An oversimplification of how a kernel connects application software to the hardware of a computer. A kernel is a computer program at the core of a computer's operating system that always has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. [1]
A high-level comparison of in-kernel and kernel-to-userspace APIs and ABIs The Linux kernel and GNU C Library define the Linux API. After compilation, the binaries offer an ABI. Keeping this ABI stable over a long time is important for ISVs. In computer software, an application binary interface (ABI) is an interface between two binary program ...
A kernel is a component of a computer operating system. [1] A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems.
A hardware abstraction layer (HAL) is an abstraction layer, implemented in software, between the physical hardware of a computer and the software that runs on that computer. . Its function is to hide differences in hardware from most of the operating system kernel, so that most of the kernel-mode code does not need to be changed to run on systems with different hardwa
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.
A function may contain multiple epilogues. Every function exit point must either jump to a common epilogue at the end, or contain its own epilogue. Therefore, programmers or compilers often use the combination of leave and ret to exit the function at any point. (For example, a C compiler would substitute a return statement with a leave/ret ...
system call – is a function to facilitate programs to request services from the kernel eventfd() netlink – socket family used for IPC between kernel and user space processes, designed as the successor of ioctl ; Netlink was added by Alan Cox during Linux kernel 1.3 development as a character driver interface to provide multiple kernel and ...
A built-in function, or builtin function, or intrinsic function, is a function for which the compiler generates code at compile time or provides in a way other than for other functions. [23] A built-in function does not need to be defined like other functions since it is built in to the programming language. [24]
