the system to automatically recover under abnormal conditions, a watchdog circuit (hereinafter referred to as a watchdog for short) is generally introduced. The working principle of the watchdog is: there is a counter inside the watchdog. When the watchdog is started, the counter automatically starts counting. After a certain period of time, when the counter reaches the set threshold, a reset signal will be generated to restart the system. Therefore, in order to enable the system to operate normally, it is necessary to clear the counter before the watchdog counter reaches the set threshold. This operation is called feeding the dog. [0003] Generally, in the system, the method of using the watchdog is: 1. During the system start...
