在linux内核中,linux_head使用相当普遍,有许多地方对list_head做了详细的描述,这里就不赘述了,其核心是 通过list_head在struct中的偏移量找到当前struct的地址。
领域特定语言(DSL) Linux Kernel编程 领域特定语言介绍 wikipedia对事件驱动编程的定义: A domain-specific language (DSL) isa computer language specialized to a particular application domain. This is in contrast to a general-purpose language (GPL), which is broadly applicable across domains, and lacks s...
不符合编码规范的commit是完全无法进入Linux内核主线的。 《Linux kernel coding style》是内核开发团队发布的编码规范,原文有20条,这里摘录通用的C语言编码规范12条,供大家参考。 第1条,使用8个字符宽度的制表符(tab)作为缩进。有些人认为,8字符宽度的缩进会使代码向右移动较远,Linux的看法是,如果需要3级以上的...

第1个文件: arch/arm/kernel/head.S 链接脚本: arch/arm/kernel/vmlinux.lds head.S 主要完成了如下工作. __lookup_machine_type 会将 theKernel 传入的单板类型与内核支持的单板类型逐一比较. .arch.info.init 这一个段存放的就是内核支持的单板类型.定义在 ./arch/arm/kernel/vmlinux.lds ...
对于ARM平台,似乎位于 kernel\include\asm-generic\vmlinux.lds.h 这个段中数据的数据结构: kernel_param结构体的定义是: 点击(此处)折叠或打开 36 struct kernel_param_ops { 37 /* Returns 0, or -errno. arg is in kp->arg. */ 38 int (*set)(const char *val, const struct kernel_param *kp)...
Altera Wiki社区发布的μClinux基础开发包中MTD驱动的分区配置文件为linux-2.6/arch/nios2/kernel/config.c,根据相应的硬件芯片修改此文件并运行“make menuconfig”修改内核编译设置后,完成MTD驱动的添加[8]。添加驱动成功后,会在μClinux的dev目录下生成字符设备mtd0或块设备mtdblock0,通过系统调用dd命令,“dd if...
