Linux kernel source code each directory function description

Kernel source can go to https://www.kernel.org/to download.

After the download is complete, you will get *.TAR.XZ source package, first use xz-d *.tar.xz decompression, and then use TAR-XVF *.tar to unpack the kernel source code:

[Email protected]:~/workspace$ lslinux-4.1.42 Linux-4.1.42.tar

Enter this directory, there will be many directories:

[email protected]:~/workspace/linux-4.1.42$ lsarch     documentation   init     lib          readme           soundblock    drivers         ipc      MAINTAINERS   Reporting-bugs  toolscopying  firmware       kbuild    Makefile     samples          usrCREDITS  fs              Kconfig  mm           scripts          virtcrypto   include         kernel &nbSp; net          security 

The functions of each catalogue are described below (private dishes from Bird's):

Arch: non-hardware platform related projects, most LED is the CPU category, such as x86, x86_64, Xen virtual support, etc.;

Block: No group training and preparation of the relevant training data, block data is usually LED is a large number of storage media! Also package including similar to ext3 and other file system support is acceptable.

Crypto: The encryption technology supported by the core, such as MD5 is des and so on;

Documentation: Not the core of a bunch of documentation, if the core has a great interest, look at this!

Drivers: Some hardware of the drive program, such as display adapter, network card, PCI-related hardware and so on;

Firmware: micro-scripting (firmware) data for some legacy hardware;

FS: Filesystems supported by the core, such as VFAT, ReiserFS, NFS, etc.;

Include: Some can ridiculed other procedure call header (header) to set 丿 data;

Init: Some core programmes to start the 丿 function, package including mount not init program call Jutting, etc.;

IPC: Fixed 丿 Linux operating system in the process of communication;

Kernel: 丿 core program, core State, Thread, program scheduling (schedule), program number (SIGNLE), etc.

Lib: Some of the Taipa-style libraries;

MM: Non-memory unit related data, packet including swap not virtual memory, etc.;

NET: No network-related acial data, there are firewall modules (net/ipv4/netfilter/*) and so on;

Security: Package including SELinux and other safety training;

Sound: The various modules of the audio;

Virt: Non-virtualized machine-related information, currently the core support is KVM (Kernel base virtual machines)
