testmodule-y:=file-a.ofile-b.oobj-m+=testmodule.o 然后在当前目录下执行 "make -C /lib/modules/<kernel-version>/build M=$(pwd) modules" 即可生成 testmodule.ko 文件。 为什么内核模块的 Makefile 可以如此简洁,这中间都发生了些什么?让我们来拆解下这个过程。 编译 在compile 这块,内核基于普通的...
通常发行版的内核不会使能这个模块,需要启用内核 CONFIG_LKDTM 选项,在 menuconfig 的路径是: Kernel hacking -> RunTime Testing -> Linux Kernel Dump Test Tool Module 最好编译成模块,然后加载模块时,通过模块参数指定崩溃位置和崩溃原因,即可造成所需的内核崩溃。 5. crash 命令 crash 是一个强大的交互式工...
编译内核(Compile the Kernel) Linux内核负责管理/调度所有的系统资源和设备,并为应用程序提供服务。要想让播放机支持更多的设备,比如USB无线网卡,必需从内核入手。Linux支持动态加载模块,这些模块其实也是内核的一部分,只不过是被模块化罢了。模块化的好处之一是可以在需要时才加载模块,不需要时可以卸载,释放其占用的内...
