Kernel update method and device, computer equipment

Abstract

The invention relates to the computer field, and discloses a kernel update method and device, and computer equipment. The computer device executes the kernel update method to update the loadable kernel module in the kernel; firstly, the first interface mapping table is set to invalid, and the invalid first interface mapping table makes the interface module stop sending service requests of business applications to the first The driving logic of the driving logic module, so that the first driving logic module suspends providing driving services for business applications; then replace the first driving logic module in the loadable kernel module with the second driving logic module, and add it in the second interface mapping table Each interface in the interface module and the driving logic in the second driving logic module corresponding to the interface are recorded in . After the loadable kernel module is updated, the second driver logic module executes the driver logic on the new service request forwarded by the interface module according to the second interface mapping table, so as to resume providing driver services for business applications.

Description

technical field [0001] The embodiments of the present invention relate to the computer field, and in particular to a kernel updating method and device, and computer equipment. Background technique [0002] The kernel (English: kernel) of the operating system (English: operating system, OS) is divided into a basic kernel (English: base kernel) and a loadable kernel module (English: loadable kernel module, LKM). [0003] A loadable kernel module provides at least one driver. When the driver of the loadable kernel module needs to be used, temporarily load the file that implements the loadable kernel module in the memory, run the file to realize the driver, and run the file to implement other drivers included in the loadable kernel module . [0004] Since the computer instructions and data for realizing all the drivers in the loadable kernel module are stored in the same file, the implementation method of updating the loadable kernel module in the prior art is: unload the old ...

AI Technical Summary

Problems solved by technology

When updating the loadable kernel module, even if a certain driver in the loadable kernel module is providing driver services for business applications, the communication connection between the loadable kernel module and the business application is still disconnected, so that the business application cannot continue to communicate with the business application. The loadable kernel module sends a business request for the driver service, resulting in the termination of the driver service
