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...

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,而在切换出去前,会将其in_iowait设置为1,再次被唤醒...
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 lib/find_next_bit.c include/linux/bitops.h ...
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 ...
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...
Linux is a monolithic kernel, meaning that the kernel is responsible for defining a complete interface to the system hardware. However, kernel drivers and features may be compiled as modules which may be loaded or unloaded dynamically on a running system. The kernel includes support for many diff...
http:///wiki/Linux_kernel Development model 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 contain the main, generic branch of development. This branch is offic...
All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may ...
