A driver module upgrade method and device based on linux system

Abstract

The present invention discloses a Linux system based drive module upgrading method. The method comprises: receiving a drive module upgrading instruction, and determining an original version and an upgraded version of a target drive module corresponding to the drive module upgrading instruction; acquiring a depending module of the target drive module and a dependency relationship between the target drive module and the depending module; unloading the original version of the target drive module and the depending module according to the dependency relationship; and loading the upgraded version of the target drive module and the depending module according to the dependency relationship. The present invention further provides a Linux system based drive module upgrading apparatus. With adoption of the Linux system based driving module upgrading method and apparatus provided by the present invention, a drive module upgrading problem in the Linux system is optimized, so that stability and reliability of the system can be improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for upgrading a driver module based on a Linux system. Background technique [0002] For set-top boxes based on the Linux operating system, when updating the driver module, it is necessary to uninstall the old version of the driver module and then load the new version of the driver module. If the old version of the driver module still depends on other modules, then it is also necessary to uninstall A module that a driver module has dependencies on. When loading a new version, it is also necessary to load the driver module of the new version and its dependent modules sequentially according to the dependencies. In the prior art, the Linux command provides a modprobe command, which can automatically process loadable modules, that is, automatically determine the sequence of modules to be loaded and load the corresponding modules in sequence.

Problems solved by technology

[0003] However, the modprobe command is not versatile enough. In many tailor-made Linux systems, the modprobe command cannot be used. As a result, when the driver module is updated, the driver module cannot be uninstalled and loaded in the correct order, which may result in the need to restart the set-top box to Initialize the driver module, or even cause the driver module to fail to operate, resulting in unstable system operation and affecting system reliability

On the other hand, the modprobe command needs to save the file fixedly, which requires a certain amount of space and dependencies. If the dependencies are destroyed or the production fails, the correctness of the driver module will be affected.
