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.
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.
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.
The second-stage loader (stage2, the /boot/grub/ files) is loaded by the stage1.5 and displays the GRUB startup menu that allows the user to choose an operating system or examine and edit startup parameters. After a menu entry is chosen and optional parameters are given, GRUB loads the linux kernel into memory and passes control to it.
As AMDgpu is part of the monolithic Linux kernel, it is shipped by most Linux distributions directly. The package suite / install script amdgpu-pro, distributed by AMD directly from AMD Radeon Software , ships an AMDgpu kernel module somewhat reliably more up-to-date compared to that of kernels shipped in regular operating system distributions.
ethtool consists of two components, an API within the Linux kernel through which NICs can send and receive parameters through their device driver software, and a userspace API based on the Linux SIOCETHTOOL ioctl mechanism through which application programs can communicate with the kernel to send and receive NIC and NIC driver parameters. Most ...
The term iptables is also commonly used to inclusively refer to the kernel-level components. x_tables is the name of the kernel module carrying the shared code portion used by all four modules that also provides the API used for extensions; subsequently, Xtables is more or less used to refer to the entire firewall (v4, v6, arp, and eb ...
zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM, i.e. a RAM disk with on-the-fly disk compression. The block device created with zram can then be used for swap or as general-purpose RAM disk.
