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 .
The Linux DTrace implementation is a loadable kernel module, which means that the kernel itself requires no modification, and thus allows DTrace to avoid CDDL vs. GPL licensing conflicts (in its source form, at least). However, once DTrace is loaded the kernel instance will be marked as tainted.
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.
The bootloader will load the kernel and initial root file system image into memory and then start the kernel, passing in the memory address of the image. At the end of its boot sequence, the kernel tries to determine the format of the image from its first few blocks of data, which can lead either to the initrd or initramfs scheme.
A NetWare Loadable Module [1] [2] [3] (NLM) is a loadable kernel module (a binary code module) that can be loaded into Novell's NetWare operating system. NLMs can implement hardware drivers, server functions (e.g. clustering), applications (e.g. GroupWise ), system libraries or utilities.
All device drivers, file systems, etc still run in kernel mode, just like in a monolithic kernel (see hybrid kernel). And how exactly are Windows's loadable kernel drivers different from LKM? The fact that Windows doesn't call them "kernel modules" doesn't mean it doesn't have a similar concept.
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.
LKM or lkm may refer to: 7, Lok Kalyan Marg, the official residence and principal workplace of the Prime Minister of India "Liver Kidney Microsomal", the target of an Anti-LKM antibody; LKM Unia Leszno, a Polish motorcycle racing team; Loadable kernel module, an object code file used to extend the kernel of a computer's operating system
