kernel好資料

 

晚上瀏覽網頁的時候， 發現了一些好東西， 尤其是看到了趙珂的blog，真的不錯。  也找到了一些資料， 比如kernel的performance ，什麼的。  Anatomy of the Linux kernel ,好在， 文章的後面提供了很多的連結， 非常不錯。 http://www.ibm.com/developerworks/library/l-linux-kernel/index.html?ca=dnw-827 Anatomy of the Linux slab allocatorhttp://www.ibm.com/developerworks/linux/library/l-linux-slab-allocator/ Going further This article just scratched the surface of the Linux kernel architecture and its features and capabilities. You can check out the Documentation directory that's provided in every Linux distribution for detailed information about the contents of the kernel. Be sure to check out the Resources section at the end of this article for more detailed information about many of the topics discussed here. Resources Learn The GNU site describes the GNU GPL that covers the Linux kernel and most of the useful applications provided with it. Also described is a less restrictive form of the GPL called the Lesser GPL (LGPL). UNIX, MINIX and Linux are covered in Wikipedia, along with a detailed family tree of the operating systems. The GNU C Library, or glibc, is the implementation of the standard C library. It's used in the GNU/Linux operating system, as well as the GNU/Hurd microkernel operating system. uClinux is a port of the Linux kernel that can execute on systems that lack an MMU. This allows the Linux kernel to run on very small embedded platforms, such as the Motorola DragonBall processor used in the PalmPilot Personal Digital Assistants (PDAs). "Kernel command using Linux system calls" (developerWorks, March 2007) covers the SCI, which is an important layer in the Linux kernel, with user-space support from glibc that enables function calls between user space and the kernel. "Inside the Linux scheduler" (developerWorks, June 2006) explores the new O(1) scheduler introduced in Linux 2.6 that is efficient, scales with a large number of processes (threads), and takes advantage of SMP systems. "Access the Linux kernel using the /proc filesystem" (developerWorks, March 2006) looks at the /proc file system, which is a virtual file system that provides a novel way for user-space applications to communicate with the kernel. This article demonstrates /proc, as well as loadable kernel modules. "Server clinic: Put virtual filesystems to work" (developerWorks, April 2003) delves into the VFS layer that allows Linux to support a variety of different file systems through a common interface. This same interface is also used for other types of devices, such as sockets. "Inside the Linux boot process" (developerWorks, May 2006) examines the Linux boot process, which takes care of bringing up a Linux system and is the same basic process whether you're booting from a hard disk, floppy, USB memory stick, or over the network. "Linux initial RAM disk (initrd) overview" (developerWorks, July 2006) inspects the initial RAM disk, which isolates the boot process from the physical medium from which it's booting. "Better networking with SCTP" (developerWorks, February 2006) covers one of the most interesting networking protocols, Stream Control Transmission Protocol, which operates like TCP but adds a number of useful features such as messaging, multi-homing, and multi-streaming. Linux, like BSD, is a great operating system if you're interested in networking protocols. "Anatomy of the Linux slab allocator" (developerWorks, May 2007) covers one of the most interesting aspects of memory management in Linux, the slab allocator. This mechanism originated in SunOS, but it's found a friendly home inside the Linux kernel. "Virtual Linux" (developerWorks, December 2006) shows how Linux can take advantage of processors with virtualization capabilities. "Linux and symmetric multiprocessing" (developerWorks, March 2007) discusses how Linux can also take advantage of processors that offer chip-level multiprocessing. "Discover the Linux Kernel Virtual Machine" (developerWorks, April 2007) covers the recent introduction of virtualization into the kernel, which turns the Linux kernel into a hypervisor for other virtualized operating systems.
