pci #pci相关的选项,我常使用pci=assign_buses,也使用过pci=nomsi SELinux相关启动参数: enforcing #SELinux enforcing状态的开关,enforcing=0表示仅仅是记录危险而不是阻止访问,enforcing=1完全enable,默认值是0 selinux #在启动时关闭或开启SELinux,selinux=0表示关闭,selinux=1表示开启selinux 另外,还是用max_l...
Even Linus Torvalds, the creator of Linux, the operating system which kick-started the open source revolution in the early 1990s, noted at the Open Source Summit Europe in September that the “kernel maintainers are aging”. FromBBC But Hegseth also talked out of both sides of his mouth, ...
Additionally, a Linux system also treats input and output devices as files. The general understanding is that the files are a sort of in a tree structure on the main hard drive; this is for easy management and order. Most of the files on a Linux system are regular files, regardless of ...
Andrew Morton includes a subset of the mmotm patches in linux-next, which has a head called "linux-next/akpm". There is also a git tree that includes the patches that appear in releases of the mm tree. To get all of the mm patches at any given time, developers still needquilt(quilt...

朱辉:Linux Kernel iowait 时间的代码原理 之前在我热爱的公众号Linuxer看到The precise meaning of I/O wait time inLinux这篇文章,感觉写的不错,就是没有落实到源码上感觉稍微有点晦涩,于是自己读了一下代码。 当task发生iowait的时候,内核对他们的处理方法是将task切换出去,让可运行的task先运行,而在切换...
本文采用Linux 内核v3.10 版本 x86_64架构 位图(Bitmap)在 Linux 内核中使用非常广泛,比如用来标识中断是否已安装处理程序(used_vectors)、处理器是否在线(cpumask)等等。内核中,位图相关的接口及实现主要在以下几个文件中: include/linux/bitmap.h lib/bitmap.c ...
linux-next和snapshot,都是代码提交周期结束之前生成的快照 用于给Linux代码贡献者们做测试。 Development model开发模式 The current development model of the Linux kernel is such that Linus Torvalds makes the releases of new versions, also called the "vanilla" or "mainline" kernels, meaning that they ...
built stand-alone either 'in tree' (within the directory structure of the linux kernel) or 'out of tree' (aka 'external') meaning it exists in a directory of its own outside of the linux source tree.Kernel headers are not needed to build kernel modules, use the kernel source for this...
In particular, the task priority register (TPR) of each chip is initialized to a fixed value, meaning that the CPU is willing to handle every kind of IRQ signal, regardless of its priority. The Linux kernel never modifies this value after its initialization. All task priority registers ...
