Linux 是一个源码开放的操作系统,无论是普通用户还是企业用户都可以编写自己的内核代码,再加上对标准内核的裁剪从而制作出适合自己的操作系统。目前有很多中低端用户使用的网络设备的操作系统是从标准 Linux 改进而来的,这也说明了有越来越多的人正在加入到 Linux 内核开发团体中。
一个或多个内核模块的实现并不能满足一般 Linux 系统软件的需要,因为内核的局限性太大,如不能在终端上打印,不能做大延时的处理等等。当我们需要做这些的时候,就需要将在内核态采集到的数据传送到用户态的一个或多个进程中进行处理。这样,内核态与用户空间进程通信的方法就显得尤为重要。在 Linux 的内核发行版本中没有对该类通信方法的详细介绍,也没有其他文章对此进行总结,所以本文将列举几种内核态与用户态进程通信的方法并详细分析它们的实现和适用环境。
source code 2
-Linux is an open-source operating system, both ordinary users or enterprises, users can prepare their core code, coupled with the standard kernel cutting thereby making up their own operating system. There are a lot of low-end users of the network equipment from the standard operating system Linux is improving from the This also shows that the more and more people are added to the Linux kernel development groups. One or more modules and the realization of general Linux can not satisfy the needs of system software, because the core is too restrictive, such as the terminal can print, can not handle the b
