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 lsmod command lists the loaded kernel modules. In emergency cases, when the system fails to boot due to e.g. broken modules, specific modules can be enabled or disabled by modifying the kernel boot parameters list (for example, if using GRUB, by pressing 'e' in the GRUB start menu, then editing the kernel parameter line).
In FreeBSD, NetBSD, OpenBSD, DragonFly BSD, and Darwin/Mac OS X, the parameter net.inet.ip.forwarding can be set to 1 to enable this behavior. In Linux, the parameter is called net.ipv4.ip_forward. In most systems, the command sysctl -w parameter=1 will enable a certain behavior. This will persist until the next reboot. If the behavior should ...
The proc filesystem (procfs) is a special filesystem in Unix-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory.
The Direct Rendering Manager and KMS are part of the Linux kernel. The KMS does only the mode setting. The KMS does only the mode setting. Mode setting is a software operation that activates a display mode (screen resolution, color depth, and refresh rate) for a computer's display controller by using VESA BIOS Extensions or UEFI Graphics ...
Configfs is for creating, managing and destroying kernel objects from user-space, and sysfs for viewing and manipulating objects from user-space which are created and destroyed by kernel space. [2] It is typically mounted at /sys/kernel/config (or more rarely at /config ).
Set up color for ls: install: Copies files and set attributes ln: Creates a link to a file ls: Lists the files in a directory mkdir: Creates a directory mkfifo: Makes named pipes (FIFOs) mknod: Makes block or character special files: mktemp: Creates a temporary file or directory mv: Moves files or rename files realpath
When initially booted, a computer system loads its kernel into memory.At this stage device drivers present in the kernel are set up to drive relevant hardware. Such drivers, as well as other elements within the kernel, may produce output ("messages") reporting both the presence of modules and the values of any parameters adopted.
