What is Obj Y in makefile?
obj-y += something/ This means that kbuild should go into the directory “something”. Once it moves to this directory, it looks at the Makefile in “something” to decide what objects should be built.
What is M in makefile?
The M= option causes that makefile to move back into your module source directory before trying to build the modules target.
What is Kbuild in kernel?
“kbuild” is the build system used by the Linux kernel. Modules must use kbuild to stay compatible with changes in the build infrastructure and to pick up the right flags to “gcc.” Functionality for building modules both in-tree and out-of-tree is provided.
What is a KConfig file?
What is KConfig? KConfig is a selection-based configuration system originally developed for the Linux kernel. It is commonly used to select build-time options and to enable or disable features, and has now found use in other projects beyond the Linux kernel.

How do I run a kernel module in Linux?
Loading a Module
- To load a kernel module, run modprobe module_name as root .
- By default, modprobe attempts to load the module from /lib/modules/kernel_version/kernel/drivers/ .
- Some modules have dependencies, which are other kernel modules that must be loaded before the module in question can be loaded.
How do I run a Linux Kernel program?
The steps are:
- Get the latest source code from the main kernel.org website.
- Apply the variations to the old source tree to bring it up to the latest version.
- Reconfigure the kernel based on the preceding kernel configuration file you had backed up.
- Build the new kernel.
- Now you can install the new build the kernel.

What is OBJ file used for?
An OBJ file (. obj) contains information about the geometry of 3D objects. The files are used for exchanging information, CAD, and 3D printing. OBJ files can support unlimited colors, and one file can define multiple objects.
How do .OBJ files work?
The OBJ file format is a simple data-format that represents 3D geometry alone — namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices.
