parameters may be changed at runtime by the command "echo -n ${value} > /sys/module/${modulename}/parameters/${parm}". The parameters listed below are only valid if certain kernel build options were enabled and if respective hardware is present. The text in square brackets at the beginni...
Ramdisk相关的启动参数: initrd #指定初始化ramdisk的位置,initrd=filename noinitrd #不使用initrd的配置,即使配置了initrd参数 初始化相关启动参数: init #在启动时去执行的程序,init=filename,默认值为/sbin/init PCI相关的启动参数: pci #pci相关的选项,我常使用pci=assign_buses,也使用过pci=nomsi SELinux相...
如何解析Linux内核的cmdline参数? Kernel启动时会解析cmdline,然后根据这些参数如console root来进行配置运行。 Cmdline是由bootloader传给kernel,如uboot,将需要传给kernel的参数做成一个tags链表放在ram中,将首地址传给kernel,kernel解析tags来获取cmdline等信息。 Uboot传参给kernel以及kernel如何解析tags可以看我的另一篇...
在linux的源代码中,有这样的一个文档Documentation/kernel-parameters.txt,它介绍了kernel的各个参数及其意义。 其次,kernel启动参数以空格分隔,而且是严格区分大小写的(如:mem和MEM是不一样的)。 再次,对于module特有的kernel参数写法是这样的,[module name].[parameter=XX],例如,igb.max_vfs=7这个kernel启动参数的...

This document describes common Linux kernel parameters and how to view and modify them.Modify the kernel parameters only if the parameter settings affect your services. I
Modify the kernel parameters that you have to adjust by editing the /etc/sysctl.conf file. If this file does not exist, create it. The following lines are examples of what must be placed into the file: #Example for a computer with 16GB of RAM: kernel.shmmni=4096 kernel.shmmax=17179869184...

交叉编译工具前缀(比如"arm-linux-"相当于使用"make CROSS_COMPILE=arm-linux-"进行编译).除非你想配置后默认自动进行交叉编译,否则不要使用此选项. Local version - append to kernel release CONFIG_LOCALVERSION 在内核版本后面加上自定义的版本字符串(最大64字符),可以用"uname -a"命令看到 ...
