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 .
Windows Subsystem for Linux (WSL) is a feature of Microsoft Windows that allows the use of a GNU/Linux environment from within Windows, foregoing the overhead of a virtual machine and being an alternative to dual booting.
An image of this initial root file system (along with the kernel image) must be stored somewhere accessible by the Linux bootloader or the boot firmware of the computer. This can be the root file system itself, a boot image on an optical disc , a small partition on a local disk (a boot partition , usually using ext2 or FAT file systems), or a ...
Generally the operating system provides a library that sits between the operating system and normal user programs. Usually it is a C library such as Glibc or Windows API. The library handles the low-level details of passing information to the kernel and switching to supervisor mode. System calls include close, open, read, wait and write.
On May 2, 2017, Microsoft unveiled Windows 10 S (referred to in leaks as Windows 10 Cloud), a feature-limited edition of Windows 10 which was designed primarily for devices in the education market (competing, in particular, with ChromeOS netbooks), such as the Surface Laptop that Microsoft also unveiled at this time. The OS restricts software ...
The role of KMS (Kernel mode-setting), Linux example Wayland compositors require KMS (and also OpenGL ES and EGL ) evdev was the Linux kernel module that receives data from various Input devices such as Keyboard, Mouse, Touch-Pad, etc. Nowadays, this is the libinput module (for X and Wayland).
The term user space (or userland) refers to all code that runs outside the operating system's kernel. [2] User space usually refers to the various programs and libraries that the operating system uses to interact with the kernel: software that performs input/output, manipulates file system objects, application software, etc.
The Windows NT kernel is a hybrid kernel; the architecture comprises a simple kernel, hardware abstraction layer (HAL), drivers, and a range of services (collectively named Executive), which all exist in kernel mode. [1] User mode in Windows NT is made of subsystems capable of passing I/O requests to the appropriate kernel mode device drivers ...
