Custom Linux kernel system for quick change

Abstract

The invention provides a custom Linux kernel system for quick change. The custom Linux kernel system is provided with a self-compiling kernel patch module, a memory root file system module, a kernel configuration file module and a kernel compiling module; before executing a compile script by the memory root file system, the memory root file system is complied and stored in a custom way; the kernel configuration file module is used for storing a kernel configuration file in a custom way before executing the compile script; the kernel patch module is used for pre-storing the modification of a Linux kernel in a development process before executing the compile script and a target kernel patch is required; and the kernel compiling module is used for pre-compiling the compile script before executing the compile script in a custom way. The custom Linux kernel system for quick change provided by the invention can effectively reduce the coupling degree of a kernel used by network equipment and an original kernel, accurately and reliably realize rapid transplantation and replacement of different Linux kernel versions, improve the efficiency of kernel version upgrade of the network equipment, and realize the fast support for new hardware drive or new characteristic functions.

Description

technical field [0001] The invention relates to a Linux kernel update technology, in particular to a custom Linux kernel system for rapid replacement. Background technique [0002] Linux is a set of Unix-like operating system that is free to use and spread freely. Users can obtain it for free through the Internet or other channels, and can modify its source code arbitrarily, which makes Linux system widely used in some network devices, such as switches, Servers, firewalls, and network devices all have their own functional characteristics. The development of functional characteristics in user mode sometimes requires the support and synchronous modification of the Linux kernel. This involves the self-compiled Linux kernel system, and the modification and compilation workload of the Linux kernel will increase With the increase in the complexity of network device functions, and the hardware update in today's network era is very fast, and the version of Linux is released very fre...

[0002] Linux is a set of Unix-like operating system that is free to use and spread freely. Users can obtain it for free through the Internet or other channels, and can modify its source code arbitrarily, which makes Linux system widely used in some network devices, such as switches, Servers, firewalls, and network devices all have their own functional characteristics. The development of functional characteristics in user mode sometimes requires the support and synchronous modification of the Linux kernel. This involves the self-compiled Linux kernel system, and the modification and compilation workload of the Linux kernel will increase With the increase in the complexity of network device functions, and the hardware update in today's network era is very fast, and the version of Linux is released very frequently. Sometimes we have to replace or upgrade the Linux kernel in order to support new hardware drivers or new features. version, and due to some modifications to the kernel source code due to the development of network device functions, it is tightly coupled with the original kernel, and the codes of different versions of the kernel are very different

[0003] In the current self-compiled Linux kernel system, the modification and compilation workload of the Linux kernel will increase with the complexity of the network device functions, and some modifications to the kernel source code due to the development of network device functions lead to tight coupling with the original kernel, and different The codes of the different versions of the kernel are very different, which brings great difficulty and workload to the transplantation and replacement of the Linux kernel
