Because there are numerous revisions and releases of the Linux kernel and new ones are developed at frequent intervals, it is important to have a system for clearly identifying them. A kernel is a program that constitutes the central core of a comput…

在我们使用git来管理Linux Kernel的时候,在编译的时候会在你的kernel version加上git commit number 有时候还会出现dirty字样,字面意思是内核被污染的意思. 使用“uname -a”查看: root@android:/system/lib/modules # /system/bin/busybox uname -a Linux localhost --g6298bd2-dirty # SMP PREEMPT Mon Jan :: CST armv7l…

P30, preemptive  kernel .kernel threading 和Multithreaded application support没太好理解,我想如果设计个多线程的程序来运行运行,恐怕就好理解了.搞清楚了! 在source code里面, arch和include是和硬件相关的代码,arch下面是architecture-specific的文件, include下面放的是内核的所有头文件,其中带有asm前缀的子目录里面是particular architecture的头文件…

The page cache caches pages of files to optimize file I/O. The buffer cache caches disk blocks to optimize block I/O. Page Cache缓存文件内容以优化文件I/O,Buffer Cache缓存磁盘blocks以优化block I/O. 注释:Block 块是用来管理磁盘空间的,而Page 页是针对内存管理,从磁盘读出的数据就缓存在内存页中.当一个块被调入到内存中,它要被存储在…

Originally derived from Red Hat Enterprise Linux (RHEL), Oracle Linux (OL) contains minor differences, such as those necessary to differentiate itself e.g. modified /etc/redhat-release and /etc/issue file content, as well as /etc/enterprise-release, …
