Embodiment Construction

[0045] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0046] In the prior art, in the process of system development and device driver development, the code can be debugged. This is because the failure of the code will cause problems in the corresponding parts of the system, and the function cannot be realized at the slightest, and the entire system will be affected at the worst. of normal operation. Through debugging...

Abstract

The embodiment of the present application discloses a method and device for processing the linux kernel. By obtaining the non-maskable interrupt NMI, in response to the interrupt, the debugging information of the linux kernel is obtained, and / or, in response to the interrupt, a preset operation is performed on the linux kernel . Since NMI is an interrupt that the processor cannot mask, when the code in the kernel mode fails and causes a system exception, the processor can still obtain the NMI interrupt. In response to the NMI, the processor can obtain the debugging information of the linux kernel and / or The kernel performs preset operations. Among them, by analyzing the debugging information of the linux kernel, the debugging method of the kernel state code can be obtained, so as to realize the debugging of the kernel state code, and the adjustment of the linux kernel can be realized by performing preset operations on the linux kernel, so as to alleviate code failures The impact on the linux kernel is conducive to the acquisition of debugging information and the debugging of kernel mode code, and improves the stability of linux kernel operation.

Description

technical field [0001] The present application relates to the field of computer application technology, in particular to a method and device for processing a linux kernel. Background technique [0002] In the process of system development and device driver development, the code can be debugged. This is because the failure of the code will cause problems in the corresponding parts of the system. At least the functions cannot be realized, and at worst it will affect the normal operation of the entire system. Through debugging, you can modify the grammatical errors or logical errors of the code, so that the modified code can be put into use. [0003] During the development of subsystems and device drivers in the linux kernel, such as the development of memory or block devices, a fault in the kernel state code will cause an abnormality in the linux kernel, which will have a serious impact on the entire system, for example, it may cause The entire system is abnormal, down or stu...
