Linux INITRAMFS 与 INITRD - CodeAntenna
Webb制作initramfs文件，它是多个文件通过cpio打包和gzip压缩的文件，是一个cpio格式的内存文件系统。 $ find.-print0 cpio --null -ov --format = newc gzip-9 >.. /initramfs.cpio.gz 使用QEMU启动ARM32 Linux内核. ARM Linux内核镜像和initramfs都准备好，就可以使用QEMU启动linux内核了。 In Linux, the initrd (initial RAM disk) and initramfs (initial RAM File System) commands are different methods we can use to load a temporary root file system to the RAM or system memory for successful booting. We need either an initrd or initramfsfile system to load the kernel into memory and mount the … Visa mer initrd gives us the ability to load a RAM disk by the bootloader. The loaded RAM disk is mounted as the root file system, and different programs are run from it. We can also mount a new root file system from a different … Visa mer We can use initrd for Linux kernels 2.4 and lower. Conversely, initramfsis for kernels 2.6 and above. Compiling initrdinto the kernel requires at least one filesystem driver, which increases boot-time flexibility, simplicity, and … Visa mer initramfs is a cpio archive file of the initial file system that is loaded to memory. This loading happens after the kernel finishes starting the system, and before the user-space begins the initprocedure. The contents of initramfs … Visa mer In this tutorial, we’ve taken a closer look at what initrd and initramfsmean and how to differentiate them. We also looked at the key role they both … Visa mer planets part of dr. who universe
如何在kernel启动后，加载initramfs_Jarvis000的博客-CSDN博客
Webbcpio的格式非常简单，内核的解压代码也非常少。这种启动方式虽然也叫initrd,但是用的是cpio格式的initrd,和上面ramdisk格式的initrd区别很大，为主流的启动方式，init进程启动以后可以再执行额外查找并挂载文件系统的操作，只不过这些都是用户空间的事了。 http://www.duoduokou.com/linux-kernel/list-49.html Webb构建正确的开发环境，对写驱动程序非常的重要。错误的开发环境，编写出的驱动程序不能正确运行。特别是关于内核版本的问题，内核版本不匹配，会使驱动程序不能在系统中运行。 planets ruled by mercury
