Abstract

The embodiment of the invention discloses a kernel crash recovery method and device, equipment and a storage medium, and the method comprises the steps that: when a main kernel crashes, the main kernel controls a processor to store the context of a normal thread which is being executed; after the context of the normal thread is stored, the main kernel initializes a loaded standby kernel in a first memory area, wherein the first memory area is a memory area reserved by the main kernel in a physical memory; after initialization is completed, the standby kernel obtains the context of the normal thread by accessing the kernel data structure of the main kernel; and the standby kernel recovers the running states of all the processes according to the context of the normal thread. In the embodiment of the invention, the standby kernel is directly started after the main kernel crashes in a mode of switching the main kernel and the standby kernel, and the whole operating system does not need to be restarted by executing a BIOS program, so that the system recovery time can be saved, and the data loss is avoided.

Description

technical field [0001] The embodiments of the present application relate to but are not limited to the computer field, and in particular, relate to a kernel crash recovery method, device, device, and storage medium. Background technique [0002] As modern operating systems become more and more complex, various errors will inevitably occur, and kernel errors in the operating system are more serious. Once a serious error occurs in the kernel, such as a kernel crash, the default operation of the operating system is to restart the entire system, and restarting the system will result in: 1) business interruption; 2) possible data loss. Contents of the invention [0003] In view of this, embodiments of the present application provide a kernel crash recovery method, device, device, and storage medium. [0004] The technical scheme of the embodiment of the application is realized in this way: [0005] On the one hand, the embodiment of the present application provides a kernel c...
