Also I'm currently not seeing any real differences between cpu-clock and task-clock events. They both seem to count the time elapsed when the task is running on a CPU. Am I wrong ? 不,弗朗西斯已经注意到了,我可能在添加 多pmu 的东西,它在我的待办事项 list 上看(弗朗西斯也递给我 一个小...
The difference between Linux and Windows begins with their history and evolution. At one time, Windows was the dominant desktop operating system, in an era where the desktop was the context to most computing. The advent of Local area networks (LANs), the Internet, and the World Wide Web inf...

Ubuntu vs Linux Linux is a family of Unix-like operating systems. All the members in this family include a Linux kernel. Ubuntu is a variation of one of th
1. kmalloc()分配的内存处于3GB~high_memory之间的一段连续内存,这段内核空间与物理内存的映射一一对应2. Linux处理内存分配通过创建一套固定大小的内存对象池。分配请求被这样来处理,进入一个持有足够大的对象的池子并且将整个内存块递交给请求者。驱动开发者应当记住的一件事情是,内核只能分配某些预定义的,固定大小...
A Linux® distribution, or distro, is an installable operating system built from the Linux kernel, supporting user programs, and libraries. Each vendor or community's version is a distro. Because the Linux operating system is open sourced and released under the GNU General Public License (GPL...
Post stating point wise differences between LVM and LVM2 explained. This is one of the frequently asked question for Linux interview.
