This allows drivers and devices outside of the mainline kernel to continue working after a Linux kernel upgrade. [3] Another benefit of DKMS is that it allows the installation of a new driver on an existing system, running an arbitrary kernel version, without any need for manual compilation or precompiled packages provided by the vendor.
As the Linux kernel matured, the size of the kernels generated by users grew beyond the limits imposed by some architectures, where the space available to store the compressed kernel code is limited. The bzImage (big zImage) format was developed to overcome this limitation by splitting the kernel over non-contiguous memory regions. [citation ...
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
The Linux kernel is a free and open source, [11]: 4 Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix.
Navigate through the kernel features and menuconfig commands. Esc+Esc: Exit menuconfig or cancel the command. ↵ Enter: Activate a command, or expand a branch. y: Compile and include this feature inside of the kernel. m: Compile this feature as a module, separate from the kernel. n: Do not compile the feature. / Search configuration parameter.
A loadable kernel module (LKM) is an executable library that extends the capabilities of a running kernel, or so-called base kernel, of an operating system. LKMs are typically used to add support for new hardware (as device drivers ) and/or filesystems , or for adding system calls .
Netlink is a socket family used for inter-process communication (IPC) between both the kernel and userspace processes, and between different userspace processes, in a way similar to the Unix domain sockets available on certain Unix-like operating systems, including its original incarnation as a Linux kernel interface, as well as in the form of a later implementation on FreeBSD.

windows.h is a source code header file that Microsoft provides for the development of programs that access the Windows API (WinAPI) via C language syntax. It declares the WinAPI functions, associated data types and common macros. Access to WinAPI can be enabled for a C or C++ program by including it into a source file: #include <windows.h>
